Now you might want to attack one of these (and feel free to send me a message), but even if you’re right, that would still leave more than enough reasons to stay away from HBD.
This list is a good example of the sort of arguments that look persuasive to those already opposed to HBD, but can push people on the fence towards accepting it, so it may be net-negative from your perspective. This is what has happened to me, and I’ll elaborate on why – so that you may rethink your approach, if nothing else.
Disclaimer: I am a non-Western person with few traits worth mentioning. I identify with the rationalist tradition as established on LW, feel sympathy for the ideal of effective altruism, respect Bostrom despite some disagreements, have donated to GiveWell charities on EA advice, but I have not participated more directly. Seeing the drama, people expressing disappointment and threatening to leave the community, and the volume of meta-discussion, I feel like clarifying a few details that may be hard to notice from within your current culture, and hopefully helping you mend the fracture that is currently getting filled with the race-iq stuff.
All else being equal, people who hang around such communities prefer consistent models (indeed, utilitarianism itself is a radical solution to inconsistencies in other ethical theories). This discourse is suffused with intellectual inconsistency, on many levels of varying contentiousness.
On the faint level of moral intuitions, there’s the strange beeline from the poorly supported prior that normalization of beliefs like Bostrom’s will lead to bad effects like discrimination, to the consequentialist decision against entertaining them. It is not clear that Bostrom’s beliefs are harmful in this way, or more likely to encourage a net increase in discrimination than their negation. Arguments from historical precedent have big problems with them: they do not address the direction of causality, or the fact that different cultures can have different reactions to the same information. As it is not considered normal in the modern culture to equate moral worth and ability for individuals of any group, it can be expected that the same will hold should the difference in ability between groups be acknowledged. Arguments from personal distress of users are valid points with regard to community health, but obviously (I hope) incommensurate with the question of global utility, and do not directly weigh on it. So the consequentialist case for not taking Bostrom’s belief in good faith is already suspect.
Perhaps the most obvious level is that specific failings Bostrom is credibly accused of (racist attitude, belief in the racial IQ difference, belief in the validity of IQ measurement) do not depend on HBD. (He has done himself no favors by bringing up eugenics). So it’s bizarre to see many people denounce his beliefs in toto, but support this denunciation with environmentalist explanations of the IQ gap – in effect, conceding the specific factual claim in Bostrom’s old email, or at least demonstrating that it is not beyond the pale by their own standard. To be clear: it is not in doubt that the IQ gap between Black and White Americans exists; and that it is as predictive of outcomes associated with cognitive capacity as IQ measurement is (which is to say, highly predictive – and this, too, is mainstream consensus). People who act indignant about such statements send a huge red flag, demonstrating either general unwillingness to educate themselves or irrational ideological bias on this specific matter. People who bring up irrelevant anti-HBD talking points demonstrate confused reasoning.
Less obviously, the problem is portraying this as an open-and-shut case – a portrayal which doesn’t really survive scrutiny. I don’t know how to put this nicely, but what your list most reminds me of is polemics of sophisticated Creationists in the heyday of New Atheism. It’s a mix of true but irrelevant, misleadingly phrased, blatantly misinterpreting and patently false claims. Instrumentally they are gotchas; structurally, opening moves aimed at people who are not familiar with the debate and are not aware that all those issues had long been answered, and the debate is incredibly mature. Of course, in all such debates both sides can assert that they’ve solved every vulnerability, and this forum isn’t some HBD Central. So I won’t compete in citations, and will just address things a total layman, provided he’s minimally erudite, napkin-numerate, capable of critical thought and aware of basic logical fallacies, could spot, if he were so inclined. You way “Now you might want to attack one of these (and feel free to send me a message), but even if you’re right, that would still leave more than enough reasons to stay away from HBD.” What if we go through every one of these?
Human biodiversity is actually pretty low. Homo sapiens has been through a number of bottlenecks. – maybe true but vacuous. “Pretty” low relative to what baseline? How would we even tell – do we have anything like IQ for other species? Does this genetic fact establish some prior for the magnitude in differences in measurable phenotypic traits between groups? What about individuals? What we do know that people with a priori negligible “biodiversity” – as in, children in ethnically endogamous marriages, even in isolated villages – routinely have large differences in all traits of interest. So how much diversity is needed, really, to introduce some measurable population-level divergence? Likewise for the point about bottlenecks, what of it? Should our layman just conclude that this is an authoritative-sounding technical term?
Human migrations over the last thousand years have been such that literally everyone on Earth is a descendant of literally everyone that lived 7000 years ago whose offspring didn’t die out. This is known as the Identical Ancestors Point. – grossly misleading/false, and doesn’t pass basic sanity check. Is every single unadmixed Indigenous Australian really a descendant of “literally everyone” 7000 years ago, same as every single Han Chinese? But, looking it up, National Geographic says that “Aboriginal Australians are all related to a common ancestor who was a member of a distinct population that emerged on the mainland about 50,000 years ago”, which implies people of other populations are not all related to him. Aha, here’s where your figure comes from: “Rohde, Olson and Chang showed through simulations that, given the false assumption of random mate choice without geographic barriers, the Identical Ancestors Point for all humans would be surprisingly recent, on the order of 5,000-15,000 years ago.” But it is indeed false, there were barriers for the entire history of our species, such as oceans; and how do migrations of the last millenium negate it? More importantly, it’s a quantitative issue. Your link goes on to say: “Thus, even though the Norwegian and Japanese person share the same set of ancestors, these ancestors appear in their family tree in dramatically different proportions. A Japanese person in 5000 BC with present-day descendants will likely appear trillions of times in a modern-day Japanese person’s family tree, but might appear only one time in a Norwegian person’s family tree.” Seeing as every specimen can have novel genetic variants, this should allow for arbitrary magnitude of divergence, no?
“The very-diverse are hunter-gatherer populations who live in clusters scattered across Central and Southern Africa, in Namibia, Botswana, the Congo and a dozen other nations. They include the Khoi, the San, the Mbuti, the Mbenga, the Twa and the Hadza. [...] Save for that isolated half-million very-diverse hunter-gatherer minority, all Sub-Saharan Africans constitute the genetically in-between group of 1.14 billion not-very-diverse humans. [...] The founder population of today’s genetically not-very-diverse Sub-Saharan Africans shows signatures of a population crash, probably with a toll of 50% and probably from an effective breeding population of something like 50,000 people down to 25,000. So out of a founding population on the scale of a very small city 60,000-120,000 years ago, today’s 1.14 billion Sub-Saharan Africans have gone on to people every habitable space of that hugely varied continent. They are significantly more genetically diverse than their relatives on five other continents, but nowhere near as diverse as the neighbors in their midst. [...] 93-98.5% of the ancestry of humans outside of Sub-Saharan Africa (among those with no recent Sub-Saharan African ancestry, obviously) derives from a breeding population of 1,000 to 10,000, which expanded rapidly 60,000 years ago.” So this tells us that a) this measure of diversity is mostly sensitive to minimal sizes of ancient populations, b) people descending from most of those diverse clusters constitute a tiny fraction of African population, and are thus non-central cases of colloquial “Africans”, c) the overwhelming majority of people of SSA ancestry descend from a single breeding population, which can be distinguished from other populations – including the one that had left Africa. The story is more complex, but the point is that this diversity appears not to be a good reason to not recognize [the majority of] Africans as a specific separate group.
4. Race isn’t a valid construct, genetically speaking. It’s not well defined”. – but aren’t we already talking of genomic ancestry? So this is a true but irrelevant objection. Now, people are of course free to believe that conventional self-reported “races”, which are, as is often correctly said, social constructs, do not correspond to continental-level ancestry – although noisily in many cases. I think this is pretty absurd on its face, but anyway, Googling tells us“In mothers self-identified as Black and White, the imputed ancestry proportions were 77.6% African and 75.1% European respectively” in a “diverse” NYC sample, and I’d expect less cosmopolitan groups to show higher figures. However unfit race is for purposes of cutting-edge research, in the aggregate data it is robustly aligned with ancestry, which is well-defined.
5. Intelligence is not well defined. There’s no single definition of intelligence on which people from different fields can agree. – blatantly misinterpreting. The cited paper states: ”...Nevertheless, some definitions are clearly more concise, precise and general than others. Furthermore, it is clear that many of the definitions listed above are strongly related to each other and share many common features” and goes on to propose a unified definition: “Intelligence measures an agent’s ability to achieve goals in a wide range of environments.” Features such as the ability to learn and adapt, or to understand, are implicit in the above definition as these capacities enable an agent to succeed in a wide range of environments. Also it is not clear why we’d even need people from different fields (in this case, psychology and AI research!) to agree on a definition of intelligence to have a useful measurement of human smarts. And this is what has happened with IQ:
6. IQ has a number of flaws. It is by definition Gaussian without having appeared empirically first and the g construct itself has almost certainly no neurological basis and is purely an artifact of factor analysis. – this is just some Gish Gallop. To begin with, I don’t see your link supporting your summarization – except the vague “number of flaws”. If I may, where have you taken this list from? In any case, anything but God has a number of flaws; your link says that “According to Weiten, “IQ tests are valid measures of the kind of intelligence necessary to do well in academic work.”″ and “clinical psychologists generally regard IQ scores as having sufficient statistical validity for many clinical purposes”. It doesn’t seem like there’s any scientific objection as to the validity of IQ as a measurement of what’s casually called smarts and understood to be smarts in the context of this discussion – even though there are weird attempts to drown this fact in caveats. Why is the part about assumed Gaussian even relevant? What would it mean for g to have a neurological basis, and why would that matter in the discussion of HBD? …And the part about g being “purely an artifact of factor analysis” is plain false, far as I can tell. It comes from Cosma Shalizi’s essay that misstates the reason for the existence of positive manifold. “If I take any group of variables which are positively correlated, there will, as a matter of algebraic necessity, be a single dominant general factor… Since intelligence tests are made to correlate with each other, it follows trivially that there must appear to be a general factor of intelligence.” This is just a lie: a great deal of effort has been devoted to making cognitive tests comprehensive and diverse assessments of ability, but positive correlations pop out on their own, even in research informed by Shalizi’s assumptions, e.g. “The WJ-R was developed based on the idea that the g factor is a statistical artifact with no psychological relevance. Nevertheless, all of its subtests are intercorrelated and, when factor analyzed, it reveals a general factor that is no less prominent than those of more traditional IQ tests”. And ”...All 861 correlations are positive. Subtests of each IQ battery correlate positively not only with each other but also with the subtests of the other IQ batteries. This is, of course, something that the developers of the three different batteries could not have planned – and even if they could have, they would not have had any reason to do so, given their different theoretical presuppositions.”
7. Twin studies are flawed in methodology. Twins, even identical twins, simply do not have exactly the same DNA. – again, misinterpreting; there are flaws but the method is not summarily “flawed” just because a section about flaws exists. The first link is a list of objections but in no way does it show or argue that they are decisive, or even apply at all to current methods (there are “responses to critiques” subsections). The second is apparently irrelevant, and was already addressed by another user.
8. Evolution isn’t just mutations and natural selection. Not every trait is an adaptation. (a link to Wiki on “Evolution – Evolutionary processes”) – …okay but how does this even support your case? I’m honestly unsure what the idea here is. Taken literally, your summary suggests that evolution can produce maladaptive changes, so we cannot assume that all (or any) populations will be maximally fit (for their environment). This is a pro-eugenicist take, if anything. Whereas the page itself discusses mechanisms of change in allele frequency and does not have any clear impact on the validity of HBD one way or another.
9. Heritability does not imply genetic determinism. Many things are heritable and do not involve genes.These include epigenetic mechanisms, microbiota, or even environmental stress on germinal cells. – irrelevant/false. The link is to “Heritability – Controversies” with some nitpicks of unclear truth value. The second is a general overview of possible issues with heritability estimates. It does not weigh in on HBD and accepts the premise of variable genetic contributions to human intelligence: As a case in point, consider that both genes and environment have the potential to influence intelligence. Heritability could increase if genetic variation increases, causing individuals to show more phenotypic variation, like showing different levels of intelligence. On the other hand, heritability might also increase if the environmental variation decreases, causing individuals to show less phenotypic variation. This says, concretely, that in more equal environments we will observe more true genetic effects on variation in intelligence, so whatever differences in genetic effects on this trait there are between groups, they will become more pronounced. By the way this is terrible for the anti-HBD position because it means that the state of perfect environmental equality – one could say equality of opportunity – will collapse into genetic determinism (modulo random noise). Your own idea seems to be that non-genetic mechanisms of apparent heritability can be interrupted by a positive environmental intervention. What share of “heritable” variance can it explain, at a maximum? Like, concretely, to what extent do you think the racial IQ gap is explained by microbiota, epigenetic mechanisms and environmental stress on germinal cells? Those are all quantifiable and falsifiable claims, but you just gesture at them. At this point, a dedicated layman looks it up and sees that they can explain very little indeed.
10. We don’t mate randomly, which is an assumption in many genetics studies. – irrelevant applause lights, “genetics bad”. Which studies, and does this matter for HBD? I’ve watched the video; it discusses interactions between psychiatric disorders and such, and states that genetic correlations between traits may be inflated by assortative mating (i.e. people high in trait X marry people high in trait Y). Genetic correlation “is defined as the proportion of the heritability that is shared between two traits divided by the square root of the product of the heritability for each trait”. What is meant here, concretely? Ancestry is not really a “heritable trait”, is it? And race is just a category, plus a bad proxy for ancestry, as far as HBD is concerned.
11. HBD is not generally accepted in academia. – this is just an appeal to authority, plus misleading. It’s a single highly technical paper by some Kevin Bird, “Department of Horticulture Michigan State University”, can it be considered an authoritative source on what academia thinks? And from the abstract, it attacks a very strong form of HBD reasoning, using data that cannot plausibly be conclusive: Evidence for selection was evaluated using an excess variance test. Education associated variants were further evaluated for signals of selection by testing for excess genetic differentiation (Fst). Does it strike you as plausible that we know enough about “education associated variants” to impute effects of prehistoric selection on intelligence? This ought to mean that the science of genetics of intelligence is vastly more mature than people think, than you suggest, too, and that within-group intelligence heritability is understood really well! Why hasn’t this made the news yet? (And how does this address obvious low-tech HBD arguments, such as admixture studies and adoption studies?)
12. Many public HBD figures have been found guilty of fraud. Cyril Burt would literally forge results, while Lynn would take the average of two neighboring countries’ IQ in order to derive “data” from a country’s unknown national IQ. – That’s an isolated demand for rigor. What field doesn’t commit fraud? Were public anti-HBD figures never found guilty of fraud? Is the fraud rate different enough to affect our priors? And your link does not show that Burt’s forgery was positively proven, but it admits that figures of heritability arrived at by independent researchers do not differ from Burt’s, so why should we care? Assuming that a layman could track it down from here, I’ll allow myself to quote Richard Haier (The Neuroscience of Intelligence, Cambridge University press, 2017): Subsequent twin studies done by different investigators around the world with large samples arrive at an average value for the correlation of intelligence scores among identical twins raised apart of .75 (Plomin & Petrill, 1997). Burt’s value was .77. For comparison, based on 19 studies ranging in sample sizes between 26 and 1,300 identical twin pairs, the average value for identical twins raised together is about .86 (see Loehlin & Nichols, 1976, table 4.10, p. 39)… Thus, the .771 “fraud” ends with recognition of overwhelming data from independent researchers that are fully consistent with Burt’s analyses, flawed as they may have been. Any single study, or any one researcher, can be flawed, but the basic conclusion that genes play an important role in intelligence is consistently supported by data from numerous studies of twins, adoptees, and adopted twins. This is an excellent example of looking at the weight of evidence (recall my three laws from the Preface: no story is simple; no one study is definitive; it takes many years to sort out conflicting and inconsistent findings and establish a weight of evidence). … The weight of evidence summarized in this chapter leaves no reasonable doubt. Only extreme ideologues are still in denial. As for Lynn’s country data, well, the same logic applies. Do we have any more trustworthy data? Does it refute Lynn’s? Then why not just refer to it instead? Please don’t say that it’s not very interesting and nobody has bothered to collect proper measurements, IQ and race (or rather, ethnicity) is literally the most painful question in modern science, and it’s evident from such dramas that a great many researchers are emotionally invested in proving the relationship wrong.
Ultimately, exposure to this sort of content has done for me what it has done for this person:
[…] Well, OK, I could believe that; visible traits consistent over entire populations like skin color might differ systematically because of sexual selection or something, but why not leave IQ following the exact same bell curve in each population? There was no specific thing here that made me start to wonder, more a gradual undermining (Gould’s work like The Mismeasure of Man being completely dishonest is one example—with enemies like that…) as I continued to read studies and wonder why Asian model minorities did so well, and a lack of really convincing counter-evidence like one would expect the last two decades to have produced—given the politics involved—if the idea were false. And one can always ask oneself: suppose that intelligence was meaningful, and did have a large genetic component, and the likely genetic ranking East Asians > Caucasian > Africans; in what way would the world, or the last millennium (eg the growth of the Asian tigers vs Africa, or the different experiences of discriminated-against minorities in the USA), look different than it does now? But having said that, and admiring things like Plantinga’s free will defense, and the subtle logical issues in formulating it and the lack of any really concrete evidence for or against Jesus’s existence, do I take the basic question of God seriously? No. The theists’ rearguard attempts and ever more ingenious explanations and indirect pathways of reasons and touted miracles fundamentally do not add up to an existing whole. The universe does not look anything like a omni-benevolent/powerful/scient god was involved, a great deal of determined effort has failed to provide any convincing proof, there not being a god is consistent with all the observed processes and animal kingdom and natural events and material world we see, and so on. The persistence of the debate reflects more what motivated cognition can accomplish and the weakness of existing epistemology and debate.[…]
I want to make it perfectly clear: those question marks in my point-by-point do not actually indicate uncertainty. They could as well have been references to papers. The field really is about as advanced as Bird’s study suggests – only in the direction he disapproves of. But this isn’t the place for it, surely people can go to some edgier venue and ask for receipts. The point I’m trying to make is: you say “Okay, if there’s anyone here who actually believes in HBD, here’s a couple reasons why you shouldn’t.” On an ignorant but moderately skeptical person your little list can, and likely will, have an effect that’s the opposite of what you intend to achieve. To “who actually believes in HBD”, it’s utterly unconvincing. If I may be so blunt, it’s almost as sad as quasi-scientific gotchas of flat earthers.
And this is how all of anti-HBD rhetoric is, in my experience. It crumbles under basic scrutiny, links do not show what they are purported to show, there are simple misunderstandings of what terms mean, there is no coherent epistemology or a single model, there’s suppression of inconvenient evidence, there’s substitution of evidence with confident op-eds in Vox from people who are supposed to be experts (but whose legitimate work doesn’t support their confident claims), there are cascades of internally inconsistent Gish Gallops and other fallacies; worst of all, the reader is assumed to just not be all that bright. It’s a collection of purely reactive objections that might come across as persuasive to like-minded people, but are not battle-tested – and indicate general unwillingness to test one’s beliefs.
I expect very little payoff from this labor. But it would be nice if EAs were to become a little more reserved on this topic, and at least stopped turning off potential recruits with irrefutable displays of irrationality.
84% of surveyed intelligence researchers believe the gaps are at least partially genetic.[1] This statement is not just an appeal to authority, it is also inaccurate.
Why did you reply to MissionCriticalBit when it was I who made that claim? I almost didn’t see it. Also pointing out that the academics who study this stuff for a living don’t believe in it is not fallacious, but rather a very useful piece of information. Anyway, I wanted to give the HBDers another shot so I downloaded the survey (can we all agree that paywalls for publicly funded research is bullshit?) and I have two important things to note: genetic gaps is not equivalent to racial gaps, and the survey itself admits it is unrepresentative. It was an internet survey:
The EQCA was an online survey administered from May 2013 to March 2014.
and had a high nonresponse rate:
a total of 265 responses were received, which produced a response rate of 19.71%.
with respondents who are different than the field as a whole:
In the current study, the EQCA sample leaned slightly to the left (54%, Table 2). The left tilt of the EQCA sample was small compared to the left tilt observed for psychologists overall, who overwhelmingly identify as left-liberal (90% or higher, Duarte et al., 2015). [...] In addition, the EQCA sample was predominantly male (83%), far exceeding the male share of APA membership, which is mostly female (57%, APA Center for Workforce Studies, 2015).
which heavily biases the results in favor of your position:
In contrast, compared to female and left (liberal) experts, male and right (conservative) experts were more likely to endorse the validity of IQ testing (correlations with gender, politics: r = .55, .41), the g factor theory of intelligence (r = .18, .34), and the impact of genes on US Black-White differences (r = .50, .48).
EDIT: To respond to missioncriticalbit below. My comment was about the sentence “HBD is not generally accepted in academia”. The reason I can’t show you a survey that shows you that is the same reason I can’t show you a survey that zoologists don’t believe in unicorns, they don’t engage with it so there is no survey available (even the bad survey by anon rationalist is not about HBD). But I don’t want to make an assertion without citing anything, so what is the best available option? How about an example of a professional biologists with no conflict of interests using publicly available data to create a well received paper that has been seen more than 12000 times that clearly rejects HBD.
Missioncriticalbit just makes assertions without citing anything. The reason I don’t respond and refused to continue to read his reply is not because I am afraid, but because he hadn’t cited anything, didn’t engage with my writings and outright insulted me.
The reason I respond in an edit instead of a reply is because the HBDers have removed half a dozen of my latest comments from the frontpage while taking away a big chunk of my voting-power on this forum. I’m not inclined to give them another way to take away my voting-power, but I don’t want to silence myself, so using the edit button is my workaround.
First, that depends on what you mean by “this stuff”; Bird does not study intelligence nor behavioral genetics for a living, he’s a plant geneticist. Skewed though the survey may be, it’s probably more representative than a single non-expert.
Second, why do you suppose the non-response rate is so high and so skewed? And might it have something in common with your own refusal to continue our conversation on merits of your list?
I suspect that professionals who prefer not to respond, rather than respond in the negative about genetic contributions to the IQ gap, are driven by contradictory impulses: they believe that the evidence doesn’t allow for a confident “100% environmental” response and, being scientists, have problem with outright lying, but they also don’t want to give the impression of supporting socially unapproved beliefs or “validating” the very inquiry into this topic. So they’d rather wash their hands of the whole issue, and allow their less squeamish colleagues to give the impression of moderate consensus in favor of genetic contribution.
Differential response within the survey is again as bad.
The response rate for the survey as a whole was about 20% (265 of 1345), and below 8% (102) for every individual question on which data was published across three papers (on international differences, the Flynn effect, and controversial issues).
Respondents attributed the heritability of U.S. black-white differences in IQ 47% on average to genetic factors. On similar questions about cross-national differences, respondents on average attributed 20% of cognitive differences to genes. On the U.S. question, there were 86 responses, and on the others, there were between 46 and 64 responses.
Steve Sailer’s blog was rated highest for accuracy in reporting on intelligence research—by far, not even in the ballpark of sources that got more ratings (those sources being exactly every mainstream English-language publication that was asked about). It was rated by 26 respondents.
The underlying data isn’t available, but this is all consistent with the (known) existence of a contingent of ISIR conference attendees who are likely to follow Sailer’s blog and share strong, idiosyncratic views on specifically U.S. racial differences in intelligence. The survey is not a credible indicator of expert consensus.
(More cynically, this contingent has a history of going to lengths to make their work appear more mainstream than it is. Overrepresenting them was a predictable outcome of distributing this survey. Heiner Rindermann, the first author on these papers, can hardly have failed to consider that. Of course, what you make of that may hinge on how legitimate you think their work is to begin with. Presumably they would argue that the mainstream goes to lengths to make their work seem fringe.)
This list is a good example of the sort of arguments that look persuasive to those already opposed to HBD, but can push people on the fence towards accepting it, so it may be net-negative from your perspective. This is what has happened to me, and I’ll elaborate on why – so that you may rethink your approach, if nothing else.
Even if you think my reasons failed, why would that push you towards accepting it? HBD is a hypothesis for how the world works, so the burden of proof is on HBD and giving a bad reason not to believe in HBD is not evidence for HBD. To give a very clear example, if someone says ‘I believe in unicorns’, and I say ‘no unicorns do not exist because 1+1=3’ that would fail to be evidence for unicorns not existing, but that does not mean it counts towards evidence for unicorns existing.
Disclaimer: I am a non-Western person with few traits worth mentioning. I identify with the rationalist tradition as established on LW, feel sympathy for the ideal of effective altruism, respect Bostrom despite some disagreements, have donated to GiveWell charities on EA advice, but I have not participated more directly. Seeing the drama, people expressing disappointment and threatening to leave the community, and the volume of meta-discussion, I feel like clarifying a few details that may be hard to notice from within your current culture, and hopefully helping you mend the fracture that is currently getting filled with the race-iq stuff.
Thank you for donating to GiveWell! Unimportant nitpick that has always bothered me: LW has an empiricist tradition, the term ‘rationalist’ is a misnomer.
All else being equal, people who hang around such communities prefer consistent models (indeed, utilitarianism itself is a radical solution to inconsistencies in other ethical theories). This discourse is suffused with intellectual inconsistency, on many levels of varying contentiousness.
I wouldn’t say other ethical theories are internally inconsistent. They might have other attributes or conclusions that you think are bad, but the major ethical theories don’t have any inconsistencies as far as I can tell. Do you have an example?On the other hand I do think Eliezer has some inconsistencies in his philosophy, although it’s hard to tell because he’s quite vague, doesn’t always use philosophical terminology (in fact he isverydismissive of the field as a whole) and has a tendency to reinvent the wheel instead (e.g his ‘Requiredism’ is what philosophers would call compatibilism). Now usually I wouldn’t mind it that much, but since philosophy requires such precision of language if you don’t want to talk past each other, I do think this doesn’t work in his favor.
On the faint level of moral intuitions, there’s the strange beeline from the poorly supported prior that normalization of beliefs like Bostrom’s will lead to bad effects like discrimination, to the consequentialist decision against entertaining them.
I would like to point out that my comment was not about Bostrom.
It is not clear that Bostrom’s beliefs are harmful in this way, or more likely to encourage a net increase in discrimination than their negation. Arguments from historical precedent have big problems with them: they do not address the direction of causality
I mean even if you don’t know which way the arrow of causality points, that’s still an unnecessarily big risk. It’s not particularly altruistic to make statements that have that big a chance of helping racists. You could also spend your time… not doing that. Also even if you reject arguments from historical precedent there is still the entire field of linguistic racism.
As it is not considered normal in the modern culture to equate moral worth and ability for individuals of any group, it can be expected that the same will hold should the difference in ability between groups be acknowledged.
Just because people won’t publicly state it doesn’t mean it doesn’t influence their thinking. Take for example the stereotype of the welfare queen. While not everyone will explicitly state ‘this person has a lower moral worth’ (although some will) the racist stereotyping does lead to black people being harmed both socially and economically. The myth of meritocracy is strong, and people who are seen as unable to ‘pull themselves up by their bootstraps’ are looked down upon.
Arguments from personal distress of users are valid points with regard to community health, but obviously (I hope) incommensurate with the question of global utility, and do not directly weigh on it.
What global utility? Racists want us to talk about this stuff, there are other correlations that are both on firmer ground, have more global utility and aren’t fulfilling the desires of racists.
Perhaps the most obvious level is that specific failings Bostrom is credibly accused of (racist attitude, belief in the racial IQ difference, belief in the validity of IQ measurement) do not depend on HBD. (He has done himself no favors by bringing up eugenics). So it’s bizarre to see many people denounce his beliefs in toto, but support this denunciation with environmentalist explanations of the IQ gap
If you had read my comments you would’ve seen that I both didn’t respond to Bostrom, did respond to HBD and did support the environmental explantation of the IQ gap.
– in effect, conceding the specific factual claim in Bostrom’s old email, or at least demonstrating that it is not beyond the pale by their own standard. To be clear: it is not in doubt that the IQ gap between Black and White Americans exists; and that it is as predictive of outcomes associated with cognitive capacity as IQ measurement is (which is to say, highly predictive – and this, too, is mainstream consensus). People who act indignant about such statements send a huge red flag, demonstrating either general unwillingness to educate themselves or irrational ideological bias on this specific matter. People who bring up irrelevant anti-HBD talking points demonstrate confused reasoning.
My comment didn’t deny the existence of an IQ gap and my comment was responding to sapphire who was talking about HBD specifically and so it wasn’t “irrelevant anti-HBD talking point”. If you’re not engaging with what I actually write I’m starting to think that spending hours on this comment wasn’t the best use of my time.
what your list most reminds me of is polemics of sophisticated Creationists in the heyday of New Atheism. It’s a mix of true but irrelevant, misleadingly phrased, blatantly misinterpreting and patently false claims. Instrumentally they are gotchas
Very civil. It will not surprise you to learn that this does not motivate me to keep reading.
So I won’t compete in citations
Yeah I’m out. *I’m going to spend my time on something else now.
HBD is a hypothesis for how the world works, so the burden of proof is on HBD and giving a bad reason not to believe in HBD is not evidence for HBD.
This logic is only applicable to contrived scenarios where there is no prior knowledge at all – but you need some worldly knowledge to understand what both these hypotheses are about.
Crucially, there is the zero-sum nature of public debate. People deliberately publicizing reasons to not believe some politically laden hypothesis are not random sources of data found via unbiased search: they are expected to cherrypick damning weaknesses. They are also communicating standards of the intellectual tradition that stands by the opposing hypothesis. A rational layman starts with equal uncertainty about truth values of competing hypotheses, but learning that one side makes use of arguments that are blatantly unconvincing on grounds of mundane common sense can be taken as provisional evidence against their thesis even before increasing object-level certainty: poor epistemology is evidence against ability to discover truth, and low-quality cherrypicked arguments point to a comprehensively weak case. Again, consider beliefs generally known to be kooky, and what they bring to bear on the opposition. Their standard of rigor alone is discrediting to what they believe in.
Moreover, I’ve established that, upon checking, some of your links positively provide evidence in favor of HBD, rather than against – at least by the standard of evidence implicit in the phrasing of the list. Returning again to the Identical Ancestors Point, is presented as an Anti-HBD finding in the first place because it implies a very low prior for genetic divergence of populations, migrations somehow averaging it all out: Human migrations over the last thousand years have been such that literally everyone on Earth is a descendant of literally everyone that lived 7000 years ago whose offspring didn’t die out. (Is this the wrong takeaway? What, then, did you mean to say by adding it?) Looking into the actual paper, we see: …For example, a present-day Norwegian generally owes the majority of his or her ancestry to people living in northern Europe at the IA point, and a very small portion to people living throughout the rest of the world. Furthermore, because DNA is inherited in relatively large segments from ancestors, an individual will receive little or no actual genetic inheritance from the vast majority of the ancestors living at the IA point. Not only does this make the original argument invalid (even in a strong absolute sense – there can be zero common inheritance!) – it directly reinforces the HBD conjecture that long-term (i.e. pre-IAP) divergent local adaptation is relevant to current genetic (and trait) differences.
LW has an empiricist tradition, the term ‘rationalist’ is a misnomer.
I agree that this is improper and irritating terminology, because doctrinally, LW asserts its allegiance to empiricism, with all the talk about Bayes-updating on evidence and how rationalists must “win”. But in practice this isn’t so clear-cut: LW is fascinated with armchair thought experiments (that routinely count as evidence to update on), and all the attention devoted to infohazards, Pascal mugging, one-boxing, AI scenarios etc. suggests that they, as a living tradition, are not resilient to speculation the way pure empiricists – say, regular natural scientists – would be. So, not necessarily a misnomer.
the major ethical theories don’t have any inconsistencies as far as I can tell
They are internally consistent, but I think the point of ethical theory is to clarify the intuitively knowable essence of moral action for purposes of nontrivial decisionmaking, not to assert what morality is and derive an arbitrary decision rule from there. Utilitarianism is often criticized for things like the repugnant conclusion, yet non-utilitarian ethical theories routinely produce more grating outputs, because they fail to capture the most significant part of intuitive ethics, which is mostly about harm reduction under conditions of resource scarcity. They are less consistent with ethics given to us in lived experience, so to speak.
even if you don’t know which way the arrow of causality points, that’s still an unnecessarily big risk. It’s not particularly altruistic to make statements that have that big a chance of helping racists. You could also spend your time… not doing that.
No, the extent of the purported risk matters. You are just falling back on the unsupported prior about cost-benefit ratio because you have preemptively excluded all factors that may change the qualitative conclusion of “not doing that”. To give a specific example: under the assumption that HBD is wrong, we must consider disparate outcomes to be a result of some discrimination and devote resources to alleviate it; but if HBD is actually right, this’d necessarily mean that our costly attempts to help low-performing groups are suboptimal or futile (as in, not effective), and that we will have unfairly attributed blame, harming other groups psychologically and materially. Then there are knock-on effects of harming science: for starters, fears of enabling racists can hold back genomic medicine (and population-specific treatment) by increasing hurdles to data collection and access. We do not have a priori knowledge as to which costs are negligible. On a more meta level, Scott Alexander’s parable comes to mind.
IMO it’s a weak argument because for all the racism, black Americans still report the highest self-esteem of all racial groups; and theories of stereotype threat are apparently unsupported by high-quality data; so it isn’t clear what the odds are that some HBD research or whatever would harm people substantially. But even before that – there are laws against hate speech and discrimination, and they can be strengthened if needed; it seems very suboptimal to focus on not developing neutral knowledge only to deny hateful ideologies rhetorical ammo, instead of dealing with them directly. By the way, cannot racists point to censorshipas sufficient evidence of their correctness, if their intent is to spin available facts to their benefit? Actually, doesn’t this enable them to – convincingly – claim that facts are much worse than they are, that the genomic gap in cognitive ability is bigger than the non-zero gap we’d have found (and, I believe, have partially found) with proper research (which is currently prohibited)? And in any case, you have to put racism-driven harms in the context of costs of pretending that HBD is certainly false – that is, under the assumption that we are “just not doing that” and have no clue whether it is or isn’t true.
As an aside, I am personally puzzled by the strong conviction of many that HBD becoming common knowledge could lead to normalization of racial discrimination. This is a normative, not scientific question. Societies with Social Darwinist values do not need HBD to embrace and exacerbate the status quo of disparate power. Societies with ethnocentric values opportunistically oppose and exploit ethnic outgroups regardless of relative merit. Mainstream modern value system depends on the premise of human rights, not equality of capability. We do not hold that it is normal to oppress individuals who are known to be below average in some morally neutral trait (except maybe for an expansive definition of “oppress” and clinical issues having to do with lack of legal capacity), we have a strong revulsion to identity-based discrimination, and we understand the unreasonableness of treating individuals on the basis of average values.
Uncharitably, in the case of EA, this concern may have to do with the strain (common to EA and LW) of conspiratorial elitism and distrust in the democratic process, and with the unconscious belief that intelligence does define moral worth. That’s …not a very popular belief. I would deeply hate it if my cognitive betters acted like they have greater moral worth than myself, and therefore, to be fair, I cannot deny equal moral worth to people of lower ability. Most people correctly believe that they aren’t brilliant, but they’re not so dull as to not arrive at this logic. There are some contingent factors that complicate the picture, but not fundamentally.
Without getting into the weeds of stereotype scholarship, the extent of claimed harms, and the irrational denial of the role of merit in achievement (reasoning in that wiki page doesn’t even begin to address what would happen in a “proper” meritocratic society after a few generations, because it is premised on genes not contributing to achievement; this is a typical case of an unexamined anti-HBD prior leading to policy errors)… I’ll just say that in my opinion both those issues, insofar as they harm anyone, have to do with beliefs about moral qualities. If “Protestant ethic” is alive and prescribes vilification of people of lower morally neutral ability, then that is a problem in its own right and beyond the scope of this conversation. Luckily, Protestant ethic also encourages treating people on a case by case basis.
What global utility?
Crucially, the search for interventions that actually close the IQ gap. As it stands, we have picked low-hanging fruit like lead exposure, malnutrition, iodine deficiency, parasites and such (in developed nations; I expect EA efforts in Africa to keep delivering on this front), and are left with pursuing dead ends of addressing iniquity like the “food deserts” nonsense, or doubling down on stuff like school spending, that has long ran into diminishing or zero returns and is only popular because to point out its inefficacy means to risk being labeled racist. As Nathan Cofnas argues,
...But the reason that these programs, which Kourany rightly says ought to exist, have never been created is not because of racism but because of the taboo on talking about genetic differences among policy makers. No mainstream politician can acknowledge that there are differences that might call for the creation of a program to “work with the strengths and work on the weaknesses of every [ethnic] group to help make them the very best they can be.” It is hereditarians who have advocated these programs and environmentalists who have resisted them.
Ironically, Cofnas got in trouble for this. If the suppression starts this far upstream from the object level, how can our priors be trusted?
there are other correlations that are both on firmer ground, have more global utility and aren’t fulfilling the desires of racists
I sincerely doubt you can prove 1 or 2 (given that your critiques of relevant methodology weren’t persuasive), and it looks like assigning any value to 3, on its own, is pure spite that is best left out of effective altruism. Making racists mad is not, in fact, a positive good, fun as it may be.
If you had read my comments
Have read some. I explicitly say I’m addressing the state of discourse here, more than just your comment. I respond to you in particular when I quote specific passages. Sorry if that was unclear.
did support the environmental explantation of the IQ gap
Again, this is not HBD Central, and it is sufficient to establish that there is legitimate uncertainty, so we cannot fall back on the comfortable prior that costs of repudiating HBD are negligible.
Very civil. It will not surprise you to learn that this does not motivate me to keep reading.
Well, I believe that misleading people, and even wasting people’s time on true but irrelevant, misleadingly phrased, blatantly misinterpreting and patently false claims is a form of rudeness that’s extra obnoxious, because it craftily avoids opprobrium one could earn with trivial show of disrespect. It’s not fair to act indignant about an unflattering comparison after doing that. Even so, I’ve made peace with Brandolini’s law, and kept addressing those claims on the object level, to substantiate my “very civil” summary and so that “EAs were to become a little more reserved on this topic, and at least stopped turning off potential recruits with irrefutable displays of irrationality.” To be honest your reaction isn’t wholly unexpected, but I did hope that I’ve been polite enough to merit some tolerance.
Yeah I’m out.
OK but please think of your stated desire is to persuade those who happen to believe in HBD to disbelieve it. Obviously you’ve failed in my case, but I maintain that flaming out like that is detrimental even as far as fence-sitters are concerned. I believe I’ve provided sufficient receipts for the purpose of showing how your list is inadequate.
It is really not hard to showboat on this topic, by citing from very clearly argued stuff like this or “authoritative” sources like that review or very technical recent papers or just by gesturing in the general direction of environmentalist rhetoric that is… the way I’ve described, and evident in, e.g., this condemnation of Cofnas, mired in (what I hope is obvious after my initial comment) logical fallacies and half-truths and raw indignation. Or one can just say that if this guy is challenged not by rational and empirical arguments but by being repeatedly called a pseudoscientist and getting a page full of personal attacks on him to the top of search results for his name (a page he responds to with an even pettier page), then he may get a lot of uncomfortable stuff right.
My point is not to showboat but to argue that people who pursue this anti-HBD rhetorical strategy, including you, are probably not succeeding, and are doing the community no favors.
I don’t want to engage with your arguments. I strongly think you’re wrong, but it seems much less relevant to what I can contribute (or generally want to engage with) than the fact that you’ve posted that comment and people have upvoted it.
I don’t understand how this can happen on the EA Forum. Why would anyone believing in this and wanting to do good promote this?
If anyone here does believe in ideas that have caused a great amount of harm and will cause more if spread, they should not spread them. If that’s not the specific arguments that you think might be better and should be improved in such and such way but the views that you’re arguing about, don’t! If you want to do good, why would you ever, in our world, spread these views? If the impact of spreading these views is more tragedies happening, more suffering, and more people dying early, please consider these views an infohazard and don’t even talk about them unless you’re absolutely sure your views are not going to spread to people who’ll become more intolerant- or more violent.
If you, as a rationalist, came up with a Basilisk that you thought actually works, thinking that it’s the truth that it works should be a really strong reason not to post it or talk about it, ever.
The feeling of successfully persuading people (or even just engaging in interesting arguments), as good as it might be, isn’t worth a single tragedy that will result from spreading this kind of ideas. Please think about the impact of your words. If people persuaded by what you say might do harm, don’t.
One day, if the kindest of rationalists do solve alignment and enough time passes for humanity to become educated and caring, the AI will tell us what the truth is without a chance of it doing any harm. If you’re right, you’ll be able to say, “I was right all along, and all these woke people were not, and my epistemology was awesome”. Before then, please, if anyone might believe you, don’t tell them what you consider to be the truth.
But can you be trusted to actually think that, given what you say about utility of public admission of opinions in question? For an external observer, it’s a coin toss. And the same for the entirety of your reasoning. As an aside, I’d be terrified of a person who can willfully come to believe – or go through the motions of believing – what he or she believes to be morally prudent but epistemically wrong. Who knows what else can get embedded in one’s mind in this manner.
I don’t understand how this can happen on the EA Forum. Why would anyone believing in this and wanting to do good promote this?
Well, consider that, as it tends to happen in debates, people on the other side may be as perfectly sure about you being misguided and promoting harmful beliefs as you are about them; and that your proud obliviousness with regard to their rationale doesn’t do your attempt at persuasion any more good than your unwillingness to debate the object level does.
Consider, further, that your entire model of this problem space really could be wrong and founded on entirely dishonest indoctrination, both about the scholarly object level and about social dynamics and relative effects of different beliefs.
Finally, consider that some people just have a very strong aversion to the idea that a third party can have the moral and intellectual authority to tell them which thoughts are infohazards. If nothing else, that could help you understand how this can happen.
If you want to do good, why would you ever, in our world, spread these views?
Personally – because I do, in fact, believe that you are profoundly wrong, that even historically these views did not contribute to much harm (despite much misinformation concocted by partisans: policies we know to be harmful are attributable to different systems of views); that, in general, any thesis about systematic relation in the pattern {views I don’t like}=>{atrocities} is highly suspect and should be scrutinized (e.g. with theists who attribute Stalin’s brutality to atheism, or derive all of morality from their particular religion); and that my views offer a reliable way to reduce the amount of suffering humans are subjected to, in many ways from optimizing allocation of funds to unlocking advances in medical and educational research to mitigating slander and gaslighting heaped upon hundreds of millions of innocent people.
Crucially, because I believe that, all that medium-term cost-benefit analysis aside, the process of maintaining views you assume are beneficial constitutes an X-risk (actually a family of different X-risks, in Bostrom’s own classification), by comprehensively corrupting the institution of science and many other institutions. In other words: I think there is no plausible scenario where we achieve substantially more human flourishing in a hundred years – or ever – while deluding ourselves about the blank slate; that it’s you who is infecting others with the “Basilisk” thought virus. And that, say, arguments about the terrible history of some tens of thousands of people whom Americans have tortured under the banner of eugenics – after abusing and murdering millions of people whilst being first ignorant, then in denial about natural selection – miss the point entirely, both the point of effective altruism and of rational debate.
If the impact of spreading these views is more tragedies happening, more suffering, and more people dying early, please consider these views an infohazard and don’t even talk about them unless you’re absolutely sure your views are not going to spread to people who’ll become more intolerant- or more violent.
This is an impossible standard and you probably know it. Risks of a given strategy must be assessed in the context of the full universe of its alternatives; else the party that gets to cherrypick which risks are worth bringing up can insist on arbitrary measures. By the way, I could provide nontrivial evidence that your views have contributed to making a great number of people more intolerant and more violent, and have caused thousands of excess deaths over the last three years; but, unlike your wholly hypothetical fearmongering, it’s likely to get me banned.
Indeed, I could ask in the same spirit: what makes people upvote you? If your logic of cherrypicking risks and demonizing comparative debate is sound, then why don’t they just disregard GiveWell and donate all of their savings to the first local pet shelter that gets to pester them with heart-rending imagery of suffering puppies? Maybe they like puppies to suffer?! This is not just manipulation: rising above such manipulation is the whole conceit of this movement, yet you commit it freely and to popular applause.
To make me or anyone like me change my mind, strong and honest empirical and consequentialist arguments addressing these points are required. But that’s exactly what you say is “much less relevant” than just demanding compliance. Well. I beg to differ.
For my part, I do not particularly hope to persuade you or anyone here, and guidelines say we should strive to limit ourselves to explaining the issue. Honestly it’s just interesting at this point, can you contemplate the idea of being wrong, not just about “HBD” but about its consequences, or are you the definition of a mindkilled fanatic who can’t take a detached view at his own sermon and see that it’s heavy on affirmation, light on evidence?
Adding on to this with regards to IQ in particular, I recommend this article and it’s followup by academic intelligence researchers debunking misconceptions about their field. To sum up some of their points:
IQ test scores are significantly affected by socio-economic and other environmental factors, to the point where one study found adoption from a poor family to a rich one causes a 12-18 point jump in IQ score.
The average IQ of the whole populace jumped 18 points in 50 years due to the Flynn effect.
The gap in test scores between races has been dropping for decades, including a 5 point drop in the IQ test score gap over 30 years.
With the above points in mind, the remaining IQ test score gap of 9.5 points does not seem particularly large, and does not seem to require any genetic explanation.
I don’t think one of the claims, that “Twin studies are flawed in methodology. Twins, even identical twins, simply do not have exactly the same DNA”, is true. As I see, it is not supported by the link and the study.
The difference of 5.2 out of 6 billion letters that identical twins have on average is not something that makes their DNA distinct enough to make the correlations between being identical tweens or not and having something in common more often to be automatically invalid.
One of the people involved in the study is cited: “Such genomic differences between identical twins are still very rare. I doubt these differences will have appreciable contribution to phenotypic [or observable] differences in twin studies.”
Twin studies being something we should be able to rely on seems like a part of the current scientific view, and some EA decisions might take such studies into consideration.
I think it’s important not to compromise our intellectual integrity even when we debunk foundations for awful and obviously wrong beliefs that are responsible for so much unfairness and suffering that exist in our world and for so many deaths.
I think if the community uses words that are persuasive but don’t contain actually good evidence, then even if we’re arguing for the truth that’s important and impactful to spread, in the long-term, this might lead to people putting less trust in any of our words arguing for the truth and more people believing something harmful and untrue. And on the internet, there are a lot of words containing bad arguments for the truth because it’s easy for people to be in the mode of finding persuasive arguments, which don’t necessarily have to be actually good evidence.
I think it’s really important for the EA community to be epistemically honest and talk about the actual reasons we have for believing something, instead of trying to find the most persuasive list of reasons for believing in what we believe in and just copying it without verifying that all the reasons are good and should update people in the claimed direction.
These are two separate links for two separate claims. ‘Twin studies are flawed in methodology.’ and ‘Twins, even identical twins, simply do not have exactly the same DNA.’, both of which are true. The confidence in the proposed HBD conclusions is simply not warranted by the evidence.
Oops! Sorry, I only discovered the second link; but before writing my comment, I looked up the first myself.
I’m not a biologist and will probably defer to any biologist entering this thread and commenting on the twin studies.
Twins (mostly, as the linked study shows) do not have exactly the same DNA. But it doesn’t seem to be relevant. The relevant assumption is that there’s almost no difference between the DNAs of “identical” twins and a large difference between the DNAs of non-identical reared-together twins, which is true despite a couple of random mutations per 6 billion letters.
The next two linked articles are paywalled. Is there somewhere to read them?
The third is a review of a short book, available after a sign-up, and it says that “some studies on twins are good, some bad”, and the author feels, but “doesn’t actually know” that the reviewed one is good. The reviewed book performed a study on twins and noticed there isn’t much of a difference between the correlation of the similarity of many personality traits with whether people are identical twins, and concluded that, since you’d expect to see a difference if the traits have different degree of heritability, many personality traits are results of the environment.
How is this an evidence that twin studies are flawed and shouldn’t be used? If that’s a correct study, it’s just evidence that personality traits are mostly formed by environment (which is something I already believe and have believed for the most of my life), but, e.g., why would this be relevant for a discussion of whether or not some disease has a genetic component to it, when a twin study shows that there is?
It’s important to carefully compare the numbers; but obviously there are things that identical twins have in common more often then non-identical twins, because these things are heritable at to larger or lesser degree; like hair color or height.
Of course, any study makes some underrepresentation of humanity. But if your study is about the degree of heredity of something and not about twins, why would this matter? If there’s a difference between adopted identical and non-identical twins that’s better explained by genetics (e.g., non-identical twins would have a different height more often), why does it matter how well they represent twins in general? Unless you’re studying how likely people are to be adopted, I don’t understand the claim.
The last link is paywalled, but again, why would this affect the difference between identical twins and non-identical twins? Until a year ago, I kept secret that I’m bi and would’ve kept it secret from scientists; but I don’t think this kind of thing affects conclusions you’d make if identical twins answered identically to some question more often than non-identical twins (e.g., imagine a society where people with green eyes are persecuted and a lot of them use contact lenses. Some would still say the truth, in confidence, to scientists; and the number of identical twins telling the same answer would be greater than the amount of non-identical twins telling the same answer, and the scientists will correctly infer this to be evidence for the heritability of eye color, even though a lot of twins would lie about their eye color).
So while it’s possible to just compare full DNAs and account for lots of different factors (all sorts of various environmental conditions that might be different between the subjects of the study) to find out whether DNA correlates with eye color, it’s much easier to do a twin study, and a strong correlation there will be a strong evidence
It’s fine. Studies don’t just use identical twins but twins in general. You are equating my two claims and attacking claims that I haven’t even made, I never talked about “whether or not some disease has a genetic component to it, when a twin study shows that there is?”. I made a claim that twins, even identical twins, don’t share exactly the same DNA and provided a link to an article that gave more information, and I made a second claim that twin studies were flawed and provided that claim with a link to an article with more information about that. All this stuff about that it can’t help us find diseases or that twin studies “shouldn’t be used” are claims I never made.
EDIT:
I’m not a biologist and will probably defer to any biologist entering this thread
For the record my study has some biostatistics, but it isn’t my strongest field and I’m mostly leaning on stuff my professors have explained:
I will also probably defer to a biologist/biostatistician.
As a different perspective to your list, I’d like to reference this thread of 25 threads, which provides extensive research in the opposite direction. Like you, I do not claim that this is all correct (I’m not an expert on this topic), but the evidence is certainly much less clear-cut than one might think from just reading the pieces you provided.
Given my priors and respect for my leisure time I’m not going to read those giant threads. I won’t downvote you since I haven’t actually read it, but let me ask you a related question:
Do you think that out of the billions of possible correlations in the social sciences, the best use of our finite time on earth is to study this one? The incredibly flawed measure of ‘low iq’ is correlated with the arbitrary socially-contingent western category of ‘black people’ (almost certainly because of environmental factors). But there are millions of things correlated with the western category of ‘black people’ and there are millions of things correlated with ‘iq’. Furthermore, there are so many more variables to study that are less flawed and less arbitrary, why should we focus on the one correlation out of billions that racist people –who want to make the world worse for out fellow human beings– want to us to talk about?
I agree with basically everything you say here, but I also think it’s a bit unfair to point this out in the context of Kaspar Brandner sharing a lot of links after you did the same thing first (sharing a lot of links). :)
In any case, I think
not discussing the issue >> discussing the issue >> discussing the issue with flawed claims.
(And I think we’re all in trouble as a society because, unfortunately, people disagree about what the flawed claims are and we get sucked into the discussion kind of against our will because flawed claims can feel triggering.)
but I also think it’s a bit unfair to point this out in the context of Kaspar Brandner sharing a lot of links after you did the same thing first
Yeah that’s fair. I mean I did give summaries, but it’s still fair. If I could go back in time I would’ve posted that comment first and I would’ve tried to explain my emotions/reasoning process to the HBDers on this forum more.
I would have said: I get the allure of taboo studies. I want to be a moral philosopher, but moral philosophers are very smart and they don’t get a lot of funding. So even if I work very very hard, I probably won’t get to be one. I need a way to stand out, to make people notice I would be a good researcher… oh what’s this? Everyone is avoiding these taboo studies. So researching them makes me both stand out and makes me a comparatively high quality researcher since almost no one is competing with me.
It’s competition/capitalism/moloch that is driving me towards these subjects and even knowing this doesn’t make the allure go away. But ultimately I care about people more, and there are often good reasons these taboo’s were put in place. Perhaps the readers of this comment feel the same way. I empathize. The smart thing to have done was unpack these mental prioritizations immediately instead of grabbing my research. But I didn’t think of it, probably because I wanted to show that I could be a good researcher. Moloch got me. Please don’t spend your limited time on this subject, please don’t let moloch get you too.
Writing on such topics does the opposite of favoring your academic career. It is rather a form of career suicide, since you will likely get cancelled and ostracized. The topic is extremely taboo, as we can see with the reaction to Bostrom’s old email. He didn’t even support hereditarianism about IQ gaps, he just said they exist, which even environmentalists accept!
And with good reason, out of the billions of possible correlations to talk about this is one of the very few that will help racists.
Writing on such topics does the opposite of favoring your academic career
True, but most people can’t cut it in academia and if one fancies themselves a researcher this path will allow you to continue to keep doing that without a lot of intellectual competition. Plus you can still get funding from shady organizations like the Pioneer Fund (I call them shady because they funded the distribution of ‘Erbkrank’-a Nazi propaganda film about eugenics- as one of their first projects and because they have ties to white supremacists groups, so their impartiality is suspect)
To be clear, I’m not saying studying this question is more important than anything else, just that research on it should not be suppressed, whatever the truth may be. This point was perhaps best put in the conclusion of this great paper on the topic:
The strategy – advocated by some influential scholars – of stigmatizing, suppressing, or downplaying evidence in favor of hereditarianism about group differences has been tried and has not worked. Research on this topic has been done and the results are widely available. Major psychology journals continue to publish work that deals openly with group differences (though researchers still debate about the relative contribution of genes and environment, and the question has not been settled definitively). Any measures that would be effective in preventing further work, such as those advocated by Kourany (2016), would have to be so severe that they would only attract even more attention to the findings they aimed to suppress. Science will carry on, and these questions will be answered. We should prepare in advance for the possibility that the genes underlying intelligence differences will not be distributed identically among ethnic groups. Failure to do this will only create a vacuum for “cranks rather than scientists” to opine on the nature and consequences of group differences (Anomaly, 2017, p. 293). Reich (2018) warns that if scientists “willfully abstain from laying out a rational framework for discussing human differences, [they] will leave a vacuum that will be filled by pseudoscience” (p. 258).
This paper has argued that the usual utilitarian reasons given for restricting intelligence research are not convincing and, in fact, there are strong reasons, both utilitarian and non-utilitarian, to favor free inquiry. For philosophers specifically, there is an additional consideration. For decades, the contribution of philosophers to this debate has consisted mostly in providing alternative explanations for evidence seeming to support hereditarianism about race differences (see Sesardic, 2000, 2005), and advocating various kinds of restriction and censorship (see Cofnas, 2016). This may be because hereditarianism is controversial, and philosophers are strongly disincentivized from pursuing lines of argument that lead to truly controversial conclusions. Testifying to how serious this problem is, Jeff McMahan, Francesca Minerva, and Peter Singer recently founded the Journal of Controversial Ideas, which will allow scholars to publish pseudonymously. Singer (2017) commented that “it’s unfortunate that such a journal should ever be considered necessary to enable controversial ideas to be published, but perhaps we have got to the point where it is.” It is not clear what kind of controversial ideas Singer had in mind, and the journal has not yet released its first issue, but it is hard to find a more controversial idea than hereditarianism about race differences in intelligence.
There is a danger for the philosophical community in putting our credibility on the line over the claim that race differences are entirely environmental. If work on genetics and neuroscience within the next decade produces convincing evidence that differences in measured intelligence among groups have a significant genetic component, there will be no way to conceal this information. The hereditarian explanation will have to be accepted, and people will know that philosophers were on the wrong side of the issue both scientifically and morally: scientifically, because we are supposed to be careful, disinterested commentators on scientific controversies, not activists supporting only the politically popular side; morally, because we did not help lay the groundwork for responding in a moral way to these facts that we should have known might be coming.
Given my priors and respect for my leisure time I’m not going to read those giant threads. I won’t downvote you since I haven’t actually read it, but let me ask you a related question:
Do you think that out of the billions of possible correlations in the social sciences, the best use of our finite time on earth is to study this one?
The incredibly flawed measure of ‘low iq’ is correlated with the arbitrary socially-contingent western category of ‘black people’ (almost certainly because of environmental factors). But there are millions of things correlated with the western category of ‘black people’ and there are millions of things correlated with ‘iq’.
Also, there are so many more variables to study that are less flawed and less arbitrary, why should we focus on the one correlation out of billions that racist people (who want to make the world worse for out fellow human beings) want to us to talk about?
IMO, I agree with the idea that EA shouldn’t invest anything in studying this, though I took a different path.
I think IQ differences are real and they matter.
However, I think the conclusion that HBD and far-righters/neo-nazis wants us to reach is pretty incorrect, given massive issues with both evidence bases and motivated reasoning/privileging the hypothesis.
A pretty large fraction of engaged EAs believe in HBD. Its quite common the deeper you go into the community.
Okay, if there’s anyone here who actually believes in HBD, here’s a couple reasons why you shouldn’t:
Human biodiversity is actually pretty low. Homo sapiens has been through a number of bottlenecks.
Human migrations over the last thousand years have been such that literally everyone on Earth is a descendant of literally everyone that lived 7000 years ago whose offspring didn’t die out. This is known as the Identical Ancestors Point.
Africans have more genetic diversity than literally every other ethnicity on earth taken together, so any classification that separates “Africans” from other groups is going to be suspect.
Race isn’t a valid construct, genetically speaking. It’s not well defined. Most of the definitions are based on self reports or continents of origin, when we know what is considered “black” in the US may not be so in, say, Brazil, or that many people from Africa can very well be considered “white”.
Intelligence is not well defined. There’s no single definition of intelligence on which people from different fields can agree.
IQ has a number of flaws. It is by definition Gaussian without having appeared empirically first and the g construct itself has almost certainly no neurological basis and is purely an artifact of factor analysis.
Twin studies are flawed in methodology. Twins, even identical twins, simply do not have exactly the same DNA.
Evolution isn’t just mutations and natural selection. Not every trait is an adaptation.
Heritability does not imply genetic determinism. Many things are heritable and do not involve genes. These include epigenetic mechanisms, microbiota, or even environmental stress on germinal cells.
We don’t mate randomly, which is an assumption in many genetics studies.
HBD is not generally accepted in academia.
Many public HBD figures have been found guilty of fraud. Cyril Burt would literally forge results, while Lynn would take the average of two neighboring countries’ IQ in order to derive “data” from a country’s unknown national IQ.
Special thanks to these threads for compiling most of the information
Now you might want to attack one of these (and feel free to send me a message), but even if you’re right, that would still leave more than enough reasons to stay away from HBD.
This list is a good example of the sort of arguments that look persuasive to those already opposed to HBD, but can push people on the fence towards accepting it, so it may be net-negative from your perspective. This is what has happened to me, and I’ll elaborate on why – so that you may rethink your approach, if nothing else.
Disclaimer: I am a non-Western person with few traits worth mentioning. I identify with the rationalist tradition as established on LW, feel sympathy for the ideal of effective altruism, respect Bostrom despite some disagreements, have donated to GiveWell charities on EA advice, but I have not participated more directly. Seeing the drama, people expressing disappointment and threatening to leave the community, and the volume of meta-discussion, I feel like clarifying a few details that may be hard to notice from within your current culture, and hopefully helping you mend the fracture that is currently getting filled with the race-iq stuff.
All else being equal, people who hang around such communities prefer consistent models (indeed, utilitarianism itself is a radical solution to inconsistencies in other ethical theories). This discourse is suffused with intellectual inconsistency, on many levels of varying contentiousness.
On the faint level of moral intuitions, there’s the strange beeline from the poorly supported prior that normalization of beliefs like Bostrom’s will lead to bad effects like discrimination, to the consequentialist decision against entertaining them. It is not clear that Bostrom’s beliefs are harmful in this way, or more likely to encourage a net increase in discrimination than their negation. Arguments from historical precedent have big problems with them: they do not address the direction of causality, or the fact that different cultures can have different reactions to the same information. As it is not considered normal in the modern culture to equate moral worth and ability for individuals of any group, it can be expected that the same will hold should the difference in ability between groups be acknowledged. Arguments from personal distress of users are valid points with regard to community health, but obviously (I hope) incommensurate with the question of global utility, and do not directly weigh on it. So the consequentialist case for not taking Bostrom’s belief in good faith is already suspect.
Perhaps the most obvious level is that specific failings Bostrom is credibly accused of (racist attitude, belief in the racial IQ difference, belief in the validity of IQ measurement) do not depend on HBD. (He has done himself no favors by bringing up eugenics). So it’s bizarre to see many people denounce his beliefs in toto, but support this denunciation with environmentalist explanations of the IQ gap – in effect, conceding the specific factual claim in Bostrom’s old email, or at least demonstrating that it is not beyond the pale by their own standard. To be clear: it is not in doubt that the IQ gap between Black and White Americans exists; and that it is as predictive of outcomes associated with cognitive capacity as IQ measurement is (which is to say, highly predictive – and this, too, is mainstream consensus). People who act indignant about such statements send a huge red flag, demonstrating either general unwillingness to educate themselves or irrational ideological bias on this specific matter. People who bring up irrelevant anti-HBD talking points demonstrate confused reasoning.
Less obviously, the problem is portraying this as an open-and-shut case – a portrayal which doesn’t really survive scrutiny. I don’t know how to put this nicely, but what your list most reminds me of is polemics of sophisticated Creationists in the heyday of New Atheism. It’s a mix of true but irrelevant, misleadingly phrased, blatantly misinterpreting and patently false claims. Instrumentally they are gotchas; structurally, opening moves aimed at people who are not familiar with the debate and are not aware that all those issues had long been answered, and the debate is incredibly mature. Of course, in all such debates both sides can assert that they’ve solved every vulnerability, and this forum isn’t some HBD Central. So I won’t compete in citations, and will just address things a total layman, provided he’s minimally erudite, napkin-numerate, capable of critical thought and aware of basic logical fallacies, could spot, if he were so inclined. You way “Now you might want to attack one of these (and feel free to send me a message), but even if you’re right, that would still leave more than enough reasons to stay away from HBD.” What if we go through every one of these?
Human biodiversity is actually pretty low. Homo sapiens has been through a number of bottlenecks. – maybe true but vacuous. “Pretty” low relative to what baseline? How would we even tell – do we have anything like IQ for other species? Does this genetic fact establish some prior for the magnitude in differences in measurable phenotypic traits between groups? What about individuals? What we do know that people with a priori negligible “biodiversity” – as in, children in ethnically endogamous marriages, even in isolated villages – routinely have large differences in all traits of interest. So how much diversity is needed, really, to introduce some measurable population-level divergence? Likewise for the point about bottlenecks, what of it? Should our layman just conclude that this is an authoritative-sounding technical term?
Human migrations over the last thousand years have been such that literally everyone on Earth is a descendant of literally everyone that lived 7000 years ago whose offspring didn’t die out. This is known as the Identical Ancestors Point. – grossly misleading/false, and doesn’t pass basic sanity check. Is every single unadmixed Indigenous Australian really a descendant of “literally everyone” 7000 years ago, same as every single Han Chinese? But, looking it up, National Geographic says that “Aboriginal Australians are all related to a common ancestor who was a member of a distinct population that emerged on the mainland about 50,000 years ago”, which implies people of other populations are not all related to him. Aha, here’s where your figure comes from: “Rohde, Olson and Chang showed through simulations that, given the false assumption of random mate choice without geographic barriers, the Identical Ancestors Point for all humans would be surprisingly recent, on the order of 5,000-15,000 years ago.” But it is indeed false, there were barriers for the entire history of our species, such as oceans; and how do migrations of the last millenium negate it? More importantly, it’s a quantitative issue. Your link goes on to say: “Thus, even though the Norwegian and Japanese person share the same set of ancestors, these ancestors appear in their family tree in dramatically different proportions. A Japanese person in 5000 BC with present-day descendants will likely appear trillions of times in a modern-day Japanese person’s family tree, but might appear only one time in a Norwegian person’s family tree.” Seeing as every specimen can have novel genetic variants, this should allow for arbitrary magnitude of divergence, no?
Africans have more genetic diversity than literally every other ethnicity on earth taken together, so any classification that separates “Africans” from other groups is going to be suspect. – misleading. The money quote is: “Tishkoff and her colleagues studied DNA markers from around the planet, identifying 14 “ancestral clusters” for all of humanity. Nine of those clusters are in Africa. “You’re seeing more diversity in one continent than across the globe,” Tishkoff said.” Okay, let’s assume that those 9 clusters are meaningfully different (as are the other 5). When people talk of “Africans”, in practice, whom do they refer to? Looking it up,
4. Race isn’t a valid construct, genetically speaking. It’s not well defined”. – but aren’t we already talking of genomic ancestry? So this is a true but irrelevant objection. Now, people are of course free to believe that conventional self-reported “races”, which are, as is often correctly said, social constructs, do not correspond to continental-level ancestry – although noisily in many cases. I think this is pretty absurd on its face, but anyway, Googling tells us “In mothers self-identified as Black and White, the imputed ancestry proportions were 77.6% African and 75.1% European respectively” in a “diverse” NYC sample, and I’d expect less cosmopolitan groups to show higher figures. However unfit race is for purposes of cutting-edge research, in the aggregate data it is robustly aligned with ancestry, which is well-defined.
5. Intelligence is not well defined. There’s no single definition of intelligence on which people from different fields can agree. – blatantly misinterpreting. The cited paper states: ”...Nevertheless, some definitions are clearly more concise, precise and general than others. Furthermore, it is clear that many of the definitions listed above are strongly related to each other and share many common features” and goes on to propose a unified definition: “Intelligence measures an agent’s ability to achieve goals in a wide range of environments.” Features such as the ability to learn and adapt, or to understand, are implicit in the above definition as these capacities enable an agent to succeed in a wide range of environments. Also it is not clear why we’d even need people from different fields (in this case, psychology and AI research!) to agree on a definition of intelligence to have a useful measurement of human smarts. And this is what has happened with IQ:
6. IQ has a number of flaws. It is by definition Gaussian without having appeared empirically first and the g construct itself has almost certainly no neurological basis and is purely an artifact of factor analysis. – this is just some Gish Gallop. To begin with, I don’t see your link supporting your summarization – except the vague “number of flaws”. If I may, where have you taken this list from? In any case, anything but God has a number of flaws; your link says that “According to Weiten, “IQ tests are valid measures of the kind of intelligence necessary to do well in academic work.”″ and “clinical psychologists generally regard IQ scores as having sufficient statistical validity for many clinical purposes”. It doesn’t seem like there’s any scientific objection as to the validity of IQ as a measurement of what’s casually called smarts and understood to be smarts in the context of this discussion – even though there are weird attempts to drown this fact in caveats. Why is the part about assumed Gaussian even relevant? What would it mean for g to have a neurological basis, and why would that matter in the discussion of HBD? …And the part about g being “purely an artifact of factor analysis” is plain false, far as I can tell. It comes from Cosma Shalizi’s essay that misstates the reason for the existence of positive manifold. “If I take any group of variables which are positively correlated, there will, as a matter of algebraic necessity, be a single dominant general factor… Since intelligence tests are made to correlate with each other, it follows trivially that there must appear to be a general factor of intelligence.” This is just a lie: a great deal of effort has been devoted to making cognitive tests comprehensive and diverse assessments of ability, but positive correlations pop out on their own, even in research informed by Shalizi’s assumptions, e.g. “The WJ-R was developed based on the idea that the g factor is a statistical artifact with no psychological relevance. Nevertheless, all of its subtests are intercorrelated and, when factor analyzed, it reveals a general factor that is no less prominent than those of more traditional IQ tests”. And ”...All 861 correlations are positive. Subtests of each IQ battery correlate positively not only with each other but also with the subtests of the other IQ batteries. This is, of course, something that the developers of the three different batteries could not have planned – and even if they could have, they would not have had any reason to do so, given their different theoretical presuppositions.”
7. Twin studies are flawed in methodology. Twins, even identical twins, simply do not have exactly the same DNA. – again, misinterpreting; there are flaws but the method is not summarily “flawed” just because a section about flaws exists. The first link is a list of objections but in no way does it show or argue that they are decisive, or even apply at all to current methods (there are “responses to critiques” subsections). The second is apparently irrelevant, and was already addressed by another user.
8. Evolution isn’t just mutations and natural selection. Not every trait is an adaptation. (a link to Wiki on “Evolution – Evolutionary processes”) – …okay but how does this even support your case? I’m honestly unsure what the idea here is. Taken literally, your summary suggests that evolution can produce maladaptive changes, so we cannot assume that all (or any) populations will be maximally fit (for their environment). This is a pro-eugenicist take, if anything. Whereas the page itself discusses mechanisms of change in allele frequency and does not have any clear impact on the validity of HBD one way or another.
9. Heritability does not imply genetic determinism. Many things are heritable and do not involve genes. These include epigenetic mechanisms, microbiota, or even environmental stress on germinal cells. – irrelevant/false. The link is to “Heritability – Controversies” with some nitpicks of unclear truth value. The second is a general overview of possible issues with heritability estimates. It does not weigh in on HBD and accepts the premise of variable genetic contributions to human intelligence: As a case in point, consider that both genes and environment have the potential to influence intelligence. Heritability could increase if genetic variation increases, causing individuals to show more phenotypic variation, like showing different levels of intelligence. On the other hand, heritability might also increase if the environmental variation decreases, causing individuals to show less phenotypic variation. This says, concretely, that in more equal environments we will observe more true genetic effects on variation in intelligence, so whatever differences in genetic effects on this trait there are between groups, they will become more pronounced. By the way this is terrible for the anti-HBD position because it means that the state of perfect environmental equality – one could say equality of opportunity – will collapse into genetic determinism (modulo random noise). Your own idea seems to be that non-genetic mechanisms of apparent heritability can be interrupted by a positive environmental intervention. What share of “heritable” variance can it explain, at a maximum? Like, concretely, to what extent do you think the racial IQ gap is explained by microbiota, epigenetic mechanisms and environmental stress on germinal cells? Those are all quantifiable and falsifiable claims, but you just gesture at them. At this point, a dedicated layman looks it up and sees that they can explain very little indeed.
10. We don’t mate randomly, which is an assumption in many genetics studies. – irrelevant applause lights, “genetics bad”. Which studies, and does this matter for HBD? I’ve watched the video; it discusses interactions between psychiatric disorders and such, and states that genetic correlations between traits may be inflated by assortative mating (i.e. people high in trait X marry people high in trait Y). Genetic correlation “is defined as the proportion of the heritability that is shared between two traits divided by the square root of the product of the heritability for each trait”. What is meant here, concretely? Ancestry is not really a “heritable trait”, is it? And race is just a category, plus a bad proxy for ancestry, as far as HBD is concerned.
11. HBD is not generally accepted in academia. – this is just an appeal to authority, plus misleading. It’s a single highly technical paper by some Kevin Bird, “Department of Horticulture Michigan State University”, can it be considered an authoritative source on what academia thinks? And from the abstract, it attacks a very strong form of HBD reasoning, using data that cannot plausibly be conclusive: Evidence for selection was evaluated using an excess variance test. Education associated variants were further evaluated for signals of selection by testing for excess genetic differentiation (Fst). Does it strike you as plausible that we know enough about “education associated variants” to impute effects of prehistoric selection on intelligence? This ought to mean that the science of genetics of intelligence is vastly more mature than people think, than you suggest, too, and that within-group intelligence heritability is understood really well! Why hasn’t this made the news yet? (And how does this address obvious low-tech HBD arguments, such as admixture studies and adoption studies?)
12. Many public HBD figures have been found guilty of fraud. Cyril Burt would literally forge results, while Lynn would take the average of two neighboring countries’ IQ in order to derive “data” from a country’s unknown national IQ. – That’s an isolated demand for rigor. What field doesn’t commit fraud? Were public anti-HBD figures never found guilty of fraud? Is the fraud rate different enough to affect our priors? And your link does not show that Burt’s forgery was positively proven, but it admits that figures of heritability arrived at by independent researchers do not differ from Burt’s, so why should we care? Assuming that a layman could track it down from here, I’ll allow myself to quote Richard Haier (The Neuroscience of Intelligence, Cambridge University press, 2017): Subsequent twin studies done by different investigators around the world with large samples arrive at an average value for the correlation of intelligence scores among identical twins raised apart of .75 (Plomin & Petrill, 1997). Burt’s value was .77. For comparison, based on 19 studies ranging in sample sizes between 26 and 1,300 identical twin pairs, the average value for identical twins raised together is about .86 (see Loehlin & Nichols, 1976, table 4.10, p. 39)… Thus, the .771 “fraud” ends with recognition of overwhelming data from independent researchers that are fully consistent with Burt’s analyses, flawed as they may have been. Any single study, or any one researcher, can be flawed, but the basic conclusion that genes play an important role in intelligence is consistently supported by data from numerous studies of twins, adoptees, and adopted twins. This is an excellent example of looking at the weight of evidence (recall my three laws from the Preface: no story is simple; no one study is definitive; it takes many years to sort out conflicting and inconsistent findings and establish a weight of evidence). … The weight of evidence summarized in this chapter leaves no reasonable doubt. Only extreme ideologues are still in denial. As for Lynn’s country data, well, the same logic applies. Do we have any more trustworthy data? Does it refute Lynn’s? Then why not just refer to it instead? Please don’t say that it’s not very interesting and nobody has bothered to collect proper measurements, IQ and race (or rather, ethnicity) is literally the most painful question in modern science, and it’s evident from such dramas that a great many researchers are emotionally invested in proving the relationship wrong.
Ultimately, exposure to this sort of content has done for me what it has done for this person:
I want to make it perfectly clear: those question marks in my point-by-point do not actually indicate uncertainty. They could as well have been references to papers. The field really is about as advanced as Bird’s study suggests – only in the direction he disapproves of. But this isn’t the place for it, surely people can go to some edgier venue and ask for receipts. The point I’m trying to make is: you say “Okay, if there’s anyone here who actually believes in HBD, here’s a couple reasons why you shouldn’t.” On an ignorant but moderately skeptical person your little list can, and likely will, have an effect that’s the opposite of what you intend to achieve. To “who actually believes in HBD”, it’s utterly unconvincing. If I may be so blunt, it’s almost as sad as quasi-scientific gotchas of flat earthers.
And this is how all of anti-HBD rhetoric is, in my experience. It crumbles under basic scrutiny, links do not show what they are purported to show, there are simple misunderstandings of what terms mean, there is no coherent epistemology or a single model, there’s suppression of inconvenient evidence, there’s substitution of evidence with confident op-eds in Vox from people who are supposed to be experts (but whose legitimate work doesn’t support their confident claims), there are cascades of internally inconsistent Gish Gallops and other fallacies; worst of all, the reader is assumed to just not be all that bright. It’s a collection of purely reactive objections that might come across as persuasive to like-minded people, but are not battle-tested – and indicate general unwillingness to test one’s beliefs.
I expect very little payoff from this labor. But it would be nice if EAs were to become a little more reserved on this topic, and at least stopped turning off potential recruits with irrefutable displays of irrationality.
84% of surveyed intelligence researchers believe the gaps are at least partially genetic.[1] This statement is not just an appeal to authority, it is also inaccurate.

Why did you reply to MissionCriticalBit when it was I who made that claim? I almost didn’t see it.
Also pointing out that the academics who study this stuff for a living don’t believe in it is not fallacious, but rather a very useful piece of information.
Anyway, I wanted to give the HBDers another shot so I downloaded the survey (can we all agree that paywalls for publicly funded research is bullshit?) and I have two important things to note: genetic gaps is not equivalent to racial gaps, and the survey itself admits it is unrepresentative.
It was an internet survey:
and had a high nonresponse rate:
with respondents who are different than the field as a whole:
which heavily biases the results in favor of your position:
EDIT: To respond to missioncriticalbit below. My comment was about the sentence “HBD is not generally accepted in academia”. The reason I can’t show you a survey that shows you that is the same reason I can’t show you a survey that zoologists don’t believe in unicorns, they don’t engage with it so there is no survey available (even the bad survey by anon rationalist is not about HBD). But I don’t want to make an assertion without citing anything, so what is the best available option? How about an example of a professional biologists with no conflict of interests using publicly available data to create a well received paper that has been seen more than 12000 times that clearly rejects HBD.
Missioncriticalbit just makes assertions without citing anything. The reason I don’t respond and refused to continue to read his reply is not because I am afraid, but because he hadn’t cited anything, didn’t engage with my writings and outright insulted me.
The reason I respond in an edit instead of a reply is because the HBDers have removed half a dozen of my latest comments from the frontpage while taking away a big chunk of my voting-power on this forum. I’m not inclined to give them another way to take away my voting-power, but I don’t want to silence myself, so using the edit button is my workaround.
First, that depends on what you mean by “this stuff”; Bird does not study intelligence nor behavioral genetics for a living, he’s a plant geneticist. Skewed though the survey may be, it’s probably more representative than a single non-expert.
Second, why do you suppose the non-response rate is so high and so skewed? And might it have something in common with your own refusal to continue our conversation on merits of your list?
I suspect that professionals who prefer not to respond, rather than respond in the negative about genetic contributions to the IQ gap, are driven by contradictory impulses: they believe that the evidence doesn’t allow for a confident “100% environmental” response and, being scientists, have problem with outright lying, but they also don’t want to give the impression of supporting socially unapproved beliefs or “validating” the very inquiry into this topic. So they’d rather wash their hands of the whole issue, and allow their less squeamish colleagues to give the impression of moderate consensus in favor of genetic contribution.
Differential response within the survey is again as bad.
The response rate for the survey as a whole was about 20% (265 of 1345), and below 8% (102) for every individual question on which data was published across three papers (on international differences, the Flynn effect, and controversial issues).
Respondents attributed the heritability of U.S. black-white differences in IQ 47% on average to genetic factors. On similar questions about cross-national differences, respondents on average attributed 20% of cognitive differences to genes. On the U.S. question, there were 86 responses, and on the others, there were between 46 and 64 responses.
Steve Sailer’s blog was rated highest for accuracy in reporting on intelligence research—by far, not even in the ballpark of sources that got more ratings (those sources being exactly every mainstream English-language publication that was asked about). It was rated by 26 respondents.
The underlying data isn’t available, but this is all consistent with the (known) existence of a contingent of ISIR conference attendees who are likely to follow Sailer’s blog and share strong, idiosyncratic views on specifically U.S. racial differences in intelligence. The survey is not a credible indicator of expert consensus.
(More cynically, this contingent has a history of going to lengths to make their work appear more mainstream than it is. Overrepresenting them was a predictable outcome of distributing this survey. Heiner Rindermann, the first author on these papers, can hardly have failed to consider that. Of course, what you make of that may hinge on how legitimate you think their work is to begin with. Presumably they would argue that the mainstream goes to lengths to make their work seem fringe.)
Even if you think my reasons failed, why would that push you towards accepting it? HBD is a hypothesis for how the world works, so the burden of proof is on HBD and giving a bad reason not to believe in HBD is not evidence for HBD. To give a very clear example, if someone says ‘I believe in unicorns’, and I say ‘no unicorns do not exist because 1+1=3’ that would fail to be evidence for unicorns not existing, but that does not mean it counts towards evidence for unicorns existing.
Thank you for donating to GiveWell! Unimportant nitpick that has always bothered me: LW has an empiricist tradition, the term ‘rationalist’ is a misnomer.
I wouldn’t say other ethical theories are internally inconsistent. They might have other attributes or conclusions that you think are bad, but the major ethical theories don’t have any inconsistencies as far as I can tell. Do you have an example?On the other hand I do think Eliezer has some inconsistencies in his philosophy, although it’s hard to tell because he’s quite vague, doesn’t always use philosophical terminology (in fact he is very dismissive of the field as a whole) and has a tendency to reinvent the wheel instead (e.g his ‘Requiredism’ is what philosophers would call compatibilism). Now usually I wouldn’t mind it that much, but since philosophy requires such precision of language if you don’t want to talk past each other, I do think this doesn’t work in his favor.
I would like to point out that my comment was not about Bostrom.
I mean even if you don’t know which way the arrow of causality points, that’s still an unnecessarily big risk. It’s not particularly altruistic to make statements that have that big a chance of helping racists. You could also spend your time… not doing that. Also even if you reject arguments from historical precedent there is still the entire field of linguistic racism.
Just because people won’t publicly state it doesn’t mean it doesn’t influence their thinking. Take for example the stereotype of the welfare queen. While not everyone will explicitly state ‘this person has a lower moral worth’ (although some will) the racist stereotyping does lead to black people being harmed both socially and economically. The myth of meritocracy is strong, and people who are seen as unable to ‘pull themselves up by their bootstraps’ are looked down upon.
What global utility? Racists want us to talk about this stuff, there are other correlations that are both on firmer ground, have more global utility and aren’t fulfilling the desires of racists.
If you had read my comments you would’ve seen that I both didn’t respond to Bostrom, did respond to HBD and did support the environmental explantation of the IQ gap.
My comment didn’t deny the existence of an IQ gap and my comment was responding to sapphire who was talking about HBD specifically and so it wasn’t “irrelevant anti-HBD talking point”. If you’re not engaging with what I actually write I’m starting to think that spending hours on this comment wasn’t the best use of my time.
Very civil. It will not surprise you to learn that this does not motivate me to keep reading.
Yeah I’m out.
*I’m going to spend my time on something else now.
This logic is only applicable to contrived scenarios where there is no prior knowledge at all – but you need some worldly knowledge to understand what both these hypotheses are about.
Crucially, there is the zero-sum nature of public debate. People deliberately publicizing reasons to not believe some politically laden hypothesis are not random sources of data found via unbiased search: they are expected to cherrypick damning weaknesses. They are also communicating standards of the intellectual tradition that stands by the opposing hypothesis. A rational layman starts with equal uncertainty about truth values of competing hypotheses, but learning that one side makes use of arguments that are blatantly unconvincing on grounds of mundane common sense can be taken as provisional evidence against their thesis even before increasing object-level certainty: poor epistemology is evidence against ability to discover truth, and low-quality cherrypicked arguments point to a comprehensively weak case. Again, consider beliefs generally known to be kooky, and what they bring to bear on the opposition. Their standard of rigor alone is discrediting to what they believe in.
Moreover, I’ve established that, upon checking, some of your links positively provide evidence in favor of HBD, rather than against – at least by the standard of evidence implicit in the phrasing of the list. Returning again to the Identical Ancestors Point, is presented as an Anti-HBD finding in the first place because it implies a very low prior for genetic divergence of populations, migrations somehow averaging it all out: Human migrations over the last thousand years have been such that literally everyone on Earth is a descendant of literally everyone that lived 7000 years ago whose offspring didn’t die out. (Is this the wrong takeaway? What, then, did you mean to say by adding it?) Looking into the actual paper, we see: …For example, a present-day Norwegian generally owes the majority of his or her ancestry to people living in northern Europe at the IA point, and a very small portion to people living throughout the rest of the world. Furthermore, because DNA is inherited in relatively large segments from ancestors, an individual will receive little or no actual genetic inheritance from the vast majority of the ancestors living at the IA point. Not only does this make the original argument invalid (even in a strong absolute sense – there can be zero common inheritance!) – it directly reinforces the HBD conjecture that long-term (i.e. pre-IAP) divergent local adaptation is relevant to current genetic (and trait) differences.
I agree that this is improper and irritating terminology, because doctrinally, LW asserts its allegiance to empiricism, with all the talk about Bayes-updating on evidence and how rationalists must “win”. But in practice this isn’t so clear-cut: LW is fascinated with armchair thought experiments (that routinely count as evidence to update on), and all the attention devoted to infohazards, Pascal mugging, one-boxing, AI scenarios etc. suggests that they, as a living tradition, are not resilient to speculation the way pure empiricists – say, regular natural scientists – would be. So, not necessarily a misnomer.
They are internally consistent, but I think the point of ethical theory is to clarify the intuitively knowable essence of moral action for purposes of nontrivial decisionmaking, not to assert what morality is and derive an arbitrary decision rule from there. Utilitarianism is often criticized for things like the repugnant conclusion, yet non-utilitarian ethical theories routinely produce more grating outputs, because they fail to capture the most significant part of intuitive ethics, which is mostly about harm reduction under conditions of resource scarcity. They are less consistent with ethics given to us in lived experience, so to speak.
No, the extent of the purported risk matters. You are just falling back on the unsupported prior about cost-benefit ratio because you have preemptively excluded all factors that may change the qualitative conclusion of “not doing that”. To give a specific example: under the assumption that HBD is wrong, we must consider disparate outcomes to be a result of some discrimination and devote resources to alleviate it; but if HBD is actually right, this’d necessarily mean that our costly attempts to help low-performing groups are suboptimal or futile (as in, not effective), and that we will have unfairly attributed blame, harming other groups psychologically and materially. Then there are knock-on effects of harming science: for starters, fears of enabling racists can hold back genomic medicine (and population-specific treatment) by increasing hurdles to data collection and access. We do not have a priori knowledge as to which costs are negligible. On a more meta level, Scott Alexander’s parable comes to mind.
IMO it’s a weak argument because for all the racism, black Americans still report the highest self-esteem of all racial groups; and theories of stereotype threat are apparently unsupported by high-quality data; so it isn’t clear what the odds are that some HBD research or whatever would harm people substantially. But even before that – there are laws against hate speech and discrimination, and they can be strengthened if needed; it seems very suboptimal to focus on not developing neutral knowledge only to deny hateful ideologies rhetorical ammo, instead of dealing with them directly. By the way, cannot racists point to censorshipas sufficient evidence of their correctness, if their intent is to spin available facts to their benefit? Actually, doesn’t this enable them to – convincingly – claim that facts are much worse than they are, that the genomic gap in cognitive ability is bigger than the non-zero gap we’d have found (and, I believe, have partially found) with proper research (which is currently prohibited)? And in any case, you have to put racism-driven harms in the context of costs of pretending that HBD is certainly false – that is, under the assumption that we are “just not doing that” and have no clue whether it is or isn’t true.
As an aside, I am personally puzzled by the strong conviction of many that HBD becoming common knowledge could lead to normalization of racial discrimination. This is a normative, not scientific question. Societies with Social Darwinist values do not need HBD to embrace and exacerbate the status quo of disparate power. Societies with ethnocentric values opportunistically oppose and exploit ethnic outgroups regardless of relative merit. Mainstream modern value system depends on the premise of human rights, not equality of capability. We do not hold that it is normal to oppress individuals who are known to be below average in some morally neutral trait (except maybe for an expansive definition of “oppress” and clinical issues having to do with lack of legal capacity), we have a strong revulsion to identity-based discrimination, and we understand the unreasonableness of treating individuals on the basis of average values.
Uncharitably, in the case of EA, this concern may have to do with the strain (common to EA and LW) of conspiratorial elitism and distrust in the democratic process, and with the unconscious belief that intelligence does define moral worth. That’s …not a very popular belief. I would deeply hate it if my cognitive betters acted like they have greater moral worth than myself, and therefore, to be fair, I cannot deny equal moral worth to people of lower ability. Most people correctly believe that they aren’t brilliant, but they’re not so dull as to not arrive at this logic. There are some contingent factors that complicate the picture, but not fundamentally.
Without getting into the weeds of stereotype scholarship, the extent of claimed harms, and the irrational denial of the role of merit in achievement (reasoning in that wiki page doesn’t even begin to address what would happen in a “proper” meritocratic society after a few generations, because it is premised on genes not contributing to achievement; this is a typical case of an unexamined anti-HBD prior leading to policy errors)… I’ll just say that in my opinion both those issues, insofar as they harm anyone, have to do with beliefs about moral qualities. If “Protestant ethic” is alive and prescribes vilification of people of lower morally neutral ability, then that is a problem in its own right and beyond the scope of this conversation. Luckily, Protestant ethic also encourages treating people on a case by case basis.
Crucially, the search for interventions that actually close the IQ gap. As it stands, we have picked low-hanging fruit like lead exposure, malnutrition, iodine deficiency, parasites and such (in developed nations; I expect EA efforts in Africa to keep delivering on this front), and are left with pursuing dead ends of addressing iniquity like the “food deserts” nonsense, or doubling down on stuff like school spending, that has long ran into diminishing or zero returns and is only popular because to point out its inefficacy means to risk being labeled racist. As Nathan Cofnas argues,
Ironically, Cofnas got in trouble for this. If the suppression starts this far upstream from the object level, how can our priors be trusted?
I sincerely doubt you can prove 1 or 2 (given that your critiques of relevant methodology weren’t persuasive), and it looks like assigning any value to 3, on its own, is pure spite that is best left out of effective altruism. Making racists mad is not, in fact, a positive good, fun as it may be.
Have read some. I explicitly say I’m addressing the state of discourse here, more than just your comment. I respond to you in particular when I quote specific passages. Sorry if that was unclear.
Again, this is not HBD Central, and it is sufficient to establish that there is legitimate uncertainty, so we cannot fall back on the comfortable prior that costs of repudiating HBD are negligible.
Well, I believe that misleading people, and even wasting people’s time on true but irrelevant, misleadingly phrased, blatantly misinterpreting and patently false claims is a form of rudeness that’s extra obnoxious, because it craftily avoids opprobrium one could earn with trivial show of disrespect. It’s not fair to act indignant about an unflattering comparison after doing that. Even so, I’ve made peace with Brandolini’s law, and kept addressing those claims on the object level, to substantiate my “very civil” summary and so that “EAs were to become a little more reserved on this topic, and at least stopped turning off potential recruits with irrefutable displays of irrationality.” To be honest your reaction isn’t wholly unexpected, but I did hope that I’ve been polite enough to merit some tolerance.
OK but please think of your stated desire is to persuade those who happen to believe in HBD to disbelieve it. Obviously you’ve failed in my case, but I maintain that flaming out like that is detrimental even as far as fence-sitters are concerned. I believe I’ve provided sufficient receipts for the purpose of showing how your list is inadequate.
It is really not hard to showboat on this topic, by citing from very clearly argued stuff like this or “authoritative” sources like that review or very technical recent papers or just by gesturing in the general direction of environmentalist rhetoric that is… the way I’ve described, and evident in, e.g., this condemnation of Cofnas, mired in (what I hope is obvious after my initial comment) logical fallacies and half-truths and raw indignation. Or one can just say that if this guy is challenged not by rational and empirical arguments but by being repeatedly called a pseudoscientist and getting a page full of personal attacks on him to the top of search results for his name (a page he responds to with an even pettier page), then he may get a lot of uncomfortable stuff right.
My point is not to showboat but to argue that people who pursue this anti-HBD rhetorical strategy, including you, are probably not succeeding, and are doing the community no favors.
I don’t want to engage with your arguments. I strongly think you’re wrong, but it seems much less relevant to what I can contribute (or generally want to engage with) than the fact that you’ve posted that comment and people have upvoted it.
I don’t understand how this can happen on the EA Forum. Why would anyone believing in this and wanting to do good promote this?
If anyone here does believe in ideas that have caused a great amount of harm and will cause more if spread, they should not spread them. If that’s not the specific arguments that you think might be better and should be improved in such and such way but the views that you’re arguing about, don’t! If you want to do good, why would you ever, in our world, spread these views? If the impact of spreading these views is more tragedies happening, more suffering, and more people dying early, please consider these views an infohazard and don’t even talk about them unless you’re absolutely sure your views are not going to spread to people who’ll become more intolerant- or more violent.
If you, as a rationalist, came up with a Basilisk that you thought actually works, thinking that it’s the truth that it works should be a really strong reason not to post it or talk about it, ever.
The feeling of successfully persuading people (or even just engaging in interesting arguments), as good as it might be, isn’t worth a single tragedy that will result from spreading this kind of ideas. Please think about the impact of your words. If people persuaded by what you say might do harm, don’t.
One day, if the kindest of rationalists do solve alignment and enough time passes for humanity to become educated and caring, the AI will tell us what the truth is without a chance of it doing any harm. If you’re right, you’ll be able to say, “I was right all along, and all these woke people were not, and my epistemology was awesome”. Before then, please, if anyone might believe you, don’t tell them what you consider to be the truth.
But can you be trusted to actually think that, given what you say about utility of public admission of opinions in question? For an external observer, it’s a coin toss. And the same for the entirety of your reasoning. As an aside, I’d be terrified of a person who can willfully come to believe – or go through the motions of believing – what he or she believes to be morally prudent but epistemically wrong. Who knows what else can get embedded in one’s mind in this manner.
Well, consider that, as it tends to happen in debates, people on the other side may be as perfectly sure about you being misguided and promoting harmful beliefs as you are about them; and that your proud obliviousness with regard to their rationale doesn’t do your attempt at persuasion any more good than your unwillingness to debate the object level does.
Consider, further, that your entire model of this problem space really could be wrong and founded on entirely dishonest indoctrination, both about the scholarly object level and about social dynamics and relative effects of different beliefs.
Finally, consider that some people just have a very strong aversion to the idea that a third party can have the moral and intellectual authority to tell them which thoughts are infohazards. If nothing else, that could help you understand how this can happen.
Personally – because I do, in fact, believe that you are profoundly wrong, that even historically these views did not contribute to much harm (despite much misinformation concocted by partisans: policies we know to be harmful are attributable to different systems of views); that, in general, any thesis about systematic relation in the pattern {views I don’t like}=>{atrocities} is highly suspect and should be scrutinized (e.g. with theists who attribute Stalin’s brutality to atheism, or derive all of morality from their particular religion); and that my views offer a reliable way to reduce the amount of suffering humans are subjected to, in many ways from optimizing allocation of funds to unlocking advances in medical and educational research to mitigating slander and gaslighting heaped upon hundreds of millions of innocent people.
Crucially, because I believe that, all that medium-term cost-benefit analysis aside, the process of maintaining views you assume are beneficial constitutes an X-risk (actually a family of different X-risks, in Bostrom’s own classification), by comprehensively corrupting the institution of science and many other institutions. In other words: I think there is no plausible scenario where we achieve substantially more human flourishing in a hundred years – or ever – while deluding ourselves about the blank slate; that it’s you who is infecting others with the “Basilisk” thought virus. And that, say, arguments about the terrible history of some tens of thousands of people whom Americans have tortured under the banner of eugenics – after abusing and murdering millions of people whilst being first ignorant, then in denial about natural selection – miss the point entirely, both the point of effective altruism and of rational debate.
This is an impossible standard and you probably know it. Risks of a given strategy must be assessed in the context of the full universe of its alternatives; else the party that gets to cherrypick which risks are worth bringing up can insist on arbitrary measures. By the way, I could provide nontrivial evidence that your views have contributed to making a great number of people more intolerant and more violent, and have caused thousands of excess deaths over the last three years; but, unlike your wholly hypothetical fearmongering, it’s likely to get me banned.
Indeed, I could ask in the same spirit: what makes people upvote you? If your logic of cherrypicking risks and demonizing comparative debate is sound, then why don’t they just disregard GiveWell and donate all of their savings to the first local pet shelter that gets to pester them with heart-rending imagery of suffering puppies? Maybe they like puppies to suffer?! This is not just manipulation: rising above such manipulation is the whole conceit of this movement, yet you commit it freely and to popular applause.
To make me or anyone like me change my mind, strong and honest empirical and consequentialist arguments addressing these points are required. But that’s exactly what you say is “much less relevant” than just demanding compliance. Well. I beg to differ.
For my part, I do not particularly hope to persuade you or anyone here, and guidelines say we should strive to limit ourselves to explaining the issue. Honestly it’s just interesting at this point, can you contemplate the idea of being wrong, not just about “HBD” but about its consequences, or are you the definition of a mindkilled fanatic who can’t take a detached view at his own sermon and see that it’s heavy on affirmation, light on evidence?
Adding on to this with regards to IQ in particular, I recommend this article and it’s followup by academic intelligence researchers debunking misconceptions about their field. To sum up some of their points:
IQ test scores are significantly affected by socio-economic and other environmental factors, to the point where one study found adoption from a poor family to a rich one causes a 12-18 point jump in IQ score.
The average IQ of the whole populace jumped 18 points in 50 years due to the Flynn effect.
The gap in test scores between races has been dropping for decades, including a 5 point drop in the IQ test score gap over 30 years.
With the above points in mind, the remaining IQ test score gap of 9.5 points does not seem particularly large, and does not seem to require any genetic explanation.
I don’t think one of the claims, that “Twin studies are flawed in methodology. Twins, even identical twins, simply do not have exactly the same DNA”, is true. As I see, it is not supported by the link and the study.
The difference of 5.2 out of 6 billion letters that identical twins have on average is not something that makes their DNA distinct enough to make the correlations between being identical tweens or not and having something in common more often to be automatically invalid.
One of the people involved in the study is cited: “Such genomic differences between identical twins are still very rare. I doubt these differences will have appreciable contribution to phenotypic [or observable] differences in twin studies.”
Twin studies being something we should be able to rely on seems like a part of the current scientific view, and some EA decisions might take such studies into consideration.
I think it’s important not to compromise our intellectual integrity even when we debunk foundations for awful and obviously wrong beliefs that are responsible for so much unfairness and suffering that exist in our world and for so many deaths.
I think if the community uses words that are persuasive but don’t contain actually good evidence, then even if we’re arguing for the truth that’s important and impactful to spread, in the long-term, this might lead to people putting less trust in any of our words arguing for the truth and more people believing something harmful and untrue. And on the internet, there are a lot of words containing bad arguments for the truth because it’s easy for people to be in the mode of finding persuasive arguments, which don’t necessarily have to be actually good evidence.
I think it’s really important for the EA community to be epistemically honest and talk about the actual reasons we have for believing something, instead of trying to find the most persuasive list of reasons for believing in what we believe in and just copying it without verifying that all the reasons are good and should update people in the claimed direction.
These are two separate links for two separate claims. ‘Twin studies are flawed in methodology.’ and ‘Twins, even identical twins, simply do not have exactly the same DNA.’, both of which are true. The confidence in the proposed HBD conclusions is simply not warranted by the evidence.
Many twin studies have the assumption that they share 100% of their DNA (which is false) andthat they share the exact same environment (which is also false). This leads to underestimating environmental factors and underestimating non-genetic biological factors.
Furthermore, separated twin pairs, identical or fraternal, are generally separated by adoption. This makes them unrepresentative of twins as a whole and there can be some issues of undetected behaviors in the case of behaviors that many people keep secret presently or in their earlier lives.
Oops! Sorry, I only discovered the second link; but before writing my comment, I looked up the first myself.
I’m not a biologist and will probably defer to any biologist entering this thread and commenting on the twin studies.
Twins (mostly, as the linked study shows) do not have exactly the same DNA. But it doesn’t seem to be relevant. The relevant assumption is that there’s almost no difference between the DNAs of “identical” twins and a large difference between the DNAs of non-identical reared-together twins, which is true despite a couple of random mutations per 6 billion letters.
The next two linked articles are paywalled. Is there somewhere to read them?
The third is a review of a short book, available after a sign-up, and it says that “some studies on twins are good, some bad”, and the author feels, but “doesn’t actually know” that the reviewed one is good. The reviewed book performed a study on twins and noticed there isn’t much of a difference between the correlation of the similarity of many personality traits with whether people are identical twins, and concluded that, since you’d expect to see a difference if the traits have different degree of heritability, many personality traits are results of the environment.
How is this an evidence that twin studies are flawed and shouldn’t be used? If that’s a correct study, it’s just evidence that personality traits are mostly formed by environment (which is something I already believe and have believed for the most of my life), but, e.g., why would this be relevant for a discussion of whether or not some disease has a genetic component to it, when a twin study shows that there is?
It’s important to carefully compare the numbers; but obviously there are things that identical twins have in common more often then non-identical twins, because these things are heritable at to larger or lesser degree; like hair color or height.
Of course, any study makes some underrepresentation of humanity. But if your study is about the degree of heredity of something and not about twins, why would this matter? If there’s a difference between adopted identical and non-identical twins that’s better explained by genetics (e.g., non-identical twins would have a different height more often), why does it matter how well they represent twins in general? Unless you’re studying how likely people are to be adopted, I don’t understand the claim.
The last link is paywalled, but again, why would this affect the difference between identical twins and non-identical twins? Until a year ago, I kept secret that I’m bi and would’ve kept it secret from scientists; but I don’t think this kind of thing affects conclusions you’d make if identical twins answered identically to some question more often than non-identical twins (e.g., imagine a society where people with green eyes are persecuted and a lot of them use contact lenses. Some would still say the truth, in confidence, to scientists; and the number of identical twins telling the same answer would be greater than the amount of non-identical twins telling the same answer, and the scientists will correctly infer this to be evidence for the heritability of eye color, even though a lot of twins would lie about their eye color).
So while it’s possible to just compare full DNAs and account for lots of different factors (all sorts of various environmental conditions that might be different between the subjects of the study) to find out whether DNA correlates with eye color, it’s much easier to do a twin study, and a strong correlation there will be a strong evidence
It’s fine.
Studies don’t just use identical twins but twins in general. You are equating my two claims and attacking claims that I haven’t even made, I never talked about “whether or not some disease has a genetic component to it, when a twin study shows that there is?”. I made a claim that twins, even identical twins, don’t share exactly the same DNA and provided a link to an article that gave more information, and I made a second claim that twin studies were flawed and provided that claim with a link to an article with more information about that. All this stuff about that it can’t help us find diseases or that twin studies “shouldn’t be used” are claims I never made.
EDIT:
For the record my study has some biostatistics, but it isn’t my strongest field and I’m mostly leaning on stuff my professors have explained:
I will also probably defer to a biologist/biostatistician.
As a different perspective to your list, I’d like to reference this thread of 25 threads, which provides extensive research in the opposite direction. Like you, I do not claim that this is all correct (I’m not an expert on this topic), but the evidence is certainly much less clear-cut than one might think from just reading the pieces you provided.
Given my priors and respect for my leisure time I’m not going to read those giant threads. I won’t downvote you since I haven’t actually read it, but let me ask you a related question:
Do you think that out of the billions of possible correlations in the social sciences, the best use of our finite time on earth is to study this one?
The incredibly flawed measure of ‘low iq’ is correlated with the arbitrary socially-contingent western category of ‘black people’ (almost certainly because of environmental factors). But there are millions of things correlated with the western category of ‘black people’ and there are millions of things correlated with ‘iq’.
Furthermore, there are so many more variables to study that are less flawed and less arbitrary, why should we focus on the one correlation out of billions that racist people –who want to make the world worse for out fellow human beings– want to us to talk about?
I agree with basically everything you say here, but I also think it’s a bit unfair to point this out in the context of Kaspar Brandner sharing a lot of links after you did the same thing first (sharing a lot of links). :)
In any case, I think
not discussing the issue >> discussing the issue >> discussing the issue with flawed claims.
(And I think we’re all in trouble as a society because, unfortunately, people disagree about what the flawed claims are and we get sucked into the discussion kind of against our will because flawed claims can feel triggering.)
Yeah that’s fair. I mean I did give summaries, but it’s still fair. If I could go back in time I would’ve posted that comment first and I would’ve tried to explain my emotions/reasoning process to the HBDers on this forum more.
I would have said: I get the allure of taboo studies. I want to be a moral philosopher, but moral philosophers are very smart and they don’t get a lot of funding. So even if I work very very hard, I probably won’t get to be one. I need a way to stand out, to make people notice I would be a good researcher… oh what’s this? Everyone is avoiding these taboo studies. So researching them makes me both stand out and makes me a comparatively high quality researcher since almost no one is competing with me.
It’s competition/capitalism/moloch that is driving me towards these subjects and even knowing this doesn’t make the allure go away. But ultimately I care about people more, and there are often good reasons these taboo’s were put in place.
Perhaps the readers of this comment feel the same way. I empathize. The smart thing to have done was unpack these mental prioritizations immediately instead of grabbing my research. But I didn’t think of it, probably because I wanted to show that I could be a good researcher. Moloch got me. Please don’t spend your limited time on this subject, please don’t let moloch get you too.
Writing on such topics does the opposite of favoring your academic career. It is rather a form of career suicide, since you will likely get cancelled and ostracized. The topic is extremely taboo, as we can see with the reaction to Bostrom’s old email. He didn’t even support hereditarianism about IQ gaps, he just said they exist, which even environmentalists accept!
And with good reason, out of the billions of possible correlations to talk about this is one of the very few that will help racists.
True, but most people can’t cut it in academia and if one fancies themselves a researcher this path will allow you to continue to keep doing that without a lot of intellectual competition. Plus you can still get funding from shady organizations like the Pioneer Fund (I call them shady because they funded the distribution of ‘Erbkrank’-a Nazi propaganda film about eugenics- as one of their first projects and because they have ties to white supremacists groups, so their impartiality is suspect)
Strong disagree here. See the quote of the paper I posted below.
I don’t fault you for not reading it all, but it is a good resource for looking up specific topics. (I have summarized a few of the points here.) And I don’t think IQ is a flawed measure, since it is an important predictor for many measures of life success. Average national IQ is also fairly strongly correlated with measures of national welfare such as per Capita GDP.
To be clear, I’m not saying studying this question is more important than anything else, just that research on it should not be suppressed, whatever the truth may be. This point was perhaps best put in the conclusion of this great paper on the topic:
IMO, I agree with the idea that EA shouldn’t invest anything in studying this, though I took a different path.
I think IQ differences are real and they matter.
However, I think the conclusion that HBD and far-righters/neo-nazis wants us to reach is pretty incorrect, given massive issues with both evidence bases and motivated reasoning/privileging the hypothesis.
