they don’t discuss (let alone defend) “strong form PTC” theory.
I suppose we simply disagree here. The first quote I cite states “the products need to taste the same or better and cost the same or less.” The next sentence strongly implies that “the market can kick in and take it from there, just shoot us up the S-curve,” with “necessary but not sufficient” relegated to a “quibble.” In conjunction with the Q&A, I think reasonable audience member would infer that your statements mean roughly “if price and taste parity were met, a majority of consumers would soon switch.” Conversely, it’s hard to imagine audience members construing “up the S-curve”, “huge, huge dent” and “change the massive trajectory” to mean, for example, 20% of people switch over two decades.
And in the second case, since we’re at 1% plant-based meat right now and 0% cultivated meat, my statements that “we can have many times the penetration that we have right now if we can get to price and taste parity” and “if you can get to price and taste parity, you can make a huge, huge dent”: 1) don’t mean that nothing else is required; and also 2) don’t mean that we magically reach 50%+.
Can you clarify roughly what number you did intend “many times the penetration” and “huge, huge dent” to refer to here?
It feels curious to me that you continue to claim I believe something that I am telling you explicitly that I don’t believe; you are essentially saying “you believe this and you’re wrong,” and I’m saying “I agree that’s wrong, and I don’t believe it.”
I don’t think you believe this given you’re clearly saying you do not. Instead, as I wrote, “I’d contend that you (and GFI) have prominently promoted and supported the strong PTC hypothesis. Or, at the very least, made statements that reasonable people interpret to support the strong PTC hypothesis.” The situation to me begins to resemble a motte-and-bailey fallacy, with the strong PTC hypothesis as the bailey and the weak as the motte.
With regard to your four specific critiques: I think the overwhelming evidence of the importance of taste and price (including in the three sections from your paper) are a strong response to specific critiques about specific studies. i.e., the overwhelming preponderance of the evidence indicates the importance of taste and price to food choice.
You’re simply reasserting your disagreement and declining to engage the critiques, despite being asked multiple times now (1, 2). In fact, none of the studies you cited address all four of the issues, and studies simply repeating the issues do not make for overwhelming evidence. I don’t follow your argument against “specific critiques about specific studies?” Presumably vague critiques of unspecified studies would be unhelpful. A third time I’d ask, are you able to address these critiques, especially in those studies that predate 2015, when you started claiming price and taste as the most important factors in food choice?
In the end, I think we need a both/and approach, but I think that alt proteins are the only approach that has a shot at slashing the global consumption of industrial animal meat.
This seems self-contradictory: why would you support another solution, if you think alternative proteins are “the only approach that has a shot”? By assumption, that other solution would not have a shot.
I look forward to your comments on my forthcoming work on other strategies to reduce meat usage. I’ll let you have the last word here.
Thanks for clarifying w/r/t strong form PTC theory—that’s helpful. I think it makes sense to focus on taste, price, and nutrition as the three factors that are absolutely necessary for success; we can address other factors later (or let private companies address those other factors later). Sorry that caused you some confusion, though I think you took an untenable leap with your assumptions.
W/r/t “many times the penetration” and “huge, huge dent,” I think that will depend a lot on what happens between now and reaching price/taste/nutrition parity. But the numbers in your hypothetical discrete choice experiments are extremely promising (for the reasons already discussed). Surveys w/r/t cultivated meat are equally promising—and as discussed, this is all in a world where the products don’t yet exist and many/most consumers are dubious that they’re even possible (i.e., survey respondents don’t think taste and price parity are possible, so they simply reject the premise—and still acceptance numbers are extremely high).
W/r/t your four critiques of the early studies:
For anyone who doesn’t remember what the four critiques are, here you go:
These studies generally don’t find PTC to be the top three factors in determining food choice.
The rankings in these studies reflect what people perceive as the most important factors rather than what would actually cause them to change their diets.
The cited studies were designed primarily to investigate the role of a few particular factors in food choice rather than to identify the most important factors.
These studies analyze the average ranking of each factor rather than how individual consumers rank the factors.)
On the first point, the studies mostly find price and taste to be most important. That said, even if all four critiques are totally accurate, that just indicates subpar study design and doesn’t mean that the conclusions are wrong. We spent the rest of our back-and-forth discussing other studies and evidence, all of which point (IMO) to the importance of taste and price to food choice.
As our subsequent back-and-forth indicates, there’s overwhelming additional evidence that taste and price are critical aspects of consumer food choice—both generally and specifically w/r/t alternative meats. For example, your chosen examples (the ten hypothetical discrete choice experiments, three commercial case studies, and the Malan 2022 field experiment) all indicate the critical importance of taste and price to food choice, as discussed in my first response to your article.
On your final point: While I don’t think we’re going to decrease meat consumption globally unless alternative proteins succeed, that doesn’t mean that nothing else is important. A few reasons why:
First, my view that we need taste/price/nutrition-competitive products in order to decrease meat consumption globally doesn’t mean we need only those things (this was a big part of our back-and-forth, of course).
Second, we don’t know if alt meats can reach taste & price parity (we’re optimistic, but no one has ever done it). Efforts that cut consumption are valuable, even if they won’t scale.
Third, it’s education about the harms of industrial animal agriculture that motivated most people who are currently leading the charge on alt proteins, farm animal welfare, and more; there are significant and valuable outcomes beyond a global decrease in meat consumption.
Fourth, the best (I think) way we convince the early adopters to consume the current products is by making the nutrition case for alt proteins (i.e., education).
I could keep going, but you get the idea—saying “we need to reach taste and price parity to decrease industrial meat consumption” is not the same as saying “taste and price parity are the only things worth working on.”
Thanks Jacob—nice of you to give me the last word; I hope I didn’t abuse that privilege.
