Is EA just about population growth?

Introduction

Would you rather have a world with X or would you rather save Y lives? People make idiosyncratic life decisions. Well-intentioned people desire to maximize their “impact.” What does “impact” mean? Some argue that “impact” is discoveries about truth (as is the pursuit of most of the physical sciences). Some argue that it is creating works of art or original ideas (as in the case of many musicians and authors). Many people spend their entire lives pursuing such goals and, to the musician, it is worth spending an entire life creating art.

But imagine you had the power to choose between a world where there were another 50 hit songs versus a world where someone who would have been dead was now alive. What would you choose?

Those that argue that saving lives is the be-all-end-all would count an extra 50 hit songs as frivolous—no matter the reach, quality, or novelty of music. It is never worth a life. Those that are ruthlessly pragmatic and quantitative (i.e. economists) try to argue that the “biggest” impact is to save lives. After all, death is irreversible, and what worth is art without people to enjoy it, and what worth is truth if it leads to greater destruction (as Einstein regretted creating the atomic bomb)?

I want to challenge the claim that creating “impact” implicitly means “saving lives.”[1]

Argument

Let us go back to the central claim: “The goal of a life well-lived is to save lives.” At face value, this seems like a noble cause. After all, as Peter Singer has pointed out, anyone who sees a baby drowning in a pool will gladly jump in, save the baby’s life, and feel appropriately self-satisfied.

Yet, this easily goes into an endless regression, where I am living to save other people; other people are living to save me; we are all living to keep all of us alive, together. This seems to imply the goal of a life well-lived is to propagate humanity. If we maintain the environment, it is to ensure that humanity can survive. If we prevent nuclear war, it is to ensure that humanity grows. Surely a noble cause?

Consider that the global population, according to UN forecasts,[2] will peak and may fall in the future. This is because women who are more educated, who are happier with their lives, who are richer, have fewer kids.[3] And, in a counterfactual world, these women, often in richer countries like those of the EU or the US, would have more kids, had they been poorer and had fewer opportunities for birth control, education, and a stable career.

Now, if we continue staring into this crystal ball—this counterfactual world where women have more babies—we would see that there are more lives in this world. Wait—if the goal of a life well-lived is to save other lives, then this counterfactual world in this crystal ball is better.

So, we cannot both believe that educating women is good and that “the goal of a life well-lived is to save other lives.” More educated women lead to fewer lives!

Counterarguments and Rebuttals

Now, most of you are scrunching your eyebrows. This does not seem right, you say. Perhaps the lives of the kids would be more miserable, as there would be fewer women working, lower overall GDP,[4] and (especially) lower standards of living for women. So, perhaps we ought to adjust the beginning claim to something like “the goal of a life well-lived is to maximize quality-adjusted life years of humanity.”[5] At last, this feels appropriate, as we have a statement that incorporates the obvious problem that a miserable life is certainly not a life worth living.[6]

Still, let’s say you are a god controlling this crystal ball, this counterfactual universe. If I were to give you the choice between educating a girl and giving her a career versus saving three lives from death, what would you choose? Consider that those three lives have an equal chance of being male and female, and will likely eat, smile, cry, and live life like everyone else in that society.

Most people who want to make a difference in the world, who seek to have a greater “impact” would choose the second option. For the feminists who chose the former, kudos; you are a minority, unfortunately.

Now, at this point, most of you are still feeling uneasy. You will tell me, “Well, there is a difference between lives that don’t yet exist and lives that already do exist. The woman’s life does exist, and the three children do not.”

True! But there’s something wrong with that statement, too. We do care about lives that don’t yet exist. We make sweeping statements like, “This is for our grandchildren.” Or, just the same, we vow to preserve the environment or obtain greater wealth to pass on. We often do things for people that do not yet exist, and who we do not know will ever exist. And if the goal of life is to maximize quality-adjusted life years, surely it is meant to maximize quality-adjusted life years for all people in the future as well as the present?[7]

One easy way of solving this is by discounting future lives, just as a financier discounts money. We could say, “We believe that this woman’s quality of life is important and that her children’s lives are important. But each of her children’s lives is only worth 15 of her life because they are in the future.” Now, I think this is a rather clean solution to this dilemma, but others have argued vehemently against this. By discounting future lives, we are inevitably discounting actions today that could affect people 100 years in the future, which would be disastrous for many people in the future. Our decision-making would be hampered, as we would value those future lives very little after all the discounting is done (consider long-run risks such as climate change).

Other people say that the reason this comparison is not appropriate is that a woman ought to have the choice to have kids and that anything that takes away this choice is abhorrent. The sentiment is, “You should educate the girl because that allows her to have a choice to have kids. The number of kids she has is her decision, so you should respect that.” However, a generation ago, that same woman would have no qualms about having kids. In our counterfactual world, where she does not receive as much education, she would just consider it a natural part of life, choice or not. Of course, improving the opportunity to choose between different lifestyles is important, but to what extent? How much happiness does she gain, and is it greater than the combined happiness and lives of three people that otherwise would not have existed?

Conclusion and Summary of Argument

I don’t have the answer. But something is wrong here. I chose women’s education because it was the most obvious example linked to population growth, but it is not the only one. I could have chosen anything we consider “good” that decreases the number of births. We cannot both argue for saving lives and simultaneously argue for a smaller population, no matter how ostensibly “good” the policy is. If saving lives is the goal, then in almost every case (barring a significant drop in quality of life), we would choose the world where there are more lives.

Formally laid out, my argument is the following:

  • Suppose, towards a contradiction, that the goal of life is to save lives.

  • We know educating women more is good and would be done in an ideal world.

  • Increasing women’s education leads to fewer lives because of declining fertility.

  • Therefore, the goal of life must not be to save lives.

Endnotes

[1] The goal of this essay is not to disprove this view, but simply to challenge it, and to give it more rigorous thought. I must disclose that I come into this exercise with no prior philosophical leanings nor any rigorous philosophical training, and this exercise was mostly for myself, a clarification of my thoughts.

[2] See population.un.org/​​wpp/​​Graphs/​​Probabilistic/​​POP/​​TOT/​​900

[3] Up to a point. Of course, it has been shown that this relationship between income and fertility is a J-shaped relationship, but this claim still holds generally.

[4] A caveat to this is that there may be greater growth in GDP with a continually growing population. If this is the case, then we could see this counterfactual world’s wealth eventually exceed that of reality, as it would not be bounded by certain human capital constraints.

[5] Or, to maximize total utility, whatever utility means. But let’s stick to the claim with the quality-adjusted life years.

[6] Although, it is odd that people in misery often do continue to live. So clearly, they are either acting irrationally or they are not as miserable as we make them out to be. See the QALY health science literature on physical ailments like losing a limb. People who do not have the ailment believe life with the ailment to be worse than people who do have the ailment rate life to be. I suspect that this is not the case for psychological ailments, which often do lead to people taking their own lives.

[7] Otherwise, we would just ignore the next generation and live life fully for this one generation—the earth, environment, political institutions be damned.
