I appreciate your thoughtful comments. Inspired by these discussions, I believe I've sharpened my understanding of this subject considerably. When it comes to accounting for observed differences between different groups, the following statements are the only two possible explanations: (a) Genetic factors contribute to differences in outcomes (b) Non-genetic factors contribute to differences in outcomes Note that the two are not mutually exclusive. For example, when you write Does that mean that Americans are genetically superior to Europeans? No, it's that they had access to more resources on a bare continent, which led to a positive feedback loop of wealth and creation. you are arguing for (b). But because (a) and (b) are not mutually exclusive, this is not a valid argument against (a). Indeed, virtually the entire mainstream discussion around group differences consists of increasingly strong statements in favor (b), without ever addressing (a) directly. This isn't to say (a) is always true, just that you need direct evidence to dismiss it. For example, given the observation that any human being with the ability to learn a language can learn any language, (a) appears to be false with respect to acquiring specific natural language (as opposed to language acquisition generally, which of course is genetically based). So, why is it that so many otherwise clear thinkers fail to see that arguments for (b) aren't arguments against (a)? My guess is that most people who believe in (b) and only (b) implicitly apply the following reasoning: The non-genetic factors in group differences are so numerous, egregious, and well-documented that they plausibly account for all known differences in outcomes between people of different ancestry. Therefore, genetic factors are probably irrelevant or negligible. Unfortunately, this reasoning is faulty. For example, there is no a priori way to know how big an effect discrimination will have, and hence no way to rule out (a) without direct evidence. As to your other points, I agree completely that we should treat people on an individual basis, without discriminating on the basis of ancestry, gender, etc. Furthermore, I believe in finding and cultivating talent anywhere it exists, regardless of background. I hope you agree.

This is too meta -- they're not exclusive, but the structure of the argument is pretty clear. The burden of proof falls on the one making the claim. If you are claiming (a) or (b), you need to justify it. I haven't seen credible evidence for (a). I'm not refuting it because I don't have the burden of proof. Answering Yali's question requires at least one of (a) or (b). If (b) were false, then that would imply (a). Providing evidence for (b) rules out the argument based on elimination.

  No, the burden of proof is on those who claim not-(a), because it is evident at a glance that there are at least some genetic difference between groups. (Detailed genetic analysis, of course, confirms this. Noted anti-racist Henry Louis Gates Jr. has a whole show about it. [1]) There's no law of biology that says evolution only works on physical traits; quite the opposite. Therefore, the burden of proof is on the claim that any particular cognitive or behavioral characteristics have no genetic component. Answering Yali's question requires at least one of (a) or (b). If (b) were false, then that would imply (a). Providing evidence for (b) rules out the argument based on elimination. It is impossible to use the process of elimination when the alternatives are not mutually exclusive. I.e., this reasoning is specious: Why are men generally stronger than women? Well, men lift weights more often than women. Therefore, strength differences have no genetic basis. So it goes with Yali's question. You, and Jared Diamond, are obviously smart enough to understand this completely. But the conclusions are heretical, which is the only reason I can think of for why you fail to do so.

    There are genetic differences between groups, but claim (a) is that there are such differences that contribute (substantively) to different outcomes -- as you wrote yourself. I don't know of any such evidence. It's controversial to say the least, but if you are engaging me in a discussion, you have the burden of proof on that point. As mentioned, I don't really care for these types of discussions, because either way, it's not going to lead me to change my actions. My original motivation was to see what moldbug thinks of Jared Diamond's work (i.e. if he tries to refute it) (a) and (b) aren't exclusive, but it could be that one contributes vastly more to the observed outcomes than the other. I happen to believe that this is the case with (b), as Jared Diamond explains. There is just much less evidence supporting (a) compared to that supporting (b). I think you misread my last statement. Providing evidence for b means that you can't apply the argument that if b were false, then a. They are not exclusive, but at least one of them is necessary. I would assume (b) is false without evidence as well.
