+> The real lesson of “twins studies plus anthropology” is that you have to control almost all of a person’s environment to have a major impact, but a major impact indeed can be had. I behave very differently than my Irish potato famine ancestors, and not because I am genetically 1/8 from the Madeira Islands. That said, within the narrower range of environmental variation measured in twins studies…well those studies seem to be fairly accurate.

+
+Footnote 4 to the introduction of Part III recaps the argument. If the black/white IQ gap in the U.S. were caused by racism, you'd predict that blacks would have higher IQs in countries where they're the ruling majority, like in Haiti or most of sub-Saharan Africa, but they don't. You might think racism affects IQ by means of its affect on socioeconomic status (SES), but adjusting for parental SES only diminishes the gap by a third.

+
+You might think that the tests are culturally biased, but if that were true, you'd expect the distortion
+
+(And on the hereditarian model, parental SES could be caused by parental cognitive abilities.)

+
+> I think at the root is the new upper class's conflaction of intellectual ability and the professions it enables with human worth. Few admit it, of course. BUt the evolving zeitgeist of the new upper class has led to a misbegotten hierarchy whereby being a surgeon is _better_ in some sense of human worth than being an insurance salesman, being an executive in a high-tech firm is _better_ than being a housewife, and a neighborhood of people with advanced degrees is _better_ than a neighborhood of high-school graduates. To put it so baldly makes it obvious how senseless it is. There shouldn't be any relationship between these things and human worth. And yet, among too many in the new upper class, there is.
+
+As [Harold Lee points out](https://write.as/harold-lee/seizing-the-means-of-home-production),
+
+> The conflcation of intellectual ability with human worth helps to explain the new upper class's insistence that inequalities of intellectual ability must be the product of environmental disadvantage. Many people with high IQs really do feel sorry for people with low IQs. If the environment is to blame, then those unfortunates can be helped, and that makes people who want to help them feel good. If genes are to blame, it makes people who want to help them feel bad. People prefer feeling good to feeling bad, so they engage in confirmation bias when it comes to the evidence about the causes of human differences.

+ And, again, socio-psychological facts like character assessments are precisely those for which we have the _most_ reason to distrust each other's judgement: if I like Mary, I might say favorable but false things about her even if I would never tell a lie about homotopy groups. In the absence of a objectively calibrated compassion-o-meter, psychological scientists who want to study individual differences in compassion are mostly limited to doing statistics on people's verbal self-reports and other-reports—but if you don't trust what people _say_, it's at least not _obvious_ whether or how much more you should trust statistical analyses of what people say, in accordance with the ancient dictum: ["garbage in, garbage out."](https://en.wikipedia.org/wiki/Garbage_in,_garbage_out) Probably the neuroscientists are working on the compassion-o-meter, but they too face the problem of ensuring that their interpretations of their brain scans actually mean what they say they mean.

+> the test must measure, in addition to the construct it purports to measure,
+some other characteristic or factor that is completely uncorrelated with the construct and on which the major group, on the average, exceeds the minor group A typical example is the case in which the major and minor groups differ in their native language. A person’s native language is presumably not correlated with the construct of intelligence. If the test involves the native language of the major group exclusively and the minor group has a different language, the test will most likely be positively biased in favor of the major group. In other words, the test is measuring something (in this case a specific language) in addition to the construct that it purports to measure, which condition favors the major group

No significant difference (the difference actually amounts to less than 1 IQ point) was found between the nonstandard dialect and standard English forms of the Stanford-Binet when administered by two black Es to one hundred black children in a Head Start program in Philadelphia (Quay, 1971).

+A Book Review
+
+Someone wrote a blog post reviewing a book by some sociologist named Murray. Never heard of him. Anyway, I couldn't get through the whole thing because the reviewer has this _really obnoxious_ writing style that uses way too many italics and exclamation points (as well as occasional weirdly out-of-place cuss words?!), but I did notice that he (?) links to _Less Wrong_ a few times (!), which is something I don't see "in the wild" very often these days, so I thought it couldn't hurt to share the link here in case one of you happens to find it interesting??
