This _should_ just be more social-science nerd stuff, the sort of thing that would only draw your attention if, like me, you feel bad about not being smart enough to do algebraic topology and want to console yourself by at least knowing about the Science of not being smart enough to do algebraic topology. The reason everyone _and her dog_ is still mad at Charles Murray a quarter of a century later is Chapter 13, "Ethnic Differences in Cognitive Ability", and Chapter 14, "Ethnic Inequalities in Relation to IQ". So, _apparently_, different ethnic/"racial" groups have different average scores on IQ tests. [Ashkenazi Jews do the best](https://slatestarcodex.com/2017/05/26/the-atomic-bomb-considered-as-hungarian-high-school-science-fair-project/), which is why I sometimes privately joke that the fact that I'm [only 85% Ashkenazi (according to 23andMe)](/images/ancestry_report.png) explains my low IQ. ([I got a 131](/images/wisc-iii_result.jpg) on the [WISC-III](https://en.wikipedia.org/wiki/Wechsler_Intelligence_Scale_for_Children) at age 10, but that's pretty dumb compared to some of my [robot-cult](/tag/my-robot-cult/) friends.) East Asians do a little better than Europeans/"whites". And—this is the part that no one is happy about—the difference between U.S. whites and U.S. blacks is about Cohen's _d_ ≈ 1. (If two groups differ by _d_ = 1 on some measurement that's normally distributed within each group, that means that the mean of the group with the lower average measurement is at the 16th percentile of the group with the higher average measurement, or that a uniformly-randomly selected member of the group with the higher average measurement has a probability of about 0.76 have having a higher measurement than a uniformly-randomly selected member of the group with the lower average measurement.)
-Given the tendency for people to distort shared maps for political reasons, you can see why this is a hotly contentious line of research. Even if you take the test numbers at face value, racists trying to secure unjust privileges for groups that score well, have an incentive to "play up" group IQ differences in bad faith even when they shouldn't be [relevant](https://www.lesswrong.com/posts/GSz8SrKFfW7fJK2wN/relevance-norms-or-gricean-implicature-queers-the-decoupling). As economist Glenn C. Loury points out in _The Anatomy of Racial Inequality_, cognitive abilities decline with _age_, and yet we don't see a moral panic about the consequences of an aging workforce, because older people are construed as an "us"—our mothers and fathers—rather than an outgroup. _Individual_ differences in intelligence are also presumably less politically threatening because "smart people" as a group aren't construed as a natural political coalition—although Murray's work on cognitive class stratification seems to suggest this intuition is mistaken.

It's important not to overinterpret the IQ-scores-by-race results; there are a bunch of standard caveats that go here that everyone's treatment of the topic needs to include. Again, just because variance in a trait is statistically associated with variance in genes _within_ a population, does _not_ mean that differences in that trait _between_ populations are _caused_ by genes: [remember the illustrations about](#heritability-caveats) sun-deprived plants and internet-deprived red-haired children. Group differences in observed tested IQs are entirely compatible with a world in which those differences are entirely due to the environment imposed by an overtly or structurally racist society. Maybe the tests are culturally biased. Maybe people with higher socioeconomic status get more opportunities to develop their intellect, and racism impedes socio-economic mobility. And so on.
The problem is, a lot of the blank-slatey environmentally-caused-differences-only hypotheses for group IQ differences start to look less compelling when you look into the details. "Maybe the tests are biased", for example, isn't an insurmountable defeater to the entire endeavor of IQ testing—it is _itself_ a falsifiable hypothesis, or can become one if you specify what you mean by "bias" in detail. One idea of what it would mean for a test to be _biased_ is if it's partially measuring something other than what it purports to be measuring: if your test measures a _combination_ of "intelligence" and "submission to the hegemonic cultural dictates of the test-maker", then individuals and groups that submit less to your cultural hegemony are going to score worse, and if you _market_ your test as unbiasedly measuring intelligence, then people who believe your marketing copy will be misled into thinking that those who don't submit are dumber than they really are. But if so, and if not all of your individual test questions are _equally_ loaded on intelligence and cultural-hegemony, then the cultural bias should _show up in the statistics_. If some questions are more "fair" and others are relatively more culture-biased, then you would expect the _order of item difficulties_ to differ by culture: the ["item characteristic curve"](/papers/baker-kim-the_item_characteristic_curve.pdf) plotting the probability of getting a biased question "right" as a function of _overall_ test score should differ by culture, with the hegemonic group finding it "easier" and others finding it "harder". Conversely, if the questions that discriminate most between differently-scoring cultural/ethnic/"racial" groups were the same as the questions that discriminate between (say) younger and older children _within_ each group, that would be the kind of statistical clue you would expect to see if the test was unbiased and the group difference was real.
-Hypotheses that accept IQ test results as unbiased, but attribute group differences in IQ to the environment, also make statistical predictions. Controlling for parental socioeconomic status only cuts the black–white gap by a third.

+Controlling for parental socioeconomic status only cuts the black–white gap by a third. (And note, on the hereditarian model, some of the correlation between parental SES and child outcomes is due to both being causally downstream of genes.)

And so on.
-In mentioning these arguments in passing, I'm _not_ trying to provide a comprehensive lit review on the causality of group IQ differences. (That's [someone else's blog](https://humanvarieties.org/2019/12/22/the-persistence-of-cognitive-inequality-reflections-on-arthur-jensens-not-unreasonable-hypothesis-after-fifty-years/).) I'm not (that) interested in this particular topic, and [without having mastered the technical literature, my assessment would be of little value](https://www.gwern.net/Mistakes#mu). Rather, I am ... doing some context-setting for the problem I _am_ interested in, of fixing public discourse. The reason we can't have an intellectually-honest public discussion about human biodiversity is because good people want to respect the anti-oppression Schelling point and are afraid of giving ammunition to racists and sexists in the war over the shared map. "Black people are, on average, genetically less intelligent than white people" is the kind of sentence that pretty much only racists would feel _good_ about saying out loud, independently of its actual truth value. In a world where most speech is about manipulating shared maps for political advantage rather than _getting the right answer for the right reasons_, it is _rational_ to infer that anyone who entertains such hypotheses is either motivated by racial malice, or is at least complicit with it—and that rational expectation isn't easily cancelled with a _pro forma_ "But, but, civil discourse" or "But, but, the true meaning of Equality is unfalsifiable" [disclaimer](http://www.overcomingbias.com/2008/06/against-disclai.html).

To speak to those who aren't _already_ oblivious science nerds—or are committed to emulating such, as it is scientifically dubious whether anyone is really that oblivious—you need to put _more effort_ into your excuse for why you're interested in these topics. Here's mine, and it's from the heart, though it's up to the reader to judge for herself how credible I am when I say this—
I take strong issue with Murray's specific examples here—as an [incredibly bitter](http://zackmdavis.net/blog/2012/12/a-philosophy-of-education/) autodidact, I care not at all for formal school degrees, and as my fellow nobody pseudonymous blogger [Harold Lee points out](https://write.as/harold-lee/seizing-the-means-of-home-production), the domestic- and community-focused life of a housewife actually has a lot of desirable properties that many of those stuck in the technology rat race aspire to escape into. But after quibbling with the specific illustrations, I think I'm just going to bite the bullet here?
-_Yes_, intellectual ability _is_ a component of human worth! Maybe that's putting it baldly, but I think the _alternative_ is obviously senseless. The fact that I have the ability and motivation to (for example, among many other things I do) write this cool science–philosophy blog about my delusional paraphilia where I do things like summarize and critique the new Charles Murray book, is a big part of _what makes my life valuable_—both to me, and to the people who interact with me. If I were to catch COVID-19 next month and lose 40 IQ points due to oxygen-deprivation-induced brain damage and not be able to write blog posts like this one anymore, that would be _extremely terrible_ for me—it would make my life less-worth-living. And my friends who love me, love me not as an irreplaceably-unique-but-otherwise-featureless atom of person-ness, but _because_ my specific array of cognitive repetoires makes me a specific person who provides a specific kind of company. There can't be such a thing as _literally_ unconditional love, because to love _someone in particular_, implicitly imposes a condition: you're only committed to love those configurations of matter that constitute an implementation of your beloved, rather than someone or something else.

Murray continues—
I agree with Murray that this kind of psychology explains a lot of the resistance to hereditarian explanations. But as long as we're accusing people of motivated reasoning, I think Murray's solution is engaging in a similar kind of denial, but just putting it in a different place. The idea that people are unequal in ways that matter is [legitimately too horrifying to contemplate](https://www.lesswrong.com/posts/faHbrHuPziFH7Ef7p/why-are-individual-iq-differences-ok), so liberals [deny the inequality](/2017/Dec/theres-a-land-that-i-see-or-the-spirit-of-intervention/), and conservatives deny [that it matters](https://www.lesswrong.com/posts/NG4XQEL5PTyguDMff/but-it-doesn-t-matter).
+But I think if you _really_ understand the fact–value distinction and see that the naturalistic fallacy is, in fact, a fallacy (and not even a tempting one), that the progress of humankind has consisted of using our wits to impose our will on an [indifferent universe](https://www.lesswrong.com/posts/sYgv4eYH82JEsTD34/beyond-the-reach-of-god), then "too horrifying to contemplate" fails to compute. The map is not the territory: _contemplating_ doesn't make things worse.
+
+The author of the _Xenosystems_ blog mischievously posits [five stages of knowledge of human biodiversity](http://www.xenosystems.net/five-stages-of-hbd/) (in analogy to the famous, albeit [reportedly lacking in empirical support](https://en.wikipedia.org/wiki/K%C3%BCbler-Ross_model), five-stage Kübler-Ross model of grief), culminating in Stage 4: Depression ("Who could possibly have imagined that reality was so evil?") and Stage 5: Acceptance ("Blank slate liberalism really has been a mountain of dishonest garbage, hasn't it? Guess it's time for it to die ..."). I think I got stuck halfway between Stage 4 and 5.
