IQ fans are like "IQ is the most reliable metric ever. Sure, test-retest variation is huge, and retesting is avoided because people get better at the test, meaning the error is unknown, and different tests have huge variation b/w them, but we should reshape all policy around IQ"

I think 'The Selfish Gene' by Richard Dawkins has done untold damage to so many people's understanding of evolutionary biology. It teaches hyper-adaptionist thinking and completely wrong ideas (e.g. "genes = units of selection"). Possibly the most damaging popsci book of all time

I'm concerned that most biologists have a narrow conception of eugenics. Eugenics isn't just cases of historical atrocities (e.g. involuntary sterilisation), it's an ideology: that the quality of society is determined by the gene pool. It has broad implications

The fact that it's an ideology, and not just a set of practices (i.e. involuntary sterilisation of "unfit" members of society) means that it can (and has) evolved with time. Biologists opposed to eugenics need to catch up

Been seeing racists repeat this talking point a lot lately. It originates from this paper Though as far as I can tell, that paper got it wrong & used unrealistic model assumptions. Follow up studies disagree (Ref 7 = paper above)

@whstancil Black people aren’t 20% Neanderthal. West African populations have some (2-19%) admixture of an archaic hominin (likely homo habilis). Neanderthal admixture is predominant in European and Middle Eastern populations.

Now with these technical issues out of the way, for the next part of this thread (to be continued soon), I want to discuss how this study fits into a larger historical context in race/IQ/genetics debates and how it serves to bolster genetic determinism... 25/

Another thing: the transphobe view isn't really about biology, it's about biological determinism. Notice the missing steps between "sex is the design plan to produce sperm or eggs" and "laws should be enacted around this"? The assumption being birth determines one's social role

This definition of sex that transphobes like to stick to (which @Anthrofuentes doesn't misrepresent at all) is *teleology*, not biology. To pass the laws they want, they need an "objective" definition, but biology has outliers, so they arrive at the same nonsense creationists use

The fatal flaw which makes this entire study worthless and false is that estimating the heritability of the study participants says nothing about how malleable IQ is or not. Heritability is not the right tool for this job. 13/

The 'race-IQ' fans love this classic study because they think it supports their ideas about biological race and racial intelligence, etc. But it doesn't. Also the study itself has issues and doesn't generalise, which they consistently ignore.

@Unashamed366 "evolved separately" There's been gene flow b/w adjacent populations throughout history, as seen by 'isolation by distance' patterns in genetic variation "hundreds of millions of years" H. sapiens migrated out of Africa 55-65k years ago "subspecies"

Lots of offended responses from 'race realists' here. The big criticism being that it's presumptions of me to assume that intelligence would be advantageous in all environments, because maybe there's some unknown trade-offs b/w environments...

'Race realists' have never provided a coherent explanation for why/how different environments supposedly selected for high or low intelligence alleles during evolutionary history. High intelligence would be advantageous in all environments!

And the obvious but inconvenient truth of the situation is staring them in the face: 1. the IQ tests themselves don't translate well across cultures or education levels, so aren't measuring "intelligence" 2. Richard Lynn's IQ data is a work of fraud

It's funny how arguing with 'race realists' follows this exact pattern. Every time they realise they can't win the argument based on what the genetics literature actually says, they devolve into creationist-like talking points like "how can evolution be real if race not real??"

Compare and contrast the Weiss article (shown left) with the plaintiff (right). The Weiss article compeltely ommitts that Sabatini... - created a culture of fear - interfered with the investigation by threatening lab members - punished members who didn't engage with his sex talk

New paper argues that predictions from life history theory (r/K selection theory), where harsh environments = "fast" life history strategies (i.e. poor people have more children, etc.), make no biological sense. Historical data indicates the *opposite*

New preprint goes through Gregory Clark's PNAS paper from a few months ago and absolutely rips it to shreds. It's mind-boggling just how amateurish Clark's paper is. Many supposedly serious hereditarian intellectuals gave it their seal of approval too

There does exist genetic data on ancestry and IQ and it looks exactly like hereditarians predicted. Then one of the only people to actually publish a study like this got fired for it, and the NIH now prohibits doing any studies on race and intelligence with genetic data.

Interesting responses from the race science fans here. Normally they say races are subspecies, use dog breeds as an analogy, and share 4chan memes about how races should be considered separate species. Now I'm told they never once believed race was genetically discrete. Ok then.

. @eyeslasho once again demonstrating his stupidity. The PCA plots shown here do not support the idea for a "biological basis for race". On the contrary, they nicely illustrate how human genetic variation is clinal and doesn't cluster into non-continuous groups.
