The story goes that Galileo, forced to recant his belief that the Earth orbits the sun, muttered a defiant 'and yet, it moves,' as his inquisition ended. Good line. Except in my feed, people have been invoking it on behalf of another science icon & his belief in racial hierarchy. 
The Galileo tweets are responding to news that @CSHLaboratory is removing the name of Jim Watson, the Nobel-winning biologist, from its graduate school. Watson said in a documentary last year that he thinks IQ differences between Blacks and whites reflect genetic differences.
So to be clear, these tweets are saying, "You can take Watson's name off the school, but the genetic inferiority of Black people still stands." "Watson," they are saying, "was persecuted by science-deniers, just like Galileo."
Watson's sad decision, at age 90, to tie his legacy to racism doesn't need rehashing, IMO (he's now 92). And there's nothing new about claims by white people that racial disparities in income, wealth, incarceration, etc are the product of genetics rather than social policy/power.
But the Galileo tweets don't just (wrongly) invoke science in the name of racist ideology, they also lay claim to scientific integrity. 'Not only is it true that white people are better than Black people,' they say, 'it's super-courageous to say so! We should really get a medal.'
It's bad to give bandwidth to trolls, but the Galileo thing has come up before and it really annoys me. I also know from other reporting that a lot of non-trolls are confused about whether genetic variants associated with 'race' are known to cause different IQ/behavior. (No).
So here's a thread of some of my reasons for why the Galileo-Watson analogy is trash, and few other responses to people casting their unfounded views on race/IQ as heroic because, supposedly, they're being persecuted aka canceled.
1) Galileo based his belief that the Earth revolves around the sun on evidence about the movement of Jupiter’s moons and the phases of Venus. Watson's belief that the average IQ difference between Blacks and whites is genetic is not based on evidence, because none now exists.
2) Watson defenders say "The absence of evidence is not evidence of absence, he's free to speculate either way!" But Watson is a science icon, so people take his unsupported speculation as truth. Which is why @CSHLaboratory called his comments both 'unsubstantiated' & 'reckless.'
3) Watson defenders say "Scientists are supposed to explore all possibilities!'' . But it's gross to suggest idle speculation on a topic linked to some of history's worst atrocities is the mark of a good scientist. per @DocEdge85
4) And that's another difference - Galileo was persecuted for speaking truth (heliocentric solar system) to power (Catholic Church). Watson was repudiated by Cold Spring Harbor for statements that rationalize the political and economic power of the group that already holds it.
5) Watson defenders say "We're RIGHT to assume genetic differences in lots of traits arose in geographically isolated populations-David Reich says so!'' . OK but Reich (& all other population geneticists) also say "we have no idea yet'' what those might be.
6) Watson defenders say 'But those differences PROBABLY align with our racial stereotypes!' There's no basis for thinking this. Americans inherit an environment shaped by racism along with our genetic ancestry. There's no method to cleanly decouple them... academic.oup.com/view-large/fig…
...and signs that natural selection may have acted differently on a trait across human populations are open to other interpretations. Links that help explain: geneticshumanagency.org/gha/correlatio… arxiv.org/abs/1909.00892
