IQ is largely a pseudoscientific swindle

Hurling ordure at the TREACLES, especially those closely related to LessWrong.
AI-Industrial-Complex grift is fine as long as it sufficiently relates to the AI doom from the TREACLES. (Though TechTakes may be more suitable.)
This is sneer club, not debate club. Unless it's amusing debate.
[Especially don't debate the race scientists, if any sneak in - we ban and delete them as unsuitable for the server.]

For anyone who hasn't watched it this video is an excellent breakdown of the racist history of both The Bell Curve and of IQ tests.
Using that same logic, Hitler was a vegetarian, so vegetarians must be racist.
Or, a more mature response, sometimes real things get misused by racists. IQ test predict performance with the same self-identified racial groups, so what explains that? It can't be racism, since they are the same race.
oh do fuck off
Here's two studies that tested for heritability of IQ.
1 2
No source here so I can only assume where you got this data. The most commonly cited source for this is the one used in The Bell Curve which compared test scores of black children in America immediately post segregation and apartheid South Africa against white American children. So, like, obviously the segregated underclass in two deeply racist countries is gonna have a lower quality of education.
I never said it was genetically heritable, my point is simply that it's predictive of future life outcomes.
The source being the National Longitudinal Study of Youth, which has shown this with each cohort tested.
It's gonna take me a bit to figure out how to use the website for NLSY79 so bear with me on that.
The youngest of the cohort in 1979 was 14, since segregation was only officially ended in 1965, it once again seems more likely the legacy of segregation and America's continued racist culture had a larger impact on outcomes than IQ test scores to me.
But, I'm a biologist not a sociologist, so not really my field of expertise.
Edit: the National Longitudinal Study of Youth doesn't even test for IQ, this has been a waste of time.
sorry you had to deal with this lying racist shithead. let me know if hexbear deals with them in a satisfactory way — it’s always good to know how other instances deal with “polite” racist shitheads who try to slip their bullshit in under a thin veneer of misapplied science
Everything in this ignores what I said in my first comment: this persists within the same racial group
Segregation explains nothing about why people of the same race would perform differently based on IQ scores when they were young.
Yes it does, it's one of the most widely cited studies for IQ research. My uni had the class do a research project based on this study, you might just be looking at the wrong page.
It doesn't, see attached screenshot of tests carried out on the cohort.
The ASVAB is considered one of the accepted forms of IQ tests, as long it is proctored, like the NLSY does.
Other studies might use other IQ tests like the Wechsler Adult Intelligence Scale or Raven's Progressive Matrices Test.
The use of ASVAB score as a stand-in for IQ is contentious amongst researchers.

What's more, higher scores on WAIS and ASVAB are even less correlated with eachother than lower scores.
