Taleb dunking on IQ “research” at length. Technically a seriouspost I guess.

    Here’s two studies that tested for heritability of IQ.

    1 2

    IQ test predict performance with the same self-identified racial groups, so what explains that?

    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.

          the National Longitudinal Study of Youth doesn’t even test for IQ, this has been a waste of time.

          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.
