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

    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.

      Hi, could you perhaps elaborate a bit on the racist history of the bell curve? I'm well aware of the racist history of IQ, but I don't even have an inkling of what that's referring to in the context of the bell curve. It's just the graph of a normal distribution, is this referring to some weird application of it to some racist shit?

      PS: I know you've attached a video with info on it and me asking might be kinda dumb. However, I saw it's 2+hrs and I don't have the time to watch it right now but I'm still interested.

        I feel that my comment was a little ambiguous.

        The Bell Curve mentioned isn't the graph distribution, but rather the book by the same name that uses misrepresented data from IQ tests to push the idea that there is a genetic factor that makes black people inherently less intelligent than anyone else.

        Sorry for any misunderstandings.

        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.

            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
