Modern Heresy

This is part 1 in a series of videos examining the claims and arguments of Ken Richardson on IQ. In this part I give my initial impressions of his books and respond to the claim that IQ is a proxy for social class.

If enough of you follow me, I might actually start posting regularly.

*Errata*

- I noticed at several points I refer to Richardson's 2017 book as "Genes, Brains, and IQ". The correct title is "Genes, Brains, and Human Potential".

- I wasn't fairly representing the entirety of the Korenman/Winship paper "A Reanalysis of The Bell Curve". See pinned comment.

- Saying that 70% of the IQ variation in society is contained within families is not literally accurate. If I were to re-record that section, I would say something like "siblings differ by 70% of the amount that random strangers differ on IQ, on average".

In terms of the statistical concept of variance, within family variance accounts for about 50% of the variance in society at large.

*** Errata ***

- Apparently Weschler is pronounced Wex-ler. Or at least that's the way Charles Murray, James Flynn, and Arthur Jensen pronounce it.

My analysis of Gould's review of The Bell Curve.

Considering that the cover of the 2nd edition of Gould's book The Mismeasure of Man is tagged with: “The definitive refutation of the argument of The Bell Curve”, in which this review is reprinted, and given the widespread currency of this review in “debunking” The Bell Curve, an in-depth analysis is warranted.

TL;DW: It completely fails
