I read the Vox transcript. It looks like Sam's in a loop, where he says he's not an IQ expert, doesn't care about any of it, he just wants to argue the data and not policy, but then when Ezra, who's comparatively an expert on it all wants to argue about data and Murray's agenda, Sam goes back to "I'm not an IQ expert", don't care, rinse and repeat.
If Sam wants to argue that Murray has been unfairly maligned, Sam needs to have some expertise on the issue, outside of "I read Murray's book and it seems legit to me!"
Sam's
also almost implying there's some secret scientific consensus that agrees with Murray, because some scientists emailed Sam and expressed a private agreement with them. This is...what are we supposed to do with that claim?
Has Sam come across stuff like this?
https://www.researchgate.net/profil...p-on-Ravens-Advanced-Progressive-Matrices.pdf
This study addresses recent criticisms aimed at the interpretation of stereotype threat research and methodological weaknesses of previous studies that have examined race differences on Raven’s Advanced Progressive Matrices (APM). African American and White undergraduates completed the APM under three conditions. In two threat conditions, participants received either standard APM instructions (standard threat) or were told that the APM was an IQ test (high threat). In a low threat condition, participants were told that the APM was a set of puzzles and that the researchers wanted their opinions of them. Results supported the stereotype threat interpretation of race differences in cognitive ability test scores. Although African American participants underperformed Whites under both standard and high threat instructions, they performed just as well as Whites did under low threat instructions.
He seems to be completely unwilling to consider the idea that the consensus that TBC is quackery is real, and exists for a good reason.
Sam tells Ezra at one point in
the discussion:
There are many errors of this kind that you and Nisbett and Turkheimer are making when you criticize me and Murray. You criticize Murray for errors that he didn’t make.
And in order for you to imagine that I’m equally biased, because you must imagine bias on my side, why am I getting it so wrong? Why am I looking at the same facts that Nisbett and Turkheimer and Harden are looking at and I am getting it absolutely wrong? You have to imagine that I have an equal and opposite passion, that I feel equally righteous, but it’s pointing in the opposite direction. I would have to be a grand dragon of the KKK to feel an equal and opposite bias on these data. You’ve already said you don’t think I’m a racist, but that’s what it would have to be true of me to be as biased as you are
Umm...what?
Sam's been put on the SPLC's hate list
next to neonazis over this. His ego is naturally
hugely threatened. His bias at this point is
extraordinary.
He's not thinking clearly.
When Ezra says:
I do want you to know, you mentioned James Flynn here. To prepare for this conversation, I called Flynn the other day. I spoke to him on Monday. His read of the evidence right now, and this is me quoting him. He says, “I think it is more probably than not that the IQ difference between black and white Americans is environmental. As a social scientist, I cannot be sure if they have a genetic advantage or disadvantage.”
...it doesn't sink in at all. They go back and forth on it and Sam, you imagine him just sort of shaking his head and going "Nu uh!"
Sam keeps trying to say he's arguing the "empirical science", but he's not. Ezra's doing more of than than Sam is.
Finally, a
side note I'm going to throw in since I just ran across it: Men and women are about equal in natural mathematical aptitude:
Reported here are results of a field experiment that tested the usefulness of the stereotype threat formulation for understanding women's performance in upper levels of college mathematics — men and women who are highly motivated and proficient mathematicians and who are in the pipeline to mathematics and science professions. Our primary hypothesis was confirmed. Test performance of women in a stereotype-nullifying presentation of the test in an experimental group was raised significantly to surpass that of the men in the course. In a control group, in which test-takers were given the test under normal test instructions, women and men performed equally.
