If you don't know the people doing work in this field today, and instead are just Googling "heritability of IQ numbers" (which would explain the Wilson Effect paper you kind of inexplicably posted) you can find previous threads that I've discussed this in using the search bar below. Either way, "you probably just made this up" is not OK on HN.
Do you have any argument as to why what a social scientist says today is more valid than what one said 20 years ago?
I'd trust social scientists less today than 20 years ago due to the effect of social media on them. Social media creates much stronger social pressure on people to conform, and that isn't a good thing for science.
Ah ok, yeah genetics science has came a long way 20 years so there it makes more sense to listen to modern stuff, but why the scare quotes? Do you have a problem with social scientists?
Edit: Looked him up and he disagrees with you. "My sense is that heritability of IQ is in the range of 30-70% with very high confidence.", you said "It's likely somewhere between 15%-50%". There is a massive difference between 30-70 and 15-50, 30-70 sounds much more reasonable and matches most studies on the subject I have seen.
