And these people have directly stated their opposition comes on ideological grounds ('science for the people' etc.), and this is supported by reports from their colleagues. One cannot attack hereditarians for being political extremists. IQ researchers are center-left on average.

I have come to have very large distrust in philosophers. The fact that they keep making the same trite arguments about heritability without reference to empirical work for 5 years I think is extremely damning. Why do they keep repeating their strawmen of Jensen, for instance?

I don't like Rushton's work for methods reasons, seems I was somewhat right in this view if we are to take Dutton's biography seriously (I haven't read it). I am sympathetic to traditional leftism, and environmentalism (esp. work safety), so I am happy you choose to engage. :)

Attacking hereditarianism on grounds of... not accepting abduction is certainly a bold move. But not one that would convince anyone not already in agreement. Everybody uses abduction in real life, and it fits well with a coherentist view of justification IMO.

I haven't read his book yet, so maybe I just don't understand what it is he's arguing from your summary. I am disinclined to spend much time on philosophy myself since I think it detracts from much more important science. Sesardic, Cofnas et al will probably engage. I'll ask.

I completely disagree. I think it is much more productive to just get more scientific findings out. The issue can be solved with genomics is very near future, I don't think philosophy has much to contribute here. Tbh, I do not care very much what philosophers think of the topic.
