Are you saying that they ignore IQ altogether? Or are you saying that they don't take IQ to be the sole and ultimate cause? And, in either case, what is your evidence for how they treat IQ? I don't recall their mentioning it during the diavlog, but I'm sure that they didn't mention a lot of things that are in the book.
Someone could concede that IQ is a significant factor for individual earnings, and yet still be more interested in other factors, such as personal identity. Given that interest, it makes sense to explore those other factors and not to spend much time on IQ. That seems to me to be perfectly consistent with truth-seeking. Science can't progress without this kind of division of labor.
