This is a solid talk, but everyone remember that despite his extensive knowledge he does have strongly leaning opinions within a still very disputed area of study that is the G factor and intelligence.

They are certainly important, but in my opinion we still don't understand enough to make many of the bold claims he makes. The 80% gene variability take, for example, is not a very common one among those studying intelligence. Orphaned twin studies in the US showed a 40-60% gene vs environment variance.,(reply>), Would love to see pointers to thoroughgoing, balanced literature on this, I routinely see this topic bought up by Silicon Valley types who want to make arguments against hiring Black people
