I can't tell if it's ignorance or cynicism at work here.
Let me fix your summaries:
> In which he downplays racial bias in police shootings
In which a guest on Hsu's podcast, psychologist Joe Cesario, presents in detail his research, some of which is experimental, demonstrating no racial bias in police shootings (not the case in police interactions in general though).
> In which he says lack of segregation is the reason for racial underperformance
In which a guest on Hsu's podcast, Claude Steele, a[n African American] social psychologist, discusses his research in detail and his [African American] co-host, Corey Washington, discusses his daughter's educational experience. (And in which no one suggests that racial segregation in education would be desirable.)
