Note sent to Steve Sailer on narrowing black-white IQ gap:


For what it's worth, GSS vocabulary data support Flynn and Dicken's finding that black and white IQs have converged a bit. The gap went from .79 standard deviations (SDs) in the 1970s to .62 in this decade--a narrowing of .17 SDs. I looked at recent data, and the age group with the highest vocab scores were born in the late 50s and early 60s. Perhaps they escaped both the environmental deficits of segregation and the more recent meltdown of black families and neighborhoods and the takeover by hip hop culture.
