I really don't care to wade into the unproductive morass of population-level IQ.

However, if you tell me that somebody's parents average an 85 IQ or have family histories of dyslexia, short-term memory deficits, schizophrenia or bipolar disorder, that's more predictive of how well they are going to do in life than what zip code they happen to reside in.
