The extraordinary decline in the cost of sequencing a whole human genome, from $10 million in 2008 to $1,400 by late 2015, means that in the coming years science will almost certainly be able to answer the Charles Murray question: Are some of the gaps in average IQ among the races at least partly genetic?
It’s past time for public intellectuals to seriously ponder the implications of either answer: yes or no.
Last week, I discussed what it would suggest for public policy if Murray turned out to be wrong. This week, I want to consider what is likely to happen if Murray turns out to be right.
Behavioral genetics is a science that is speeding up. Two weeks ago, The New York Times headlined:
We also provide evidence that variants associated with several traits, including height, educational attainment, and self-reported unibrow, have been influenced by polygenic adaptation in different human populations.
Also this week, James Thompson summarized Davide Piffer’s (so far not peer-reviewed) analysis of racial differences in IQ and genes here.
