Political correctness drives talented white men out of many areas. Steve Sailer pointed out in his 2011 review of the movie Moneyball that:
Smart middle-aged white guys really like baseball statistics. Sabermetrics provides men with a sheltered playpen in which to study nature and nurture with little risk of being called sexist or racist.
Political correctness makes analysis of too many areas a career killer (as I found with global warming):
The bigger question is whether smart quantitatively-oriented white guys devote too much of their time to thinking hard about sports numbers (for which they are unlikely to become the object of Two Minutes Hates) rather than more important real world issues (at the risk of having their careers destroyed). …
There’s a definite crimestop problem where almost anything could get you in trouble these days, leading to smart guys tending to go into playpens like sabermetrics where they won’t get Watsoned.
