George Mason U. economist Bryan Caplan, author of The Myth of the Rational Voter: Why Democracies Choose Bad Policies, asks on EconLog:
I've often heard opponents of Latin American immigration complain that they're lowering our average IQ. ... Question: [If] this is the real concern, why not just advocate additional "compensatory" immigration from high-IQ countries like
This logic could be used equally well in many other situations:
Used Car Salesman: "You should buy this red car."
Prof. Caplan: "But this red car is a piece of junk."
Used Car Salesman: "Well ... that blue car over there is in great shape. Hey, you could buy both the bad red car and the good blue car and that would be kind of like having one average car!"
Prof. Caplan: "Wow, that's terrific thinking ... I'll take both! Where do I sign?"
Prof. Cowen: "Which applicant should we hire for the Assistant Professor job in our Econ department: the really dumb guy or the really smart guy?"
Prof. Caplan: "Tough question, tough question ... I know! Let's hire both!"
Why is it that smart economists' IQs drop 50 points when they try to think about immigration?
