Jason Collins, over at Evolving Economics, notes that:
In response to my recent post on some statements by Garett Jones on immigration and IQ, Jones tweeted:
@jasonacollins If slightly-below-average member of high-IQ country moves to low-IQ country, both means can rise: A new export for China.
Typically, I was wearing my developed-country hat when I wrote the post, and was considering migration from a developing to a developed country. While migrant flow is typically in that direction, I missed the important implications for adoption of an IQ-focussed policy by a developing country. As Jones indicates, attracting slightly below average-IQ immigrants from China could boost the mean IQ of many developing states, and following his argument on IQ and trust, improve the country’s institutions and economic outcomes
