(for those new followers, my position is that ‘circumpolar peoples’ -meaning north-baltic sea, han, korean, and japanese – have practiced both climate-selection, manorial-(economic)-selection, and the physical culling of malcontents for thousands of years. And that the ‘lesser peoples’ are burdened by not having experienced this eugenic process. … Worse, I argue that we may have passed ‘peak human’ and are in the process of devolution, because the Southern peoples compete by higher aggression, lower pro-social behavior, higher impulsivity, lower intelligence, and higher rates of reproduction. In other words, the problem is the distribution of abilities within races not necessarily racial differences themselves.)

–“It has become increasingly evident that human populations have different behavioral propensities and intelligence levels. Those who have adapted to the harsh northern climate worldwide are taller, more intelligent, more pro-social, less crime prone, and exhibit less fertility. This is said to be due to the more cognitively demanding long winter season (Lynn, 2006 and Lynn, 2008). In a similar and more speculative vein, the differential r/K theory (Rushton, 1988 and Rushton, 1994) predicts that a more demanding cold climate has induced more intelligent and pro-social personality in general.

While these differences in intelligence and behavioral traits were reported mainly with respect to racial categories in the twentieth century (Herrnstein and Murray, 1994 and Rushton, 1994), even finer gradients of these personality traits from all over the world have been reported in the twenty-first century (Lynn, 2006, Lynn, 2010, Lynn, 2012, Lynn and Vanhanen, 2002, Lynn and Vanhanen, 2006 and McDaniel, 2006).

Since nation states like Italy and Spain exhibit north–south differences in their behavioral propensities in the above expected directions, it is natural to expect the same gradients in other parts of the world. In Japan, although casual observation sometimes admits that regional behavioral and IQ differences result in relatively poor economic performances in the south, there exists only one paper suggesting regional IQ differences on Okinawa, the southernmost region (Agarie, 1959). Serious inquiry on this topic has been effectively prohibited due to the political correctness and self-censorship in Japanese academia. Since various kinds of IQ tests such as the WISCor Progressive Matrices were no longer being conducted after the 1970s, this paper examines this conjecture by utilizing national achievement test scores from Japan’s 47 prefectural populations.

Additionally, income returns to IQ premium are calculated at the prefectural level so that it could be included in the database of the robust IQ/income relationships reported to date (Jencks, 1972, Herrnstein and Murray, 1994, Murray, 1998, Murray, 2002, Altonji and Pierret, 2001, Zax and Rees, 2002 and Hanushek and Woessmann, 2008).”—-
