アルスター大学の名誉教授であるリチャード・リンは勇敢な研究者である。
２００２年、２００６年と彼は、フィンランドの政治学者ヴァンハネンと共著で、
世界の国々の国民の平均的な知能が、その国の豊かさ、民主主義の度合い、
大学進学率、平均寿命などと０．５から０．７の送還を持つことを主張しているのである。
知能の遺伝率は相当に高く、Jensenなどの研究では、０．５以上ではある。
とすれば、大きな国民所得の格差などはその国民の知能水準に依存するという結論になるだろう。
もちろん、政府が社会主義ではどうしようもないが、そういった制度の違いを超えて、５００年前からの
データを使っても、相関係数が０．２程度、これはわずかではあるが、しかし完全に有意であるのは驚きだ。
これはいかなる経済学者にとってもタブーとして、触れてはいけない命題だったのだが、
やはり経済学以外の学者が始めたというのは興味深いことだ。
さて、小生はAmazon, comの書評に以下のような公開質問を世界の研究者にした（つもり）なのだが、
どうなるだろうか？
Lynn and Vanhanen’s claim that national average IQ is a most reliable predictor of various national quality of life is, in my opinion, that most plausible hypothesis in social sciences presented ever. Chinese economic progress after their adoption of capitalism as the factory of the world in the 21st century may well be one of the impeccable evidence. It is truly amazing that no professional economists so far have advanced this simple idea even though I know the existence of the blizzard of PC movement in the U.S.
One thing that I personally would like those who understand IQ controversy fully to think about is that, although East Asians have 105 IQ points on average, most of modern math and sciences have been developed by Europeans, who have 100 IQ points on average. There seems to exist a small inconsistency here. My guess is that, as the former U. Penn professor, Vining reported on a paper (which I forgot for exact time and place unfortunately), European Caucasians have higher variance as for IQ points among other psychological traits. Therefore, super-smart people tend to be born among Europeans and hence modern civilization has been advanced in Europe. I think this is still articulately shown in the number of Nobel laureates and Fields medalists
One more puzzle is the Indian national IQ points estimated around 80. Other things aside, this is somewhat bewildering to me that Ramanujan and other famous mathematicians and statisticians are Indians when we look at the field. Also many Indians, including famous Adobe founder, are known to be very good at computer programming which consist mostly of dense logic.
Can someone suggest anything on this? BTW, although I am genetically Japanese living in Japan, I love scientific truth and hate nationalism. Thank you in advance.
