Asians (Chinese, Koreans, and Japanese) are supposed to have higher IQs (about 105 on average) than North Europeans (100), while sciences have been developed overwhelmingly by Europeans and their offshoots. Why Asians are lacking in scientific success might relate to two factors:
1. Low curiosity, which is expressed by lower Openness to experience (-.59 SD) as shown in various cross-cultural personality comparisons.
2. Collectivism, which is captured by various individualism-collectivism indices such as the Hofstede individualism index (IDV), or Hofstede and Triandis individualism index (about -2 SD). The genetic underpinnings for these traits, such as DRD4, 5HTTLPR, and OPRM1 have also become increasingly apparent.
To integrate these psychological traits, a “q” factor is constructed by factor analysis on measures of Openness and Collectivism, which are then correlated with variables measuring academic achievements and also student assessments. It is found that IQ scores coupled with “q” factor scores neatly predict racial scientific achievements and also world-wide student assessments.
