Most scientifi c discoveries have originated from Europe, and Europeans have won 20 times more Nobel Prizes than have Northeast Asians. We argue that this is explained not by IQ, but by interracial personality diff erences, underpinned by diff erences in gene distribution. In particular, the variance in scientifi c achievement is explained by diff erences in inquisitiveness (DRD4 7-repeat), psychological stability (5HTTLPR long form), and individualism (mu-opioid receptor gene; OPRM1 G allele ). Northeast Asians tend to be lower in these psychological traits, which we argue are necessary for exceptional scientifi c accomplishments. Since these traits comprise a positive matrix, we constructed a q index (measuring curiosity) from these gene frequencies among world populations. It is found that both IQ scores and q index contribute signifi cantly to the number of per capita Nobel Prizes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
