Mike Nova comments: It means, that ethnic groups sharing geological proximity also share collective ("ethnic, national, aggregate") personality traits; most likely because they share common genetic pool and genetic traits (due to intermarriage). Which is another indirect proof that "national characters" are genetically, biologically determined (although socially "constructed")

Personality and place

This paper examines the distribution of national personality dimensions in geographical space. The relationship between geographical location and aggregate personality in a wide range of nations is quantified using spatial autocorrelation, and it is found that the personalities of nations that are geographical neighbours are more similar than those that are far apart. The five factors of both the Revised NEO Personality Inventory (NEO-PI-R) and the Big Five Inventory (BFI), all show a significant degree of spatial organization. The personality factors most strongly associated with geographical location are NEO-PI-R extraversion and BFI conscientiousness; both vary with position around the globe about as much as the physical climate. These findings support previous research suggesting associations between aggregate personality and geography, and imply that the sources of variation in national personality are themselves geographically organized.
