Child-rearing practices shape national motivations that drive political and economic rise and fall.

Evidence

Macroscientific studies using conglomerates (nations, epochs, etc.) are rarer than microscientific studies. A macroscientific study transitional between the 1940s and 1950s political personality era and the 1960s and 1970s political attitudes era is McClelland’s (1961) research on how societies’ child-rearing practices affect and are affected by their citizens’ achievement, power, and affiliation motivations, and how these in turn affect the rise and fall of the societies’ political dominance, their cultural influence, and their economic affluence. McClelland’s motivational mediators have elements both of the first era’s personality and this second era’s attitudinal mediators. — John T. Jost and Jim Sidanius, Political Psychology, 373
