– small families, either nuclear or stem
– higher average iqs than outside the line
– the highest concentrations of human accomplishment in europe
– more democracy
– greater civic-mindedness or orientation towards the commonweal
– generally low perceived corruption
– high individualism
– and low homicide rates in the 19th century
