Orientation and homicide rates across the 95 countries for which data are available is −0.325. The correlation between Indulgence and homicide is 0.25. Both are statistically significant. Long-Term Orientation and Indulgence scores are taken from http://www.geerthofstede.nl/research-vsm/dimension-data-matrix.aspx. Homicide data are the high estimates taken from International homicide statistics figures, United Nations Office on Drugs and Crime, 2009.
