It's funny because the chart is the same if you're looking at: average intelligence, international homicide rates, child marriage for girls, rape rates, incest rates, first cousin marriage, birth defect rates, outdoor shitting rates, child mortality, child homicide, general homicide, average male height, starvation rates, life expectancy, access to drinking water (infrastructure), poverty rates, sexual abuse, HIV infection rates, recipients of foreign aid, birth rates, human trafficking, and lactose intolerance. I'm probably missing a few.
