Divorce Predictor #11: You are of “below average” intelligence.

According to the Delaware-Johns Hopkins Project for the Study of Intelligence and Society, a person of “below average” intelligence is 50 percent more likely to be divorced than one of “above average” intelligence. Spouses with IQs of 100 have a 28 percent probability of divorce in the first five years of marriage, as compared to a 9 percent probability for those with IQs of 130 or higher.
