ADVICE: Don’t Marry An Overeducated Woman.
IQ and credential fetishists love to write about the low rate of divorce among the overeducated, but what they always fail to grasp is that a big reason for this is the decrease in sexual market options among the high IQ that accompanies their later in life marriages. So yeah, you get a more faithful wife with crows’ feet and a saggy butt. Lack of options = stability. Worth the trade-off?
If anything, it looks as if the best bet, if you want to avoid divorce, is to 1. skip marriage altogether or 2. marry a woman who will be a stay at home mom and won’t make more money than you. That means, in practice, avoiding women with masters or doctoral degrees, since it is likely they will have upper quintile incomes.
