Would permitting polygamy lower the divorce rate?
Yes, according to evolutionary psychologist Satoshi Kanazawa. In the Big Think video above, Kanazawa suggests that western society's disapproval of polygamy is to blame for high rates of divorce.
"Humans are naturally polygynous," said Kanazawa. "Successful men have always acquired more mates, but we don't allow that in our society, so successful men are forced to divorce their previous wives who may be past the reproductive age in order to marry younger wives. If we allow polygyny -- if we allow some men to acquire multiple mates -- the divorce rate would go down dramatically."
Kanazawa, who's associated with the London School of Economics, has garnered criticism in the past for a May 2011 blog post on Psychology Today in which he suggested black women are "objectively less physically attractive than other women."
