Brains, brawn, brides: A study performed at four British universities makes a correlation between IQ and prospects for marriage. After studying 900 men and women, starting when the subjects were 11 and checking in with them at age 40, they found:

the schoolgirls with high IQs later witnessed a dramatic decline in their marriage prospects. But the brighter schoolboys found it easier to find a bride.

The results are borne out by evidence from psychologists that successful career women are struggling to find “interesting men” who are interested in them.

Relationship experts say professional men prefer to marry women “like their mum” who will provide the domestic support while they go out to work.

Women achievers, however, find it difficult to find men willing to sacrifice their careers to become house husbands.

...For boys, there is a 35% increase in the likelihood of marriage for each 16-point rise in IQ. For girls, there is a 40% drop for each 16-point increase.
