Satoshi Kanazawa, a psychologist at the University of Canterbury in New Zealand, says marriage may tame geniuses.

Creative genius and crime express themselves early in men but both are turned off almost like a tap if a man gets married and has children, a study says.

The data remarkably concur with the brutal observation made by Albert Einstein, who wrote in 1942: “A person who has not made his great contribution to science before the age of 30 will never do so.”
