Yahoo! News: "NEW YORK -
Bill Clinton said he felt others' pain. But a new brain-scanning study suggests that when guys see a cheater get a mild electric shock, they don't feel his pain much at all. In fact, they rather enjoy it.
In contrast, women's brains showed they do empathize with the cheater's pain and don't get a kick out it.
It's not clear whether this difference in schadenfreude — enjoyment of another's misfortune — results from basic biology or sex roles learned during life, researchers say. But it could help explain why men have historically taken charge of punishing criminals and others who violate societal rules, said researcher Dr. Klaas Stephan."
Punishing children too, except for Eddie Murphy's mom and her shoe.
