More than 200 students were shown pictures of men and women of varying attractiveness, then offered a chance to win money: If they rolled double digits on dice, they could either accept a check for between $15 and $35 the following day, or wait a week to eight months and get even more money — $50 to $75.

After viewing pictures of highly attractive women, the male students were more likely to choose the immediate cash rather than wait a day for the extra cash.

But the female students weren’t swayed by images of hot guys. They chose the larger reward.
