The Science Behind College-Football Helmet Stickers | Playbook: "The researchers found that when the mug was the prize, the men in the group — but not the women — fought harder to win, so they more readily threw in all their cash during the game, vying for the highest possible ratings from their teammates. And when competing for the mug, the males cooperated more with each other, instead of plotting and scheming against the rest of the group.

Pan thinks the findings show that the males viewed the mug as a displayable trophy to the rest of the group, and their desire to win the affection of their peers spurred them to shift their behavior away from self-interest toward a strategy that was better aligned for team success."
