“When children earn stickers or candies by working as a team, they withhold their goodies from children who didn't help but share with children who did. This might not seem very friendly—it might even seem like behavior you should correct: sharing is caring after all—but from an evolutionary standpoint, it's mission critical.” — William Von Hippel
