Funny story I remember from the first day of my first psych class: The teacher asked us to imagine a coin-flipping contest held in the main quad. Everyone in the school was asked to attend. Every 10 minutes there was a whistle, and you had to flip your coin. Heads, you were still alive, tails you left. After a little more than half a dozen rounds, we were down to the last 64 flippers. These were clearly the most talented flippers in the school. But when they flipped this time, some of them weren't 100% focused, and only 32 remained. Of those 32, it turned out some just weren't as good as we thought, and only 16 remained. In the round of 8, the crowd noise pumped up about half, and only those four remained. The pressure finally became too much for two of them, and we were down to the final two. But one of them just wanted it more, and he was the only one to flip heads, thus proving scientifically that he was the most skilled coin-flipper in the school.
