What you play affects who you are

From this article on Massively, some researchers have shown a correlation between the type of character played in a game, and the behavior of that player after they are finished playing that game. Link

The setup : Students were asked to play a game, where students played as either Superman, Voldemort or a Circle.  Students were randomly assigned an avatar, and the game play did not change per character.  The game play involved fighting enemies.  Following the five minute game session, players were asked to participate in a blind taste test where they could provide either a chocolate sauce or a chili sauce to a future taste tester.  The students were also asked to rate the sauce poured from "Good/Pleasant" to "Bad/Unpleasant" on a scale. 

The results : The students who played Superman averaged double the amount of chocolate sauce poured, while the Voldemort players averaged double the amount of chili sauce poured relative to the Circle players.
