This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Dr. David Ewoldsen studies the psychology video games at Ohio State, and in multiple studies his lab has found that cooperative-competition gaming increases pro-social effects in people. The increase in cooperation and trust not only occurs during gameplay, but also afterwards. It is not the content of a game that matters; what matters is how you choose to play the game.
