I'm a professor of psychology, economics and management at Yale. The thing that I'm interested in, and that I spend pretty much all of my time thinking about, is cooperation—situations where people have the chance to help others at a cost to themselves. The questions that I'm interested in are how do we explain the fact that, by and large, people are quite cooperative, and even more importantly, what can we do to get people to be more cooperative, to be more willing to make sacrifices for the collective good?
There's been a lot of work on cooperation in different fields, and certain basic themes have emerged, what you might call mechanisms for promoting cooperation: ways that you can structure interactions so that people learn to cooperate. In general, if you imagine that most people in a group are doing the cooperative thing, paying costs to help the group as a whole, but there's some subset that's decided "Oh, we don't feel like it; we're just going to look out for ourselves," the selfish people will be better off. Then, either through an evolutionary process or an imitation process, that selfish behavior will spread.
