"Now, it's true that, as scientists, our basic job is to describe the world as it is. But I don't think that that's the only thing that matters. In fact, I think the reason why we're here, the reason why we think this is such an exciting topic, is not that we think that the new moral psychology is going to cure cancer. Rather, we think that understanding this aspect of human nature is going to perhaps change the way we think and change the way we respond to important problems and issues in the real world. If all we were going to do is just describe how people think and never do anything with it, never use our knowledge to change the way we relate to our problems, then I don't think there would be much of a payoff. I think that applying our scientific knowledge to real problems is the payoff."
