When computers came along, I felt for the first time that I had the proper tools for the kind of theoretical work I wanted to do. So I moved over to that, and that got me into psychology.

I tried to develop some theories that took account of the uncertainty in the world and the complexity in the world.

I started off thinking that maybe the social sciences ought to have the kinds of mathematics that the natural sciences had. That works a little bit in economics because they talk about costs, prices and quantities of goods.
