One of the things I did was I decided to start a public opinion poll in 1976 for the presidential election. George Gallup’s organization is located in Princeton, and I got up the courage to go across the street and convince the Gallup organization to help us start a student poll, which we did. We involved a number of colleges up and down the East Coast, and launched a public opinion poll. That got me talking to a bunch of economics professors and political science professors and statisticians, and I just made some friends there, even though I was a math major doing other things. When it finally came to pass that I got into graduate school, and I didn’t quite know what I wanted to do, it seemed to me that all this, economics and worldly things, would be useful. It was something I ought to think about doing, so I went back and I saw them. I didn’t go back and see my math professors. I went back and saw people like Ed Tufte, a political scientist and statistician, and he pointed me to a few people in Boston. And they pointed me to the Harvard Business School, saying that was a place that would take an itinerant mathematician with good credentials, who didn’t necessarily know anything about economics, and would let them learn on the job. And sure enough, I don’t quite know why they did, so they gave me a position teaching managerial economics, and I didn’t know a thing about managerial economics but neither did the students. I was okay, and I learned faster than they did so it worked out just fine.
