It was a huge undertaking. And that was not all. We asked about political affiliation, left and right handedness, birth order, and whether participants were the children of parents who read to them at night. If we had an inkling that something might be important, we tried to find some way to add it to the soup. And as you'd expect, some of the issues raised by these questions turned out to matter a lot, others not so much, some not at all.
We got the results back in early 2008. But anyone who has ever conducted a large-scale survey knows that the initial data run was just the beginning. For the next half year, the data was processed, cut, interpreted, and reinterpreted. I continued to ask questions. Harris continued to look for the answers. Along the way, David Robinson, associate professor of finance at Duke University—an expert in the field of behavioral finance—volunteered to weigh in. He was insightful and tireless, and with his help, the story in the data revealed itself even more.
