610 Importance of mentorsposition at ETS in Princeton, New Jersey, where I also taught part-time atPrinceton’s young Statistics Department, which renewed my friendship withTukey; between the two positions, my annual salary was more than twice whatI could be offered at Harvard to stay there as junior faculty.50.5 The decade at ETSThe time at ETS really encouraged many of my earlier applied and theoreticalconnections — it was like an academic position with teaching responsibilitiesreplaced by consulting on ETS’s social science problems, including psychologicaland educational testing ones; and I had the academic connection atPrinceton, where for several years I taught one course a year. My ETS boss, AlBeaton, had a Harvard Doctorate in Education, and had worked with Dempsteron computational issues, such as the “sweep operator.” Al was a very niceguy with deep understanding of practical computing issues. These were greattimes for me, with tremendous freedom to pursue what I regarded as importantwork. Also in those early years I had the freedom to remain in close contactwith Cochran, Dempster, Holland, and Rosenthal, which was very importantto me and fully encouraged by Beaton. I also had a Guggenheim fellowship in1978, during which I spent a semester teaching causal inference back at Harvard.A few years before I had visited the University of California Berkeley fora semester, where I was given an office next to Jerzy Neyman, who was thenretired but very active — a great European gentleman, who clearly knew thedifference between mathematical statistics for publishing and real statisticsfor science — there is no doubt that I learned from him, not a mentor as such,but as a patient and kind scholar interested in helping younger people, evenone from ETS.Here’s where Julian Jaynes re-enters the picture in a major way. We becamevery close friends, having dinner and drinks together several times a weekat a basement restaurant/bar in Princeton called the Annex. We would havelong discussions about psychology and scientific evidence, e.g., what makesfor consciousness. His knowledge of history and of psychology was voluminous,and he, in combination with Rosenthal and the issues at ETS, certainlycemented my fascination with social science generally. A different style mentor,with a truly eye-opening view of the world.
