<p>I don’t think there’s much of a “bias.” It’s just that Yale dominates in all fields - in Loren Pope’s widely-published analysis, almost 4 times more than Stanford.</p>
<p>According to Gary Glen Price, of the University of Wisconsin Education Department (and not a graduate of Yale):</p>
<p>“Schools do have distinctive strengths and institutional cultures. Overnight stays give some glimpse of this. So do the post-graduation activities and accomplishments of alumni. For instance, the relative proportion of Williams alumni who were corporate executive officers (CEOs) of Standard & Poor companies in 1990 was 1.6 times greater than the proportion of Amherst alumni and 4.6 times greater than the proportion of Swarthmore alumni. Among CEOs of Fortune 500 companies and Service 500 companies in 1990, the proportion of Amherst alumni was 1.25 times that of Williams alumni; Swarthmore had too few to be included in Fortune magazine’s analysis (Yale had the highest per capita rate of CEOs; Princeton was second). In Loren Pope’s analysis of the percentage of alumni featured in the 1988-1989 edition of Who’s Who in America, all three schools were very high and closely clustered. Relative to Yale’s rate (the highest in the country, here set to 100), Amherst was 56.5, Williams was 54.2, and Swarthmore was 48.2; among the notable schools lower than all three were Dartmouth (44.8), MIT (43.3), Stanford (29.5), Penn (19.1), and Duke (14.9). The proportion of Swarthmore alumni who earned PhDs in science, math, or engineering during 1985-1990 was double that of Amherst and Williams; in other PhD fields, Swarthmore’s proportion was 1.5 times Amherst’s and 2.4 times William’s. Swarthmore counts several Nobel laureates among its alumni, whereas Amherst and Williams count none.”</p>
