First, we chart the development of the legal argument over affirmative action, in order to show how data on campus attitudes became central to a debate that once centered on evidence of the practice or effects of prior societal discrimination…</p>
<p>The argument that racial diversity is beneficial for all students, or the campus community at large, can be operationalized as a set of hypotheses that increasing black student enrollment (enrollment diversity) in predominantly white student bodies will produce a better educational environment in general, greater attention to and satisfaction with the quality of education, and better relations between white students and students of color [heretofore referred to as the diversity model]…</p>
<p>Results…</p>
<p>The top row of Table I shows small but statistically significant relationships (p<.01) between enrollment diversity and four of the six dependent variables–student satisfaction with their university experience, the quality of their education, their assessment of student work efforts, and their complaints of having personally experienced discrimination. In every case, however, the significant correlations were in the direction opposite those predicted by the diversity model. As the proportion of black students enrolled at the institution rose, student satisfaction with their university experience dropped, as did assessments of the quality of their education, and the work efforts of their peers… </p>
<p>Although the correlations were low, it is unusual for hypothesis testing of such a clearly specified model to produce a reversal of signs on all operational measures that produce statistically significant correlations. [Black enrollment ranged from 0 to 43 percent; historically black college students were excluded from the analysis.]</p>
<p>The same pattern held for the faculty sample’s evaluation of the educational milieu. Among faculty members enrollment diversity was negatively related to perceptions of the quality of education, the academic abilities of students, and the work efforts of students, with all correlations again significant at the .01 level. However, assessments of race relations were in line with the model’s predictions…</p>
<p>This bifurcation of evaluations between educational ratings and minority relations appeared among administrators as well. Like the students, administrators perceived declining educational quality and students’ skill as the proportion of black enrollment rose; like the faculty, [and unlike the students] they also perceived less racial discrimination and better treatment of minority students…</p>
<p>Two of the items, satisfaction with university experience and unfair treatment, are behavioral self-reports…</p>
<p>In the student sample both self-reports as well as two of four institutional characterizations produced statistically significant findings that were the reverse of those predicted by the diversity model. This weakens the possibility that their perceptions of the institution represent ‘third person’ effects at variance with their own personal experience…</p>
<p>Enrollment diversity was positively related to experiencing unfair treatment after the effects of all those variables were controlled. That is, enrollment diversity contributed to the incidence of encounters perceived as discriminatory rather than decreasing them, after controlling for the effects of a student’s membership in a historically victimized group…</p>
<p>Enrollment diversity was inversely related to faculty satisfaction with the quality of education, the work effort of the student body…</p>
<p>We found that much of the data supporting the diversity model suffers from methodological defects, which range from poor item formulation [survey questions] to interpretive problems linked to selective recall and a social desirability response set. Further, there are inherent limitations in research designs that adduce success or failure of a policy intended to affect behavior simply by asking the affected parties whether they think it is working. (This is especially true when the policy is presented as a moral imperative that is central to the mission of the institution [Bradley Effect?].) For example, one wouldn’t evaluate the success of a program to reduce teenage pregnancy on the basis of an attitude survey of teenagers, rather than from epirical data on changes in the pregnancy rate. [Their method was to ask non-controversial questions about perceptions and experiences and correlate them with enrollment diversity.]…</p>
<p>When student evaluations of the educational and racial atmosphere were correlated with the percentage of black students enrolled at a college or university, the predicted positive associations of educational benefits and inter-racial understanding failed to appear. A pattern of statistically significant associations appeared, but it was in the opposite [i.e. negative] direction from that predicted by the diversity model. The results were clear and consistent with regard to the measures of the educational milieu. They were echoed by equally consistent patterns of responses among faculty and administrators.</p>
