The Zero-Sum Argument, Legacy Preferences, and the Erosion of the Distinction Between Disparate Treatment and Disparate Impact

In a complaint recently filed with the Department of Education, a group of civil rights organizations allege that Harvard University's legacy preference unlawfully discriminates against minority applicants in violation of Title VI of the Civil Rights Act of 1964. In response, the Department of Education has opened an inquiry. Interestingly, the Complainants deploy the argument made by Chief Justice Roberts in Students for Fair Admissions, Inc. v. President & Fellows of Harvard College (SFFA) that “[c]ollege admissions are zero-sum,” and so, a “benefit provided to some applicants but not to others necessarily advantages the former group at the expense of the latter.” Using this argument, the complaint alleges that a legacy preference cannot simply be viewed as a benefit to the relatives of alumni; it must simultaneously be viewed as a detriment to applicants who have no relation to alumni, a group we might call “non-legacies.” Because minority applicants are disproportionately represented among the non-legacy group, the legacy preference has a disparate impact on minority applicants. The complaint goes on to argue that the preference for legacies has no educational benefit, making this disparate impact unlawful. 

I am not sure that Complainants need the zero-sum argument to state a claim for disparate impact, but it certainly strengthens their argument, both logically and rhetorically. What I want to explore is whether Complainants could have done even more with the zero-sum argument. In particular, I am interested in exploring whether the zero-sum argument implicitly erodes the firm doctrinal distinction between disparate treatment and disparate impact, or, at the least, exposes an important conceptual linkage between the two forms of discrimination.

In SFFA, Chief Justice Roberts asserts that under current doctrine race can never be a “negative.” In his view, “our cases have stressed that an individual's race may never be used against him in the admissions process.” None of the other Justices or litigants take issue with that assertion. Rather, Harvard College and the University of North Carolina (“UNC”) claim that their admissions policies do not make race a negative; it is a plus for some applicants in some contexts but never a minus. Chief Justice Roberts finds this argument “hard to take seriously” because university admissions are “zero-sum.”11 In his view, a plus in the admissions process given to Black and Latinx students, for example, is a minus to white students and others not eligible for this benefit. To put the claim in a formal fashion, we might restate it as follows: in contexts like admissions, where the number of positive outcomes is limited, considering Trait X as a plus for Applicant A necessarily requires the decision-maker to treat the lack of Trait X as a minus for Applicant B. Let's call this the Zero-Sum Claim. 

In what follows, I examine the Zero-Sum Claim in the context of the recently challenged legacy preference and explore the implications of its underlying logic for the doctrinal distinction in U.S. anti-discrimination law between disparate treatment and disparate impact.
