The limitations of the study are those characteristics of design or methodology that influenced the application or interpretation of its results.
Whiteness. To the extent that a significant number of minority students reported their race as "Unknown," the percentage of White students will be skewed upward.
Excess Whiteness. When comparing schools for Excess Whiteness, it was assumed that all schools drew from the national pool of applications. This meant that the applicant pool for all schools was 68% White. To the extent that a school is a truly regional, state, or local school, then the percentage of total Whiteness when compared to the availability of applicants could be skewed. The same is true for state and regional comparison. To minimize the impact, all three measurements (national, state, and regional) were added together.
For those who object to the methodology here, based on the idea that it does not consider the pool of qualified applicants, see my essay on the "LSAT and Racial Discrimination" and my article “ Incompetent Legal Education” As practiced in most law schools, the law school admission process is not an issue of who can graduate from law school and become a competent lawyer. It is mostly a cherry-picking exercise among applicants who would be being good lawyers if legal education would educate instead of sort.
