David B. Wilkins, A Systematic Response to Systemic Disadvantage: A Response to Sander, 57 STAN. L. REV. 1915, 1917 (2005). And before blacks were admitted to law school, few worried that the white men at the bottom of the class were outmatched by their peers. Still, that half of all black students are in the bottom tenth of the class at least suggests that law schools may not be providing as good an education to their black students, for whatever reason. Even if this is not the case-again, some group of students has to be at the bottom of the class-law schools should think carefully about the stereotypes that this fact perpetuates.

As a self-proclaimed math geek, I hear confessions from many people about prior math classes. The mantra I'm just not good at math may be, at least in part, a widely held, culturally accepted disengagement with the process of learning mathematics.

J. 345, 362 (2003) (noting that self-images of mathematical ability [were] overwhelmingly negative and that this contributed to less willingness to engage with mathematics).

Stereotype threat is a term used to describe the phenomenon of minority groups performing more poorly than expected because of the stereotype that the minority groups will, in fact, perform poorly. See generally Claude M, Steele & Joshua Aronson, Stereotype Threat and the Intellectual Test Perform ance of African Americans, 69 J. PERSONALITY & SOC. PSYCHOL. 797 1995, As a concrete example, black students taking the SAT hear and internalize the stereotype that blacks do not do well on the SAT. They worry about the prospect, they get angry at the stereotype, and they feel that others expect them to do poorly. All of these factors distract them from the task at hand-taking the SAT-and therefore make optimal performance more difficult

Several readers of drafts of this Essay commented that such treatment would simply make them work harder. I have two responses to this suggestion. First, as educators, we should not condone a discriminatory culture because it makes students work harder or somehow instills values of perseverance. Second, as an individual student, I certainly learned from this experience and did not allow such treatment to affect my performance in subsequent classes. The underlying point, however, is that the educational environment should be created in such a way as to facilitate learning for all students, without creating barriers to learning based upon arbitrary factors such as gender or race

I recognize that there are many measures of law school achievement; grades, participation in moot courts, law review, trial teams, and other activities are just a few. The only measured achievement gap upon which I focus is grades; this is the only measured achievement within law school. I focus on grades primarily because of the common perception that grades are the primary determinant of job prospects after law school and because it is a very stark statistic that I believe deserves some attention

Some critics acknowledge the troubling aspect of the data but suggest that Sander's remedy of dismantling affirmative action is inappropriate. See Ian Ayres & Richard Brooks, Does Affirmative Action Reduce the Number of Black Lawyers?, 57 STAN. L. REV. 1807, 1808-09 (2005). Indeed, just because the legal academy may be doing a poorer job of educating its black students does not mean that the legal academy should get out of the business of doing so.

Sander's critics do not always defend affirmative action explicitly, but in evaluating Sander's methodology and results, it is clear that his critics take as a baseline the use of affirmative action. By doing so, Sander's critics require that any deviation from current affirmative action policy be justified by empirical proof. Even the title of the response of Chambers et al., The Real Impact of Eliminating Affirmative Action, emphasizes that affirmative action is the baseline from which there might be a policy change.

As I use the phrase, credentials or student credentials is a broad term encompassing any information known to admissions officers that might impact law school performance. LSAT and UGPA are two objective measures of student credentials, but other variables, ranging from difficulty of undergraduate program to maturity level to family support network, may impact law school performance. Consistent with my broad definition, the phrase student credentials encompasses all of these variables. In this discussion, I assume that one can accurately measure student credentials, although the empirical tests I report use only the imperfect measures of LSAT and UGPA. It is, however, theoretically possible to measure student credentials, even when broadly construed to include any attribute that will affect student performance. See infra Part III.B

Thus, many researchers compare black students who attend different school types, confounding different school cultures with mismatch, and, more troubling, white students with black students at the same school type. This latter comparison is based upon the demonstrably false assumption that white and black students with similar credentials attend different schools. While perhaps true on average, making this comparison confounds mismatch effects with discrimination effects

Statistical models can contain main effects and interaction effects. Main effects estimate the average performance effect for the group. For example, the main effect of school type will estimate the average graduation rate for each school type separately, and the credentials main effects will estimate the average performance boost a student receives based upon a boost in their credentials. Without interaction terms, however, the model would assume that the effect of credentials upon performance and the effect of school type on performance is simply additive; the two do not interact at all. For example, students in a highly-ranked school would receive the same the same performance boost from being at that school whether their credentials suggested that they were mismatched or not.

Because stereotype threat may be counteracted by simple statements suggesting that the test administered is unbiased, in some situations stereotype threat may appear to be a school-specific phenomenon, as some schools counteract the threat while others do not.

Recall that student credentials are attributes that affect student performance about which admissions offices have information. See supra note 25. Because applications for admission cannot include every possible attribute that might affect student performance, there will always be unmeasured attributes that affect student performance, that is, unmeasured credentials. Many of these will be soft variables: ability to work with others well and to persevere, familial support, familiarity with the law and lawyers, etc.

I have also performed the analysis with the original school type structure. The results from Part II are substantially similar; the results from Part I differ in two ways: first, the racial barriers tests demonstrate that each of the six school types have different average school cultures that affect minority students differently; second, the mismatch tests show no discernible pattern (either mismatch or reverse mismatch), likely because of the overlap in school ranks across school types. Tables for this alternative analysis are available from the author upon request.

To put LSAT and UGPA on the same scale, Sander first normalizes both variables, so the full function is: Credentials = 0.6 times; 1000 ×(LSAT - 10)/38+0.4×1000 × UGPA/4 Sander, supra note 5, at 393. My formula differs from that in Sander's article because Sander uses normalized values for LSAT and UGPA; the formula above does the normalization as well,

The β coefficients are estimated via logistic regression. The function allows significantly more flexibility than a linear or quadratic function. Specifically, it allows for very low credentials-those most at risk of being mismatched-to affect performance differently than all other credentials. This is the purpose of choosing at least a cubic polynomial: I investigated higher-ordered polynomials of degree 4 or 5, but found little additional benefit from these more complicated models. I also investigated how different my results would be if I used the academic index that Sander created; the results are substantially different. Using the less flexible form significantly underestimates the black student graduation rate and bar passage rate, as compared to the more flexible form.

Tables IA through 3B all report results from logistic regressions of a performance measure on student credentials, type of school, race, race * school type interactions, and student credentials * school type interactions. The A tables report results relevant to the mismatch theory, and the B tables report results relevant to the race-based barriers theory. Because of the large number of interaction terms for each table. I report the significance level of a joint test whether or not the interactions are statistically significant. For the A tables, this is the mismatch theory test; for the B tables, this is the race-based barriers test. In addition, rather than report each parameter for the 27 (school type * credentials) interactions and the 12 (school type * race) interactions, I provide the change in estimated successful performance relative to a baseline group of students who are described in each pane

For example, the first three rows of Table IA report the change in graduation rate for students at Historically Black, Lowrange, and Top 30 Schools, respectively, as compared to a baseline of students who matriculated at Midrange Schools, whose credentials are in the fifth percentile of the entire data set. These "baseline" students have an 83.3% chance of graduating from law school.

Again, because of the serious limitations in the data described above, I do not want to overclaim. The results suggest that the mismatch and discrimination theories are likely in evidence, but they cannot demonstrate conclusively that either theory affects law students' graduation rates.

A p-value measures how likely it is that the observed difference between the model estimates and a null hypothesis can be explained by random variation in the data. Traditionally, values less than 0.05 (on a scale of 0 to 1) are considered statistically significant; values between 0.10 and 0.05 are considered marginally significant. For Table 1A, the null hypothesis is that mismatch theory does not affect student graduation rates

Specifically, the difference is 28 percentage points for those in the fifth percentile of student credentials, and 20 percentage points for those in the tenth percentile. In a logistic regression, the change in probabilities is not additive, because of the logistic functional form. Thus, to compare Historically Black Schools to schools other than Mid-range Schools the baseline, one has to return to the underlying coefficients of the model

In addition to a small sample size, the data on salaries has a low response rate. In all, approximately 3251 of 27,458 students responded, for a response rate of 11.8, This means two things: first, there is significantly less power to determine differences (particularly for those groups that are a relatively small percentage of the entire data set, and second, that the results are further suspect because of the possibility that the data are missing non-randomly that is, that a student's characteristics-like race or school type-would affect their probability of answering the salary question in the first place

However, this result may be in part due to the greater diversity in these schools, differentially leading to higher white student performance. This is mere speculation; research into different law school cultures and how they affect student performance is outside the scope of this Essay.

In their critique of Sander's analysis, Chambers et al. make the point that these assumptions are unrealistic. Chambers et al., supra note 21, at 1888. Any bias, however, will tend to underestimate the negative effect on black students of getting rid of affirmative action; it is highly unlikely that more black students will apply and matriculate at law schools absent affirmative action.

In essence, affirmative action becomes the treatment that minority students receive; in the thought experiment that one would optimally perform, one would assign individuals randomly to different school types. This would be akin to a particular medical intervention in a clinical trial, See Rubin, supra note 27, at 689 discussing general treatments in the context of both randomized experiments and observational studies

Chambers et al. point out that the 14.1% figure, based on 2001 data, is a very low percentage compared with other years. Between 1991 and 2004, the percentage of black applicants who would not be accepted at any law school absent affirmative action ranged from 9.1% to 52.5, Chambers et al, supra note 21, at 1861 tbl.1. In addition, the assumption that the bottom 14.1% of applicants would not be accepted is not completely realistic. Based in part on the randomness of the application process, and in part on unmeasured credentials, some individuals with higher LSAT and UGPA scores will not be admitted, while some within the bottom 14.1% will be admitted to some law schools. Both of these assumptions, like the other assumptions I make regarding the model, would tend to underestimate the negative effects of getting rid of affirmative action, and therefore provide a conservative estimate of what the change would entail

The bootstrap is an extremely useful statistical tool that allows one to calculate standard errors (as well as other quantities of interest) non-parametrically, that is, without making restrictive parametric assumptions, such as the assumption that the data follow a normal distribution. It is particularly useful in complicated models where small deviations from initial parametric assumptions can become magnified into large errors in measurement. See BRADLEY EFRON & ROBERT J. TIBSHIRANI, AN INTRODUCTION TO THE BOOTSTRAP (1994) for details about the bootstrap procedure for determining standard errors

The calculations of the p-values and standard errors of the difference also account for the fact that the two numbers are correlated because the two simulations use the same bootstrap sample and the same underlying models of student achievement. The standard error of the difference between any two values in the table is provided by the following formula: s.e.(X- Y, √ σx2-2ρxyσ xσy, σy 2 where σx is the standard deviation of X, σy is the standard deviation of Y, and ρxv is the correlation between X and Y. See DENNIS WACKERLY ET AL, MATHEMATICAL STATISTICS WITH APPLICATIONS 228 thm.5.12 5th ed. 1996

This range represents a 95% confidence interval for the percentage loss of new black lawyers absent affirmative action. This means that if one were to rerun the entire experiment with new data one hundred times, on average ninety-five of those times the true value of the percentage decline in new black lawyers would be within the confidence interval estimated. See MCCLAVE ET AL, supra note 84, at 255

The absolute number of lawyers in Sander's model is larger because my model predicts bar passage for a subset of the LSAC data-respondents whose race is known-while Sander's model predicts bar passage for the larger group of all respondents. Because neither model predicts the total number of lawyers outside the LSAC sample, what is most relevant is the percentage change in numbers, rather than the absolute numbers.

In order to compare my results with those of Sander more directly, 1 simulate Sander's grid model as well. Due to the random variation in the simulation, I estimate a slightly larger increase in the number of new black lawyers absent affirmative action-9.1%, specifically. By simulating the model several times, I am also able to estimate a 95% confidence interval for this number: 9.1% ±3.8%. See supra Table 7.

Because of the low response rate on the salary question in the data, the error in the estimates, and consequently the confidence interval, is quite large. It is still clear, however, that the model predicts a statistically significant drop in the number of black law graduates who obtain well-paying jobs, which is also substantively important

Ho, Scholarship Comment, supra note 21, at 2000-02. Post-treatment bias is the bias that results from including in a regression variables that occur after the treatment began (post-treatment variables) and therefore may have been affected by the treatment. In Sander's case, the main culprit is law school grades, which are determined after the treatment of matriculating at a specific school type.

U.S. DEPARTMENT OF COMMERCE, RESEARCH OPPORTUNITIES AT THE CENSUS BUREAU, DIR/01-RFP, at 4 (July 2001), available at http://www.census.gov/prod/2001pubs/dir-01rfp.pdf Care must still be taken, however, to protect confidentiality in the final product. In one extreme example, the United States Department of Justice issued a report with over 450 tables of information about less than 1000 observations. This level of detail allowed an entrepreneurial researcher to reverse-engineer the tables in order to reconstitute the private data.
