Social science data and the APA: The Lockhart brief as a case in point.

The wisdom of the American Psychological Association's submitting amicus briefs to affect social or legal policy is questioned by an analysis of the brief claimed to be a strong example of the effective use of social science data in the public policy arena; namely, the APA brief (Bersoff & Ogden, 1987) inLockhart v. McCree (1986). The data relied upon in the brief do not appear to support the assertions based upon them, and other data are adduced to develop the critique. It is concluded that it is mischievous for the Association to address itself to the courts by generalizing a data base well beyond its useful limits: The adversarial and scientific methods of establishing truth are in several respects antithetical.
