Responds to comments made by Pipes and Kuncel and Sackett on the current authors' original article (see record 2006-01690-003). The current authors respond to the various points raised in the commenting articles, and suggest that diversity is a compelling interest and affirmative action is one means of achieving it. They stand by their original challenge, with the caveat that they do recognize that some tests may predict certain educational outcomes with similar reliability across diverse populations. They suggest that an increase in diversity in psychology would promote a robust exchange of ideas and would be of value to all.
