This document comprises three presentations made on March 23 at a symposium sponsored by the Southern Regional Council focusing on Human Intelligence, Social Science and Social Policy. The first of the three parts of the document is the text of the principal presentation, made by Dr. Leon Kamin, Chariman of the Department of Psychology at Princeton University. The presentation first summarizes findings of his extensive research into the original studies on which some American social scientists have based writings which at least question whether environment has any effect on IQ test scores--suggesting that heredity may be the determinant. The second part of the document is the text of a presentation by Ms. Winifred Green, director of the Atlanta-based Southeastern Public Education Program of the American Friends Service Committee. The presentation argues that grouping reinforces the effects of years of discriminatory treatment in the education of black children--locking them into classroom situations where curriculum, materials, teacher expectation and the resulting stigmas and hopelessness are the same as, or some predict worse than, the days of separate but unequal schools. The third part is the text of Dr. Kamin's afternoon presentation on the history of the use in the United States to support repressive public policy. (Author/JM)
