The failure of Lewin's immediate intellectual descendants to apply dissonance theory, with its obvious debt to Lewinian tension-system theorizing, at a time when a crucial issue of the day—racial integration of schools and neighborhoods—constituted an immense exercise in forced compliance, and hoped-for attitude change, is especially puzzling. (Only later did several prominent Lewinians—Elliot Aronson and Phil Zimbardo, along with Morton Deutsch and Hal Gerard—turn their attention to the analysis of important social issues like school integration, social isolation, alienation, and violence.)
