Optimal distinctiveness theory

Social psychological theory

Optimal distinctiveness is a social psychological theory seeking to understand ingroup–outgroup differences. It asserts that individuals desire to attain an optimal balance of inclusion and distinctiveness within and between social groups and situations. These two motives are in constant opposition with each other; when there is too much of one motive, the other must increase in order to counterbalance it and vice versa. The theory of optimal distinctiveness was first proposed by Dr. Marilynn B. Brewer in 1991 and extensively reviewed in 2010 by Drs. Geoffrey J. Leonardelli, Cynthia L. Pickett, and Marilynn Brewer.
