Allport read conformity as marking a weak, authoritarian personality

Evidence

Allport also wondered what types of people are most likely to conform and what types to maintain their individuality even in the face of strong pressures to give in. In general, he viewed conformity as a sign of a weak, authoritarian personality, prone to unreflective obedience. — John F. Dovidio, Peter Glick, Laurie A. Rudman, On the Nature of Prejudice, 1891
