FESTINGERS THEORY OF COGNITIVE DISSONANCE
FESTINGERS THEORY OF COGNITIVE DISSONANCE The most general of all the consistency theories and, as one might expect, the one that has generated the largest body of empirical data is Leon Festinger's theory of cognitive dissonance. It is also a theory that has generated considerable controversy in the field of social psychology.
