Harold Kelley Quote

A person is known by the behavior he displays consistently. An experiment by Himmelfarb (1972) makes the important point that consistency in other persons' characterizations of an actor carries more weight if they are based on observations in dissimilar rather than similar situations. The other side of the coin is that a person's inconsistent behavior is attributed not to him but to circumstances.
