Americans' feelings about the performance of Congress range across the
spectrum from positive to negative, but tend to be negative. What acc
ounts for supportive or unsupportive orientations toward Congress; The
effects of personal attributes like socioeconomic status, or beliefs
about the efficacy of congressional processes, account for only part o
f citizens' evaluations of Congress. We argue that discrepancies betwe
en what people expect Congress to be like and what they perceive it ac
tually is like independently affect evaluations of Congress. We measur
e this ''expectation-perception discrepancy'' and demonstrate in a mul
tivariate explanatory environment that this discrepancy affects the ex
tent of Americans' favorableness toward Congress, drawing upon data ga
thered in a 1994 post-election survey (N = 808) conducted in Ohio by t
he Polimetrics Laboratory for Social and Political Research at Ohio St
ate University.
