The hedonic relevance of an attitude object (or vested interest) is hy
pothesized as a major element fostering attitude-behavior consistency.
Hypothetically, various factors may attenuate effects of vested inter
est on attitude-behavior consistency, including attitudinal salience,
the certainty of the attitude-outcome link, the immediacy of attitude-
implicated consequences, and the self-efficacy of the individual to pe
rform an attitudinally implicated act. Effects of these factors were i
nvestigated in a large scale (N > 900 participants) simulation experim
ent. Results disclosed the overwhelming importance of stake, as hypoth
esized. In addition, the other factors had a powerful effect on attitu
de and subsequent attitude-behavior consistency. Implications of veste
d interest for developing a better understanding of the manner in whic
h attitudes ''behave,'' and affect behavior, were discussed.
