2 experiments were conducted to investigate postdecisional dissonance reduction processes following a commitment to bet on a horse in the natural and uncontrived setting of a race track. In the 1st study, 69 2 Win bettors rated the chance that the horse they had selected would win the forthcoming race and 72 other bettors provided ratings immediately after making a 2 Win bet. On the 7-point rating scale employed, prcbet subjects gave a median rating of 3.48, which corresponded to a fair chance of winning; postbet subjects gave a median rating of 4.81, which corresponded to a good chance of winning. This difference was significant beyond the .01 level. The general findings were replicated in a 2nd study in which harness-race patrons rated how confident they felt about their selected horse either just before or just after betting. Results from both studies provide support for Feslinger's theory in a real life setting and indicate that dissonance-reducing processes may occur very rapidly following commitment to a decision. In the last decade there have been numerous laboratory experiments conducted to test various implications of Festinger's (1957) theory of cognitive dissonance. In spite of sometimes serious methodological faults (cf. Chapanis & Chapanis, 1964), the laboratory evidence as a whole has tended to support Festinger's notions. Confidence in the theory, as Brehm and Cohen (1962) have previously suggested, can now be further strengthened by extending empirical tests from lifelike to real life situations. The present study investigates the effects of postdecision dissonance on bettors in their natural habitat, the race track. Festinger (1957) had originally contended that due to the lingering cognitions about the favorable characteristics of the rejected alternative(s), dissonance was an inevitable consequence of a decision. Subsequently, however, Festinger (1964) accepted the qualification that in order for dissonance to occur, the decision must also have the effect of committing the person. A favorite technique for reducing postdecisional dissonance, ac
