One Argument That Is an Alternative to the Dissonance Reduction

One argument that is an alternative to the dissonance reduction explanation given by Dickerson et al. is that subjects in the "hypocrisy" condition:

A) were more likely to hold liberal political beliefs and thus be more friendly to ideas such as recycling and water conservation.
B) were "primed" to think more about water conservation, thus enhancing those attitudes.
C) actually felt less dissonance in the "hypocrisy" condition and therefore were less likely to conserve water.
D) felt a temporary decline in their self-esteem and were therefore more compliant to the experimenter's requests.
