Document Summary
Perception and misperception in international politics. (princeton, nj: Two elements will be dissonance if, the counterpart of one element would follow from the other, according to robert jervis; or simply, if two non-compatible elements are working together. Yet, this theory can be limited as pre- or post- decision period is ambiguous to identify, whether information are coherence or dissonance. Unlike merely wishful thinking, cognitive dissonance theory suggests that a person alters evaluation of alternative options, and he/or she only does it to favor made- decision, which may not necessarily be his or her preferred decision. Attempts to reduce dissonance would impact his or her future decisions, as he or she would prefer to remain as consistent as possible, and it is costly to regret a made decision. The magnitude of dissonance can vary depending on similarity and allure of the alternative option, as well as the importance of the decision.
