Cognitive Dissonance

Cognitive Dissonance and Public Commitment
By Kurt Mortensen

Public commitments and dissonance go hand in hand. Even when we feel an action is not right, we still go through with it if we have publicly committed to such a course of action.

The more public our stand, the more reluctant we are to change it. A now famous experiment conducted in 1955 by Morton Deutsch and Harold Gerard demonstrates this principle. A group of students were divided into three groups. Each group viewed some lines and had to estimate their length. The students in the first group had to privately write down estimates, sign their names to it, and hand it in. The second group of students also had to privately write down their estimates on a Magic Writing Pad. They could lift the plastic cover on their notepad and their figures would instantaneously disappear. The third group of students did not write down their estimates but just kept them privately in their minds. Not surprisingly, even when new information was presented contradicting their estimates, the students who had written down their estimates, signed their names to them, and handed them in remained the most committed to their choices, while those who had never committed anything to writing were the most readily swayed to change their responses

Procedures, customs, and traditions are often specifically established for the purposes of creating psychological commitment. Consider fraternity initiations, military boot camps, political rallies, protest marches, and demonstrations. When we make our vows, beliefs, statements, or endeavors public, we feel bound to them. We can back out on commitments and claims we've made public, but we will pay a psychological and emotional price. What's more, the more public we made those commitments, the greater the emotional price tag will be.
