Cognitive Dissonance Summary
Jost et al (unpublished) offer the following fascinating review of cognitive dissonance:
Cognitive dissonance theory is one of the very few psychological theories that genuinely aims to integrate social, cognitive, emotional, motivational, and behavioral aspects of human functioning (Festinger, 1957). The core assumption of dissonance theory is that people are motivated to resolve inconsistencies among their thoughts, feelings, and behaviors and thus to provide justifications or rationalizations for their experiences. Cognitive dissonance theory is a much-cherished theory in social psychology for a good many reasons (see Harmon-Jones & Mills, 1999 for a recent tribute), but chief among these is that it often contradicts the seemingly unassailable assumptions of reinforcement theory, self-interest, rational choice economics, and common sense. In social psychology, perhaps more than in other scientific endeavors, the ability to predict and account for paradoxical effects is a reliable predictor of active research interest and theoretical longevity. Because of the counter-intuitive nature of cognitive dissonance theory, it has also proved more useful than most psychological theories to economists, sociologists, and political scientists seeking to understand behavioral anomalies in each of these fields (e.g., Akerlof & Dickens, 1982; Baron & Kreps, 1999; Liebow, 1967; Montgomery, 1994; Rabin, 1994).
Empirical highlights of cognitive dissonance theory include counter-intuitive demonstrations that people are more likely to rationalize their own hypocrisy when they are paid poorly rather than handsomely for their transgression (Festinger & Carlsmith, 1959), work harder and praise a job that pays nothing rather than a job that pays something (Weick, 1964), increase rather than decrease commitment to a group or organization following abuse and maltreatment (Aronson & Mills, 1959; Gerard & Mathewson, 1966), stick longer with a failing course of action than a successful one (Staw, 1976), and profess greater than usual liking for the taste of grasshoppers following compliance with hostile orders to eat them (Zimbardo, Weisenberg, Firestone, & Levy, 1965)… A paradoxical consequence of suffering, according to cognitive dissonance theory, is that people can become more committed to their own state of suffering rather than taking clear and unambiguous action to terminate their pain.
