© 2013 WUPJ, September 2013, Volume 1 Social Reducing Cognitive Dissonance Through Effort Justification: Evidence From Past Studies and Daily Experience Kristin H. G. Maich* The present paper defines and examines past research in the area of cognitive dissonance and provides evidence for the occurrence of effort justification in animals, including humans. The ways in which cognitive dissonance and effort justification occur in everyday life are then discussed. People generally consider the behaviour to determine their attitude towards experience of tension to be both undesirable and that goal. If much effort has been spent in the unsustainable, thus people seek to reduce attainment of a goal, it should come to be seen tension when it occurs. The phenomenon of as worthwhile and therefore more attractive. A cognitive dissonance occurs when an individual reward’s perceived value is augmented in order simultaneously holds two inconsistent to justify any arduousness involved in its cognitions as true (Festinger, 1957). acquisition (Zentall, 2010). This process Dissonance between cognitions manifests as minimizes cognitive dissonance. tension-inducing psychological discomfort, The present paper will examine past which motivates an individual to reduce research in the area of cognitive dissonance and dissonance in order to establish psychological provide evidence for the occurrence of effort consistency. In general, people attempt to avoid justification in animals, including humans. This situations that may result in cognitive paper will then demonstrate how cognitive dissonance. According to Festinger, when dissonance and effort justification may occur in dissonance does occur, people attempt to reduce everyday life. it in one of three ways: change one of the dissonant cognitions; add new cognitions that Evidence for the Effort Justification Effect are consonant with what one already believes; or Justifying the Effort of Weight Loss Therapy decrease the perceived importance of the Seeking to expand upon prior research, dissonant cognition.

As predicted, Festinger and the effect of choice on effort justification, but all Carlsmith found that opinion change (i.e., participants reported a high level of freedom to enjoyability of the task from bad to good) was participate. Thus, the choice manipulation did the largest in participants who were given a not have an effect on reported freedom of smaller reward (one dollar) than in those given a choice. However, the effort justification larger reward (20 dollars). Because there was paradigm holds that freedom of choice should less external reason (i.e., less money) for be high in order for cognitive dissonance to take participants to champion the study in the one- place, and since this is precisely the sentiment dollar condition, the researchers proposed that expressed by the majority of the participants, the level of cognitive dissonance was highest Axsom and Cooper deemed the findings valid. when participants did act to endorse the study in As hypothesized, after three weeks, weight loss this condition. Therefore, these participants was significantly greater in the high effort group were more motivated than the participants in the compared to the other groups.

To reduce the dissonance, maintained, and indeed, was even greater, by the researchers asserted, participants justified participants in the high effort condition after 6 their effort by changing their own attitude and 12 months.
