Some prior considerations about dissonance to understand its reduction: Comment on McGrath (2017)

In a recent contribution to this journal, McGrath (2017) provided an overview of the reduction process of cognitive dissonance theory. To discuss the reduction strategy, she reviewed relevant studies and highlighted the means to reduce dissonance as well as factors that promote their use. In the present paper, we would like to raise some points which have not been considered by McGrath. First, we stress the historical development of the theory that orientated the study of attitude change as the major means of reduction. Second, we raise the issue of the term “dissonance” and the different conceptions about its reduction. Last, on the strength of published data, we insist on resistance to change as a central and essential factor to predict the reduction strategy. We consider that these elements, in addition to McGrath's valuable contribution, provide a comprehensive understanding of the current view of the dissonance reduction process.
