Social Judgment Theory is a way to explain when persuasive messages are most likely to succeed and how people make judgments about them. This theory is often covered in communication theory and persuasion courses, but is also applicable when discussing persuasion in basic speech and introductory communication courses. Social Judgment Theory attempts to explain how likely a person might be to change their opinion, the probable direction of that change, their tolerance toward the opinion of others, and their level of commitment to their position. Social Judgment Theory also illustrates how people compare their personal positions on issues to other people's positions. This article presents an activity that requires students to take a stand on a variety of issues and thereby engages them actively to understand how Social Judgment Theory functions to persuade in their everyday lives.
