The Science of Gaining Compliance provides readers with an examination of key compliance-gaining techniques with the goal of making sense of their form, effects, mediators, and moderators. Readers learn how compliance-gaining differs from other forms of social influence, such as persuasion, because it takes place in the active communication context of interpersonal encounters. The text emphasizes how compliance-gaining techniques don't rely on applying pressure and also focus on changing behavior, rendering them a unique form of interpersonal communication. Opening chapters introduce the concept of compliance-gaining and investigate multimessage techniques, including foot-in-the-door, door-in-the-face, and temptation techniques such as lowballing, bait-and-switch, and the lure. Later chapters present a set of single-message techniques, including pregiving, instilling guilt, direct requests, and confusion strategies. The final chapter summarizes each of the techniques as well as their similarities and differences.
