概要	The confederate paradigm is a foundational methodological design in social psychology in which trained accomplices -- people who appear to be ordinary participants or bystanders but are actually part of the research team -- enact scripted behavior to create controlled social situations. By standardizing what confederates do, researchers can manipulate the social environment with precision while keeping the naive participant convinced the situation is real. Confederates have been the linchpin of many landmark studies: the unanimous wrong majority in Asch's conformity work, the passive bystanders in Latane and Darley's helping experiments, the learner in Milgram's obedience studies, and partners in countless interaction studies. The paradigm allows experimental control over otherwise uncontrollable social stimuli, making it possible to draw causal conclusions about how others' behavior shapes our own.	The induced (forced) compliance paradigm, introduced by Festinger and Carlsmith in 1959, is the classic experimental test of cognitive dissonance theory. Participants are led to perform a counter-attitudinal act -- typically telling another person that a boring task was enjoyable -- under either low or high justification (in the original, paid one dollar versus twenty dollars). Dissonance theory predicts the counterintuitive result that those paid less change their private attitudes more, coming to actually believe the task was enjoyable, because a small incentive provides insufficient external justification for the lie, leaving them to reduce the resulting discomfort by aligning their attitude with their behavior. Festinger and Carlsmith found exactly this inverse relationship between incentive and attitude change, providing striking support for dissonance theory and overturning reinforcement-based predictions that larger rewards produce more attitude change.
