概要	The bogus pipeline, devised by Jones and Sigall in 1971, is a methodological technique for reducing social-desirability bias in the measurement of attitudes, especially sensitive ones such as prejudice. Participants are connected to an impressive-looking apparatus and convinced that it functions as an accurate lie detector capable of revealing their true feelings. Believing that dishonesty will be exposed, participants are motivated to report their attitudes truthfully rather than giving socially acceptable answers. In the classic procedure participants are asked to predict what the machine will say about them, which encourages them to consult and disclose their genuine attitudes. By comparing reports given under the bogus pipeline with ordinary self-reports, researchers can estimate the extent of social-desirability distortion and obtain more candid measures of socially sensitive attitudes. The technique was an early and influential solution to a fundamental problem in attitude measurement.	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.
