Sintesi	The false consensus paradigm, established by Ross, Greene, and House in 1977, demonstrates a pervasive bias in social perception: people overestimate the extent to which others share their own choices, beliefs, and behaviors. In the canonical procedure, participants indicate their own position on some issue or choice -- famously, whether they would walk around campus wearing a sandwich-board sign -- and then estimate what proportion of their peers would do the same. The signature finding is that those who choose a given option estimate that option to be more common than do those who reject it, so each group projects its own response onto others. Ross and colleagues also showed that people view their own responses as relatively common and unrevealing of personality while seeing differing responses as uncommon and diagnostic of others' traits. The paradigm became a foundational demonstration of egocentric bias in social judgment and attribution.	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.
