সারসংক্ষেপ	The lost letter technique, introduced by Milgram, Mann, and Harter in 1965, is an unobtrusive field method for measuring community attitudes by exploiting a small act of everyday helping. Researchers distribute stamped, addressed envelopes in public places as if they had been accidentally dropped, with the letters addressed to different organizations representing varying causes (for example, a neutral individual versus a politically charged group). A passerby who finds a letter must decide whether to mail it, ignore it, or destroy it, and the proportion of letters returned for each addressee serves as an index of public sentiment toward that cause -- letters addressed to favored organizations are mailed more often than those to disfavored ones. Because finders do not know they are participating in a study, the measure sidesteps social-desirability bias and yields a behavioral, aggregate indicator of attitudes that complements self-report surveys.	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.
