Sammanfattning	The Asch conformity paradigm, established by Solomon Asch in the 1950s, demonstrates the power of group pressure to make people publicly endorse a manifestly false judgment. A naive participant joins a group of confederates for a simple perceptual task -- matching the length of a standard line to one of three comparison lines, where the correct answer is obvious. On certain critical trials the confederates unanimously give the same wrong answer, and the experimenter measures how often the lone real participant goes along with the majority against the evidence of their own eyes. Asch found that a substantial proportion of participants conformed at least once, even on an unambiguous task, while systematic variations revealed that conformity rises with majority size up to a point and collapses when unanimity is broken. The paradigm became the canonical demonstration of normative social influence.	Cover story and deception design is the methodological practice of concealing a study's true purpose behind a plausible false rationale so that participants behave spontaneously rather than in line with what they think the experimenter wants. Because people who guess a study's hypothesis may consciously or unconsciously alter their behavior -- the problem of demand characteristics -- social psychologists often present a cover story that misdirects attention, embed the real dependent measure within an apparently unrelated task, and, when necessary, use additional deceptions such as confederates or false feedback. This approach made possible many of the field's classic findings on conformity, obedience, helping, and dissonance, where awareness of the true question would have destroyed the phenomenon. Deception carries serious ethical obligations, requiring justification, minimization of harm, suspicion probing, and thorough debriefing, which contemporary practice and ethics codes strictly govern.	The Milgram obedience paradigm, devised by Stanley Milgram in the early 1960s, measures the extent to which ordinary people will obey an authority figure's commands to harm another person. A naive participant is assigned the role of teacher and instructed by an experimenter to administer increasingly severe electric shocks to a learner (a confederate) for errors on a memory task, with a switchboard labeled up to 450 volts and ominous warnings. No real shocks are delivered, but the participant believes they are, and the learner's scripted protests escalate to screams, then silence. When participants hesitate, the experimenter issues standardized prods to continue. Milgram found that a majority of participants obeyed to the maximum voltage despite visible distress, a result that overturned assumptions about individual conscience and became one of the most influential and controversial demonstrations in the history of psychology.
