Social influence in psychology explores how individuals and groups affect behavior and decision-making.
Conformity occurs when people change their behavior to match others' expectations or actions. Key explanations include Normative Social Influence, where people conform to be accepted and avoid rejection, and informational social influence, where individuals look to others for guidance in uncertain situations. Research shows conformity is affected by group size, unanimity, and cultural factors. Studies like Asch's line experiment demonstrate how powerful social pressure can be in driving conformity, even when individuals know the group is wrong.
Obedience involves following direct orders from authority figures. Legitimacy of authority plays a crucial role, as people are more likely to obey those they view as having genuine power and expertise. Situational factors greatly impact obedience levels, including proximity to authority, gradual commitment, and the presence of dissenting peers. Milgram's famous experiments revealed how ordinary people could be led to perform harmful acts through situational variables affecting obedience. The agentic state theory suggests people shift responsibility to authority figures when following orders. Minority influence represents how smaller groups can create social change through consistent messaging and behavior. Key factors in successful minority influence include consistency, commitment, and flexibility in approach. Notable examples include the civil rights movement and environmental activism, where dedicated minorities eventually shifted majority views. Research by Nemeth showed minorities can stimulate divergent thinking and creative solutions, even when their position isn't fully adopted. The effectiveness of minority influence often depends on the minority's style of behavior, with those who demonstrate unwavering commitment while remaining open to dialogue being most successful in creating lasting social change.
These social influence processes help explain both everyday conformity and major societal transformations. Understanding these mechanisms is crucial for analyzing how individuals navigate social pressures and how societies evolve through both majority and minority influences.
