Social influence — Edexcel GCSE Psychology

Social influence explores how individuals' thoughts and actions are altered by others. Obedience involves following direct orders from a perceived authority figure, such as a student obeying a headteacher. Conformity is yielding to real or imagined group pressure, changing behaviour to fit in with a majority, like adopting a fashion trend. Deindividuation occurs when individuals lose their sense of personal identity and responsibility within a crowd, often leading to uncharacteristic or anti-social behaviour, such as rioting. The bystander effect is the phenomenon where a person is less likely to provide help in an emergency when other people are present, assuming someone else will intervene, such as ignoring a collapsed pedestrian on a busy street.

Bystander intervention is influenced by both personal and situational factors. Personal factors relate to the individual's characteristics, such as their level of competence; a person trained in first aid is more likely to help a collapsed individual. Other personal factors include the bystander's mood or their perceived similarity to the victim. Situational factors relate to the environment and context of the emergency. A key situational factor is the diffusion of responsibility, where the presence of multiple people reduces the psychological burden on any single individual to act. Additionally, the ambiguity of the situation and the potential cost of helping, such as physical danger or time lost, can deter intervention.

Conformity to majority influence occurs when an individual yields to group pressure, changing their behaviour to align with the majority. This is driven by the desire to fit in or the belief that the group is correct. Factors affecting conformity include personality and the situation. Personality factors, such as locus of control, play a role; individuals with an internal locus of control are less likely to conform because they rely on their own judgement. Situational factors include group size, task difficulty, and unanimity. For example, if a student is in a group where everyone else agrees on a wrong answer, they are more likely to conform if the group is unanimous, but less likely to conform if one other person dissents.

Obedience to authority involves following direct commands, typically from someone perceived as having legitimate power or higher status. Factors affecting obedience include both personality and the situation. Personality factors include the authoritarian personality, where individuals are highly submissive to authority and dismissive of subordinates, making them more likely to obey. Situational factors involve the environment or context, such as proximity to the authority figure, the presence of uniform, and the location. For example, a person is more likely to obey a police officer in uniform giving instructions at a busy intersection than a civilian giving the same instructions, due to the situational cues of legitimate authority.

Collective behaviour occurs when individuals act as part of a crowd, often behaving differently than they would alone. This shift is frequently driven by deindividuation, where anonymity reduces personal responsibility. The effect of collective behaviour manifests in two contrasting ways. Anti-social behaviour involves actions that harm others or disrupt society, such as rioting or vandalism. Conversely, crowds can also exhibit pro-social behaviour, which benefits others and society. Examples include peaceful demonstrations or bystanders collectively lifting a vehicle to save a trapped person. Understanding these dynamics explains why individuals in crowds conform to the group's prevailing mood, whether constructive or destructive.

Blind obedience occurs when individuals follow orders from an authority figure without questioning the moral implications. Preventing this requires strategies that empower individuals to resist unjust commands. One method is increasing personal responsibility, ensuring individuals know they will be held accountable for their actions, rather than shifting blame to the authority. Providing social support or role models of disobedience also helps; when one person defies an unjust order, others are more likely to follow suit. Education about the dangers of blind obedience raises awareness. Finally, encouraging individuals to question the motives and legitimacy of the authority figure allows them to critically evaluate commands before acting.
