Conformity answers a group; obedience answers an authority.
Conformity and obedience are not synonyms. Conformity responds to a group's unspoken standard; obedience responds to an authority's direct instruction. Naming the wrong one changes which research the answer is about.

Culture and helping
- Individualism 个人主义, collectivism 集体主义 and multiculturalism 多元文化主义 shape how a person perceives and behaves in groups.
- Altruism 利他行为 is selfless behaviour, though some researchers argue prosocial acts carry internal rewards.
- The bystander effect 旁观者效应 shows that situational and attentional variables predict whether someone helps — superordinate goals 超级目标 unite separate groups.
A person collapses on a busy street and no one helps; on an empty street a single passer-by helps immediately. The bystander effect predicts exactly this: more witnesses spread responsibility and make each person less likely to act.
Social norms and roles set expectations; influence is normative or informational. Conformity answers a group, obedience an authority. Group polarisation, social facilitation and the false consensus effect are group effects, and the bystander effect shows helping depends on the situation.
