IB DP Psychology — Sociocultural Approach | SL & HL | Paper 1
🎯 Learning Intentions By the end of this note, you will be able to:
- Define conformity, compliance, informational social influence, and normative social influence using IB-aligned terminology.
- Explain the difference between conformity and compliance, and the conditions under which each is more likely to occur.
- Describe the role of group size, unanimity, and social norms in shaping conformist behaviour.
- Evaluate research evidence for conformity and compliance using supporting and opposing studies in ACAS format.
- Apply conformity and compliance concepts to a real-world case study from the sociocultural perspective.
- Discuss the extent to which social pressure provides a complete explanation of group behaviour.
- Analyse conformity and compliance research using relevant concept areas: Bias, Causality, Perspective, and Responsibility.
Introduction & Context
Imagine you are sitting in a waiting room with five other people. A fire alarm begins to sound, but nobody around you moves. They glance at each other, look mildly inconvenienced, and return to their phones. What do you do? Most people, despite their better instincts, stay seated. They look to others for cues about how to behave, and when those cues suggest that nothing is wrong, they override their own judgment. This is not weakness or stupidity — it is a deeply human response to social uncertainty.
This kind of behaviour — adjusting what we do or think in response to the real or imagined presence of others — is at the heart of social psychology. Humans are fundamentally social animals. We evolved in groups, and group membership has historically been essential for survival. It is no surprise, then, that we are exquisitely sensitive to social signals. The question psychologists ask is: under what conditions do people conform, why do they do it, and what does this tell us about the relationship between the individual and the group?
🔁 Analogy — The Crowd at a Concert Think about the moment at a concert when everyone around you starts clapping in a slow, rhythmic beat. Even if you had no intention of clapping, you almost certainly join in. You are not forced to. Nobody threatens you. But the social pull is almost irresistible. This is conformity in its most visible form — your behaviour changes not because of a direct request, but because the group's behaviour creates an implicit standard that feels natural to follow.
Core Concepts
When we talk about how groups shape individual behaviour, we need to distinguish between two related but meaningfully different phenomena. The first is a broad, often unconscious shift in a person's attitudes or behaviours to match those of a group. The second is a more specific response to a direct or indirect request. Understanding this distinction is essential for both conceptual clarity and exam performance.
📖 Key Definition — Conformity Conformity is a change in a person's behaviour, attitudes, or beliefs as a result of real or imagined group pressure. It occurs without a direct request — the individual adjusts to align with perceived group norms or expectations.
Conformity is not simply about doing what others do. It involves an internal shift — or at least the appearance of one — in response to social pressure. The key word in the definition is "imagined": we do not need to be physically surrounded by a group for conformity to occur. A
