Welcome to Unit 1: Social Psychology!

Have you ever found yourself laughing at a joke you didn't understand, just because everyone else was? Or maybe you’ve changed your clothes because they weren't "in style" anymore? If so, you’ve experienced conformity. In this chapter, we explore why humans have such a strong urge to "fit in" and how famous psychologists like Solomon Asch proved just how far we will go to follow the crowd.

Don't worry if some of the terms seem similar at first. We will break them down into simple pieces to help you ace your Unit 1 exam!

1. What is Conformity?

Conformity is a type of social influence where an individual changes their belief or behaviour in order to fit in with a group. This change is often a response to real or imagined group pressure.

Three Types of Conformity

Psychologists suggest that not all conformity is the same. Some are shallow, while others are deep and permanent:

  • Compliance: This is the shallowest level. You go along with the group in public to avoid conflict, but privately, you don't change your mind. Example: Cheering for a sports team because your friends are, even though you don't actually like them.
  • Identification: This is a middle level. You conform to the group because there is something about them you value or identify with. You want to be a part of that group, so you adopt their behaviour. Example: Dressing like a specific "clique" at school because you want to be seen as one of them.
  • Internalisation: This is the deepest level. You go along with the group because you genuinely believe they are right. This leads to a permanent change in behaviour, both publicly and privately. Example: Living with vegetarians at university and genuinely deciding that eating meat is wrong, even after you move out.

2. Explanations: Why Do We Conform?

Psychologists Deutsch and Gerard suggested two main reasons why people conform. Think of these as the "Need to be Liked" and the "Need to be Right."

Normative Social Influence (NSI) — The Need to be Liked

This happens when we conform to be accepted by the group and to avoid rejection or "standing out like a sore thumb." NSI usually leads to compliance. It happens most often when we are with people we know and care about, or in stressful situations where we need social support.

Informational Social Influence (ISI) — The Need to be Right

This happens when we are unsure of what to do or what the "right" answer is. We look to the group for information because we assume they know more than we do. ISI usually leads to internalisation. It happens most often in new or ambiguous (unclear) situations.

Quick Tip: If you're struggling to remember these, just think: Normative = Normal (fitting in), and Informational = Information (seeking the truth).

3. The Classic Study: Asch (1951)

Solomon Asch wanted to see if people would conform to a group even when the group was obviously wrong.

The Procedure

  • Asch used \(123\) male American undergraduates.
  • Each participant was placed in a group with \(6\) to \(8\) confederates (people who were in on the experiment).
  • The group was shown two cards: one with a "standard line" and one with three "comparison lines" (A, B, and C).
  • Their task was to say out loud which comparison line was the same length as the standard line. The answer was always obvious.
  • The real participant always gave their answer last or second-to-last.
  • In \(12\) "critical trials" out of \(18\), the confederates all gave the same wrong answer.

The Findings

The results were surprising. Even though the answer was clearly visible:

  • The real participants gave the wrong answer \(36.8\%\) of the time.
  • \(75\%\) of the participants conformed at least once.
  • \(25\%\) of the participants never conformed at all.

Conclusion

Asch concluded that people will conform to a majority even when the majority is clearly wrong. When interviewed afterward, most participants said they conformed to avoid rejection (Normative Social Influence).

4. Asch's Variations (1952, 1956)

Asch didn't stop there. He changed his experiment to see what factors made conformity stronger or weaker.

  • Group Size: Asch found that with only \(1\) or \(2\) confederates, conformity was very low. However, when the group size rose to \(3\) confederates, conformity jumped to about \(31.8\%\). Adding more people after \(3\) didn't make much difference.
  • Unanimity: Asch introduced a "dissenter" (a confederate who gave the right answer or a different wrong answer). Having just one person disagree with the majority caused conformity to drop significantly. This shows that the influence of the majority depends on the group being unanimous.
  • Task Difficulty: Asch made the lines more similar in length (making the task harder). He found that conformity increased. This is because the situation became ambiguous, so participants looked to others for the right answer (Informational Social Influence).

5. Factors Affecting Conformity

Why do some people conform more than others? We can categorise these factors into three areas:

Individual Differences (Personality)

Some people have a higher "need for affiliation" (a need to be in a relationship with others). These people are more likely to conform. Also, people with low self-esteem or a high need for social approval are more likely to follow the crowd to feel secure.

Situational Factors

These are things about the environment, such as group size and task difficulty (as seen in Asch's variations). If the group is large and the task is hard, you are much more likely to conform.

Culture

Psychologists have found that culture plays a huge role:

  • Individualist Cultures: (e.g., the UK, USA) People are encouraged to be independent and focus on their own goals. Conformity rates tend to be lower.
  • Collectivist Cultures: (e.g., China, Korea) People are encouraged to put the needs of the group first. Conformity rates tend to be higher because it is seen as a way of keeping the peace and showing loyalty.

Key Takeaways for Your Revision

Types: Compliance (public change), Identification (group membership), Internalisation (private change).

Explanations: NSI (to be liked) and ISI (to be right).

Asch (1951): Proved people conform to a wrong majority. Conformity rate was \(36.8\%\).

Variations: Group size (peaked at \(3\)), Unanimity (dissenter drops conformity), Task Difficulty (harder task = more conformity).

Factors: Personality (need for approval), Situation (difficulty/size), and Culture (Individualist vs. Collectivist).
