Conformity and Cultural Influence on Behaviour

Welcome to this lesson on how people are shaped by the groups and cultures around them, students 👋 In everyday life, people often change what they say, how they act, or even what they believe because of social pressure, cultural expectations, or a desire to fit in. In IB Psychology HL, this is part of the Sociocultural Approach to Understanding Behaviour, which explains behaviour by looking at the social world around the person, not just the individual mind.

Lesson Objectives

By the end of this lesson, you should be able to:

• Explain key ideas and terms related to conformity and cultural influence.
• Describe how people are influenced by norms, groups, and culture.
• Apply psychological research to real-life examples of social influence.
• Connect conformity and culture to identity, stereotyping, enculturation, acculturation, and globalisation.
• Use evidence from studies to support psychological explanations.

Why do people change their behaviour?

Imagine students is in a classroom where everyone is quiet during a discussion. Even if students has a different opinion, speaking up might feel risky because it could lead to embarrassment or rejection 😬 This is one simple example of conformity, which is when a person changes behaviour, attitudes, or beliefs to match a group.

Conformity is important in psychology because it shows that behaviour is not always based only on personality or individual choice. Often, people adjust what they do because they are influenced by social norms, group pressure, and cultural expectations. A norm is an accepted way of behaving in a group or society. Norms can be explicit, like rules in a school, or implicit, like understanding that people should wait their turn in a line.

The sociocultural approach argues that behaviour is strongly shaped by the social context. This means that what seems “normal” in one culture may seem unusual in another. For example, making direct eye contact may be seen as confident in some places, but disrespectful in others. This shows that behaviour cannot always be understood without considering culture 🌍

Key types of conformity

Psychologists often describe conformity in different ways.

Compliance happens when a person agrees with the group publicly but does not necessarily agree privately. For example, students may laugh at a joke in a group even if it is not actually funny, just to avoid standing out.

Identification happens when a person changes behaviour because they want to be like someone or some group they admire. For example, a student might copy the style or speech of a popular group to feel included.

Internalization is when a person accepts the group’s beliefs both publicly and privately. This is the deepest form of conformity because the person truly changes their attitude.

Psychologists also distinguish between two major social influences:

• Normative social influence: conforming to be liked or accepted.
• Informational social influence: conforming because you believe the group knows better, especially in uncertain situations.

For example, if a group of students all choose the same answer on a difficult question, students might copy them because the task feels confusing. That would be informational influence. If students copies them to avoid looking odd, that would be normative influence.

Classic research on conformity

One of the most famous studies is Asch’s line judgment experiment. In this study, participants were asked to compare the length of lines. Confederates in the group deliberately gave the same wrong answer. Many real participants also gave the wrong answer at least once, showing that group pressure can lead people to conform even when the correct answer is obvious.

Asch’s study is useful because it shows that conformity is not just about confusion. People sometimes know the right answer but still go along with the group. This supports the idea that social pressure can be very powerful.

Another important idea is that conformity tends to be stronger when:

• the group is unanimous,
• the group is larger, though only up to a point,
• the task or situation is unclear,
• the person feels low confidence or low social support.

For example, if everyone in a group project agrees to use one idea, students may feel pressure to agree too, especially if no one else speaks up. This kind of situation shows how social influence works in real life 🧠

Culture and behaviour

Culture is a shared system of values, beliefs, customs, and rules that guide behaviour in a group of people. Culture affects how people think about the self, relationships, authority, and social responsibility.

A key distinction in psychology is between individualist cultures and collectivist cultures.

• In individualist cultures, people are often encouraged to be independent, unique, and self-expressive.
• In collectivist cultures, people are often encouraged to value group harmony, family duties, and social roles.

This does not mean every person in a culture behaves the same way. However, cultural values can influence what kinds of behaviour are rewarded or discouraged.

For example, in an individualist setting, saying “I disagree” may be seen as confidence. In a collectivist setting, the same behaviour might be viewed as disruptive if it threatens group harmony. These differences show that conformity is not simply a sign of weakness; sometimes it is a culturally supported way to show respect.

Enculturation and acculturation

Two important terms in this topic are enculturation and acculturation.

Enculturation is the process of learning the values and norms of one’s own culture from family, school, media, and community. It starts early in life and helps people understand what behaviour is expected.

For example, a child may learn to say “please” and “thank you,” to respect elders, or to take turns in conversation. These behaviours are not automatic; they are learned through socialization and repeated practice.

Acculturation is the process of adapting to a new culture when someone moves to a different society or comes into long-term contact with another culture. A person may adopt some new customs while keeping parts of their original culture.

Acculturation can create stress if the old and new cultural expectations conflict. For example, a teenager who moves to a new country may feel pressure to dress or speak like peers in school while still following family traditions at home. This can affect identity, confidence, and behaviour.

Psychologists often explain that acculturation may involve different strategies, such as maintaining the original culture, adapting to the new culture, or balancing both. This shows how culture shapes behaviour across time and across life changes.

Globalisation and social influence

Globalisation refers to the increasing connection of countries through media, technology, trade, travel, and communication. It spreads ideas, fashion, music, and values across the world 🌐

Because of globalisation, young people may see similar trends on social media, even if they live in different countries. This can influence conformity in new ways. For example, a hairstyle, slang term, or online challenge may spread quickly because people want to fit into a global peer culture.

Globalisation can also affect cultural identity. Some people may feel their local traditions are becoming less important, while others may combine local and global influences. This can change how people conform, what they value, and how they define themselves.

A simple example is a student who follows both family traditions and online trends. students might follow a family rule about polite behaviour at home, but use different language with friends online. This shows that behaviour can shift depending on the social setting.

Applying the sociocultural approach in IB Psychology

To score well in IB Psychology HL, students should not just memorize definitions. students should also explain behaviour using the sociocultural approach.

Here is a strong way to think about an exam response:

1. Define the key term, such as conformity.
2. Explain the social or cultural reason behind the behaviour.
3. Use a study or example as evidence.
4. Link the explanation back to the broader sociocultural approach.

For example, if asked why people conform, students could explain that conformity may help people gain acceptance or reduce uncertainty. Then students could refer to Asch’s findings to show that group pressure can change responses even when the correct answer is obvious. Finally, students could connect this to culture by noting that social norms differ across societies, so conformity is shaped by both the immediate group and the larger cultural setting.

This approach shows critical thinking because it moves beyond simple description. It explains how behaviour is learned, influenced, and changed by the social environment.

Conclusion

Conformity and cultural influence are central to the sociocultural approach because they show that behaviour is shaped by the people and cultures around us. Conformity happens when individuals adjust their behaviour, beliefs, or attitudes because of group pressure or social norms. Culture adds another layer by shaping what people learn, value, and accept as normal. Through enculturation, people learn the rules of their own culture. Through acculturation, they adjust to new cultural settings. Globalisation then spreads new norms and influences across societies. Together, these ideas help psychologists understand why behaviour can differ across groups and change across situations.
