Stereotype psychology: Why do we stereotype others?

Stereotyping means attributing a personality trait or a set of personality traits to a group of people. These traits may either be positive or negative and stereotyping of groups is usually done on the basis of age, gender, race, region, religion, etc.

For example, “Men are aggressive” is a stereotype based on gender while “Italians are friendly” is a stereotype based on region.

At its core, a stereotype is a learned/acquired belief about a group of people. We acquire stereotypes from the culture we live in and the information we’re exposed to. Not only are stereotypes learned unconsciously but stereotyping happens unconsciously too.1

This means that even if you may consider yourself free from any stereotypes, you’ll still stereotype people unconsciously. It’s an inescapable feature of human nature.

To test the degree of unconscious stereotyping in people, scientists use what’s known as 'Implicit Association Test'. The test involves showing subjects images quickly and gauging their response to figure what associations they hold in their minds before they get the time to think and react in more conscious and politically correct ways.

It’s these association tests that have revealed that even people who consciously think they don’t stereotype are prone to unconscious stereotyping.

Origins of stereotyping

Why is stereotyping such a pervasive feature of human psychology?

To answer this question, we go back to the Palaeolithic environments in which most of our psychological mechanisms evolved. Humans at the time organized themselves in nomadic groups with around 150-200 members in each group. They didn’t have to keep track of a large number of people. They only had to remember the names and personality traits of around 150-200 people.

Today, the societies in which people live have exponentially large populations compared to ancient times. One would expect that humans should now be able to remember the names and traits of much more people.

But this hasn’t happened. People don’t remember more names simply because they live in larger societies. The number of people a person remembers by name still correlates with what was expected of him during the Palaeolithic times.2

So how do you go about identifying and understanding the immensely large number of people that live in the world today?

You identify and understand them by categorizing them. Anyone who has studied Statistics knows that inordinate amounts of data can be better dealt with by organizing and categorizing it.

Stereotyping is nothing but categorizing. You treat groups of people as individuals. You categorize and attribute traits to groups of people based on their country, race, region, sex, etc.

Stereotyping = Cognitive efficiency

Stereotyping is, therefore, a way to efficiently understand a large number of people by dividing them into groups.

The “Women are emotional” stereotype gives you knowledge about half of the human population so you don’t have to survey or study every single woman on the planet. Similarly, “Blacks are hostile” is a stereotype that lets you know that there’s a group of people with a non-friendly predisposition.

As you can see, stereotyping is generalizing and it can blind you to the fact that a significant number of people within the stereotyped group may not fit the stereotype. In other words, you don’t consider the possibility that “All women are not emotional” or “Every black person is not hostile.”

But stereotypes are there for a reason

Stereotypes usually have a kernel of truth in them. If they didn’t they wouldn’t get formed in the first place. For instance, the reason why we don’t come across stereotypes such as “Men are emotional” because men, on average and unlike women, are good at hiding their emotions.

The point is that stereotypes are not born out of thin air. They have good reasons to exist. At the same time, not all individuals in the stereotyped group will necessarily possess the traits associated with the group.

So when you stereotype someone, the odds that you're right and wrong are both there. Both possibilities exist. 

Us vs Them

Perhaps the most important function of stereotyping is that it helps us differentiate between friend and foe. Typically, people within one’s social group are likely to be perceived favorably while outgroups are likely to be perceived unfavorably.

This not only helps us feel good about ourselves and our group identity but also enables us to denigrate and sometimes even dehumanize outgroups. Negative stereotyping of outgroups has been a feature of human conflict throughout history.

Also, negative stereotyping is more powerful than positive stereotyping. Neuroscience studies show that our brains respond more strongly to information about groups portrayed unfavorably.3 

To our hunter-gatherer ancestors, not being able to differentiate friend from foe could’ve easily meant death. 

How stereotypes get broken

Stereotyping is learning by association. It works in the same way as do all other beliefs. If you’re exposed to only one type of associations, you’ll solidify them over time. If you’re exposed to contradictory associations, there’s a chance you’ll break the stereotype.

For instance, if you previously believed that “Africans are ignorant people” then watching Africans succeed on intellectual fronts could serve to break your stereotype.

However, not all of us have an equal ability to break free from stereotypes. A recent study published in the Journal of Experimental Psychology showed that people with higher cognitive abilities (such as pattern detection) are more likely to learn as well as break free from stereotypes on exposure to new information.4

In other words, smartness is required to learn and unlearn stereotypes, just as it is required to learn and unlearn all else.

Body language: Gestures of the head and neck

The head nod
Nodding the head almost everywhere in the world means ‘Yes’ and shaking the head from side to side means ‘No’. A slight head nod is used as a greeting gesture, especially when two people greet each other from a distance. It sends the message, ‘Yes, I acknowledge you’.

Body language: The truth of the pointing foot

When we communicate with others, our attention is focused mainly on the words they speak and the facial expressions they make. We pay little, if any, attention to gestures of the body and when it comes to the feet, we almost never look at them.

Body language: Clenching and clasping of the hands

Clenching hands in front of the body
This gesture has three main positions: hands clenched in front of the face, hands clenched resting on the desk or lap and, while standing, hands clenched over the lower abdomen.

Body language: Crossing the arms

Crossing the arms across the chest is a classic gesture of defensiveness. This defensiveness usually manifests as uneasiness, shynessor insecurity.

What makes a person stubborn

Stubbornness is a personality trait in which a person refuses to change his opinion about a situation or refuses to change his mind about the action that he has decided to take.

Body language: Hands touching the head

Scratching the hair
When we scratch our hair using one or more fingers anywhere on top, back or side of the head, it signals the emotional state of confusion. Watch any student trying to solve a difficult problem and you are likely to observe this gesture. There isn't a better place to observe this gesture than an exam hall, where students often have no idea what the question paper is trying to say!

How our past experiences shape our behavior and personality

Our beliefs and needs are the strongest factors that govern our behavior. Ultimately, it all comes down to beliefs because a need is also a belief- a belief that we lack something.
