The Power of Appearance: How Looks Shape Our Perceptions

It seems a lifetime ago when I used to take the old-slam door trains to London. The commute was gruesome, with huge delays par for the course. I don’t know what it’s like in other countries, but in Britain there are certain unspoken conventions one must follow when commuting.

Generally, you wait on the same part of the platform every morning. When getting on the train, you normally find a seat that you regularly sit in. If it’s already taken, then you find somewhere that roughly approximates to where you would normally settle down. Because most people follow this unspoken rule and because most people are creatures of habit, you invariably find yourself opposite a familiar face. Day in - day out, week in – week out, month in – month out. However these familiar faces almost always remain complete strangers. And obviously, as is the nature of human curiosity, you imagine what they must be like in every conceivable aspect of their lives. Much of our mental wanderings take us down paths that assumes what these fellow commuters are like personality-wise. Are they kind? Are they happy? Do they have children? And obviously, we judge them by how they look. I remember a commuter whose facial expression seemed to be permanently contorted with rage. His grimace gave him a malevolent countenance. You certainly wouldn’t trust him to look after your puppy for the weekend. Now, you could take the ‘don’t judge a book by its cover approach,’ but the thing is – we do. ?

The idea that a person’s physical appearance mirrors their character touches on a concept related to embodied cognition and social cognition in NLP and psychology. Embodied cognition suggests that cognitive processes are deeply rooted in the body's interactions with the world. This means that the way people speak, think, or even behave might be influenced by their physical appearance or bodily expressions, which include facial expressions, gestures, and posture. The idea that the way people look is the way they are, also relates to what we call, social cognition, where we make snap judgments based on appearances, leading to assumptions about personality traits.

This is because human beings are visual creatures, and we often make those snap judgments based on what we see. Whether it’s the clothes someone wears, their facial expressions, or how conventionally attractive they are, we tend to assign meaning to appearances—consciously or unconsciously. One of the most contentious aspects of this phenomenon is the role of beauty and how it influences our judgments, both positive and negative.

Do Beautiful People Have an Advantage?

Yes, in many ways, they do. Studies have consistently shown that attractive people tend to receive preferential treatment in various aspects of life. They are more likely to be hired, earn higher salaries, and even receive lighter sentences in court. This is referred to as the "halo effect," a cognitive bias where positive traits (like attractiveness) are assumed to be linked with other desirable qualities, such as intelligence or kindness.

One study published in the journal Psychological Science found that people tend to attribute positive personality traits, such as warmth and competence, to physically attractive individuals. It suggests that beauty isn’t just skin deep—it can affect how others perceive and treat you in profound ways.

The "Criminal Face" Bias: Does Appearance Predict Criminal Behaviour?

There’s also a darker side to how appearance influences judgment, particularly with regard to criminality. Some research has explored the idea of a "criminal face" and whether people who "look like" criminals are more likely to be involved in criminal behaviour.

A study conducted at Cornell University in 2011 found that people tend to associate certain facial features—such as asymmetry, a harsh jawline, or other distinct markers—with criminal behaviour. This bias was powerful enough that people who looked more "trustworthy" were less likely to be judged as guilty, even when they were.

However, this kind of thinking is flawed and dangerous. While some facial features might fit preconceived ideas of "trustworthiness" or "danger," there is no definitive link between someone's facial structure and their likelihood to commit a crime. The assumption that certain physical features are correlated with criminal behaviour is a stereotype, often fed by racial, gender, and cultural biases.

The Role of Stereotyping and Prejudice

The theory behind these perceptions often stems from evolutionary psychology, which argues that humans have developed a predisposition to judge based on appearance as a survival mechanism. In ancient times, quick judgments about someone’s physicality might have meant the difference between life and death. Today, however, these judgments can manifest as bias and prejudice, often leading to unfair treatment and discrimination.

How to Negate Prejudice Based on Appearance

For those who don’t conform to society’s narrow standards of beauty or "trustworthiness," these biases can feel particularly daunting. But there are ways to mitigate and push back against these prejudices:

1. Confidence is Key

One of the most effective ways to counteract appearance-based judgments is through self-confidence. How you carry yourself—your posture, eye contact, and manner of speaking—can have a profound impact on how others perceive you. Even if you don’t feel confident, projecting it can create a positive feedback loop.

2. Dress to Empower Yourself

Clothes may not make the person, but they certainly influence perception. Dressing in a way that makes you feel empowered can change how people see you. Choose outfits that reflect who you are and how you want to be perceived, whether it’s in a professional or social setting.

3. Develop Strong Communication Skills

Strong communication skills can help shift the focus away from appearance and toward the content of what you say. Being articulate, knowledgeable, and engaging can quickly override superficial judgments.

4. Own Your Uniqueness

Instead of hiding features that don’t conform to societal ideals, embrace them. Authenticity is attractive, and when people sense that you are comfortable in your own skin, they are less likely to focus on the superficial and more likely to appreciate you for who you are.

5. Build a Support Network

Having a solid support system can help buffer the negative effects of appearance-based judgment. Surround yourself with people who value you for your qualities beyond your looks. Their validation can provide confidence and emotional support when you face unfair treatment.

6. Challenge Prejudices Actively

Finally, don’t shy away from challenging others when they make appearance-based assumptions. Whether it’s calling out a colleague for stereotyping or simply living in a way that defies these biases, be proactive in changing how people think about beauty and worth.

While it's clear that attractive individuals often enjoy certain privileges, the assumption that people who look a certain way—be it beautiful or "criminal"—are inherently different is a harmful stereotype. In a world where looks can heavily influence perceptions, recognizing and actively working against appearance-based prejudices is essential for building a more inclusive society. By focusing on confidence, communication, and embracing individuality, anyone can overcome the challenges that arise from superficial judgments.
