A few years back, I made changes to the biography of an account that I use fairly often. One of the things I included was that "I am into mindfulness and long hikes". At that time, I had only gone for two long hikes in that year, and meditated perhaps three times. Yet, it seemed good.

This is where the interesting thing comes in: Within a few months' time, I had already been doing both activities regularly. My morning meditation routine had taken off, and my long hikes had become a norm in my life. The script I created as an exaggeration was one I started to live up to.

Over the past few years, I have observed the same thing happen in others who create their own online profiles. Not only does a biography say who you are, but it begins to dictate who you will eventually be.

1. You perform a version of yourself — and then grow into it

As soon as you go about creating your profile, whether for social networking, meeting someone new, or joining a particular community, you start making decisions. What will you include? What will you exclude? Which of your features can be somewhat exaggerated?

The point is that once this curated image is created, it becomes something that will serve as the standard. You will take it into consideration and behave in accordance with what you have claimed to be.

In psychology, this phenomenon is called the "say-do" effect. Once people have publicly made themselves a commitment to act in a certain way, they become much more likely to fulfill it. And the image that you represent on your profile becomes the one you should stick to.

One time, I noticed a friend who had been writing about how he was "always up for an adventure" actually started trying out the things he would not dare before due to his public image.

2. Feedback loops reinforce specific traits

Once your profile is live, people respond to it. They comment on certain things. They ask about specific interests. If you mention that you're a reader, people ask what you're reading. If you describe yourself as adventurous, people ask about your latest trip.

According to Pew Research Center, 74% of U.S. adults with close friends connect at least a few times a week through texting and social media. That's a lot of ongoing feedback. And over time, this feedback starts to reinforce certain parts of your identity while others fade into the background.

I've observed this in how people describe themselves over time. The traits that get the most positive response tend to become more central to their self-image. The traits that go unnoticed tend to shrink. If nobody ever asks about your interest in cooking but everyone comments on your travel photos, cooking gradually slides off your self-description — even if you still enjoy it. Your identity starts to be shaped by what other people respond to, not just by what you care about.

3. You start editing out the complicated parts

Profiles reward simplicity. You have a limited space to make an impression, so you trim. You smooth out the contradictions. You present a coherent, easy-to-understand version of yourself.

The problem is that people aren't coherent or easy to understand. We're messy. We hold conflicting opinions. We like things that don't go together. We're serious and silly, ambitious and lazy, confident and uncertain — sometimes all in the same afternoon.

When you repeatedly present a simplified version of yourself, you can start to lose touch with the complexity. I've seen people describe themselves the same way for years — using the same bio language, the same photos, the same framing — and gradually become a flatter version of who they actually are. The messy, contradictory parts that make someone interesting get left on the cutting-room floor because they don't fit neatly into a profile box.

A survey from the U.S. Census Bureau (2023) found that around 117.6 million U.S. adults are unmarried. Many of them are on platforms where self-presentation is constant. That's a lot of people engaged in ongoing identity curation — a process that shapes how they see themselves, whether they realize it or not.

4. The gap between profile and self creates tension

This is the flip side of point one. Sometimes, instead of growing into the profile, people feel the distance between the profile and their everyday self. And that gap creates discomfort.

If your profile says you're outgoing, but you actually prefer quiet evenings at home, every interaction that references your social personality feels a little off. If your photos show the best version of a specific moment, daily life can start to feel underwhelming by comparison.

I think this tension is more common than people admit. The profile becomes a standard they feel they need to live up to. And when they can't, it doesn't feel like the profile was inaccurate — it feels like they're falling short. That's a subtle but important distinction. The profile was supposed to represent them, but it ends up judging them instead.

This tension is especially sharp when meeting new people online. You present one version of yourself in the profile, and then the conversation begins, and you have to live up to it in every message. If the profile version feels far from the everyday version, that conversation can feel exhausting — like performing a character instead of just being yourself.

What I take away from all of this

I'm not saying profiles are harmful. They're necessary. If you're going to participate in online spaces — especially if you're meeting new people online — you need some way to introduce yourself. A profile is that introduction.

But I think it's worth being aware of what the profile is doing to you, not just for you. The version of yourself you put out there isn't neutral. It's active. It shapes what people expect from you, what feedback you receive, and — over time — what you expect from yourself.

The people I've observed who seem most comfortable online are the ones who update their profiles to match their current selves, rather than trying to match themselves to an outdated profile. They let the description follow reality, not the other way around. They're comfortable showing the messy, evolving version of who they are — and that honesty tends to attract better conversations and better connections anyway.

Your profile is a tool. Make sure you're the one using it — not the other way around.
