Why Your Teenager Cares So Much About What Everyone Thinks

Have you ever wondered why your teenager seems to care so much about what everyone else thinks? 

There's neuroscience behind that, but there's another phenomenon that all of us are susceptible to—and our teenagers are getting it straight to the face nearly every second of every day.

Collective illusion.

If you haven't heard of the phenomenon before, don't confuse it with folie à deux, a shared delusion between two or more people. Collective illusion is something different.

It's a social phenomenon where most people privately believe one thing, but publicly act as if they believe something else because they think everyone else believes it.

When I was in sixth grade, I publicly professed to despise the Backstreet Boys.

Why?

Because I wanted to fit in with the kids at my math table - plus, one of the guys was really cute.

Meanwhile, the second I got home, I put their debut album on repeat until bedtime. I knew every lyric. I pored over the full-page spreads in Teen Beat. I absolutely loved the Backstreet Boys.

But I would never have admitted it.

I didn't want to risk not belonging. At twelve years old, I was convinced that admitting I liked the "wrong" boy band might be the nail in the coffin socially.

The result?

Everyone reinforces a reality that almost nobody actually believes—or that only a small subset of people believe, not the majority, and certainly not everyone.

Psychologists have been studying this phenomenon for nearly a century, giving it names like pluralistic ignorance and preference falsification. Whatever we call it, the result is the same: people begin living according to beliefs they assume everyone else holds, even when those beliefs aren't actually shared by the majority.

So how did psychology arrive at this conclusion?

One of the classic examples comes from a 1928 social study of a small New York village called Elm Hollow.

Elm Hollow was a close-knit community with what most people would describe as very traditional—or arguably Puritan—values.

No drinking.

No dancing.

No playing cards.

Especially face cards.

And yet...

Within a month of arriving in Elm Hollow, researcher Richard Schnack had played cards with nearly everyone in town.

Privately.

In their homes.

Often with whiskey sitting on the table.

So why did everyone publicly profess that these activities would "let in the Devil," while privately participating in them? Because everyone believed their neighbors believed it.

No one wanted to be the first person to admit otherwise. The illusion sustained itself.

How did they all get this idea? That largely came down to one woman. Mrs. Salt—a pseudonym used in the research for the town matriarch.

Mrs. Salt genuinely held those beliefs, and she made sure the new preacher knew exactly where she stood. Because she was the loudest voice in town, everyone else assumed she represented everyone.

She didn't. When Mrs. Salt eventually passed away, something fascinating happened. People slowly began expressing what they had privately believed all along.

The illusion cracked.

Not because anyone's beliefs suddenly changed... but because people finally realized they had never been alone.

Teenagers Live Inside Collective Illusion 

Your child isn't simply developing their identity, though that would be hard enough. They're developing their identity while surrounded by hundreds of other teenagers who are also trying to figure out who they are—and many of them are pretending they've already figured it out. It's the blind leading the blind.

Most teenagers are convinced that everyone else knows what they're doing.

The reality?

Almost nobody does.

Take Instagram as an example. Everyone posts the vacation, the best picture of their body, the perfect relationship, the cutest outfit, the acceptance letter. Looking at that highlight reel, it's easy to think, "I'm the only one struggling." When in reality, everybody is struggling with something.

During my years as a high school teacher, I watched this happen every single day. Students laughed at jokes they didn't actually find funny, pretended to like trends they secretly thought were ridiculous, pretended they didn't care about their grades, pretended they were confident, pretended they didn't need friends, pretended they already knew what they wanted to do with their lives, and most of all...pretended they were fine.

When everyone around you appears confident, it's incredibly difficult to be the first person to admit, "Actually...I'm not okay here." Because if everyone else seems fine, admitting you're struggling feels like volunteering to become the odd one out.

So the performance continues.

Imagine your child looking around the classroom and thinking, "Everyone else seems confident." The conclusion becomes, "I must be the only one who's anxious." So they hide the anxiety. Everyone else does the same.

The illusion grows.

Nobody intended to lie.

Yet everyone participates.

Borrowed Identities

Teenagers spend much of adolescence asking one enormous question:

Who am I?

But instead of answering that question through experience, they often answer it through comparison.

"I must be..."

...and then they fill in the blank with everything they believe they're lacking compared to everyone else. Everything they're "supposed" to be.

That's not identity.

That's adaptation.

I actually think one of the greatest dangers of collective illusion is that it creates what I call borrowed identities. Students slowly begin believing things about themselves that were never actually theirs to begin with—not because they're true, but because they were surrounded by other people who were also trying to fit in.

Comparison isn't just about self-esteem or self-confidence. The real problem is that we're comparing our insides to everyone else's outsides. We're making conclusions about ourselves using evidence that doesn't actually exist. 

School amplifies this without intending to.

Grades.

Honor Roll.

Sports.

Popularity.

College admissions.

Awards.

AP classes.

Leadership.

School constantly provides visible status markers.

Meanwhile, the traits that actually determine the quality of a person's life—kindness, courage, curiosity, integrity, resilience—are largely invisible. They don't get posted on the hallway bulletin board or announced over the morning announcements.

So students naturally conclude that the visible things must matter the most.

Not because anyone explicitly taught them that.

Because that's how systems work.

I actually think one of the greatest risks of adolescence isn't making bad decisions.

It's accidentally building an identity around beliefs that were never truly yours in the first place.

Most teenagers spend enormous amounts of energy trying to become the person they think everyone else expects them to be.

Very few stop to ask,

"Does everyone actually expect that?"

Or perhaps an even better question,

"Even if they do...is that who I want to become?"

That question is the beginning of agency.

It's the moment your teenager stops asking, "Who do I have to become so everyone else accepts me?" and starts asking, "Who do I actually want to become?"

That shift changes everything.

At Student Success Lab, we come back to one simple reminder again and again:

The loudest voice in your life isn't always your own.

Becoming yourself begins by learning which voices you've mistaken for your own.

Because the goal isn't to become who everyone else expects you to be.

The goal is for your teenager to  become who they choose to become.

If This Resonated... 

If you found yourself thinking,

"That's my child."

Or maybe even,

"That was me."

Then I'd love to invite you to something special.

The Student Success Reset is a free workshop for parents and students who are ready to stop treating behaviors like procrastination, anxiety, perfectionism, and self-doubt as character flaws—and start understanding what's really happening beneath the surface.

Together, we'll explore why students get stuck, how identity is formed, and what actually helps teenagers build confidence, resilience, and ownership over their own lives.

If today's article gave you a new way of looking at your child, imagine what two hours together could do.
