You got the job.

You earned the degree.

People ask for your opinion.

Clients come back. Colleagues respect you. Someone has apparently decided that you should be in charge of something.

There is actual evidence that you know what you're doing.

And yet, some part of you remains unconvinced.

If they really knew how much I don't know...

I got lucky.

Anyone could have done that.

Eventually they're going to realize I'm not as good as they think I am.

This experience is often called impostor syndrome.

But that name may make it sound more straightforward than it actually is.

First: this isn't a diagnosis

“Impostor syndrome” has become part of everyday language, but it isn't a psychiatric diagnosis.

Researchers more often refer to the impostor phenomenon or impostor feelings, and even the research literature doesn't entirely agree about how the experience should be defined or measured.

What does seem clear is that impostor feelings can persist despite clear evidence of competence and accomplishment.

That's the interesting part.

If you truly lacked experience, feeling uncertain wouldn't be particularly mysterious.

But what happens when you've accumulated years of evidence and the evidence still doesn't seem to change something inside?

You may be comparing your insides with everyone else's outsides

You know exactly how you produce your own work.

You know about the false starts.

The things you had to look up.

The moment you stared at the screen thinking, I have absolutely no idea what I'm doing.

You know which parts were difficult.

You know every mistake that almost happened.

You know when you were improvising.

Then you look at someone else's finished product.

Of course the comparison is unfair.

You have access to your entire backstage operation and only their performance.

Competence rarely feels from the inside the way it looks from the outside.

Expertise can actually make uncertainty more visible

There is another paradox.

As you become more knowledgeable, you may become increasingly aware of what you don't know.

A beginner can sometimes feel quite certain because the complexity of the field isn't yet visible.

An experienced person sees exceptions.

Context.

Trade-offs.

The limits of the evidence.

The cases where the usual answer doesn't apply.

So uncertainty isn't always evidence that you're unqualified.

Sometimes it's evidence that you understand the problem well enough to know it isn't simple.

Success may not update an older understanding of yourself

But there can be something deeper going on.

Suppose you developed an understanding of yourself early in life:

I'm not the smart one.

I have to work harder than everyone else.

Other people know what they're doing.

If I make a mistake, people will realize I'm not good enough.

Then adulthood provides contradictory evidence.

You become successful.

Other people trust you.

You develop expertise.

You may even become the person younger colleagues turn to because you seem to know what you're doing.

Intellectually, you can recognize all of this.

But an older emotional understanding of yourself may not automatically revise itself just because new evidence has arrived.

That's one reason telling yourself, Look at everything you've accomplished, may help briefly without resolving the feeling.

You already know what you've accomplished.

That's not necessarily where the problem lives.

Perfectionism makes an excellent accomplice

If your standard for genuine competence is never being uncertain, you're going to feel fraudulent surprisingly often.

Real expertise doesn't eliminate mistakes.

It doesn't eliminate consultation.

It doesn't eliminate preparation.

It certainly doesn't eliminate learning.

But perfectionism can quietly redefine all of those ordinary parts of competent work as evidence of inadequacy.

If I were really good at this, I wouldn't have had to prepare so much.

If I really belonged here, I wouldn't feel nervous.

If I were truly an expert, I'd know the answer immediately.

Notice the standard.

You're not comparing yourself with another competent human being.

You're comparing yourself with an imaginary person who never doubts, struggles, forgets, checks, consults, or learns.

That person has one considerable professional advantage over you:

They don't exist.

Maybe feeling competent isn't the prerequisite

Many people wait for an internal feeling of certainty to confirm that they belong.

Perhaps the order is backwards.

You may already belong.

You may already be competent.

You may already have earned the position you're in.

The feeling may simply be lagging behind.

That doesn't mean ignoring legitimate limitations. Healthy confidence includes knowing what you don't know, seeking consultation, correcting mistakes, and continuing to learn.

It means allowing uncertainty and competence to exist at the same time.

You don't need to know everything to know something.

You don't need to feel confident every moment to be capable.

And you don't have to eliminate every trace of self-doubt before you're allowed to take your own accomplishments seriously.

What if nobody was fooled?

There is a question worth considering when the familiar thought appears:

Eventually they'll realize I'm not as good as they think I am.

What if the people around you aren't confused?

What if they have been observing you accurately?

They've seen your work.

They've heard what you have to say.

They've watched you solve problems.

They may even know perfectly well that you're human.

And they still trust you.

Perhaps your success isn't evidence that you've become exceptionally good at fooling people.

Perhaps it's evidence.
