The Lie the Character Believes

Main Street Writes Group Discussion — Originally presented May 18, 2026

Why do characters make decisions that seem so obviously wrong to everyone around them?

Why do they push away the people who love them, refuse help when they desperately need it, or continue pursuing something that’s clearly making them miserable?

Sometimes the answer isn’t simply that they’re stubborn, proud, or afraid.

It’s that they believe something about themselves or the world that isn’t true.

And that false belief can shape everything they do.

In this week’s writers’ group discussion, we’re exploring what storytellers sometimes call The Lie the Character Believes—and how challenging that lie can become the foundation of a powerful character arc.

1. Core Idea: The Lie Beneath the Character

Many compelling characters carry a belief that shapes the way they see themselves and the world.

For example:

• “I have to handle everything alone.”
• “If people really knew me, they’d reject me.”
• “Power is the only thing that keeps people safe.”
• “Loving someone only leads to pain.”
• “My past defines who I am.”

These aren’t necessarily conscious lies.

The character isn’t deliberately deceiving anyone.

They may sincerely believe these things to be true.

In fact, that belief may have helped them survive some difficult experience earlier in their lives.

But now it’s limiting them.

It’s affecting their relationships, influencing their choices, and preventing them from seeing possibilities they might otherwise recognize.

The lie is a false or incomplete belief that the character treats as truth.

And one of the most interesting things a story can do is put that belief under pressure.

2. How the Lie Connects to Wants, Needs, and Flaws

In our previous discussions, we explored three important elements of character development:

Want: What the character consciously pursues.

Need: What the character must recognize or change.

Flaw: The weakness that creates problems and complicates the character’s journey.

Now let’s add the lie.

Imagine a character who wants to become a powerful leader.

Their want is to gain authority.

Their need is to learn to trust others.

Their flaw is an inability to delegate or accept help.

But underneath all of that is a belief:

“Depending on other people makes me weak.”

That’s the lie.

And look at what happens because of it.

They refuse advice.

They push away loyal allies.

They insist on making every important decision themselves.

Eventually, their inability to trust others leads to a disastrous mistake.

The lie has created the flaw.

The flaw has influenced the choices.

And the choices have created the conflict.

That’s how an internal belief becomes an external plot.

3. Why Characters Protect Their Lies

Here’s something important.

Most characters don’t immediately question their false beliefs.

They defend them.

They rationalize them.

They find evidence that supports them.

And when someone offers a different perspective, they may become angry or defensive.

Why?

Because the lie often feels safer than the truth.

Imagine someone who believes:

“Everyone I love eventually leaves me.”

Perhaps they experienced abandonment as a child.

Now, whenever someone gets close, they become suspicious.

They test the relationship.

They withdraw.

They look for evidence that the other person is going to leave.

And eventually, their behavior pushes that person away.

What happens next?

The character tells themselves:

“See? I knew they’d leave.”

Their false belief has become a self-fulfilling prophecy.

The lie creates the very circumstances that seem to prove it true.

That’s an extraordinarily useful tool for creating character-driven conflict.

4. The Lie in Popular Stories

Some of the most memorable characters in movies and television are shaped by false beliefs they must eventually confront.

Eleven — Stranger Things

The Lie: “I’m a monster.”

Want: Find belonging and protect the people she cares about.

Need: Recognize that her abilities and traumatic experiences do not define her worth.

Eleven grows up being treated as an experiment rather than a person.

She’s isolated, controlled, and repeatedly made to feel that her extraordinary abilities make her dangerous.

It’s understandable that she begins to question whether she’s fundamentally different from—and perhaps less worthy than—everyone else.

But that belief affects her ability to trust others and accept herself.

Her relationships with Mike, Hopper, and her friends repeatedly challenge the idea that she’s merely a weapon or a monster.

Her struggle isn’t just against the supernatural threats surrounding her. It’s also against the way she’s learned to see herself.

Simba — The Lion King

The Lie: “I’m responsible for my father’s death.”

Want: Escape his painful past and live without responsibility.

Need: Confront the truth, accept his identity, and reclaim his place in the world.

Simba is a particularly clear example because someone deliberately plants the lie.

Scar manipulates him into believing that Mufasa’s death was his fault.

Simba accepts that belief.

And because he believes it, he runs away.

He abandons his responsibilities, avoids his past, and builds an entirely different life.

But the lie never stops influencing him.

When he eventually returns, he must confront not only Scar but also the guilt and shame that have shaped his decisions for years.

His internal conflict is inseparable from the external story.

Without that false belief, Simba’s journey would unfold very differently.

Will Hunting — Good Will Hunting

The Lie: “If people get close enough to know me, they’ll eventually hurt or reject me.”

Want: Maintain his independence and control over his life.

Need: Accept vulnerability, trust others, and stop allowing his past to determine his future.

Will is extraordinarily intelligent.

He can solve mathematical problems that leave brilliant academics struggling.

But emotional intimacy is another matter entirely.

He uses sarcasm, confrontation, and intellectual superiority to keep people at a distance.

When someone begins getting too close, he creates conflict.

He’d rather damage a relationship himself than risk being abandoned.

His intelligence isn’t the problem.

It’s the way he uses that intelligence to protect a belief about himself and other people.

His relationship with Sean, his therapist, gradually forces him to confront truths he’s spent his life avoiding.

And what makes the story compelling isn’t simply whether Will achieves professional success.

It’s whether he can stop protecting himself long enough to allow someone else into his life.

George Bailey — It’s a Wonderful Life

The Lie: “My life hasn’t amounted to anything.”

Want: Escape Bedford Falls, pursue his ambitions, and accomplish something extraordinary.

Need: Recognize the value of the life he’s already lived and the difference he’s made to others.

George Bailey dreams of travel, adventure, and great achievements.

But one responsibility after another keeps him in Bedford Falls.

As the years pass, he begins to see his life as a series of missed opportunities.

When everything seems to collapse, he becomes convinced that his existence hasn’t mattered.

The story challenges that belief by showing him what the world would look like if he’d never been born.

And suddenly, George sees something he couldn’t recognize before.

His life has affected countless others in meaningful ways.

The things he considered disappointments were often acts of extraordinary generosity and sacrifice.

His circumstances haven’t magically changed. His understanding of their meaning has.

And that’s the character’s transformation.

5. Same Scene, Two Versions

Let’s see how an underlying lie can change a relatively simple conversation.

Version A: No Underlying Lie

“You should come with us,” Maya said.

“No,” Ethan replied.

“Why not?”

“I just don’t want to.”

The exchange establishes that Ethan doesn’t want to join the others.

But we don’t learn very much about him.

His decision could be based on almost anything.

Now let’s give him a false belief that’s influencing his behavior.

Version B: The Lie Drives the Scene

“You should come with us,” Maya said.

Ethan kept packing his bag. “You’re better off without me.”

“That’s not true.”

“Last time people trusted me, they died.”

“That wasn’t your fault.”

He laughed once. Sharp. Bitter.

“Keep telling yourself that.”

Now we have something different.

Ethan doesn’t simply want to be alone.

He believes that allowing others to depend on him will lead to their suffering.

Whether that’s actually true is another matter.

But he believes it.

And that belief shapes his response to Maya.

It creates resistance.

It damages their relationship.

And it may prevent him from getting the help he needs.

Notice how much more interesting the scene becomes when Ethan has a reason for his behavior—even if that reason is based on something he doesn’t fully understand.

6. How the Lie Creates Turning Points

Think back to our earlier discussion, Every Scene Needs a Turn.

A scene becomes meaningful when something changes.

One particularly effective kind of turn occurs when a character’s false belief is challenged.

Imagine a woman who believes she can only rely on herself.

Throughout the story, she refuses help.

She succeeds often enough that her belief seems justified.

Then something happens.

She makes a mistake that nearly costs someone their life.

For the first time, she needs help and cannot solve the problem herself.

An ally steps forward.

Now she faces a choice.

Accept the help and question everything she’s believed…

or reject it and risk making the situation even worse.

That is a meaningful scene turn because it challenges both the character’s external goal and her internal worldview.

But here’s what can make the story even more compelling.

She might still reject the help.

She might double down on the lie.

And that decision could create an even bigger problem.

Character growth doesn’t always happen the first time the truth appears.

Sometimes the character must experience the consequences of resisting it repeatedly.

7. A Quick Writing Exercise

Choose one of your characters and answer these questions:

1. What false belief does the character hold? What do they believe about themselves or the world that may not actually be true?
2. Where did that belief come from? Was it shaped by childhood, trauma, disappointment, betrayal, or something they misunderstood?
3. How does the belief affect their behavior? Consider their relationships, dialogue, decisions, and reactions under pressure.
4. What truth do they need to recognize? What would change if they stopped believing the lie?

Now try a short writing exercise.

Write a line of dialogue in which the character reveals their false belief without directly explaining it.

For example, someone who believes people always abandon them might say:

“Don’t worry. I wasn’t expecting you to stay.”

Or someone who believes they must never show weakness might say:

“I don’t need anyone’s help.”

The point isn’t to announce the lie to the reader.

It’s to let the belief influence the way the character speaks and behaves.

8. Does Every Character Have to Overcome Their Lie?

Not necessarily.

Some characters recognize their false beliefs and change.

Others recognize them but cannot bring themselves to act differently.

And some characters never recognize the truth at all.

That’s one of the differences between a redemptive character arc and a tragic one.

A character who abandons their false belief may become wiser, healthier, or more capable of meaningful relationships.

A character who clings to it may destroy those relationships—or even destroy themselves.

And some stories aren’t really about transformation at all.

The point isn’t that every protagonist must experience a life-changing revelation.

It’s that understanding what a character believes can help us understand why they make the choices they do.

And those choices are what shape the story.

Closing Thought

The lie a character believes doesn’t have to be dramatic.

It might be something as ordinary as:

“I’m not good enough.”

Or:

“If I ask for help, people will think less of me.”

But if that belief influences how the character behaves, it can create conflict throughout an entire story.

It can explain their flaws.

Shape their dialogue.

Complicate their relationships.

And eventually force them into decisions that determine who they become.

So when developing a character, it’s worth asking:

What does this person believe that might not be true?

And perhaps more importantly:

What would it take for them to finally question it?

Because sometimes the greatest obstacle a character must overcome isn’t another person, a dangerous situation, or an impossible task.

It’s a belief they’ve carried for so long that they’ve mistaken it for the truth.
