When Smart Characters Are Written Like They Aren’t: A Writing Mistake in The Resident and When the Phone Rings

There is a particular kind of writing mistake that can make me stop watching a story for a moment and think:

“Wait… why are you doing that?”

Not because the character made a mistake.

Characters are supposed to make mistakes. They can panic, miscalculate, misunderstand a situation, trust the wrong person, or simply make a bad decision.

That is human.

What bothers me is something different: when a character who has been established as intelligent suddenly stops thinking like themselves because the plot needs them to.

And once you notice it, it becomes very difficult to ignore.

There’s actually a name for this: the “Idiot Ball.” The term describes the moment when a normally competent character suddenly becomes inexplicably incompetent because the story needs them to make a particular mistake. When this happens repeatedly — especially when multiple characters have to behave this way to keep the story moving — we get what’s often called an “Idiot Plot.” It’s the kind of story that could be resolved in minutes if the characters simply did the obvious thing.

Film critic Roger Ebert famously used the term Idiot Plot throughout his reviews, describing stories whose conflicts exist largely because the characters refuse to do what any reasonable person would immediately do.

And honestly, I think this is one of the most frustrating problems a writer can create.

Because the audience is willing to believe that a character can fail.

What the audience struggles to believe is that a character will suddenly stop being themselves.

I noticed this particularly strongly in two very different dramas: The Resident and the Korean drama When the Phone Rings.

And interestingly, they demonstrate two different sides of the same problem.

🧠 Intelligence Is Part of Characterization

When you write an intelligent character, intelligence isn’t just a label you put in their biography.

You have to actually write them as intelligent.

If you tell me that a character is a brilliant doctor, an experienced investigator, an expert hacker, or someone who is exceptionally good at reading people, I will accept that.

But then I expect their intelligence to affect the way they behave.

They should notice things other characters don’t.

They should consider possibilities.

They should make connections.

They should sometimes surprise me.

And most importantly, when they make a mistake, I should understand why they made it.

That last part is important.

I don’t need my characters to be perfect.

In fact, perfect characters are boring.

But there is a huge difference between:

“This character made a mistake because they were scared.”

and:

“This character made a mistake because otherwise there wouldn’t be an episode.”

The first one develops the character.

The second one exposes the writer.

🏥 The Resident: When Competent Doctors Suddenly Stop Thinking

I usually enjoy medical dramas.

So when I started The Resident, I was interested in its premise and especially in its main character: a doctor presented as exceptionally intelligent, rebellious, independent, and highly perceptive.

And that’s exactly why the writing frustrated me.

When you tell me that your protagonist is brilliant, you are making a promise.

You are telling me that this character sees things other people miss.

That means the challenges you give them have to be worthy of that intelligence.

You need intelligent opponents.

You need complicated situations.

You need problems that cannot be solved by simply noticing the obvious.

What you cannot do is make your protagonist suddenly stop being intelligent because the plot needs another episode.

And that is exactly how I felt watching The Resident.

“Just Take Out Your Phone!”

One scene made this particularly obvious.

A senior doctor is pretending to perform surgery while another surgeon is actually doing the procedure behind a closed door.

The protagonist discovers what is happening.

He sees it.

He understands what he is looking at.

And then…

Nothing.

He doesn’t record it.

He doesn’t take a photograph.

He doesn’t call anyone.

He doesn’t gather evidence.

He doesn’t even seem to consider the most obvious solution available to literally everyone in the room:

Take out your phone.

I remember watching this and thinking:

“Just record it!”

That’s it.

That is the scene.

And the problem isn’t that the character failed to think of some incredibly sophisticated plan.

The problem is that the solution is so ordinary that it feels almost impossible for the character to overlook it.

This isn’t a case of a character being under pressure and making a bad decision.

The story has constructed a character who is supposed to be exceptionally intelligent — and then temporarily removed that intelligence so the plot can continue.

And that is where I lost interest.

Because the scene actually had the potential to create a much more interesting story.

Imagine if he had recorded the surgery.

Now you have evidence.

Now you have leverage.

Now you can introduce blackmail, manipulation, retaliation, cover-ups, power struggles, and competing interests.

Suddenly, the corrupt doctor has a genuinely dangerous opponent.

That’s interesting.

Instead, the conflict has to continue because the smartest person in the room apparently forgot that smartphones have cameras.

Give Me a Reason

That creates a strange disconnect.

I’m not sitting there thinking:

“Wow, what a clever villain.”

I’m thinking:

“Wait. How did nobody think of this?”

And that distinction matters.

If the writers had established a believable reason why the characters couldn’t identify what was happening, I would have accepted it.

Maybe the evidence was deliberately manipulated.

Maybe the information available to them was incomplete.

Maybe they were under extreme emotional pressure.

Maybe the antagonist was genuinely smarter than they were.

Any of those possibilities could work.

But simply making the doctors overlook something because the plot needs them to overlook it?

That’s where the story starts asking me to carry the Idiot Ball for it.

📱 When the Phone Rings: The Phone Problem

And then my cousin recommended a South Korean drama called When the Phone Rings.

And once again, I found myself sitting in front of the screen thinking:

“You cannot be serious.”

The male protagonist is presented as highly intelligent, powerful, respected, and extremely difficult to fool.

His wife, meanwhile, is supposedly unable to speak because of selective mutism.

Then she is kidnapped.

The kidnapper begins threatening the husband over the phone.

Except there is one small problem.

The person making those calls is actually his wife.

And she can speak perfectly well.

Fine.

That is the premise.

I can work with that.

But then comes the scene that made me question everything.

The Phone Is Right There

During one of the threatening calls, the husband goes to a rooftop.

His wife is there.

And he sees her holding a phone.

Not just any phone.

A phone with a black case and a bright red stripe.

The phone is visibly different from her own white phone — a phone he had specifically asked to check earlier.

So he already knows what her phone looks like.

He knows someone is threatening him.

He knows the threatening calls are coming from a specific phone.

He is standing next to the woman who supposedly cannot speak.

And he sees her holding a completely different phone.

At this point, I don’t need him to solve an international conspiracy.

I don’t need Sherlock Holmes.

I need him to look at the phone and think:

“Wait.”

That’s it.

Check the bag.

Take the phone.

Ask where it came from.

Do something.

And yes, I understand that grabbing someone’s bag is invasive.

But we’re talking about a person who is potentially threatening your life and your wife’s life.

We’re allowed to be a little impolite here.

Instead, the plot moves forward because he doesn’t make the connection.

Again, the issue isn’t that he missed an incredibly subtle clue.

The clue is practically glowing.

📱 When the Phone Rings: The Problem Gets Even Stranger

When the Phone Rings gave me another example of this problem — but also an important counterexample.

The female protagonist.

She is often written as quiet, withdrawn, and non-confrontational.

At first glance, that could easily become another example of a character being artificially passive because the plot needs her to be.

But I actually think the show gives us enough context to understand her behavior.

She has experienced trauma.

She has learned to survive by avoiding confrontation.

She is written as someone who has become accustomed to being quiet rather than someone who simply doesn’t know how to act.

And only in moments of extreme danger — particularly during the kidnapping — does she find the courage to confront the person threatening her.

That distinction is incredibly important.

Her lack of action isn’t necessarily stupidity.

It is characterization.

Her trauma explains why she doesn’t immediately behave like the perfect action heroine.

And that’s exactly what I want from a story.

Give me a reason.

If a character doesn’t act, show me why.

If they’re afraid, let me feel their fear.

If they’re traumatized, let that trauma influence their decisions.

If they’re confused, make the confusion believable.

Don’t just make them stupid.

💻 But Then… The Hacker Has No Password?

And then we get to the kidnapper.

This is where I genuinely started asking questions.

The kidnapper is presented as someone who is highly capable with technology. He hacks the car, takes control of it, and navigates it toward himself.

So we’re talking about someone who is supposed to be, essentially, a hacker genius.

And then she takes his phone.

And there is…

No password.

Nothing.

No lock.

No security.

Just the phone sitting there, apparently containing potentially important evidence.

And I remember thinking:

You are supposed to be a hacker.

You’re telling me this man can remotely hack a car, but he can’t put a password on his phone?

Again: this isn’t about expecting characters to be perfect.

A hacker can absolutely make a mistake.

But if the character’s entire identity is built around being technologically sophisticated, the mistake has to make sense within that characterization.

Otherwise, the writers have built a powerful character and then immediately weakened him because the heroine needs his phone.

And that’s the problem I’m talking about.

🎭 Don’t Weaken the Character. Make the Conflict Stronger.

This is where I think writers sometimes take the easiest possible route.

They create a powerful character.

Then they realize:

“Okay, how is our protagonist supposed to beat them?”

And instead of making the protagonist smarter, they make the antagonist dumber.

Instead of finding a believable weakness, they simply remove the antagonist’s competence.

Instead of allowing the characters to struggle, they give them a convenient solution.

But there is another way to write this.

Make their enemies stronger.

If the protagonist is brilliant, give them an opponent who is even harder to outsmart.

If the villain is a genius hacker, let the protagonist need several attempts to get into their system.

Let them make a mistake.

Let them try something that doesn’t work.

Let the villain anticipate them.

Let the solution take time.

That creates drama.

Because now I am not watching the story waiting for the characters to become stupid.

I’m watching them try to outthink each other.

And that’s much more interesting.

🧩 Failure Is Not the Problem

And I want to make something clear here, because this is where the criticism of “Idiot Plot” can sometimes become unfair.

Smart people make stupid decisions.

Of course they do.

Characters are allowed to fail.

In fact, they should.

A detective can miss a clue because they are emotionally involved.

A doctor can misdiagnose someone.

A lawyer can make a terrible judgment call.

A genius can make a terrible decision — or forget something incredibly obvious.

A hacker can make a mistake.

A traumatized woman can freeze when she should run.

None of those things automatically make a story badly written.

That’s not bad writing by itself.

The question is whether the mistake makes sense for the character and the circumstances.

If a character is terrified, distracted, emotionally overwhelmed, or working with incomplete information, I can accept a mistake.

What I struggle with is when the character has all the information, all the tools, all the time — and simply doesn’t do the obvious thing because otherwise there would be no plot.

That’s not human imperfection.

That’s the writer holding the Idiot Ball.

Does the failure belong to the character, or does it belong to the plot?

If the failure comes naturally from who the character is, it can deepen the story.

If the failure exists only because the writer needs the next scene to happen, the audience can feel it.

And once I can see the writer moving the pieces around, the illusion breaks.

🎌 What Anime Gets Right About This

Part of why this issue stands out to me comes from what I grew up watching.

I grew up with two older brothers, and between all the teasing, there were always anime shows playing on television.

Many of those stories focused heavily on complex relationships between heroes and villains.

The conflict was not just physical.

It was psychological.

The protagonist and antagonist challenged each other’s beliefs, intelligence, and emotions.

The enemy was not simply “the bad guy.”

They were someone who forced the hero to become better.

And I think that is something many modern shows could learn from.

In a world where everyone has a phone, security cameras are everywhere, and information can spread instantly, antagonists and conflicts need to become more sophisticated.

The solution is not making characters act less intelligent.

It is creating smarter challenges.

The thing anime often does extremely well is allowing intelligent characters to remain intelligent even when they lose.

Take a character who is established as a strategic thinker.

If they lose a battle, the story doesn’t necessarily make them suddenly stupid.

Instead, their opponent might simply be smarter.

Or they miscalculated.

Or they didn’t have enough information.

Or their emotional attachment to someone affected their judgment.

Or they understood the situation correctly but made the wrong choice anyway.

That creates much more satisfying conflict.

Because the audience can look back and say:

“Oh. I understand why they lost.”

Not:

“Why didn’t they just do the obvious thing?”

And anime often goes even further by building entire relationships around intellectual competition.

The characters learn from each other.

They adapt.

They anticipate.

They make plans within plans.

And sometimes the smartest character still loses.

But they don’t have to become an idiot in order for someone else to win.

❤️ Relationships Should Create Conflict — Not Flatten It

And this applies to character relationships too.

One of the things that frustrates me most when writing becomes too plot-driven is when relationships are flattened just to move the story from one event to another.

If two intelligent characters have a complicated relationship, don’t make one of them suddenly misunderstand everything simply because the writers need a misunderstanding.

If two characters are trying to solve a problem together, let them actually communicate.

And if they don’t communicate, give me a reason.

Maybe they don’t trust each other.

Maybe they’re afraid of the consequences.

Maybe one of them is hiding something.

Maybe they genuinely don’t know what the other person is thinking.

Those are conflicts.

“They could have solved this by talking for five minutes” isn’t conflict.

It’s a delay.

And that’s exactly where the Idiot Plot becomes frustrating.

🛠️ So How Do You Create Tension Without Making Characters Stupid?

There are so many better options.

Make the enemy smarter.

If your protagonist is extremely capable, don’t reduce their intelligence. Give them an opponent who can actually challenge them.

Give the protagonist incomplete information.

They don’t need to know everything. Maybe they make the wrong decision because they genuinely don’t have enough information.

Create conflicting priorities.

Maybe the smart choice is also the emotionally painful choice.

Now the character has a real dilemma.

Let solutions take time.

Not every problem needs to be solved immediately.

Sometimes the most satisfying part of a story is watching characters slowly put the pieces together.

Let characters make believable mistakes.

Fear, trauma, love, anger, exhaustion and desperation can all affect judgment.

But show us that.

And most importantly: let characters remain themselves.

If you’ve spent ten episodes establishing that someone is brilliant, don’t turn them into an idiot in episode eleven just because you need a plot twist.

🎬 The Audience Isn’t Asking for Perfect Characters

I think sometimes writers are afraid that if their characters are too intelligent, there won’t be enough drama.

But I actually think the opposite is true.

Intelligent characters create better drama when the writing respects their intelligence.

If everyone is competent, the conflict becomes more interesting.

Now the question isn’t:

“Why didn’t they just figure this out?”

It’s:

“Who is going to figure it out first?”

That’s a much more exciting question.

And if the answer is the villain?

Even better.

Because then the protagonist has to grow, adapt, or find a completely different way forward.

🎬 Final Thoughts

Both The Resident and When the Phone Rings reminded me of something I think writers sometimes forget:

A character’s intelligence is part of their identity.

You can’t simply switch it off when the plot needs a shortcut.

And I’m not saying characters shouldn’t make stupid decisions.

People make stupid decisions all the time.

I’m saying that the story needs to understand why this particular character would make that particular mistake.

Because there is a huge difference between a character failing and a character being written to fail.

One creates drama.

The other creates frustration.

And honestly, if you have built a powerful character, don’t be afraid of what happens when they actually behave like the person you told us they were.

Don’t weaken your characters just to move the plot forward.

Make their enemies stronger.

Deepen their relationships.

Give them harder choices.

Let them fail for reasons that belong to them.

And most importantly, let them think.

There is so much to learn from anime and from the depth of relationships you can find there.

Because a person isn’t a robot, and solutions don’t always appear in front of them at exactly the second they need them.

But if finding the right move takes time, show me that process.

That’s not a problem with the story.

That’s the story.
