Master the art of coherent character choices. Learn why incomprehensible decisions kill reader trust and how to make even irrational choices feel believable and motivated.
The Moment Readers Lose Faith
The setup:
A serial killer has murdered three people connected to the protagonist. The protagonist knows they’re next. They’ve received threatening messages. The police told them to stay vigilant.
The protagonist’s next action:
Goes alone to their regular coffee shop at their regular time, sits with their back to the door, doesn’t check surroundings, thinks about their upcoming vacation instead of the death threat, starts lighthearted conversation with barista about weekend plans.
The reader’s internal monologue:
“Wait, WHAT? There’s a SERIAL KILLER after you and you’re discussing weekend plans? You’re not even looking over your shoulder? This makes no sense. Either the danger isn’t real or this character is an idiot. Either way, I don’t care anymore.”
[Book closed. Reader lost forever.]
What just happened?
The character’s choices violated their established priorities in a way that felt incomprehensible. The writer needed a coffee shop scene, so they moved the character there like a chess piece—without considering whether that choice made ANY sense given everything the character knows and wants.
This is one of the most insidious ways to destroy reader trust:
Making characters choose actions that don’t align with their established priorities, knowledge, and personality—just because the plot requires them to be somewhere or do something.
This guide reveals why character coherence is non-negotiable, how to ensure choices feel motivated even when irrational, and the crucial difference between characters making bad decisions versus incomprehensible ones.
Understanding Coherent Prioritization
The Core Principle
Coherent Prioritization = Character’s choices must make sense based on:
- What they know
- What they want
- Who they are
- What’s at stake
NOT the same as:
- Making the “right” choice
- Being rational or logical
- Avoiding mistakes
- Acting smart
Characters can:
- Make terrible choices (coherently)
- Act on emotion over logic (coherently)
- Be biased, flawed, human (coherently)
Characters cannot:
- Make choices that contradict what they care about (without explanation)
- Ignore obvious priorities (without reason)
- Act out of character (without development)
- Forget crucial information (unless established they would)
The Fiction-Reality Paradox
Reality: People make incomprehensible choices constantly
- Act against their own interests
- Ignore obvious solutions
- Prioritize randomly
- Behave inconsistently
Fiction: Characters making incomprehensible choices breaks believability
Why the difference?
In reality: We don’t know people’s full internal logic In fiction: We’re inside character’s head or following their choices—when those choices don’t track with what we know about them, the illusion shatters
The rule: Fiction must make MORE sense than reality.
Coherent vs. Rational
Critical distinction:
Coherent choice: Makes sense based on character’s values/fears/knowledge Rational choice: Makes logical sense based on best outcome
Example:
Situation: Character’s abusive ex-partner begs for another chance
Rational choice: “No, you abused me, relationship is over”
Coherent but irrational choice: “I know you hurt me. I know you’ll probably hurt me again. But I love you and I can’t imagine life without you, so yes.”
Incoherent choice: Character says yes without any internal struggle, doubt, or acknowledgment of past abuse
The coherent irrational choice works in fiction because we understand the internal logic (love overriding self-preservation) even if we disagree with the decision.
The “Just Use the Thingamabob!” Problem
What It Is
The pattern:
- Character has obvious solution to problem
- Character ignores obvious solution
- Character chooses difficult/dangerous alternative
- No explanation why easy solution won’t work
Why writers do this:
They want character to take the hard path (for drama) but forget to close off the easy path.
Classic Examples
Example 1: The Available Vehicle
Setup: Character needs to cross dangerous desert urgently Easy solution: Character has hyperdrive-equipped spaceship Character’s choice: Rides donkey across desert Reader: “WHY NOT USE THE SPACESHIP?!”
How to fix:
- Spaceship is broken
- Fuel is unavailable
- Using it would alert enemies
- Character doesn’t know how to fly it
- Destination is no-fly zone
Close the easy off-ramp BEFORE character makes hard choice.
Example 2: The Available Expert
Setup: Character needs to understand mysterious artifact Easy solution: Character’s best friend is archaeologist who specializes in this exact thing Character’s choice: Spends weeks researching alone in library Reader: “JUST ASK YOUR FRIEND!”
How to fix:
- Friend is out of country, unreachable
- Friend is angry about unrelated issue, not speaking to them
- Character doesn’t want friend involved in danger
- Character suspects friend might be involved in conspiracy
Example 3: The Available Communication
Setup: Major misunderstanding threatens relationship Easy solution: One honest conversation would clear it up Character’s choice: Months of angst, almost loses relationship Reader: “JUST TALK TO EACH OTHER!”
How to fix:
- Character tried but other person won’t listen
- Character fears vulnerability after past betrayal
- External pressure prevents private conversation
- Character’s pride won’t allow admission of wrong
The pattern: Identify easy solution, make it unavailable or unacceptable to character for coherent reasons.
Contemporary Examples: Coherence Done Right and Wrong
Coherent (Even When Irrational): Gone Girl
Amy’s choices:
Each escalating decision makes sense based on:
- Her narcissistic worldview
- Desire for control and revenge
- Intelligence and planning capacity
- Specific grievances against Nick
Example choice: Framing herself as murder victim is INSANE plan, but coherent because:
- We’ve seen her meticulous planning ability
- We understand her rage at Nick’s infidelity
- We know she values control above all
- Plan aligns with her “Amazing Amy” persona
We understand WHY even when we’re horrified.
Coherent Irrationality: Normal People
Connell’s choices:
Repeatedly chooses social acceptance over relationship with Marianne:
- Won’t invite her to debs (school dance)
- Hides relationship from friends
- Breaks up rather than go public
Irrational? Yes—he loves Marianne, she’s his best relationship Coherent? Completely—we understand his class anxiety, social insecurity, fear of judgment
Rooney shows internal struggle, making irrational choice comprehensible.
Incoherent (Breaks Believability): Common Thriller Mistake
Pattern:
Chapter 3: Protagonist learns killer is targeting them specifically Chapter 4: Protagonist goes jogging alone at dawn in isolated park No internal monologue about risk, no justification, no acknowledgment of danger
Incoherent because:
- Violates survival instinct
- Contradicts established fear
- No reason given for risky choice
- Character not acting like someone in danger
How to fix:
Option A – Explain the choice: “She knew jogging alone was stupid with a killer after her. But she’d run this route every morning for five years. Changing her routine felt like letting him win. Besides, pepper spray was in her pocket, phone in her hand. She’d be alert. Probably fine.”
Option B – Force the choice: “She needed to meet her informant, and he’d only agreed to isolated park at dawn. She considered sending someone else, but only she knew the questions to ask. Risk calculated, accepted.”
Either way, we understand why character makes dangerous choice.
Coherent Mistake: The Kite Runner
Amir’s failure to help Hassan:
Terrible choice? Absolutely—watching friend be raped, doing nothing Coherent? Painfully yes:
- Established cowardice
- Jealousy of Hassan
- Desire for father’s approval
- Hassan just helped him win kite tournament
- Internal monologue shows his rationalization
We understand his failure even while condemning it.
Hosseini shows the internal logic of a terrible choice, making it devastating but believable.
The Priority Violation Patterns
Pattern 1: Danger Ignored
The violation:
Character in mortal danger acts like danger doesn’t exist.
Example:
Serial killer threatened protagonist. Protagonist goes to movies alone, leaves door unlocked, doesn’t tell anyone where they are, thinks about grocery shopping instead of survival.
Why it fails:
Violates basic survival instinct without explanation.
How to fix:
Show why character downplays danger:
- Denial as coping mechanism (show this explicitly)
- Misplaced confidence in security
- Exhaustion from constant vigilance (calculated risk)
- Thinks they’ve figured out pattern (wrong but logical)
Pattern 2: Love Interest Over Everything
The violation:
World-ending crisis, but character prioritizes romance over survival.
Example:
Asteroid hitting Earth in 24 hours. Character spends 20 hours having relationship drama instead of, you know, trying to survive.
Why it fails:
Priority completely misaligned with stakes.
How to fix:
Either:
- Relationship IS survival (they need to coordinate to live)
- Character believes they’re doomed anyway, wants to die with person they love
- Relationship conflict prevents effective collaboration on survival
Make romance and survival interconnected, not competing priorities.
Pattern 3: Information Gathering Delay
The violation:
Character needs crucial information, has easy way to get it, doesn’t even try.
Example:
Character’s sister was murdered. Family friend knows details. Character doesn’t ask them for weeks despite being obsessed with solving murder.
Why it fails:
Contradicts established motivation to solve murder.
How to fix:
- Friend is avoiding character
- Character tried, friend won’t talk
- Character fears what they’ll learn
- Character doesn’t know friend has information
- Asking friend would alert killer
Pattern 4: The Convenient Character Break
The violation:
Character acts completely out of established personality because plot needs them to.
Example:
Risk-averse character who won’t jaywalk suddenly jumps off bridge into raging river with no internal monologue about why they’re overriding every instinct.
Why it fails:
No development explaining change in character.
How to fix:
Show the internal pep talk: “She’d never taken a risk in her life. Jaywalking made her anxious. But her daughter was in that river, and suddenly every cautious bone in her body meant nothing. She jumped.”
Motivation + internal struggle = coherent out-of-character choice
Pattern 5: The Dumb Character Syndrome
The violation:
Character is smart except when plot needs them to be stupid.
Example:
Brilliant detective solves complex crimes. Mysterious figure leaves obvious clues. Detective doesn’t follow up, doesn’t tell anyone, acts like nothing happened because author wants mystery to continue.
Why it fails:
Violates established competence and motivation.
How to fix:
Make smart character’s investigation fail for smart reasons:
- Clues lead to dead ends
- Following them creates new problems
- Character investigates but gets mislead
- Investigation puts others at risk
Smart character trying and failing ≠ Smart character inexplicably not trying
Ensuring Coherent Choices: Practical Techniques
Technique 1: The Priority Hierarchy
For each major character, establish clear priority ranking:
Example hierarchy:
Priority 1: Keep daughter safe Priority 2: Solve father’s murder Priority 3: Maintain job to afford rent Priority 4: Fix failing marriage Priority 5: Personal happiness
Then ensure every major choice respects this hierarchy (unless circumstances force change).
Coherent choice: Opportunity to investigate father’s murder (Priority 2) but would endanger daughter (Priority 1) → Character chooses daughter’s safety
Incoherent choice: Same situation → Character investigates murder anyway with no internal struggle or justification
Technique 2: The “Why Not?” Test
Before finalizing any character choice, ask:
“Why doesn’t character choose the easier/safer/more obvious option?”
If you can’t answer convincingly, you have a coherence problem.
Example:
Choice: Character drives across country instead of flying Why not fly?
- Can’t afford it? (Show financial struggle)
- Fear of flying? (Establish earlier)
- Wanted road trip experience? (Show this desire)
- Bringing dog that can’t fly? (Mention dog)
Pick one and make it clear to reader.
Technique 3: The Character Perspective Journal
When choice feels forced, write scene from character’s perspective:
“Dear Journal, today I decided to [action]. I know it seems [stupid/risky/weird] but here’s why: [actual internal logic].”
If you can’t write convincing journal entry explaining choice, choice is incoherent.
Then add that internal logic to the narrative.
Technique 4: The Close-the-Off-Ramps Checklist
For every difficult choice character makes:
- [ ] What’s the easy alternative?
- [ ] Why isn’t character taking it?
- [ ] Have I made this clear to reader?
- [ ] Does closure make sense given character’s knowledge?
- [ ] Would character really not think of easy option?
If easy option exists and isn’t addressed, fix it.
Technique 5: The Motivation Alignment Check
Before each scene, verify:
- [ ] What does character want most right now?
- [ ] Does their action in this scene pursue that want?
- [ ] If not, why are they prioritizing something else?
- [ ] Is this shift explained to reader?
Actions must align with wants or explanation must be clear.
The Danger Response Problem
Why This Matters Especially
Characters in danger need to act like they’re in danger.
This applies to:
- Physical danger (killers, accidents, disasters)
- Social danger (exposure, humiliation, career destruction)
- Emotional danger (heartbreak, betrayal, loss)
- Existential danger (identity threat, worldview collapse)
What Acting Like Danger Looks Like
Physical danger behaviors:
- Heightened awareness
- Security measures taken
- Escape routes identified
- Trusted people notified
- Paranoia proportional to threat
- Decisions weighted by safety
What it does NOT look like:
- Business as usual
- No mention of threat
- Risky behaviors with no justification
- Forgetting danger exists
The Languid Lunch Problem
The pattern:
Killer is after protagonist → Protagonist has leisurely lunch with parents discussing childhood
Why it fails:
Priority violation. Character acts like danger doesn’t exist.
How to fix:
Option A – Necessity: “She needed to warn her parents without alarming them. Besides, public place felt safer than her apartment. She kept her back to the wall, eyes on the entrance.”
Option B – Denial: “The lunch was her mother’s birthday. Canceling would raise questions. She’d spent three days talking herself into normalcy. Just two hours. What could happen in two hours? (She didn’t let herself answer that.)”
Option C – Strategic: “Meeting her parents served two purposes: solid alibi with witnesses, and her father’s police connections might help without official report.”
Any explanation that shows character hasn’t forgotten the danger.
Genre-Specific Coherence Challenges
Mystery/Thriller
Challenge: Keeping mystery going without making detective incompetent
Solution:
- Smart investigations that hit smart obstacles
- Villain who’s truly clever, not protagonist who’s dumb
- Information revealed then recontextualized
- False leads that seem legitimate
Example: The Silent Patient
Theo investigates competently; he’s misled by his own biases, not by being stupid.
Romance
Challenge: Relationship conflicts that one conversation could solve
Solution:
- Valid reasons why conversation can’t happen
- Character wounds preventing vulnerability
- Miscommunication with clear emotional logic
- External obstacles to communication
Example: The Hating Game
Lucy and Joshua could talk, but pride, competition, and fear of vulnerability prevent it—all clearly established.
Horror
Challenge: Characters making “dumb” choices to create scares
Solution:
- Limited information (character doesn’t know what reader knows)
- Desperation forcing risky choices
- No good options (all choices are bad)
- Psychological state affecting judgment
Better horror: Character makes best choice given knowledge, still goes wrong
Fantasy/Sci-Fi
Challenge: Magic/tech solutions to every problem
Solution:
- Clear limitations on magic/tech
- Costs to using power
- Reasons not to use obvious solution
- Resource scarcity
Example: The Broken Earth trilogy
Magic has severe costs; using it for every problem would destroy user.
Literary Fiction
Challenge: Characters making symbolic but impractical choices
Solution:
- Show internal logic even for symbolic actions
- Character’s psychology makes choice inevitable
- Thematic resonance doesn’t replace motivation
- Choices still track with character’s worldview
Your Character Coherence Audit
Scene-by-Scene Check
For every major character choice:
- [ ] Does character know what reader knows?
- [ ] Given what they know, does choice make sense?
- [ ] Is priority clear (what they want most right now)?
- [ ] Does action pursue priority OR explain why not?
- [ ] Are easy alternatives addressed/closed?
- [ ] Would real person in this situation act this way?
- [ ] Have I shown internal logic?
If you can’t check all boxes, choice needs work.
The Incomprehensibility Red Flags
Warning signs your character’s choices are incoherent:
- [ ] Beta readers ask “why did they do that?”
- [ ] You can’t explain choice without “plot required it”
- [ ] Character forgets crucial information
- [ ] Easy solution exists, never addressed
- [ ] Character acts out of personality without development
- [ ] Danger exists but character doesn’t act like it
- [ ] Choice contradicts stated priorities
- [ ] No internal monologue explaining unusual choice
Three or more red flags = serious coherence problem
The Puppet Master Test
Ask yourself honestly:
“Am I moving this character like a chess piece to where plot needs them, or are they making choices that organically lead them there?”
Chess piece signs:
- You think “I need character at X location” then contrive reason
- Choice serves plot more than character
- You’re not sure why character would do this
- Internal logic added as afterthought
Organic choice signs:
- Character’s wants naturally lead to this action
- Choice reveals character even if plot didn’t require it
- You understand their thinking without trying
- Multiple motivations align
Frequently Asked Questions
Can characters ever make incomprehensible choices?
Only if: (a) it’s intentional characterization (character is erratic/mentally unstable, clearly established), or (b) mysterious choice is quickly explained, creating intrigue not confusion.
What if the irrational choice IS the point?
Show the internal struggle and bad reasoning. We need to understand they’re being irrational, not think the author forgot their own logic.
How much internal monologue explaining choices?
Enough that reader understands, not so much it’s tedious. Sometimes one sentence (“She knew it was stupid, but…”) is sufficient.
What about plot twists revealing different motivations?
Fine, but character’s behavior must make sense in retrospect once motivation revealed. Reread should show coherent logic.
Can I have impulsive character who doesn’t think through choices?
Yes, but impulsiveness is still a pattern. Impulsive people have logic—it’s “do the first thing I want” not “do random incomprehensible things.”

Conclusion: The Trust Equation
Here’s the fundamental truth:
Coherent choices = Reader trust Incoherent choices = Broken immersion
And once trust breaks, it’s nearly impossible to rebuild.
Your character can:
- Make terrible decisions (we’ll agonize but understand)
- Act irrationally (we’ll see the human logic)
- Choose badly (we’ll yell at the page but keep reading)
- Be flawed, biased, wrong (we’ll recognize ourselves)
Your character cannot:
- Forget their own priorities
- Ignore obvious solutions without reason
- Act out of character without development
- Make choices you can’t explain
Because readers are inside character’s world.
We know what they know. We understand what they want. We’ve built mental models of who they are.
When choices violate that model without explanation, the illusion shatters. We see the author’s hand moving the puppet, and we can’t unsee it.
But when choices flow from character—even terrible, irrational, self-destructive choices—we believe.
We may yell at them. We may want to reach into the page and shake them. But we believe, and we keep reading.
That’s the power of coherent prioritization.
Go through your manuscript right now. Find one choice that feels forced or unexplained. Ask: “Why doesn’t character choose the easier path?” If you can’t answer, you’ve found where to add the internal logic that will keep readers believing.
