Core Idea

The Rashomon Effect — named after Akira Kurosawa's film — describes how the same event produces multiple contradictory but individually plausible accounts, each shaped by the observer's perspective, interests, and cognitive biases. There is no single "true" version; each narrator genuinely believes their account while omitting or distorting details that don't fit their frame. In business, the Rashomon Effect explains why post-mortems produce conflicting stories, why co-founders remember the early days differently, why customers and product teams describe the same experience in incompatible terms, and why acquisitions that one side considers a success are remembered as failures by the other. The effect isn't about lying — it's about the fundamental subjectivity of observation.

Section 2

How to See It

Post-Mortems
You're seeing it when each team involved in a failed project tells a coherent story that places responsibility elsewhere. Engineering blames unclear requirements; Product blames shifting engineering timelines; Sales blames both. Each account is internally consistent but mutually contradictory.
Co-founder Disputes
You're seeing it when co-founders describe the founding story differently — who had the original idea, who did the critical early work, whose contribution was decisive. Each remembers their own role with high fidelity and the other's with selective editing.
Section 3

How to Use It

When accounts diverge, resist the urge to determine which one is "right." Instead, treat each version as data about that observer's perspective and priorities. Triangulate across multiple accounts to build a more complete picture. In conflict resolution, acknowledge that both parties are describing their genuine experience — the disagreement isn't about facts but about frames.
Decision filter
"Am I hearing multiple conflicting accounts and trying to pick the 'true' one — or should I treat each account as partial truth that reveals something about the observer's perspective?"
As a founder
When team conflicts produce contradictory narratives, don't arbitrate who's right. Map each perspective, identify what each account reveals about that person's priorities and blind spots, and synthesise the overlapping elements into a more complete picture than any single narrator could provide.

Founders & Leaders

Ed CatmullCo-founder of Pixar
Catmull designed Pixar's creative process around the Rashomon Effect. The Braintrust — Pixar's feedback mechanism — worked by deliberately surfacing multiple contradictory perspectives on a film in progress. Rather than seeking a single "correct" view, the Braintrust required directors to sit with conflicting feedback and synthesise their own path forward. Catmull understood that creative problems look fundamentally different depending on your vantage point, and that the richest solutions emerge from holding multiple incompatible perspectives simultaneously rather than collapsing them into false consensus. For founders, this principle extends beyond creative work: any complex problem benefits from deliberately collecting and honouring contradictory accounts rather than prematurely converging on a single narrative.

Connected Models

Pairs-with
Narrative Fallacy
The Narrative Fallacy drives us to construct coherent stories from messy events. The Rashomon Effect shows that different narrators construct different coherent stories from the same events. Together they reveal that the stories we tell aren't discoveries of truth — they're constructions shaped by who's telling them.
Reinforces
[Blind Spot](/mental-models/blind-spot)
Each observer in a Rashomon situation has blind spots — aspects of the event they can't see from their vantage point. The Rashomon Effect is what happens when multiple blind spots produce multiple partial accounts, none of which is complete but each of which is genuinely believed.
Tension
Fundamental Attribution Error
Fundamental Attribution Error makes each narrator attribute others' actions to character while attributing their own to circumstance. In Rashomon situations, this asymmetry compounds: each narrator's account is generous to themselves and uncharitable to others, making reconciliation harder.

Summary & Further Reading

The Rashomon Effect explains how the same event produces multiple contradictory but internally coherent accounts. In business, it shows up in post-mortems, co-founder disputes, and cross-team conflicts. Rather than seeking the single "true" version, treat each perspective as partial data and synthesise across accounts for a more complete understanding.
