INTRODUCTION

English translation pending.

CORE DEFINITION

Pixar's coincidence rule is a narrative principle stating that coincidence is acceptable when it deepens a character's problems but unacceptable when it resolves them. A character may be pushed into difficulty by accident; they may not be extracted from it by accident. The rule belongs to a set of story guidelines associated with Pixar's writing practice rather than to a single named author. Its core claim is about agency: audiences accept misfortune that arrives uninvited because it is not the character's fault, but they reject deliverance that is not earned, which is the failure mode known as deus ex machina.

SCAFFOLDING EFFECT

Reduce cognitive load

- Trouble injection: Use coincidence freely to push a character into difficulty at any point in the story. - Rescue ban: Require the character's own decisions and effort to produce every escape. - Ending audit: Check the climax for a resolution that arrives from outside the character's actions.

Anchor fast decisions

Stories work by making the audience track a character's choices and their consequences. Coincidence that creates trouble adds a problem without removing agency, so the causal chain stays intact and the audience keeps caring. Coincidence that removes trouble severs that chain: the resolution no longer follows from anything the character did, and the accumulated tension is discharged without cost. The asymmetry is therefore about agency rather than about probability.
