Inciting incident

The inciting incident is the event that disrupts a character's ordinary situation and sets the story's central problem in motion — the point at which going back to normal stops being an option.

A story only begins once there is a problem. A town going about its daily business is not a story; a town cleaning up after a landslide is the start of one, because something is now wrong that somebody will have to deal with.

The test is not size but consequence. An inciting incident does not need an explosion — it needs to make the character's ordinary arrangements unworkable, so that a want becomes urgent and the throughline starts. The letter arrives, the diagnosis lands, the partner does not come home. What matters is that afterwards, doing nothing has a cost.

It is one of the four parts of a logline, alongside the need, the desire and the antagonist, which is a fair indication of how much of a story it determines.

Two common faults, both cheap to fix in revision. The first is an inciting incident that arrives on page sixty, with everything before it serving as introduction — early drafts almost always delay the big turns, and almost always survive having them moved up. The second is an incident that happens to the character with no choice attached. The disturbance is external; the response has to be a decision, or the book opens with a passive protagonist.
