The connective logic that links every scene to the next through consequence rather than coincidence.
Applies to: All story types
Definition
The principle that every event in the story must flow logically from the previous event. In TSM, cause-and-effect is enforced through connective logic — every scene transition should be justified by words like because, but, thus, therefore, so, naturally. The enemy of cause-and-effect is "and then" thinking: a series of events that follow each other in time but do not cause each other.
Why This Term Matters
Cause-and-effect is what separates escalation from accumulation. A story built on cause-and-effect feels inevitable — every development follows from the last, and the audience can feel the story tightening around the Protagonist. A story built on "and then" feels arbitrary — things happen, but they could have happened in any order, and removing any one of them would not change what comes after.
Cause-and-effect is also the mechanism that keeps the Habit at the centre of the plot. If every scene is a consequence of the Protagonist's decisions (which are themselves consequences of the Habit), then the Habit is the cause of everything. The story becomes a demonstration of what the Habit costs — which is the only way THE Theme can be revealed through action rather than stated through dialogue.
The Test
Read your sequence using only the connectives. Does it work?
- Scene 1 happens. Therefore Scene 2 happens. But Scene 3 happens. Therefore Scene 4 happens.
If you have to use "and then" anywhere, that is the seam where the cause-and-effect has broken down. Ask: what decision or consequence should be driving this transition?
In a Kind Comedy — Examples
Ratatouille (Sequence B): Linguini is ordered to throw away the soup. But he adds to it instead. Therefore the soup is served accidentally. But the soup is a sensation. Therefore Skinner is trapped — he cannot punish Linguini without explaining why the soup should not have been served. Therefore Linguini is kept on. But Skinner suspects something. This is pure cause-and-effect: no "and then" in sight.
In Bruges (Sequence A): Ray and Ken arrive in Bruges under Harry's orders. Therefore they wait. But Ray is miserable — the beauty of the city means nothing to him through his guilt. Therefore Ken tries to engage him with sightseeing. But Ray cannot be engaged. Therefore the tension between what Ken wants (to follow Harry's orders peacefully) and what Ray needs (absolution) is established before the story's real conflict begins.
