Key Principle
Every event in a story must connect to the next through "therefore" or "but" — never "and then." This test operates on two simultaneous levels. Internal: "What would my protagonist's belief/past experience cause him to do?" External: "How will the world react to what my protagonist does?" The logic is biological: "fMRI research shows that when we engage with a story, our brain literally synchronizes with the speaker's brain patterns" — Lisa Cron, Chapter 7. Cause-and-effect logic is what enables this neural coupling. Without it, synchronization breaks and the reader disengages.
Between the origin scene and page one, the misbelief must grow through three turning-point backstory scenes — moments where the protagonist stood at a crossroads and the misbelief tipped the scales. Each decision changes her external life, raises the stakes, sharpens desire, and strengthens the misbelief. The protagonist's accumulated history becomes the novel's force of opposition.
The therefore/but test comes from Trey Parker's insight (cited in Chapter 7): if you can connect your scenes only with "and then," you have a list of events, not a story. If each scene forces a "therefore" or "but," you have causal momentum.
Why This Matters
Without cause-and-effect chains, the protagonist arrives at page one with amnesia — no accumulated experience, no specific memories to draw on, no internal logic for present decisions. A thirteen-year-old who decides "girls are bad news" would not hold that belief unchanged until forty-two; "love, pain, and the whole damn thing would have ambushed him at every turn, continually testing, refining, and strengthening his resolve" — Lisa Cron, Chapter 7.
If the writer leaps from origin scene to page one without tracing the misbelief's growth through turning points, the protagonist's present behavior has no foundation. The story feels arbitrary because it is arbitrary. The reader cannot invest in a character whose decisions have no discernible history behind them.
The therefore/but test also serves as a diagnostic: when a scene resists connection to its neighbors through "therefore" or "but," that scene likely belongs in the Random Scene Cards folder, not the blueprint.
Good Examples
The three turning-point backstory scenes must each meet four criteria: (1) the protagonist stood at a crossroads and had to choose, (2) the decision had escalating, ongoing ramifications, (3) the misbelief tipped the scales, and (4) the protagonist had a real shot at getting what she wanted but the misbelief prevented it. "Many of these scenes will appear in snippets and as flashbacks in the novel itself" — Lisa Cron, Chapter 7.
Keith Oatley's research describes fiction as "a simulation that runs on the software of our minds... requiring us to weigh up myriad interacting instances of cause and effect" — cited in Chapter 7. This is why therefore/but logic is not a stylistic choice but a cognitive requirement.
The misbelief is described as "buried like a seed — one that immediately took root and has been snaking through [the protagonist's] life ever since, actively guiding his action" — Lisa Cron, Chapter 7. The turning-point scenes reveal how that seed grew: desire shape-shifts, the protagonist may convince himself he does not want the thing at all, but the conflict remains alive and intensifying beneath the surface.
Counterpoints
- "And then" plotting: Stringing events together without causal links produces episodic narrative. Readers may enjoy individual scenes but feel no compulsion to continue because nothing is at stake cumulatively.
- Skipping from origin to page one: The protagonist enters the story as a blank slate with a label ("abandonment issues") rather than a lived history. Behavior becomes generic rather than specific.
- Making backstory static: If the misbelief does not evolve through turning points, it remains a flat thesis statement instead of a living, strengthening force. "You can't simply decide something is true, and bingo, it is" — Lisa Cron, Chapter 7.

Rules of Thumb
- Connect every scene with "therefore" or "but" — if you can only say "and then," the scene has no causal link
- Write three turning-point backstory scenes between origin and page one, each meeting all four selection criteria
- Test every event on both tracks simultaneously: what would the protagonist's belief cause her to do, and how would the world respond?
- Each turning point must escalate: higher stakes, sharper desire, stronger misbelief
- Past decisions create present vulnerabilities — mine the protagonist's turning-point history for the novel's force of opposition
- The misbelief must evolve over time, not remain frozen at its origin-scene formulation
