How it works

Carlson’s chart credits Alfred Hitchcock with describing a play as a proposition, an argument and a resolution. Nobody has traced the remark to a primary source, so the credit rests on the chart and remains unconfirmed. The idea is useful whoever said it. A story puts a question on the table and argues it until events deliver a verdict, much as a debate does, and the chart draws the parts with crossing lines to show each one handing off to the next.

The first quarter, 0–25%, belongs to the Proposition, which states the question or claim the story will test. Most of the running time goes to the Argument (25–75%). Characters fight it out in action there, and each side gains ground and loses it. From 75% to the end, the Resolution delivers the verdict through events, so the outcome itself is the answer.

On the shared timeline it matches the other three-part rows, the ones credited to Billy Wilder (The Tree) and George Lucas (Characters, Problem, Solution), with turns at 25% and 75%. The difference lies in what the labels track. Wilder’s follow a character up a burning tree and Lucas’s follow a plot problem, while this row follows an idea under test. It marks no midpoint and no lowest point, so the middle half reads as one sustained exchange with the emphasis on theme.

Courtroom dramas and debate stories fit it naturally, as does any plot hung on one clear question. It helps to phrase the proposition so it could be answered yes or no, and to state it before the 25% mark. The middle works best when each side belongs to a character with something personal at stake and the advantage swings more than once. A verdict lands hardest when an event decides it. If a character exists only to voice a position, give that person a want the verdict will reward or cost.
