Cultivate the slow hunch: let ideas develop over months, not hours

Resist the urge to act on a half-formed idea; keep it alive in a notebook until adjacent pieces arrive to complete it.

Why it works

Johnson argues that most breakthrough ideas are slow hunches — incomplete intuitions that require months or years of adjacent development before they become actionable. Premature action on a partial idea collapses it to what is already known, preventing the accretion of adjacent concepts that would have made it genuinely new. Keeping a slow hunch in a notebook or running document allows it to absorb new connections without being committed to prematurely.

How to do it

1. When a partial idea or intuition arrives, write it in a dedicated "hunches" notebook without trying to complete it.
2. Return to it weekly; add new fragments, connections, or contradictions without forcing them into a conclusion.
3. After 30 to 90 days, review the entry: has adjacent information arrived that completes or extends it?
4. Act only when the hunch has absorbed enough adjacent material to be genuinely executable.

Evidence

Incubation research consistently shows that setting aside a problem and returning to it later improves solution quality, likely through spreading activation during the rest period. The "slow hunch" is a long-form application of this mechanism. (observational)

Incubation research typically uses hours-long intervals; the months-long slow-hunch timescale is Johnson’s practitioner observation, and the specific mechanism over that duration is less directly studied.

Common mistake

Either abandoning the hunch because it is incomplete, or forcing it into a project before enough adjacent material has arrived — the discipline is neither discarding nor premature execution.
