Generate with constraint prompts

Use forced rules — “no X”, “must include Y”, “as if for Z” — to redirect idea generation.

Why it works

A constraint prompt is a steering input: it narrows the search to a region you wouldn’t have entered by default, so the ideas it yields are different from your habitual ones. Rotating through several distinct prompts samples several distant regions, widening overall coverage of the idea space. Each prompt is a different doorway into territory the default would skip.

How to do it

1. Write 4–6 constraint prompts (“remove the main feature”, “design it for a child”, “half the budget”).
2. Generate ideas under each prompt separately, without judging across them.
3. Pool the results and only then evaluate; the value is in the spread of doorways.

Evidence

Consistent with the broader constraint literature and with structured ideation practice: directed prompts move generation into less-accessible regions of the idea space. Mechanistic application of the constraint finding. (mechanistic)

The specific prompt sets are practitioner technique; the supporting evidence is the general finding that constraints redirect search, not these prompts in particular.

Common mistake

Reusing the same one or two prompts every time, which re-enters the same region and stops producing variety. The point is rotating distinct doorways.
