Defer judgment during generation

Generate ideas with no criticism, then evaluate in a separate pass.

Why it works

Evaluation and generation compete: judging an idea the moment it appears activates self-censorship that suppresses the next, riskier idea before it forms. Separating the two phases protects the fragile early ideas long enough to develop, and the wild ones often seed the best final answer. The split is what keeps the pipeline open.

How to do it

1. Declare a generation phase where no idea may be criticized, including by you.
2. Write everything, especially the “bad” ideas — they’re raw material, not commitments.
3. Only after generating, switch deliberately into an evaluation phase.

Evidence

The separate-generation-and-evaluation principle is well supported in creativity research and is the most reliable element of brainstorming guidance; deferring judgment increases the quantity of ideas produced. (observational)

It increases quantity reliably; quantity correlates with eventually finding good ideas, but doesn’t guarantee quality on its own — the evaluation pass still matters.

Common mistake

Sneaking evaluation into generation (“that won’t work”), which shuts down the flow the entire method depends on.
