Defer judgment during generation
Generate ideas with no criticism, then evaluate in a separate pass.
Key takeaways
- What it is: 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.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Sneaking evaluation into generation (“that won’t work”), which shuts down the flow the entire method depends on.
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
- 1Declare a generation phase where no idea may be criticized, including by you.
- 2Write everything, especially the “bad” ideas — they’re raw material, not commitments.
- 3Only after generating, switch deliberately into an evaluation phase.
What the evidence says
ObservationalThe 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.
Honest caveat: 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.
IX Coach enforces the two phases for you — keeping you in pure generation and flagging when you start judging too early, then switching you cleanly into evaluation.
