Separate divergence from convergence sessions
Keep idea generation and idea selection in separate sittings — never mix the modes.
Key takeaways
- What it is: Keep idea generation and idea selection in separate sittings — never mix the modes.
- Why it works: Evaluation and generation use different cognitive states: generation benefits from loose, associative thinking; evaluation requires critical, comparative thinking. Running them simultaneously means neither runs well — the evaluative voice prunes ideas before they fully form, while premature commitment prevents the generative pass from opening up.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Treating the generate session as "done" too quickly — a truly open diverge phase feels uncomfortably unresolved. Stopping when it feels messy is stopping too early.
Why it works
Evaluation and generation use different cognitive states: generation benefits from loose, associative thinking; evaluation requires critical, comparative thinking. Running them simultaneously means neither runs well — the evaluative voice prunes ideas before they fully form, while premature commitment prevents the generative pass from opening up.
How to do it
- 1Schedule two separate sessions: one explicitly labeled "generate only," one labeled "select only."
- 2In the generate session, write down everything without rating or crossing anything out.
- 3In the select session, work from the list — don’t add new options, just choose.
What the evidence says
MechanisticThe principle of separating divergent and convergent phases is consistent with dual-process accounts of cognition and with the core finding that mixed evaluation-and-generation hurts both quantity and quality of ideas.
Honest caveat: The specific two-session format is a practitioner heuristic; the underlying cognitive case for mode separation is theoretical but well grounded.
Common mistake
Treating the generate session as "done" too quickly — a truly open diverge phase feels uncomfortably unresolved. Stopping when it feels messy is stopping too early.
IX Coach explicitly names which mode you’re in and won’t let you evaluate until the generation phase is declared complete — structuring the session boundary for you.
