Tactics for reducing options toward a decision.
- Sublists: Break too large lists into similar lists that enable choosing.
- Aggressive shortening: Remove items arbitrarily until the list is a reasonable size to assess. If an option clearly shouldn’t be removed, this approach helps identify those key options.
- Ideal criteria: Options must pass three minimum criteria, and two of three ideal/extreme criteria.
- 90% rule: For the top criterion, rank choices 0–100. Keep only 90th percentile.
