Reduce choices for routine/low-stakes/high-frequency decisions — maintain full optionality only for novel/high-stakes/infrequent ones

Why This Is a Rule

Choice reduction is powerful for the right decisions and harmful for the wrong ones. This rule provides the classification that determines where to apply it. Four factors determine whether reduction or full optionality is appropriate: Routine vs. novel (routine decisions benefit from reduction; novel ones need exploration). Low vs. high stakes (low-stakes decisions don't justify comparison effort; high-stakes ones do). High vs. low frequency (frequent decisions accumulate decision-fatigue cost; infrequent ones don't). Hard vs. easy comparison (options that are hard to compare produce overload more quickly; options with clear evaluation criteria can handle larger sets).

When all four factors point toward reduction (routine + low-stakes + high-frequency + hard to compare) → reduce aggressively. When all four point toward optionality (novel + high-stakes + infrequent + clear criteria) → maintain full option set. Mixed cases require judgment, but the principle is: preserve cognitive resources by reducing where reduction is safe (most daily decisions) so full optionality remains available where it's necessary (consequential decisions).

When This Fires

• When designing your personal choice architecture across life domains
• When deciding whether a specific decision domain should be simplified or left open
• When blanket simplification has been applied to decisions that deserve full exploration
• Complements Limit recurring low-stakes decisions to 3-7 options — this range matches working memory for effortless comparison (3-7 option range) with the classification of which decisions warrant reduction

Common Failure Mode

Uniform approach: either reducing everything (missing important novel options) or reducing nothing (drowning in decision fatigue from trivial choices). The classification produces a mixed portfolio: reduced options for daily routine, full options for consequential choices.

The Protocol

(1) For each recurring decision domain, score four factors: Routine (1-5: 1=completely novel, 5=daily recurrence). Stakes (1-5: 1=trivial, 5=life-altering). Frequency (1-5: 1=once/year, 5=multiple times/day). Comparison difficulty (1-5: 1=clear criteria, 5=options are essentially indistinguishable). (2) High scores on routine + low stakes + high frequency + hard comparison → reduce options (Limit recurring low-stakes decisions to 3-7 options — this range matches working memory for effortless comparison). (3) High scores on novel + high stakes + low frequency + easy comparison → maintain full optionality. (4) Apply reductions gradually: start with the most obviously reducible domains (daily meals, wardrobe, break locations) before touching anything borderline.
