Pre-commit to a hard option limit

Decide in advance how many options you will consider — then stick to that number.

Why it works

Cognitive load grows roughly proportionally with the number of live comparisons. Limiting to three or four options constrains the comparison set to what working memory can hold simultaneously, preventing the cascading interference that makes large sets feel paralyzing. The pre-commitment does the work of willpower by making the rule structural.

How to do it

1. State your limit aloud or in writing before the search ("I will consider at most four apartments").
2. Rank the first options as you encounter them; once the limit is reached, only a new option that strictly dominates the current best earns entry.
3. Treat the limit as a constraint, not a guideline — exiting it reopens the exhausting search.

Evidence

Iyengar & Lepper’s jam study found dramatically lower purchase rates when 24 jams were offered versus 6, providing direct experimental evidence that smaller sets improve decision follow-through. (rct)

The jam study has faced replication challenges in some contexts; the size of the effect depends on domain, expertise, and whether the chooser has clear preferences. The directional finding — that reducing options helps — is the reliable takeaway.

Common mistake

Treating the limit as "approximately four" and letting it drift upward as new options appear attractive, which defeats the purpose.
