ISSUE 003 / THE SPACE BETWEEN OPTIONS
More options can expand possibility while transferring the work of comparison to the chooser. What changes when you rearrange the same decisions?
An illustrative model, not a diagnosis of indecision or a shopping recommendation.
EXPERIMENT 01 / THE SORTING TABLE
A synthetic neighbourhood workshop catalogue. Every option is fictional, every rule visible, and none is declared the correct choice. Start with eight cards; then change one thing.
AN EXHIBIT, NOT A PREDICTION
The full eight-option, text-only starter catalogue appears in the static table below for readers without JavaScript.
EXPERIMENT 02 / THE GOOD-ENOUGH EXIT
Bookmark up to three fictional options, write your own stopping rule, or clear your selection. The experiment never awards a winner.

A shortlist represents attention, not a personal recommendation.
THE EVIDENCE ROOM / CLAIMS UNDER TEST
Evidence deserves more than a dramatic one-line moral. Studies disagree about whether the number of options alone undermines decisions.
Iyengar and Lepper reported experiments in which smaller assortments sometimes increased selection or purchasing. Their work challenged the assumption that adding options always improves motivation.
What it does not show: that six options are universally ideal, or that a web interface will reproduce a grocery-store result.
Original study · DOIA 2010 meta-analysis found nearly zero average effects across its sampled conditions alongside substantial variation; a 2015 analysis foregrounded context such as task difficulty, preference uncertainty and assortment complexity.
What it does not settle: the exact context in which any particular visitor will struggle or thrive.
2010 review · 2015 reviewGOV.UK's published “Check answers” pattern makes a design choice explicit: allow users to review and change information before submitting. The design illustrates reversibility, not evidence that every decision should be staged.
What remains unproven: any causal improvement caused by this museum's shortlist interaction.
Public design guidanceTHE TWELVE DECISION ROOMS
Each vignette offers two plausible stopping rules and an overlooked value. They are fictional prompts for reasoning, not claims about observed people.
ESSAY I
A wider catalogue may make room for rare needs. Someone seeking wheelchair-accessible equipment or a particular language may gain from a twenty-option set that a three-option list excludes. The difficulty is not simply the size of the shelf; it is whether the crucial difference is visible and searchable. Choice can be an expression of agency, so shrinking every catalogue may quietly erase someone.
ESSAY II
Good comparison sometimes takes time. A public decision, accessibility-sensitive purchase or multi-person commitment may deserve slower deliberation. Smoothness is not synonymous with care. A staged interface should not withhold relevant facts, manufacture urgency or force a conclusion. A useful design makes the hidden work of comparison legible rather than pretending it vanishes.
ESSAY III
Each additional attribute can demand attention, but omitting one can also hide the reason an option matters. Our two-field view suppresses context for speed; the five-field view restores it at the price of visual density. Neither creates a moral hierarchy. Ask who chooses the default columns, whose needs they reflect, and which missing attribute could reverse the shortlist.
ESSAY IV
Shortlisting is not commitment. A good-enough stopping rule says when to pause and what evidence would justify reopening the decision. Revisable choices are especially useful when information is incomplete. Some decisions cannot be easily undone; in those cases a reversible interface should not imply that real-world consequences are reversible too.

This catalogue is deterministic fiction. It cannot measure cognitive load, predict regret, diagnose fatigue, identify a best choice or generalise from a person's clicks. Our sorting rules are inspectable design decisions, not empirical psychological equations.
