For choices you are about to offer someone
Fewer DoorsOffer fewer choices, and suggest one.
Every extra option makes choosing slower. List what you are about to offer, say how they will choose, and open only the few doors that fit - the rest stay on request, and a lamp marks the one you would pick. One run judges which to keep and why, or groups everything under a few headings when it all must stay.
1 The options free
Or drop a .txt (a first line starting "For:" becomes the goal) or a .json file here.
2 The street free
Click a door (or focus it and press Enter) to open or close it. The free trim keeps must-offer options first, then your list's order. Choice load is Hick's law as an illustration - log2 of the options plus one - not a measurement of anyone.
3 The short list metered
One run keeps the options that best fit who is choosing, with a reason each, suggests one, folds near-repeats into one wording - or groups everything under a few headings when it all must stay. The page re-checks the reply.

How it works
Hick's law: the time it takes to choose grows with the number of options in front of you - roughly with log2 of the options plus one. Going from nine options to three takes the load from about 3.3 bits to 2. The effect is strongest when the options are equally likely and unfamiliar; a regular who always orders the same thing barely notices.
How many at once depends on how the choice is made: said out loud, three is plenty because the chooser has to hold them in mind; at a glance on a sign or screen, four; read at leisure on a menu or a form, seven. Options you close are not gone - they are "on request" if anyone asks.
When everything must stay on offer - a menu, a price list - the run groups the options under a few short headings instead, so the first choice is between headings, not between every item. A suggested pick gives anyone stuck a way out.
