The reason a menu with two pages sells more than one with six

A restaurant replaces its two-page menu with a six-page one. The chef is proud: every dish is now represented. Within a month the average table orders fewer items, takes longer to place the order and is more likely to choose the daily special — the one item that removes the need to compare anything at all.

What everyone sees

Diners attribute the slowness to indecision, which they treat as a personal failing rather than a structural one. The menu looks generous, and generosity from a restaurant seems like something a reasonable person should welcome. Nobody suspects the menu itself of causing the very indecision they are apologising for.

What is actually happening

Iyengar and Lepper’s jam study demonstrated that extensive choice can reduce both the willingness to choose and the satisfaction with whatever is chosen. The finding extends well beyond grocery displays: Scheibehenne, Greifeneder and Todd’s meta-analysis confirmed that the overload effect appears reliably when options are hard to compare and when the chooser has no strong prior preference, both of which describe a restaurant menu for a party of strangers.

Why it stays hidden

The overload hides because its symptom — choosing the default — looks like preference. When a table orders the daily special, the kitchen reads satisfaction; when a customer buys the middle package, the business reads a considered judgement. In both cases the chooser has retreated from comparison, but the retreat is indistinguishable from confident selection unless someone counts how long the decision took.
