Hick's Law

01 / UNDERSTAND

The idea

As the number of possible responses grows, choosing can take longer. In interfaces, the usefulness of the choices, their organisation and the reader’s familiarity matter as much as the count. A small menu of confusing labels can be harder than a larger, well-organised one.

More alternatives can increase the time required to choose. In practice, familiar labels, grouping and the need to compare consequences also matter. A catalogue of many items can be useful if it supports search and filtering. Focus on reducing the difficulty of a decision rather than applying an arbitrary limit to every menu.

02 / RECOGNISE

See it in real products.

Examples of how the principle can appear in an interface.

SwiggyEXAMPLE 01

Curate a large catalogue into a smaller decision

Swiggy’s dish collections offer a focused set of meal ideas. The user can begin with a relevant shortlist rather than comparing the full catalogue.

HeadwayEXAMPLE 02

Give an undecided user one option to evaluate

Headway’s random-pick control replaces an open-ended catalogue decision with a concrete suggestion. The reader can accept it or keep exploring.

NetflixEXAMPLE 03

Plenty to watch, too much to choose

Netflix recommendations and smaller collections give people a manageable starting point within a large catalogue. The design question is whether the grouping makes the choice easier to understand.
