Hick's Law

Interaction Design

A principle stating that the time it takes to make a decision increases with the number and complexity of choices available. UX designers apply Hick's Law by limiting menu options, using progressive disclosure, and removing unnecessary choices from key decision points.

Common contexts

Use when

When users are stalling at a decision point and analytics show drop-off — cut the options visible at once, hide secondary choices behind a 'more' control or progressive disclosure.

Avoid when

Don't apply it by hiding options that power users need fast access to — reducing choice at the wrong level forces more clicks and makes experienced users feel patronized.

The real cost of violating Hick's Law isn't slow decisions — it's users who stop trusting the interface and start second-guessing every choice they make.
