The more options you show, the longer people take to choose.
Decision time grows logarithmically with the number and complexity of choices.
Find the word we show you, first among 3 options and then among 12, and compare your own times. The clock starts only when the options appear.
Show 2–3 primary options. Tuck the rest behind 'More options'.
Show a new viewer 40 genres at once and they freeze. Show three curated rows instead (“Continue watching”, “Because you liked X”, “Trending”) and they press play in seconds. Same catalogue, but each screen now asks for one small decision instead of one overwhelming one. Netflix, Spotify, and the App Store all lead with a handful of curated choices for exactly this reason.
When users are experts doing a task repeatedly, more visible options and shortcuts beat a tidy, nested menu. Hiding things just adds clicks. And when choices are genuinely distinct and scannable, a longer flat list can be faster than a shorter menu that forces people to drill in.
Hick's Law says the time to make a decision grows with the number and complexity of choices. More options mean a slower decision. It is also called the Hick-Hyman law.
Reaction time = a + b × log₂(n + 1), where n is the number of equally likely choices. Time grows with the logarithm of the number of choices, not in a straight line.
The British psychologist William Edmund Hick described it in a 1952 paper in the Quarterly Journal of Experimental Psychology. Ray Hyman extended it in 1953, which is why it is also called the Hick-Hyman law.
A streaming app that opens on three curated rows instead of forty genres, or a checkout that shows one clear payment method and keeps the rest behind More options.
No. Reduce the decisions people have to make, but do not hide what they need. Experts using a tool they know well are often faster with more controls in view, and a clearly grouped list can beat a nested menu.
An e-commerce checkout bleeds carts at the payment step — surprise costs, a forced account signup, and a wall of undivided fields. Spot what's driving people away.
