define Hicks and Fitts law

Question

Accepted Answer

Hicks and Fitts law states that the time it takes to make a decision increases with the number of choices and decreases with the familiarity of the choices.

The law is used in UX design to optimize the number of choices presented to users
It suggests that reducing the number of choices can improve decision-making time
Familiarity with the choices can also improve decision-making time
For example, a website with too many navigation options can lead to decision paralysis
Another example is a mobile app with a simple and familiar interface that allows for quick decision-making
