History

Hick’s law, or the Hick–Hyman Law, is named after British and American psychologists William Edmund Hick and Ray Human. In 1952, they decided to study the dependence between the number of stimuli  and an individual’s reaction time to any of them. As a result of the study, Hick and Hyman found that, the more stimuli to choose from, the longer it takes the person to decide on which one to interact with.

Tips‍

#1

Reduce the number of choices when response time is critical to increase decision time. For example, this is important for control system environments.

#2

Break down complex and long processes into smaller steps to reduce cognitive load. For example, you can divide the user registration process into several screens. It will make the interface more user friendly.

#3

Keep a balance between reducing complexity and oversimplifying. Breaking down the choices for a series of lots of small chunks can make the user to leave before reaching the goal.
