Hick’s law
Hick’s Law states that the time it takes for a person to make a decision increases with the number and complexity of choices available. In UX design, too many options can overwhelm users, leading to slower decision-making and frustration
The Psychology Behind It
Named after British psychologist William Edmund Hick, this principle is based on research that shows a logarithmic relationship between the number of choices and decision time. The more options presented, the longer users take to choose, due to cognitive overload.
