Laws of UX
Hick's Law
Decision time increases with the number and complexity of choices. Reduce options, use progressive disclosure, break complex tasks into steps. Directly supports cognitive accessibility.
In plain terms
The more choices you offer, the longer people take to decide. Fewer, clearer options help everyone act faster.
Why this matters
Every extra option adds decision time and mental load. Pile on choices and you lose people — especially those with cognitive disabilities, who are first to feel overwhelmed and abandon the task.
