What you'll learn
Laws are shortcuts, not rules
The laws of UX summarise how people perceive and decide. Use them to explain and predict behaviour, then validate with real users.
Reduce choices, chunk information
Hick’s Law and Miller’s Law both argue for fewer options and grouped content.
Respect expectations
Jakob’s Law reminds us people spend most of their time on other sites, so familiar patterns win.
UX Laws Quiz FAQ
What is Hick's Law?
Hick’s Law says decision time grows with the number and complexity of choices. Fewer, clearer options make decisions faster.
What is Jakob's Law?
Jakob’s Law says users prefer your site to work like the other sites they already know, so follow familiar conventions.
What is the Doherty Threshold?
Productivity soars when a system responds in under 400 ms, so users and the interface stay in flow.
