Hick's Law

The time it takes to make a decision increases with the number and complexity of choices.

Why it matters

Streaming services learned this the hard way: showing 15 subscription tiers doesn't help users choose. It causes them to leave. Netflix defaults to one recommended plan for a reason.

Key Principles

1Minimize the number of choices presented at any given time.
2Break complex tasks into smaller, sequential steps.
3Highlight recommended options to reduce decision time.
4Use progressive disclosure to manage complexity.
