Hick's Law
It's easier to make decisions with fewer choices.
Why it matters
The more choices that are available to the user, the longer it will take them to reach a decision.
Conversion rates:
• People will be more likely to convert, if you have fewer options. • i.e., if you have 10 different service tiers, you might find that potential customers are being paralyzed with choice (and so choose nothing).
What to inspect
- Check whether the experience reflects this: People will be more likely to convert, if you have fewer options.
- Map each visible element to how it supports or undermines: It's easier to make decisions with fewer choices.
- Walk the primary task once with time pressure; note where attention drops.
- Ask a colleague unfamiliar with the product to paraphrase the screen in one sentence.
Common anti-patterns
- Assuming users consciously notice every place where "It's easier to make decisions with fewer choices" could apply.
- Dense copy and parallel actions that increase mental effort unrelated to the user’s goal.
- Ignoring downstream effects on conversion rates when shipping this pattern.
