Occam's Razor
Among competing hypotheses, the one with the fewest assumptions should be selected. In design, simpler solutions are usually better than complex ones.
When to Use
Simplify designs
Choose the simplest solution that meets user needs. Remove unnecessary elements and complexity.
Reduce cognitive load
Simpler interfaces require less mental effort from users, making them easier to understand and use.
Focus on essentials
Prioritize core functionality and remove features or elements that don't directly support user goals.
When to Avoid
Don't oversimplify
Ensure that simplification doesn't remove necessary functionality or make the interface less useful.
Origin
Occam's Razor is a principle attributed to 14th-century philosopher William of Ockham. The principle states that when multiple explanations are available, the simplest one is usually correct. In design, this translates to preferring simpler solutions over complex ones, as they are typically easier to understand, use, and maintain.
