What is Hick’s Law?

Hick’s Law states that the time it takes to make a decision increases with the number and complexity of choices available. While the original principle is grounded in psychology (originally coined by “William Edmund Hick” and “Ray Hyman”), its application in UX design is straightforward.

When users are given too many options, they spend more time processing information, comparing alternatives, and deciding what action to take. This increases cognitive load and slows down interaction.

In digital interfaces, the effect of Hick’s Law is most noticeable in areas where users are expected to act quickly or repeatedly. Even small increases in reaction time can accumulate, creating a product experience that feels difficult to use or overwhelming.

Why Hick’s Law matters in UX design

In UX design, the goal is to present options in a way that helps users make decisions efficiently. When interfaces present too many choices without clear structure, users hesitate, make errors, or abandon tasks altogether.

This has a direct impact on key product outcomes:

• Slower onboarding and reduced activation rates
• Increased drop-off in forms and conversion flows
• Reduced engagement
• Frustration in navigation and task completion

Hick’s Law is closely linked to cognitive load. When users are required to process too many options at once, the experience becomes mentally demanding. Over time, this reduces confidence and increases the likelihood of disengagement.

How Hick’s Law applies to digital products

Hick’s Law appears across many areas of product design. It is not limited to menus or buttons. It affects any interaction where a user must choose between options.

Navigation menus

Large navigation menus with too many items can slow users down. When everything is given equal prominence, it becomes harder to scan and prioritise. Users must spend more time deciding where to go next, especially in complex platforms.

SaaS dashboards

Feature-heavy dashboards often expose a wide range of actions at once. Without clear grouping or prioritisation, users are forced to interpret and evaluate multiple options before taking action. This can make the product feel more complex than it actually is.

Forms and onboarding flows

Long forms with multiple fields, options, and decisions can create friction early in the user journey. Asking users to make too many choices too soon increases the likelihood of drop-off, particularly during onboarding.

Feature-rich interfaces

As products grow, new features are often added without restructuring existing ones. Over time, this leads to interfaces where users must navigate a large number of options to complete simple tasks.

Examples of Hick’s Law in UX design

Hick’s Law becomes easier to understand when applied to real scenarios.

A pricing page with multiple tiers and feature comparisons can create decision overload if not structured clearly. Users may struggle to identify which option is right for them, delaying conversion.

A dashboard that surfaces every available feature on the home screen can overwhelm users. Instead of guiding action, it creates friction and slows down the decision-making process.

Dropdown menus with long, ungrouped lists force users to scan and process large amounts of information before selecting an option.

Onboarding flows that ask users to configure multiple settings upfront can slow adoption. Users are required to make decisions before they understand the product’s value.

In each case, the issue is not the number of options alone, but how those options are presented.

Common mistakes when applying Hick’s Law

A common misunderstanding is that Hick’s Law means reducing the number of choices at all costs. In practice, removing options is not always the right solution.

Oversimplifying an interface can hide important functionality and make tasks harder to complete. Users may need those options, but they need them presented in a more structured way.

Another mistake is confusing fewer choices with better hierarchy. An interface can still feel overwhelming even with a small number of options if they are poorly organised.

Some products attempt to reduce complexity by hiding features behind multiple layers without clear navigation. This can make discovery more difficult and increase friction in a different way.

How to reduce decision-making friction in your product

Applying Hick’s Law in user experience design involves structuring choices so that users can make decisions quickly and confidently.

Grouping related options helps reduce the number of decisions a user has to process at once. Instead of presenting ten separate choices, they can be organised into a smaller number of categories.

Progressive disclosure allows users to see only what is necessary at each stage. Additional options are revealed as needed, rather than all at once.

Providing default selections or recommended options can guide users towards common or optimal choices, reducing the effort required to decide.

Prioritising key actions ensures that the most important options are immediately visible, while secondary actions are still accessible but less prominent.

Simplifying language and labels also plays a role. Clear, predictable wording reduces the decision time needed to interpret choices.

Applying Hick’s Law in complex systems

Hick’s Law becomes more important as products increase in complexity. In SaaS platforms and enterprise tools, users often need access to a wide range of functionality. Removing options is not realistic.

Instead, the focus shifts to structuring complexity. This might involve grouping features into logical sections, prioritising frequently used actions, and designing navigation that reflects how users think about their tasks.

In these environments, poor application of Hick’s Law can lead to interfaces that feel overwhelming and difficult to use. Strong application results in systems that feel manageable, even when they are feature-rich.

​​In our experience working on complex SaaS platforms and enterprise tools, this is where the principle has the greatest impact. The challenge is rarely a lack of functionality, but how that functionality is structured and presented. By helping UX designers reorganise choices, prioritise key actions, and introduce clearer patterns, we’ve seen products become significantly easier to navigate without removing capability.

Conclusion

By structuring options clearly, prioritising what matters, and reducing unnecessary cognitive effort, user experience designers can create interfaces that feel faster and more intuitive. This leads to better user experiences, improved engagement, and more efficient interaction across digital products.
