Laws of UX

Users spend most of their time on other sites, and they prefer your site to work the same way as all the other sites they already know.

Users spend most of their time on other sites, and they prefer your site to work the same way as all the other sites they already know. Familiarity breeds efficiency. When users encounter a new website or app, they bring with them a wealth of expectations formed from their cumulative experiences with other digital interfaces. This transfer of knowledge allows them to navigate and interact with new platforms more easily, reducing the cognitive load required to learn a new system. Benefits of leveraging familiarity: Immediate productivity Lower learning curve Reduced frustration Increased user satisfaction By aligning your design with common conventions, you enable users to focus on their objectives rather than figuring out how to use your interface. This principle, known as Jakob's Law, emphasizes the value of consistency across digital experiences.

By leveraging existing mental models, we can create superior user experiences in which the users can focus on their tasks rather than on learning new models. Mental models guide user behavior. Users approach new interfaces with preconceived notions about how things should work, based on their past experiences. These mental models serve as cognitive shortcuts, allowing users to predict how a system will behave without having to learn it from scratch. Designers can capitalize on these existing mental models by: Using familiar icons and symbols Placing common elements (like search bars) in expected locations Implementing standard interaction patterns (e.g., pull-to-refresh) By aligning your design with users' existing mental models, you reduce the learning curve and create a more intuitive, efficient user experience.

When making changes, minimize discord by empowering users to continue using a familiar version for a limited time. Gradual transitions prevent user backlash. When redesigning a popular interface, it's crucial to consider the impact on your existing user base. Abrupt changes can lead to frustration, confusion, and even user abandonment, as exemplified by the 2018 Snapchat redesign fiasco. Strategies for smooth transitions: Allow users to opt-in to new designs Provide a grace period with access to the old version Offer tutorials or guided tours of new features Collect and act on user feedback during the transition Google's approach to redesigning products like Gmail and YouTube demonstrates how gradual implementation can mitigate resistance to change and maintain user satisfaction.

A mental model is what we think we know about a system, especially about how it works. Understanding shapes interaction. Mental models are the internal representations users have about how a system works. These models are formed through past experiences, cultural influences, and interactions with similar systems. They play a crucial…
