Understanding these core UX laws can significantly transform your approach and elevate the user experience. Here’s a detailed breakdown of the “Laws of UX” to guide your next SaaS product.
1️⃣ Hick’s Law
💡 More choices = longer decision time. When users are presented with too many options, they can become paralyzed.
To combat this, simplify the choices available to users.
By narrowing down options and presenting them clearly, you can help users make quicker, more confident decisions, ultimately enhancing their experience and satisfaction.
2️⃣ Fitt’s Law
🖱️ Larger, closer targets are more accessible to reach. This law emphasizes the importance of size and proximity in design.
Key interactive elements, such as buttons and links, should be large enough to be easily clickable and positioned within easy reach of the user’s cursor or finger.
By making these elements prominent and accessible, you enhance usability and reduce frustration, leading to a smoother interaction.

3️⃣ Jakob’s Law
🔄 Users expect familiar patterns. Users come to your site or app with preconceived notions based on their experiences with other platforms.
You can meet user expectations and create a more intuitive experience by leveraging commonly used design patterns and conventions.
Familiar layouts and navigation structures help users feel comfortable and confident, reducing the learning curve and improving overall usability.
4️⃣ Miller’s Law
🔢 Users can remember about seven items. Cognitive load is a critical factor in user experience.
Since users typically hold only about seven pieces of information in their working memory, organizing content into smaller, digestible groups is essential.
This can be achieved through lists, categories, or visual hierarchies, making it easier for users to recall information and navigate your design effectively.
5️⃣ Tesler’s Law
🛠️ Simplify your design but maintain necessary complexity where it adds value. While simplicity is critical in design, it’s essential to recognize that some complexity is required to provide value.
Focus on streamlining the user experience by eliminating unnecessary features and distractions, but ensure that essential functionalities are preserved.
This balance allows users to engage with your design without feeling overwhelmed.
6️⃣ Law of Proximity
📏 Items placed close together are perceived as related. The spatial arrangement of elements is crucial in how users interpret information.
By grouping similar items, you can create a visual relationship that guides users intuitively.
This principle helps users understand connections between elements, making navigation and comprehension more straightforward.
7️⃣ Doherty Threshold
⚡ Users are more engaged when response time is under 400ms. Speed is a critical factor in user engagement. Research shows that users are more likely to stay engaged when they receive feedback or responses within 400 milliseconds.
To maintain user interest and immersion, ensure your design is optimized for quick load times and responsive interactions, minimizing any delays that could disrupt the user experience.
8️⃣ Aesthetic-Usability Effect
🎨 Attractive designs feel more straightforward to use. The visual appeal of a design can significantly influence user perception.
Users often associate aesthetically pleasing designs with better functionality, even if their usability is the same as that of a less attractive counterpart.
Investing in a visually appealing design can enhance user satisfaction and enjoyment, making the overall experience more positive.
9️⃣ Law of Similarity
🔗 Elements that look similar are perceived as related. This principle states that users tend to group items with visual characteristics like color, shape, or size.
Using consistent design elements across your interface creates a cohesive experience that helps users understand relationships between different components.
This can improve navigation and make it easier for users to find what they want.
🔟 Postel’s Law (Robustness Principle)
🔄 Be conservative in what you send and liberal in what you accept. This principle emphasizes the importance of designing systems that can handle various user inputs gracefully.
While you should strive for clarity and precision in your design, it’s equally essential to accommodate user errors and unexpected behaviors.
By allowing for flexibility and providing helpful feedback, you can create a more forgiving user experience that encourages exploration and reduces frustration.
1️⃣1️⃣ Zeigarnik Effect
🧠 People remember uncompleted or interrupted tasks better than completed ones. This psychological phenomenon suggests that users are more likely to recall functions they have started but have not finished.
In UI/UX design, you can leverage this effect by providing users with reminders or visual cues about incomplete actions, such as items left in a shopping cart or forms that need to be completed. This can help keep users engaged and encourage them to return to complete their tasks.
1️⃣2️⃣ Pareto Principle (80/20 Rule)
📊 Roughly 80% of outcomes come from 20% of causes. In UX, this translates to recognizing that a small portion of your product’s features or content will drive most user engagement and satisfaction.
Focus on perfecting the most critical 20% of features that add the highest value. For example, spending more time optimizing messaging features over less-used elements in a messaging app yields the highest satisfaction.
How do AI models utilize these UX laws when interacting with humans?
AI models leverage UX laws to enhance user interactions by creating more intuitive and practical experiences. Here are some ways they do this:
- Predictive Behavior: AI can analyze user data to anticipate needs and preferences, aligning with the Law of Proximity, which suggests that users expect related items to be close together. AI models can streamline decision-making and improve user satisfaction by presenting relevant information or options based on user behavior.
- Adaptive Interfaces: AI models can adjust their interfaces to group similar functions or features using the Law of Similarity. This helps users quickly identify related actions, making the interaction more intuitive and reducing cognitive load.
- Error Handling: By Postel’s Law, AI systems are designed to handle a variety of user inputs gracefully. They can provide helpful suggestions or corrections when users make mistakes, ensuring a smoother experience and encouraging users to continue engaging with the system.
- Task Reminders: By applying the Zeigarnik Effect, AI models can remind users of incomplete tasks or actions. For instance, an AI assistant might notify users about items left in a cart or unfinished forms, prompting them to complete their functions and enhancing user engagement.
- Data-Driven Improvements: AI models utilize the A/B Testing Law by continuously analyzing user interactions and preferences. They can test different design variations and learn from user feedback, allowing for iterative improvements that lead to a more user-friendly experience.
By integrating these UX laws into their design and functionality, AI models can create more effective, user-centered interactions that enhance overall satisfaction and usability.
