Top 10 Laws of UX You Should Know

Laws of UX is a collection of best practices that designers can consider when building user designs and websites for clients. Discover the Top 10 Laws of UX You Should Know to enhance user experience design and create more intuitive and engaging interfaces.

By using these laws we can make those designs that are more useful for the number of users.


• Law of proximity :

describes how the human eye perceives connections between visual elements.


• Authority bias :

Is defined as having an unreasonably high confidence in the belief that the information verified by a person with formal authority is correct, and therefore an individual is likely to be more influenced by them.

when your doctor tells you to lose weight by cutting down on carbs and starting an exercise regime, you are more likely to do it because he is your doctor and probably knows better than your mother who said the same thing last week.


• Curiosity gap

The Curiosity Gap refers to the space between what a person knows and what they want to know. It is the gap between their current knowledge and the information that they are seeking.


• Decoy effect

the decoy effect is the phenomenon whereby consumers will tend to have a specific change in preference between two options when also presented with a third option that is asymmetrically dominated. ex popcorn in the theatre


• Aesthetic Usability Effect :

Users often perceive aesthetically pleasing design compared to more usable design.

An aesthetic design creates a positive response in people’s brains and leads them to believe that the design works better.

Ex. Airbnb and OLX

People are more tolerant of minor usability issues when the design of the product or service is aesthetically pleasing.

Ex For Apple’s new launches Visually pleasing design can mask usability problems and prevent issues from being discovered during usability testing

Ex-Apple mouse charging port.

• Hick’s Law:

The time it will take to make a decision increases with the number and complexity of choice

Ex. Normal remote vs Smart remote Minimize the choice when response times are critical to increasing decision time Break complex tasks into smaller steps in order to decrease cognitive load

Ex. Amazon site while ordering. Avoid overwhelming users by highlighting user-recommended options Use progressive onboarding to minimize cognitive load for new users. Be careful not to simplify the abstraction (baseless/not a real thing/not understandable to the user)


• Goal Gradient Effect:

The tendency user to the user to complete the task, the faster they work reaching to it. Providing artificial progress towards the goal will help to ensure user are more likely to have the motivation to complete that task. Provide a clear indication of progress in order to motivate the tasks


• Miller’s Law:

The average person can only keep seven in their working memory Do not use the magical number 7 to justify unnecessary design limitations Organize content in smaller chunks to help users process, understand, and memorize easily. Remember that short-term memory capacity varies per individual based on their prior knowledge and suitable context


• Serial Position Effect:

People best remember the first and last items in a series and find it hard to remember the middle items. Placing the least important items in the middle in the list can be helpful because this item tends to be stored in working memory. Positioning the key actions on the far left navigation within the elements such as navigation can increase memorization.

Von Restorff effect:

Also known as the isolation effect is a psychological theory that predicts that people are more likely to remember things that stand out. Make info or key action visually distinctive Ex. iPhone bottom bar. We can use lines, boxes, etc to connect from one element to the next element. Through this, we will also create a visual connection. Use uniform connectedness to show contacts or to show emphasis on similar items. In a list of black and white icons a single variant and colorful icon will catch your attention. Carefully control the user with motion sensitivity when using motion to communicate contrast ex. giving options to users in surveys.


• Law of Common Region :

Elements tend to be perceived to be in a group if they are in a clearly defined boundary Common regions tend to be a clear structure and help users and structure quickly and effectively understand the relation between the element and section. Adding a border around an element or an element is an easy way to create a common region. It can also created by defining a border behind an element or group of elements.


• Law Of Proximity :

Objects that are near or proximate to each other tend to be grouped together. Proximity helps to establish our relationship with nearby objects (ex, Icons, and tabs that are together). Elements in close proximity are perceived to share similar personalities or traits (ex, the Same topic like profits and loss). Proximity helps users understand and organize information faster and more effectively.
