10 Principles and Laws of UX Design Every Designer Should Know
Good UX design is an essential part of any successful product. To ensure that the user experience is satisfactory and enjoyable, it is important for designers to be aware of the principles and laws of UX design. In this blog post, we will provide an overview of the 10 most important principles and laws of UX design, and explain why every designer should know them. Understanding these principles and laws will help you create effective designs that keep users engaged and satisfied. So if you’re a designer looking to stay on top of the latest trends, read on to learn more about the principles and laws of UX design.
1) Jakob's Law
Jakob's Law is one of the key principles of UX design. It states that when designing a website, people expect it to behave like other sites they have used. In other words, users expect that elements on the page, such as navigation and other common UI elements, will be in the same place and function the same way on all websites.
Jakob's Law serves as an important reminder for designers that consistency is key. If users can’t quickly find what they are looking for because elements are scattered around the page, their experience will suffer and they may even leave the site. To prevent this from happening, designers should strive to create an intuitive user interface where common elements are grouped together in familiar locations. This will give users a sense of familiarity and make it easier for them to navigate and find what they are looking for.
2) Hick's Law
Hick’s Law, also known as the Hick–Hyman Law, states that the time it takes to make a decision increases with the number of choices available. This law was formulated by British psychologist William Edmund Hick in 1952 and was later refined by American psychologist Ray Hyman.
The basic premise of Hick's Law is that the more choices a person has, the longer it will take them to make a decision. In other words, people tend to be overwhelmed by too many options, which can lead to indecision. A classic example of Hick's Law is shopping at a supermarket: if you have a few items on your shopping list, it may take you only a few minutes to locate them; however, if you have many items on your list, it could take you much longer.
The practical implications of Hick’s Law can be seen in design, where it is used to limit the number of options available to a user. For instance, when designing a website, designers should strive to keep menu items and buttons to a minimum so as not to overwhelm the user. Additionally, using Hick's Law to simplify choices can help users quickly find what they are looking for, thus creating a better overall user experience.
3) Fitts's Law
Fitts's law is a model of human movement in interactive systems which states that the time required to rapidly move to a target area is a function of the distance to the target and the size of the target. It is one of the most widely used and accepted principles of human-computer interaction and is often used in the design of user interfaces.
The law was first proposed by Paul Fitts in 1954 and was later refined by his colleague Steven Poulton. Fitts’s law states that the time it takes to move a hand or pointer to a target area is proportional to the logarithm of the ratio between the distance to the target and the size of the target. In other words, the bigger the target and/or the shorter the distance, the faster you can reach it.
This principle has been successfully used in many fields such as video game design, industrial control systems, touchscreens, and virtual reality applications.
In designing user interfaces, Fitts's law can be used to create more effective and efficient interactions. By making targets bigger, reducing distances between targets, and making targets easier to reach, user experience can be improved significantly. Additionally, creating larger targets for important functions may encourage users to make use of those features more often.
Fitts’s law is an important principle for every designer to consider when developing user interfaces. By applying Fitts's law in their designs, designers can help create better user experiences.
4) Miller's Law
Miller's Law is a cognitive psychology principle developed by George A. Miller in 1956. It states that the average person can only remember about seven items at once. This means that for user experience design, it's important to limit the number of items on a page or screen to seven or fewer. For example, when creating a navigation bar, it should have no more than seven links. Miller's Law is also relevant when designing forms and creating layouts – too many elements can be confusing and overwhelming for users. Additionally, when designing text-heavy pages, it is important to break down long chunks of information into shorter paragraphs or lists so as not to exceed the user’s capacity to absorb the content. Ultimately, Miller's Law is a great guideline to keep in mind when designing user interfaces and experiences.
5) Mere-Exposure Effect
The mere-exposure effect is a psychological phenomenon where people tend to prefer things just because they are familiar with them. This phenomenon was first proposed by Robert Zajonc in 1968, who suggested that the more times we are exposed to something, the more we like it. The effect has been found in many different contexts, from advertising to politics.
For UX designers, the mere-exposure effect can be used to their advantage. Designers can increase the likelihood of users engaging with their products by making them more familiar. This can be done through the use of familiar images, sounds, and colors, or by using elements of existing popular designs. By making a design more familiar, it can become easier for users to understand how to interact with it and help them feel more comfortable using it.
6) sunk cost fallacy
The sunk cost fallacy is a cognitive bias that occurs when individuals continue to invest in an endeavor despite the fact that they have already incurred costs or losses and their prospects of recouping those losses are slim. It is a phenomenon where people tend to invest more resources into a project, even if it is no longer cost-effective, simply because of the time, effort, and money already invested in it.
The sunk cost fallacy can be dangerous as it can lead to people investing more money and time into an endeavor that may never be successful. It is important for designers to recognize this fallacy and to understand that, no matter how much time or money has been invested into a project, it is best to move on if it appears to be unprofitable. Designers should always weigh the benefits of investing further resources versus moving onto a different endeavor.
7) Endowment Effect
The Endowment Effect is the psychological phenomenon in which people are more likely to value something they already own than if they didn't own it. This effect can lead people to be reluctant to part with an item even when offered a better alternative. This effect can be seen in the context of design and UX when a user may be unwilling to switch from one platform to another, or try out new features, because they have become accustomed to a certain way of doing things. This effect can also explain why people have a difficult time switching from their existing technology to something new, even when the new technology offers more features or benefits. The Endowment Effect helps explain why people may be so loyal to one brand, product, or platform that they would choose it over alternatives that may be objectively better for them. Designers should be aware of this phenomenon and ensure that any new changes or features are introduced in a way that does not alienate existing users who are accustomed to the status quo.
8) Zeigarnik Effect
The Zeigarnik Effect is an important principle in user experience design that states that humans are more likely to remember incomplete tasks rather than complete tasks. This effect was first discovered by Russian psychologist Bluma Zeigarnik in the 1920s. The main idea behind the Zeigarnik Effect is that when a task is left unfinished, it will remain in our minds as an open loop, creating a feeling of discomfort and prompting us to take action in order to finish it.
In UX design, the Zeigarnik Effect can be used to make a product or service more engaging and memorable. For example, a game or app can use the Zeigarnik Effect to keep users hooked by leaving tasks unfinished. By presenting users with a challenge that they need to complete in order to move on, designers can create an engaging experience that encourages them to come back for more.
The Zeigarnik Effect also plays an important role in user retention and loyalty. It can be used to encourage users to revisit a product or service, as well as to make users feel attached to it. For instance, a website may send out automated emails reminding users to complete unfinished tasks or showing progress made towards completion. This type of interaction helps keep users engaged and more likely to come back for more.
Overall, the Zeigarnik Effect is an important principle of user experience design that helps designers create more engaging and memorable products and services. By understanding how this effect works, designers can leverage it to create experiences that keep users coming back for more.
9) Framing Effect
The framing effect is a cognitive bias in which people are influenced by the way a problem or decision is presented to them. This is often used in marketing, where a product is framed to highlight certain aspects of the product to make it more attractive or desirable. For example, an item can be framed as a “luxury” item or a “value” item to influence people's perception and behavior.
In UX design, the framing effect plays a role in how users interact with products and services. For example, when users are presented with a task, they may perceive it differently depending on the way it is framed. If a task is framed as complex or difficult, then users may be less likely to complete it or have a negative experience. On the other hand, if a task is framed as easy and straightforward, then users may be more likely to attempt it and have a positive experience.
The framing effect can also be used to influence user behavior. For example, a UX designer can use frames to emphasize the value of completing a task or buying a product. The designer can present information in a way that emphasizes the potential rewards of completing the task or the benefits of buying the product. In this way, the designer can motivate users to take the desired action.
Overall, the framing effect is an important part of UX design. By understanding how users perceive and respond to different frames, designers can create better experiences and more successful products.
10) Status Quo Bias
Status quo bias is a type of cognitive bias that causes people to prefer things to remain the same and avoid change. This type of bias can lead to decisions that are based on a person’s existing beliefs rather than considering new, possibly better, alternatives. Status quo bias is related to loss aversion – the idea that people are more likely to choose what they already have rather than risk taking something different.
Status quo bias affects UX design in many ways, from decisions regarding the design of interfaces to how user feedback is handled. For example, if a designer creates an interface with a particular layout that works for most users, it can be difficult for them to make changes even if there are user requests for them. The designer may be reluctant to deviate from the original design and as a result miss out on opportunities to improve the user experience.
In addition, designers should be aware of how they react to feedback from users. If they take a status quo approach to feedback, they may not consider different options that might make the user experience better. A better approach is to take all feedback into account but also investigate further to decide what changes should be made.
Ultimately, status quo bias can have a detrimental effect on UX design and it is important for designers to be mindful of it when making decisions. By taking an open-minded approach and considering different options, designers can create an optimal user experience that is both effective and enjoyable for all users.
