Every UX designer will get the benefit of the following 10 basic rules to create a better user experience for users.

1. The Aesthetic-Usability Effect

Users often perceive aesthetically pleasing design as design that’s more usable. Though, a nice-looking UI can make users more forgiving of minor usability issues, but not of larger ones.

2. The rule of the first impression

When users have a positive emotional response to the design, they tend to spend more time using the product.

3. Short attention spans

A 2015 Microsoft study found that the average attention span of a person dropped from 12 seconds to 8 seconds.

4. False-Consensus Effect

The False-Consensus Effect is a tendency to project one’s own behaviors and reactions onto users. So,testing with real users is an essential part of the design process.

6. Pareto Principle

For many events, roughly 80 percent of the effects come from 20 percent of the causes. In product design, the Pareto Principle can be applied to optimization efforts, when a designer should concentrate on the most valuable features.

7. Fitt’s Law

If the designer wishes the element to be easily accessible, the element should be large enough, and positioned close to users.

8. Hick’s Law

In 1952, psychologists Hick and Hyman found that the more stimuli there are to choose from, the longer it takes for a user to decide which to interact with.

9. Weber’s Law of Just Noticeable Differences

The law shows that users dislike a massive change in products they use, even though the changes will benefit users. So a designer should introduce changes not all at once.

10. The Zeigarnik Effect

Russian psychologist Bluma Zeigarnik noticed the phenomenon that people remember uncompleted or interrupted tasks better than completed tasks.The effect is often used in gamification.

If these principles are applied correctly, they can help to create a better user experience for the users.
