Laws of UX

01

Users often perceive aesthetically pleasing design as design that’s more usable.

03

The time to acquire a target is a function of the distance to and size of the target.

05

Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.

07

People will perceive and interpret ambiguous or complex images as the simplest form possible, because it is the interpretation that requires the least cognitive effort of us.

09

The human eye tends to perceive similar elements in a design as a complete picture, shape, or group, even if those elements are separated.

11

The average person can only keep 7 (plus or minus 2) items in their working memory.

13

The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes.

15

People judge an experience largely based on how they felt at its peak and at its end, rather than the total sum or average of every moment of the experience.

17

Users have a propensity to best remember the first and last items in a series.

19

The Von Restorff effect, also known as The Isolation Effect, predicts that when multiple similar objects are present, the one that differs from the rest is most likely to be remembered.
