Aesthetic-Usability Effect
Design Principles
People perceive attractive things as easier to use, whether or not they are.
In practice
The aesthetic-usability effect, observed by Kurosu and Kashimura, is the tendency to rate visually pleasing designs as more usable and to forgive their flaws. It cuts two ways: good visual design buys goodwill and patience, and it can mask real usability problems in testing. The lesson is to invest in aesthetics and to test usability with the aesthetics stripped out.
