The Aesthetic-Usability Effect (AE) is a principle that a product that is beautiful is generally perceived as being easier to use than a product that is not. This principle is based on research that shows that people tend to judge the usability of a product based on its aesthetics.

The Aesthetic-Usability Effect has been shown to apply to a variety of products, including websites, software applications, and even everyday objects such as tools and kitchen appliances. In general, products that are more aesthetically pleasing are rated as being more usable than those that are not.

This is why beautiful-looking products that seem easy to use are preferred over usable-but-not-beautiful ones or the ones that look “hard” to use.

The MRI machine is actually a scary-looking machine but it looks not so scary because of the decoration and plastic on top.
