Good design

“Two of the most important characteristics of good design are discoverability and understanding.”

― Donald A. Norman, The Design of Everyday Things

One of the most intelligent case studies in design is the Chinese tea cup. They’re made without handles simply because if it’s too hot to touch, it’s too hot to drink.

Humans naturally want to add more. Add a cardboard sleeve, add a warning on the outside of the cup, add a handle. The result of all these things never cools down the actual contents.
