Law of Prägnanz
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.

Where the principle shows up in a token, component or pattern decision.
A chart with four marks reads faster than one with forty — simplify the mark before adding a legend. When a visual can be read two ways, users will pick the simpler one, right or wrong.
