The Principle of Compatibility’s Corollaries

Because hue is metathetic variable, variations in hue aren’t seen automatically as signaling different amounts of a quantity.
Animation interferes with comprehension if it does not fit the natural movements of the object (for example, a picture of a car should not drop down from the top), and sounds and slide backgrounds will interfere if they are not appropriate for the topic (the sounds of birds chirping, isn’t compatible with a presentation about exercising in a gym).
Viewers most easily interpret icons that depict the typical examples of represented items. For example, a picture of a duck effectively illustrates “waterfowl” but not “domesticated bird,”.
Old-fashioned looking font would send a conflicting message if used in a high-tech device.
Because they make different sorts of information explicit, different sorts of graphics are appropriate for making different points. Line graphs (as opposed to a bar or mixed graph) illustrate trends effectively because the continuous variation in the height of a line in a graph directly indicates the continuous variations of a measurement. Charts effectively illustrate organizational structure, a sequence of steps, or processes over time (“flow charts”).
