Flexible adaptability is a principle of cognitive economy, posed by Dirk Geeraerts as a primary feature of prototype categorization. According to this principle a cognitive structure also be flexible enough to keep up with the constantly changing states of affairs in the surrounding world. This principle should account for the dynamism of human categorization which allows humans to allow us to learn new things, thus constantly reshaping cognitive structures.
