Full Idea
Barsalou (1983,1985) introduced the idea of ideals instead of prototypes. An ideal is a body of knowledge about the properties a thing should possess (rather than its typical actual properties). ... A 'bully' might be perfect, rather than typical.
Gist of Idea
Maybe concepts are not the typical properties, but the ideal properties
