Creativity has commonly been thought of either as a set of domain- general skills that can be applied broadly like a special kind of intelligence or as a general personality trait that colors a person’s approach to any kind of task or problem, but these ways of thinking about creativity are misleading. A better metaphor for creativity than either intelligence or a personality trait is expertise.
