I mean ... technically creativity is just propensity for low probability actions given the context which the broader society evaluates with a high score because it identifies some kind of value in the outcome. If society deems the result as devoid of value, well, you reach "insanity", and if the variance is low, you reach fixed and standardized patterns. The novelty in "creative" efforts / endeavours is just enough to excite our branch predictors without being too chaotic. Too chaotic, and you reach insanity, or "garbage" until the broader society catches up. One can argue that, in part, this is why many of the greats only became so post-mortem.
