"Unfortunately, the foundation of our statistics in psychology is the bell shaped curve, which assumes that all observations are separate and random. So the bell shaped curve will always remain an abstraction, a weak match to research phenomena in psychology, inasmuch as it is based on the concept of random variation. Similarly, Two Face will never be as interesting a character as Batman or Joker.
So is chaos bad? No. The Joker is bad! But deterministic chaos is a process that is adaptive in some circumstances and in others can create a transition from old structure to new more adaptive and complex structure, better able to take on a challenge."
