Beware the gut feeling that like begets like and that we should thus be able to anticipate effects

Those of us (like me [2]) who are enthralled by complexity know that like begets like is far too often untrue. I’ve constantly seen that nature creates elaborate macro patterns using only a dynamic process involving far-too-simple component parts.
