Fourth, to harness the energies of a system, you must get to know how feedback loops work. Top-down styles of thinking and of management no longer respond nimbly and successfully to challenges: if the communication is only going in one direction, then the system gets bogged down in routines, misinformation, and mistrust. Feedback loops can occasionally work against us, as in a reinforcing loop. This is like a recording getting stuck, repeating the same line over and over again. If we are only telling ourselves one story, then it becomes dominant, and the system gets out of balance.
