Have you ever heard the theory of the 100th monkey?
In the 1950’s biologists and anthropologists were studying the behavior of a species of monkeys that live on some of the outlying islands around Japan. In order to gain the confidence of the monkeys and get close enough to study their behavior, the scientists would place sweet potatoes on the beach. The monkeys adored these moist potatoes (called batatas), but disliked the sand clinging to them. One day an adolescent female monkey (about eighteen months old) on the island of Koshima, solved this problem by washing her batata in fresh spring water.
She taught the “trick” to her mother, and then to her playmates, and over a period of time most of the monkeys on the island learned to wash their batatas to get rid of the sand. At this point perhaps 99 monkeys had been trained in this behavior. One day the 100th monkey learned how to wash his batata. By the next day every single monkey on the island of Koshima was doing this – even the ones who lived a bit more isolated from the others and had never witnessed a demonstration.
But what was particularly astonishing was that this new behavior was suddenly observed in the populations of these same species of monkeys on the other islands. Every monkey in the remote outlying islands was washing away the sand on their sweet potatoes without ever having been taught how to do it!
The number 100 may not be exact, but the theory of critical mass evolved from this study: That once a certain number of a species learns a new behavior and that number reaches a critical mass, it can spontaneously be transmitted to all members of the species. This was very encouraging to metaphysicians and philosophers, who envisioned a time that a significant percentage of the human species, having learned to live with one another peacefully and harmoniously, would reach a critical mass and transmit this behavior to all of humanity. I first learned about this study about the time I opened my private practice in LA in the mid-80’s. I so enthusiastically embodied the ideal of the 100th monkey, that whenever I treated a new patient I would think “maybe this is the 100th monkey. Maybe if he or she can learn to take responsibility for the state of the world and make the appropriate inner changes, the world will become a better place.”
