Learning the Status Quo
Start with a cage containing five monkeys. In the cage, hang a banana on a string and put stairs under it. Before long, a monkey will go to the stairs and start to climb towards the banana.
As soon as he touches the stairs, spray all of the monkeys with cold water.
After a while, another monkey will make an attempt with the same response - all of the monkeys are sprayed with cold water. Keep this up for several days.
Turn off the cold water.
If, later, another monkey tries to climb the stairs, the other monkeys will try to prevent it even though no water sprays them.
Now, remove one monkey from the cage and replace it with a new one.
The new monkey sees the banana and wants to climb the stairs. To his horror, all of the other monkeys attack him. After another attempt and attack, he knows that if he tries to climb the stairs, he will be assaulted.
Next, remove another of the original five monkeys and replace it with a new one. The newcomer goes to the stairs and is attacked. The previous newcomer takes part in the punishment with enthusiasm.
Replace the third original monkey with a new one. The new one makes it to the stairs and is attacked as well. Two of the four monkeys that beat him have no idea why they were not permitted to climb the stairs, or why they are participating in the beating of the newest monkey.
After replacing the fourth and fifth original monkeys, all the monkeys which have been sprayed with cold water have been replaced. Nevertheless, no monkey ever again approaches the stairs.
"Because that's the way it's always been done around here."
The 100th Monkey
The Japanese monkey, Macaca Fuscata, had been observed in the wild for a period of over 30 years.
In 1952, on the island of Koshima, scientists were providing monkeys with sweet potatoes dropped in the sand. The monkey liked the taste of the raw sweet potatoes, but they found the dirt unpleasant.
An 18-month-old female named Imo found she could solve the problem by washing the potatoes in a nearby stream. She taught this trick to her mother. Her playmates also learned this new way and they taught their mothers too.
This cultural innovation was gradually picked up by various monkeys before the eyes of the scientists. Between 1952 and 1958 all the young monkeys learned to wash the sandy sweet potatoes to make them more palatable. Only the adults who imitated their children learned this social improvement. Other adults kept eating the dirty sweet potatoes.
Then something startling took place. In the autumn of 1958, a certain number of Koshima monkeys were washing sweet potatoes -- the exact number is not known. Let us suppose that when the sun rose one morning there were 99 monkeys on Koshima Island who had learned to wash their sweet potatoes. Let's further suppose that later that morning, the hundredth monkey learned to wash potatoes.
THEN IT HAPPENED!
By that evening almost everyone in the tribe was washing sweet potatoes before eating them. The added energy of this hundredth monkey somehow created an ideological breakthrough!
But notice: A most surprising thing observed by these scientists was that the habit of washing sweet potatoes then jumped over the sea...Colonies of monkeys on other islands and the mainland troop of monkeys at Takasakiyama began washing their sweet potatoes.
Thus, when a certain critical number achieves an awareness, this new awareness may be communicated from mind to mind.
Although the exact number may vary, this Hundredth Monkey Phenomenon means that when only a limited number of people know of a new way, it may remain the conscious property of these people.
But there is a point at which if only one more person tunes-in to a new awareness, a field is strengthened so that this awareness is picked up by almost everyone!
Interesting phenomena. I cant see how people outright deny that we may have a common ancestor.
