What is The 100th Monkey effect?

The hundredth monkey effect is a hypothetical phenomenon in which a new behavior or idea is spread rapidly by unexplained means from one group to all related groups.

(The idea that once a critical number of members copy a behavior or follow an idea, it will be taken on by all en-masse, automatically.)

During 1952 and 1953 the primatologists began “provisioning” the troops providing them with such foods as sweet potatoes and wheat. The food was left in open areas, often on beaches. As a result of this new economy, the monkeys eated them and developed several innovative forms of behavior.

The Observation.

The Observation.

One day an 18 months old girl named 'Imo' (one of the daughters in Koshima island's tribe) observed the eating habits of monkeys. Those monkeys were eating sweet potatoes not so comfortably, because the sand and grit sticked to them. By observing this she discovered an idea of washing them and eating. And she shared these potatoes with their mom and her mom shared to their neighborhood and it went on. They find eating them by washing is more enjoyable and more tasty and they developed the idea of eating food after washing them.

The phenomenon observed by Ken Keyes jr was not accepted.

Unfortunately, this story and it’s papers have been refuted and discredited as unreliable evidence.

But this phenomenon lives on and it used in many ways.

The Real life.

This phenomenon is used largely by marketing teams and they are successful in applying this.

For example if you saw your neighbours and friends using some products or doing some stuff you too wish the same or when you gone for a super market and saw a product you remember a TV commercial by a famous actor and believe it's true and purchase it.
