Good Reminder

Here is how the experiment went:

1. Start with a room containing five monkeys. In the room, hang a banana on a string and put stairs under it. You don't need to wait long and a monkey will go to the stairs and start climbing towards the banana.
2. Now, as soon as the monkey touches the stairs, spray all the monkeys with cold water as punishment. After a while, another monkey gives it a try with the same result – all the monkeys are sprayed with cold water.
3. Next step, 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 at them.
4. Now, remove one monkey from the cage and replace it with a new one. The new ape sees the banana and wants to climb the stairs. To his horror, all of the monkeys attack him. After another attempt and attack, he knows that if he tries to climb the stairs, he will be punished.
5. 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 newcomer takes part in the punishment with enthusiasm.
6. Again, replace a 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.
7. After replacing the fourth and fifth original monkey, all the monkeys that were sprayed with cold water have been replaced.

Nevertheless, no monkey ever again approaches the stairs, but no one really knows why. All the original monkeys who experienced the water-spraying punishment have been replaced. What we're left with are five monkeys who know that they can't touch the banana, but they don't really know why. Because that's the way it's always been done around here.
