This is a short story based on an actual experiment involving rhesus monkeys. The story demonstrates the tendency for people to do things a certain way simply because “that’s the way we’ve always done them”. Sometimes it’s worth taking a step back and asking if a system is being continued because it’s a good idea or because of cultural and historical momentum that nobody thinks (or dares) to challenge. The full post from which I got this story can be found here if you’d like to check it out.
An experimenter puts 5 monkeys in a large cage. High up at the top of the cage, well beyond the reach of the monkeys, is a bunch of bananas. Underneath the bananas is a ladder.
The monkeys immediately spot the bananas and one begins to climb the ladder. As he does, however, the experimenter sprays him with a stream of cold water. Then, he proceeds to spray each of the other monkeys.
The monkey on the ladder scrambles off. And all 5 sit for a time on the floor, wet, cold, and bewildered. Soon, though, the temptation of the bananas is too great, and another monkey begins to climb the ladder. Again, the experimenter sprays the ambitious monkey with cold water and all the other monkeys as well. When a third monkey tries to climb the ladder, the other monkeys, wanting to avoid the cold spray, pull him off the ladder and beat him.
Now one monkey is removed and a new monkey is introduced to the cage. Spotting the bananas, he naively begins to climb the ladder. The other monkeys pull him off and beat him.
Here’s where it gets interesting. The experimenter removes a second one of the original monkeys from the cage and replaces him with a new monkey. Again, the new monkey begins to climb the ladder and, again, the other monkeys pull him off and beat him – including the monkey who had never been sprayed.
By the end of the experiment, none of the original monkeys were left and yet, despite none of them ever experiencing the cold, wet, spray, they had all learned never to try and go for the bananas.
