Corporate Culture – 5 Monkeys and a Banana

by Margo Boster

Have you ever wonder why certain things are as they are in your work environment?   I often share the story of five monkeys and a banana.  An experiment is conducted in which five rhesus monkeys were placed in a cage together with a banana hanging high on a rope outside the reach of the monkeys.  A step ladder was placed in the cage that would enable the monkeys to reach the banana.  Whenever one of the monkeys attempted to climb and reach for the banana, ALL monkeys were sprayed with freezing cold water.

After a few attempts, all the monkeys learned the association between reaching for the banana and the group collective punishment of being sprayed with freezing water.  There was no longer need for the water; no monkeys would attempt to reach the banana.

The researcher then replaced one of the five monkeys with a new monkey. The new monkey, not aware of the icy water treatment, tried to reach for the banana. Within a fraction of a second the other four monkeys attacked him again and again, until he no longer tried to reach the banana.  One by one, the monkeys who had experienced the original icy water treatment were replaced by a new monkey.  With the introduction of each new monkey, the other monkeys would attack him until he quit trying for the banana.

Eventually, the cage was populated by five new monkeys, none who had experienced the icy water treatment.  The experimenter then introduced a new monkey to the cage. When this monkey tried to reach for the banana, all five monkeys attacked him.

The story goes that even though none of these monkeys knew about the collective punishment of icy water, somewhat along the way they learnt that reaching for the banana is not allowed. They become the guardians of this rule without knowing its purpose.

Culture is created over time, and often habits and practices areCulture Picture instilled and repeated without anyone knowing the origin of the behavior.  But to be accepted, most people diligently follow the behaviors or the others in the group will work to reinforce and maintain the current culture.

Next time someone says, “That isn’t how we do things here,” ask the question “Why?”  It may generate some interesting new thoughts and discussions.  If not, tell them about the five monkeys and the bananas.

    I’ve seen many with the same comment that this never happened because they don’t have the documented study, and or link.
    Absence of evidence is not evidence of absence. The critics have not provided any proof that this did not happen. They fail to provide in the same manner they criticize the lack of evidence of this study. It’s possible it did not occur but the evidence it DIDN’T is just hearsay and conjecture.
    Provide something that would hold up in court.

    This story is very interesting. It made me think a bit more about culture and why we even do things in culture. However, if this experiment was actually conducted, it would be cruelty to animals.

    hmmm… is it true? i have learnt from another story similar.

    one day, a scientist placed a rat in a cage, which was long. the rat was a one end, while a hunk of cheese was on the other end. when the scientist released the rat, it ran towards the cheese eagerly and chomped it up. then, the took the rat away. the then placed another hunk of cheese again at the same place, but this time, they put a pane of glass in front. they took back the same rat and released him again. the greedy little squirt ran off again, happy to get more cheese. however, it slammed right into the glass barrier. it tried again and again, but the cheese remained unharmed. then, they removed the dazed rat out of the cage and got rid of the pane. then, he put the rat back in again. this time, the rat did not run towards the cheese. this proved that animals learn from experiences too.
