Start with a cage containing five monkeys. In the cage, hang a banana on a string and put a set of 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 makes an attempt with the same result. Pretty soon, when any monkey tries to climb the stairs, the other monkeys will try to prevent it.
Now, turn off the cold water. 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. 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.
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. Why not? Because that’s the way it’s always been around here.
And that’s how company policy begins…

Great story Ian.
Here is a similar one that I’ve always liked:
The topic of his dissertation was social influence in perception, and the experiments have come to be known as the “autokinetic effect” experiments. In an otherwise totally dark room, a small dot of light is shown on a wall, and after a few moments, the dot appears to move. This effect is entirely inside-the-head, and results from the complete lack of “frame of reference” for the movement. Three participants enter the dark room, and watch the light. It appears to move, and the participants are asked to estimate how far the dot of light moves. These estimates are made out loud, and with repeated trials, each group of three converges on an estimate. Some groups converged on a high estimate, some low, and some in-between. The critical finding is that groups found their own level, their own “social norm” of perception. This occurred naturally, without discussion or prompting.

What the above quote doesn’t say is that if you start to switch out the group members with new members, they will also agree with the group norms.
The thing I like about this story is that it’s humans.
