Five Monkeys Experiment
Since the late 1960s, the so-called "Five Monkeys Experiment", which serves to exemplify the adverse effects of unquestioned traditions, has become part of management lore, often titled "How Company Policy Is Made". It imagines a situation where five monkeys are in a cage with a banana tied to the ceiling. Whenever a monkey climbs to reach the banana, all five are sprayed with cold water. The group quickly learn to ignore the banana and punish any monkey who attempts to reach for it. If one monkey is removed from the cage and replaced with a newcomer, they too are punished for reaching for the banana. If every monkey is subsequently replaced in this manner, so that none present remember being sprayed with cold water, the group will supposedly continue to punish any attempts to reach the banana. The monkeys are perpetuating a caution that may be redundant, "because that's the way it's always been around here".
