The scientists placed monkeys in a cage with a ladder with bananas at the top. Any monkey that climbed the ladder would be punished by the other monkeys being sprayed with cold water. Over time, the monkeys formed a paradigm where any monkey that climbed the ladder would be beaten by the others, even if they had never personally experienced the cold water punishment. When new monkeys were introduced, they quickly learned not to climb the ladder due to being beaten by the other monkeys, perpetuating the paradigm without understanding its origins.
