Humans have a bad cognitive bias/disposition. When they see someone successfully accomplish a task in a stupid way it’s hard for them to forget and they implicitly imitate the irrational or bad behavior. Animals (dogs) don’t do this. Some monkeys do. Has something to do with our mirror neuron strength?
This is a phenomenon that researchers have called over-imitation. It’s a phenomenon where you imitate too much. This is a case where you’re not supposed to be copying somebody’s idea, but just witnessing their idea is messing up your own representation of how to solve this task.
