Hans only answered correctly when questioners knew the answers

Clever Hans, the clever horseAn Investigation

Conclusion: Hans was receiving some type of information from questioners Hans had been unintentionally conditioned by his owner

Impact:Scientists more skeptical of mental processes in

animalsBut…Provided proof that animals were capable of learning
