Oskar Pfungst

Oskar Pfungst was a German psychologist best known for his work in experimental psychology and animal behavior. His notable book, "Clever Hans (The Horse of Mr. Von Osten)," investigates the famous horse that appeared to perform arithmetic and other intellectual tasks. Through rigorous experimentation, Pfungst revealed that the horse's abilities were largely due to unintentional cues from its handler rather than genuine understanding. This work contributed significantly to the fields of psychology and animal cognition, highlighting the importance of critical observation and skepticism in experimental research.
