A rare card game with fanciful illustrations themed around the horse Clever Hans, whose owner, William von Osten, claimed it could do arithmetic including addition, subtraction, fractions, as well as many other things like understand spoken German and keep time. The ensuing Clever Hans phenomenon hit America with a New York Times article in 1904. The horse's supposed abilities were not conclusively debunked until three years later, by psychologist Oskar Pfungst, who learned that the horse's trainer had been passing him all manner of subtle cues he himself was unaware of. "The Clever Hans effect" was the term coined to describe the observer-expectancy effect, and it is still used to this day. Item #140941086
