Clever Hans
The residential inner courtyard at 10 Griebenowstraße in the Mitte district of Berlin, Germany. At the turn of the 20th century, this urban setting hosted public demonstrations of the Orlov Trotter stallion known as Clever Hans (Der Kluge Hans). The horse's apparent mastery of arithmetic and human language captivated international audiences, revolutionized animal cognition research, and led to the discovery of the observer-expectancy effect ("Clever Hans effect").
