Background

Zener cards were originally developed in the 1930s by psychologist Karl Zener for experiments in extrasensory perception (ESP) with J.B Rhine at Duke University. The deck consists of five simple symbols—circle, cross, wavy lines, square, and star—designed to minimize ambiguity during testing. Historically, Zener card tests aimed to scientifically investigate psychic abilities like telepathy and clairvoyance. While early studies sparked public interest, later research highlighted the importance of rigorous controls to avoid bias and chance. Today Zener cards remain a classic tool for exploring intuition and probability, blending psychology, history, and a bit of fun.
