Zener Cards

The classic ESP test. 25 face-down cards, five symbols. Feel each card and pick its symbol. Pure chance lands about 5; see how far past it you can go.

The history: Duke University psychologist Karl Zener designed these cards in the early 1930s for J.B. Rhine's research into what Rhine named extrasensory perception. Rhine's 1934 book Extra-Sensory Perception made them famous. Most scientists remain skeptical of ESP, so treat your score as practice, not proof.
