ESP Symbols: An Entire Language For Psychic Spies?: A Key for Decoding the Secrets of the Ages

The traditional five symbols of ESP experimentation are in fact a language, and until now this fact has been a carefully hidden secret. Developed by psychologist Karl Zener in the early 1930s, purportedly as a tool for extrasensory perception research at the Rhine Institute, the five symbols actually encapsulate an entire alphabet. By the 1970s, skeptics discredited the Zener system, thereby discouraging focus on the symbols and effectively sealing their (newfound?) secret importance as a coded messaging system between governmental psychic spies.
