Through popular books and portrayals of parapsychology in movies like Ghostbusters, many people assume that psi experimenters today primarily use the well-known ESP cards. This is a deck of 25 cards, with five repetitions of five cards showing symbols of a square, circle, wavy line, cross, or star. Such cards were developed and used extensively in early psi experiments primarily by J. B. Rhine and his colleagues from the 1930's through the 1960's. ESP cards provided persuasive evidence for ESP, but today they are rarely used by professionals. Five of the most prolific and persuasive of the current experiments are listed in the five items below.

  1. PK on random number generators
  2. PK on living systems
  3. ESP in the ganzfeld
  4. Remote Viewing
  5. Presentiment Studies
