How To Use Rhine Cards For ESP Testing You now have a deck of twenty-five Rhine cards. There are three types of ESP you can test for with these cards. Your results will probably be more accurate if you have three people participating in the experiment; one "sender", one "receiver", and one "observer". The "sender" handles the cards; the "receiver" reports which cards he or she thinks are being handled; and the "observer" records the data. The sender and receiver should not be able to see each other; they should sit with their backs to each other, or even in different rooms. 1. Telepathy The sender shuffles the cards thoroughly. Then he takes one card at a time and turns it face up. He records which card it is, and concentrates on the card for a short time. The receiver attempts to "read" the sender's mind and tell which card is being viewed; she records which card she thinks the sender is viewing. Continue until the deck is used up. Compare the two lists. 2. Clairvoyance The sender shuffles the cards thoroughly. Then she takes one card at a time, WITHOUT LOOKING AT IT, and puts it into a different pile, keeping them in the order they were. The receiver records which card he thinks has been turned up. When the deck is used up and the receiver has completed his list, the sender or the observer takes the deck and records the actual order of the cards. Compare the two lists. 3. Precognition. The receiver records a sequence of twenty-five cards in the order she thinks they will be dealt. THEN the sender shuffles the cards, and records the actual order produced by the shuffle. Compare the two lists. In all three types of experiment, the score that would be expected from pure chance is five correct out of twenty-five. However, the score on one run is meaningless. Keep track of the scores for at least one hundred runs of one type, with the same sender and receiver. Only if the score is significantly higher or lower than an average of five correct per run is there any evidence of ESP.
