Zener cards

Zener cards are a set of five cards with markings on them that are used in experiments to measure extrasensory perception. The cards were developed in the 1930s by Dr. J.B. Rhine of Duke University. The markings consist of five symbols: a cross, three wavy lines, a star, a circle, and a square. The symbols are placed on the cards in a random order.

The test subject is shown one of the cards and is asked to guess the symbol on the card. The test subject then guesses the symbols on the other four cards. The results are tallied and the test subject is given a score.

Zener cards are used to measure telepathy, clairvoyance, and precognition. Telepathy is the ability to read the thoughts of others. Clairvoyance is the ability to see objects or events that are not present. Precognition is the ability to see the future.

Zener cards have been used in many experiments to test the abilities of people to read the thoughts of others, see objects or events that are not present, and see the future. The results of these experiments have been mixed. Some experiments have shown that people have the ability to read the thoughts of others, see objects or events that are not present, and see the future. Other experiments have shown that people do not have the ability to read the thoughts of others, see objects or events that are not present, and see the future.

The results of experiments using Zener cards are inconclusive. More research is needed to determine if people have the ability to read the thoughts of others, see objects or events that are not present, and see the future.
