A ganzfeld experiment (from the German words for "entire" and "field") is an assessment used by parapsychologists that they contend can test for extrasensory perception (ESP) or telepathy. In these experiments, a "sender" attempts to mentally transmit an image to a "receiver" who is in a state of sensory deprivation .
The results of many tests using Zener cards fit with a typical normal distribution. Probability predicts these test results for a test of 25 questions with five possible answers if chance is operating: 79.3% of people will get between 3 and 7 correct. 10.9% will get 8 or more correct. One person in 73,700 will get 15 or more correct.
In a telepathy experiment, the "sender" looks at a series of cards while the "receiver" guesses the symbols. To try to observe clairvoyance, the pack of cards is hidden from everyone while the receiver guesses. To try to observe precognition, the order of the cards is determined after the guesses are made. Later he used dice to test for ...

Soal moved to a more statistical and controlled approach, firstly by conducting an experiment in which up to a few hundred persons participated at one time. [5] This involved Soal and a small group of agents enacting a scenario, playing with a certain object, reciting a poem, and so on, which the participants, situated across Great Britain and other countries, were required, at the same time ...
Helmut Schmidt (21 February 1928 – 18 August 2011) was a German-born physicist and parapsychologist whose experiments on extrasensory perception were widely criticized for machine bias, methodological errors and lack of replication. Critics also noted that necessary precautions were not taken to rule out the possibility of fraud.
They concluded the results from some of their experiments supported dream telepathy. [4] The picture target experiments that were conducted by Krippner and Ullman were criticized by C. E. M. Hansel. According to Hansel there were weaknesses in the design of the experiments in the way in which the agent became aware of their target picture.
