Marcusson-Clavertz recently conducted a modified Ganzfeld ESP study in hopes of examining how hypnotizability and altered states of consciousness might affect the ability to use ESP. Using the Ganzfeld method, which has excellently controlled for mistakes and errors in psi research over the last several decades, these researchers recruited 14 highly hypnotizable individuals and 12 individuals resistant to hypnosis. Each participant went through a series of procedures to test for ESP.
Results for this study showed that for people who are easily hypnotizable, the belief in ESP success, prior ESP experiences, and the ability to enter an altered state during the ESP task were significantly related to the participant’s ability to perform in the ESP task. In contrast, for those who were not easily hypnotizable, only belief in the ability to perform ESP and belief in the success of the task were associated with ESP performance.
In sum, the current research shows a relationship between those who can alter an altered state of consciousness or be hypnotized appear to have an advantage in performing ESP tasks in laboratory conditions.
