How are EVP messages formed?
There is considerable speculation about this question and much of the past and present research is designed to provide a definite answer. The short answer that appears to be emerging from the research is that there is mind-to-mind communication between the communicating entity and the experimenter. The experimenter functions as a medium for this exchange in much the same way that spirit mediums bring messages to the physical. The message, itself, is then thought to be telekinetically impressed into the recording media. Even though the evidence seems to support this view, it is apparent that the experimenter is normally unaware of his or her part in this transfer of information.
