An actuarial method for statistically determining the probable truth or falsity of a statement concerning a human subject and whether responses or statements made by the subject precede either a knowing representation by the subject of a truth or a lie. The method enables the correlation of a video image of a human subject, including mannerisms of the human subject, a selected plurality of eclectroencephalographic signals gathered from a plurality of electrodes located at specific points on the head of the subject, and a simultaneous detection or display of the subject's responses from a single video monitor combined with a computer analysis of the electroencephalographs to determine the subject's knowledge regarding a fact, a personal experience, and/or the truth or falsity of a particular statement by using a set of regression equations which establish before-truth, before-lie, during-truth, and during-lie base actuarial profiles for correlation and comparative analysis via computer. A system provides remote audio communication between the human subject and an examiner, a computer for analyzing electroencephalographic responses of the subject and comparing same with the base acturial profiles is provided and connected for receiving and sending a video image of the subjects face onto a portion of a monitor while simultaneously processing, sending and displaying the plurality of brain electrical waves on a another portion of the monitor. The electrical signals from the subject's brain are acquired using a novel disposable elastic skull cap with 19 electrodes pre-inserted in the cap in pre-selected positions. The computer digitizes each electrical signal over a unit of time and compares digitized signals for different epochs of times with the signals generated from selected epochs serving as actuarial base line signals.
