The Klingbeils wrote, The fact that our minds operate to conceal from us our own natures is thought provoking. Bruce told me that being human and having defense mechanisms is powerful and causes self-deception and affects the accuracy of gathering scientific evidence. The intervention of our minds to skew how human beings interpret their lives and their unusual experiences like spiritual healings and psychic events, was a project that Bruce and John investigated. Humans are social beings. Humans are believers.
Humans are pattern seekers.
So being human affects the accuracy of our testimony for documenting an unusual event which we have witnessed. The tendency is to either turn our experiences into mystical events or to reject them. If the scientists of the future can find a way to monitor the manipulations made by our defense mechanisms, this tool will prosper the investigation of psychic and prayer phenomena. For people who like a theological bent, one could think of some defense mechanisms as demons in our minds. These demons operate as a committee to decide what tastes, sights, and sounds should constitute reality for a human being.
