Dr. Birtchnell proposes the existence of an unconscious, automatic, inner brain that monitors the relating objectives. He argues that the psychotherapist assists the person, through the conscious, outer brain, to correct and improve the inner brain's least effective relating strategies. He uses the term interrelating to describe the interplay between the relating of two or more people. This has application in couple, family, group, and community therapy, in which the psychotherapist's task is to enable the interrelaters to understand and correct their mutually reinforcing, destructive interactions. He introduces a set of questionnaires, from the scores of which a computer can print out an easy-to-read diagram of the direction and degree of people's relating incompetencies.
