Canadian Uses of the Polygraph

Although not admissible as evidence, the polygraph is used in Canada both in its confession-inducing capacity in the case of crimes (a Toronto police polygrapher once memorably testified that he regarded himself as an interrogator with polygraphic training (i.e., the polygraph is a useful interrogatory prop), as well as in civil disputes where the polygrapher can either be “hostile” or “friendly”. In criminal cases it’s actually useful for the Canadian polygraph industry that it is not admissible as evidence, as it is therefore also not open to cross examination. So just as the ancient Roman critics were not able to inquire into the details of a specific entrails-reading “test”, so the specifics of a specific polygraph “test” are also shrouded in mystery, while the social disease that this piece of superstition spreads permeates all of society, as any citizen can get into a dispute with another citizen.
