We respond to Furedy's article in this journal where he raised an issue
he referred to as the "Polygrapher's dilemma" (Furedy, J.J. (1993) Int.
J. Psychophysiol., 15: 263-267). Furedy claimed that the control
question test, the most commonly applied psychophysiological detection
of deception test, is inherently subjective and harmful to subjects in
both the field and the laboratory. Fortunately, Furedy's arguments were
based on inaccurate representations of the control question test and on
flawed logic. To correct Furedy's misrepresentations, we present an
accurate description of how the control question test is used and
evaluated. We then examine the results of empirical research that
address Furedy's concerns. Furedy's concerns are found to be lacking on
almost all counts. Finally, we discuss the findings from several studies
that Furedy failed to mention but are directly relevant to the issues
he raised.
