title: The Control Question Test in polygraphic examinations with actual controls for truth.
abstract: Subjects who were guilty of a mock crime, innocent and informed of the details of the crime or innocent, and uninformed of the details were examined on the polygraph with a modified version of a Control Question Test, which normally contains questions which are incriminating, ambiguous, and likely to be answered with a lie. We challenged the necessity of using incriminating, ambiguous control questions which may demand a lie as an answer. Instead, we created and tested control questions that were unambiguous and answered truthfully. The results, with the modified questions, showed correct identification of 86% of the guilty subjects and 83 to 89% of the innocent subjects.
