These early findings, and Davis’ conclusions, are contrary to the assumption that a pretest demonstration of polygraph accuracy enhances discrimination between truthful and deceptive responses. Subsequent research by Bradley and Janisse (1981), however, supports the use of the stimulation test. Bradley and Janisse revealed by the polygraph. These early findings, and Davis’ conclusions, are contrary to the assumption that a pretest demonstration of polygraph accuracy enhances discrimination between truthful and deceptive responses. Subsequent research by Bradley and Janisse (1981), however, supports the use of the stimulation test. Bradley and Janisse Intelligence is an additional variable which potentially might affect detectability. The ability of intelligent subjects to anticipate questions may affect polygraph accuracy. One possibility is that intelligent subjects are less detectable because, if trained, they are able to anticipate questions and employ countermeasures.
