The body does not lie. So stated William Moulton Marston, a psychology professor who devised components for the polygraph and in 1938 published The Lie Detector Test. Marston and his co-inventors maintained that regardless of how well a person could control his voice and face, other signs such as blood pressure, heart rate, respiration and skin conductivity would betray him when he told a lie. The physiological changes, they said, were triggered by the anxiety an individual feels when he knows he is fabricating information. Marstons own work with the machine convinced him that women were more trustworthy than men, and he went on to champion the females role in society, in part by creating and writing the comic strip "Wonder Woman" (who wielded a "truth lasso," among other gadgets).
