Step 2 : Answer to the question "Inventor William Marston is credited for inventing both lie-detector technology and which comic book hero?"
William Marston was an American psychologist, inventor of an early prototype of the lie detector, and comic book writer who created the character Wonder Woman. Marston created a systolic-blood-pressure-measuring apparatus, which was crucial to the development of the polygraph (lie detector). The Systolic Blood Pressure test and Polygraph test are clearly similar to a real life version of Wonder Woman’s Lasso of Truth. The Lasso of Truth, of course, is a rope used by Wonder Woman which forces people to tell the truth when tied up.
