Etymology
The term 'polygraph' derives from the Greek words 'poly', meaning 'many', and 'grapho', meaning 'to write'. The device was first developed in the early 20th century, with its most notable advancements occurring in the 1920s by John A. Larson, a medical student, and later by Leonarde Keeler. Initially, polygraphs were used primarily for research in physiology but later found their applications in criminal investigations. The technology behind the polygraph has evolved significantly, yet its controversial nature continues to provoke debates regarding its reliability and ethical implications in law enforcement and employment practices.
