Etymology
The term 'polygraph' comes from the Greek word 'polygrapho', which is a combination of 'poly-', meaning 'many', and 'grapho', meaning 'to write'. The polygraph as a device was developed in the early 20th century by John Augustus Larson, a medical student, and later refined by Leonard Keeler. The device was initially used in criminal investigations to measure physiological responses to questions and has since become synonymous with lie detection. Over the years, the validity and reliability of polygraph tests have been debated within scientific and legal fields, leading to ongoing discussions about their use in various contexts, including employment screening and criminal justice.
