Polygraphing: meaning, definitions and examples
🧪
polygraphing
[ ˈpɒlɪɡrɑːfɪŋ ]
lie detection
Polygraphing refers to the process of using a polygraph, commonly known as a lie detector, to measure and record physiological responses while a person answers questions. This technique is often used in criminal investigations or security screenings to assess the veracity of the subject's responses. The polygraph records various indicators such as heart rate, blood pressure, respiration, and skin conductivity, which are believed to change when a person is being dishonest. While some believe it to be an effective method for detecting lies, the reliability and accuracy of polygraph tests are subjects of significant debate in both scientific and legal communities.
Synonyms
deception detection, lie detection.

Etymology
The term 'polygraph' originates from the Greek words 'polus' meaning 'many' and 'grapho' meaning 'to write'. The modern sense of the word emerged in the 20th century as the technology for measuring physiological responses advanced. Originally, the polygraph was a device designed to measure multiple physiological variables simultaneously, hence the name. The first functional polygraph was developed in 1921 by John Augustus Larson, a medical student at the University of California. Since then, polygraphing has evolved with improvements in technology and methodology. Today, it is commonly utilized in various fields, ranging from law enforcement to employment screening, though its scientific validity continues to be a topic of discussion among experts.
