A concise historical narrative of NAICS Code 423490-25 covering global milestones and recent developments within the United States.

• The history of lie detectors dates back to the early 20th century when William Moulton Marston invented the first polygraph machine in 1915. The machine was used to measure blood pressure, pulse rate, and respiration rate to detect deception. In the 1920s, John Larson, a medical student, improved the polygraph machine by adding a galvanometer to measure skin conductivity. The machine was used by law enforcement agencies in the US in the 1930s to detect deception in criminal investigations. In the 1960s, the use of polygraph machines expanded to the private sector, including the insurance industry, where they were used to detect fraud. In recent years, the use of lie detectors has expanded to other areas, including employment screening, national security, and immigration. In the US, the use of lie detectors is regulated by the Employee Polygraph Protection Act of 1988, which prohibits most private employers from using lie detectors in employment screening.
