A concise historical narrative of NAICS Code 561611-10 covering global milestones and recent developments within the United States.

• The Polygraph Service industry has a long and controversial history worldwide. The first polygraph machine was invented in 1921 by John Larson, a medical student at the University of California, Berkeley. The machine was initially used to monitor the vital signs of patients during surgery. However, Larson soon realized that the machine could also be used to detect lies. In the 1930s, the polygraph machine was used by law enforcement agencies in the United States to investigate criminal cases. During World War II, the machine was used to screen military personnel for security clearance. In the 1960s, the Supreme Court of the United States ruled that the results of polygraph tests were not admissible in court due to their unreliability. Despite this ruling, the polygraph machine continues to be used by law enforcement agencies and private investigators worldwide. In recent history, the use of polygraph tests has become increasingly controversial in the United States. In 1988, Congress passed the Employee Polygraph Protection Act, which prohibits most private employers from using polygraph tests for pre-employment screening or during the course of employment. However, the law does allow polygraph tests to be used in certain circumstances, such as in investigations of economic loss or injury to the employer. In addition, some government agencies, such as the Federal Bureau of Investigation and the Central Intelligence Agency, continue to use polygraph tests as part of their screening process for employees. Despite the controversy surrounding the use of polygraph tests, the Polygraph Service industry continues to provide services to law enforcement agencies, private investigators, and government agencies worldwide.
