Countries that traditionally rejected the possibility of a using a polygraph have introduced it in an active practice.

  • crimes against property;
  • crimes against public security;
  • crimes in the area of official activities and professional activities related to the provision of public services;
  • crimes against justice;
  • civil proceedings.

Such situations most of all require the conduct of forensic psychological examination with the use of a polygraph and allow to determine the degree of probability of information reported by the person; the completeness of information by a person due to the circumstances of the event under the investigation and so on.
