The results with a 99.9% accuracy claim are just a marketing trick used by some polygraph examiners aiming to attract clients by any means. The actual, honest accuracy rate varies from 85% to 97%. In each specific case, a polygraph examiner carefully analyzes the client’s situation and develops an individual testing system, avoiding the use of outdated templates. The daily experience of over 700 members of the European Polygraph Association allows us to improve the methodology of conducting examinations, making us leaders in the field of lie detection throughout Europe.
