"The result of polygraph examination is a testimony put forth by an expert after concluding examination on a subject who agreed to undergo the procedure. The subject of consideration here is only the results acquired in examinations conducted as part of criminal investigations, which implies the omission of pre-employment examinations, post-conviction sexual offender testing (PCSOT), and other uses. Moreover, the analysis focuses on only those examinations that ended in indication that the subject of examination was deceptive as a result of the expert using one of the comparison question techniques, or as a person recognising an event in the case of applying the Concealed Information Test (CIT) technique. Nor does the study account for the results of inconclusive examinations."(...)
