Abstract

The purpose of this paper is to enlighten that every statement or conclusion of reliability od poligraph is high risk statement. After introductory historical remarks, in this paper has been discussed and analyzed empirical evidences of validity and reliability of polygraph testing, silent lie detector as an alternative procedure. In respectable academic article "Charlatanry in forensic speech science" (Eriksson & Lacerda, 2007) authors reviewed 50 years of lie detector research and came to the conclusion that there is no scientific evidence supporting that lie detectors actually work. According to the American Psychological Association (APA, 2014 and 2013), "most psychologists agree that there is little evidence that polygraph tests can accurately detect lies". As a result of those findings APA as an academic publisher has been removed scentific articles which used a results of polygraph research as an empirical argumentation from online databases. Ergo, accumulated empirical evidence suggest that instruments like polygraph doesn't detect lays, in statistical meaning, more than random guessing.
