PROFESSIONAL POLYGRAPH TEST QUESTIONS USED BY LIE DETECTOR COMPANIES
Lie detection companies mostly use professional polygraphs because of their high success rate and hence reliability. The questions they use to test the subject have to take on a particular form which should serve the appropriate purpose.
The following is the nature of professional polygraph test questions. Yes/No
Questions asked during a polygraph test should be yes or no answers only. Due to fictitious representation of interrogations in movies or TV many people have a skewed idea of what a true polygraph test looks like. There are no questions that require a narrative answer. A person who is asked such a question during a polygraph test has the right not to answer it. The questions should not probe the subject for expressions of opinion or feelings. That would be a compound question and that should not occur during a professional polygraph test. Moreover, there should be no hypothetical questions.
Interview vs Interrogation
Professional polygraph test questions should make the subject feel that he is being interviewed and not interrogated. The difference is that an interrogation is forceful and confrontational where the subject is being asked to admit wrongdoing. On the contrary, an interview takes on a cool and objective demeanour. In an interrogation, the questions cannot be revealed beforehand whereas in an interview, the examiner should go over the questions with the subject to ensure that there will be no confusion during the interview. Polygraph test questions should be modelled as in an interview.
Professional polygraph test questions should be structured in a way that helps the questioner determine the truth. The questions should be structured in a way that leads the questioned on to a foregone conclusion. The aim of the questions should be to determine whether the subject is lying and not to trip him/her up or lead him/her to a confession.
This is where the TRUTH starts.
