Nevertheless, a study has shown that there is no precise physiological result related with lying and that the brain activity and mechanisms connected with lying are unidentified, making it hard to identify aspects that separate liars from truth tellers. Lie detector examiners also desire to employ their individual scoring technique, as divergent to program methods, as they might more easily guard their assessments.

Due to this reasons, many people prefer to use other methods of lie detection instead of employing the use of lie detector machines. 

The assessor begins polygraph test sessions with a pre-test discussion to get some groundwork information that will afterward be utilized to build up pinpointing questions. Then the tester at will give details on how the lie detector is supposed to work, stressing that it can identify lies and that it is essential to respond honestly.
