How effective is evaluating voice stress as a form of lie detection?

2019-06-28T15:09:32-06:00

This type of test is based on the premise that muscles in the voice box tighten or loosen, which changes the sound of the voice. The small, involuntary frequency modulations in the voice when under stress (i.e., lying) are measured. Studies show that this type of tests operates at about a chance level or slightly

Aptitude tests determine if a person is apt to do the job. In other words, can the candidate perform a job function? Predicting if someone will do the job is a challenge. Predicting if someone will lie, cheat or steal is also a challenge. The premise behind EyeDetect is that is indicates recent, past behavior.

How effective is intuition as a lie detector? In other words, can you observe someone to tell if they are lying?

Studies say that humans have an accuracy rate of 54% for catching liars. (Source: Bond & DePaulo, 2006) If that’s true, you’ll get the same results from chance, or in other words, from the flip of a coin. Behaviors such as gaze aversion, touching the body or face, or covering the eyes or mouth while

How accurate is the electroencephalogram or fMRI as a lie detector?

2019-06-28T14:58:36-06:00

Research shows that an electroencephalogram and the fMRI may achieve results of 87% accuracy. However, both test are invasive (the examinee is connected extensively to medical instruments or is inserted into a large tube). Both methods are very costly, require expensive equipment and extensive examiner training. For these reasons, neither is a viable lie detection
