LIE DETECTOR TESTING

Selecting a qualified examiner can be a difficult process, considering what is sometimes at stake. We understand the importance of this decision, and will never refer you to an untrained examiner, or one who uses a technique not validated by scientific research. If done correctly, polygraph testing is on average 90 to 95% accurate (click here to see the research). We offer only true polygraph services. Do not be fooled by offers of voice stress analysis (VSA), which the U.S. Government has determined to be unreliable
