About Global Polygraph

Worldwide since 1987

LIE DETECTOR TESTING

Selecting a qualified examiner can be challenging, 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

Fraud Alert

Do you think $145 per test is a bargain? Think again. Most of those "discount" examiners never attended polygraph school. Avoid being scammed.

Relationship Tests

Truth About VSA

Don't be fooled by offers of Voice Stress Analysis (VSA) or "over the phone" lie detection. You'll get the same accuracy by flipping a coin.
