What is polygraph?

A polygraph will collect physiological data from at least three systems in the body.

What is a typical polygraph?

A typical polygraph examination will include a period referred to as a pre-test interview, a chart collection phase, and a test data analysis phase.

What is the best way to prepare for a polygraph examination?

A person should get an adequate amount of sleep before the examination. You should use all prescribed medication as directed by your doctor. You should not use alcohol or drugs within 24 hours of the examination.

How accurate is a polygraph examination?

A properly administered polygraph examination has been proven to be over 90% accurate for a single-issue examination. While most cases will be determined to be truthful or deceptive, occasionally an examination will be Inconclusive. This means that based on the physiological data, no opinion can be rendered as to the truth or deception.
