Polygraph - Lie Detector Test

Protect your rights when it comes to polygraph tests

A polygraph is a machine used to detect lies. It is used by means of assessing several physiological reactions in a person to determine if they are indeed telling the truth. The machines intake blood pressure, respiration and overall skin conductivity to supplement an investigation or questioning. It is said that polygraph tests are between 70% and 90% accurate.
