Thelie detector measures and records various physiological parameters such as blood pressure, pulse, respiration and skin condictivity etc. of a person against whome the device is applied during conversation. The measurements are poisted to be indicators of anxiety that accompaniesthe talking of lies. Thus the measured anxiety is equated with truth.If a person has controlled his anxiety level voluntarily the measurement may go wrong and we will be making an unreliable conclusion!
