 In an ideal world, a lie detector1 machine would measure some involuntary response which everyone has when they lie, but not when they tell the truth. Unfortunately, there is no such response and, because of this, no such thing as a perfect lie detector. The so-called lie detector tests you’ve heard of are usually polygraph tests. How does this test work, and how accurate is it? A polygraph generally measures four things. Electrodes on your palm measure how much you sweat. A rubber tube strapped2 around your chest detects changes in breathing. A blood pressure cuff3 measures both pulse and blood pressure. During the course of the test, the examiner usually asks about a dozen questions. Most of these are neutral–like “What is your name?”–but mixed in are the important questions–”Did you kill your wife?” for example.
