Polygraph results are inadmissible in court and are per se inadmissible as the science is not reliable. Only statements made during the examination may be admissible. It is not a truth or lie test. Physiological responses may indicate deception and can be skewed by characteristics unique to the individual or examiner bias. We have all seen those who appear perpetually nervous and others who remain calm in the most stressful situations. The problem of fairness and prejudice in terms of confusing and misleading juries is more important than probative value. The polygraph is only an interrogation tool. A tested subject can be misled into providing a confession by convincing them that the machine proves they are lying. A good reading on this, and why this is bad, is psychoanalyst Theodore Reik’s book, “The Compulsion to Confess.” The national media has provided much evidence of people confessing to crimes that they never committed. But, that’s what it’s all about. An arrest and conviction—at any cost. Case closed.
