The Lie Detector

In his writing, Lie Detector, Lewis Thomas writes how the Lie Detector (the machine) is a new great tool that can recognize if one is telling a lie by monitoring the heart beat, skin conductivity and other means. Thomas, thus concludes, through scientific means, that lying is biologically incorrect. That our body changes whenever we tell a lie. And thus we humans naturally have a compulsion to be moral.
I agree that we are biologically made not to lie. But I also disagree, because Lie Detectors are not 100% and trained CIA and other agencies can be trained to lie and not be detected. Maybe 99% of the population biologically has a response to lying and maybe 1% of the population who is superior and illicit no response when lying. Any person trained to beat the Lie Detector test is somewhat superior to a person who is not trained to beat it. Thomas did not speak on this technique (beating the Lie Detector) and was probably not aware of it.
