Daniel Webster once said, "The world is governed more by appearances than by realities, so that it is fully as necessary to seem to know someting as to know it."
The life of polygraph has been perpetuated based on this very thing. Just as the fear of the "razor blade" in the apple for halloween, the fear of the polygraph as lie detector has been its very source of life. (There never was a razor blade in an apple, and only two kids have died as a result of Halloween candy...and those were poisioned by family members.)
I believe that ending the practice of polygraph must start with knowledge of the facts, of reality. The NAS report is one thing, but it becomes essential for the common citizen to know these important facts. Those who are not in a position to face a polygraph will most likely believe, to some degree, in its validity. However, once a person has been gifted with the knowledge behind this cruel joke, they can become quite the power in changing the perceptions of the general population. When that occurs, the fallacy of polygraph begins to see its coffin.
Yes, we need people to speak. But, if we are to sit back and wait for the law enforcement agencies, in particular, to voice their honest opinions, then we will have a long wait for the ending of polygraph screening. I do not particularly agree that there needs to be a wealth of legal action, but I do agree that publicity causes quite the scene. I have commonly heard that it is the 'wheel that squeeks the loudest that gets oiled first."
We are but naive if we expect those who are in LE to, at great risk to themselves, to their careers, and to their livelihood, stand up and stop this practice. It takes a man much greater than most to do such a thing. Of course, a man of honor is one that "later regrets a discreditable act even when it has worked", but again the character of an individual who not only contemplates, but acts, is a most rare one indeed.
