Public Servant,

You write, "For Mr. Webb, or anyone else, to provide information on how examiners deal with the 'informed' examinees, would be quite counter-productive."

Why do you believe this to be so?

If a subject informs the polygrapher in the pre-test phase that he/she understands the function of the probable-lie "control" questions, then the whole set of assumptions on which the probable-lie CQT depends is negated. That subject will not be (falsely) persuaded that the polygrapher wants and expects a completely truthful answer to the "control" questions.

Doesn't such an honest subject deserve to know what is going to happen if he admits his "forbidden knowledge" of polygraph procedure?

When the American Polygraph Association and DoDPI refuse say what will happen to such honest individuals, you should not be surprised if the latter choose to keep such knowledge to themselves and instead employ countermeasures to protect themselves against your invalid "test."
