McGRAW'S NEXT CAREER AS A POLYGRAPHER?

The American Polygraphic Association should be delighted with Dr. Phil if ever he wants to take up the profession.  He has given an admirable demonstration of how the polygraph can be manipulated between the usual hostile condition and the "friendly" condition, even if the same questions are asked and the autonomic responses measured.  In this case, he was hostile to the father and friendly to the mother.  Of course the differences in his behavior were a bit crude, but no doubt he'll learn with experience.  In any case, unless the polygraph is videotaped, the judge or jury have no idea about these friendly/hostile manipulations which are possible with the CQT polygraph, but not with the GKT version (which is used in Japan for criminal casses.)

All the best, John
