Quote from: George_Maschke on May 08, 2013, 11:34 AMWhat I described is no deviation from the polygraph technique, it is the polygraph technique, as taught by DoDPI/DACA/NCCA.Hmmm, George, I cannot seem to find where this is true. The DoDpi handbook does not mention this for the ZCT. They refer to numerical scoring, global scoring and the ROSS. I cannot find anything where a single spot can be used to call a particular question as deceptive.
