Hello there! I recently failed a polygraph with unnamed agency and I read on this web site that the "yes test" was primarly given to those who are suspected of using countermeasures, in which, I did not! Probably should have! I was told I failed the "Have you ever sold illegal drugs?" question. (When I have NEVER sold illegal drugs!)  After two sets of questioning, I was given the "yes test." Is it possible that the examiner suspected me of cheating, when I did not? Does anyone know what the "yes test" really is? Just trying to figure out how I failed this test, any replys would be helpful!
