Are there ways to beat this machine?
I'm not aware of any technique for modifying one's voice that would ensure production of a "truthful" CVSA chart. One CVSA examiner has suggested that adopting an "I don't give a shit" attitude (pardon the vulgarity) seems to help increase one's chances of passing.
In addition, the behavioral countermeasures for polygraph interrogations described at pp. 69-74 of The Lie Behind the Lie Detector (http://antipolygraph.org/pubs.shtml) (pp. 83-88 of the PDF file) would apply to interrogations in general, including CVSA interrogations.
:) ;) yep I passed the CVSA. You all are right just act like your having a baby with the control questions and you will pass. I hope Los Angeles agencies don't look at this board :X
Guess what agency I am with? baaaaaaaaaaaaaaa!
