Considering the Gov use of CVSA, I have to ponder once again about the validity and reliability of CVSA in detecting deception. Considering the Gov is sending people for CVSA training, I presume the Gov is now taking the position CVSA is 'significantly' better than 'chance' at detecting deception.

Has there been some recent 'governmental' research (other than by the AirForce), that suports 'better than chance levels' that I'm not aware of?

Any DOD people out there aware of CVSA being used for anything other than research? I hope not.

You know George would not post it if it wasn't true!!!!!!!!!!!!

The feds contract out a lot of the security over there. I'll bet it is the contractor's employees who are being trained and not actual people on the federal payroll. The CVSA people are not beyond taking the credit they don't deserve as well.

They can only use it as an interrogation tool. They are not allowed to make any determination as to truthfulness or deception.

At least this is what I was told.

assuming DOD is using CVSA, it is no doubt a simple tool in the "spook" dept and not in the investigational arena.

Hey, common! If you can make someone, like a spy or terrorist believe it works why not use it to protect us and the troops.

As for actual "lie detection", they'll (probably) stick to polygraph. Though giving CVSA any credibility is a dangerous thought.

Thanks for making the inquiry. I must say however I ‘suspect' they are making a NDI / DI decisions though; otherwise ‘how would they know whether or not to continue with the interrogation?' The use of CVSA as an ‘interrogational tool'- sounds pretty close to what we sell the polygraph on- being a ‘investigative tool.' I wonder if someone from DoD is keeping "stats" on the accuracy of CVSA somewhere ? If I'm not mistaken the Air Force did a research study on CVSA, and found that it does detect ‘stress' in the voice, but could offer no conclusions about detecting deception.

I think they use the CVSA like they used to use the copy machine. They probably tell everyone they are lying and go for a confession.

What I don't think they are doing is reporting to someone and saying, "based on the results of the CVSA test this person is lying".

Sorry, but the CVSA was never tested by the Air Force Labs in Rome, New York. The NITV, the people making/marketing teh CVSA were asked for permission to participate in the research but refused. In fact David Hughes, Executive Director of the NITV, and Charles Humbles right hand man, wrote a very strong letter threatening to sue anyone giving the Rome Labs access to their devise. If anyone is interested I am sure I can pull part of that letter out of an article that was published by the American Bar Association in one of their journals.
