Those of us whose FBI careers have been unjustly destroyed before they started by this machine would like you to answer this question, Mr. Warner. What do you estimate your false positive rate is for Multi-issue CQT format screening exams? My FBI polygraphers all told me 0% when I asked them. I wonder if that answer would stand up to their own test? also you mention this anytime the FBI would actually like to INVESTIGATE your allegations of drug use or sale against me, I would welcome it. If you find 1 shred of evidence that I ever took any drug or sold any drug, I'll buy you a brand new GSR monitor. But you dont investigate people do you Mr. Warner?, you just trash their dreams and goals if god forbid their finger sweats when an FBI agent in a blank room asks them if they ever took any drugs.

Finally, you quote this stat

Quote:

Overall, the study showed that out of the 2,641 deceptive criminal polygraph reports reviewed, 1,316 provided no additional useful information. However, 1,325 reports resulted in acquiring confessions, admissions, or information of investigative value.

Anyone who peruses this board will find time after time that especially in the case of multi issue screening exams, many of the people who have educated themselves about polygraph assign it about chance accuracy in this format. chance accuracy is another way of saying a coin flip or 50%. YOUR STATS SAY THAT OUT OF 2600 CASES, 1300 CONFESS TO SOMETHING. the irony of your proof is amazing. yes, im sure that a portion of the 1300 who didnt admit to anything are lying, but what %? the point is you have no idea and if you thing that wrecking the aspirations of every 3 or 4 out of 10 applicants is aceptable, then to hell with the FBI.

i think this sums it up

Regardless of its validity or reliability, polygraph testing offers investigators another tool

at least you admit its a prop
