How accurate is it?

The Defense Department has paid for three studies of the handheld lie detector, PCASS. Here are brief descriptions. Follow the links to read the full study reports.

Test one
In the first test, Army basic trainees at Fort Jackson, S.C., were put through what's called a mock-crime drill. Some recruits were told to place a fake bomb by a roadside, while others remained inside. After a detonation was heard, each was questioned.

They were given an incentive to tell the truth: If they were found to be deceptive, they would have to give a 10-minute speech to their unit on the subject of honesty. (That threat was itself a lie.) The examiners were all polygraph instructors, and the interviews were in English.

The test was performed in three rounds: first with a traditional polygraph, then twice with PCASS.

In the first round, with a polygraph, the examiner was correct 79.7 percent of the time, or 55 out of 69. The Pentagon prefers to cite an accuracy rate that sets aside the "yellow" results, or inconclusives; that yields a success rate of 85.9 percent, or 55 out of 64. (The polygraph was uncertain in 5 cases out of 69, or 7.2 percent.)

In the second round, with PCASS, the device was correct in 63.0 percent of the cases, or 46 out of 73. The Pentagon cites an accuracy rate, setting aside the inconclusives, of 86.8 percent, or 46 out of 53. (The PCASS was uncertain in 20 out of 73 cases, or 27 percent.)

In the third round, with PCASS, the device was correct in 62.2 percent of the cases, or 51 out of 82. The Pentagon cites an accuracy rate, setting aside the inconclusives, of 73.9 percent, or 51 out of 69. (The PCASS was uncertain in 13 out of 82 cases, or 16 percent.)

Test two
In the second test, in Columbus, Ohio, civilians who answered a classified ad for a scientific study on deception. Their incentive: Participants were paid a $50 bonus if the machine showed them to be truthful. Battelle Memorial Institute, a defense contractor, was paid $305,000 to perform this test. The instructors were experienced law-enforcement polygraphers, and the participants were all American, English-speaking and college-educated.

Again, this was a mock-crime test, with the fake theft of a ring from a secretary's desk. Both those who did and didn't steal the ring were then questioned.

The PCASS was correct in 78.9 percent of the cases, or 56 out of 71. Setting aside the inconclusive, the Pentagon cites an accuracy rate of 91.8 percent, or 56 out of 61. (The PCASS was uncertain in 10 out of 71 cases, or 14 percent.)

Test three
In the third test, the algorithm that makes the decisions was tested in the lab by its creators at the Johns Hopkins University Advanced Physics Lab. The university was paid $1.2 million for its work.

The PCASS was still being developed while they wrote the software, so they had no PCASS exam data to work with. They used a set of polygraph exam records, part of the same set of records that were used to develop the device. All of these records had been independently verified, such as using urinalysis to prove whether or not someone was lying about using drugs.

For every 100 deceptive people, the researchers reported, the device would detect 86 (red), with two false negatives (green) and 12 uncertain (yellow).

For every 100 truthful people, they said, it would detect 50 (green), with eight false positives (red) and 42 uncertain (yellow)."]]>Apr 9th 2008 3:37PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:40PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:41PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/
its right 3/4 of the time in mock tests.

My point is this: Everyone who just witnessed a REAL roadside bomb including the bomber are going to be incredibly stressed out and want to get away from the scene as soon as possible. That will screw up the tests even more.]]>Apr 9th 2008 3:45PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:12PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:12PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:16PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:43PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 4:02PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:17PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/

GREEN = Eye warily, let them go on their way
YELLOW = Eye warily, lock them up and ship them to a camp for further questioning
RED = Shoot on the spot. Eye the carcass warily.

Then they know they're on a lie detector (and that dude wants to shoot them as soon as the light goes red), and bingo!, they tell the truth.

It's almost as reliable at determining what is true, and exactly as reliable at procuring information.]]>Apr 9th 2008 5:19PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 5:24PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/ok so maybe lie detectors arent perfect. but why do you have to go hate on the soldiers? yes there are the few that just want to shoot anything that moves, but a lot of them probably dont want to hurt anyone. they are people and are moral. not everyone who goes into the army to kill people. i mean unless your in the army i dont see you doing anything to help that situation over there.]]>Apr 9th 2008 6:41PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 3:45PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/Apr 9th 2008 10:15PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/

How's this work in the first place? I thought that for lie detectors to work, you had to ask a bunch of meaningless question so you could see when their blood pressure goes up naturally.. Of course, anyone is going to be nervous when a soldier or a cop walks up to you accusing you of lying. So aren't there going to be a ton of false positives? *sigh* this has disaster written all over it. ]]>Apr 9th 2008 3:58PMhttp://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/http://www.engadget.com/2008/04/09/us-troops-to-receive-handheld-lie-detectors/
