Lie detector tests have not been proven to be accurate enough for the courts. Lie detectors can be fooled if you know how to do it. This is why they aren't considered accurate. Not everyone who lies has physiological reactions to it that will show up in the tests. A pathological liar can tell you a yarn and never bat an eye or show any of the signs the test looks for (perspiration, eleveted respiration and heart rate, etc.).

A lie detector (polygraph) test is unreliable. There a lot of people out there that can pass one hands down. Then there are those that it will say they are lying when asked their name.
Sodium penathol is the real way to go, but, can be damaging if over dosed.

Lie Detector tests are not considered admissible because they have never been proven 100% accurate and therefore cannot be proven effective.

Polygraph test results are UNRELIABLE. They measure physiological effects. If a person is naturally the nervous type, he could easily flunk a polygrapg test, even when he is telling the truth, whereas a pathological liar can pass it easily although he is lying.

Lie detectors are not admissible in court because there are people who can actually fool them.

They do use it but it is not very strong evidence because the defense could say that the man or woman was nervous which would make the test inconclussive. But they do use it. Investigators now rely on forensics to solve cases.

They are not fool proof and have alot of errors at times, so that makes them not reliable enough to use for court

They are not truly accurate, as all they really monitor is heart rate. And heart rates can be up and down for anyone under questioning. That's why they are inadmissible

They are not accurate enough to be used as proof.
