Lie detection is said to be less than 100% for proving if some one is lying but apparently there may be legally means of using chemicals such as sodium penthanol which may be 100% effective.

detect lying, lying truth, why people lie, Body Language
By observation. When a person lies, his pupils will dilate. This is because, when you lie, the innate excitement will cause a release of epinephrine and norepinephrine (adrenaline and noradrenaline). This causes pupilar dilation. Secondly an MRI can be used to detect lies. This is because, lying is a creative process unlike telling the truth. So there is an increased brain activity when a person starts to tell a lie and the MRI will light up at the creative part of the brain.

Um…. No way i bet… Now and then lie detectors are wrong aslo ha ha ha ha ha
there is no 100% method, even sodium pentothal isn’t 100% guaranteed
if you want to use it on a gf/bf, then ask him/her some questions regarding the suspicious incident, record everything he/she says. after a few weeks, ask the same question again and try to match them up. chances are that if the person is lying, not everything will match up…
It has been proven that polygraphs (lie detector) are not always true. People have tested it many times, and it has NEVER been 100% accurate. If someone makes themselves think they did something it will show up that they did it. Or, if someone did something, then totally blocked it out of their head and told themselves they didnt do it, it would show as if they didnt.
