Polygraphs

Lie detector tests, also known as polygraphs, measure human vitals as a person answers a series of straightforward questions. Supporters of polygraph testing believe that these tests can detect the physical effects of lying, such as perspiration, blood pressure, heart rate, breathing, and more. But are these tests really accurate?

There is really no way to be sure of polygraph accuracy since there are so many variables that can affect the results of a test, such as instructor experience, the format of questions being asked, the style in which the results are interpreted, and more.

Furthermore, being tested in such a way adds stress in itself; a person could be telling the truth, but the test will measure their words as a lie simply because they are nervous. So it is very difficult, if not impossible, to distinguish between physical changes that come from lying and those that come from being under the scrutiny of such tests.

Lie Detector Evidence

Basically, lie detector tests do not confirm whether or not a suspect is being dishonest, but rather, whether or not there is a possibility that they are being dishonest. Since lie detector tests do not meet the standards of dependability obligatory for scientific evidence, such results are typically inadmissible as evidence in a court of law.

To Agree or Not to Agree

Back to the original question of whether or not you should agree to take a polygraph when asked by police, the answer is always, NO. Always say “no” when asked to take a lie detector test. Instead, you must always consult with your Indianapolis criminal defense attorney before answering any police questions.
