Yes but the police will think that you are guilty if you do.
I think you mean a polygraph test. Polygamy is the practice of having more than one spouse. A polygraph test is a lie-detector test. It depends on the laws, in some places you can use a polygraph test as part of a legal trial and in other places you can't.

Polygraph tests can be carried out by your local police force, but the FBI and CIA generally perform polygraph tests. However, these are often only used in major cases and are not allowed to be used by members of the public without any valid reason.
Because polygraphs measure stress. The presumption is that if you are stressed, you are lying. In reality, there are many causes of stress and many reasons other than lying that one can fail a polygraph. The polygraph has been known for many years to be junk science, and the fact that it is still legal to use it is one of the shameful aspects of law enforcement and security. BTW: the polygraph does not say you are lying. The "technician" who interprets it is the one who decides that, and he or she is not even a trained psychologist.

Although they can be used in conducting criminal investigaions, the results of polygraphs cannot normally be entered into evidence in court as other types of "evidence" might be.1980 - United States v. RobertsThe prosecutor had told the grand jury unequivocally that polygraph results were inadmissible in a court of law and the court called her on the carpet and stated that her statememnt was false and said "The Court dissapproves of the prosecutor's bold statement to the Grand Jury that polygraph evidence is inadmissible at trial. Such statements are absolutely untrue. The Ninth Circuit has held that polygraph evidence is admissible within the trial court's discretion."As current law stands it is up to the trial judge as to how he or she will handle any motion to admit polygraph evidence.However Legally in all 50 States of the US you can refuse to submit to a polygraph test and the fact that you refused the test can't be used against youin a court of law..But if you take the test it could be used against you if the trial judge decides to allow it.If a grand jury is reviewing the evidence to see if sufficient data exists to proceed with a trial they can use the results of a polygraph test in their recommendation to no-bill or indict. In my experience the accused should always appear before the grand jury and/or take a polygraph. Passing a polygraph will almost always get a no-bill. Failing it or failing to take one will usually result in an indictment.

US supream court deemed the "Lie detector" test inadmissable as evidence because it isn't an exact science. It is unreliable and can false-test positive even when no one is connected to it.
