    Two different people who both witnessed an event are both required to take a polygraph with a certified professional operator. The session can be filmed and recorded in case there are any anomalies that look weird they can be challenged. One person(person A)passes the test. The other person(person B) tells a contradicting story to the first person and fails the test. The person who failed is then allowed to take a second polygraph, on a different day, on a different machine, with a different certified professional operator and once again fails the test. What level of confidence would you have that Person B was lying?
    I'd be fairly certain they are lying but still should not be admissible.

Questions like (have you ever taken something that didn't belong to you). From that, they can see how various things change from one question to the other.
    I know exactly how they work... all good.

    Re: Lie Detectors

    I view a polygraph in the same way I view the Scientology E-meter. Pseudo-science.

    And yet many top levels of government (CIA/FBI etc. agents) make successfully passing a polygraph examination a strict condition of employment.


    The GOP stranglehold on American government is over and accountability is now part of the governing equation. Hallelujah!

    So if our top intelligent agencies consider them worthwhile is it possible that your view of them is the problem? Any test can have an error rate. Fingerprinting, DNA... IF you're comparing this to an E-meter you don't seem to really grasp anything about it. I'd say you're giving more credibility to an E-meter than it deserves.
    Obstruction of Justice also applies to overt coercion of court or government officials via the means of threats or actual physical harm and also applying to deliberate sedition against a court official to undermine the appearance of legitimate authority.

    I believe a person sometimes with an professional assist can prepare and pass a lie detector....Maybe even with the aid of being hypnotized.

    Why? Most tests have error rates. Even a test on something like whether or not your tumor is cancerous can come back as a false positive. Does that mean it isn't scientific? Every scientific study in the world requires duplication. No matter how good of a job they do controlling the study. No matter how big the sample size is there's always an error rate.

    Possible, but not probable.

    The top intelligence agencies do not rely on such tests. The background checks are comprehensive and intrusive. The polygraph tests are a relic.

    The results at best are subjective. Lie detector tests are a tactic not actually a tool.
