Penn and Teller did an episode of bullshit on this. The key is to clench your anus muscles. Immediately spikes the charts. Just keep doing that to every question and all of their data is invalid.

Ah, the Kegel defense.

That is not quite a nuanced enough approach to be effective. First of all, what you have to do is determine which questions are "control" questions. These are questions where the interregator expects less than 100% honesty, and they use responses to these questions as a comparison when asking you the "relevant" questions. For example, they might ask "Have you ever lied to get out of trouble?", or "Have you ever revealed a secret told to you by a friend?" You use your false-positive triggers on these questions, exaggerating the response the interrogator will associate with deception. [Edit: To clarify, the point here is that you don't want to give the interrogator a high entropy data set; that would just lead to them thinking you were lying at random. You want their data to give a very specific indication: that you have been truthful on all relevant questions] Secondly, the latest edition of The Lie Behind the Lie Detector[1] notes that examiners have begun using sensors to attempt detect physical countermeasures, such as sensors to detect changes in weight distribution. It has not been determined if they are able to detect intentional anus constriction, but in the interest of caution, they advise sticking to mental countermeasures and tongue-biting, which definitely cannot be detected (although I would expect some attempt to detect the latter in the future). Finally, it's really important to remember that these examiners are interrogators. The lie detector is a tool that they use, and in many ways it is a misdirection. One of its key purposes is to make you feel that they have an edge. Knowing that you can fool it is an important piece of the puzzle, but you must always remember that their bottom line is to get you to make damaging admissions. They are well-trained at this, and they will certainly use other techniques besides their toys.

  Those control questions don't even make sense to me because I don't see how you would expect dishonesty in answering those questions. The answer is yes for every human on this planet so why would I try and lie about something that I also have in common with the person interrogating me.

    Yes, quite.
