The presence of the machine changes the nature of the interview. It's like how being interviewed on the phone at home and being interviewed handcuffed to a table with a gun your head are different. It really doesn't matter much if the interviewer actually intends to shoot you or not. The mere presence of the prop induces stress making it difficult to think clearly and avoid being manipulated by the interviewer. To succeed in the situation your mind must be prepared to deal with the gun or the handcuffs or the polygraph. I doubt many people are able to simply ignore them.
