Yes, they can be which is why they're not allowed to be used as evidence in court.

Yes, they can be fooled in a technical sense. The how's and why's are a bit different though. If you're taking the polygraph in a criminal case the results in beating the system can be different in a polygraph for a job.

As above, it won't hold up in court. Cops use them to more or less verify what they suspect as is, or as a tool to help in interrogation, etc. So, if you "fool" the polygraph, then you can chalk it up as a small victory in a sense.

If its for a job, and the employer still suspects something is a foul. (The taking of drugs or alcohol to calm yourself and beat the system), then you can still lose out on the job over a hunch.

There isn't a polygraph tech out there that's worth his salt, that wont be able to pick up on anomolies (drugs, drink, etc), so even though you can "beat" the machine technically... there's still the human element and other factors you have to get past.

Yes

Back in 1985, I applied for a job at a retail store which required all applicants to take a lie detector test. One question: Have you ever stolen anything? I said NO. The truth was YES.

And I got the job. But no I didn't steal anything. I had stolen something when I was about 7. I was 30 when I applied for this job.

Yes.
The machine measures several of your bodies natural responses to stress. If you suddenly becomes stressed while answering a question, that will be marked as a lie. If you believe you are telling the truth, the machine wont "know" you are lying. Also, if you are a compulsive liar, you tend to have the same response to lying as someone who doesn't know they're lying.

you do no longer in all possibility "fool" them, yet you could land up with an inconclusive try. I doubt it particularly is ever something intentional. The polygraph detects variations interior the physique precipitated by using the stress of mendacity. in case you have no longer have been given a ethical experience, or in case you do no longer understand suitable from incorrect, your physique won't pass by using any measurable substitute for the time of a lie. for a typical guy or woman, i could think of the greater you tried to lie, the greater substitute your physique could pass by using.

Yup, but the govts are coming out with a much more advance technology which is much more harder to fool, the technology is still under development.

Yes, pathological liars pass them all the time, because they believe their lies are the truth, and display no signs of deception, or lying.This is why polygraph exam results are NOT admissable in court.

Yes. You see it is all reallistically based on your blood pressure and heart beat. If you stay calm and all, then the test will say you're telling the truth.

Yes they can also give false positive readings. That is why they are inadmissable as evidence.
