Polygraphs are complete bullshit, but the "theory" is pretty simple.

There will be a pre-test interview with the objective of finding some topics that they don't really care about but will make you feel very nervous, guilty, worried, over-thinking, etc.

Then in the actual test, they'll randomly ask you about things they do care about and things that they've tried to find/make very stressful for you with the pre-test interview.

The questions about the stress topics are establish a "control" lie/deception response. And then they compare your response to "relevant" questions with the "control". 

So respond stressfully (puckering one's asshole is apparently an effective technique) to "control" questions, and normally to everything else.

And again, your "control" questions will probably be obvious from the pre-test interview, but are most likely to be about sex, drugs, or crime -- and especially, regarding stuff in the past as opposed to now. For example, questions along the lines of "have you ever done x?", as opposed to "do you currently do x?", are much more likely to be "control" questions.

When there are specific questions asked that could either make or break you, for example, arson, bestiality, etc. When I am asked these questions, even though I know I should be safe, I want to ensure that I will pass the examination.

I"m unsure what you mean.

Hello B-man,

The obvious tip is; when you make a fire you're supposed to cook the beast
and then eat it. Not the other way around.

Hello all,

I will be having an upcoming polygraph test in the near future, and I know it is policing I want to have a career in.  Everything involving the selection process does not want to turn me away but the polygraph procedure. I know I have done some things, but like they say, no one is perfect. 

When there are specific questions asked that could either make or break you, for example, arson, bestiality, etc. When I am asked these questions, even though I know I should be safe, I want to ensure that I will pass the examination.

If anyone has any tips and advice, I would greatly appreciate it.

Cheers,
