The Polygraph Test

The polygraph test is utilized by Police recruiters to determine if applicants have been truth during the application process.

The polygraph test is also sometimes referred to as a "lie detector test." That is inaccurate.

It does not measure whether or not someone is lying. It measures changes in a person's physiological response to certain questions. The changes include:

- pulse - breathing

- blood pressure

- body temperature

- galvanic skin response (sweat/salt on skin) The belief is that "lying" when asked a question will elicit one or more of the above changes.

So, the machine detects the changes, not the telling of a "lie".

You'll know before hand when the test is going to be.

You'll be told to get some rest before and to not drink anything with caffeine. Also to make sure that you're not sick on the day of the test.

On the day of the test you'll be told to fill out a questionnaire. There will be about 100 questions, give or take.

These are designed to stimulate past memories and experiences.

Then you'll be hooked up to the machine. They'll ask you some control questions, then about 10 real questions. The test itself isn't long at all.

They'll leave, you sit there sweating. They'll return and grill you about something to see what you say. Then, that's it.

If you were honest in answering the questions, they'll know it. If you weren't they'll know that too.

I can't predict exactly what questions they will ask you. And even if I could, I wouldn't tell you that on this website.

I'm just trying to inform people of some of the steps you'll have to take.

I'm not trying to help anyone circumvent the process.
