Answer 5

i don't believe those are very accurate because it proves you are lying when you get nervous on a question. but, you may be telling the truth and were just nervouse because you were taking it.

Answer 6

when my husband and i were moving out of state, my ex accused me of child abuse so he could get custody of our son.  I took a lie detector test to prove my innocense.  

The one i took was based on voice.  It recorded the pitches and such in my voice.  I passed of course and yeah i was nervous but you could defanately tell the ones i lied on.  

They ask you a series of questions and they have a few questions that they want you to lie on so they can see what you're lies look like.  Most of the questions are basic and then they randomly throw the important ones in there:

Is the color of the wall brown?

Have you ever driven over the speed limit?

Did you put the marks on Dakota's bottom?

Is your name Candace?

Are you married?

Do you know where the marks on Dakota's bottom came from?

Is the door closed?

And that's pretty much it.  If you're lying, you should worry, they're pretty accurate.  But if not, not a biggie, it's a good way to clear your name.
