Are you going to be taking a polygraph examination soon? Here are 11 tips to help improve its accuracy:

How To Increase The Accuracy of Your Polygraph Examination

1. Have a full night of sleep the night before.

2. Have no alcohol or unprescribed drugs in your system.

3. Do not arrive late or rushed for your exam.

4. No gum-chewing.

5. Answer Yes or No with your mouth only (do not nod or move your head when answering)

6. Remain still during the entire examination; no moving of hands, feet, neck, or anything other than your mouth.

7. Don't answer any questions louder or stronger than the others.

8. Sit in a position that will remain comfortable for a few 5-minute chart-collections.

9. No deep-breaths during the chart collection; breathe the same on all questions.

10. Insist that all testing be done on a modern computer polygraph (not on an old-fashioned antique 'roll of chart paper with 4 moving ink pens').

11. Drink plenty of water in the hours just before the testing.
