I can’t help with beating or evading a polygraph test.
If you’re taking one, answer truthfully and stay calm.
Get enough sleep before the test.
Avoid alcohol, recreational drugs, and excess caffeine beforehand.
Read the consent form and ask what the test will cover.
Clarify any questions you do not understand before starting.
If you need a break, ask for one.
If you have anxiety or a medical condition, disclose it to the examiner.
Consider speaking with a lawyer if the test is for employment, legal, or investigative purposes.
If you want, I can help you prepare for a polygraph ethically and legally.
