Essentially, a classic “lie detector” can just show whether the person it’s hooked up to is nervous. If there’s a variation in the detected “nervousness” that appears to correlate with questions being asked, then it was assumed that “nervous” meant “guilt”.
In some cases, that might actually be true, but there are many individuals who can lie without feeling “guilty” or “nervous”. So one thing such a “detector” can be “wrong” about is indicating that someone is “not lying”. And simply believing that it doesn’t work may be enough to stop the body from indicating “worry”, and thus prevent it from “working”. But it’s also possible that a person can become “nervous” due to the simple fact of being hooked up to such a machine.

If I remember correctly, lie detector machines are mostly useless in detecting lies.

If you can convince yourself you’re not lying, it would work.
