Disclaimer: I don’t recommend lying. It’s wrong and it’s risky. You’ll feel bad about it, depending on how much of a conscience you have, and the more you do it, the greater the chance someone’s going to catch you. That being said, if you’re going to lie… do it well.
A great way to reduce the amount of nonverbals that tell people you’re lying is to simply fake a headache. It’s so simple and easy, and incredibly effective.
When you’re lying, your voice changes, your facial expressions give you away, and even the types of words you use will change. The best way I know of to completely eliminate this and lie effectively is to literally believe your own lie, which I have written about.
Well some people can’t do that very well. Or you don’t have time to mentally prepare for it.
Fake a headache.
First of all, nobody will ever, ever doubt that you have a headache. It’s in your own head, and there’s no way to prove you wrong. Even if you are constantly doing this because you’re a compulsive liar, people will just think you get a lot of headaches. It’s absolutely subjective and not subject to suspicion. Headaches can come out of nowhere.
What a headache does for you:
When you are visibly in a small-to-moderate amount of pain, your voice will change a bit, your facial expressions will change, basically everything that someone would have picked up that might indicate you’re lying — your “tells,” so to speak — is masked by the fact that your head hurts. Nobody will be able to tell the difference.
You’re intentionally altering your voice in a socially acceptable way, and nobody will pick up on the fact that you’re lying. Well, not from your body language, anyway.
