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.
If you believe what you are saying is actually true, your lie will be more convincing. You truly have to believe it in the core of your mind. You need to invent an event in your past. Accept that event as the actual, literal truth. Your body language will tell the other person that you’re being truthful.
Whatever you do, the absolute worst thing that you can do is think about the fact that you’re telling a lie while you’re lying. The spell is broken, and you’ll sound nervous, or different than usual, or something. They’ll notice, if they’re perceptive.
The most important facet of deceiving someone is convincing them to believe what you’re saying is true. Obviously that’s the point. If not, I don’t really understand what it is that you’re doing.
Anyone who’s read a book or watched a movie knows that the way to tell if someone is lying to you is by looking at their body language. People can just generally sense when someone is lying sometimes, even if they don’t know why. They’re reading that body language.
Which body language? That’s a post all in itself that I will write based on a large body of research.
But it really doesn’t matter.
The best advice I can give for “How to Lie” is to literally believe your own lie. I wrote a paper about this in my 7th grade English class, and was awarded the unusual combination of a 100% grade and a frown face.
I was in high school, and I absolutely did not do my math homework. So, invent a reason why, but actually believe that reason. The more emotionally loaded the reason, the better (depending on how unethical you’re willing to be). Before class, before any of the other students arrived, I told my teacher that I was going through a lot of family problems with my mother and step-father arguing, and I would like another day to work on the homework.
Was I having family problems? Probably no more than normal, but it doesn’t matter. Before I went in to tell him, I vividly envisioned my mother and step-father fighting, screaming at each other, throwing things, and me standing in the distance watching them, feeling sad.
That sadness is key. Let the emotions of the [imaginary] situation wash over you. That emotion is so important.
When you tell your lie, you’ll be experiencing actual human emotion. And that emotion will register to the other person as valid, because you actually are feeling sad.
Just like you can feel sad, happy, or fearful from watching a movie or reading a book, this is the exact same thing. When you discuss a Harry Potter novel with someone (I don’t read much fiction), you aren’t lying when you say Harry did this or that.
You need to invent an event in your past. Accept that event as the actual, literal truth. That is what happened. Your homework is on your desk. Imagine it being there, completed. Think about what you wrote the paper about.
Even if there is no paper at all.
Imagine yourself trying over and over to put your USB drive into the University computer lab terminal to print it off, only to find that the file isn’t being read. You tried and tried, but it isn’t working. There’s now nothing you can do except go home later, get the original file from your computer, and email it to your professor.
Your professor will understand, because it’s a plausible thing that can happen, and your body language is showing that you’re telling the truth. You’re telling a truth that you invented, but it doesn’t feel like you’re lying.
Believe that your own lie is the truth.
