And lying is, I mean, you get anxiety when you lie, if you are an honest person, at least.

So what we did is that we presented them with some tasks, some mathematical tasks, and we said like, okay, solve them.

And then when you solve them, after solving them, we will ask you how you think you performed.

And so they could say like, I think I performed well, I think I performed bad.

After that, we said, okay, now we're gonna tell you how you actually performed.

And we presented them with a random score, so it was not really true.

So we were the first one to lie.

And after that, we asked them to convince an expert in lie detection, which was, of course, not an expert in lie detection.

So we asked them to convince this expert, like, have you seen Lie to Me, the TV show?

There's an expert in light detection.

So we presented this researcher as an expert and we told the participants like, okay, now you have to convince them, whatever the actual score is, that you performed among the best.

So they had to perform.

At that point, they had to perform.

So we had like, maybe they received an actual positive score.

So it was the truth, no?

You say, okay, you did good.

Now tell me you did good.

And you say, well, yeah, I did good.

So that's a true answer.

Or maybe I told you, you did bad, you did really bad.
