Thank you, David.

I'm very happy to be here.

So, you know, sometimes we don't really like the truth around us.

So sometimes we may decide to tell something to ourselves just to feel better about the actual truth.

Sometimes, you know, the truth is hard.

And so we try to deceive ourselves first.

And then maybe we also use these as a means to present ourselves in a more positive way to others.

So it's not really about the fact that we align to others, but first we align to ourselves so that we may be more convincing somehow.

Yeah.

And that's because, you know, they always speak about the use of polygraph in court.

And we always ask ourselves, why don't we use that?

And the reason is because our body actually responds to lying because it's stressful, you know, so you start sweating, actual sweating.

And that's what we did.

We recorded the people sweating.

So not as you can imagine, like heavy sweating.

But we have some sensors that we can put on people's hands and they are able to capture some micro sweating.

And the thing is, everything can be a source of anxiety, no?

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.
