So, one of the most important concepts in analyzing human behavior is that of the baseline. So, everybody essentially has a normal or extended behavior on how they act. So certain people will sit in their chairs a certain way or certain people will, you know, have a conversation a certain way. And this is what happens, you're looking for slight deviations in this behavior. And there's examples of this throughout the broad spectrum of communication. So, for example, um, like, if, if somebody calls you every single day and then all of a sudden, they don't call you for three days, that tends to mean something cause it's a deviation in baseline. So, it's the same thing in numeral actions. For example, like the girl who touches everybody usually won't touch the person she likes. And the girl who never touches anybody will usually touch the person she likes. So essentially what you're, what you're looking for are these deviations in baseline behaviors. And it can be very, very, um, provides you with a ton of information essentially. Because we're, we're just, once we find the deviation, we may not be sure of why they deviated but we know it means something and we need to pay attention to it and it's one of the most useful things you can do. And there's deviations in every single non kind of nonverbal behavior. So, for example, let's say you were giving a presentation and the person walked in the room and he kept moving his leg, bouncing his leg up and down. Bouncing his leg up and down. And then all of a sudden, when you talk about a certain specific topic, his leg movement stops. He might be interested in that topic, so it's a deviation baseline. And you're just, you're constantly looking for these.
