There are a lot reasons why you might want to start to learn if someone’s lying to you or not, and the people that have the most at stake are FBI agents, and one of their favorite and most relied upon tools is to notice if people go from still, like typically like a still body language, to fidgeting a lot, right, fidgeting, or if they go from fidgeting a lot to still. Okay. A lot of times when they do this is when the subject will change.
So if they’re talking about their family, right, and maybe how they got married or what their dog did last night because they’ll always try to engage the perpetrator in this manner to get them to be comfortable and then they talk about the crime or certain people that they’re associated with. Then they may see their body language change dramatically because most of the time people communicate in very similar ways, whether they talk with their hands a lot or they’re very still. It’s hard for me to do, but if I started lying I might be very still all of sudden. But I’m telling the truth right now. So watch for that.
Also start to notice when people go from convincing or switch between convincing and conveying. Most times we convey information, but if I’m really trying to get you to believe something my body language may shift and I may go into more of a convincing type tone and I may go into a few too many details for what’s necessary to get the information across.
So again, you want to normalize what people do. Start to understand that their baseline behavior, and when they shift from that, you have a good idea that what’s going on across from you isn’t true.
