Let’s face it, we have all probably lied or stretched the truth at some point in our lives, but there are people around who lie all the time and this can prove to become a trust issue in time. Yet, unless you have actually caught them out lying through their teeth, how would you know who is a liar and who is telling the truth. Well, thanks to this graphic found on PiTribe that should be easier than you think. Apparently, we all give away signs that we are lying, this is how professionals know that people are lying when they are questioned about something. Clearly this is not an exact science, but it will give you a better understanding of where you stand, this is especially handy for employers etc.
