How Can I Tell If Someone is Lying to Me?

How Can I Tell If Someone is Lying to Me?I'm going to put a poll up right now and ask you guys to help me out with a problem I'm having in my life and I'm trying to figure out how to tell if someone is lying or not. It's something about 'how can I tell if someone is lying to me' and that is what this poll is all about.Why do people lie? Is it their power, ego, confidence or just the way they want to be perceived? Or does lying just simply happen like it or maybe is it something that we learn and understand?Well as it happens there is only one way to find out but you need to help me out and tell me how. So the question is this: why do some people try to avoid situations that expose them to criticism. How is it that other people are able to live so much of their lives around people that try to criticize them?Did you know that some alpha males are afraid to walk down the street without their jacket on. Well that is because they know that the people will ridicule them for being too weak to protect themselves. I am not saying that everyone in your life has to have a secret life or to hide who they really are but you have to learn to deal with people who try to avoid criticism.Why is it that some people would rather accept the blame for something when they should not accept it? I guess that just happens to be their nature. They do not want to be criticized and then they get upset and lash out at people when they say or do something that is wrong.So, how can I tell if someone is lying or not? Well, you can look at them and see if they are. You could also look at what they are doing when they are doing it but this is so confusing that it would be easier if you had some kind of outside help.That is why I am asking you guys to take a survey about your topic so that I can make my topic easier to read and write about. If you think you could help me out that would be great and I would love to hear from you. I hope you can handle the time involved in doing this survey.I suck at linear algebra, please help me out. I promise I will give you better answers.
