Number two: Eye contact

Not looking people in the eye is another big sign to look for if you think that people are lying to you. The thing that you need to watch out for though is people who make sure that they look you in the eye because they are doing everything that they can to make you think you are not being lied to. On average people, make eye contact for about half of a conversation, sometimes more and sometimes less. If the person you are talking to doesn't make eye contact at all or their eyes drift off during the most important part of the conversation chances are they are lying to you. People will break off eye contact when they are giving you a reason for not being somewhere or are in the middle of their story, so they get nervous and look away.

Number three: Things don't sound right

If when people are talking to you and you notice that what they are telling you is not adding up that is another sign that they could be lying. The biggest thing to look for in this aspect is the fact that when people are telling you something there story just doesn't make sense or that they are making statements that contradict one another.

Number four: Body language

Body language is another give away, similar to eye contact. With body language, you are going to want to look for unusual types of body language because that will lean towards the fact that something is amiss. Some of the unusual body language to watch out for is excessive foot tapping, fidgeting with their hair or hands, or other signs that indicate that they are nervous or uncomfortable. Blushing or lack of color in the face can also indicate that a person is being untruthful.

Number five: Changing the subject

People who are lying will often try to change the subject through telling jokes about the situation or using some kind of sarcasm. They try to change the subject because they think that if they distract you, you will not pursue the story any longer. Other people will allow you to change the subject without asking once to go back to what you were talking about because they don't want the conversation focuses in that direction any longer. People who are telling the truth will often redirect the conversation back to the original subject if you change the subject, either on accident or on purpose. Something else that you might notice is that if you try going back to the original conversation or ask why they changed the subject the person who is lying will try avoiding answering the question.

Number six: Defensive

People who are not telling the truth often get overly defensive if you question what they are talking about. In some cases, they might even accuse you of lying or refuse to answer questions. All of this is done because you simply asked a question and they got upset because they have been lying and are trying to hide the truth from you. When people react overly defensive, it is because you have touched a nerve and they are afraid that they will be caught.
