Look out for these three signs that you're being lied to:
1. Discomfort. People who lie often demonstrate visible anxiety. This may be because they're afraid of getting caught or they feel guilty. Be on the look-out for a fake smile, frozen body language, or lack of eye contact.
2. Evasiveness. Someone who withholds information or keeps the conversation vague, or wants to discuss matters offline, may not be telling the truth.
3. Manipulation. When you ask a question, people lying may answer with more detail than necessary. They may also use overly explicit language for emphasis. Watch out for this kind of manipulation.
