Reliable information is crucial to making a good decision. Learn how to separate the truth from the lies, and you will go a long way in protecting yourself from fraud, or being taken for a ride. Wikihow has a great post about how to tell if someone is lying, and here some of the key tips from that article.

• Look at the mouth, and see if you can see the teeth. A forced smile will not reveal teeth.
• A typical right-handed person tends to look towards his right when remembering something that actually happened and towards their left when they’re making something up.
• Liars also tend to blink more often, sweat more, and are not likely to touch their chest or heart with an open hand.
• They become uncomfortable and restless the person becomes when there is a pause.
• Liars speak in a defensive manner (they will be relieved if you change the subject).

Please note that just because a person acts this way, it does not make him a liar. The above actions are generalizations and should just be regarded as rough indicators of how people act.
