The first dead giveaway to tell when someone is lying is to look at their physical stature or body language. When the someone is lying, often times their body will be stiff. Also hand and arm movements will be limited and both will be drawn in towards the body as if they're protecting themselves from something.
Also when someone is lying eye contact will be minimal. Other physical signs of lying is unnecessary touching of the face, throat and mouth. One may also be found scratching their nose or behind the ears.
Contradicting Emotional Gestures
When watching someone's emotional gestures note the timing between the actual gesture and the words coming from their mouth. If someone were to say "I really like it" and then smile afterwards instead a smiling at the same time, this may be a sure sign of deception. Also gestures or expressions won't match their verbal statement, such as saying "I love going to your parent's house for dinner," while frowning.
When someone is lying their expressions and gestures are unnatural. Usually when someone smiles a whole group of facial muscle muscles are involved such as the jaw/cheeks, eyes and forehead, and nose. When someone is faking an emotion, usually only their mouth muscles will move.
Unconscious interaction
The guilty person is always on the defense and always defending themselves no matter what you say. A person who is telling the truth often goes on the offense stating relevant facts and information. If the person is lying they may be uncomfortable and turn their head and body away from you. They also may inadvertently or unconsciously place any objects they are holding between you and themselves as if to create a barrier.
Verbal interaction
A liar will use similar words or phrases that you've used in your question, to actually answer the question. For instance if you were to ask, "Were you out late last night?" The liar answers, "No, I wasn't out late last night." Another thing to note is that liars will often fully express conjunctions. For instance, a liar will say, "No I did not do it," rather than saying, "No, I didn't."
Often times a liar will speak very softly or muddle their words. Their sentences will be garbled instead of clearly stating what they mean.
Other techniques
If you think someone is lying, then change the subject of the conversation quickly. A liar will often times become more relaxed and want to change the topic as quickly as you do. If they are innocent, they will be confused by the sudden subject change and they will want to go back and address the previous conversation.
Another technique liars often used to avoid the subject is to use humor or sarcasm. If the person is often laughing and wants to make jokes about irrelevant topics, this can be a sign that they are lying.
One powerful strategy is to act as if you know already. Don't ask a person if they were out late last night, rather tell them you know they were out late last night then follow it up with the question: "So, why were you out late last night?" Often a liar will come clean if he thinks you already know they've committed the offense.
Final notes
Obviously it goes without saying that just because a person shows one or more of these signs of lying does not mean that they're doing so. Some people are naturally uncomfortable when being interrogated whether they are innocent are not. Whenever possible, you should compare the signs of lying to their normal interaction. Using some sense, and these proven tips you'll be able to catch a liar nine out of ten times.
