When the subject is changed, hes in a better, more relaxed mood. The guilty wants the subject changed; the innocent always wants a further exchange of information.

He does not become indignant when falsely accused. While he is being accused the liar will remain fairly expressionless. The liar is more concerned with how he is going to respond than he is with the accusation itself.

He uses such phrases as To tell you the truth, To be perfectly honest, and Why would I lie to you?

He has an answer to your question down pat, such as giving precise detail to an event occurring two months ago.

He stalls by asking you to repeat the question or by answering your question with a question.

Where did you hear that? Could you be more specific? or even repeating your question back to you, at an attempt at sounding incredulous. For example, Did I sell you a puppy with a heart condition? Is that what youre asking me?

What hes saying sounds implausible, such as During the past ten years, I have never used a specific racial epithet.

He offers a preamble to his statement starting with I dont want you to think that Often thats exactly what he wants you to think. Whenever someone makes a point of telling you what theyre not doing, you can be sure its exactly what they are doing. Such as, Not to hurt your feelings, but

He implies through a form of denial. You hear, Hes having marital problems, but it has nothing to do with his wifes new job. Whats the first thing you ask? What does his wife do? Suddenly youre in the exact conversation that is supposed to have no bearing on the facts.

He uses humor or sarcasm to defuse your concerns, rather than responding seriously.

He offers you a better alternative to your request when he is unable to give you what you originally asked for. Before you accept someone at his word that he has something better to offer, first see whether he has what you originally asked for. If he doesnt, then you shouldnt believe him.

All of his facts relating to numbers are the same or multiples of one another. Watch out when facts, figures, and information have unusual similarities.

There is evidence of involuntary responses that are anxiety based. Anxiety causes many things. His breather may appear as a deep, audible inhaling in an attempt to control hisbreathing to calm himself. Swallowing becomes difficult; he may clear his throat. His ability to focus on something is often diminished, unable to pay attention to whats going on.

He uses an obvious fact to support a dubious action. For example, lets say that a guard is standing watch over a restricted area. Its his job to check IDs of those who enter. Im not sure you have authorization, he says to a man attempting access. Im not surprised, answered the man, only a few people are aware of my clearance level. My work here is not supposed to be known by everyone.

He casually tells you something that deserves more attention.

He exclaims his displeasure at the actions of another who has done something similar so that you will not suspect him. For instance, if he is trying to throw you off track of his embezzlement scheme, he may openly chastise another employee for borrowing some office supplies for personal use at home. Your impression is that he is moral person who objects to something as minor as stealing office supplies. Certainly he cannot be responsible for a large-scale embezzlement scheme.

He may casually tell you something that should deserve more attention. Oh by the way, Ive got to go out of town next weekend on business. If he doesnt usually travel for work on the weekends, then you would expect her to make a point of how unusual the trip is. Her downplaying the trip makes it suspicious. When something out of the ordinary happens and the person doesnt draw attention to it, it means that he is trying to draw attention away from it. Another tactic is running off a long list of items in the hope that one will remain unnoticed.

If he lies about one thing, everything he says is questionable.

His story is so wild that you almost dont believe it. But you do, because if he wanted to lie, you think that he would have come up with something more plausible.
