Is it possible to lie without saying a word?

Yes, simply being silent about something is the same as blurting out a huge whopper!

Sure. One can be guilty of lying by omission.

Read: What @ZEPHYRA said just before me. I type too slowly.

You can answer Yes/No questions falsely with gestures. You can shrug as if you do not know the answer when in fact you do. You can withhold the truth when it is required.

True you can lie by omission but that depends on if you know the whole truth. Lets say someone said that they suspected there husband of cheating with a particular person. I’m under no obligation to say anything one way or the other. If they wanted to know they wouldn’t make it a statement they would ask. And if they name the wrong person than I’m not lying if they ask me if I thought said person was having an affair with that particular person, if I knew they were having an affair with someone else. Plus I wouldn’t think it lying but rather staying out of something that is not my business.

A lie of omission is to remain silent when ethical behavior calls for one to speak up. A lie of omission is a method of deception and duplicity that uses the technique of simply remaining silent when speaking the truth would significantly alter the other person’s capacity to make an informed decision.

A lie is not in the words, or lack of words; it’s in the intention of the deceiver.

Some words of wisdom from those cleverer than us:

“This above all: to thine own self be true”. – Hamlet (Act I, Scene III).

The visionary lies to himself, the liar only to others.
Friedrich Nietzsche

All men are frauds. The only difference between them is that some admit it.
I myself deny it.

H. L. Mencken

A lie told often enough becomes the truth.

Any fool can tell the truth, but it requires a man of some sense to know how to lie well.

Absolutely. When given the choice between the two, most people will believe what you do, not what you say.

The push up bra. Need I say more?

Absolutely. Furthermore, you can lie when you’re telling the truth if you’re unaware your “truth” is a lie due to misinformation or blind belief.

Nods head.

@Artistree, good thing I wasn’t drinking anything when I read this, else my monitor would be soaked!

If you have knowledge of something and are directly asked about it then by remaining silent you can be lying. Guilty until proven innocent doesn’t really fly even though it’s American court law.

Yes, silence is generally accepted as an answer to a question.
