Truth is a term used to indicate various forms of fact or reality, or fidelity to a standard or ideal. The opposite of truth is falsehood, which, correspondingly, can also take on logical, factual, or ethical meanings. Language and words are a means by which humans convey information to one another in semiotic associations, and the method used to recognize a truth is termed a criterion of truth.

Criteria of truth (or tests of truth) are standards and rules used to judge the accuracy of statements and claims. Self-verification is a social psychological theory that asserts people want to be known and understood by others according to their firmly held beliefs and feelings about themselves. The question is, how much truth stands as a witness to what you are told and how can you know.
