lies

Lies are statements presented as facts that the speaker knows are false or deliberately intends to mislead. When a false statement is made without such intent, it is generally considered a mistake or misinformation rather than a lie.

Common types include lies of commission (deliberate false statements), lies of omission (withholding material information), exaggerations, fabrications, and misdirection. Some lies are small or socially tolerated (“white lies”) while others are designed to cause harm or gain.

Motives vary: personal gain, avoidance of punishment, protection of others, shaping opinion, or manipulating social norms. Lies can be self-serving or serve collective interests in ambiguous ways. Lies can be habitual or situational.

Consequences include erosion of trust, damaged relationships, and harm to institutions when lies spread across media, government, or business. Detection relies on corroboration, motive assessment, and evidence; formal lie detectors (polygraphs) have limited reliability and are not universally admissible.

Ethics and law: many philosophical and religious traditions condemn lying as immoral, though some permit it under certain circumstances (for example, to prevent greater harm). Legally, false statements can amount to defamation, fraud, or perjury; social norms deter lying to maintain credibility and accountability. Lies differ across cultures and historical periods in what is considered acceptable.
