Deception

Deception is the intentional act of causing someone to believe something false or misleading, through words, actions, omissions, or fabricated evidence.

Lying: Lying is making a statement the speaker believes to be false with the intention to mislead. A direct verbal tactic that creates a false belief through an assertion.
Belief: Belief is an attitude of accepting a proposition as true. Deception aims to produce or preserve a belief in its target.
Honesty: Honesty is the practice of communicating and acting without intent to mislead. It opposes deception's deliberate effort to shape a false impression.
Mimicry: Mimicry is an evolved resemblance that influences how another organism responds to an organism or object. Some mimicry deceives predators or prey by exploiting their recognition cues.
Gaslighting: Gaslighting is a pattern of manipulation that makes someone doubt their memory, perception, or judgment. It shows how sustained deception can undermine a person's confidence in their own understanding.
Omission: An omission is the deliberate leaving out of relevant information. Withholding a decisive fact can mislead without stating anything false.
Intention: An intention is a mental commitment to bring about an action or outcome. The deceiver's aim to mislead distinguishes deception from accidental error.
Self-deception: Self-deception is the process of maintaining or adopting a false belief about oneself or reality. Unlike ordinary deception, its target and deceiver may be the same person.
Counterintelligence: Counterintelligence is the activity of protecting an organization from espionage and hostile intelligence operations. It detects, frustrates, or redirects deceptive operations by adversaries.
Fraud: Fraud is intentional deception used to secure an unlawful or unfair gain. It is a legally consequential form of deception tied to gain or harm.
