FAQ
Frequently Asked Questions
Not always. While often associated with illegal fraud, deception can exist in non-criminal contexts (e.g., magic tricks, tactical deception in games, or some forms of bluffing), though it remains ethically questionable.
A lie is a specific false statement. Deception is a broader concept—it is the successful act of causing someone to believe a falsehood, which can be achieved through lies, omissions, illusions, or actions.
Typically, no. The core meaning of 'deception' implies a deliberate intent to mislead. If there is no intent, words like 'misunderstanding' or 'mistake' are more appropriate.
Self-deception is the psychological process of denying or rationalizing away the relevance, significance, or importance of opposing evidence and logical argument to convince oneself of a belief that is false.
