Deceitfulness
Deceitfulness is a form of behavior in which a person knowingly distorts facts or withholds information to achieve certain goals or avoid undesirable consequences. It may be expressed verbally, when a person says something untrue, or through nonverbal actions, such as gestures, facial expressions, or overall behavior.
Deceitfulness may arise from various motives. For example, a person may lie out of fear of punishment, to conceal mistakes, or to hide dishonest actions. A person may also lie to attract attention from others, receive praise, or protect their self-esteem.
