Deception is an inherent part of human interaction, woven into the fabric of communication, relationships, and society. It takes many forms, from outright lies to subtle misdirections, half-truths, and omissions. While deception is often associated with negative consequences, it is not always malicious. In some cases, it is used to protect feelings, maintain social harmony, or navigate complex situations. However, the fundamental nature of deception remains the same—it involves misleading others, either intentionally or through omission, to influence perception or behavior.

At its core, deception exploits the gap between reality and perception. When someone is deceived, their understanding of a situation is altered, often leading them to make decisions based on false or incomplete information. This can happen in personal relationships, business dealings, politics, and even within an individual's own mind. Deception is not limited to spoken or written words; it can also be conveyed through body language, selective sharing of information, or strategic silence.

One of the key reasons people deceive is self-preservation. Whether to avoid punishment, escape embarrassment, or gain an advantage, deception often serves as a tool for personal protection. From childhood, individuals learn that certain truths may have negative consequences, leading them to develop ways to manipulate the truth. Over time, this can evolve into more sophisticated forms of deception, ranging from small white lies to elaborate schemes designed to control or mislead others.
