The psychology of deception is not just about lying with words, but about the complex internal mechanisms that allow us to deceive others, and most often ourselves. This is a branch of psychology that studies why we rationalize actions, distort memories, and build illusions in order to maintain a positive self-image.

Self-deception is not always a conscious decision, but rather a defense mechanism of the psyche that helps us avoid painful truths, guilt, or dissonance. Here we talk about how understanding these mechanisms can help us be more honest with ourselves and, as a result, with others.
