Self-deception


Self-deception is a process of denying or rationalizing away the relevance, significance, or importance of opposing evidence and logical argument. Self-deception involves convincing oneself of a truth (or lack of truth) so that one does not reveal any self-knowledge of the deception.

The traditional paradigm of self-deception is modeled after interpersonal deception, where A intentionally gets B to believe some proposition p, all the while knowing or believing truly ¬p (not p). Such deception is intentional and requires the deceiver to know or believe ¬p and the deceived to believe p. On this traditional mode, self-deceivers must (1) hold contradictory beliefs and (2) intentionally get themselves to hold a belief they know or believe truly to be false.

The process of rationalization, however, can obscure the intent of self-deception. Brian McLaughlin illustrates that such rationalizations in certain circumstances permit the phenomenon. When a person, who disbelieves p, intentionally tries to make himself believe or continue believing p by engaging in such activities, and, as a result unintentionally misleads himself into believing or continuing to believe p via biased thinking, he deceives himself in a way appropriate for self-deception. No deceitful intention is required for this.

Self-deception calls into question the nature of the individual, specifically in a psychological context and the nature of "self". Irrationality is the foundation upon which the argued paradoxes of self-deception stem, and it is argued[weasel word] that not everyone has the "special talents" and capacities for self-deception. However, rationalization is influenced by a myriad of factors, including socialization, personal biases, fear, and cognitive repression. Such rationalization can be manipulated in both positive and negative fashions; convincing one to perceive a negative situation optimistically and vice versa. In contrast, rationalization alone cannot effectively clarify the dynamics of self-deception, as reason is just one adaptive form mental processes can take.

The works of philosopher Alfred R. Mele have provided insight into some of the more prominent paradoxes regarding self-deception. Two of these paradoxes include the self-deceiver's state of mind and the dynamics of self-deception, coined the "static" paradox and the "dynamic/strategic" paradox, respectively.
