Theoretical debates around the concept of self-deception revolve around identifying the conditions for a behavior to qualify as self-deception. Experiments 1 and 2 revealed that various candidate features—such as intent, belief change, and motive—are treated as sufficient, but non-necessary, conditions according to the lay concept of self-deception. This led us to ask whether there are multiple lay concepts, such that different participants endorse competing theories (the disagreement view), or whether individual participants assign partial weight to various features and consequently waver (...) in cases of middling similarity (the conflict view). In Experiment 3, by-participant regression models uncovered that most participants additively consider multiple characteristics of the prototype of self-deception, while only a minority of participants treat a characteristic (or a combination thereof) as necessary and sufficient. In sum, by disambiguating interpersonal disagreement and intrapersonal conflict in a within-subjects design, the present experiments indicate that the lay concept may primarily exhibit a prototype structure. In closing, we suggest that future research deploying this method may help to explain why experimental research on philosophical concepts often engenders partial support for competing theories.

Selbsttäuschung scheint ein alltägliches Phänomen zu sein. Wir nehmen an Anderen wahr, wie sie mehr oder weniger bewusst einer Einsicht ausweichen, die sie nicht wahrhaben wollen, und die meisten von uns können sich an Situationen erinnern, in denen sie sich selbst etwas vorgemacht haben. Wir können also Beispiele für Selbsttäuschung benennen, unser begriffliches Verständnis von Selbsttäuschung aber ist diffus, und der Versuch, das Phänomen aus philosophischer Perspektive begrifflich genau zu fassen, führt leicht zu starken Spannungen, für die bis heute keine (...) allgemein akzeptierte Lösung gefunden wurde. Auch die Frage, wie Selbsttäuschung prudentiell und moralisch zu bewerten ist, ist kontrovers. (shrink)

The folk explanation of self-deception is that one mental subsystem deceives another. Deflationists appeal to motivated irrationality rather than deceptive subsystems to offer nifty accounts of many sorts of self-deception. However, I shall show that deflationists cannot explain the self-deception embedded within (1) impulsive, (2) vacillating, or (3) long-term akrasia. These akratic actions are respectively too short, too variable, or too long for motivated irrationality to do its dirty work. Nor can deflationists explain the self-deception required for motivating oneself to (...) (4) suspend disbelief and lose oneself in fiction, (5) bother to make negligible contributions to very large projects, (6) accomplish daunting tasks by taking them one day at a time, or (7) cope with psychologically traumatic truths. In these four cases, the truth is undeniable, yet agents must also hold contravening false beliefs. Thus, the folk explanation of self-deception is preferable, despite its invocation of deceptive mental subsystems. (shrink)

The paper analyzes the two types of self-deception, usually labeled straight and twisted self-deception. In straight cases the self-deceptive belief coincides with the subject’s desire. In twisted cases, by contrast, the self-deceptive belief opposes the subject’s desire as in the example of Othello’s conviction of Desdemona’s infidelity. Are both these contrasting types of deceptive beliefs cases of SD? The argument of this paper shall answer this question in the positive, yet in different way from the unitary explanation of straight and (...) twisted SD proposed by Alfred Mele. The causal account of SD claims to provide a unitary and simple explanation for both straight and twisted SD, and considers such a unitary explanation as a specific virtue of the causal view. Within the same causal model, the difference between straight and twisted self-deception is explained by a difference in the motivational state that in twisted cases is dominated by emotions. The paper will critically examine this claim, and advance an alternative explanation based on a different view of self-deception where emotions play a role alongside wishes both in straight and in twisted case.

In this paper I argue against three leading accounts of self-deception in the philosophical literature and propose a heretofore overlooked route to self-deception. The central problem with extant accounts of self-deception is that they are unable to balance two crucial desiderata: (1) to make the dynamics of self-deception (e.g., the formation of self-deceptive beliefs) psychologically plausible and (2) to capture self-deception as an intentional phenomenon for which the self-deceiver is responsible. I argue that the three leading views all fail on (...) one or both counts. However, I claim that many or most cases of self-deception conform to a different model, which I call ‘Self-deception as Omission’. In these cases, the process of self-deceptive belief formation and the intentional act for which the self-deceiver is responsible come apart, allowing us to meet both desiderata. Self-deceptive beliefs are often formed by unconscious mechanisms closely analogous to the 'System 1' processes of dual-systems psychology, or by other mechanisms of motivated reasoning. The nascently self-deceptive subject then acquiesces in the comforting belief and commits an epistemic failure by allowing it to persist. If this is done for motivationally biased reasons — e.g., preferring that the belief in question be true — then the subject is self-deceived and is blameworthy for her epistemic omission. (shrink)
