Mele's modified definition of self-deception is consistent with evolutionary theory. Self-deception is most likely whenever ignorance confers (reproductive) advantage, namely, in impression management, deception, conformity, social norms, reproductive knowledge, and existential conflicts. Second-order self-deception (unawareness of unawareness) perpetuates self-deception and may be the reason for our misguided definitions.

In this entry, I seek to show the interdependence of questions about self-deception in philosophy of mind, psychology, and ethics. I taxonomize solutions to the paradoxes of self-deception, present possible psychological mechanisms behind it, and highlight how different approaches to the philosophy of mind and psychology will affect how we answer important ethical questions. Is self-deception conducive to happiness? How does self-deception affect responsibility? Is there something intrinsically wrong with self-deception? The entry, on the one hand, is a tour of the literature; on the other, it is a case for more work that crosses traditional sub-disciplinary boundaries.

I raise the question of what cognitive attitude self-deception brings about. That is: what is the product of self-deception? Robert Audi and Georges Rey have argued that self-deception does not bring about belief in the usual sense, but rather “avowal” or “avowed belief.” That means a tendency to affirm verbally (both privately and publicly) that lacks normal belief-like connections to non-verbal actions. I contest their view by discussing cases in which the product of self-deception is implicated in action in a way that exemplifies the motivational role of belief. Furthermore, by applying independent criteria of what it is for a mental state to be a belief, I defend the more intuitive view that being self-deceived that p entails believing that p. Beliefs (i) are the default for action relative to other cognitive attitudes (such as imagining and hypothesis) and (ii) have cognitive governance over the other cognitive attitudes. I explicate these two relations and argue that they obtain for the product of self-deception.

This response addresses seven main issues: (1) alleged evidence that in some instances of self-deception an individual simultaneously possesses “contradictory beliefs”; (2) whether garden-variety self-deception is intentional; (3) whether conditions that I claimed to be conceptually sufficient for self-deception are so; (4) significant similarities and differences between self-deception and interpersonal deception; (5) how instances of self-deception are to be explained, and the roles of motivation in explaining them; (6) differences among various kinds of self- deception; (7) whether a proper conception of self-deception implies that definitive ascriptions of self-deception to individuals are impossible.

This essay is a plea for the view that philosophers should analyze the concept of self-deception more with the aim of having useful applications for empirical research. This is especially desirable because psychologists often use different, even incompat-ible conceptions of self-deception when investigating the factual conditions and con-sequences, as well as the very existence, of the phenomenon. At the same time, philosophers who exploit psychological research on human cognition and reasoning in order to better understand self-deception fail to realize that these theories and data are loaded with problematic assumptions. More specifically, I discuss what conceptions of rationality are assumed when we describe cases of self-deception as either irra-tional or as adaptively rational, and how competing ontological models of the self ap-pear in different accounts of self-deception. I argue, first, that although the self typically is an object of such deception, it is not always so. Secondly, while it is the subject of deception, it is so only in a moderate way: We need neither assume multi-ple selves, nor is self-deception typically brought about or sustained intentionally. However, the avoidance of self-deception is at least sometimes under the subject’s ra-tional control. This account does not take for granted the existence of the phenomenon of self-deception. It is a serious task of empirical research to figure out whether self-deception really occurs. This issue also depends on the question ignored until now of what normative conception of rationality is assumed when one views certain beliefs as self-deceptive.

Mele's study of philosophical and psychological theories of self-deception informatively links the conceptual and dynamic aspects of self-deception and explicates it without positing mutually inconsistent beliefs, such as those occurring in two-person deception. It is argued, however, that he does not do full justice to the dissociation characteristic of self-deception and does not sufficiently distinguish self-deception from self-caused deception.

I argue here that self-deception is not conducive to happiness. There is a long train of thought in social psychology that seems to say that it is, but proper understanding of the data does not yield this conclusion. Illusion must be distinguished from mere imagining. Self-deception must be distinguished from self-inflation bias and from self-fulfilling belief. Once these distinctions are in place, the case for self-deception falls apart. Furthermore, by yielding false beliefs, self-deception undermines desire satisfaction. Finally, I argue for the positive view that *honest imagining* can yield the psychological benefits that others have claimed for self-deception.

The essence of a mental event such as self-deception lies in its function – its place in the life of an animal. But the function of self-deception corresponds to that of interpersonal deception. Therefore self-deception, contrary to Mele's thesis, is essentially isomorphic with interpersonal deception.

Everyone, with the possible exception of those who are really good at it, is personally familiar with the phenomenon of self-deception. Anyone who has been conscious of struggling with a temptation to do what goes against her own better judgment and has then found justification for yielding to temptation is familiar with self-deception. So if I may be allowed to begin with the assumption that most of us have experienced a phenomenon that we would identify as some form of self-deception, what I shall try to do in this paper is to examine how one particular theory of personal identity can account for the phenomenon. Having done that, I shall look into the question of one of the mechanisms of self-deception and then into the question of whether there are occasions in which the mechanisms of self-deception may be regarded as producing more positive results.

I raise three puzzles concerning self-deception: (i) a conceptual paradox, (ii) a dilemma about how to understand human cognitive evolution, and (iii) a tension between the fact of self-deception and Davidson’s interpretive view. I advance solutions to the first two and lay a groundwork for addressing the third. The capacity for self-deception, I argue, is a spandrel, in Gould’s and Lewontin’s sense, of other mental traits, i.e., a structural byproduct. The irony is that the mental traits of which self-deception is a spandrel/byproduct are themselves rational.
