In this article we argue that self-deception evolved to facilitate interpersonal deception by allowing people to avoid the cues to conscious deception that might reveal deceptive intent. Self-deception has two additional advantages: It eliminates the costly cognitive load that is typically associated with deceiving, and it can minimize retribution if the deception is discovered. Beyond its role in specific acts of deception, self-deceptive self-enhancement also allows people to display more confidence than is warranted, which has a host of social advantages. (...) The question then arises of how the self can be both deceiver and deceived. We propose that this is achieved through dissociations of mental processes, including conscious versus unconscious memories, conscious versus unconscious attitudes, and automatic versus controlled processes. Given the variety of methods for deceiving others, it should come as no surprise that self-deception manifests itself in a number of different psychological processes, and we discuss various types of self-deception. We then discuss the interpersonal versus intrapersonal nature of self-deception before considering the levels of consciousness at which the self can be deceived. Finally, we contrast our evolutionary approach to self-deception with current theories and debates in psychology and consider some of the costs associated with self-deception. (shrink)

Commentators raised 10 major questions with regard to self-deception: Are dual representations necessary? Does self-deception serve intrapersonal goals? What forces shape self-deception? Are there cultural differences in self-deception? What is the self? Does self-deception have costs? How well do people detect deception? Are self-deceivers lying? Do cognitive processes account for seemingly motivational ones? And how is mental illness tied up with self-deception? We address these questions and conclude that none of them compel major modifications to our theory of self-deception, although (...) many commentators provided helpful suggestions and observations.

Von Hippel & Trivers (VH&T) interpret belief in God and belief in strong government as the outcome of an active process of self-deception on a worldwide scale. We propose, instead, that these beliefs might simply be a passive spin-off of efficient cognitive processes.

Von Hippel & Trivers reason that the potential benefits of successfully deceiving others provide a basis for the evolution of self-deception. However, as self-deceptive processes themselves provide considerable adaptive value to an individual, self-deception may have evolved as an end in itself, rather than as the means to an end of improving other-deception.

Von Hippel & Trivers (VH&T) propose that self-deception has evolved to facilitate the deception of others. However, they ignore the subjective moral costs of deception and the crucial issue of credibility in self-deceptive speech. A self-signaling interpretation can account for the ritualistic quality of some self-deceptive affirmations and for the often-noted gap between what self-deceivers say and what they truly believe.

Cultural variability in self-enhancement is far more pronounced than the authors suggest; the sum of the evidence does not show that East Asians self-enhance in different domains from Westerners. Incorporating this cultural variation suggests a different way of understanding the adaptiveness of self-enhancement: It is adaptive in contexts where positive self-feelings and confidence are valued over relationship harmony, but is maladaptive in contexts where relationship harmony is prioritized.

In this essay, we consider helicases, defined as enzymes that use the free energies of binding and hydrolysis of ATP to drive the unwinding of double‐stranded nucleic acids, and ask how they function within, and are “coupled” to, the macromolecular machines of gene expression. To illustrate the principles of the integration of helicases into such machines, we consider the macromolecular complexes that direct and control DNA replication and DNA‐dependent RNA transcription, and use these systems to illustrate how machines centered around (...) coupled polymerase–helicase systems can be regulated by small changes in the interactions of their functional components.

Humans have a complex and dynamic mating system, and there is evidence that our modern sexual preferences stem from evolutionary pressures. In the current paper we explore male use of a dual mating strategy: simultaneously pursuing both a long-term relationship (pair-bonding) as well as short-term, extra-pair copulations (variety-seeking). The primary constraint on such sexual pursuits is partner preferences, which can limit male behavior and hence cloud inferences about male preferences. The aim of this study was to investigate heterosexual male mating (...) preferences when largely unconstrained by female partner preferences. In service of this goal, female full-service sex workers (N = 6) were surveyed on the traits and behaviors of their male clients (N = 516) and iterative cluster analysis was used to identify male mating typologies. Two clusters emerged: clients seeking a pair-bonding experience and clients seeking a variety experience. Results also suggested that romantically committed men were more likely to seek a variety experience than a relationship experience. We conclude that men desire both pair-bonding and sexual variety, and that their preference for one might be predicted by fulfilment of the other. These findings have implications for relationships, providing insight into motivations for male infidelity. (shrink)

The Politica as a specific genre of academic reflection on civil life developed from the later sixteenth century and flourished until at least the mid-seventeenth century, especially at universities in the Holy Roman Empire and where their influence was felt, as in the Dutch Republic. Theologians, Philosophers, Jurists, and Medical Doctors contributed books. Aside from few and only with difficulty accessible surveys, and a few individual well-researched authors, research into this genre remains a task for the future. This survey collects (...) contributions from a number of senior and younger researchers and their various approaches and arguments. In particular, by providing examples of the heterogeneity of current research, it serves as an introduction to the genre and to a more complete assessment of the development of Early Modern political thought. The volume also stresses the importance of this genre for several transformations of political thought in the Early Modern Age. (shrink)

We treat meaning as nonphysical connection and potential organization. Meaning is a resource that can be used by animals to improve survival and reproduction. The evolu­tion of brains to exploit meaning occurred in two heuristic steps. First, solitary brains developed mental representations of patterns for learning and guiding adaptive action. Second, humankind greatly expanded the usefulness of meaning by using it collectively, such as by deliberately communicating information, creating a body of shared beliefs and understandings, and using meaning to organize (...) social life. The intentional application of meaning to life, as in the quest for a meaningful life, is a later development linked to ways of organizing behavior to maximize future outcomes and relate the individual to societal systems.

There is a puzzle about why self-deception, a process that obscures the truth, is so pervasive in human behavior given that tracking the truth seems important for our survival and reproduction. William von Hippel and Robert Trivers argue that, despite appearances, there is good reason to think that self-deception is an adaptation by arguing: self-deception leads to a positive self-perception and a positive self-perception increases an individual’s fitness. D.S. Neil Van Leeuwen, however, gives persuasive arguments against both steps. (...) In response, we will defend both propositions, thereby supporting the conclusion that self-deception indeed has adaptive value. The first premise will be bolstered by a survey of the philosophical literature and empirical work on self-deception, whereas the second will be strengthened by empirical research on a behavioral phenomenon known as the winner effect.

Area number x is called k-monotonically computable , for constant k > 0, if there is a computable sequence n ∈ ℕ of rational numbers which converges to x such that the convergence is k-monotonic in the sense that k · |x — xn| ≥ |x — xm| for any m > n and x is monotonically computable if it is k-mc for some k > 0. x is weakly computable if there is a computable sequence s ∈ ℕ of (...) rational numbers converging to x such that the sum equation image|xs — xs + 1| is finite. In this paper we show that a mc real numbers are weakly computable but the converse fails. Furthermore, we show also an infinite hierarchy of mc real numbers. (shrink)
