Abstract Unlike the question of whether self‐deception can be understood on model other‐deception, relationship between two phenomena at level practice is hardly ever explored. Other‐deception support and vice versa. Self‐deception often affects not only beliefs behavior self‐deceiving person but also others who may become accomplices self‐deception. As I will show, however, it difficult to des...

To what extent do self-deception and delusion overlap? In this paper we argue that both self-deception and delusions can be understood in folk-psychological terms. "Motivated" delusions, just like self-deception, can be described as beliefs driven by personal interests. If self-deception can be understood folk-psychologically because of its motivational component, so can motivated delusions. No...

Regulated by self-consciousness, self-deception is a part of the self-system that suppresses negative aspects of the self and maintains a positive moral self-concept. We tested this evolutionary hypothesis on 166 college students by measuring self-deception using both a questionnaire and a series of hypothetical helping scenarios. The results showed a positive correlation between self-deception...

Self-deception has long been the subject of speculation and controversy in psychology, evolutionary biology and philosophy. According to an influential 'deflationary' view, the concept is an over-interpretation of what is in reality an instance of motivationally biased judgement. The opposite view takes the interpersonal deception analogy seriously, and holds that some part of the self actively...

BACKGROUND This study was aimed at: (i) examining levels of self-deception in substance dependent individuals following addiction treatment, and (ii) examining the association between participants’ levels of self-deception and (a) personality disorders, (b) addiction-related beliefs, (c) duration of abstinence, and (d) estimates of craving. METHOD We administered self-report questionnai...

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 m...

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: (1) self-deception leads to a positive self-perceptio...

Scholars from many disciplines have investigated selfdeception, but defining self-deception and establishing its possible benefits have been a matter of heated debate — a debate impoverished by a relative lack of empirical research. Drawing on recent research, we first classify three distinct definitions of self-deception, ranging from a view that selfdeception is synonymous with positive illus...
