Positive illusions are unrealistically favorable attitudes that people have towards themselves or to people that are close to them. Positive illusions are a form of self-deception or self-enhancement that feel good, maintain self-esteem or stave off discomfort at least in the short term. There are three broad kinds: inflated assessment of one's own abilities, unrealistic optimism about the future and an illusion of control. The term "positive illusions" originates in a 1988 paper by Taylor and Brown.〔 "Taylor and Brown's (1988) model of mental health maintains that certain positive illusions are highly prevalent in normal thought and predictive of criteria traditionally associated with mental health." There are controversies about the extent to which people reliably demonstrate positive illusions, and also about whether these illusions are beneficial to the people who have them.〔 ==Types== In the above-average effect, people regard themselves more positively than they regard others and less negatively than others regard them. Moreover, positive attributes are judged to be more descriptive of themselves than of an average person, whereas negative ones are judged to be less descriptive of themselves than of an average person. Despite the fact that it is statistically impossible for most people to be superior to their peers, rather than being equally aware of ones strengths and weaknesses, people are more aware of their strengths and not very aware of their weaknesses. In short, people tend to believe they are much more competent than they are. This effect has been widely recognized across traits and abilities including the realm of driving ability, parenting, leadership ability, teaching ability, ethics, and health. This effect is also evident in memory; most people also tend to perceive their ability to remember as better than it actually is.〔Crary, 1966〕 The illusion of control is an exaggerated assessment of the individual's personal control over environmental circumstances such as the roll of dice or flip of coin.〔Fleming & Darley, 1989〕 Optimism bias is a tendency for people to overestimate their likelihood of experiencing a wide variety of pleasant events, such as enjoying their first job or having a gifted child, and somewhat underestimate their risk of succumbing to negative events, such as getting divorced or falling victim to a chronic disease. This illusory nature of optimism is also evident in peoples' under-estimation of the time taken for a variety of tasks.〔Buelher et al., 1994〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「positive illusions」の詳細全文を読む スポンサード リンク
