Wishful thinking is the formation of beliefs based on what might be pleasing to imagine, rather than on evidence, rationality, or reality. It is a product of resolving conflicts between belief and desire.[1] Methodologies to examine wishful thinking are diverse. Various disciplines and schools of thought examine related mechanisms such as neural circuitry, human cognition and emotion, types of bias, procrastination, motivation, optimism, attention and environment. This concept has been examined as a fallacy. It is related to the concept of wishful seeing.
Some psychologists believe that positive thinking is able to positively influence behavior and so bring about better results. This is called the "Pygmalion effect".[2][3] Christopher Booker discussed wishful thinking in terms of "the fantasy cycle", which he described as "a pattern that recurs in personal lives, in politics, in history – and in storytelling." He added: "When we embark on a course of action which is unconsciously driven by wishful thinking, all may seem to go well for a time, in what may be called the 'dream stage'. But because this make-believe can never be reconciled with reality, it leads to a 'frustration stage' as things start to go wrong, prompting a more determined effort to keep the fantasy in being. As reality presses in, it leads to a 'nightmare stage' as everything goes wrong, culminating in an 'explosion into reality', when the fantasy finally falls apart."[4]
Studies have consistently shown that holding all else equal, subjects will have unrealistic optimism and predict positive outcomes to be more likely than negative outcomes. Research also suggests that under certain circumstances, such as when threat increases, a reverse phenomenon occurs.[5]
