Ignorance is a lack of knowledge or understanding. Deliberate ignorance is a culturally-induced phenomenon, the study of which is called agnotology.
Egocentric bias is the tendency to rely too heavily on one's own perspective and/or have a higher opinion of oneself than reality. It appears to be the result of the psychological need to satisfy one's ego and to be advantageous for memory consolidation. Research has shown that experiences, ideas, and beliefs are more easily recalled when they match one's own, causing an egocentric outlook. Michael Ross and Fiore Sicoly first identified this cognitive bias in their 1979 paper, "Egocentric biases in availability and attribution". Egocentric bias is referred to by most psychologists as a general umbrella term under which other related phenomena fall.
In psychology, the false consensus effect, also known as consensus bias, is a pervasive cognitive bias that causes people to "see their own behavioral choices and judgments as relatively common and appropriate to existing circumstances". In other words, they assume that their personal qualities, characteristics, beliefs, and actions are relatively widespread through the general population.
The worse-than-average effect or below-average effect is the human tendency to underestimate one's achievements and capabilities in relation to others.
The planning fallacy is a phenomenon in which predictions about how much time will be needed to complete a future task display an optimism bias and underestimate the time needed. This phenomenon sometimes occurs regardless of the individual's knowledge that past tasks of a similar nature have taken longer to complete than generally planned. The bias affects predictions only about one's own tasks. On the other hand, when outside observers predict task completion times, they tend to exhibit a pessimistic bias, overestimating the time needed. The planning fallacy involves estimates of task completion times more optimistic than those encountered in similar projects in the past.
The Dunning–Kruger effect is a cognitive bias in which people with limited competence in a particular domain overestimate their abilities. It was first described by Justin Kruger and David Dunning in 1999. Some researchers also include the opposite effect for high performers: their tendency to underestimate their skills. In popular culture, the Dunning–Kruger effect is often misunderstood as a claim about general overconfidence of people with low intelligence instead of specific overconfidence of people unskilled at a particular task.
The overconfidence effect is a well-established bias in which a person's subjective confidence in their judgments is reliably greater than the objective accuracy of those judgments, especially when confidence is relatively high. Overconfidence is one example of a miscalibration of subjective probabilities. Throughout the research literature, overconfidence has been defined in three distinct ways: (1) overestimation of one's actual performance; (2) overplacement of one's performance relative to others; and (3) overprecision in expressing unwarranted certainty in the accuracy of one's beliefs.
Optimism bias is a cognitive bias that causes someone to believe that they themselves are less likely to experience a negative event. It is also known as delusional optimism, unrealistic optimism or comparative optimism.
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 avoid discomfort, at least in the short term. There are three general forms: 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."
Self-enhancement is a type of motivation that works to make people feel good about themselves and to maintain self-esteem. This motive becomes especially prominent in situations of threat, failure or blows to one's self-esteem. Self-enhancement involves a preference for positive over negative self-views. It is one of the three self-evaluation motives along with self-assessment and self-verification . Self-evaluation motives drive the process of self-regulation, that is, how people control and direct their own actions.
In social psychology, illusory superiority is a cognitive bias wherein people overestimate their own qualities and abilities compared to others. Illusory superiority is one of many positive illusions, relating to the self, that are evident in the study of intelligence, the effective performance of tasks and tests, and the possession of desirable personal characteristics and personality traits. Overestimation of abilities compared to an objective measure is known as the overconfidence effect.
The spotlight effect is the psychological phenomenon by which people tend to believe they are being noticed more than they really are. Being that one is constantly in the center of one's own world, an accurate evaluation of how much one is noticed by others is uncommon. The reason for the spotlight effect is the innate tendency to forget that although one is the center of one's own world, one is not the center of everyone else's. This tendency is especially prominent when one does something atypical.
Naïve cynicism is a philosophy of mind, cognitive bias and form of psychological egoism that occurs when people naïvely expect more egocentric bias in others than actually is the case.
The hard–easy effect is a cognitive bias that manifests itself as a tendency to overestimate the probability of one's success at a task perceived as hard, and to underestimate the likelihood of one's success at a task perceived as easy. The hard-easy effect takes place, for example, when individuals exhibit a degree of underconfidence in answering relatively easy questions and a degree of overconfidence in answering relatively difficult questions. "Hard tasks tend to produce overconfidence but worse-than-average perceptions," reported Katherine A. Burson, Richard P. Larrick, and Jack B. Soll in a 2005 study, "whereas easy tasks tend to produce underconfidence and better-than-average effects."
The frog pond effect is the theory that individuals evaluate themselves as worse than they actually are when in a group of higher-performing individuals. This effect is a part of the wider social comparison theory. It relates to how individuals evaluate themselves based on comparisons to other people around them, and is generally due to upward comparisons toward people who are better than themselves.
David Alan Dunning is an American social psychologist and professor of psychology at the University of Michigan. He is a retired professor of psychology at Cornell University.
The false-uniqueness effect is an attributional type of cognitive bias in social psychology that describes how people tend to view their qualities, traits, and personal attributes as unique when in reality they are not. This bias is often measured by looking at the difference between estimates that people make about how many of their peers share a certain trait or behaviour and the actual number of peers who report these traits and behaviours.
The liking gap is the disparity between how much a person believes that another person likes them, and that other person's actual opinion. Studies have found that most people underestimate how much other people like them and enjoy their company.
The illusion of explanatory depth (IOED) is cognitive bias or an illusion where people tend to believe they understand a topic better than they actually do. The term was coined by Yale researchers Leonid Rozenblit and Frank Keil in 2002. The effect was observed in only one type of knowledge called explanatory knowledge, in this case defined as "knowledge that involves complex causal patterns". The effect has not been observed in procedural, narrative, or factual (descriptive) knowledge. Evidence of the IOED occurring has been found in everyday mechanical and electrical devices such as bicycles, in addition to mental disorders, natural phenomena, folk theories, and politics, with the most studied effect of IOED being in politics in the form of political polarization.
