How does overconfidence affect decision-making?

Overconfidence, on the other hand, was linked to weaker metacognitive capacity "Mr. Trautwein, a co-first author, also contributed. "When the findings are combined, they show that, while confidence has a reward-like component, it may lead to overconfidence, which can hinder decision making. This is because people who are overconfident tend to ignore or discount evidence that conflicts with their view of the world.

"Our study provides novel evidence that people's perceptions of their own ability affect how they make decisions," said Mr. Trautwein. "Specifically, individuals who judge themselves to be highly competent are less likely to consider negative information about their choices."

The researchers also found that women were more likely than men to consider both positive and negative information when making decisions. However, women were only slightly more likely than men to rate themselves as very confident in their judgments.

Why do some people seem to have an easier time believing in themselves than others? Perhaps being confident gives you reason to believe that you can succeed at something, which in turn makes it more likely that you will. Or maybe confident people just talk more about what they know well -- which would explain why women who think they're good at judging aesthetics are so much more likely to say they're sure about their choice than men who claim to be skilled at determining beauty.

What is the overconfidence effect in psychology?

When people's subjective belief in their own competence exceeds their objective (real) performance, the overconfidence effect occurs (Pallier et al., 2002). It is usually assessed by having experimental participants respond to general knowledge exam questions. The overconfidence effect has been found in a wide range of tasks and subjects, including businesspeople (Kahneman & Frederick, 2005), medical students (Rosenbaum et al., 2001), psychologists (Pfister et al., 2007; Ross et al., 2011), and teachers (Bond & Schneider, 1996).

The overconfidence effect has been explained with two different theories: the threshold theory and the response bias theory. The threshold theory suggests that people estimate they can do a task within some threshold value, so if their actual performance falls below this threshold, they will feel incompetent even though they are not.

The response bias theory proposes that people have a desire to believe they are good at things, so they will give answers that justify their beliefs. This means that if people think they are not very competent, they will give wrong answers more often than not.

These theories make similar predictions about how the overconfidence effect should affect participants' responses on different types of questions.

Is overconfidence an emotion?

Overconfidence is associated with self-conscious feelings since it shows a positive bias of exaggerated appraisal of one's own abilities. Overconfidence may also be caused by a lack of motivation to find out if one is wrong, or by a desire to justify incorrect decisions. In addition, overconfident people are likely to ignore warning signs that their behavior is inappropriate or detrimental to their interests.

Overconfidence has been observed in animals as well as humans. Animals, too, tend to overestimate their chances of success when hunting or mating. In one experiment with monkeys, scientists showed that the more confident they were in their ability to pick winning lottery numbers, the more likely they were to choose those numbers themselves. This pattern held true even when the chance of success was only 10%.

People also tend to be overconfident in situations where they have little experience, such as when giving testimony in court or playing online games. Studies show that jurors who vote "guilty" before hearing all the evidence are more likely to do so again if they were previously overconfident in reaching their decision. In experiments using computer games, overconfident players were more likely to continue playing, suggesting that they did not believe they could be losing.

Is overconfidence a heuristic?

Heuristic of overconfidence The heuristic of overconfidence is a psychological mechanism that governs how we evaluate the correctness of our stored information and perceptual models. Humans exhibit more trust in the correctness of their information and behaviors than is justified, according to studies. For example, people estimate that they can identify correct answers to questions about others' minds in about 70% of cases when asked directly, but actual accuracy rates are closer to 95%. Even when provided with evidence that contradicts their beliefs, people rarely change their minds; instead, they adjust the evidence they use to justify their position or add new evidence in favor of that position.

Overconfident judgments may serve as a useful heuristic under certain conditions. For example, because of limited memory capacity and the need for efficiency, it may be beneficial to rely on quick estimates rather than careful evaluations of all available evidence. Also, because of the limitations of human perception and judgment, it may be advantageous to assume that what we see and know about the world is an accurate representation of reality. Finally, because of the costs of correction, it may be preferable to keep quiet about one's errors or to simply move on.

People tend to be overconfident in several areas of life.
