THE OVERCONFIDENCE OF THE SUPER EGO.

Confidence has a common meaning of a certainty about handling something, such as work, family, social events, or relationships. It can be defined as the self-fulfilling prediction that directly or indirectly causes itself to become true, due to the positive feedback between belief and behavior. Those without it may fail or not try because they lack it.
Some others have defined confidence as a state of being certain that a hypothesis or prediction is correct or that a chosen course of action is the best or most effective.
The term Arrogance (Hubris) in this comparison is described as a personality quality of extreme or foolish pride or dangerous overconfidence without any regard of failure.
Overconfidence defies the normal course of confidence which in turn brings about the downfall, or nemesis, of the perpetrators. It has been called the most pervasive and potentially catastrophic of all the cognitive biases in which human beings fall victim.
Daniel Kahneman (March 5, 19340), an Israeli-American psychologist notable for his work on the psychology of judgment and decision-making, says: "Overconfident professionals sincerely believe they have expertise, act as experts, and look like experts. You will have to struggle to remind yourself that they may be in the grip of an illusion."
The ingredients of overconfidence can be defined in 3 distinct ways: overestimation of one's actual performance; over-placement of one's performance relative to others; and over-precision in expressing unwarranted certainty in the accuracy of one's beliefs.
The most common way in which overconfidence has been studied is by asking people how confident they are of specific beliefs they hold or answers they provide. The responses show that confidence systematically exceeds accuracy as the subject is answering hard questions about an unfamiliar topic, implying people are more sure that they correct than they deserve to be. This includes the illusion of control, and planning fallacy. Illusion of control describes the tendency for people to behave as if they might have control when in fact they have none. The planning fallacy describes the tendency for people to overestimate their rate of work or to underestimate how long it will take them to get things done.
Motivation theories have suggested that a successful performance hinges on both skill and will. Yet, even a motivated and skilled individual can fail if he/she does not have a personal certainty belief that he/she can handle what it takes or what needs to be done. Faith and Trust are synonyms of confidence when used in this sense. Then overconfidence, in this case, can be a powerful ingredient beneficial to individual self-esteem as well as giving an individual then will to succeed in their desired goal. Just believing and trusting in the right way to do things may give one the will to take one's endeavours further than those who do not.
