Overconfidence
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. 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 data show that confidence systematically exceeds accuracy, implying people are more sure that they are correct than they deserve to be. If human confidence had perfect calibration, judgments with 100% confidence w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confidence
Confidence is the feeling of belief or trust that a person or thing is reliable. * * * Self-confidence is trust in oneself. Self-confidence involves a positive belief that one can generally accomplish what one wishes to do in the future. Self-confidence is not the same as self-esteem, which is an evaluation of one's worth. Self-confidence is related to self-efficacy—belief in one's ability to accomplish a specific task or goal. Confidence can be a self-fulfilling prophecy, as those without it may fail because they lack it, and those with it may succeed because they have it rather than because of an innate ability or skill. History Ideas about the causes and effects of self-confidence have appeared in English-language publications describing characteristics of a sacrilegious attitude toward God, the character of the British empire, and the culture of colonial-era American society. In 1890, the philosopher William James in his '' Principles of Psychology'' wrote, "Belie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Bias
A cognitive bias is a systematic pattern of deviation from norm (philosophy), norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the Objectivity (philosophy), objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, and irrationality. While cognitive biases may initially appear to be negative, some are adaptive. They may lead to more effective actions in a given context. Furthermore, allowing cognitive biases enables faster decisions which can be desirable when timeliness is more valuable than accuracy, as illustrated in Heuristic (psychology), heuristics. Other cognitive biases are a "by-product" of human processing limitations, resulting from a lack of appropriate mental mechanisms (bounded rationality), the impact of an individual's constitution and bi ...

Core Self-evaluations
Core self-evaluations (CSE) represent a stable personality trait which encompasses an individual's subconscious, fundamental evaluations about themselves, their own abilities and their own control. People who have high core self-evaluations will think positively of themselves and be confident in their own abilities. Conversely, people with low core self-evaluations will have a negative appraisal of themselves and will lack confidence. The concept of core self-evaluations was first examined by Judge, Locke, and Durham (1997)The concept of core evaluation was first identified by clinical psychologist Edith Packer and presented in her lecture "Understanding the Subconscious" in 1984. https://www.amazon.com/dp/B00ENAPR3S/ and involves four personality dimensions: locus of control, neuroticism, generalized self-efficacy, and self-esteem. The trait developed as a dispositional predictor of job satisfaction, but has expanded to predict a variety of other outcomes. Core self-evaluation ...

Illusion Of Control
The illusion of control is the tendency for people to overestimate their ability to control events. It was named by U.S. psychologist Ellen Langer and is thought to influence gambling behavior and belief in the paranormal. Along with illusory superiority and optimism bias, the illusion of control is one of the positive illusions. Definition The illusion of control is the tendency for people to overestimate their ability to control events, for example, when someone feels a sense of control over outcomes that they demonstrably do not influence. The illusion might arise because a person lacks direct introspective insight into whether they are in control of events. This has been called the introspection illusion. Instead, they may judge their degree of control by a process which is often unreliable. As a result, they see themselves as responsible for events to which there is little or no causal link. For example, in one study, college students were in a virtual reality setting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titan Submersible Implosion
On 18 June 2023, Titan (submersible), ''Titan'', a submersible operated by the American tourism and expeditions company OceanGate, Implosion (mechanical process), imploded during an expedition to view the Wreck of the Titanic, wreck of the ''Titanic'' in the Atlantic Ocean, North Atlantic Ocean off the coast of Newfoundland (island), Newfoundland, Canada. Aboard the submersible were Stockton Rush, the American chief executive officer of OceanGate; Paul-Henri Nargeolet, a French deep-sea explorer and ''Titanic'' expert; Hamish Harding, a British businessman; Shahzada Dawood, a Pakistani-British businessman; and Dawood's son, Suleman. Communication between ''Titan'' and its mother ship, , was lost 1 hour and 33 minutes into the dive. Authorities were alerted when it failed to resurface at the scheduled time later that day. After the submersible had been missing for four days, a remotely operated underwater vehicle (ROV) discovered a debris field containing parts of ''Titan'', a ...

Deepwater Horizon Oil Spill
The ''Deepwater Horizon'' oil spill was an environmental disaster off the coast of the United States in the Gulf of Mexico, on the BP-operated Macondo Prospect. It is considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. Caused in the aftermath of a blowout and explosion on the Deepwater Horizon oil platform, the United States federal government estimated the total discharge at . After Efforts to stem the Deepwater Horizon oil spill, several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The ''Deepwater Horizon'' oil spill is regarded as one of the largest environmental disasters in world history. A massive response ensued to protect beaches, salt marsh, wetlands and Estuary, estuaries from the spreading oil util ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chernobyl Disaster
On 26 April 1986, the no. 4 reactor of the Chernobyl Nuclear Power Plant, located near Pripyat, Ukrainian Soviet Socialist Republic, Ukrainian SSR, Soviet Union (now Ukraine), exploded. With dozens of direct casualties, it is one of only two nuclear energy accidents rated at the maximum severity on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear accident. The response involved more than Chernobyl liquidators, 500,000 personnel and cost an estimated 18billion Soviet ruble, rubles (about $84.5billion USD in 2025). It remains the worst nuclear disaster and the List of disasters by cost, most expensive disaster in history, with an estimated cost of US$700 billion. The disaster occurred while running a test to simulate cooling the reactor during an accident in blackout conditions. The operators carried out the test despite an accidental drop in reactor power, and due to a design issue, attempting to shut down the reactor in those conditio ...

Safety Culture
Safety culture is the element of organizational culture which is concerned with the maintenance of safety and compliance with safety standards. It is informed by the organization's leadership and the beliefs, perceptions and values that employees share in relation to risks within the organization, workplace or community. Safety culture has been described in a variety of ways: notably, the National Academies of Science and the Association of Land Grant and Public Universities have published summaries on this topic in 2014 and 2016. A good safety culture can be promoted by senior management commitment to safety, realistic practices for handling hazards, continuous organisational learning, and care and concern for hazards shared across the workforce. Beyond organisational learning, individual training forms the foundation from which to build a systemic safety culture. History The Chernobyl disaster highlighted the importance of safety culture and the effect of managerial and hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
