Team Error
Team Error refers to errors that occur in settings where multiple people are working together. Dependency increases the likelihood of human error due to interactions with other seemingly independent defense mechanisms. Engaging multiple people to perform a task does not ensure that the task will be done correctly. One potential dependency is team error, an error of one or more members that allows other individual members of the same group to make a mistake. Common types of team errors *Halo Effect – Immediate judgment discrepancy or cognitive bias, where a person making an initial assessment will assume the validity of ambiguous information based upon concrete information: blind trust in the competence of specific individuals because of their experience or education. *Pilot/Copilot – Reluctance of a subordinate to challenge the opinions, decisions, or actions of a superior. *Free Riding – Tendency to “tag along” without actively scrutinizing the intent and actions of anoth ...

Halo Effect
The halo effect (sometimes called the halo error) is the tendency for positive impressions of a person, company, brand, or product in one area to positively influence one's opinion or feelings in other areas. Halo effect is “the name given to the phenomenon whereby evaluators tend to be influenced by their previous judgments of performance or personality.” The halo effect is a cognitive bias which can possibly prevent someone from accepting a person, a product or a brand based on the idea of an unfounded belief on what is good or bad. The term was coined by Edward Thorndike. A simplified example of the halo effect is when a person notices that an individual in a photograph is attractive, well groomed, and properly attired, they assume, using a mental heuristic, that the person in the photograph is a good person based upon the rules of their own social concept. This constant error in judgment is reflective of the individual's preferences, prejudices, ideology, aspirations, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groupthink
Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Cohesiveness, or the desire for cohesiveness, in a group may produce a tendency among its members to agree at all costs. This causes the group to minimize conflict and reach a consensus decision without critical evaluation. Groupthink is a construct of social psychology, but has an extensive reach and influences literature in the fields of communication studies, political science, management, and organizational theory, as well as important aspects of deviant religious cult behaviour. Overview Groupthink is sometimes stated to occur (more broadly) within natural groups within the community, for example to explain the lifelong different mindsets of those with differing political views (such as "conservatism" and "liberalism" in the U.S. political context or the purported benefits ...

Diffusion Of Responsibility
Diffusion of responsibility is a sociopsychological phenomenon whereby a person is less likely to take responsibility for action or inaction when other bystanders or witnesses are present. Considered a form of attribution, the individual assumes that others either are responsible for taking action or have already done so.Ciccarelli, S. K. & White, J. N. (2009). ''Psychology'' (2nd ed.) New Jersey: Pearson Education. . The diffusion of responsibility refers to the decreased responsibility of action each member of a group feels when they are part of a group. For example, in emergency situations, individuals feel less responsibility to respond or call for help if they know that there are others also watching the situation - if they know they are a part of the group of witnesses. In other group settings (in which a group is appointed to complete a task or reach a certain goal), the diffusion of responsibility manifests itself as the decreased responsibility each member feels to con ...

Social Psychology (sociology)
In sociology, social psychology (also known as sociological social psychology) studies the relationship between the individual and society. Although studying many of the same substantive topics as its counterpart in the field of psychology, sociological social psychology places relatively more emphasis on the influence of social structure and culture on individual outcomes, such as personality, behavior, and one's position in social hierarchies. Researchers broadly focus on higher levels of analysis, directing attention mainly to groups and the arrangement of relationships among people. This subfield of sociology is broadly recognized as having three major perspectives: Symbolic interactionism, social structure and personality, and structural social psychology. Some of the major topics in this field include social status, structural power, sociocultural change, social inequality and prejudice, leadership and intra-group behavior, social exchange, group conflict, impression ...

United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Error
Human error refers to something having been done that was " not intended by the actor; not desired by a set of rules or an external observer; or that led the task or system outside its acceptable limits".Senders, J.W. and Moray, N.P. (1991) Human Error: Cause, Prediction, and Reduction'. Lawrence Erlbaum Associates, p.25. . Human error has been cited as a primary cause contributing factor in disasters and accidents in industries as diverse as nuclear power (e.g., the Three Mile Island accident), aviation (see pilot error), space exploration (e.g., the Space Shuttle Challenger disaster and Space Shuttle Columbia disaster), and medicine (see medical error). Prevention of human error is generally seen as a major contributor to reliability and safety of (complex) systems. Human error is one of the many contributing causes of risk events. Definition Human error refers to something having been done that was "not intended by the actor; not desired by a set of rules or an external observer ...

Human Reliability
Human reliability (also known as human performance or HU) is related to the field of human factors and ergonomics, and refers to the reliability of humans in fields including manufacturing, medicine and nuclear power. Human performance can be affected by many factors such as age, state of mind, physical health, attitude, emotions, propensity for certain common mistakes, errors and cognitive biases, etc. Human reliability is very important due to the contributions of humans to the resilience of systems and to possible adverse consequences of human errors or oversights, especially when the human is a crucial part of the large socio-technical systems as is common today. User-centered design and error-tolerant design are just two of many terms used to describe efforts to make technology better suited to operation by humans. Common Traps of Human Nature People tend to overestimate their ability to maintain control when they are doing work. The common characteristics of human nat ...

Latent Human Error
Latent human error is a term used in safety work and accident prevention, especially in aviation, to describe human errors which are likely to be made due to systems or routines that are formed in such a way that humans are disposed to making these errors. Latent human errors are frequently components in causes of accidents. The error is latent and may not materialize immediately, thus, latent human error does not cause immediate or obvious damage. Discovering latent errors is therefore difficult and requires a systematic approach. Latent human error is often discussed in aviation incident investigation, and contributes to over 70% of the accidents. By gathering data about errors made, then collating, grouping and analyzing them, it can be determined whether a disproportionate amount of similar errors are being made. If this is the case, a contributing factor may be disharmony between the respective systems/routines and human nature or propensities. The routines or systems can the ...

Pilot Error
Pilot error generally refers to an Aviation accidents and incidents, accident in which an action or decision made by the Aircraft pilot#Airline, pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. Chicago Convention on International Civil Aviation, Chicago Convention defines accident as "An occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of the "pilot error" does not include deliberate crash (and such crash is not an accident). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs to teach crew members how t ...

Cascading Failure
A cascading failure is a failure in a system of interconnected parts in which the failure of one or few parts leads to the failure of other parts, growing progressively as a result of positive feedback. This can occur when a single part fails, increasing the probability that other portions of the system fail. Such a failure may happen in many types of systems, including power transmission, computer networking, finance, transportation systems, organisms, the human body, and ecosystems. Cascading failures may occur when one part of the system fails. When this happens, other parts must then compensate for the failed component. This in turn overloads these nodes, causing them to fail as well, prompting additional nodes to fail one after another. In power transmission Cascading failure is common in power grids when one of the elements fails (completely or partially) and shifts its load to nearby elements in the system. Those nearby elements are then pushed beyond their capacity s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cognitive Biases
A cognitive bias is a systematic pattern of deviation from 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 objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality. Although it may seem like such misperceptions would be aberrations, biases can help humans find commonalities and shortcuts to assist in the navigation of common situations in life. Some cognitive biases are presumably adaptive. Cognitive biases 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 heuristics. Other cognitive biases are a "by-product" of human processing limitations, resulting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
