IKEA Effect
The IKEA effect is a cognitive bias in which consumers place a disproportionately high value on products they partially created. The name refers to Sweden, Swedish manufacturer and furniture retailer IKEA, which sells many Ready-to-assemble furniture, items of furniture that require assembly. A 2011 study found that subjects were willing to pay 63% more for furniture they had assembled themselves than for equivalent pre-assembled items. History and background The IKEA effect was identified and named by Michael I. Norton of Harvard Business School, Daniel Mochon of Yale, and Dan Ariely of Duke University, Duke, who published the results of three studies in 2011. They described the IKEA effect as "labor alone can be sufficient to induce greater liking for the fruits of one's labor: even constructing a standardized bureau, an arduous, solitary task, can lead people to overvalue their (often poorly constructed) creations." Norton, Mochon, and Ariely cited other researchers' previou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognition
Cognition is the "mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, imagination, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem-solving and decision-making, comprehension and production of language. Cognitive processes use existing knowledge to discover new knowledge. Cognitive processes are analyzed from very different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) are synthesized in the developing field of cognitive science, a progressively autonomou ...

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, 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 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 biological state (see embodied cognition), or simply from a limited c ...

Pygmalion Effect
The Pygmalion effect is a psychological phenomenon in which high expectations lead to improved performance in a given area. It is named after the Greek myth of Pygmalion, the sculptor who fell so much in love with the perfectly beautiful statue he created that the statue came to life. The psychologists Robert Rosenthal and Lenore Jacobson present a view, that has been called into question as a result of later research findings, in their book ''Pygmalion in the Classroom;'' borrowing something of the myth by advancing the idea that teachers' expectations of their students affect the students' performance. Rosenthal and Jacobson held that high expectations lead to better performance and low expectations lead to worse, both effects leading to self-fulfilling prophecy. According to the Pygmalion effect, the targets of the expectations internalize their positive labels, and those with positive labels succeed accordingly; a similar process works in the opposite direction in the case of ...

Omission Bias
Omission bias is the phenomenon in which people prefer omission (inaction) over commission (action), and tend to judge harm as a result of commission more negatively than harm as a result of omission. It can occur due to a number of processes, including psychological inertia, the perception of transaction costs, and the perception that commissions are more causal than omissions. In social political terms the Universal Declaration of Human Rights establishes how basic human rights are to be assessed in article 2, as "without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status." criteria that are often subject to one or another form of omission bias. It is controversial as to whether omission bias is a cognitive bias or is often rational. The bias is often showcased through the trolley problem and has also been described as an explanation for the endowment effect and status qu ...

Escalation Of Commitment
Escalation of commitment is a human behavior pattern in which an individual or group facing increasingly negative outcomes from a decision, action, or investment nevertheless continue the behavior instead of altering course. The actor maintains behaviors that are irrational, but align with previous decisions and actions. Economists and behavioral scientists use a related term, ''sunk-cost fallacy'', to describe the justification of increased investment of money or effort in a decision, based on the cumulative prior investment (" sunk cost") despite new evidence suggesting that the future cost of continuing the behavior outweighs the expected benefit. In sociology, ''irrational escalation of commitment'' or ''commitment bias'' describe similar behaviors. The phenomenon and the sentiment underlying them are reflected in such proverbial images as "throwing good money after bad", or "In for a penny, in for a pound", or "It's never the wrong time to make the right decision", or "I ...

Effort Justification
Effort justification is an idea and paradigm in social psychology stemming from Leon Festinger's theory of cognitive dissonance. Effort justification is a person's tendency to attribute the value of an outcome they put effort into achieving as greater than the objective value of the outcome. Theory and research Cognitive dissonance theory explains changes in people's attitudes or beliefs as the result of an attempt to reduce a dissonance (discrepancy) between contradicting ideas or cognitions. In the case of effort justification, there is a dissonance between the amount of effort exerted into achieving a goal or completing a task (high effort equalling high "cost") and the subjective reward for that effort (lower than was expected for such an effort). By adjusting and increasing one's attitude or subjective value of the goal, this dissonance is resolved. One of the first and most classic examples of effort justification is Aronson and Mills's study. A group of young women who vol ...

Dunning–Kruger Effect
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 the psychologists David Dunning and Justin Kruger 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. Numerous similar studies have been done. The Dunning–Kruger effect is usually measured by comparing self-assessment with objective performance. For example, participants may take a quiz and estimate their performance afterward, which is then compared to their actual results. The original study focused on logical reasoning, grammar, and social skills. Other studies have been conducted across a wide range of tasks. They in ...

Starlings
Starlings are small to medium-sized passerine (perching) birds known for the often dark, glossy iridescent sheen of their plumage; their complex vocalizations including mimicking; and their distinctive, often elaborate swarming behavior, known as murmuration. All members of the family ''Sturnidae'', commonly called sturnids, are known collectively as starlings. The Sturnidae are named for the genus ''Sturnus'', which in turn comes from the Latin word for starling, ''sturnus''. The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habi ...

Rats
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include ''Neotoma'' (pack rats), '' Bandicota'' (bandicoot rats) and ''Dipodomys'' (kangaroo rats). Rats are typically distinguished from mice by their size. Usually the common name of a large muroid rodent will include the word "rat", while a smaller muroid's name will include "mouse". The common terms ''rat'' and ''mouse'' are not taxonomically specific. There are 56 known species of rats in the world. Species and description The best-known rat species are the black rat (''Rattus rattus'') and the brown rat (''Rattus norvegicus''). This group, generally known as the Old World rats or true rats, originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over in the wild. The term ''rat'' is also used in the names of other small mammals that ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
