Information Bias (psychology)

	Information Bias (psychology) Information bias is a cognitive bias to seek information when it does not affect action. People can often make better predictions or choices with less information: more information is not always better. An example of information bias is believing that the more information that can be acquired to make a decision, the better, even if that extra information is irrelevant for the decision. Example In an experiment , subjects considered this diagnostic problem involving fictitious diseases: A female patient is presenting symptoms and a history which both suggest a diagnosis of globoma, with about 80% probability. If it isn't globoma, it's either popitis or flapemia. Each disease has its own treatment which is ineffective against the other two diseases. A test called the ET scan would certainly yield a positive result if the patient had popitis, and a negative result if she has flapemia. If the patient has globoma, a positive and negative result are equally likely. If the ET scan was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cognitive Bias 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]
	Shared Information Bias Shared information bias (also known as the collective information sampling bias, or common-information bias) is known as the tendency for group members to spend more time and energy discussing information that all members are already familiar with (i.e., shared information), and less time and energy discussing information that only some members are aware of (i.e., unshared information).Forsyth, D. R. (2009). ''Group dynamics'' (5th ed.). Pacific Grove, CA: Brooks/Cole. Harmful consequences related to poor decision-making can arise when the group does not have access to unshared information (hidden profiles) in order to make a well-informed decision. Causes Although discussing unshared information may be enlightening, groups are often motivated to discuss shared information in order to reach group consensus on some course of action. According to Postmes, Spears, and Cihangir (2001), when group members are motivated by a desire to reach closure (e.g., a desire imposed by time cons ...

picture info	Cognitive Psychology Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s in a break from behaviorism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. The domain of cognitive psychology overlaps with that of cognitive science, which takes a more interdisciplinary approach and includes studies of non-human subjects and artificial intelligence. History Philosophically, ruminations on the human mind and its processes have been around since the times of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	List Of Cognitive Biases Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics. Although the reality of most of these biases is confirmed by reproducible research, there are often controversies about how to classify these biases or how to explain them. Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processingMartin Hilbert (2012) "Toward a synthesis of cognitive biases: How noisy information processing can bias human decision making"'. Psychological Bulletin, 138(2), 211–237; free access to the study here: https://www.martinhilbert.net/toward-a-synthesis-of-cognitive-biases/). Gerd Gigerenzer has criticized the framing of cognitive biases as errors in judgment, and favors interpreting them as arising from rational deviations from logical thought. Explanations include ...
