Twenty years ago, writers wrote and readers read. The web lets readers respond, and increasingly they do—in comment threads, on forums, and in their own blog posts. Many who respond to something disagree with it. That's to be expected. The result is there's a lot more disagreeing going on, especially measured by the word. If we're all going to be disagreeing more, we should be careful to do it well. DH0. This is the lowest form of disagreement, and probably also the most common. Logic. Logic (from the Ancient Greek: λογική, logike) is the branch of philosophy concerned with the use and study of valid reasoning. The study of logic also features prominently in mathematics and computer science.
Logic is often divided into three parts: inductive reasoning, abductive reasoning, and deductive reasoning. List of fallacies. Formal fallacy. In philosophy, a formal fallacy is a pattern of reasoning that is always wrong.
This is due to a flaw in the logical structure of the argument which renders the argument invalid. A formal fallacy is contrasted with an informal fallacy, which may have a valid logical form and yet be unsound because one or more premises are false. The term fallacy is often used generally to mean an argument that is problematic for any reason, whether it is formal or informal. The presence of a formal fallacy in a deductive argument does not imply anything about the argument's premises or its conclusion. Both may actually be true, or even more probable as a result of the argument, but the deductive argument is still invalid because the conclusion does not follow from the premises in the manner described. "Fallacious arguments usually have the deceptive appearance of being good arguments A different approach to understanding and classifying fallacies is provided by argumentation theory.
Common examples Informal logic. Informal logic is associated with (informal) fallacies, critical thinking, the Thinking Skills Movement and the interdisciplinary inquiry known as argumentation theory.
Frans H. van Eemeren writes that the label "informal logic" covers a "collection of normative approaches to the study of reasoning in ordinary language that remain closer to the practice of argumentation than formal logic. " History The field perhaps became recognized under its current name with the First International Symposium on Informal Logic held in 1978.
David Hitchcock argues that the naming of the field was unfortunate, and that philosophy of argument would have been more appropriate. Bias. Bias is an inclination of temperament or outlook to present or hold a partial perspective, often accompanied by a refusal to consider the possible merits of alternative points of view.
People may be biased toward or against an individual, a race, a religion, a social class, a political party, or a species. Biased means one-sided, lacking a neutral viewpoint, not having an open mind. Cognitive bias. Some cognitive biases are presumably adaptive.
Cognitive biases may lead to more effective actions in a given context. Furthermore, cognitive biases enable faster decisions 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), or simply from a limited capacity for information processing. A continually evolving list of cognitive biases has been identified over the last six decades of research on human judgment and decision-making in cognitive science, social psychology, and behavioral economics. Cognitive biases are important to study because "systematic errors" highlight the "psychological processes that underlie perception and judgement" (Tversky & Kahneman,1999, p. 582).
Overview Bias arises from various processes that are sometimes difficult to distinguish. Types List of cognitive biases. Cognitive biases are tendencies to think in certain ways that can lead to systematic deviations from a "standard of rationality" or good judgment, and are often studied in psychology and behavioral economics. There are also controversies as to whether some of these biases count as useless, irrational or whether they result in useful attitudes or behavior.
For example, when getting to know others, people tend to ask leading questions which seem biased towards confirming their assumptions about the person. This kind of confirmation bias has been argued to be an example of social skill: a way to establish a connection with the other person. The research on these biases overwhelmingly involves human subjects. However, some of the findings have appeared in non-human animals as well. Decision-making, belief, and behavioral biases
