How to Disagree.

March 2008 The web is turning writing into a conversation.

How to Disagree

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. Logic. Logic (from the Ancient Greek: λογική, logike)[1] has two meanings: first, it describes the use of valid reasoning in some activity; second, it names the normative study of reasoning or a branch thereof.[2][3] In the latter sense, it features most prominently in the subjects of philosophy, mathematics, and computer science.

Logic

Logic was studied in several ancient civilizations, including India,[4] China,[5] Persia and Greece. In the West, logic was established as a formal discipline by Aristotle, who gave it a fundamental place in philosophy. The study of logic was part of the classical trivium, which also included grammar and rhetoric. Logic was further extended by Al-Farabi who categorized it into two separate groups (idea and proof). Later, Avicenna revived the study of logic and developed relationship between temporalis and the implication. Logic is often divided into three parts: inductive reasoning, abductive reasoning, and deductive reasoning.

List of fallacies. A fallacy is incorrect argument in logic and rhetoric resulting in a lack of validity, or more generally, a lack of soundness.

List of fallacies

Fallacies are either formal fallacies or informal fallacies. Formal fallacy. In philosophy, a formal fallacy is a pattern of reasoning that is always wrong.

Formal fallacy

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.

Informal logic. Informal logic is associated with (informal) fallacies, critical thinking, the Thinking Skills Movement[6] and the interdisciplinary inquiry known as argumentation theory.

Informal logic

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. "[7] History[edit] The field perhaps became recognized under its current name with the First International Symposium on Informal Logic held in 1978. 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.

Bias

People may be biased toward or against an individual, a race, a religion, a social class, a political party, or a species.[1] Biased means one-sided, lacking a neutral viewpoint, not having an open mind. Bias can come in many forms and is often considered to be synonymous with prejudice or bigotry.[2] Media bias is the bias of journalists and news producers within the mass media, in the selection of which events and stories are reported and how they are covered. The term "media bias" implies a pervasive or widespread bias contravening the standards of journalism, rather than the perspective of an individual journalist or article. The direction and degree of media bias in various countries is widely disputed. Other aspects[edit] See also[edit] References[edit]

Cognitive bias. Some cognitive biases are presumably adaptive.

Cognitive bias

Cognitive biases may lead to more effective actions in a given context.[7] Furthermore, cognitive biases enable faster decisions when timeliness is more valuable than accuracy, as illustrated in heuristics.[8] Other cognitive biases are a "by-product" of human processing limitations,[9] resulting from a lack of appropriate mental mechanisms (bounded rationality), or simply from a limited capacity for information processing.[10] 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[edit] Bias arises from various processes that are sometimes difficult to distinguish. 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.

List of cognitive biases

There are also controversies as to whether some of these biases count as truly 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.[6] The research on these biases overwhelmingly involves human subjects. However, some of the findings have appeared in non-human animals as well.
