Abduction, deduction and induction 7 with the development of new theoretical terms such as “quark,” and “gene.” Indeed, Peirce (1934/1960) emphasized that abduction is the only logical operation that introduces new ideas. “Deduction, induction, and abduction are like three parts of the same puzzle, and all formal reasoning is done using them and only them. For example: the only swans Europeans had ever seen were white and so they made the generalisation “all swans are white”. The distinction between deduction, on the one hand, and induction and abduction, on the other hand, corresponds to the distinction between necessary and non-necessary inferences. These three approaches tell us how we are treating data and theories. The key difference between induction and abduction is that abductive reasoning is used to speculate a connection between data points that seem to relate but might not relate in order to form a hypothesis, and inductive reasoning involves considering data points that likely relate and drawing a conclusion. Induction seeks to produce some form of generalisation whereas abduction is restricted to an explanation of the particular circumstances under consideration. Induction: From argument finding to explanation of data; Inductive reasoning is when you conclude something based on observations. Sometimes this is informally called a “top-down” approach. It starts with an observation or set of observations and then seeks to find the simplest and most likely conclusion from the observations. It doesn't deductively follow that I will but there's an uncomfortably high probability. In logic, we often refer to the two broad methods of reasoning as the deductive and inductive approaches.. Deductive reasoning works from the more general to the more specific. Difference between Deductive, Inductive and Abductive Research. Specifically, deductive reasoning is criticized for the lack of clarity in terms of how to select theory to be tested via formulating hypotheses. Abductive reasoning (also called abduction, abductive inference, or retroduction) is a form of logical inference formulated and advanced by American philosopher Charles Sanders Peirce beginning in the last third of the 19th century. Some of the workshop participants adhere to the inferential perspective, and therefore view induction as a special case of abduction, while others favour the syllogistic perspective, and therefore stress the differences between abduction and induction.

It is an inductive inference that if I smoke 60 cigarettes a day for twenty years, I will get lung cancer. In this paper, we show how an appropriate possible world semantics exhibits the fundamental differences between various forms of logical reasoning such as deduction, abduction and induction. Maybe one difference between induction and abduction is that induction often relies on regularities or lawlike correlations. Deduction & Induction. In theoretical research, deduction, induction and abduction can be also known as modes of argumentation: Deduction: Data finding first to support an argument. These points formed a central part of the discussion in the panels that followed. 3.
