(Image credit: Sally Anscombe/Getty) What is abductive reasoningĪnother form of scientific reasoning that diverges from inductive and deductive reasoning is abductive. This is an example of inductive reasoning. If every dog you meet is friendly, it is reasonable to form the hypothesis that most dogs are usually friendly. Major premise: All plants perform photosynthesis.Ĭonclusion: A cactus performs photosynthesis.

Major premise: All mammals have backbones. Here are some examples of deductive reasoning: Deductive reasoning then allows them to apply the theories to specific situations. Nevertheless, inductive reasoning has its place in the scientific method, and scientists use it to form hypotheses and theories. Therefore, all birds can't fly.' The conclusion does not follow logically from the statements. Here's another example: 'Penguins are birds. Using inductive logic, you might then propose that all of the coins in the bag are pennies.'Even though all of the initial observations - that each coin taken from the bag was a penny - are correct, inductive reasoning does not guarantee that the conclusion will be true. For instance, let's say that you have a bag of coins you pull three coins from the bag, and each coin is a penny. In other words, the reliability of a conclusion made with inductive logic depends on the completeness of the observations. 'In science, there is a constant interplay between inductive inference (based on observations) and deductive inference (based on theory), until we get closer and closer to the 'truth,' which we can only approach but not ascertain with complete certainty.' We make many observations, discern a pattern, make a generalization, and infer an explanation or a theory,' Wassertheil-Smoller told Live Science. 'In inductive inference, we go from the specific to the general. There is data, and then conclusions are drawn from the data this is called inductive logic, according to the University of Illinois (opens in new tab) in Springfield. While deductive reasoning begins with a premise that is proven through observations, inductive reasoning extracts a likely (but not certain) premise from specific and limited observations. Inductive reasoning moves from observation, to generalization to theory.
