P1: You tell a secret only to your best friend, P2: The next day everyone knows your secret, C: Your best friend told other people your secret. Words associated with deductive reasoning: Inductive reasoning is a “bottom-up logic” in which conclusions are drawn from several observations and lead toward a general premise (Inductive reasoning goes from specific instances to general premises), Inductive arguments deal with probability not certainty. Abductive reasoning deductive starts with an incomplete set of observations and proceeds to the likeliest critical explanation for the group of observations, according to Butte College. Sound arguments are the strongest form of argument. Another type of reasoning, inductive, is also used. Share this link with a friend: Copied! We will discuss only the first two. An inference is a conclusion reached on the basis of evidence and reasoning. This way you can work up to the proposed solution and bring the audience along, so there is not as much dissonance when you finally get to the proposed solution. In an inductive argument if the premises are true, it’s highly likely the conclusion will be true, but it’s not 100% guaranteed. Inductive reasoning brings you to a conclusion from observations. A) Deductive B) Inductive. Inductive reasoning is a “bottom-up logic” in which conclusions are drawn from several observations and lead toward a general premise (Inductive reasoning goes from the specific to the general), “Inductive” means the observations are “drawn into” a general principle, Inductive reasoning can abstract and deviate from the information contained in the premises. A) Deductive B) Inductive. if I claim to be able to read minds or predict the future, then it’s up to me to provide evidence that I can, it’s not up to you to provide evidence that I can’t, Valid – a valid argument is simply one where, Invalid – any deductive argument that isn’t valid is invalid, Sound – a valid argument with true premises, Strong – an inductive argument is strong if the conclusion probably follows from the premises, Weak – any inductive argument that isn’t strong is weak, Cogent – a cogent argument is a strong argument with all true premises. If one or more premises were removed from the argument, the argument would still stand, Conductive arguments may even include “counter-premises” that go against the conclusion, A popular example of a conducive argument are the lists of pros and cons that people use to make decisions, P1: Thailand is a popular holiday destination. the sun will come up tomorrow, the laws of physics will continue to hold, effects will always follow causes etc. What is deductive reasoning?

Barbara Minto talks about the inductive and deductive forms of reasoning in her book “The Minto Pyramid” (p17). Do the premises necessarily lead to the conclusion? It. Then, from that rule, we make a true conclusion about something specific. We don’t know if inductive reasoning leads us to knowledge. Deductive reasoning is the most solid form of reasoning which gives us concrete conclusions as to whether our hypothesis was valid or not. Deductive and inductive reasoning are opposites -- deduction applies a top-to-bottom (general to specific) approach to reasoning whereas induction applies a bottom-to-top (specific to general) approach. Although it’s possible that the child’s dog really did eat his homework, it seems more likely that he didn’t do his homework and is using the “dog ate my homework” as an excuse. (1839– 1914).

Using Inductive Thinking to Communicate Strategically, Stony Brook University: Scientific Reasoning, Stanford Encyclopedia of Philosophy: Abduction, Model-Based Reasoning in Science and Technology, Scientific American: Your Scientific Reasoning Is More Flawed Than You Think, Collective Hedonism: on the blurred lines between heroic and mundane, How to Reject the Toxic Materialistic Way of Thinking. Long story short: We have no good answer to the problem of induction. A medical diagnosis is an application of abductive reasoning: given this set of symptoms, what is the diagnosis that would best explain most of them? 2. This is an example of the logical fallacy affirming the consequent (Just because all P are Q, that doesn’t mean all Q are P), P1: Tiger Woods is one of the greatest golfers of all time, P2: Tiger Woods has won over 15 major championships, C: Tiger Woods is the greatest athlete of all time.

P1: A Billionaire has more money than a homeless person, C: Jeff Bezos has more money than a homeless person. If one or more premises were removed from the argument, the argument would still stand. Inductive and deductive reasoning are both approaches that can be used to evaluate inferences. Inductive reasoning follow a flow from specific to general, deductive reasoning flows from general to specific. This difference between deductive and inductive reasoning is reflected in the terminology used to describe deductive and inductive arguments. Study on the go. If there is no theory yet, you cannot conduct deductive research.

That is, they move from a more general level to a more specific one. contrasts with inductive reasoning (bottom-up logic), and generally starts with one or more general statements or premises to reach a logical conclusion However, just because we’re not sure that inductive reasoning leads us to certain knowledge about reality, it’s not going to stop us from using it because it’s practical and useful, and it works more often than not.
