Inductive arguments are considered valid when there is no other reason to believe one of the premises than to believe the conclusion.

What Is Deductive Reasoning?
Deductive reasoning is the process by which something is determined, based on pre-existing and accepted facts (or premises). When using deductive reasoning, a person selects the single best outcome or solution to a problem, supporting their choice with knowledge that already exists and has been determined to be true. Deductive reasoning is used in all sorts of situations, from day-to-day decisions in contemporary life to large-scale ones like those in policymaking or governmental settings.

What is a syllogism?
A syllogism is a type of deductive reasoning that follows a specific pattern. This pattern contains two premises and a conclusion. The first premise is a general statement, and the second premise is more specific. These two premises help create the conclusion. However, both premises need to be true statements in order for the conclusion to also be true.
What is conditional reasoning?
Conditional reasoning, on the other hand, uses "if...then" statements to make an argument grounded in deductive reasoning. In this context, an antecedent (the "if") is in relationship with a consequent (the "then"). In this context, an argument is valid when all of its components parts are true, and their outcome must also be true. An argument is invalid when its component parts are true, but the outcome can be false. If there is any chance of the outcome being false, then the argument is invalid.
Why is deductive reasoning important?
Deductive reasoning is used in the workplace for problem solving, as well as when organizing daily tasks and workflow . When problem solving, deductive reasoning allows co-workers to prioritize tasks or identify a solution as quickly as possible. For example, if it is an accepted fact on a team of editors that a manuscript is due on Friday, both the writers and illustrators are experiencing delays, but the writers always meet their deadlines without outside pressure, then the editorial team knows that they need to focus on supporting the illustrators.

What is deductive reasoning?

Also called "deductive logic," this act uses a logical premise to reach a logical conclusion. Deductive reasoning is often referred to as "top-down reasoning." If something is assumed to be true and another thing relates to the first assumption, then the original truth must also hold true for the second thing.
What is the first assumption in deductive reasoning?
Initial assumption. Deductive reasoning begins with an assumption. This assumption is usually a generalized statement that if something is true, then it must be true in all cases. Second premise. A second premise is made in relation to the first assumption. If the first statement is true, then the second related statement must also be true.
