The ability of deductive reasoning is an important aspect of intelligence and many tests of intelligence include problems that call for deductive inferences. [1] Because of this relation to intelligence, deduction is highly relevant to psychology and the cognitive sciences. [ 5 ]
Non-deductive reasoning is an important form of logical reasoning besides deductive reasoning. It happens in the form of inferences drawn from premises to reach and support a conclusion, just like its deductive counterpart. The hallmark of non-deductive reasoning is that this support is fallible.
Deductive reasoning is a basic form of valid reasoning, commencing with a general statement or hypothesis, then examines the possibilities to reach a specific, logical conclusion’. [10] This scientific method utilises deductions, to test hypotheses and theories, to predict if possible observations were correct. [11]
A logical rule that justifies the transition from a set of premises to a conclusion, forming the basis of deductive reasoning. rule of replacement A rule in formal logic allowing for the substitution of equivalent expressions within logical proofs, maintaining the validity of the argument.
The syllogism is a form of deductive reasoning in which two statements reach a logical conclusion. With this reasoning, one statement could be "Every A is B" and another could be "This C is A". Those two statements could then lead to the conclusion that "This C is B". These types of syllogisms are used to test deductive reasoning to ensure ...
