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 ]
Deductive reasoning is the reasoning of proof, or logical implication. It is the logic used in mathematics and other axiomatic systems such as formal logic. In a deductive system, there will be axioms (postulates) which are not proven. Indeed, they cannot be proven without circularity.
Reason is the capacity of consciously applying logic by drawing valid conclusions from new or existing information, with the aim of seeking the truth. [1] It is associated with such characteristically human activities as philosophy, religion, science, language, mathematics, and art, and is normally considered to be a distinguishing ability possessed by humans.
A Syllogistic Reasoning Task was created from a study performed by Morsanyi, Kinga, Handley, and Simon that examined the intuitive contributions to reasoning. They used this test to assess why "syllogistic reasoning performance is based on an interplay between a conscious and effortful evaluation of logicality and an intuitive appreciation of ...
Other forms of reasoning are sometimes also taken to be part of logic, such as inductive reasoning and abductive reasoning, which are forms of reasoning that are not purely deductive, but include material inference. Similarly, it is important to distinguish deductive validity and inductive validity (called "strength").
Deductive reasoning is the building of knowledge based on what has been shown to be true before. It requires the assumption of fact established prior, and, given the truth of the assumptions, a valid deduction guarantees the truth of the conclusion. Inductive reasoning builds knowledge not from established truth, but from a body of observations.

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.
