Deductive reasoning is studied in logic, psychology, and the cognitive sciences. [3] [1] Some theorists emphasize in their definition the difference between these fields. On this view, psychology studies deductive reasoning as an empirical mental process, i.e. what happens when humans engage in reasoning.
Deductive inference is monotonic: if a conclusion is reached on the basis of a certain set of premises, then that conclusion still holds if more premises are added. By contrast, everyday reasoning is mostly non-monotonic because it involves risk: we jump to conclusions from deductively insufficient premises.
Philosophy of psychology also closely monitors contemporary work conducted in cognitive neuroscience, cognitive psychology, and artificial intelligence, for example questioning whether psychological phenomena can be explained using the methods of neuroscience, evolutionary theory, and computational modeling, respectively.
A priori ('from the earlier') and a posteriori ('from the later') are Latin phrases used in philosophy to distinguish types of knowledge, justification, or argument by their reliance on experience. A priori knowledge is independent from any experience. Examples include mathematics, [i] tautologies and deduction from pure reason.

In this sense, it includes questions about the role of rationality, critical thinking, and the psychology of argumentation. [34] Another characterization identifies informal logic with the study of non-deductive arguments. In this way, it contrasts with deductive reasoning examined by formal logic. [35]
It overlaps with psychology, philosophy, linguistics, cognitive science, artificial intelligence, logic, and probability theory. Psychological experiments on how humans and other animals reason have been carried out for over 100 years. An enduring question is whether or not people have the capacity to be rational.
Neopositivists led emergence of the philosophy subdiscipline philosophy of science, researching such questions and aspects of scientific theory and knowledge. [24] Scientific realism takes scientific theory's statements at face value , thus accorded either falsity or truth—probable or approximate or actual. [ 17 ]
