Critical Realism

Critical realism theory states that the theory of knowledge, or epistemology, is different form a theory of being, or ontology. There is a reality which exists independent of its human conception. Critical realists believe that there are unobservable events which cause the observable ones; as such, the social world can be understood only if people understand the structures that generate such unobservable events. This is important in the experimental context, because it allows the scientist to distinguish between the event and what causes it. According to this theory, an individual conducting an experiment creates the conditions necessary for the experiment (observable event), but the results are caused by the underlying laws and mechanisms (unobservable events). The critical side of this theory arises from the identification of epistemic fallacy – the idea of analyzing ontological statements in terms of epistemological statements. Epistemic fallacy is caused by a failure to recognize a difference between ontology and epistemology. The realism side of the theory focuses on the existence of real mechanisms which shape events.
