Mundane Reasoning

Membership Categorization, Conversational Analysis

The existence within the everyday (mundane) world of the way in which we share conceptions of social facts is mundane reasoning. Commonsense reasoning is also referred to as mundane reasoning.

Commonsense reasoning is a term used by ethnomethodologists, derived from Alfred Schutz (1899-1959), referring to the practical or everyday reasoning used by members of society to create and sustain a sense of social reality as being objective, factual, predictable and external to themselves.

Since the objectivity of the world as a practical accomplishment is the focus of ethnomethodology this kind of reasoning is a primary topic of investigation.

Mundane reasoning by parallel constraint satisfaction - Mark Derthick, Publisher Carnegie Mellon University Pittsburgh.

Mundane Reasoning - Melvin Pollner - Philosophy of the Social Sciences.1974. Melvin Pollner examined the ways in which this reality – the ordinarily unquestioned conviction of “an ‘out there,’ ‘public’ or ‘objective’ world” - is produced and sustained in ordinary interaction.

This work on mundane reasoning is remarkable on several counts. First, Mel turned these issues from airy philosophical speculations to grounded empirical studies, examining the actual uses of mundane reason in an ordinary setting, a municipal traffic court. Mel showed how the very same problems in recognizing and sustaining a sense of an objective reality routinely arose and were handled in ordinary, everyday exchanges in traffic court through the processes of mundane reasoning.

Mel argued that mundane reason’s assumption of the objectivity of the world generated everyday puzzles or anomalies on the order of “how come he saw it and you did not?” If there is one real world available to all, how can two people see or experience it differently? But mundane reason also provided ways of resolving these nascent reality disjunctions while preserving the notion of one common real world; notably, by “discrediting one version as the product of a faulted or inadequate method of observing the world”. In an article published with Lynn Wikler in 1985, Mel provided a detailed case study of these processes of reality construction by analyzing how a family produced and sustained a version of their five year old daughter as of normal intelligence and verbal competence against clinical diagnoses of profound retardation.
