Ethnomethodological studies of mediated interaction and mundane expertise

This paper introduces ethnomethodological studies of skill and reasoning in domains of mundane expertise. In particular, it focuses on reasoning in the game of checkers. Reasoning is generally considered to be a 'thing of its own kind', something universal that transcends the empirical situations to which it is applied. The game of checkers suggests something quite different: that reasoning is domain specific and that it belongs peculiarly to the practices from within which reasoning arises. Through the material on checkers, the paper illustrates ethnomethodological research as a 'tinkerer's craft' and attempts to show the continuing vitality of small-scale ethnomethodological studies for raising fundamental, foundationalissues of social inquiry.
