He is on the editorial board of some 15 journals, and is the longest serving "Collaborating Editor" of Social Studies of Science. Scholarly interests Practices: Turner has published in the overlapping fields of sociology and philosophy, particularly on the notion of practices. In The Social Theory of Practices as well as in other writings Turner argues against collective concepts like culture: what we call culture (and similar concepts), he argues, needs to be understood in terms of the means of its transmission. There is no collective server by which it is simply downloaded and "shared". What we take as "collective" is really produced through experiences of interaction which are different and produce different results for different individuals but which also produce a rough uniformity through mechanisms of feedback rather than "sharing". He has extended this argument in various places, most recently in relation to the philosophical idea of "normativity" which he argues is an explanation of "facts" which are the product of an unnecessary and mystery-producing redescription motivated by an attempt to take back ground from social science explanation.
