The order of co-authors on an academic article or scientific paper are most often arranged either alphabetically or by the amount of their respective contributions to the paper. (See here, for example.) Why not instead arrange co-authors randomly or, better yet, by each author’s degree of belief in the results of the paper? As it happens, this latter option is what Andy Clark and David Chalmers chose for their “Extended Mind” paper, which was published in the journal Analysis, 58:1 (Jan., 1998), pp. 7-19.
