@ninokadic@philosophy@academicchatter i wonder how much of the co-authorship has to do with necessity of co-authorship (rather than choice) 1. less positions available for philosophers 2. increase in breadth/depth of fields of study 3. increase in education i.e. as higher number of postdocs, where, 60 years ago a postdoc was not as common to secure a faculty position.
i feel like looking at potential confounding factors would be best to get a good idea
