When I review a thematic collection of academic papers, there are several possible outcomes. The entire collection is relevant and I blog each one in turn. A few papers aren’t relevant, but I blog the entire collection for completeness’ sake. Only a few papers are relevant and I only blog those. Or it turns out that none of the papers are relevant and I move on without blogging. Well, it turns out there’s a fifth option: none of the papers are relevant and I want to blog about that to let people know not to bother.
