One piece of advice—one that I haven’t seen mentioned—immediately follows from this: The way to improve your writing is to practice writing. Serious prose writers write every day. Academic social scientists who want to write well should do the same, and this especially holds when carrying heavy teaching, administering, and research loads. Because no one generates enough primary research to fill a solid hour of writing every day, it means writing for other audiences. Book reviews, referee reports, recommendation letters, blog posts, it probably doesn’t really matter, so long as the focus is on the act of writing.
That’s Cornell’s Tom Pepinsky, adding his grain of salt to a discussion of academic writing that was sparked by Stephen Walt in a post for Foreign Policy.
