I was recently reading a social science paper (in a prestigious journal) on my country of birth. I noticed the author made a major factual innacuracy on which most of their analysis is premised. While it's easy to see how the author might've gotten confused, as the mistake is one a casual observer would make, the facts are quite different from how they're being portrayed. To give a hypothetical example, it's something like saying the Queen (substantially) controls the UK government and then writing a refutation of non-constitutional monarchy. Should I say something? I am thinking of emailing the author, but I'm not sure how to proceed. I am also applying to grad school at their university, so I don't want to burn any bridges before I even start applying.
