My job for the last 12 years has been editing books and reports written by experts in various aspects of law, finance, strategy, data/research, the environment and fundraising (and more), and the one consistent thing I've noticed is my ability to identify what's unclear/doesn't make sense (where many others haven't noticed) and to get to the bottom of the issue, no matter the subject. If I need to become knowledgeable enough on a subject to rewrite a chapter or a book, I can do that within a few weeks or months (depending on the length) even if I have zero interest in the subject.
E.g., last year I learned the ins and outs of due diligence law (re nonprofits working with corporates) to rewrite two chapters on the subject
E.g. pretty much everyone is terrible at referencing: I check all references in authors' books/chapters and more than half of them turn out to be wrong/find the primary research and judge its validity
E.g. even in chapters written by academics and research experts, I've found a surprising number of errors
E.g. experts are often terrible at communicating in basic, easy-to-grasp terms what they want to say: there are scientists out there communicating good and helpful things, but only in a way that either only other scientists would understand or weirdly obsessive people like me who are willing to delve into the biology or biochemistry
