Do you ever get paid for any of them?
Do you ever refuse any? How do you decide what to refuse?
#1 has found that she’s getting more and more all the time. One of her senior mentors has told her she needs to start saying no to the ones from journals she’s never heard of. So she’s done that once so far. She did say yes to a recent journal she’s never heard of, but only because the editor is someone she has heard of, and in her field it’s good to do favors for people. #1 does probably ~20 referee reports per year, including grants, and that’s probably too much. One journal pays $100/report. Grants and books pay $100 to $500 per report, or sometimes just a free copy of the book.
