Not necessarily, but it always seems counterintuitive to do so. To me, anyway.
For example, my experience of people trying to write scifi when they don't read the genre (or worse, tell me they actively dislike it) is that they tend to have very generic ideas, because they're generally less aware of what's already been done, covered, and expertly explored.
