Yes, but inflation simply means you re-set expectations. I admit that, if I'm looking for a new book and I see that it's rating average is under about 3.8, I start to wonder what's wrong with it. Of course, I like plenty of books with a lower average rating, but that does give me my first impression. (It reminds me of when I was requesting a house on Airbnb and the owner writes "what's with the 4.9/5 rating you have? There's got to be a story about that." It turned out anything below a 5 set off his red flags.)
