It’s because humans naturally want to avoid unpleasant work, and public schools teach us that learning is hard and work for some reason, rather than something fun. For instance, I used to read for fun an unbelievable amount, but then I was forced to do book reports with a required list of books to “prove” I was reading them, and it was just absolutely no fun at all. Why not have a discussion about it and the teacher can check the spark notes? This changes at community college back to learning is fun, but just years of being told to do busywork and be a drone kills learning for a lot of people I feel.
