why noble prize in literature only go to controversial writers?

The Nobel Prize for literature goes to authors who are innovative and thought provoking. Anything that is unlike what has gone before and that provokes people to think is a sure thing to be controversial - some people don't like anything that is new and different and exposes them to different ideas, and quite a few people do not like to think. If that is what you are like, maybe you should try to develop more acceptance of new ideas and new thoughts. It doesn't mean you have to accept the ideas or thoughts, but it would be better to be able to appreciate new ideas and ways of looking at things, even if you do not agree.

Because controversial writers write about new things and ideas rather than the same boring stuff that we always read about.

Borges is the guy I see fairly regularly stated in discussions of who were given gypped. yet when you're searching for most well-liked, that's gotta be Shakespeare. fool develop into lifeless till now they even began giving 'em out. undesirable occupation flow.

Because they had the audacity to write what others knew but would not say.

Because they right about what they see and think not what someone else tells them they should think and believe.
