"Being right is based on knowledge and experience is often provable.
Knowledge comes from the past, so it's safe. It is also out of date. It's the opposite of originality.
Experience is built from solutions to old situations and problems. The old situations are probably different from the present ones, so that the old solutions will have to be bent to fit new problems (and possibly fit badly). Also the likelihood is that, if you've got the expereince, you'll probably use it.
This is lazy.
Experience is the opposite of being creative. If you can prove you're right, you're set in concrete. You cannot move with the times or with other people.
Being right is also being boring. Your mind is closed. You are not open to new ideas. You are rooted in your own rightness, which is arrogant. Arrogance is a valuable tool, but only if used very sparingly.
Worst of all, being right has a tone of morality about it. To be anything else sounds weak or fallible, and people who are right would hate to be thought fallible.
So: it's wrong to be right, because people who are right are rooted in the past, rigid-minded, dull and smug.
There's no talking to them."
