Short for perquisite. A casual or secondary benefit.
I hate being wrong. Probably no one likes it very much. I know that being wrong is part of the scientific process and that many scientists delight in being wrong. I can relate to that. I tend to love new discoveries. But new discoveries also tend to be something I’ve intentionally questioned, perhaps even knew I did not know. I get frustrated when I discover that something I was absolutely certain was true simply is not so.
