I'm not sure I'm making my point clear, so I'll try a different explanation: I feel that it is important that this page makes clear the difference between what the book actually says, and what people (hopefully reliable sources)say it means. Interpretations should not be mixed in with the synopsis or character profiles in such a way that they cannot be told apart. Even what Kesey himself said later about the book should be clearly differentiated from what the book itself actually says. 
In regard to wether I think the lifeguard has brain damage: The book certainly doesn't say so as it does in the case of Pete Bancini, so why leave the reader of this article the impression that it does? What would be wrong with just explaining that he's got cleatmarks on his forehead, and letting the reader reach his or her own conclusion? 
I am also well aware that I can edit the article, but I decided not to because I thought that some guy might object because he thought the things I changed were blatantly obvious. I just left these observations here for anyone who actually cares enough about the quality of this article to try and make the changes, and make them stick. Frankly, I don't.
