OA Self-Archiving Mandates and "Sitting Pretty"

"Sitting Pretty" may be one of the factors behind author passivity about self-archiving spontaneously, unmandated. I would say that tothe extent that it may also be enough to induce some "good authors" not to comply with self-archiving mandates, then that's fine. The research world is still incomparably better off with OA to all research except the research of these particularly pretty-sitting "good authors." What percentage do you think they constitute of all research -- or even of all "good research" worldwide...?
