I wonder about stuff like i. Scientists know best. and what people like Popper would or could or might or should or ought to say about it. As opposed to 'better' (followed by "than" -- as McEvoy writes above), 'best' calls for a different expansion ("if you happen to see the best girl in the world") since 'best than' sounds ungrammatical (I'm not sure whether what's grammatically unsound is logically unsound, too.
