Agreed. Furthermore, I would say that's true of most things requiring a lot of experience

The people who come up with the methodologies initially are probably the people who have needed them the most / longest. They had experience that informed the development of the methodologies not methodologies that substituted for experience. Therefore, these methodologies are more successful given people who could figure out a similar methodology independently and could conceivably be worse than nothing for people who couldn't.
