The things are supposed to happen "naturally" or they were not meant to happen. (Seems to me this is a consequence of believing in the supernatural, even if people are not conscious of it.)

I'm not sure about the connection with the supernatural here. I've always thought that acknowledging a need to consciously improve is just seen as something low-status. (This is frequently coupled with a belief that it isn't possible anyway, and being faulty plus attempting something impossible is kind of extra-low-status.)
