Well, I'm thinking in terms of internal mental constructs, not
  methodologies. Humans have a need for certainty and an ability
  to anticipate the future. Awkwardness and uncertainty is
  something we tend to rebel against, although it seems to be a
  part of the human condition.

  As a science, religions generally do a terrible job, woefully
  unsuited, although when performing at their best, they can be
  functionally adequate for psychology, anthropology and
  transmitters of enculturated values.
  As a religion, the sciences are becoming less terrible at it,
  although modern science advocates have a bit of an Evangelical
  bend to it, not having quite reached the maturity of ancient
  councils of Orthodoxy. In short, I don't think the sciences are
  quite ready to lead societies in quite the way that religions
  have in the past, although the sciences make excellent advisers.
  Still, I hope for a better alternative for religions or politics
  to lead nations into the future and look forward to the sciences
  maturing enough in their cooperation to afford them leadership
  roles in future societies.

  Although honestly, I think as head-of-state, I'd prefer a
  Librarian.
