hazarding uneducated guesses

The best we can ever do in any given situation is to make our best uneducated guess about the hows & whys & wherefores.  The info we have at hand might seem like a lot, but it's usually just a teensy bit of what could be learned.  And our personal filter always colors what little we do seem to grasp.  Uneducated guesses - that's the best we can ever do.
