Theory - unambiguous description of a method of prediction. The prediction
doesn't have to be contiguous with current states.

Terry
Why don't you be clearer about what you mean by theory. 

In the sciences - natural and artificial - theories generalize available
records of past observations to future observations either of the same kind
like in prediction of voting outcomes or following existing patterns like in
extrapolations of existing trends. 

design by my definition violates what occurs naturally, i.e. Without
interventions by human agents (designers). For example, a theory that
predicts the the outcome of elections assumes that a sample of voters are
representative grows of trees or the movement of plants around the sun is
based on the conviction that observed pattern continue to persist into the
future - unless designers interfere with the underlying commonalities of
present and future observations. 

You say that a predvyij
