Most theories' predictions are not open ended. It's possible to exhaustively search the prediction space to falsify them (up to an experimental standard that you need to agree on). I'm by far not an expert on super-symmetry but from what I've seen the prediction space of the most common SUSY models is getting continuously boxed in.
