Backwards induction is one of the most powerful and underutilized scientific techniques. It is incredibly common that you can't prove some proposition A is true, but you can always assume that it is true and determine what that implies. By following the chain of implications you can sometimes make predictions that are provable, which then supports your hypothesis.
