Hypotheses are based on theories.
If a hypothesis seems incorrect then a scientist knows that she has been mistaken about her understanding of the theory, and that's why she formed the wrong hypothesis to test. Or it might be that she has learned that there are new conditions under which the theory does not hold, and that the theory must be refined. Both of these are useful to scientists.
