A hunch can be trusted if it can be explained.
Though intuition is not infallible, it can be a useful speculative tool, if handled with care and skepticism.
If you are hit by strong hunch – put it to the test. Trust it only if you can explained it. That is only if you can identify within your mind a stored body of information out of which that hunch must reasonably be supposed to have arisen.
Be wary of any intuition that seems to promise some outcome you want badly.
