Intuition

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.

Never confuse a hunch with a hope.
