When you want to find out how things really are, you need to apply logic, reason, evidence, and counter-evidence.
When you want to find out how to live your life, it may pay out to develop compassion and empathy, and follow your heart.
However, it is probably not very useful to try and solve questions about objective reality by looking into your intuition; and it might prove a little difficult to base your life's dreams, who to fall in love with, what job is best suited for you, only on hard evidence.
Hard evidence certainly plays a part in that, but it's not the whole deal. Interestingly, this does not work the other way around: Your feelings can never tell you the speed of light, the date of your mother's birthday, or whether god exists.
