An instinct can also be a feeling that causes you to believe something, or do something, even though you have no specific reasons or facts to account for it.

By the way, the correct question is "What is the difference between the words 'impulse', 'instinct' and 'hunch'?"

Thanks for correcting my question. I heard that you use 'between' for comparing or talking about two things while 'among' is used for more than two. Could you tell me why my use of 'among' is wrong?

We divide things between/among two people.
We divide things between/among three or more people.

There are differences between/among two or more people.
