It is not a very good question.
Take buying a car, you do all the research on them, you come down to Honda vs Toyota, pluses and minuses on both sides, you pick the Honda because you like it better. Simple example but true, with every thought you use both to come up with a answer.
Another example 2+2= * now you give the answer as 4, is it because you reason it out, or you said 4 because you gave or heard the answer before and they said "good Job" and made you feel good about yourself and you want to do it again?
Reason and emotion will always go hand in hand. You can?t separate the two.
How is this, i am guessing most people will pick Reason, one reason for that will be, because it sounds smarter, and people want to feel smarter. So they pick the option that will make them feel better about themselves and their appearance to their peers.
