One's outlook is one's tendency to view the positive or negative aspects of people, things or situations.

Optimists tend to focus primarily on positive traits or possibilities, and pessimists tend to focus primarily on negative ones.

Regardless of their general outlook, most people seem to be predisposed to view with favor those individuals, groups or causes with which they sympathize, and seem predisposed to view with disfavor those of which they disapprove. They will sometimes even discount or ignore facts that are contrary to their chosen prejudices.
