"The systems of stereotypes may be the core of our personal tradition, the defenses of our position in society. They are an ordered, more or less consistent picture of the world.…They may not be a complete picture…but they are a picture of a possible world to which we are adapted. In that world people and things have their well-known places, and do certain expected things. We feel at home there. We fit in. We are members. We know the way around. There we find the charm of the familiar, the normal, , the dependable; its grooves and shapes are where we are accustomed to find them. …it fits as snugly as an old shoe.
“No wonder…that any disturbance of the stereotypes seems like an attack upon the foundations of the universe. It is an attack upon the foundations of our universe, and, where big things are at stake, we do not readily admit that there is any distinction between our universe and the universe.”
Walter Lippmann, Public Opinion (1922)
