What does wallace mean when he refers to the “natural, hard-wired default-setting” of himself and others (para. 3)? to what extent do you think that most of us are “deeply and literally self-centered”?

All of us are a product of the culture we are raised in, the rules and regulations that we must follow and the spoken and unspoken world views that are passed on. We see the world from our perspective and our reality, we cannot help it, it is the filter we look at life through. Sometimes without even knowing how prejudiced we are, we form our opinions from the experiences we have had and what we have watched as we were growing up. Everything comes from a place deep within us that helps us make sense of the world and the people in it.

Yellow versus red is not a receptor pair according to the opponent process theory.
