Quote from Stephen Covey in "Seven Habits of Highly Effective People" that was brought up in a seminar I attended today:
"Each of us tends to think we see things as they are, that we are objective. But this is not the case. We see the world, not as it is, but as we are -- or, as we are conditioned to see it. When we open our mouths to describe what we see, we in effect describe ourselves, our perceptions, our paradigms. When other people disagree with us, we immediately think something is wrong with them."
I almost started a thread on the comment, but it applies pretty well here. By the way, I'm a 1 too!
PS: Just because I posted that quote does not mean I entirely 100% agree with it, but I do think there's a lot of truth in thinking that we all think we are less biased by our own experiences than we really are. I'm sure somebody out there might be a 1, but most of us that think we're a 2 are probably a 4, 5 turns into 7, etc. I think I'm a 3-4 trying to be realistic, which probably makes me a 5-6
