Via Making Light, we find this nearly perfect encapsulation of modern American non-think. The author explains:

I wrote these principles after reflecting on the content of contemporary newspapers and broadcast media and why that content disquieted me. I saw that I was not disturbed so much by what was written or said as I was by what is not. The tacit assumptions underlying most popular content reflect a worldview that is orthogonal to reality in many ways. By reflecting this skewed weltanschauung, the media reinforces and propagates it.

I call this worldview the American Cargo Cult, after the real New Guinea cargo cults that arose after the second world war. There are four main points, each of which has several elaborating assumptions. I really do think that most Americans believe these things at a deep level, and that these misbeliefs constantly underlie bad arguments in public debate.

I. Ignorance is innocence

Complicated explanations are suspect

Certainty is strength, doubt is weakness

Admitting alternatives is undermining one’s own belief.

Changing one’s mind means one has wasted the time spent holding the prior opinion.

Your opinion matters as much as anyone else’s

When a person has studied a topic, he has no more real knowledge than you do, just a hidden agenda.

Hey, I said it was probably true, not likely to cause you to think kindly on your fellow man.
