Kyle Hill has written an interesting article on JREF, about human information processing. It's a bit of a difficult read, but overall quite plausible. Hill argues that most of us most of the time use a quick, heuristic mode of judging information, as opposed to systematic thinking. Heuristics may be valid, but are often invalid.
The last paragraph, about increasing scientific literacy and critical thinking, had the following question, motivated no doubt by an heuristic of his own: "Why are 9/11 Truthers so closed off from other sources of information?" This question, of course, is patently false and is based on his own biases regarding the 9/11 Truth movement.
The title of the article is An Introduction to Human Information Processing (Part 1)
