Thanks for the link, Lateralus - interesting points. I do tend to agree with most of it, the only real exception being the statement about people not being capable of scientifically studying something that they care about. I do think that it is more difficult than optimal, but it can be done - especially over a longer term (as the interviewer mentions).
The process of science is probably the best thing we have right now to try and cut through some of the mistakes that worldview gives us... but for most people, in most situations, there just isn't a surplus of time, effort, and personal vulnerability to bring that to the forefront. Huddling with a social group is comfortable, easy, and seldom entails as much personal risk as even *trying* to see things objectively.
