A sort of myopia seems to be rife through all the specialist fields - STEM, medicine, law, and politics all host individuals with a nasty combination of elitism and borderline-religious opinions. Whether or not they've actually studied the subject is irrelevant - everyone from the least educated bumpkin to the foremost authority may speak on it, and everyone else will take their opinions with a grain of salt and continue with their existing ideology, rather than try to dissect the logic.

Worse yet, it's possible for people to study the subject and still exhibit strong myopic symptoms. This is the origin of cargo-cult programming(to name one example).
