content: Totally agree- but I know why people think it's a good idea: school.  School favors guessing and lazy certainty over honest ignorance, because the latter begets critical and independent thinking, which doesn't fit into the system.  Most people buy into it and by the time they are grown up they are still living out the teacher's pet archetype, where they get to pick a simple answer to a multiple choice question (e.g. dem or repub candidate) and then are rewarded and told that they are "right" and get a gold star from the media machine that is aligned to the answer they gave, and by all their friends.  Nothing is shunned more throughout school than plain ignorance, and most carry this into adulthood and the workplace.  Too bad, because openly admitting ignorance is the quickest way to learn, and also to not be made a fool of or manipulated like the broads in this video.
