Hehe Journalists are like High School teachers in this country: most are not trained to be expert in anything but communicating something. What it is they're supposed to communicate, they don't really need to know themselves. The more people they succeed in communicating _something_ too, the more successful they are considered.
(my apologies to HS teachers reading this thread. There are some good ones; just not many of the ones who ever taught me, and those were ill considered by their peers.)
So a moron who can show a bloody leg to 200 million people is more successful than someone with brains whom half the audience doesn't have the intelligence or education to understand.
