How much personal exposure have you had to journalists? They generally are smart enough that they could get a facile grasp on a technical issue in the limited time they have if they really wanted to, but it's rarely a wise use of their time. Human interest, nearest cliche, drama, all of these bring more eyeballs. High quality journalism will get you better quality (richer) attention but there are a lot more people who read US News, or the Sun, or Die Bild than read quality press.
tl;dr Journalists sell eyeballs, not truth
