One of the media's favorite news hooks is to cite a "scientific controversy." It's an attention grabber because most people believe that science is set in stone, and that it's one of the few sectors of public life that's opinion-free. Gary Herstein wrote a great post on the subject in July, and it's worth the full read. Snip:
"Real scientific controversies casually require decades to play themselves out, and MSM journalists generally have neither the time nor the training to follow such play with the kind of nuance required to accurately portray them."
