It's not just people in the media who don't know the difference between a double-blind study and anecdotal evidence!
However it also annoys me that many scientists seem prepared to totally dismiss anecdotal evidence without ever testing it out.
For example, many doctors simply laughed at using acupuncture for decades before any of them actually got around to finding out whether or not it actually works. NICE now recommends it for consideration as a possible way of treating certain types of headaches.
