Worst And/Or Craziest Misconceptions
You run into a lot of scientific and medical misconceptions (particularly when you have a blog with a working e-mail address plastered on the front page of it!) There are plenty of harmless ones that are easy to correct, and at the other end of the scale there are major weltanschauung problems (like the "drug companies don't want to find a cure for cancer because it would put them out of business" line). Those involve what Kingsley Amis called "permanent tendencies of the heart and mind", and I'm not sure if they can be fixed at all.
I got to thinking about this subject again after seeing this item, which is pointing out to physicians that a meaningful number of their patients may well opt out of surgery for cancer because they believe that cancer spreads when exposed to air. This turns out to be a common enough belief that it's addressed on many medical sites. It's not one that I'd heard before, and I thought I'd heard quite a few of these.
So, in the spirit of discussions like this one, I'll toss out these questions: what's the farthest-from-reality misconception about medical/pharma topics you've encountered? And what widespread one do you think does the most harm? (Warning about that link: it goes to a hugely long thread, which will soak up your time as you continue running into yet-more-ridiculous beliefs that people have expressed).
My own candidates: the weirdest one I've encountered might be the person who still believed in spontaneous generation (that old bread just sort of "turned into" living mold, etc.). And the most harmful one, from a drug research perspective, might well be the constellation of "the government does all drug research" beliefs, or the one mentioned above, the "drug companies don't want to cure X" one, which shades into the "drug companies have a cure for X but they don't want to release it" belief.
