Should you crowdsource your medical problems?

As a physician, I'm tempted to just respond, "No." But, of course, I'm biased and that isn't very useful.

The problem here is that "the plural of 'anecdote' is not data." Many people will tell you things like, "My Uncle had that, and it was X."

That said, despite the title, the article ultimately comes to the tame conclusion that expert consensus (particularly when it's based on a review of the available literature) is usually the best choice. Surprise.
