It is interesting about the 'bias' of doctors towards their own experience. I guess my point is that statistically this kind of 'bias' towards the most common syndromes is a net positive for society; it's an allocation of resources thing--we don't have so many doctors that we can afford them all to be running off on weird tangents investigating possible rare diseases that aren't there...
Again, sucks if you do happen to be the one in X thousand that has the rare disease. Am I being too utilitarian?
Regarding tone: apologies; I agree it was an overly flippant comment. It was more a reaction to some of the other doctor bashing that was going on in this thread that fails to see the woods for the trees. I see now that that wasn't your intention...
