Common sense is a gift that can be used or ignored.
You’re assuming I disagree with your view on over excessive testing. You are missing my point in this instance.
Show me where in the article it says the girl was anorexic. It doesn’t. It says the doctors assumed she was.
Suppose you have breathing problems which ordinarily you would expect a doctor to investigate. But suppose on the way to your exam you are in the presence of a smoker and your clothes smelled like smoke when you are in seeing him.
(I have a relative that every time I go to his house for more than 10 minutes I come out with my clothes strongly smelling of cigarette smoke).
So the doctor assumes you smoke, thus your breathing problem is no big deal, thus your lung cancer goes undetected until it metastasizes.
Another example:
15 years ago I went into A Fib (I didn’t know what I was experiencing). When I went to the cardiologist the first thing he asked was how much did I drink. According to him, 50% of the people who came in in A Fib had been on drinking binges. I said two or so beers every day. He took me at my word and I received treatment. He did not assume I lied and send me home with an admonition to stop going on drinking binges.
