While discussing epidemiology and drug policy with to an MD who works in the US federal government, he mentioned that he’s trained as a clinician, not in research.
I joked back that I wish most of the MDs who write for medical journals were clearer on the distinction, and he told the following quasi-joke:
Do you know what doctors mean when they say “In my clinical experience…” ? When a doctor says “in my clinical experience…” that means they’ve handled one case related to the matter. If they say “in my long clinical experience” that means two cases. And if a doctor says “In case, after case, after case…“, that means three cases total.
