Here is a truly masterful piece of academic writing that for some reason I came across earlier today.
From the title, right through to the conclusions there is much for us to learn here.
It doesn't matter which academic discipline you follow, read this paper from the BMJ.
Although the article at first glance appears flippant there is a serious message here about the use of evidence based research.
As I read the paper my eye was drawn to an entry in the side bar of the BMJ site, offering a view of the citation map. I've not seen one of these before. Its a neat idea.
