The article linked above talks above faulty thinking in assessments and ways to do better. Its a pretty good read.

Another EMS favorite: “overconfidence bias”—the tendency to believe we know more than we actually do. EMS training, even at the paramedic level, provides us with only a sliver of the knowledge of physicians, who spend many years in intense training for their practice.
The journal he made the references (listed at the bottom of the article) from is pretty good. The abstracts are available online which can give a good insight to what the article is about and the view point of the original author.
actually. that article was pretty good.. yes JEMS has a bad rap but if you automatically blow off every article from JEMS as bad with out even reading it you may miss out on some good information.
