Medical diagnosis, widely understood to be an intellectually complex t
ask, is also shown as the product of a complex social process involvin
g individuals who vary in status and area of expertise. The credibilit
y of clinical information directly depends on the status and expertise
attributed to the patient and to various members of the hospital team
. The author reveals this social component by examining the discourse
that occurs as medical experts evaluate clinical evidence in order to
arrive at a satisfactory diagnosis.
