According to John R. Lee, MD, of Sebastopol California, there are a number of reasons for this. " The first reason lies in the fact that the selection process of medical students depends on large part on college grades. Students get high grades when they simply repeat in their tests exactly what the teacher wants them to say. Students who question what they are being taught, on the other hand, usually do not get the higher grades. Medical schools, therefore, are filled with students who are good at adopting given 'wisdom', but not necessarily good at thinking and questioning, because they have learned to follow precepts handed to them by presumed authorities."

The second reason that accounts for the way many doctors think is that medical schools tend to be organized into organ-specific departments. " The idea of an underlying link between these different departmentalized diseases is nonexistent within this framework, " Dr Lee says
