We can point fingers at these doctors. If I didn't work at Hopkins, perhaps I would go on at greater length here about what their systematic deviation from scientific practice means for patients' lives.
The more you think about it, though, the more you realize that we are all implicated, in greater or lesser measure, in similar activities. Our motives are perhaps not as venal; the connection to coal company's payment not as relevant. But inconsistency of diagnostic practice, dealing out judgments, interpretations, and prescriptions not based on the best scientific evidence, and depending on pseudoscientific "lore" under the influence of economic factors are all widespread in today's medicine.
In fact, if you consider how ubiquitous in today's medicine is the use of non-evidence-based treatment, you understand that this pneumoconiosis story is only the tip of a very black iceberg indeed.
