A lot of medicine is pattern recognition. You recognize a specific set of symptoms and what it can be etc. Radiology is no different, you are right. But, to say that most radiologists are bad is just silliness. And, it doesn't make sense in the context of medicine and how it is practiced today. If a radiologist is bad, the patients treatment changes, and the patient will suffer, then you can easily note the mistake. Turn that around, a poor FM doc; which are basically FNP's but still better than FNP's, will be a referral monkey. Even in the ED, there is a wide range of skillset. I worked as a scribe, and doctors would talk behind their backs; saying so and so isn't good at procedures, orders too much etc.
