I think there's more factors than that. Air traffic controllers are very overworked and they don't often cause collisions[1].

I think this part of the article is what the big problem is:

“Eighty percent of doctors don’t think probabilities apply to their patients,”

I've recently gone through 4 years of medical treatment, and it's still ongoing. Only to find out this week that I have Lyme disease. Given that the chances of getting Lyme where I live is relatively small, it was overlooked for many years. I even asked doctors to test for it, but they refused. Meaning I'm a direct example of doctors not considering non-regular cases. It cost me over $20,000 out of pocket. Not to mention the other things it cost me.

I don't know if its a form of arrogance or how they are trained or a combination of both. But can be life-destroying for patients to say the least. The leading cause of death in Lyme patients is suicide.
