One of the reasons people might be fallible, why we might fail to do what we try to do isignorance, that we have a limited understanding of the laws of the world - the physical laws that govern the world and of all the particulars of the world upon which those laws work. And then there's ineptitude, meaning that the knowledge is available, but individuals fail to apply it correctly. The third source is "necessary fallibility." That is, we're never going to be omniscient, there is some knowledge that we will simply never achieve, and there are limits to what we will be able to do.

Culture matters. Of course, if physicians are rewarded or penalized for their service and results, the culture will change. But the key values we doctors are being pressed to embrace are humility, teamwork, and discipline.

We look for medicine to be an orderly field of knowledge and procedure. But it is not. It is an imperfect science, an enterprise of constantly changing knowledge, uncertain information, fallible individuals, and at the same time lives on the line. There is science in what we do, yes, but also habit, intuition, and sometimes plain old guessing. The gap between what we know and what we aim for persists. And this gap complicates everything we do.

Go back to the '30s, '40s, '50s, and it was the discovery of heroic interventions, the ability to cure people with penicillin or do an operation to stop disease that was what saved the day. Primary care physicians couldn't do all that much that really demonstrated a difference. The people who control and work with you to control your blood pressure, they're not rewarded for doing that or to be innovative about doing that. So, the result is half of Americans have uncontrolled high blood pressure, despite seeing clinicians.

If the conversation people think is coming is the 'death panel' conversation, that's a total failure.

In psychology, there's something called the broken-leg problem. A statistical formula may be highly successful in predicting whether or not a person will go to a movie in the next week. But someone who knows that this person is laid up with a broken leg will beat the formula. No formula can take into account the infinite range of such exceptional events.

Just look at the list of who the lowest-paid people are. Pediatricians are at the bottom. You would also look at internists. You would look at psychiatrists. You would look at family physicians, HIV specialists. People who take care of chronic illnesses by seeing people carefully over time, those are the people who get the least money. The people who have the most are people like orthopedic surgeons, interventional cardiologists. And my point isn't that there is something wrong with heroism.
