It's completely obvious that the doctor isn't going to really read the paper (he's too busy). You just present a paper and suddenly the doctor will trust you more. Literally it's deference to Authority being employed by the doctor here; nothing going on with rationality or logic.
Don't present a single logical argument to the doctor. If that argument, however logical, goes against traditional medical knowledge you will be dismissed. The key is to forget about logic and use an authoritative approach.
I'm betting the actual contents of those research papers don't even matter. You can print out a completely bogus study, just make sure it looks legit.
There has to be some degree of verification regardless of how complex the world is. At the very least he should read the paper. Because not doing so is hypocritical. Doctors treat patients as dimwitted idiots but suddenly the patient is smart because he has a paper? No, you can't make that judgement unless you read the paper.
What the mother did here was more rational and logical then every doctor in the department of UCLA. Think on that, then think about the amount of money UCLA charges patients and whether or not this sort of incompetency justifies this high level of monetary compensation.
I would say all people are irrational and biased. The issue is Doctors in general think they're better than everyone. They dismiss the fact that the biases and crazy ideas that effect all of humanity could effect them as well.
