I have a minor skin condition for which I semi-regularly take an oral medication which clears it up. I'll preface this by saying I don't think my family doctor is dumb and he's been my trusted doctor since I was born. I went in to see him a few years ago after some time off from taking the treatment, and he was like so what are you taking for this? I told him what I normally take (it should be on file but whatever), and he googled the medicine right in front of me and read one of the first pages summaries of the drug. Mentioned the risks that he was reading right off the site, and I'm like, yeah ok you've been giving me this for years. He's like are you sure you really want to take this though, here are the potential risks. I'm like, you're the fucking expert man how the fuck do I know, maybe we should do tests or something? You're the fucking doctor. Again, I've been taking this for years at your direction, so hook me the fuck up I guess?
Then like a year after that, I go in for more, and he's like oh wait there's a new one I want you to take instead that is potentially less harmful. I asked if it was more or less effective than the previous treatment, shrugged shoulders. Will the condition clear up permanently? Shrugged shoulders. They learn the accepted wisdom and repeat it, and I'd wager most of them don't really care to understand a lot of what goes on in the profession, when they can wear the white coat and point at peer reviewed studies and say well these guys say this works.
Another time many years ago I went to him because I was feeling pretty depressed and I was at the point where I wanted to know what my options were. I walked in and at the first word, he's like here you go take these pills. I was a little taken aback by this and decided not to take them (doing great now thanks for asking). I just feel like everyone is putting their trust in the guy above them without understanding anything. I can't stand drawn out internet arguments about this stuff anymore either because this is how everyone operates - it's googling battles and my trusted source can beat up your trusted source.
