Friend in SoCal recently called his primary care physician to ask about COVID testing because he and his wife had some possible symptoms (persistent cough). The doctor prescribed him a steroidal inhaler (he's had asthma before) and told him not to worry about it, but that symptoms persisted more than a week he could do an in person consult after he got back from vacation in Cabo.

They got tested and quarantined anyway... and came up negative, but are still changing PCP.

I was seeing a specialist once who was being shadowed by two med students on rotation, and the doctor started talking about chemtrails. The look on the med students' faces when he started going into that...

Med school requires good analytical smarts and an excellent ability to retain information, but I'm quite convinced at this point that raw analyical ability has almost nothing to do with the ability to think critically to avoid insane beliefs. It's just not something that humans come built-in with.

Easy to explain: being a doctor means understanding the dirty insides of profession thus know it is mostly bs. So naturally they don't trust it. Just like developers who do outsourcing, never do their own products because they know it's bs, and priests usually don't believe in God because they know dirty insides of the Church. In general, it is very hard to sell stuff if you buy into your own bs. Many otherwise great people failed for that, like Hitler - he lost because he started to believe his own propaganda.
