I've been told the "free marketplace of ideas" will sort these sort of problems out any day now. Unfortunately the FMoI has zero capacity to handle Brandolini's Law and has shown itself to be so useless it can't even set Flat Earth believers straight.

smart people are just as susceptible

More so as you mentioned above. I know plenty of people who aren't that smart who know they aren't that smart and are humble and don't presume outside of their expertise. But there's a certain class of "educated" folk who think that because of their education they know everything. Let me say that troubleshooting software issues with doctors is absolutely the last thing you want to do. Please let me talk to the secretary who claims she knows nothing about computers.
