The pandemic was an interesting case study in this. In the sense that although the alternative medicine people who started writing about covid after the pandemic started were generally giving terrible advice, the alternative medicine people who were writing about how to survive a novel coronavirus epidemic before December 2019 were generally much more accurate than the mainstream medical people who only started learning about coronaviruses after the pandemic started. It turns out, being genuinely interested in something when there is zero money to be made is a much better predictor of success than having formal training and insider status.
