There are "experts" on religion too, but why conflate fiction with reality? If Zach or X/Gordo were to tell me "x and y are the best lifts to build strength," would I be even close to a position to argue? No, that would be ridiculous as the evidence there are clear, but here we do it.
The two fields in which everyone thinks they know best is economics and medicine, but at least with economics you only have to hear about it every 4 years.
But the fallacy is in thinking that the voice in the media is that of the best and brightest. Just look at Google for reference do you think your queries are objectively triaged to get you the most pertinent results? I'm afraid you can't defer responsability simply because there is no credibility imo
This is understandable. However if an individual or group of individuals are decorated experts in a field with years of experience, why should I assume that I could know more after reading some studies or articles over a few days? To me this places someone like the Head of Thoracic Surgery at New York-Presbyterian on the same level as some random housewife down the street peddling detox teas and essential oils because she's a #momblogger and therefore knows what's best for her kids.
Social media bubbles and search engine algorithms can be talked about for days, they are designed to generate clicks and keep people scrolling. Look out for improvements in machine learning and deep fakes in the future.
Generative adversarial networks can already create some extremely realistic versions of almost anything, combine it all and you have potential for some really big problems. I said it before and to me this only gets reinforced by the day, fake news and the immediate distrust of official guidance/information is the greatest threat to this country going forward. But this is probably off topic anyway.
Go to a mechanic and not like what they said about your car? You get a second opinion. Dentist said you need 14 teeth removed? Second opinion. Doctor recommended open-heart surgery for some sniffles? Second opinion. But those second opinions are still going to be from someone else considered an expert in their field, no?
