At some point the “academic smarts” have to demonstrate success, otherwise people will rightfully discard them. Decades of constant failure from supposedly elite people in every possible field have lead to a reaction where people just don’t trust them no matter what they claim. Name your issue, and I guarantee someone with very good credentials who was very confident in their advocacy is responsible for its current state.
The problem isn’t that the “proles” are stupid, but rather that the educated aren’t nearly as smart as they think they are. Nearly every person I know who has poor critical thinking skills and accepts the first thing they hear without question is college educated, and there are many conspiracy theories commonly believed by educated people.
