Reminds me of this oddity: https://rarediseases.org/rare-diseases/jumping-frenchmen-of-...
Are there such things as mimetic diseases? We have definitely seen that alarmingly insane quasi-cults like Qanon or flat Earth can spread entirely via social media, so that isn’t too far away. The jump would be to something not requiring conscious thought or belief at all, something that fully bypasses the neocortex.
If that is actually possible I can see a future where everyone runs smart content filters (maybe AI powered) and curated whitelists before viewing things. Maybe there could be mental techniques for handling “cognitive hazards” that could be learned too. I feel like some mystical traditions have inklings of that like “visualize a white light around you” or “as I walk through the valley of the shadow of death, I will fear no evil.” Maybe that stuff fires up some anti-malware in your brain.
