Can "quarantining" reduce the transmission of misinformation? Could we eliminate misinformation (intelligent design, climate denial, flat-earth theory, anti-vax propaganda, etc.) from the academy and deplatform it off of social media, and thereby protect the general public against "outbreaks" such as the 2016 election, Charlottesville, or the January 6 US Capitol Riots?
Another way to frame inoculation against conspiracy theories is "teaching critical thinking skills," which would be easier if a certain party in the US (the GOP) had not been working overtime to reduce budgets for education and sow discord in the academy for the last 40 years. Maybe we should stop giving their propaganda oxygen (quarantine) so that our educational institutions can function properly and constituents of our society can build antibodies (improve critical thinking skills) in our population.
Giving vaccines to people whose immune system has been primed to fail hardly seems like a logical course of action.
