I don’t pretend to know how to accomplish this. I may be completely wrong here, but two things that have to go:

• Religious thought (“faithbrain” or the Peter Pan-esque belief that things are true because you believe they are true, despite a lack of evidentiary or even argumentative support, despite overwhelming evidence to the contrary)
• Social media bubbles (billionaires controlling the content people see, creating bubbles of “information” that skew the public in their favor)

There’s almost certainly more to do as well, but those things stand out to me. Also, it seems hard to believe that we could make any progress on these fronts given the current situation.
