> true things are far less engaging
This is an over-generalization so I don't think your premise completely stands. Some truths are very engaging, and support large communities of people working together to explore them.
I would put forth that the systems design challenge has to start with the human mind. People need to be taught proper grammar, logic, and rhetoric to reason properly and be able to express and debate what is true and what is false. Getting to the truth is often difficult, but a critical thinker can quickly sort through bad information, because it's full of contradictions and fallacies.
However, the "system" doesn't seem to actually want too many critical thinkers, because that would make it more difficult to wield power over its population. Cognitive ability only needs to be trained up to a certain point where individuals become useful corporate inputs, so there's an incentive for conformity to outweigh critical thinking and even creativity. Therefore, I don't think a top-down approach e.g. federal education reform, etc. would actually work.
What might work is organizing a more bottom-up approach of building peer education systems. If you'll permit me to use Star Wars parlance, imagine 1,000 Jedi academies forming and coordinating at higher levels where possible. These academies could take many shapes and sizes, and some current examples include Khan Academy, Ad Astra Academy, Acton Academy, or even homeschool cooperatives.
