Who does the educating and who decides what that education should be? No doubt the most extreme across the spectrums will eagerly volunteer to do both while insisting that they're the moderate center.
Well, for example, schools? We already teach children history, basic statistics, media literacy, basic epistemology, etc.
That does not mean that schools teach kids what to think. Rather, we teach kids how to think, and what the common pitfalls are.
The problem is that this means that a bad education leaves you vulnerable to manipulation. That, and the fact that it takes 10-20 years for the effect to reach society.
