This last paragraph seems particularly relevant:
Importantly, Van Prooijen said his findings help make sense of why education can contribute to “a less paranoid society” even when conspiracy theories are not explicitly challenged. “By teaching children analytic thinking skills along with the insight that societal problems often have no simple solutions, by stimulating a sense of control, and by promoting a sense that one is a valued member of society, education is likely to install the mental tools that are needed to approach far-fetched conspiracy theories with a healthy dose of skepticism.”
