Suppose that an authoritarian government decides to embark on a program of curricular reform, with the explicit goal of indoctrinating the nation's high school students. Suppose that it wants to change the curriculum to teach students that their government is good and trustworthy, that their system is democratic and committed to the rule of law, and that free markets are a big problem.

Will such a government succeed? Or will high school students simply roll their eyes?

Questions of this kind have long been debated, but without the benefit of reliable evidence. New research, from Davide Cantoni of the University of Munich and several co-authors, shows that recent curricular reforms in China, explicitly designed to transform students' political views, have mostly worked.
