I found empirical support for the idea that the Harry Potter series influenced the political values and perspectives of the generation that came of age with these books. Reading the books correlated with greater levels of acceptance for out-groups, higher political tolerance, less predisposition to authoritarianism, greater support for equality, and greater opposition to the use of violence and torture. As Harry Potter fans will have noted, these are major themes repeated throughout the series. These correlations remained significant even when applying more sophisticated statistical analyses – when controlling for, among other things, parental influence.
Totally fascinating research into how reading shapes political beliefs.
