Harry Potter was a massive part of the childhoods of millions of people. Even if you’re not part of the cult following, it’s unlikely you’ve been able to avoid the franchise completely. As it turns out, growing up with Harry Potter might have made you a better person. According to one study, published in the Journal of Applied Social Psychology, people who are emotionally attached to Harry Potter are less likely to be prejudiced against minority groups. There are a lot of different groups in the books, and the over-arching theme is to be kind to others, regardless of how different they are.
