The May Day story is that research shows Harry Potter readers become more tolerant toward minority groups:

Research published this week in the Journal of Applied Social Psychology found that kids who read J.K. Rowling’s wildly popular wizarding series are more likely to reduce their prejudices toward minority groups, reports Pacific Standard. The researchers from the University of Modena and Reggio Emilia in Italy noted that the books provide plenty of examples of bigotry, on which children can then form an opinion. From Harry’s defense of “mudbloods” like his friend Hermione, to Voldemort’s obsession with “pure-blood” witches and wizards, kids were able to recognize the unfairness in these instances and subsequently attach them to real-world examples of prejudice.

Tomorrow, May 2, we’ll be celebrating the anniversary of the Battle of Hogwarts –

I wonder what odds we'd get on the royal baby being born tomorrow and called Victoria?
