A professor at Ulster University claims there are four types of Harry Potter readers, one for each of the four houses at Hogwarts

His research found ‘Hufflepuff’ readers take the tales at a slow, steady and systematic pace and enjoy re-reading the books over and over.

“People will look back and say ‘Why did we ever read this stuff?’”
‘Gryffindor’ readers are eager and energetic and will devour the latest Potter book in one sitting, but quickly move on to new things.

‘Ravenclaws’ are subversive and take the stories with a pinch of salt, while ‘Slytherin’ readers are not fussed about the books.

They prefer the films but pretend to have read the books when it suits them.
