One of my favorite things to do as a huge Harry Potter nerd is to ask which house people are in or try to determine if for myself. I personally am a nice, yet cunning Slytherin (yes we do we exist!), my genius brother is a Ravenclaw and my sister is as Hufflepuff as they come.
Considering I've been forced to live without a Sorting Hat of my very own, Muggles like myself have to resort to online quizzes or guessing a person's house based on distinct personality traits. Clearly not ideal, but what other options do we have?
While some of my friends are unmistakably Gryffindors, Slytherins, Ravenclaws, or Hufflepuffs, others have some characteristics from a blend of houses. So how will we ever get to the bottom of who truly belongs where?
Dawwy from Reddit came up with a pretty clever theory (perhaps he is a Ravenclaw?) discussing and explaining the reasoning behind each house and which traits pertain to the four.
The Main Three and the Houses and our Protagonists
The first part of the theory refers to Harry, Ron, and Hermione. Although they are all in Gryffindor, Dawwy touches upon the fact that they exude traits pertaining to the other three houses.
Hermione is a genius and has an intense passion for knowledge, therefore containing the renowned Ravenclaw quality of intellect.
Although most people would agree that Ron gives off a bit of a Huffelpuff vibe, Ron actually has many Slytherin traits.
He is ambitious, wants to be praised, he often has extreme bouts of jealousy, acts out when his pride is attacked, and isn't as loyal to his friends as he should be, which are some of the more unfortunate qualities found in Slytherin.
Lastly, we have Harry. Although he had the choice to either be in Slytherin or Gryffindor, and chose Gryffindor, he contains the essence of Hufflepuff in quite a few of his actions and personality.
For example, Harry is very loyal to his friends and tends to be the peacemaker when Ron and Hermione are in a tiff. His biggest desire is to belong and have a family. He is tolerant and kind, which is evident in the way he treats and accepts the strange and lovely Luna Lovegood. He also helped Cedric Diggory in Goblet of Fire during the Triwizard Tournament, which showcases that he is a very fair person, another attribute pertaining to the Hufflepuff house.
Houses of Families, "The Gryffindor Exclusion Theory"
Magical families have a knack for sticking together in sorting. Take the Weasleys for example, who all belong to Gryffindor house. The Malfoys, on the other hand, are all Slytherins.
So then how do we explain outliers like Sirius Black, those from predominantly Slytherin blood who end up in Gryffindor? This brings us to the classic nature versus nurture discussion, or what Dawwy calls "The Gryffindor Exclusion Theory."
Gryffindor is a special house and, as demonstrated above with Harry, Ron, and Hermione, Gryffindors contain other traits that pertain to the other three houses, but the traits of bravery and strong will are the most prominent.
Gryffindor appears to be more connected with your traits rather than how or in which family you grew up, and therefore the gene of the Gryffindor can be carried on and appear later, as opposed to the other houses.
The Three Brothers Fable, "The Gryffindor Gene"
In The Deathly Hallows, Dumbledore gives Hermione a book titled The Tales of Beedle the Bard, which contains the story that was supposedly about the three Peverell brothers who escaped Death. Hermione shares this story with Harry.
In return, Death became angry and lured them into trickery by congratulating the three with a gift. Two of the brothers took the Elder Wand and the Resurrection Stone, which ultimately led them to their deaths. The third chose the Invisibility Cloak, which protected him from Death until he finally hit an old age and was ready to pass on.
According to Dawwy, the three brothers represented in the film also end up giving life to the three houses in Hogwarts: Slytherin, Hufflepuff, and Ravenclaw.
Slytherin descends from the power-hungry wizard who possessed the Elder Wand. The wizard craving mastery and knowledge of Death, who asked for the Resurrection Stone, would be the start of Ravenclaw. And finally, the last brother who was more humble and asked for the Invisibility Cloak, represents Hufflepuff.
Most of the wizard families are descendants of these three brothers. Dawwy figures that the Weaselys, Malfoys, and Slytherins all descend from the brother who desired the Elder Wand. The Diggorys and the Hufflepuffs can be traced up to the brother who asked for the Invisibility Cloak.
The Gryffindor gene does appear in the Weasleys, perhaps from Molly, as Arthur is distantly related to the Malfoys. Sirius Black also somehow got the Gryffindor gene, as he is a black sheep amongst a family filled with Slytherins. Gryffindor obviously contains the gene, as he compliments the other three houses, therefore creating the fourth house of students containing what we call the "Gryffindor Gene."
A Little Spin, Free Will and Fate
ojajaja made an excellent point in this Reddit thread, claiming that a bit of the theory goes against one of the most important points Rowling makes in the books, which is the ability of free will rather than having a secure fate. This can be seen in characters such as Snape, who was brave and selfless even though he was in Slytherin, and Peter Pettigrew, a Gryffindor who was still the epitome of a traitorous coward.
This theory seems possible, but perhaps we will never know. The only person who has all the answers is the goddess known as J.K. Rowling, who is thankfully continuing to release material and facts about the wizarding world.
