And this is why Hermione does not fit into Ravenclaw, since she lacks their creativity of thought. When you also add in her fearlessness and her strong convictions about right and wrong, which are inherently Gryffindor traits, then there was even less of a chance she'd end up wearing blue and bronze.
In one of the later books, Hermione even makes mention of this by stating that the Sorting Hat was heavily leaning toward placing her in Ravenclaw. In the end, the Sorting Hat firmly recognized her bold courage over her intellect and decided to place her in Gryffindor.
Ron Weasley
Being Harry Potter's best friend certainly needed heaps of bravery – hence the Sorting Hat not messing around in sorting Ron into Gryffindor, the house of his parents, brothers and sister. But the Hat specifically states that Gryffindors usually have 'daring, nerve and chivalry'.
Although Hermione was sorted into Gryffindor, the Sorting Hat considered Ravenclaw for her. However, despite her intelligence, her values weren't necessarily always aligned with Ravenclaw's. Hermione was more brave than witty, as shown in Harry Potter and the Sorcerer's Stone when the trio got trapped in Devil's Snare.
The only reason Hermione wasn't put in Slytherin is because she's muggleborn. Way to perpetuate Slytherin's elitist mentality, Sorting Hat… A singular trait isn't enough to place you in a house, no matter how dominant it is. Hermione is intelligent, but that doesn't automatically mean she's a Ravenclaw.
He actually asked the Sorting Hat to place him in Hufflepuff, as he was intimidated by Gryffindor's reputation for bravery, but the Sorting Hat didn't agree. They debated it for so long, that he was close to being what is known as a Hatstall, which is a term for any student whose Sorting takes longer than five minutes.
Her real parents were Daneel and Dean Novak, Pureblooded wizards. Turns out Daneel was Tom Riddles younger sister, Daneel Riddle. Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin.
She's seen as a bit absent-minded, is easily distracted, and is extremely eccentric in both her disposition and general outward appearance. But that's what makes her a perfect Ravenclaw. She loves learning, but unlike many of her housemates (or Hermione, for that matter), she can never know enough.
Because the sorting hat considers not the qualities one possesses, but the qualities one value. Dumbledore may be a brilliant wizard, but he valued bravery above everything else.
Poor Harry certainly had his fair share of it over the years, and no one inspired more survivor's guilt in him than Hufflepuff Cedric Diggory. We pose that Cedric's death is the main reason Harry never wanted to visit Hufflepuff.
The only quality she shares with Salazar Slytherin is being a dark wizard. Bellatrix actually belongs in Hufflepuff. She is fiercely loyal to Voldemort, standing by his side the entire time. She also waited for his return while stuck in Azkaban with the patience only a Hufflepuff could have.
Albus ended up in Slytherin because he couldn't stop thinking about ending up in Slytherin, and so the Sorting Hat couldn't grasp anything other than his thoughts about being in Slytherin.
Harry Potter battled with the Sorting Hat over his desperation not to be placed in Slytherin. Years later, his son Albus arrived at Hogwarts with similar preconceptions. Meanwhile, Neville Longbottom was so intimidated by Gryffindor that he nearly became a Hufflepuff.
He would have been more than welcome in Ravenclaw house. He was sorted into Slytherin because his mother was sorted there, and we all know the sorting hat takes your opinion into account. As a half blood, he was only exposed to the death eaters, and blood status seniority because he was in Slytherin house.
The pair were parted when the Sorting Hat placed Severus in Slytherin and Lily in Gryffindor, and while Lily thrived in her new, magical life, Snape was essentially placed in close quarters with the likes of Lucius Malfoy, Avery and Mulciber.
McGonagall was born a half-blood witch as her father was a Muggle and her mother a witch. McGonagall began her Hogwarts education at the age of eleven and was sorted into Gryffindor after being the longest ever Hatstall between Gryffindor and Ravenclaw.
He was a Gryffindor
Hagrid's Hogwarts house is never mentioned in the books, but, given his kindness, noble nature and bravery, it might not come as that much of a surprise that Hagrid was in Gryffindor.
Moaning Myrtle
Born in the late 1920s to Muggle parents, Myrtle Warren started her Hogwarts life in the early 1940s, where she was sorted into Ravenclaw. She had no friends, and was bullied relentlessly because of her glasses and acne. But she would soon have all of eternity to get her own back.
She was sorted into Slytherin House at Hogwarts School of Witchcraft and Wizardry and hated her time at the school due to never being given any positions of power. After her time at Hogwarts, Umbridge rose to prominent and influential positions in the Ministry of Magic in the Improper Use of Magic Office.
It's not in-canon, but I'm speculating that they originally kept Luna in the basement for ready access to keep Xenophilius under control. After Xenophilius was sent to Azkaban I think they discovered that Luna was helpful in keeping Ollivander alive.
In the Chamber itself, we see a large statue of a wizard, which Harry presumes is Salazar Slytherin. We also meet Tom Riddle, who is, as it turns out, the heir of Slytherin. Present only in spirit, he has all the same been controlling Ginny, and having her act as Slytherin's heir.
Harry is the Heir of Gryffindor (though his powers have been bound by his father when he was a baby), Neville is the Heir of Hufflepuff, Meghan (OFC, daughter of Sirius) is the Heir of Ravenclaw. Harry/Ginny, Ron/Hermione, Remus/Tonks. Sixth year. After a rare magical illness Harry becomes outstandingly powerful.
While it's true that Voldemort is a descendant of Salazar Slytherin, he is the “Heir of Slytherin” because he is a parselmouth and he figures out he needs to communicate with the basilisk to open the Chamber of Secrets. Tom Riddle, Jr simply appropriates the title “Heir of Slytherin” for himself.
