TheHarry Potterfranchise is beloved by fans who found their beloved of reading and fantasy through the series . But while the books and movies might be magical , they are not always coherent . Over the years , eagle - eyed fans have been able to distinguish several times when the series split and turn away its own rule .

Many   of these plot holes and logic gap were compose byRanker , with fans voting on their top ten . range from minor inconsistency in spell vagabond to major plot point , here are the fans ' top representative whenHarry Potterignored its own logic .

Wands Choose The Wizard… When Convenient

Fans learn early on on that wand choose their magician , but in the final installation of the series , they also discover that sceptre ' allegiances can be won . This is specially authoritative with the Elder Wand . While Voldemort assume that the sceptre ’s allegiance must be won by killing the premature owner , Harry wins out by bring out that disarming the previous proprietor is sufficient , which makes him the Elder Wand ’s rightful proprietor .

However , disarming spells are incredibly vulgar in the series , exercise regularly in schoolhouse , and used in battle . No sceptre changed allegiances in that time , so it seems like a pretty major secret plan mess to change wand lore so late in the biz , disregarding the numerous disarming that take place in the earlier Good Book .

Dennis Creevey Visits Hogsmeade Early

In his third class , Harry was given the opportunity to chitchat Hogsmeade , but was unable to attend due to his aunt and uncle refusing to sign on the permit slip .   However , Dennis Creevey was capable to attend the interest meeting for Dumbledore ’s Army   at the Hog ’s Head at only twelve years old .

Fans can appreciate the level of devotedness that the Creevey brothers have for Harry , but he should n’t have been able to get into Hogsmeade in the first place . That being tell , the age restriction for bring down Hogsmeade are just one of manythings about   Hogsmeade village that do n’t make sense .

Hermione Forgets Having Cast A Memory Charm

Fans are stick in to memory spell inChamber of Secrets , where Gilderoy Lockhart practice   them to make realised wizards and crone forget their own achievement so he can take credit for them . The spell then is largely forgotten about until the concluding script , when Hermione require to do a computer memory spell on Death Eaters that catch them in their travel .

Hermione performs the spell before commenting that she does n’t know if it ’s been successful since she has never performed a computer storage patch before . However , before they began their travel , she revealed that she had used magic to make her parent draw a blank her for their own safety . While the process might work differently on wizards than muggles , that ’s emphatically a contradiction and would have been an easy one to touch on .

The Rules Of Summoning Things Change

make a consistent magic system can be difficult as a author , but break your own principle , and writers can be sure their fans will acknowledge . InDeathly Hallows , Harry , Ron , and Hermione fight to get food for themselves because the rally piece is unable to   channelize living being .

However , this negate events both before and after this Koran . When Harry is practicing the spell inGoblet of Fire , he utilise Neville ’s toad Trevor as a practice dummy . moreover , inFantastic animal : The Crimes of Grindelwald , Newt Scamander summons a niffler . So it would seem that " Accio"is utterly open of summoning living beings .

Wizards Are Unrealistically Ignorant

The Wizarding World is shown to be thoroughly unplug from Muggle Britain , but that note does n’t make very much sentiency , dedicate the importance of muggles the inheritance of wizardkind . The huge legal age of wiz appear to be half - rip or muggle - born , which intend they have frequent verbatim tangency with Muggles . While there may be several pureblood families , authorities like Sirius and Arthur Weasley claim even they have muggle branches in their family trees .

So if so many family have muggle parents and relatives , how did wizards get so ignorant about the rest period of the globe ? Yes , their instruction ignores important theme like history and civics , but most wizards have at least one substructure in the muggle humanity . Yet wizards are so incognizant of the muggle world that they seem to be in a never-ending land of confused awe , making it so that wizards likeArthur would fall in love with even the most basic muggle invention .

Hogwarts’s Student Population Doesn’t Add Up

fan have long seek to envision out exactly how enrollment numbers ferment at Hogwarts , and while there are some attempted explanations , the general consensus is that the numbers do n’t add up . It ’s been explained that Hogwarts generally has about 1,000 students in abidance at a time , but only 40 young student go into per year , adding up to 280 factorization in all seven years .

The best account for this is that Harry ’s multiplication is small than those before it because so many citizenry died in the First Wizarding War , but it still does n’t make common sense with the various figures the fan are given . Beyond that , it makes it even more unmanageable to determine what proportion of British and Irish citizens are in reality genius .

Dumbledore Forgets Slytherins Live In The Dungeons

" Troll in the dungeons ! " outcry Professor Quirrell . Dumbledore responds by ordering all of the students to their dorms , where they will presumably be safer . But that does n’t actually make sensation for all of the students . While the Gryffindor and Ravenclaw students may be safe in their column , and the Hufflepuffs in their dorms by the kitchen , the Slytherins are being assure to lead toward the supposed danger .

Perhaps J.K. Rowling simply had n’t decided on the location of the Slytherin dorms yet , but by the sentence the film come out at least , someone should have observe that the Slytherin students were being directed toward their dorms in the dungeon . Whilesome Slytherins lean to be cowardlyand others incline toward bravery , none of the students were equipped to fight an escaped troll .

Everyone Ignores Dumbledore’s Portrait

Photographs and portraits have personality and life in theHarry Potterworld , with portraiture able to talk , move , and remember their original lives . In effect , portraits of someone who once lived seem to be an file name extension of the life , or at least of the personality , of the theme .

Despite this fact , Dumbledore ’s portrayal is rarely consider . ThisHarry Potterplot holecould be explained away by the fact that it would be difficult to get access to the Headmaster ’s Office , but it seems unmated that nobody even reckon the possibility . There were many things that Dumbledore never explain to the Golden Trio , but that could have change if they consult his portrait .

erotic love potion manipulate the thoughts and actions of their issue , frame them wholly in the thrall of the potion ’s owner . This is comparable to the Imperius Curse , which is so criminal that it can send its user to Azkaban . Because of these similarities , love potions theoretically ought to be illegal as well , because they take aside the agency of their study .

or else , making love potions are available enough that Hogwarts students have access to them . Furthermore , scholar are taught about Amortentia , the most powerful love potion , in their classes . The availability and legality of these mind - altering substance make no horse sense .

Unforgivable Curses Don’t Have Traces

InThe Deathly Hallows , the Death Eaters put a trace on the Christian Bible " Voldemort " so they can immediately find the citizenry who are using the word . This is because the only the great unwashed bold enough to use his name are members of the Order of the Pheonix , who are currently in hiding . This results in Harry , Ron , and Hermione being enamour and brought to Malfoy Manor .

It seems like a very effective spell , which led fans to wonder why it was not used for other purposes , specifically for the Unforgivable Curses — Imperio , Crucio , Avada Kedavra . Characters seem to be able-bodied to use the   Unforgivable Curses without any consequences ,   including Hogwarts student , but theoretically , the Ministry should be able to put a hint spell on the words that would allow them to at once appear and arrest the castor .
