This troper's mother. Once claimed that he shouldn't go into engineering all because she claimed there are no jobs there. Her argument? She had a law degree and watches cable TV news (no actual statistics mind you, just a GutFeeling). That's all changed by now mind you, but still, a nasty case of DidNotDoTheResearch.

This troper knows several of these types. I never knew that AR-pattern rifles use a roller-block system...

This troper's roommate fits it quite well. He insists he remembers being born, among other things. And he definitely thinks that the possibility he only thinks he remembers this is silly; after all, isn't it more reasonable to think that he has a special mutation allowing him to remember before the neurons can even form the right connections?

This troper's father, when it comes to anything technological. Did you know that if you have a webcam connected to your computer at ''any time'', even if you unplug or disable it, teh haxxors can get into your computer ''and look out through your webcam''? And that putting your face on the internet - be it through a profile picture or vlogging or what have you - means ''they can find you''? (Still don't know who "they" are...)

This troper's mother barely knows how to uses a computer, but always tries to use jargon during any type of conversation. Even if she doesn't know what it means.

This troper's younger brother gets like this about certain subjects. Wouldn't be quiet so bad if he didn't laugh in this crazy-annoying voice at your "misinformation" and proceed to tell everyone nearby about it, while spewing his own false information, calling you a "child." Two cases this troper remembers was him laughing loudly at another student for mentioning that Merlin was an actual person, and when this troper told him to keep his skin hydrated after a sunburn. Good news was the troper's mother also informed him that yes, you need to keep your skin hydrated when burned; bad news was the troper had to listen to the goddamn laughter for five minutes!

Merlin wasn't an actual person. He is based on two other guys of which at least one really existed, but that's about it. That's like saying that Zapp Brannigan is a real person because he is based on William Shatner.

My sister. When confronted with a word neither she nor I knows, she will make up some BS definition of the word and adamantly state it as truth, no matter how much I tell her she's wrong. My mom will then correct her, and she will almost always say, "H-haha...fooled you."

This troper has someone in his college class who fits this to a tea. This particular student always acts like they are smarter than everyone else, but ends up making faulty statements ranging from 'all animals work together to survive' to 'Turkey has a drinking culture'. The funny side to this is that half the class accepts this as truth and adds on to that statement until a different student (always the same one too, who also never seems to talk outside of class) ends up correcting him. Neither student backs down though, and the professor generally lets both students feel that they are correct. The one exception to this rule was when KnowNothing made an assertion based on a play that Buddhism subtly encourages suicide and got into an arguement with the Loner. While the professor did not intervene then, he did chew out the KnowNothing when the former wrote his essay on that very topic and complained vocally about his grade. Crowning moment of Awesome for that class and was an entertaining moment to an otherwise boring course.

Turkey, the western half at least, does have a drinking culture. They're a secular country and don't have shari'a law in force, so people can drink if they want... (And they do!) Same goes for much of the rest of the Middle East (Outside Iran and the Arabian peninsula)

Subverted with a friend of this troper, I have a friend who appears to be constantly spewing bullshit whenever I'm talking about anything at all, the subversion is he's always somehow right. I wish he actually was lieing so I have a good reason to be annoyed at him.

Sounds like InsufferableGenius material to me.

This troper's mother. She never listen to other people on a subject she doesn't know about, and when she gets it wrong, she goes on NeverMyFault mode...or for him, just threaten to hit him. He hates her so much because of this.

I found it ironic that no one admits to being one themselves. I can be like this sometimes, and I know I've seen plenty of tropers act like this on the wiki...

Adding on, I used to role play with a 16 (at the time) year old girl who was like this because she got good grades. She was actually incredibly sheltered and naive (and if anyone told corrected her she'd whine), but her use of her self-insert OC (I wanted to call Mary Sue a couple of times but didn't) showed she deluded herself into pretending she was intelligent due to insecurities.

Seems to be played straight here. I don't know this girl, but how could you possibly know about someone's "insecurities" based on their writing, or that they're pretending to be intelligent instead of just being wrong? She could simply just be a bad writer, or someone who wanted to imagine herself alongside her favorite characters.

I've had a few *looks up* whatever. Anyways, I've had a few moments like this (More than I probably know in fact.) In between mixing up facts with other facts, misreading things, assuming too much, and other blunders I find myself paranoid that anything I say could very well make me this. (Being sure that I'm a genius and an incredible narcissism doesn't help.)

High school gifted programs are full of these, as this Troper can attest. It is impossible to argue with anyone because they all need to be right, all the time, to the point where she just smiles, nods, and snarks internally. She used to be one herself; she'd like to think she got better.

I try not to do this too often, but I do have my moments. Usually they involve me shooting my mouth off at someone who has political or religious opinions I strongly disagree with, especially if I haven't thought things out too well. It's not something I'm proud of, but (as someone else said) I'd like to think I've gotten better about it.

This troper has a friend who is such a KNKIA that he can often be used to judge the accuracy of a rumor: if he insists that it is true, you can be sure that it is not.

I've has been told in the past that I'm BrilliantButLazy. I personally believe I just have shades of this very trope.

While I do not come anywhere close to having traits defined by this trope, I did know one individual who does act like this. He was in my physics 20 and chemistry 30 class, and despite being a fair student, he had an unfortunate habit of correcting me whenever the occasion presented itself, except they backfired on him on every count. It was embarrassment from being counter-corrected by me that led to his attempts to surpass my performance in both classes, which ultimately failed anyways (I beat him by one percent in physics and eight in chemistry).

This troper can be really bad about this, although I've gotten better. Apparently, even though I don't remember this, in 2nd grade and presumably onwards I cried when I got answers wrong in class. I have a tendency to make broad sweeping generalizations, and even though I do know a fair bit, I am wrong often enough to stay at least somewhat humble. Of course, my friends have gotten used to taking what I say on face value, so that's no help!

This troper's mother tends to be one of these - she has this need to be right all the time, and the smartest in the room on any topic under the sun. This especially shows when it comes to talking about sexism, racism, homophobia ect. (subjects my brother and I are pretty passionate about) or subjects like drugs or tattoos. She isn't really that interested in prejudice, but when the subject comes up, she doesn't want to appear less knowledgeable or socially concious than me or my brother, and sort of winds up pretending she's already aware of and has thought about everything we're saying, or just spewing bullshit. When it comes to drugs or tattoos or [=STDs=], she basically assumes the worst in every aspect possible (''every'' drug is physically addictive, ''most'' tattoos get infected, things like that) and if I contradict her, she then assumes I know from personal experience. Which I ''really'' don't.

This troper has been made into the second half of this trope, without yet having been discovered as the first half, because of people around him who keep telling him he is some kind of genius or erudite, just because he has good memory for little known facts and curiosity for pieces of information most people don't bother knowing. Being painfully aware of this makes this troper extremely paranoid about the possibility of being wrong in public, which doesn't help with the social phobia. This troper, then, prefers to star spewing facts only after having assessed that nobody in the room is an expert on the field. And yes, this troper is ashamed of this.

My father often winds up being this. He goes on and on about how he ''thinks'' I should do my job, and it really, really gets on my nerves. We also tend to get into religious arguments from time to time (I'm a Seventh-day Adventist, and he's not a Christian) and he makes all sorts of ridiculous claims, both about church members and the faith itself, which I know for a fact he can't prove (and if I ask him to give me evidence of his claims, he takes up an attitude).

A colleague of mine has successfully convinced himself that flipping coins affects the probability of subsequent flips. He can provide a very detailed, internally consistent argument as well, incorrect though it is.

This troper has a classmate which is this trope. He is often insisting that he knows about every subject, but ends up saying loads of meaningless stuff.

My aunt is like this. She is such a strong case of this that she believes the reverse too: Anyone she sees not randomly spewing out information about some topic, she will believe them to be fools and treat them as such. A friend of my father was like this too, and her case led to the inevitable conclusion: She tried to show off obviously untrue statements about astronomy to someone she later found out is a postgraduate professor of astronomy.

@/FarseerLolotea has an acquaintance who is convinced of several "facts" that are either scientifically impossible or quantifiably incorrect. This woman has furthermore convinced her daughter of some of them.

This seems to be a theme amongst people who've taken a year or so of a foreign language and then believe themselves to be completely flawless. This Russian troper has had many occasions where she corrected someone's GratuitousRussian for bad spelling/grammar/general fail, only to have them come back with "NO, I'M A HIGH SCHOOL STUDENT TAKING RUSSIAN, I KNOW WHAT I'M TALKING ABOUT BETTER THAN A NATIVE SPEAKER."

This troper's dad doesn't like to be proven wrong at things. He once got on Facebook to look and see if our town's newspaper had a Facebook page. We do, and he kept wanting us to look at their friends list. Except that the paper didn't have any friends at that moment and he was pointing at the "Like" people. My brother and I kept telling him that that ''wasn't'' the friends list, and he eventually threatened to hit us. It's somewhat frustrating to live with him because of this trope and one of the reasons I don't like to ask for his help with something.

I zig zagged this trope. Before, my mother and classmates convinced my that I'm a freaking genius, which I then believed because I was, well, a fool. I started becoming a bookworm, and the "Pretentious InsufferableGenius" personality actually waned, becoming more and more humble. When I got depression, I claimed that "I know nothing", but is still considered as one of the biggest geniuses in our class, which of course was a bad thing because of the bullying. But the humility didn't end. Because of The Internet and reading about such things like Nietzsche and Hitler, I became a Pseudo-Insufferable Genius again, this time turned UpToEleven and in the form of a NietzscheWannabe, turning philosophical discussions into fiery rants and using the pretentious ornamental decorations of FauxlosophicNarration, SesquipedalianLoquaciousness and Lovecraftian speech to distinguish my own selfish ego from others, while also advocating a form of Social Darwinism where the government should be a technocratic BraveNewWorld and the lower ignorant masses should be kept in their filth so that they could be used for any form of {{manipulative bastard}}ry. I read about Socrates again, realized my mistake, and tries to know that I only know I know nothing, but this KnowNothingKnowItAll personality revealed itself to be an oedipal-like subconscious impulse focused on A Divine Genius Am I. In other words: Fluctuating.

This tropers brother in law tends to be a bit of this, though a nice guy he'll make statements about things and adimantly refuse to listen to any corrections which irritates this troper because this tropers something of a more authentic know it all and does know a lot of things but tries not to make statements that he doesn't know for a fact or will say, "Don't quote me on that, I'm not totally sure". One example that comes to mind was where he stated British Columbia, the province of Canada we live in, was a tropical rain forest and refused to hear the correction that essentially entailed this troper saying, "No, it is a temperate rain forest" since B.C. is in a temperate zone.

As an aside, from the same troper as the above, this troper's dad is very much a know it all who has bumped into many a KNKIA's due to his tendency to enjoy discussion or arguing with other over...well mostly anything because it 'can' be entertaining, he once told this troper of an arguement he got into with a KNKIA who'd chosen to hold up a customer service line by preaching a, "What is this world coming to" when he was getting refunded an item for more money than he paid for it in the first place. My father criticized him and the argument that ensued had the man backed into a corner upon which he said, "Well, why don't we take this outside, then?". This troper's dad claims his reply was simply, "The last refuge of a man who knows he's in the wrong"- because apparently physical violence turns even two wrongs into a right.

I tend to go there, due to unfortunate early experiences in school. (Was precocious enough to occasionally know more than my grade-school teachers in some subjects.) And as people seem to automatically assume I know what I'm talking about, I've learned to stay out of conversations altogether.

For about two years I had an odd inversion of this trope happen to me. Despite not having a real girlfriend (one that I actually can call a girlfriend) until grade 12, people constantly asked for love advice. I tried to invoke this trope on myself, but they really didn't care. Funny thing was, it actually ''worked'', at least according to them. Incidentally after I had gotten a girlfriend, they all stopped asking.

This troper had a roommate like this once. Despite her being a music major, the roommate would constantly ask her questions like, "Did YOU know this Beethoven symphony? I bet you haven't heard of it, it's not very popular." Er, yes, she DID know the symphony, and had in fact thoroughly studied, analysed, and discussed it in the course of her classes. It got worse when the roommate starting taking an introductory university music class. (Didn't you know? An introductory university class automatically makes you an expert in all things!)

My parents do this all the time, in different ways. My dad will just make up answers if he doesn't know the answer, but he always sounds perfectly sincere. This was particularly bad when I was in 7th grade, studying a list of words for the Science Olympiad event "Picture This" (basically Pictionary, focusing on science terms). He told me that "focii" were two separate things you focus on at once (they're two points around which an ellipse is built), and that "egestion" could be drawn as vomiting (he had the right idea but it...comes out the other end). I wasn't very happy when I looked the words up myself. My mom will also read an article about something and then say stuff as if she's the leading expert on it; with how misleading science reporting can get, this is often bad. Though to be fair, I tend to do this a lot too. And so do my brothers and my sister. I guess it runs in the family.

I did a Bastion of Twilight run in WoW the other day, and this Druid kept bugging the Disc Priest about his spec, claiming that Smite Atonement is the only viable Disc healing spec. The Priest and I (I'm also a Priest for my main, but he's Holy) both patiently explained that while Smite is viable, a Greater Heal focused spec is perfectly viable too. The Druid kept arguing, even up to Cho'Gall, when the Disc Priest was outhealing the Resto Shaman by a few thousand hps (I was Shadow for this fight), and while we didn't down Cho'gall, the Disc Priests mana never dropped below 40%, despite the Druid saying that it's impossible for a Greater Heal spec to be sustainable. It was very annoying.

This is one of this troper's worse habits. He's genuinely clever- and a liar with a warped memory. At least it's (usually) humorous. ("Not only are bananas slightly radioactive due to containing unstable potassium isotopes, they used to have gills before they were removed by selective breeding in the sixth century B.C.!"

ANY idiot who tells you that "games are good for nothing" is this trope. They can teach you various things. Metal Gear Solid 2 is used for "meme teaching", Garry's Mod is used for physics (read articles), and I'm playing Half-Life, it's sequels, and any other game with a language option to get a better grasp on my Spanish. (In addition to taking classes)

Also, I admit to having been this trope before, but now I know better. One of my friends, however is still this trope. He thinks he can get good at martial arts (Like Jiu Jitsu or Muay Thai) WITHOUT an instructor if he just pays careful attention and practices the stuff at every opportunity.

In which you are an expert.

That internet forum on which you were.

Without being connected to "were", "on" loses meaning in that sentence. It's a phrasal verb there, not a preposition.
