->'''The Dragonborn''': Surely there's more you can tell me.\\
'''Master Arngeir''': There is indeed much that we know that you do not. That does not mean that you are ready to understand it.
-->-- ''VideoGame/TheElderScrollsVSkyrim''

Commonly uttered phrase by powerful -- often SufficientlyAdvanced -- beings when lesser lifeforms (like our heroes) ask for assistance or [[LowCultureHighTech technical support]]. Oftentimes, the heroes get a hold of the information or gear for themselves, and the point is proven or refuted. (If the hero keeps insisting for an answer, they may get an ArmorPiercingResponse, which may prove that they're indeed not ready.)

In other situations, this can be a line uttered by either TheMentor or the BigBad. In the former case, he is telling our young hero not to be brash and preparation is very important (though the hero will rarely listen). In the latter case, it is used as a rather [[LargeHam hammy]] [[TrashTalk taunt]].

Compare to FigureItOutYourself, TheWorldIsNotReady. [[JustForPun Not to be said to]] [[Memes/{{Nintendo}} Nintendo]].

* Cobalion, Terrakion, and Virizion say this to Keldeo in ''Anime/PokemonKyuremVSTheSwordOfJustice'' about it battling Kyurem. It tried anyway and [[CurbStompBattle got pummeled]], then ran away when [[HumanPopsicle its mentors were frozen]].
* In ''Anime/DragonBall'', Master Roshi panics when Yamcha and Krillin first attempt the kamehameha wave, fearing that they'd die if they released that much energy at once. {{Subverted|Trope}} when both of them [[StrongAsTheyNeedToBe pull it off flawlessly]].
--> '''Roshi:''' Rash child! The kamehameha wave is a dangerous weapon! You're not ready to use it!
* ''Manga/PingPong'': A variation is uttered by Kong during his first match with Peco (albeit internally):
-->'''Kong:''' ''Nothing'' about you is good enough!
* In ''Manga/OnePiece'', when [[{{Determinator}} Luffy]] tries to go up against all three [[AuthorityEqualsAsskicking admirals]] at Marineford, he gets hit with this. ''Hard.''
-->'''Admiral Akainu''': If nothing else, I praise your tenacity.\\
'''Admiral Aokiji''': But you're not ready for this stage yet.\\
'''Admiral Kizaru''': There's no way you can beat us, you know?
** Luffy actually seems to listen to this and realized his crew is not strong enough to survive New World. So via a secret message orders them to train for the next two years.

[[folder:Comic Books]]
* Upheld with the Watchers of the [[Franchise/MarvelUniverse Marvel Universe]] who originally shared their scientific knowledge with a primitive alien race. The alien race advanced to interstellar levels only to be obliterated after challenging a much more advanced civilization race to war. These events traumatized the Watchers into being non-interventionists.
* Upheld in Grimjack where some space aliens who were trying to dissect and understand a time travel watch accidentally obliterated one-quarter of a galaxy in the process.

[[folder:Fan Works]]
* ''Ghosts of the Past'', sequel to ''Fanfic/ChildOfTheStorm'', has [[spoiler: Bucky Barnes]] very bluntly deliver a speech along these lines to Ron (and to Hermione) after the two of them insist on coming with Harry to deal with vampires of [[spoiler: the Grey Court]]. It's not so much a matter of raw power - they're both powerful enough - but the fact that they're not trained, and they don't have the necessary combat experience in supernatural combat ops (while Harry a) has been trained, b) has got the experience, c) has far more raw power to bring to bear). At best, they'd be TheLoad, at worst, they'd be a corpse in short order - vampires are incredibly fast, strong, and vicious, and smart enough to recognise the threat of a wand. Hermione reluctantly accepts the explanation and asks if there's any other way they can help. Ron needs a little more convincing.
* In ''Fanfic/SoulEaterTroubledSouls'', the main part of Kidís [[ShadowArchetype shadowís]] argument is that it claims Kid is unfit to succeed his fatherís place as guardian and ruler of the world as a Grim Reaper. Not everyone will agree with his beliefs, the shadow using Kidís symmetry obsession as the basis, stating he is far too unique. It also claims he simply isnít strong enough to combat any of the potential threats.
* In ''Fanfic/TheWitchOfTheEverfree'', Celestia repeatedly telling Sunset Shimmer that she wasn't ready was one of the things which initially drove them apart; it didn't stop Sunset from continuing to research the mirror and alicornhood on her own, but it ''did'' cause her to become increasingly resentful of Celestia, as well as leading her to incidentally read some books on dark magic in the process of her research.
* ''Fanfic/HarryPotterAndTheMethodsOfRationality'': Harry says this word for word to Draco in order to keep Draco from learning too much science before he's ready for it--specifically the part about disproving Draco's racism, which he's built his entire personality around. Draco actually accepts this explanation without complaint; moving too fast in magic can be ''extremely'' dangerous, so Draco's father taught him to take warnings like that seriously. Draco actually ends up mad at Harry when Harry thinks Draco is ready for something but actually isn't.
* In ''Fanfic/PokemonResetBloodlines'', Red decides he'll try to find as many Mega-capable Pokémon as he can to boost his chances in the Pokémon League. However, he runs into Kalos Elite Four member Siebold, who realizes what he's up to, but points out to him that there's something he struggles with and no matter if he finds Pokémon and compatible stones, he won't be able to master Mega Evolution without it.


* ''Film/{{Sphere}}''. A depressing thought to Norman.
-->'''Beth:''' What's the matter, Norman?
-->'''Norman:''' It's a little hard to let go of. Something that could've been... this gift? The power to make your dreams come true. We're given the greatest gift in the history of mankind. We're given this magic ball. And it says "lmagine what you will and you can have it." That's an extraordinary gift, but we're so primitive we... we manifested the worst in us, because what we have inside us... is what we have inside of us, instead of the best of us. What does that say?
-->'''Harry:''' We weren't ready, Norman.
-->'''Normal:''' We have what's called an imagination. I mean, look what we're capable of. We can... ''(sighs)'' We're not ready.
* Uttered by the OldMaster towards his pupil in almost ''every martial arts film ever''.
** Usually in reference to some DangerousForbiddenTechnique.
* ''Franchise/StarWars'':
** In ''Film/TheEmpireStrikesBack'', Yoda informs Luke of this when he goes to face Vader on Cloud City.
** Played even more straight with Anakin's accession to Jedi Master in ''Film/RevengeOfTheSith''. Mace Windu knows a thing or two about ready, and Anakin is not ready.
* At the end of ''Film/{{Gremlins}}'', Mr. Wing shows up to claim Gizmo and berates the Peltzers for not following the rules of proper Mogwai care and states "You are not ready!" When he sees how much Gizmo has come to care for Billy, Mr. Wing decided Billy may be ready "one day".
* This is the attitude of the Autobots towards technology sharing with humans in the ''Film/TransformersFilmSeries''. They won't give us weapons to fight Decepticons with because they know we'll end up using them to kill each other, and they don't give us non-weapons technology because [[HumansAreWarriors they know we'd find a way to weaponize it]].
-->'''Optimus Prime:''' We've seen your human capacity for war... we believe it would only make things worse.
** In other words, exactly what the Autobots and Decepticons have been doing to each other for the last several million years? (Actually, this is sort of the point. Optimus likes humanity and does ''not'' want them ending up in a repeat performance of that).
** Optimus himself has admitted the above as when one Autobot says that we (Humans) are a violent race, Optimus points out the fact that they're NotSoDifferent.
** In the sequels it turns out that the Autobots ''are'' sharing minor technologies and fighting techniques with the humans in order to combat the Decepticons, [[UngratefulBastard and the bureaucrats are complaining that they're not sharing enough]]. After the Decepticons are taken care of humanity turns their new weapons on the Autobots, just proving Optimus completely right.
* ''Film/MortalKombat'' had Raiden tell Liu Kang he wasn't ready to face Shang Tsung. Which is quite weird, because he tells him he is ready, near the end, although we don't see anything changing in Liu Kang's character nor does he learn any new skills.
** It's implied that Liu not being ready was less about skills and more about being hung up on his brother's death.
* In ''Film/MysteryMen'' the Sphinx tells the others they are not ready to confront the BigBad because they need training (and {{Ice Cream Koan}}s.)

* This trope may have originated (in ScienceFiction, at least) with Creator/EEDocSmith's ''Literature/{{Lensman}}'' series back in the late 1930s. In that series, the rise of humanity and most other intelligent life in the Milky Way galaxy is part of a master plan by the [[SufficientlyAdvancedAlien Arisians]], who are about one step short of EnergyBeings. The goal of the plan is the eventual overthrow of the (quite nasty) Eddorians. However, at almost every step in the process the Arisians keep the ultimate goal a secret from humanity and its allies, and avoid making their own immense power obvious to them, for fear of "creating an inferiority complex" among the species they have raised to deal with the problem. In other words, YouAreNotReady.
* The excuse used by all of Creator/BruceCoville's aliens for why they don't swoop down and end all disease and strife on Earth. His last few books just had them as merchants who wanted stuff in return -- they got peanut butter and ketchup.
* In Creator/IainBanks' novella ''The State of the Art'', a [[Literature/TheCulture Culture]] Contact ship spends several months snooping about on Earth in 1977, before deciding not to contact us. Not so much because the Culture has any [[AlienNonInterferenceClause qualms about influencing]] the Earth -- it is just that the [[DeusEstMachina Minds]] have decided to use Earth as a control group. [[note]]In ''Inversions'' the Culture subtly guides a ''medieval'' civilization onto a more enlightened path.[[/note]] A passing reference in the appendix to ''Literature/ConsiderPhlebas'' does suggest that Earth has been Contacted by 2110 AD, at least. Humorously in ''Literature/{{Excession}}'', [[spoiler:when the Culture inadvertently becomes the victim of the trope, it is played completely straight.]]
* Used and subverted in ''Literature/TheNightsDawnTrilogy''. the hyper advanced aliens, the Kiint, refuse to solve humanity's "reality dysfunction" crisis, saying that each race faces it, and must find their own solution. On the plus side, they are more than willing to use their advanced technology to give humanitarian aid to those that become affected.
* Inverted in ''Literature/SpeakerForTheDead'', where it's the humans telling the piggies that they are not ready for all the fancy human technology like spaceships and ansible communication -- mostly just because the humans are afraid that the piggies will pose a threat to their superiority in space. This is a disputed policy and is one of the central conflict points of the novel.
** Quite a large part of the motivation for this is that humanity ''really'' [[Literature/EndersGame screwed up interacting with the last alien race they came across]], and don't want to do anything that may cause this lot harm.
** Not to mention that their entire race is a carrier of (and biologically dependent on for reproduction) a super-virus that kills humans in horrible ways. There are some very legitimate reasons to not want to let them get off-planet!
* In Creator/VernorVinge's novel ''Literature/ADeepnessInTheSky'', it's the humans hiding from the aliens while they wait for them to become Ready, and ''they'' are the ones who require technical assistance from the more primitive aliens.
* In [[Literature/TheBelgariad The Mallorean]], Belgarath tells Garion he needs 2,000 years of study before touching weather again. [[DisasterDominoes considering what Garion triggered,]] Belgarath is entirely right to demand this.

[[folder:Live Action TV]]
* In ''Series/{{Farscape}}'', John is given information about wormholes. The catch? It's behind a mental lock, and the SufficientlyAdvancedAliens who gave it to him state that if he isn't capable of unlocking the information on his own, he's not smart enough to use it wisely.
* ''Series/BabylonFive'':
** In the first-season episode "Deathwalker". A notorious war criminal has created a serum that gives the user immortality. Despite the heinousness of her crimes, Earth's government pardons her in return for turning over the formula. As she leaves the station, she reveals to the characters that had reacted to her in disgust the evil twist involved: every dose of the formula required [[PoweredByAForsakenChild killing another person of the same species]]. She intended to give the formula to everyone, and watch as they all fell into self-destructive chaos as a result to prove her twisted reasoning right. However, as she's leaving, a Vorlon ship appears through the jump gate and destroys the ship with her on it. When questioned about it, Ambassador Kosh says simply, "You are not ready for immortality."
*** In the tabletop game ''Babylon 5 Wars'' it turns out Deathwalker managed to jump on an escape pod, that was the object of a free-for-all among ships from the Younger Races. Ultimately a Brakiri ship managed to grab the pod and escape... Only to disappear in hyperspace, with all ambassadors getting the message "You ''really'' aren't ready for immortality".
** Sebastian, the Inquisitor sent by Vorlons to test Delenn's resilience and spirit, replies with this to Sheridan's questions about Vorlons.
** After Vorlons [[spoiler: leave the galaxy]] Lyta, who had been tightly involved with them, said that it would take humans more than a million years to get ready for a visit to the Vorlon homeworld.
* Basically the reason the Vulcans gave for not giving humans the technology to go to Warp 5 pre-''Series/StarTrekEnterprise''. The NX-01 is the humans' Warp 5 prototype, nearly 50 years and much enmity between humans and Vulcans later.
** Many instances in ''Star Trek'' media where the Prime Directive is invoked revolve around this trope; Starfleet crews are on occasion conflicted between moral pressure to help those in need and complying with the Federation's rules about "interfering" with less-advanced cultures.
** Humanity gets the shaft of this yet again when encountering an unknown life form on Velara III, which not only defies human understanding of what can constitute life, but is significantly more intelligent and advanced; they tell humanity to go away and come back in a few hundred years if they want to talk.
* The Tollan from ''Series/StargateSG1'' refused to share their technology with Earth because of a previous experience with a less advanced race that destroyed itself and the original Tollan homeworld. Flipped around a few seasons later, when this became the refrain of SG-1 when dealing with a less advanced society.
** The Asgard have this attitude toward Earth, but notably they subvert the trope and help humanity ''get'' ready, slowly introducing their technology with careful tutelage so humans can learn to use it wisely. In the final episode, they [[spoiler:pass on the sum total of their collected knowledge before committing collective suicide]].
* Used word for word in ''Series/{{Smallville}}'' by [[spoiler:Lex Luthor in Season 8]]
* In the first episode of ''Series/MahouSentaiMagiranger'', youngest sibling Kai is denied the chance to become a Magiranger by his mother because he's too reckless. After being scared witless by [[BlackKnight Wolzard]] and working up the courage to stand up to him to defend his older siblings anyway, he is then deemed worthy, becoming [=MagiRed=].
* Played with a bit in ''Series/HouseOfAnubis'' in season 1, as it is not the characters themselves who were not ready to build the cup, the cup could only be built and used during a certain time on a certain date, and by a [[TheChosenOne a certain person.]]
* Duncan's mentor tells him this in ''{{Series/Highlander}}'' in the flashback in 'Finale'. Duncan wants to fight Xavier St.Cloud, but Hamza tells him to flee into the desert because he isn't experienced enough to fight Xavier yet.
* An episode of ''Series/TimeTrax'' reveals the existence of a race of HumanAliens called Procardians. In Darien's native 22nd century, they have contacted Earth, and their diplomatic ship is on the way. Darien discovers that Procardians visited Earth in the late 20th century and found humans wanting (i.e. too primitive and violent). They decided to wait before coming back, only a female Procardian was accidentally left behind, prompting her mate to steal a ship and come looking for her (except he has no idea what she looks like to to the fact that their species ages in stages instead of gradually). Darien helps him find her and sends them to his own time to await the arrival of their ship.

[[folder:Professional Wrestling]]
* After Wrestling/{{Carl|itoColon}}y Colon loses the WWC Universal Title to Wrestling/AbdullahTheButcher, he says Eddie Colon, who was Puerto Rican Champion at the time and wanted to have a champion vs champion match with Abdullah, was not ready. Eddie beat Abdullah anyway, leading to chants approximate of "Take that Carly!" from the crowd in attendance.
* After winning a four way dance featuring three other {{tag team}}s by himself at ''Survival Of The Fittest'', Wrestling/CMPunk demanded that Wrestling/RingOfHonor give him stiffer competition, at which point [[Wrestling/JayLethal Hydro]], one half of one of the tag teams Punk had just beaten who himself might have won the match if Punk hadn't broken up his pin fall attempt, challenged Punk to take him on in a one on one match. Unfortunately for Hydro, Punk not only gave him this response but went on to prove it. Fortunately for Hydro, Punk's rival Wrestling/SamoaJoe decided to give him the guidance he would need to be ready in the future.
* This was Wrestling/PaulHeyman's response to an invitation to work for Wrestling/{{TNA}}. He was right, because as long money mark Dixie Carter was running things, the promotion was gonna continue bringing in the wrong people -- and at the rate things are going, it's highly doubtful TNA will ''ever'' be ready, let alone if it gets the ''chance'' to be ready at all.
* What Tasha Simone had to say in regards to Wrestling/MsChif, when she read [=MsChif=] was coming to the PGWA to avenge a student of hers that Simone had beat down, Rebecca Raze.
* After Wrestling/KazuchikaOkada had taken the pro wrestling world by surprise and Wrestling/{{New Japan|ProWrestling}} by storm upon his return from his North American "excursion", Wrestling/BulletClub recruited Wrestling/AJStyles in 2014, who insisted that contrary to popular belief Okada was still the lost kid he met in the states, to deal with him. Styles and Bullet would have the advantage over Okada and Chaos for a year and even when Okada did decisively defeat and put Styles in his rear view mirror he was [[BreakTheHaughty noticeably humbled by the experience.]]
* After losing the World Of Stardom title, Kairi Hojo offered a handshake to new champion Meiko Satomura, who slapped her hand away, saying Hojo would have to wait.
* Wrestling/JayLethal at first showed no respect towards Wrestling/RingOfHonor's newest contracted wrestler, Wrestling/LioRush, but after Rush's first match under contract, which ended up being against Lethal due to Wrestling/TomohiroIshii taking the Television Title to Wrestling/{{New Japan|ProWrestling}}, Lethal said that Rush may one day become a better wrestler than him. Till then, Lethal maintained he was the best wrestler in the world and that ROH putting that year's top prospect against him proved they were out of ideas([[Wrestling/ColtCabana ROH wasn't yet]]).
* It was implied Shayna Baszler had tried to tell Nicole Savoy this when the latter announced her intentions to enter a 2016 catch as catch can tournament. Savoy would admit she wasn't quite ready after being eliminated by Baszler.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' sees this as a very common sentiment from the Eldar to humanity. Humanity's usual response is a bolt shell to the face.
** As an additional perk, many of the pieces of Eldar tech would be ''rejected'', because the Imperium includes a ''very'' strong belief in [[NewTechnologyIsEvil Any Technology We Don't Have Is Evil, Unless It Comes Out Of An STC]].

[[folder:Video Games]]
* The title phrase was actually used as a slogan in ads for the original UsefulNotes/PlayStation - though in printed ads, it was written in the more cryptic form "U R NOT [[color:red: E]]", with the E being in red.
* Slight variation: In the opening cinematic for the ''VideoGame/WorldOfWarcraft'' expansion The Burning Crusade the main villain (sort of) Illidan can be heard saying "You are not prepared!" at the beginning and end of the cinematic and during his pre-battle monologue (and if you are indeed not prepared, he will say it again and again...) Enough that eventually it became his [[MemeticMutation memetic]] CatchPhrase.
** [[https://www.youtube.com/watch?v=mUfOIvlC6Eo NOW.]] [[PunctuatedForEmphasis YOU. ARE. PREPARED!]]
* ''VideoGame/KingdomHearts'': Creepy guy in brown cloak: "One who knows nothing, can understand nothing..." (referring to Sora)
** Subverted, as creepy guy is later shown to be greatly mistaken about his beliefs and knowledge. The sequel features another arrogant old man with a thing for vague statements about your ignorance, he turns out to be wrong about many things too. The Kingdom Hearts world isn't a good place to be an enigmatic mentor.
** The latter example, though, actually turns things around. In the end, he admits his own ignorance and uses the knowledge he gained from the experience to make the Big Bad's defeat possible.
* After the timeline in ''VideoGame/TheJourneymanProject'' has been altered, the entirety of FirstContact with the Cyrollans is revealed to have consisted of these four words before their ship departs.
* ''VideoGame/MassEffect1'': Humanity is not ready for a human Spectre, or a seat on the Citadel Council. [[spoiler: By the end of the game, they have both.]]
** When the Council tried to uplift the krogan before they were ready, they subsequently went on a galactic conquest, so they have their reasons. In the second game, Mordin argues that this trope is what ''should'' have happened with the krogan, allowing them to evolve culturally and technologically on their own instead of being shaped into a weapon and pointed at the [[BugWar rachni]]. "Like giving nuclear weapons to caveman."
* Rather early on in ''VideoGame/PhantasyStarIV'', Rune tells Chaz that at this "[[LeaningOnTheFourthWall stage of the game]]" he's not ready to take on the BigBad. Chaz, who was as yet unaware that he's being swept up into things bigger than he can grasp, is nonplussed by the statement.
* Word for word one of Kung Lao's lines in VideoGame/MortalKombatX, in a match up against Kung Jin.
--->'''Kung Lao''': You provoke me?
--->'''Kung Jin''': Just want to test myself against you.
--->'''Kung Lao''': You are not ready.
* Said several times to the protagonist by the [[OurAngelsAreDifferent Solar]] in ''VideoGame/ThroneOfBhaal'', in reference to their powers as the spawn of a dead god. Her entire purpose is to fix this little problem, mostly by giving lots and lots of {{Exposition}}.
* * In the ''VideoGame/{{Fallout}}'' series the Brotherhood of Steel was started with the idea of preserving pre-War tech as a means of salvation for humanity despite the Brotherhood's secrecy and aloofness. Overtime this was turned into a ideology that prevents outsiders from joining the Brotherhood and finding, let alone ''using'', any pre-War tech left uncovered. This is most seen in the East Coast Brotherhood chapter as the Outcasts split from the main group when Elder Owen Lyons wanted to aid the Capital Wasteland and only returned when Elder Arthur Maxson, the decedent of founder and High Elder Roger Maxson, made changes and broker a peace agreement allowing the Brotherhood to fight at full strength again as well as improve on old tech. Maxson still believes that tech should still be hoarded to prevent abuses but is OK about some low tech being used.

[[folder:Web Original]]
* Blog/MarkDoesStuff: Mark Oshiro, completely spoiler-free, is not prepared as his fans constantly remind him. He wasn't prepared for the ''Twilight'' books, but there it took on a more somber tone. And he certainly hasn't been prepared for any of the other stuff he's been reviewing.

[[folder: Western Animation ]]

* The ''Franchise/StarWars'' example between Luke and Yoda was parodied in ''WesternAnimation/FamilyGuyPresentsLaughItUpFuzzball.''
--> '''Yoda/Carl''': Y-You're not done with all your Force stuff, a-and besides, you can't fight Vader. Only an experienced Jedi could fight Vader.
--> '''Luke/Chris''': Well, why don't you go?
--> '''Yoda/Carl''': Yeah, you're probably ready to fight Vader.
* In Episode XXXII of ''WesternAnimation/SamuraiJack'', after Jack fails to defeat The Guardian and gain access to the time portal, we see in a FlashForward that Jack will eventually use the portal when he's ready. [[spoiler:[[BigBad Aku]] decided [[ScrewDestiny he didn't like that idea]], blew up the portal and (presumably) killed the Guardian too over the 50-year {{Timeskip}}]].
-->'''The Guardian:''' You can't use it yet, Samurai Jack. Not yet. Not yet.
* In ''WesternAnimation/Ben10UltimateAlien'', Azmuth considers Ben to be this regarding the new Omnitrix he is building (He changes his mind by the end of the series, though).
* In ''WesternAnimation/AvatarTheLastAirbender'', OldMaster Jeong Jeong says this to Aang about his wanting to learn firebending. Traditionally, the Avatar learns the elements in the order of the Avatar cycle (Air-Water-Earth-Fire), so Aang wouldn't be ready to learn firebending until he mastered water and earth. Though Jeong Jeong relents, it's proven that Aang ''wasn't'' ready, as his impetiousness results in Katara getting burned.
* In the SequelSeries ''WesternAnimation/TheLegendOfKorra'', the Order of the White Lotus thinks of this for Korra, believing she wasn't ready to learn Airbending because of her lack of spirituality. But thanks to Katara approving of Korra learning it, they instantly agree with her.\\
Experience prove both Katara and the White Lotus have a point. Korra ''wasn't'' ready to learn airbending yet. But by leaving her sheltered home and going to Republic City she matures enough to learn it.


[[folder: Real Life]]

* This is the justification behind teenage driver regulations. Even though the typical teenager might have had driver's education, s/he is still too inexperienced to be given the responsibility to drive unsupervised especially at night. Unrestricted privileges are usually granted only by the time the driver turns 18-21 (depending on the country) and is generally considered more mature.
* This is also the reason most societies have age of consent laws. Even though humans are capable of sexual reproduction from the instant they hit puberty, most societies judge pubescent early to mid teens as not having the emotional maturity and intelligence to handle the responsibility of sexual relationships and the burden of childcare.
* The nuclear Nonproliferation Treaty was put in place with this exact justification - that nations which didn't already have nuclear weapons for decades at this point in time, won't have the cultural maturity and restraint to be able to use them wisely. Owing to the fact that the nations allowed to be exempt from this treaty were primarily European or European derived nations [[AndZoidberg and China]], [[RuleOfCautiousEditingJudgement this treaty is open to controversy.]]
