Jeff: Ah, so you and your mom are both wacked?
Hayley: I dunno. That's that whole nature versus nurture question, isn't it? Was I born a cute, vindictive, little bitch or... did society make me that way? I go back and forth on that...Everyone knows about some of the fundamental questions to life - who are you, what do you want, where did you come from, and where will you go? Those are the "what" questions, but this is the "why". Why did you say that? Why did you do this? Why were you there? Innate qualities and personal experiences both play an important part in determining or causing individual differences in physical and behavioral traits, but this raises the question - which was more 'responsible' for such traits? Were these Abusive Parents abused themselves, and take that out on their own kids, or were they always malicious to begin with? Is the concept of free will (i.e. truly independent thought and truly independent decision-making) valid, or are your decisions brain-made "echoes"? Are your personalities determined more by genes, are they influenced your own experiences, or are they made so that your personality truly is unique? Currently, scientists tend to think they both have about equal influences. At any rate, fiction can have a field day with this, and depending on the writer, it can skew to either side of the argument.
Tropes that tend to skew towards "Nature":
- Born Lucky
- Born Unlucky
- Born Winner
- Generation Xerox
- Genetic Memory
- Heroic Lineage
- In the Blood
- Lamarck Was Right
Tropes that tend to skew towards "Nurture":
- Blank Slate
- Conditioned to Accept Horror
- Freudian Excuse
- More Than Mind Control
- Nurture over Nature (obviously)
- Raised by Natives
- Rousseau Was Right
- Stockholm Syndrome
- Then Let Me Be Evil
- Upbringing Makes the Hero
Examples:Anime and Manga
- In Elfen Lied, a point is made about whether or not the diclonii really are malicious, or if their cruelty is a byproduct of how they were raised. Lucy appears to be the latter; Mariko appears to be the former. Note that neither side is plausible in the manga. The manga implies that all diclonii are some degree of aggressive toward humans no matter how they're raised.
- Naruto has Sasuke, Gaara and Naruto; their personalities and mindsets were influenced by their upbringing, but whereas the former two dealt with it badly, the latter was able to pull through because he was luckier than the others, though he convinced Gaara to change his view on life, and he's trying to do the same to Sasuke.
- There's a lot of In the Blood going around, in that Sasuke's family has a long habit of choosing 'power' over 'strength' that supposedly goes back to the ancient founder of their clan, the elder son of the Sage of the Six Paths. Doujutsu and sociopathy apparently have a causal link, though not an inescapable one.
- On the other hand, Gaara apparently had a very loving mother and a cold bastard of a father, and to complicate matters was raised by an uncle who was very kind and looked just like his mother. And was also ANBU and accepted the mission of making a hit on the six-year-old boy he'd raised, in order to test his emotional resilience. The zombie of Gaara's father acknowledges this as a flawed methodology.
- And despite never knowing them, Naruto is just like both his parents.
- The Akumetsu are several dozen clones made from an extremely evil guy as part of a project to assure his immortality, all separated as infants and raised in may households across Japan, all under the first name Shou and all but one unaware of the others. They are nothing like their original DNA donor, apart from a possibly-related mad indifference to normality. They are, however, so much like one another they very nearly have a Hive Mind within a weeks or even days of banding together.
- I.e., both sides of this trope are being used and abused with reckless abandon.
- Note that they did start swapping important memories around pretty early, though not many. To a certain extent they all imprinted on the Shou who inspired the whole Akumetsu project, but even before that they were so alike it's creepy, and honestly that Shou is less like the others than any of them.
- Fullmetal Alchemist is vague on whether homunculi are naturally malicious or if they're simply not raised well.
- This is one of the fundamental themes of One Piece, primarily in the case of the protagonist Luffy and his brother Ace. The question of whether or not the blood in your veins determines who you are — somewhat played with in that Luffy and Ace did end up as criminals like their parents, but in their case it was their only hope of survival, seeing as the World Government is firmly on the "nature" side, deeming them to be evil just because of their parents' crimes and would've killed them immediately had they been aware of their existences earlier. Also played with in that despite taking after his father, Ace more or less disavowed him and considered Whitebeard his real father. Luffy himself was not influenced by his parents seeing as he never knew he had them. The issue is even further muddled by the fact that the World Government is blatantly evil, making Luffy and Ace downright heroic in comparison.
- This is arguable in the case of Donquixote Doflamingo once we see more of his past. Was he born evil like Rosinante suggested and incapable of veering off of his dark path? Or was it a combination of the mistakes of their father, Homing, whose actions caused the death of their mother, mixed with the influence of the executives, who provided him with his Devil Fruit and his signature flintlock? The latter created a conflicting message between Homing wanting Doflamingo to be humble and the executives who would burn down a city if Doflamingo tripped on its sidewalk, suggesting that while Doflamingo always had some darkness in him, it was the executives (particularly an 18-year old Trebol) who egged him on and pushed him over the edge.
- It is all but stated in Dragon Ball that Saiyans are naturally ruthless Blood Knights who care about little except for fighting. When Goku hit his head and forgot his Saiyan memories, he was raised to be the good person we know by the kind senior Gohan. However, with supplemental material we have seen that they were good Saiyans and Goku's mother was one of them, bring into question if Goku's goodness is genetic as well as nurture.
- Brought up in most depictions of Superman: Superman is Kryptonian, but was raised by kindly old adoptive parents. In older stories, it was usually implied that his superior Kryptonian heritage and abilities were the cause of his strict moral compass, but in latter stories (especially after other, villainous Kryptonians, were introduced), it's outright stated that Superman's upbringing is responsible for creating who he is.
- During his Darker and Edgier interpretation, Superboy was all about this trope. Superboy is a clone created by human DNA that was altered and/or combined with Superman's DNA (Depending on the Writer). In the earliest years, his "daddy" was Paul Westfield and later, it was retconned to be Lex Luthor instead. Neither of them are very nice people. So, Superboy constantly questioned whether he was destined to become good or evil based on the genes provided by Superman or his human father.
- In his New 52 incarnation, Superboy starts flat out amoral. The group that cloned him outright questions whether his lack of human empathy is due to being a clone, being half alien, or lacking Superman's overall upbringing. He slowly starts to learn empathy and compassion.
- The entire plot of Justice League 3000 (which sees the JLA "resurrected" in the 31st century) hinges on this. Superman lacks the guiding hand of the Kents and is thus a Jerk Jock with a massive ego, Batman never suffered the loss of his parents and doesn't even wanna be Batman, Wonder Woman is a violent Blood Knight constantly looking for someone to kill, and so on.
- In Do Not Meddle In The Affairs Of Wizards, Harry's lawyer argues that the reason Dumbledore forced Harry to stay with the Dursleys was because he wanted to prove that it was nature, and not nurture, that drove an individual, and thus prove to himself that Tom Riddle would have gone bad, no matter what he did.
- One of the major differences that makes the Aftermath Of The Games universe an AU to the MLP:FIM Canon is that Twilight ends up in charge of raising a filly version of Starlight Glimmer because unlike her canon counterpart, Starlight refused to surrender and atone for her actions during "The Cutie Re-Mark", so Twilight was left with no choice but to wipe her out of existence by convincing the nine-year-old Starlight to run away from her Orphanage of Fear and become her apprentice. Twilight and everybody in the know about the filly's origins agrees that part of the reason why the original Starlight became a major psychopath was because spending her entire foal hood in an abusive orphanage prevented her from learning how to connect properly with other ponies, so they take extra care to raise her in a loving enviroment and build her a large support network of ponies that she's able to trust so she gets on the right path. However, because mental illnesses are a mix of both genetics and upbringing, Starlight demonstrates early warning signs of her older self's equalistic and fanatical behavior during Integration, and Twilight fears the possibility that nothing she can do will make a difference.
- A subject in Godzilla Junior's character arc in The Bridge. Junior is the third "Godzilla" behaves very different from his predecessors, being a heroic soul who's saved millions of human lives by acting as their protector from malign kaiju. However there is a fear the things that are similar between him and his father and grandfather, such as a sense of revenge and a temper, which could cause him to Turn Out Like His Father. Junior himself is aware of this and is scared by the prospect he might be destined to go down that path. Ultimately though, nurture wins because of Junior's close tie to his mother, Dr. Azusa Gojo; who points out that some similarities doesn't put him on a predetermined path and he has plenty of differences that make him who he is. It's clear when Junior learns to forgive a former enemy rather than seek revenge, he takes more after Azusa than Godzilla Senior.
- The entire plot of Trading Places begins when the Duke brothers place a bet on which is true.
- Long before Trading Places, two businessmen tested this on The Three Stooges in "Hoi Polloi".
- In Man of Steel, Zod is a destructive Knight Templar but he was bred and raised to be a soldier through bloodline and genetic manipulation and the workings of Kryptonian society. Clark is descended from Kryptonian scientists, but he had a natural conception and birth and was raised by Kansas farmers. Though the film hints at Clark being geeky as a child, he chooses a different career in life which would have been impossible on Krypton.
- This exchange from Hard Candy:
Jeff Kohlver: Ah, so you and your mom are both wacked?
Hayley Stark: I dunno. There's that whole nature versus nurture question, isn't it? Was I born a cute, vindictive, little bitch or... did society make me that way? I go back and forth on that...
- Isaac Asimov used this with regards to robots, of all beings, in the short story compilation/narrative I, Robot, by comparing physically and positronically identical robots who developed with different frames of reference (generally resulting in aberrant behavior).
- We Need to Talk About Kevin is based around the nature/nurture debate — did Kevin grow into a murderer because mummy didn't love him enough, or was he a psychopath from the word "go"? Basically, it weighs up blaming the mother when her child grows into someone diabolical, against the disturbing idea of being born evil.
- Worldwar features aliens raising humans, and humans raising aliens, in order to see how close they can make each species to their own.
- Roose Bolton in talking with Theon during A Dance with Dragons openly wonders this about the relationship between his bastard son Ramsay and the first Reek, as Roose doesn't know if Ramsay's depravities were present before he sent Reek to serve him.
Roose: Did Reek make Ramsay, or did Ramsay make Reek?
- A recurring theme in Jack London's White Fang is whether the clay one is shaped from or the way in which they are shaped is a more significant part of what makes a man or dog.
- The Mysterious Benedict Society books practically compel the reader to consider the question, with the case of Nicholas Benedict and Ledroptha Curtain, who are identical twins, but turned out very differently. How much of Mr. Curtain's wicked behavior is simply his nature, and how much can be put down to the circumstances of his life? And The Extraordinary Education of Nicholas Benedict shows how very different things might have turned out for Benedict had he not found the help of some kind-hearted adults in his youth.
- Frequently debated in Law & Order, to the point where Dr. Olivet said in one episode that she didn't want to rehash the "nature versus nurture wars", saying that both sides were equally right and wrong.
- On CSI, when Catherine Willows argued that people were shaped by their experiences as much as by their genetics, Gil Grissom agreed, saying, "Your DNA is what you are, not who you are."
- The entire point of the experiment with the clones in Orphan Black seems to be to explore this. The clones were placed into different environments and were observed by "monitors" who reported their every move.
- Discussed in Smallville episode "Scion". Clark is worried that Conner (who is a hybrid clone of him and Lex), will embrace the dark side, and he seems to do under the influence of red kryptonite courtesy of Lionel. Once he's free from it, he chooses to side with Clark. At the end of the episode, Clark tells Conner that everyone has a shadow inside, but it doesn't mean you have to embrace it. Lois then comments "Seems to me that Clark Kent's nature and nurture won out in the end."
- Basically the main conflict (besides the iconic "science versus technology") between the colours Green and Blue in Magic: The Gathering. Green, naturally, favors Nature, believing in genetic fatalism and predestination. Blue's entire philosophy relies on the concept of tabula rasa, and therefore it sides with nurture.
- Mass Effect: Exactly how much asari with a non-asari parent get from genetics, and how much from upbringing, gets a lot of flip-flopping. The asari claim that mating with non-asari just scrambles the daughter's genes a bit, but the daughter frequently develops traits of the non-asari parent. Matriarch Aethyta had a krogan father and is kind of a Grumpy Old Lady. Another minor asari in the second game had a batarian* father and acts rather amoral and mercenary. Then there's Mordin's off-hand remark in his patter song that asari-vorcha offspring have dairy allergies.
- Metal Gear: A recurring theme in the series, Specifically in Metal Gear Solid 2: Sons of Liberty, Raiden is contrasted with Solid Snake and his clone brothers. Whereas the Snakes are genetically altered clones of Big Boss, Raiden is a child soldier who was raised by Solidus (one of the Snakes) and then subjected into the S3 Plan, a simulation program meant to train a soldier in Solid Snake's image.
- In Sinfest, Slick blames his upbringing, and then concludes that doesn't change his character.
- A slightly more literal example than usual shows up in this strip of El Goonish Shive, where Susan receives advice from a Good Angel, Bad Angel pair representing her Nature and Nurture. The darker, and more distant Nurture so strongly objects to the bubbly Nature's suggestion that Susan hug Tedd, that she gags Nature to make her shut up. This was one of the clearest illustrations of how much Susan's difficult past affected her.
- This was the title of the season one finale of The Spectacular Spider-Man. It concerns the different upbringings between Peter Parker and Eddie Brock.
Brock: Our parents may have died together, but you had your precious aunt and uncle. We had no one, we've always been alone... until now.
- Crops up in the episode "Dragon Quest" of My Little Pony: Friendship Is Magic, where Spike tries to learn more about being a dragon, but he learns that by nature, dragons are destructive and greedy. He then learns to embrace being raised by ponies as he has not become like them.
- Inevitably brought up in stories involving:
