!!TV series
* The kidnapper in "The National Anthem" -- an anonymous individual who with one action sows the seeds of chaos within an entire community and forces them to dance along to his tune through provocative, vulgar and inflammatory actions, derailing all discussion until it's about him and what he's done and making everyone else do [[spoiler: all pretty much just to prove a point about how stupid everyone else is for getting caught up in what he's done]]. So, basically a glorified {{Troll}}, in other words.
* Also regarding the kidnapper in "The National Anthem": it's possible that [[spoiler:he committed suicide because the public appeared more concerned with pressuring the Prime Minister into acceding to his demands rather than worrying about the Princess's safety. If he wasn't a sociopath, realizing how horrible people can be would make a plausible DespairEventHorizon]].
* Either FridgeBrilliance or FridgeHorror depending on your viewpoint, but in ''15 Million Merits'' the omnipresent exercise bikes that ''apparently'' provide power to society don't appear to be connected to anything. This would make the constant peddling totally pointless. Given the other omnipresent aspect of this society, constant entertainment on screens everywhere, the bikes could be just another way to occupy a populace that actually has nothing to do.
** It's shown that you obtain the "merits" through the cycling, but exactly what the cycling is meant to achieve is never clarified, although as a bit of FridgeBrilliance this is the point - the bikes are useless busy work which everyone has to do to get by, even if it's totally pointless, as a metaphor for the work everyone has to do to get by in the real world today. Ever feel like your job is totally useless and produces nothing worthwhile? That's what the bikes are meant to be.
** Isn't it suggested that cycling provides electricity to power all the screens? So people are kept compliant by watching trash to distract them from their meaningless jobs... which exist only to produce the trash that keeps everyone compliant... Consumer capitalism in a nutshell.
*** Yes that's what the populace is lead to believe but the humans generally only provide ~250 Watts while cycling, ~400-500 Watts if they really push themselves. Now currently a 52" TV will use about ~285 watts (varies depending on manufacturer of course) even taking into account future improvements in energy saving technology it's very unlikely humans alone would be able to power the power city that includes lifts, vending machines, lights, touch-screen mirrors and of course the omnipresent floor to ceiling [=TVs=] complete with motion detectors. It's possible that they are simply there to augment the power consumption but personally I think it's just to keep the population busy and to make them think they're doing something worthwhile.
**** [[MST3KMantra It's a metaphor, nothing more.]] It doesn't make objective sense but then it's not meant to.
** According to Brooker, they at most run the screens and it's more about preserving social structure and keeping people busy than actually producing any power.
** It doesn't need to be connected to anything, if the wheels are constructed in a certain fashion with magnetic material and the base has an electric circuit, then it could be an induction generator, and any other work consequence of the activity can just be connected to the base, hidden wires and all(or, why not, wirelessly; it's the future!) Going into the nitty-gritty of how much power a human being can actually generate as such will probably not wield very impressive values, though, so we enter "Matrix's giant human battery" territory: the message is more important than the factual nature of the mechanism.
* Either FridgeBrilliance or FridgeHorror depending on your viewpoint, but at the end of ''15 Million Merits'', the main character Bing is seen [[spoiler: looking out of what might be a huge Fake vista of woodland]] or is alternatively [[spoiler: looking out of a real floor to ceiling set of windows showing lush green forest as far as the eye can see]]. This means that he has either [[spoiler: swapped his tiny cell for a larger Gilded Cage]] or [[spoiler: The endless drudgery of cycling that the majority of the populace does, has enabled most of the planet to resort back to natural forest]]. Either ending can be seen as ultra depressing, but YMMV.
* In ''15 Million Merits'', the citizens all sleep in their own single cells and are bombarded with pornography every few minutes. One method of population control, I suppose...
* In ''15 Million Merits'', people who are fat are discriminated, as they do no exercise and do not power up the screens that everyone uses. Because of this, they are given either menial jobs such as cleaning, or are made to appear on TV where they are abused for the entertainment of those watching. Oh, and you can shoot them in computer games. So to sum up, the people who are considered to be a waste to society are abused on TV as entertainment and given menial jobs where they suffer everyday. Sound familiar?
* FridgeBrilliance in 15 Million Merits: it's implied, when Abi goes for her Hot Shot audition, that the Cuppliance is responsible for her [[spoiler:going into pornography]] more than anything else. But then, Bing goes on as well, [[spoiler:''avoids drinking it...'' and then goes along with the panel's offer and gets swallowed up by the machine anyway]]. Maybe the drink didn't really do that much, they just ''thought'' it did?
** I always believed that she went through with it because Bing had spent so many merits on her for the audition, that she thought that he would've wanted her to accept it.
** This troper thinks of it more like FridgeHorror: [[spoiler:As Bing dishes out his heartfelt rant at the judges and the audience, it makes the viewer believe that he's genuinely outraged by all of it. But seeing him later, doing the same thing for fame and celebrity, not only clarifies that he didn't really mean what he had been saying, but everything he has done since has been ''of his own free will''! He's clearly that amoral.]]
*** He did mean what he was saying: It was largely unplanned, and he countered one of the judges when he described it as an "act". The problem was that he had no plan beyond saying it, and the judges were "swayed", but not in the way he was expecting. They then decide to ''let him'' say all that stuff and even put it in a timeslot, while the crowd goads him into doing it. Regardless of whether it was true or not, or was a genuine tirade against the entertainment industry, a simple rant isn't going to change the system, but it's more likely the system will [[TheManIsStickingItToTheMan assimilate the person doing it.]] [[spoiler:Bing clearly feels as unfulfilled in his new role as he was on the bikes.]] That's what the scenes were meant to illustrate.
* ''15 Million Merits''? Why not 12 million? 20 million? Because in the future, everybody will be famous for fifteen minutes.
* FridgeBrilliance for ''The Entire History Of You''. The memory grains that store everything you're doing at every point in your life are a clear metaphor for social networking, and the habit of recording everything one is up to as a status update. Do you really want to keep all that around forever? Rendered somewhat [[{{Defictionalization}} scarier]] by Facebook's introduction of a "timeline" feature, which quite literally lets you zip around to see your exact thoughts, location and activities at any point in your life where Facebook has data to display, from your birth onwards. Virtually everything depicted in the programme is now at least vaguely possible.
* In ''The Entire History of You'', Liam's suspicious and paranoid behaviour - when you think that spouses in regular circumstances who [[spoiler: believe their partner is cheating on them]] are usually 'right', then his behaviour is totally justified, and magnified, by being able to replay all the memories to pick up on all the things that triggered those thoughts over and over again over the years.
* In ''Be Right Back'' why didn't Martha just [[spoiler: call the company that made Ash and have him taken away, rather than telling him to literally jump off a cliff.]]
** Grief does strange things to the human mind.
** Given the theme of the story, which seems to be a send-up of "Literature/TheMonkeysPaw", it's likely it's non-refundable.
* Why is the Ash replicant hidden in the attic in ''Be Right Back''? Because that's where Ash said his mother would hide the belongings and anything that reminded her of the family members she lost until she was able to cope with their death. Martha simply took the last story Ash told her, and did it to the replicant when she couldn't get rid of it. And judging by the presence of her daughter, she's being holding her grief for Ash's death for ''years''.
* FridgeBrilliance time (and crosses into FridgeHorror as per this show's norm): in ''The White Bear'' the Observers are initially set up as brainwashed masses who do nothing but give the "hunters" an audience under the infulence of some malignant signal. [[spoiler: After the reveal it's made clear that the "observers" are just extras from the public put there to enhance the terrifying experience for the condemned as well as, which is outlined in the last few minutes, to "have fun." Meaning they are there willingly, doing pretty much what their characters are doing, the only difference is they have free will and are doing it ''for fun.'']] This makes the already blunt TakeThat of the Observers that little bit more sinister.
* Fridge Logic: In the UK (Where judging by the accents, we assume the ''White Bear'' episode is set), the government actually signed the United Nations Convention Against Torture bill, which would forbid them of practising torture of this calibre. If they broke this bill, the convention and its subsequent nations would intervene very, very swiftly, meaning the White Bear Justic Park wouldn't exist without serious argument with other countries...
** Similarly, as much as people hate murderers, and would never defend the kind of torture Victoria condoned, there would realistically be a large amount of people protesting against White Bear. Amnesty International and The UN universal Declaration of Human Rights would certainly cause trouble for the White Bear justice park. There's no way that a place like that could realistically exist without at least some Vocal (and powerful) Minorities getting in the way.
** In-universe, we can possibly argue that it's a TwentyMinutesIntoTheFuture-style scenario wherein there's been some kind of drastic political and social upheavals which have rendered the above legal obstacles moot, or an AlternateHistory where such legislation does not exist. Out-of-universe, it's an UpToEleven satire of the kind of NotSoDifferent mindset that tends to emerge whenever something horrible happens like a child-murderer is discovered and arrested, and there's usually a lot of 'hanging's-too-good-for-them' style rhetoric from pundits on the sidelines (both in the media and outside of it) and conversations which tend to quickly get consumed with all the kinds of nasty things that ''should'' happen to them instead of just going to jail. Brooker's constructing what is, acknowledged, a fairly exaggerated scenario to suggest that, ultimately, this kind of mindset is just as abhorrent as the kind of mindset that would find amusement in [[spoiler: torturing a little girl to death]], except it's masking a similar kind of sadistic desire to do unspeakable harm (whether physical or psychological) to another human being in a cloak of smug self-righteousness and the belief that 'justice' would be done. He's raising the question that if you were to sadistically torture a sadistic torturer, even if your motives were 'good' wouldn't you ultimately end up being just as bad as the torturer?
** Astonishingly, there's currently some fairly clouty tabloid-led opposition to human rights legislation in the UK, so getting out of those treaties in the near future is sadly one of the least implausible things in Black Mirror.
* From "White Bear": [[spoiler: The white bear was a symbol for Jemima's disappearance. It's also the name of the Justice Park where Victoria is imprisoned. Judging by these two facts, it's likely that Victoria and her fiancée's crime was the inspiration for the Park's existence in the first place]].
* At the end of "White Bear", Baxter says it will take about half an hour to erase Victoria's memory of the day. She apparently spends the entire half hour in excruciating pain. If around 12 hours have passed since she woke up (which seems a reasonable estimate), then the device takes roughly an hour to erase 24 hours' worth of memories. Based on that ratio, Victoria may have spent over a ''year'' in agony having her twentysomething (or more) years wiped ''before her sentence even began''.
* A pretty simple one, but I only realized it later. In the Christmas Special, Greta complains that her toast is overdone and sends it back, although she (or her cookie's internal monologue, or both -- it's not clear which) worries that the woman who brought her breakfast will hate her. She's exactly the sort of person who ''would'' want a "cookie" to micromanage her environment for her. (Also, she worries about clearing her inbox. Maybe the "cookie" takes care of that too?) And of course this is emphasized by Matt getting Cookie!Greta to try controlling the toaster and then eating the toast throughout their conversation. Also, considering the fact she worried that the woman who brought her breakfast will hate her, does she really understand how "cookies" work, and does she ever worry if her "cookie" hates her?
** Since Matt has to explain how cookies work ''to Greta's cookie'', and that [[spoiler:cookies are shown to preserve memories of their hosts]], it is implied that Greta doesn't know; moreover, given that he explains it ''to Potter'', it seems to be a quite closely guarded trade secret.
* The name "cookie" itself: it's after [[https://en.wikipedia.org/wiki/HTTP_cookie#Uses browser cookies]].
