Life sucks sometimes, doesn't it? You got fired from your job, your girlfriend broke up with you, and you're about to be evicted. Things have really taken a downward turn. But don't worry! It certainly isn't your fault.
See, there's these people. Bad people. They don't like you. They don't like much of anyone. And they oppress you. They have satellites that can beam pictures into your head, that's why you kept seeing all that stuff, lost concentration at work. They plant radios in your teeth so that you think you're Hearing Voices. They shoot these weird rays into your brain so that you have those... urges... it's not you. It's them. It's all their fault. They're the ones doing this to you! It's all them. All them, all them, all them, all-
What, you don't believe me? Well, you have to. Because otherwise, it would be you. It'd be all your fault. And that can't be right.
- Attack on Titan: The memories of the entire population seem to have been altered when humanity entered the Walls, removing all knowledge of the world outside the Walls. When Erwin let slip his father's theories in public, the 1st Squad murdered him.
- Welcome to the N.H.K.: Sato and his senpai blame all of the troubles in their lives on conspiracy theories. Sato even believes the titular NHK is actually an organization which exists only to turn civilians into hikikomori like himself.
- Equestria: A History Revealed: The Lemony Narrator seems to think that a lot of Equestria falls under this, and sees Celestia as the Diabolical Mastermind, even when things clearly point against that. That doesn't stop her from believing it though, and creating her own theories through copious amounts of Insane Troll Logic.
- In a more literal example, she states that as a failsafe, Celestia had placed a subconscious mind control spell on all of the mane six to control them if they get out of hand. And that's just one of the many mind control examples she believes Celestia supposedly utilizes.
- One Flew Over the Cuckoo's Nest: Chief Bromden's belief in the Combine.
First I had a quick thought to try to stop him, talk him into taking what hed already won and let her have the last round, but another, bigger thought wiped the first thought away completely. I suddenly realized with a crystal certainty that neither I nor any of the half-score of us could stop him. That Hardings arguing or my grabbing him from behind, or old Colonel Mattersons teaching or Scanlons griping, or all of us together couldnt rise up and stop him.We couldnt stop him because we were the ones making him do it.It wasnt the nurse that was forcing him, it was our need that was making him push himself slowly up from sitting, his big hands driving down on the leather chair arms, pushing him up, rising and standing like one of those moving-picture zombies, obeying orders beamed at him from forty masters. It was us that had been making him go on for weeks, keeping him standing long after his feet and legs had given out, weeks of making him wink and grin and laugh and go on with his act long after his humor had been parched dry between two electrodes.We made him stand and hitch up his black shorts like they were horsehide chaps, and push back his cap with one finger like it was a ten-gallon Stetson, slow, mechanical gestures - and when he walked across the floor you could hear the iron in his bare heels ring sparks out of the tile.
- Then, at the end of the book, just before McMurphy tries to strangle Nurse Ratched, Chief Bromden has a terrifyng moment of clarity and realizes the true Mind-Control Conspiracy:
- In Iain Banks's novel Walking on Glass, Steven Grout believes that he is being influenced by orbital mind control lasers.
- VALIS's Horselover Fat is a victim of the three-eyed Soviet space aliens' orbital mind control lasers. Said lasers are pink.
- In The Manchurian Candidate, Communist brainwashers turn a soldier into an assassin through some sort of mind-controlling hypnosis.
- Richard Matheson's story "Legion of Plotters" takes this to its logical— and tragic— conclusion.
- Night Chills by Dean Koontz has a small town being used as a testbed for such a conspiracy, the control agent spread by a combination of Water Source Tampering and Subliminal Seduction.
- The X-Files:
- In the Lone Gunmen origin-story episode Suzanne Modeski found a tracking device the Conspiracy had put in her tooth. Which she removed with pliers, somehow managing to avoid passing out from the pain.
- Mulder's water was spiked with LSD in "Anasazi" in order to elicit violent behavior.
- In "Wetwired", the television was sending subliminal messages through red/green wavelengths, again eliciting violent, homicidal behavior. Scully almost succumbs, nearly shooting Mulder in the process. Mulder is unaffected, as it is revealed he is red/green colorblind.
- The appliances in "Blood" were commanding normal citizens to kill by catching them when their intense phobias were exploited. As in "Anasazi", an LSD derivative was used to incite the behavior.
- Starsky & Hutch: in one of the episodes, a serial killer turns out to be a seriously deranged man who believes he's being mind-controlled. He wears tinfoil under his clothes to shield himself from radio waves and his house has tinfoil wallpaper.
- Syndicate: You (Eurocorp) and all the other Syndicates are trying to Take Over the World though this and cyborg-manned force. Civilians all have a chip in their heads that does all the functions of a phone or computer, and makes the world look far more pleasant. In Syndicate Wars, Eurocorp has been maintaining the mind control conspiracy for years.
- Call To Power gives you the option of doing this to your citizens if you're so inclined.
- Stellaris has orbital mind-control lasers as an actual spaceport component available to authoritarian empires.
- An episode of Stroker and Hoop involved a case where a client thinks Ron Howard is reading his thoughts and controlling his actions via satellite. He was right, by the way — this turns out to be how Ron Howard gets people to see his movies.
- Avatar: The Last Airbender does not have one, no matter what anarchist propaganda the Gaang may preach about the honourable guardians of justice, the Dai Li. But why are we bothering you with all of this distressing talk? The Earth King has invited you to Lake Laogai- and you are, of course, pleased to serve him. And do remember- there is no war in Ba Sing Se. There is no war in Ba Sing Se. There is no war in Ba Sing Se.....
- The Simpsons episode "The Computer Wore Menace Shoes" has Homer create a lie for his blog saying that flu shots control the minds of children. Later, Homer is captured and taken to a mysterious island because his lie turned out to be true, as flu shots are given before Christmas so people will get the urge to shop.
- There are plenty of people out there who think they're being influenced by Orbital Mind Control Lasers or that the CIA has implanted radio receivers in their molars. Seriously.
- Aileen Wuornos was quite a firm believer that the prison was beaming signals into her head to stop her from revealing the big conspiracy, that the police knew she was going to be a serial killer and were just trying to earn money through movie deals. Yes, she was insane.
- One disturbed person sued the State of New Jersey for this, in Searight v. New Jersey, 412 F.Supp. 413 (D.N.J. 1976). The complaint was dismissed mainly on grounds of jurisdiction, but the court's opinion noted, even if the facts were as pleaded, "Searight might have pinned to the back of a trouser leg a short chain of paper clips so that the end would touch the ground and prevent anyone from talking to him inside his brain." Not quite a Tinfoil Hat, but close.
- Possibly the first example: an Englishman named James Tilly Matthews was imprisoned in Bedlam hospital in 1797 and began to claim that a gang of "pneumatic chemists" were using an "air-loom" to control his mind and keep him locked up.
- An honest and sincere belief that there is a massive global conspiracy of some sort targeted specifically at the sufferer is one of the defining symptoms of paranoid schizophrenia, along with a general disconnection from reality, selective memory to the extent that the sufferer will have memories of things that never happened, and often extremely powerful visual and auditory hallucinations (voices in your head, visions of things that never happened, etc). This can be an utterly horrifying experience for both the sufferer and for their loved ones who will often be accused of being in on it, whatever it is.
