Black Mirror’s Mandela Effect Episode Will Have You Questioning Your Reality — Literally

The latest season of Black Mirror is back, and it’s every bit as unsettling as fans have come to expect. But one episode in particular — Bête Noire — is giving viewers a fresh kind of existential dread. Instead of merely warning us about AI or simulated worlds, it nudges us toward something closer to home: our own faulty memories.

Don't worry, there are no spoilers ahead, only teasers. Trust me, the episode gets way stranger towards the end than what we're going to discuss here.

In Bête Noire, we meet Maria (played by Siena Kelly), a seemingly regular employee at a candy company. Her life takes a strange turn with the arrival of Verity (Rosy McEwen), a former schoolmate whose presence begins to unravel Maria’s sense of reality. As Maria struggles to remember what she wrote in emails or the names of familiar places, a disturbing possibility emerges — what if Verity is somehow altering reality?

How Did Mandela Effect Turn Up On Black Mirror?

The episode’s most unsettling moment comes over something as innocent as a fried chicken joint. Maria recalls frequenting a place called "Bernie’s.” Not just that — her boyfriend worked there for a year and even had a cap to prove it. She's absolutely sure of the name. Then, during a casual office chat, a co-worker gets into a verbal tiff with her: "It’s Barnie’s.” Maria, confused, doubles down. Even Verity sides against her. So, naturally, the team Googles it. Every search result? Barnie’s. Maria rushes home, checks her boyfriend’s old cap… and there it is, embroidered in all-caps betrayal: "BARNIE’S.”

Cue existential crisis.

Mandela Effect: Fictional Plot Or Psychological Phenomenon?

Turns out, this bizarre episode isn’t purely science fiction. The mental slip Maria experiences is a very real cognitive quirk known as the Mandela Effect. Coined by researcher Fiona Broome, the term originated when she, and many others, mistakenly recalled Nelson Mandela dying in prison in the 1980s. In truth, Mandela was released and went on to lead South Africa, passing away in 2013.

Broome noted that she remembered international coverage of his death. This collective misremembering of an event that never happened gave birth to the term now widely used to describe shared false memories.

Your Brain Is Lying To You — And Here’s The Proof

Still not convinced you’ve fallen for the Mandela Effect? Let’s play a quick round of "Wrong, but Confident”:

  • Monopoly Man – Got a monocle, right? Wrong. Never had one. You’re thinking of Mr. Peanut.
  • "Rishte me toh hum tumhare baap lagte hai" - Papa Shahenshah never said "baap lagte hai," he said "baap hote hai"!
  • Looney Toons – Makes sense since it’s cartoons? Nope. It’s Looney Tunes.
  • The Flintstones – That extra "t” you never noticed? It was always there. It’s Flint-stones, like the rock.
  • Thums Up – Yep, your favourite toofani drink was never called Thumbs Up, despite the misleading logo.
  • "Luke, I am your father." – Lord Vader never said that. The real line is, "No, I am your father.”
  • Mickey Mouse – No suspenders. Never had them. Not even in the classic "Steamboat Willie." Your memory added accessories for flair.

See what’s happening here? Your brain likes to fill in the blanks — often with pure nonsense.

So Why Does This Happen?

Memory isn’t a filing cabinet — it’s more like Wikipedia. Anyone (including your own brain) can edit it.

Psychologists point to false memories, which can be triggered by suggestion, social pressure, or just your mind trying to make sense of chaos. Sometimes they’re close to the truth — other times, they’re completely fabricated. In some studies, people have been convinced they committed crimes that never occurred. That’s how pliable our memories can be.

So when Maria is gaslit by the entire internet over a fried chicken logo, it’s not just chilling fiction — it’s a painfully accurate metaphor for how fragile our grip on "truth” really is.

Black Mirror has always asked what tech might do to humanity. But in Bête Noire, it asks something scarier: What if you can’t trust your own mind? Turns out, the scariest dystopia might just be the one inside your head.
