You Heard the Word Once. Now It's Everywhere. Your Mind Is Lying to You.
You hear a word for the first time at breakfast — a diagnosis, a band name, a term someone drops in a group chat. By Thursday it's on a billboard, in a text from your sister, out of a stranger's mouth on the train. It feels too exact to be chance. It feels like the universe leaned in and started talking directly to you.
It didn't. Your attention did something, and it's worth knowing exactly what, because the feeling it produces — this is a sign — is one of the more persuasive lies your own mind tells you, and it tells it constantly, about everything from car models to symptoms to people's names.
The name has a stranger origin than the phenomenon itself
In 1994, a reader named Terry Mullen wrote into the "Bulletin Board" column of the St. Paul Pioneer Press describing something he couldn't shake: he'd mentioned the West German militant group Baader-Meinhof once, and then encountered the name again within twenty-four hours, out of nowhere. Other readers wrote in with their own versions of the same experience. The column ran with it, and the name stuck as shorthand for years before anyone gave it academic footing — a phenomenon named by a newspaper comment section, floating around undefined for over a decade.
That changed in 2005, when Stanford linguist Arnold Zwicky wrote about it on the linguistics blog Language Log and gave it a formal, portable name: the frequency illusion — "a quirk of perception whereby a phenomenon to which one is newly alert suddenly seems ubiquitous." By 2019, the term had made it into the Oxford English Dictionary. What started as one man's letter to a newspaper became a documented feature of how human attention actually works.
Your brain didn't start noticing more. It started filtering differently
Here's the mechanism, and it's simpler and more mechanical than the eerie feeling it produces. Zwicky identified two processes running in sequence, each one feeding the next.
First: selective attention. Your brain cannot process everything in your visual and auditory field at once, so it runs a constant triage, deciding in real time what's worth flagging. The moment something becomes personally relevant — you just bought that car, just heard that diagnosis, just learned that word — your attention system reclassifies it as high-priority. It was always in your environment at roughly the same rate. You just never had a reason to flag it before.
Second, and this is the part that turns a filtering quirk into something closer to a trap: confirmation bias. Once your attention starts flagging the thing, you start unconsciously looking for it, and every instance you find reinforces the sense that something significant is happening. The two processes lock together — selective attention opens the gate, confirmation bias keeps it propped open — and the result is a completely convincing illusion that the world rearranged itself around you.
The classic, almost universal example is the car-buying one. You purchase a specific model, and within a week it feels like everyone on the road is driving it. Sales didn't spike. Your filter did. The same thing happens to people expecting a child — suddenly pregnant women appear to be everywhere they look — and to anyone who's just learned a new piece of vocabulary, a new symptom, a new fear.
The eerie feeling is the tell, not the evidence
This is where the illusion does its real damage, and it's not really about car models. It's about what happens when the "thing you're suddenly noticing everywhere" is a red flag — about a partner's behavior, a health symptom, a coworker's tone — instead of a Volkswagen. The same mechanism that made you notice a curse word suddenly appearing everywhere will make a single suspicious pattern feel like it's confirming itself constantly, because your attention is now scanning specifically for it and your confirmation bias is logging every near-match as a hit. The feeling of this can't be coincidence, it's too exact isn't proof of anything except that your filter changed. It's the exact texture of a mind that's found something to worry about and is now actively, invisibly, hunting for confirmation.
That doesn't mean the pattern is imaginary. Sometimes what you're noticing really is real and really was there all along, hiding in plain sight until your attention got pointed at it. The frequency illusion doesn't tell you whether the underlying thing is true — it just tells you that your sense of how often it's happening is not a reliable measurement, because the measuring instrument is compromised by the exact moment you started caring.
Say the sentence that undercuts the spell
There's a specific reframe that works here, and it's not about dismissing what you're noticing — it's about correctly attributing where the "everywhere" feeling is coming from. My attention changed. The world did not. This is not fate, and it is not a sign. This is my own mind proving that it's paying attention — which is useful information about my own mind, and separate information from whatever I think I'm tracking out there.
Enjoy the pattern when it shows up. Let it flag things worth a second look. Just don't hand it the authority of destiny. You are not chosen, and you are not cursed by a universe conspiring to send you messages through billboards and group chats. You're a person whose filter got pointed somewhere, doing exactly what filters do — finding more of whatever they've been told to look for.
The next time something feels like it's following you, ask the boring question before the dramatic one: what did I just start paying attention to?
