Something in the Air

It happens to everyone, and almost no one talks about it without lowering their voice. You turn over a thought you have never had before — a phrase, a business idea, a way of seeing something — and within a week it is everywhere. A friend messages you the same joke you were about to send them. Three people you follow post the identical take on the identical morning. You learn a strange new word and then trip over it four times in two days. It feels, honestly, like telepathy. Like there is something in the air.

In the last essay I argued we are in a Fourth Turning — a crisis season — and that it is, underneath, "a contest of narratives" that spread "like contagions." A few of you wrote back with a fair question: how? How does a mood or an idea get into so many heads at the same time? And why does it feel less like reading the news and more like tuning a radio?

I want to answer that properly, because it is the thing I find most quietly astonishing about being alive right now. I am also going to do it without a single crystal. The feeling is real — it is data, not delusion. The popular explanation for it — a shared field, a collective consciousness humming on some electromagnetic plane we all plug into — is a hypothesis, and as far as the evidence goes, not a good one. But here is the twist that makes this worth an essay: the real explanation is a connection just as literal, and far stranger than the mystical one. We genuinely are wired together. Not through the ether. Through something we built.

First, it really isn't just you

Start with the cleanest evidence, because it predates the internet by centuries and so cannot be blamed on it. In 1922 two sociologists, William Ogburn and Dorothy Thomas, published a paper with a wonderful title — Are Inventions Inevitable? — and a list of around 150 cases where the same discovery was made independently, by different people, at nearly the same time. Calculus. Natural selection. The telephone, filed by two men at the same patent office on the same February day in 1876. The sociologist Robert Merton later argued that this — the multiple — is not the weird exception in science. It is the norm. The lone genius having a private lightning strike is the story we tell; the reality is usually a crowd arriving at the same door within a few years of each other.

Once you have seen the pattern you cannot unsee it, and it reframes the eerie feeling completely. When you and a stranger have the same idea in the same month, you are not picking up each other's brainwaves. You are both standing in the same place in the landscape of what is currently thinkable, looking at the same open door. The spooky part is not that two people walked through it. It is that the door only just appeared — and it appeared for both of you at once.

Why the door appears: the adjacent possible

The biologist Stuart Kauffman gave that door a name: the adjacent possible. At any moment, given the ideas and tools that already exist, there is a set of next steps that have just become reachable — recombinations of things lying around. You cannot invent the search engine before the web, or the meme before the phone camera. But the moment the ingredients are all on the table, the next dish becomes cookable, and it becomes cookable for everyone standing at that table at the same time.

This is why discoveries cluster, and — crucially — why they accelerate. The economist Paul Romer won a Nobel for the observation that ideas are unlike other goods: they are non-rival, meaning we can all use one without using it up, and they recombine. Every new idea becomes a fresh ingredient in someone else's recipe. W. Brian Arthur made the same case for technology: it evolves by combining existing pieces into new wholes. So the pile of ingredients does not grow steadily — it compounds, because each new piece multiplies the number of possible combinations. More adjacent possible means more simultaneous discovery. The "something in the air" is getting thicker every year, on purpose, and we are the ones thickening it.

An honest aside, because not everything in the air is real

I promised no woo, and that cuts both ways — I also have to police my own pattern-matching. Some of the uncanny feeling is a trick of attention. There is a well-documented quirk called the frequency illusion, or the Baader-Meinhof phenomenon: the day you learn a word, your brain — now primed — starts noticing every instance it used to filter out, and mistakes the sudden salience for a sudden surge. Add confirmation bias, and a few genuine coincidences get promoted into a felt cosmic law. The plural of whoa is not data.

And while I am here: the famous "hundredth monkey," where a behaviour supposedly leapt across the sea to islands it could not have reached once enough monkeys learned it, was a fabrication — the story was embellished into folklore and the original researchers described nothing of the kind. Rupert Sheldrake's "morphic resonance," a literal field of memory connecting minds, has never produced replicable evidence. I am not leaning on any of that, and you should be suspicious of anyone who does. The real explanation does not need it. It is sturdier, and it is weirder.

The real "collective consciousness": the collective brain

Here is the reframe that, for me, dissolves the mystery and keeps the wonder. The thing people are reaching for when they say collective consciousness is real — it is just made of ordinary parts. Anthropologists like Joseph Henrich call it the collective brain. His argument, laid out in The Secret of Our Success, is that human intelligence was never mainly about the individual head. A lone human is a mediocre animal. What made us extraordinary is that we think between heads — pooling, copying, correcting, and passing on ideas across a network of people and generations. The unit of genius is not the brain. It is the network of brains, wired together by language, teaching, trade, and writing.

That is not a metaphor and it is not mystical. It is why a modern engineer, no smarter than an ancient one, can build things no individual could ever puzzle out alone: they are running on a vast, inherited, distributed mind. Muthukrishna and Henrich have a lovely phrase for innovation — it is what happens in the collective brain when ideas that were floating separately finally get connected. And once you hold the idea, you find its fingerprints everywhere. The philosophers Andy Clark and David Chalmers argued back in 1998 that your mind already extends beyond your skull into your notebook, your phone, your tools — the "extended mind." Ants coordinate vast projects with no boss at all, leaving chemical traces others build on, a trick biologists call stigmergy — which, if you squint, is exactly what a Wikipedia edit or an open-source commit is. Coordination without a coordinator. A mind without a central self.

So: are we all connected? Yes. Unmistakably, mechanically, measurably. Just not through a field. Through each other.

And we literally fall into sync

Now the part that gives me goosebumps, because it is pure physics. Take a lot of things that each have their own rhythm — pendulum clocks on a shared wall, fireflies in a mangrove, heart-pacemaker cells, neurons, people clapping — and couple them, let each feel the others even weakly, and something inevitable happens. Below a certain strength of connection, they stay a jumble. Above it, they spontaneously snap into step. No leader, no signal to start, no plan. The mathematician Steven Strogatz wrote a whole book, Sync, on this one fact of nature, built on a model by Yoshiki Kuramoto. It is one of the most robust patterns in the universe: sufficient coupling produces synchronization.

Drag the slider. That threshold — the flip from twinkling chaos to a single shared pulse — is, I think, the most important idea in this essay. Because coupling is just another word for how strongly connected we are. And the entire arc of human history, told through one lens, is the story of us relentlessly turning that dial up. Speech coupled a band. Writing coupled strangers across time. The printing press coupled a continent. The telegraph — Tom Standage rightly called it "the Victorian internet" — coupled markets and newsrooms across oceans. Radio and television coupled nations into a single evening. And then we built a machine whose entire job is to crank the coupling to the ceiling.

The machine that turns the dial

Here is the modern engine of "something in the air," and it is not spiritual, it is a recommender system. When a feed decides what reel, what meme, what take to put in front of you, it is running a piece of maths — collaborative filtering — that finds the people most like you and shows you what moved them. Multiply that by a few billion phones and you have a device that computes the adjacent possible of attention and serves the same thought to millions of strangers within the same hour. It synchronizes us, deliberately, at planetary scale and machine speed. Your intuition that "the algorithm aligns everyone through reels and memes" is exactly right, and it is the collective brain hooked up to a stimulant drip.

The honest version has nuance, though, and I will not skip it. The scary phrase "filter bubble," popularised by Eli Pariser, turned out to be only partly supported — a large Facebook study by Bakshy and colleagues found our own choices sort us at least as much as the algorithm does, and several researchers have since argued the sealed-echo-chamber picture is overstated. The better-evidenced effect is not that we each get sealed off, but the opposite and stranger thing: acceleration and homogenization. A 2019 study in Nature Communications by Lorenz-Spreen and colleagues showed that our collective attention now spikes and collapses faster than it used to — trends burn hotter and die quicker, year on year. A 2017 study by Brady and colleagues found that each moral-emotional word in a tweet measurably increased how far it spread. We are not just connected. We are connected through a medium that specifically rewards whatever synchronizes us hardest — outrage, novelty, the perfectly timed joke — and turns the coupling knob a little further every quarter.

So what does it do to us? And has it happened before?

Both of those were your questions, and the answers are "a great deal, in both directions" and "yes, every single time."

The upside of a tightly-coupled collective brain is genuine and I do not want to lose it in the worrying. Synchronization is coordination. It is how a scientific community sequenced a new virus and shared a vaccine design in weeks; how open-source software — millions of strangers, stigmergy at scale — quietly runs the modern world; how disaster relief self-assembles overnight; how a hashtag can drag a hidden injustice into daylight in a fortnight. When the collective brain fires together, it can do things no institution could plan.

But synchronization has a cost that every engineer knows in their bones: a system that is too tightly coupled becomes fragile. Sync reduces diversity, and diversity is precisely what made the collective brain smart in the first place. The complexity researcher Scott Page has shown, with actual models, that a diverse group of decent problem-solvers routinely beats a uniform group of brilliant ones — variety is not decoration, it is the compute. So when everyone reads the same feed, laughs at the same meme, and fears the same thing on the same morning, we get the pathologies of a monoculture: bubbles and bank runs, flash crashes, moral panics, manufactured consensus, the whole crowd lurching as one and then lurching back. A forest of identical trees burns beautifully.

And yes, it has happened before, which is the part that ties this back to the Fourth Turning. Every previous crank of the coupling dial produced the same double-edged flowering. The printing press, as the historian Elizabeth Eisenstein documented, did not just spread the Reformation and the Scientific Revolution — it also spread witch-hunt manuals and a century of religious war, because it synchronized Europe's fears as efficiently as its knowledge. My working hypothesis — and this is the piece I have not seen written down quite this way, so take it as mine to be argued with — is that the "turnings" of history are, mechanically, synchronization events of the collective brain. Each new medium raises the coupling, the network flips into a new coherent state, and we get a burst of shared creation and a burst of shared madness, tangled together, until the system re-diversifies and settles. We are living through the sharpest crank yet, which is why the winter feels so loud. We are not imagining the intensity. We can feel the whole network ringing.

Where it goes next, with AI in the loop

Now add the newest node to the collective brain: a machine that has read most of what the brain has ever written, and can write back into it at scale. This is the genuinely new thing, and it points two ways at once — the same fork the last essay ended on.

Pulled one way, AI is the ultimate synchronizer. If a few models mediate most of the writing, code, and images the world produces, they become an averaging filter on human thought — everyone nudged toward the same phrasings, the same aesthetics, the same safe middle. There is even a measured failure mode for this: train models on their own output for a few generations and they collapse, the way a photocopy of a photocopy fades to grey — Shumailov and colleagues call it exactly that. A culture that eats only its own average is a culture losing its variance, which is to say losing the very thing that makes the collective brain intelligent.

Pulled the other way, the same tool is the best instrument for de-synchronizing we have ever had. An AI can translate across bubbles, surface the unlike, hand a curious teenager in a small town the far frontier of the adjacent possible, and be tuned to widen your inputs rather than narrow them. Nothing forces it toward homogeneity except our choice of what to optimise it for. As I keep saying and will keep saying: the tool does not pick. We do.

What to do while the network rings

So here is the practical residue, the part you can actually use, because an essay about being wired together should not leave you feeling like a passive node.

Learn to feel the difference between thinking and synchronizing. When a certainty arrives fully formed and suspiciously well-timed, that is often the network firing through you, not you reasoning — worth a pause. Diversify your inputs on purpose; it is the single cheapest way to become smarter than your feed, because you are manually restoring the variety the algorithm strips out. Guard the weird, local, untimely idea — yours and other people's — because a collective brain that punishes deviation slowly lobotomises itself; the odd note is not noise in the choir, it is the harmony. And build things that add variation rather than just amplification: the world has enough engines for making us the same, and a shortage of ones that help us be productively, generously different.

You were right, is the thing. That feeling of connection is not a delusion and not woo. You are a neuron in a mind that just learned to fire at the speed of light — the most connected the collective brain has ever been, ringing like a struck bell. The only real question, the one this whole series keeps circling, is the one a neuron never gets to ask and we somehow do: not whether we are wired together, but what we choose, together, to think.
