E Epiphany · the ten bits and the great code
A self you cannot see from inside
Before this argument goes further, it has to clear away a piece of folklore that would have made the case easier and false.
Motivational literature has repeated for a century that human beings use ten per cent of the brain. Neuroscience has demolished the claim. Barry Beyerstein of Simon Fraser University spent years documenting the evidence against it. Decades of deep brain stimulation have probed the whole organ and turned up no dormant nine-tenths. The metabolic arithmetic finishes the argument: the brain accounts for two per cent of body weight and consumes around twenty per cent of the body's resting oxygen. Evolution does not build and heat an organ that expensive and then leave nine rooms empty.2 Any writer who reaches for the ten per cent line reaches for a comfort, not a fact.
The real evidence runs stranger, and it cuts far deeper.
Ten bits a second
In December 2024, Jieyu Zheng and Markus Meister of the California Institute of Technology published a paper in Neuron with a title that could sit on the spine of a novel: The unbearable slowness of being. Zheng applied information theory to a century of studies on human behaviour, from reading and typing to competitive Rubik's cube solving and memory contests. She arrived at a number that she herself refused to accept at first.1
Human senses gather data at about one billion bits per second. Human conscious throughput runs at ten bits per second. The gap between the two spans a factor of one hundred million.
Ten bits a second. The senses deliver a billion. A person meets the world through a keyhole one hundred million times narrower than the doorway.
After Zheng and Meister, Neuron, 2025
Zheng and Meister describe two systems. An outer brain handles the torrent, at enormous width and speed. An inner brain distils that torrent into the handful of bits that steer a decision. Almost everything a person registers therefore passes through them and vanishes without ever reaching the narrow channel where they experience themselves thinking.
That number reframes the whole question of self-knowledge. A person does not fail to use the brain. A person operates a magnificent brain through a keyhole.
Telling more than we can know
A second body of evidence closes the trap. In 1977, Richard Nisbett and Timothy Wilson published a review in Psychological Review that has since gathered more than thirteen thousand citations. They gathered study after study in which researchers manipulated the true cause of a person's choice, then asked the person to explain that choice. The explanations came back confident, fluent, and wrong.3
Their conclusion holds today: people have little or no direct introspective access to their own higher-order mental processes. When someone explains why they chose, preferred, or reacted, they do not read off an inner record. They construct a plausible story from private theories about what causes what.
Put the two findings together. The channel runs at ten bits. The narrator inside that channel invents its own causal accounts. William James saw the shape of this in 1907, long before anyone could measure it. He wrote in The Energies of Men that we make use of only a small part of our possible mental and physical resources.2 Later writers corrupted that line into the ten per cent myth. James had it right in the first place, and the modern instruments have made his claim larger rather than smaller.
Why a conversation reaches what reflection cannot
A person cannot inspect the inner brain. A person can, however, put sentences into the world and watch what comes back. Language carries the ten bits outward, where they take a shape a person can examine, contradict, and revise. Every diary, confession, therapy hour, and long letter has worked on this principle. The Lucas experiment supplied the missing variable in 2014: strip the judging listener out of the exchange, and people surrender more of what they carry. Sara Weisband and Sara Kiesler found the same effect across 39 studies of computer-administered questionnaires, which drew fuller disclosure than face-to-face interviews long before anyone trained a language model.5
The great code
Now to the second half of the epiphany, and to a Canadian who mapped this territory decades before the machines arrived.
Northrop Frye taught at Victoria College in Toronto, served fifty-five years as a minister of the United Church of Canada, and lies buried in Mount Pleasant Cemetery. In 1982 he published The Great Code, borrowing his title from William Blake's engraved aphorism that the Old and New Testaments form the great code of art. In 1990, months before his death, he completed the companion volume, Words with Power.11
Frye's governing claim ran against common sense. Literature, he argued, comes out of literature. The poet works inside a verbal universe built by earlier poets. The whole Western imagination organises itself around one structural code of myth, metaphor, and archetype that the Bible supplied. A writer who reaches for an image reaches into that inheritance whether or not the writer knows the debt.
Primary concerns must become primary, or else.
Northrop Frye, Words with Power, 1990
Frye drew a further distinction that this paper needs. He separated primary concerns from secondary ones. Any work of literature, he wrote in Words with Power, will reflect the secondary and ideological concerns of its time, but it will relate those concerns to the primary ones of making a living, making love, and struggling to stay free and alive
.11 Food, shelter, love, freedom, survival. Ideology sits above them and depends on them.
Apply Frye to the machine and the picture sharpens.
A language model trains on the human archive. Books, letters, arguments, scriptures, court transcripts, jokes, laments, manuals, poems, and the ordinary chatter of billions of people. That corpus works as a secular great code. When the machine writes a story that nobody has read before, it does not import novelty from outside the human record. It recombines the code. The apparent originality rises from the sheer depth of the reservoir and from the strange angles at which the machine cuts through it.
This claim carries an empirical fingerprint, and researchers have found it.
Anil Doshi of the UCL School of Management and Oliver Hauser of the University of Exeter ran 300 writers through a controlled experiment. Science Advances published the result in July 2024. One group wrote short stories unaided. Other groups received story ideas from a language model. Evaluators rated the AI-assisted stories as more creative, better written, and more enjoyable, and the gain landed hardest among the writers who had entered the study with the lowest creativity scores. Then the researchers measured the stories against each other. The AI-assisted stories resembled one another far more than the unaided ones did.12
300Writers in the Doshi and Hauser experiment, Science Advances, July 2024
↑Individual creativity ratings rose, most sharply among the least creative writers
↓Collective diversity fell. The stories converged toward one another
Doshi and Hauser call the pattern a social dilemma: each writer gains, and the culture loses range. Read it through Frye and it reads as something else as well. Convergence toward a common centre marks the exact signature of a recombining archive. The machine does not invent a new imagination. It redistributes an old one, and the redistribution pulls toward the middle of the code.
Narcissus and the portrait painter
One philosopher has already claimed the mirror, and she uses it to warn rather than to invite. Shannon Vallor holds the Baillie Gifford Chair in the Ethics of Data and Artificial Intelligence at the University of Edinburgh and previously served as an AI ethicist at Google. Her 2024 book The AI Mirror argues that these systems reflect human intelligence without possessing any, and that the reflection points backward. Trained on the accumulated data of the human past, they show a person where the record says humanity has already stood, never where it might venture for the first time. She opens with Ovid's Narcissus, who fell in love with his own reflection in the pool and starved beside it.13
Vallor argues well and this paper concedes her central point. The mirror does point backward. Nothing in the training corpus reaches past the last human sentence anyone wrote down.
Her warning, though, describes one posture only. It describes the gazer.
Two people can stand at the same glass. Narcissus looks, and keeps looking, and dies of looking. A portrait painter looks, and picks up a brush, and makes something that did not exist that morning. The glass performs the identical service for both. The variable never sat in the mirror. It sat in the hand.
A backward-facing record supplies the only material any author has ever had. Memory points backward. So does every archive, every photograph, every scar.
The answer to the Narcissus warning
Frye's great code points back three thousand years, and every forward-facing writer in the West cut new work out of it. A camera captures only what already happened, and film-makers build futures from the footage. A person's own memory contains nothing but the past, and yet a human being remains the only creature that can take that backward record and compose a life forward from it.
So the question shifts. Stop asking which direction the mirror faces. Ask who stands in front of it, and what that person does next.
Angels, aliens, and where the parallel breaks
Human beings have rehearsed this encounter for millennia. For most of recorded history, cultures have organised themselves around intelligences they could not match: gods, angels, ancestors, powers. Theology built an entire grammar for standing in front of something greater without collapsing, a grammar of awe held together with agency. The pattern deserves attention now, because the emotional signature repeats. People meet a capability that outruns them and they oscillate between terror and appetite.
The parallel earns its keep, and then it breaks at a joint that matters.
An angel carries intent. A mirror carries none. A language model wants nothing, plans nothing, and holds no view about the person typing. Whatever intent surrounds these systems belongs to the companies that build them and the people who deploy them. Dario Amodei, who leads Anthropic, put that fact on American network television in November 2025. Anderson Cooper asked him who elected him and Sam Altman. Amodei answered: No one. Honestly, no one.

That answer relocates the moral question, and it relocates it to exactly where Vallor puts it. The danger sits with the humans holding the glass, not with the glass. Which returns responsibility to the reader, and to what a person does on an ordinary morning.
