The writing gap — Ink against the human page, by code and by reading study · 2026-09-10

Three instruments, run over the same two corpora: 88 English Ink pieces (79,502 words, every public edition 09-04 → 09-10) against the 267-piece majors bank (338,621 words). One: disproportion finders over everything — every word, two-word phrase, sentence shape, opener and title scored by how far its rate in Ink sits from its rate in the majors, nothing named in advance. Two: an LLM counting ten habits with quotes over 33 Ink pieces and 30 majors, so a habit code cannot see gets a number anyway. Three: four editors reading 40 matched human/Ink pairs with no list given — just「name every difference a reader would feel, with the sentence that shows it」— and their notes merged afterwards into one catalogue of 29 habits.

1 · The diagnosis

reader 1, unprompted「Ink writes essays about its subject; the humans write from inside it. Every Ink piece knows its own thesis before the first sentence, announces its structure, defines its terms, restates its claim at every landing, and closes on a rule. Human pieces wander, joke, admit failure, quote a stranger, leave a question open, and stop when they run out of things to say.」

Three of the four readers opened with the same habit, and the code found the same thing from the other end. The register is present-tense, definite and certain: twice the is, half the but, half the was — Ink states where a person narrates and concedes. The single most over-used sentence in the language of Ink is the short copular declarative with the, it or that as its subject —「That is the whole game.」— at seventeen times the human rate, and the human sentence it replaces opens on a named subject, runs past twenty words, and is allowed a dash or a question.

Two things follow from that, and they are the two the readers felt first. Every paragraph must land. No Ink paragraph stops on a fact, an image, a half-thought or a shrug; the last sentence is always a short, symmetrical, quotable restatement of the paragraph above it, so the reader is never left to draw the inference. Over a whole piece it is a metronome with a cymbal on every bar, and the reader stops believing any of them. And nobody real is in it: no room, no hour, no weather, no body, no overheard speech. Sources arrive with full institutional titles, lifted from the news brief; supporting characters are categories rather than people. No Ink persona ever stands next to anyone.

Two corrections to the first cut, both from the code: paragraph endings are not a tell by length (30% of Ink paragraphs end on a sentence of ten words or fewer, against 31% of the majors' — what differs is what the short sentence does), and humans use more hard metaphors than Ink, not fewer. Both are in §4.

2 · The catalogue — 29 habits, four readers, 40 pairs

Each reader ranked what they found over their own ten pairs; a habit's count is the sum across the four, so the maximum is 40. The same habit under four names has been collapsed into one row. Ranking is by how strongly the readers said the habit marks a piece as machine-written, then by pair count.

The top eight, in full

The Ink sentence on the left with its persona, the human sentence on the right with its author, and one line under each on what the difference is.

1 · the paragraph must land — Ink, Thomas Feddo「A crate of vodka is not a lever.」
The paragraph's own summary, short and symmetrical, handed to the reader so no inference is left to make. Every paragraph in the piece ends this way.

1 · a paragraph that just stops — Bradbury「Denver's stadium costs are not yet known.」
A fact, unresolved, in terminal position. The reader is trusted to hold it and read on.

2 · the move is announced — Ink, Phil Knight「Scorecard first. That's the honest order.」
The outline is left standing in the finished building: the piece tells you where you are in the argument before it makes it.

2 · the answer begins inside the answer — Paul Graham「Probably for the same reason that few hackers take up painting.」
No stage direction. The sentence is already the argument, and the reader picks up the thread mid-stride.

3 · nobody real — Ink, Darwin「Dr Elver Luiz Mayer, of the Federal University of the São Francisco Valley, examined the remains.」
A source with a full institutional title, lifted from the brief. Nobody the writer met, nothing overheard, no room.

3 · somebody real — Osterman, quoting a manager「Temp workers: We don't need them. Wait a day for turnover.」
A person the writer stood near, in his own words, saying something the writer would not have written.

4 · the closing sermon — Ink, Warren Buffett「simply ask to see his test results.」
The last paragraph turns into homework: a rule, a protocol, a list of things to watch.

4 · the borrowed last word — Steinem, at the close of her obituary「I'm keeping my torch, thank you very much.」
The piece ends on somebody else's line and takes no position at all. Nothing is asked of the reader.

5 · not this, but that — Ink, George Orwell「There is no ladder. There is simply a stretch of water.」
The claim cannot be made without denying its opposite in the same breath. It sounds like a thought and costs nothing — the English cousin of 不是…而是….

5 · the same move, spent once — Adam Gopnik「sleep is not a neat off-and-on switch but a fully human and fiendishly manifold activity」
Humans do use it. Gopnik uses it once in 827 words, where the distinction actually carries the paragraph.

6 · nothing is wasted — Ink, Mark Twain「each was an engine wound up by the other's tariff, and the gears did the rest.」
The fable is decoded in the sentence after it is told. Every sentence is load-bearing, which is itself the tell.

6 · the sentence that serves nothing — Youngflesh「a small makeshift lab on a ship in the Antarctic, which likely smells of penguin guano to this day.」
A joke that does no work for the argument and is not explained. The writer spent something for the reader's pleasure.

7 · intensifier wash — Ink, Jony Ive「relentless, rigorous, invisible care across every single millimeter」
A coat of adverbs and adjectives over unchanged briefing prose. Two dialects, one habit: literally · basically · insane for the casual personas, utterly · profoundly · singular for the formal ones.

7 · heat from flat delivery — Ian Frazier「We now live in a country with more than seventy million completely insane people.」
One intensifier, load-bearing, in a sentence otherwise plain. The shock is in the claim, not in the adverbs.

8 · never wrong — Ink, Jony Ive「I have learned to trust that intuitive reaction far more than any technical document.」
No false start, no changed mind, no admitted error, no grudge. The narrator is serene from the first sentence to the last, and everybody in the piece is treated kindly.

8 · something at stake — Paul Graham「I can't prove that one should do this.」
The writer gives away a weakness in his own argument, in the middle of making it. Reader 4 could not find one of these in ten Ink pieces.

3 · By code — the register from four directions

The instrument is the log-odds ratio with an informative prior (the「fightin' words」method), z-scored so a rare word cannot win by luck. Nothing was named in advance. What came out is not a list of words; it is a register, and it reads the same whether you look at words, phrases, sentence shapes or openers.

Words — 25 over, 15 under (per 10,000 words)

Two families and one leak. The intensifiers of certainty — exact · real · true · single · never · nobody · merely · simply · must · cannot — are a performed confidence, five to eight times the human rate each. The formal default — whether · upon · remains — is the machine's untuned English. And machine · market · says plus, below the cut, reader · headline · phrase · sentence · narrative are the brief's own vocabulary leaking through. The words Ink is short of are the words of a person: my · people · was · it's · I'm · some · other · all.

Two-word phrases — 15 over, 10 under (per 10,000 words)

over-used	Ink	majors	under-used	Ink	majors

the whole	6.6	1.6

the report	3.7	0.2

The same register one word wider: the copular claim (that is · is the · is a · it is) against the human's past-tense first person (I was) and the plain verbs of doing (want to · to get · to do). Three uses of「the best」in 80,000 words: Ink does not rank, recommend or enthuse.

Sentence shapes — 10 over, 10 under (per 10,000 sentences)

A shape is opener class | length band | mark: what the sentence starts with (a name, the, it, that, something else), how long it runs, and whether it is copular (is/was/are as its main verb) or carries a dash or a question mark.

over-used shape	Ink	majors	under-used shape	Ink	majors
「That …」≤ 8 words, copular	152	9	a named subject, 21+ words	311	636
「The …」≤ 8 words, copular	237	45	any other opener, ≤ 8 words	70	239
「That …」9–20 words, copular	121	10	a named subject, 21+ words, with a dash	12	127
「A …」≤ 8 words, copular	47	4	a named subject, 9–20 words	759	1016
「The …」≤ 8 words	348	65	opening on in, 21+ words	43	104
「The …」9–20 words	656	245	a named subject, ≤ 8 words, a question	10	55
「A …」9–20 words	233	67	a named subject, 9–20 words, with a dash	6	51
「It …」≤ 8 words	136	27	any other opener, 9–20 words	97	169
「The …」9–20 words, copular	290	117	opening on as, 21+ words	8	49
「It …」9–20 words	175	65	opening on and, 9–20 words	35	83

This is the owner's「X is X. X isn't X」, found rather than assumed. The short copular declarative with a pronoun or the as its subject is the most over-used shape in Ink at 17×; the human sentence it replaces opens on a named subject, runs long, and is allowed a dash (10×) or a question (5×).

Sentence openers — the first two words (per 10,000 sentences)

over-used	Ink	majors	under-used	Ink	majors
That is	252	7	There are	4	42
I have	135	24	If you	43	83
It is	141	36	I was	14	43
There is	62	15	At the	4	23

That's the	23	3	For example	0	21
I read	22	2	When I	14	30
You cannot	20	2	And yet	2	14

Ink never says for example, in fact, of course, I think, and yet — the small spoken moves a person uses to concede, illustrate and soften. It opens on the verdict instead:「That is …」, thirty-six times the human rate. And it opens on itself: Let me · Here is · The report · I read are the stage directions of §2's habit 2, caught by the code as openers.

4 · What the counts say is real, and what they clear

The disproportion finders see only what the corpus repeats. So a second instrument read 33 Ink pieces and 30 majors and counted ten habits with quotes, one at a time. Four of the ten are real tells by count. Four are not — and two of those were on the owner's own list, which is why the count was worth paying for.

habit	Ink /1k	majors /1k	×	verdict
D1 · a number spelled out —「at a depth of eight metres — upwards of twenty-six feet」	1.74	0.41	4.2	a real tell
F · stiff or certainty vocabulary —「calling the meltdown entirely beyond their control」	3.85	1.49	2.6	a real tell
B · a thing speaks or knows —「The machine swallows all that desperate intent」	1.89	0.85	2.2	a real tell
E · a disclaimer or hedge —「I'm no foreign correspondent, but…」	1.19	0.55	2.2	a real tell
C2 · a metaphor that works —「the invisible traffic cop」	1.81	1.51	1.2	matched; not a tell
D2 · a round number as colour —「another two living out of a roller bag」	0.70	0.61	1.2	matched; not a tell
A · a flat verdict sentence —「There is zero cushion.」	5.37	4.10	1.3	cleared — Graham writes「Speed defines startups.」
D3 · false precision —「in five minutes, and it'll take the market years」	0.22	0.22	1.0	cleared — identical rates
G · the explaining reflex —「Here's what civilians fail to grasp…」	1.56	1.71	0.9	cleared — humans explain slightly more
C1 · a metaphor that makes it harder —「an unforgiving spreadsheet with jet engines」	1.15	1.85	0.6	cleared — humans use more of them

read this one twiceThe flat verdict sentence is not a machine tell by count (1.3×), and the hard metaphor is a human habit (Ink uses 62% as many). What separates Ink is not that it makes hard figures or flat statements — it is where it puts them: every paragraph's last sentence, every time. The readers of §2 called this from the other side —「no paragraph is allowed to end flat, trail off, or leave the reader to draw the inference」. Position, not rate. That means the fix is a rule about paragraph endings, not a ban on short sentences or on metaphor.

The regex first cut, kept for comparison (09-09/09-10 editions only, already on the plan page): sentence length is matched at 17.5 words against 17.9 — so length is not where the gap lives. Contractions half the human rate; questions a third; exclamations none; dashes a fifth. Metaphor nouns 2.5 per 1k against 0.9–1.6. Disclaimers 0.45 a piece against 0.15. Paragraphs 109 words against 50–69 — the wall. The two instruments agree on disclaimers and disagree on metaphor: the regex counts metaphor nouns, a vocabulary measure; the LLM counted figures that work and figures that don't, and the ones that don't are ours by a factor below one.

5 · Titles

By close reading of every title in both corpora: 37 of 88 Ink titles (42%) turn on a negation, an absence or a failure, against 56 of 267 human titles (21%). By the wide keyword lexicon the same measure reads 28% against 10% — the lexicon undercounts Ink, because the frame is often carried by no keyword at all. The second gap is quieter and larger: a title that is simply a noun phrase — no verb, no argument, a name for the thing — 19% of Ink titles against 46% of human ones. Human titles are flat, borrowed, or a found phrase (「What to Do」;「'I hate everybody including you'」). Ink's state the argument and twist it, in one shape, over and over.

6 · What Ink does well

All four readers volunteered this without being asked for it.

Sourcing. Names, dates, numbers and quotes are dense, accurate and correctly attributed —「better than several of the human pieces」(reader 1). Ive's fifteen removed brackets and 0.2mm support plane; MrBeast's fifteen launch windows; Didion's shot-by-shot inventory of the tape.
The costly personal specific is the best thing in the piece, every time it appears.「I bought my home on Farnam Street in 1958 for $31,500 and I reside there still.」(Buffett) ·「I doubled sales every year in the 1970s and was broke every year, because I shoved every dollar back into the next pair of shoes」(Knight) ·「I passed several days upon my knees beneath a low cliff of reddish clay and gravel」(Darwin).
Honest uncertainty about the world — as distinct from performed modesty about the self.「I had no true comprehension of what I had gathered.」(Darwin; reader 3:「the one moment of admitted ignorance in the batch… that is the register the other nine never reach」) ·「Scientists did not tell half the people to eat aspartame and half to turn away from it. They watched.」(Oprah).
Real arguments, not paraphrase. Tao on the difference between a proof and a statement; Doyle on what a libel court can and cannot decide; Kumar on the white primaries; Holmes on the tell of the volunteered denial.
One unlabelled homely figure, when it comes.「The patient is bled to soothe the physician.」(Keynes) ·「A noun will not halt a caterpillar tractor, rebuild a smashed cottage, or put a peasant back in his field.」(Orwell) ·「shame wearing a white lab coat」(Oprah).
Two pieces pass outright. Reader 2 on Phil Knight (pair 20):「contractions, one-line paragraphs, a quote left deliberately ungrammatical, a real failure admitted flatly… the only Ink piece in the batch that lets a sentence be imperfect」. Reader 4 says the same of the Ephron letter (pair 36):「this is what Ink looks like when it works」.

7 · What this feeds

Three things, all on the writing loop. The critic's anchors (lib/ink/critic.md) take their「this works / this doesn't」pairs from §2's top eight, so a deduction means the same thing in every loop. The writer's example sheet (lib/ink/shelf-sentences.json) takes the right-hand column — whole human paragraphs keyed to the habit they answer — because demonstration beats a rule. And the loop's code audit (lib/ink_tells.py) is §3 and §4 recomputed every loop, with the majors' rate as each finding's allowance, so the list is never hand-kept: the four cleared habits are dropped from it today, and the paragraph-ending rule replaces the flat-sentence ban. Every loop's row lands on the ledger.
