Cross-references updated to the new layout; archive/ references left broken deliberately, as those are historical documents. Also revises chapter 6 of Book One: the notification scene is now four items rather than four hundred, since the narrator is a light user. The low volume is stronger evidence than a flood would have been - it is the case the attention-economy account cannot explain.

This file is the strategic rationale — why the book is shaped this way. For drafting, use
CHAPTERS.md, which is authoritative: it carries the eight-day walk spine, the scene design, the numbered argument beats for every chapter, and the argument ledger. Some chapter titles were revised there and those revisions win.
Each chapter below carries its evidence tier from ../theory/EVIDENCE.md. The tier determines the voice. A Tier C chapter that reads like Tier A is the failure mode this whole restructure exists to prevent.
The spine
Every chapter should be answerable against this sentence: the machinery that decides what matters is being fed information it wasn't built to sort, and the fix is retriage, not abstinence.
Chapters that can't be justified against it don't belong in this book.
Prologue — Seven in the Morning
Tier D (memoir) — and that's fine, it's a prologue.
A war on the other side of the world, in high definition, in your hand, before coffee. You feel it in your body the way you'd feel a fire two streets away. You can do nothing about it. Neither of those facts is a malfunction on its own; together they are.
Set up the question the book answers: not why can't I concentrate, but why do I feel implicated in everything and capable of nothing.
Part I — The Wrong Diagnosis
1. It's Not Attention, It's Relevance
Tier B — the standard account is weaker than people think, and you should say so.
The dominant story: attention economy, dopamine loops, infinite scroll, variable reward. It's not wrong, but note what it can't explain — why a slow-loading text-only news site about a distant famine is also exhausting, why people who successfully quit still feel scattered, why the detox literature is such a mess (96% of studies weak; abstinence performing worst; changing how people use platforms beating quitting).
Introduce the alternative: the problem is upstream of reward. It's the filing system, not the dopamine.
Do not oversell the media-multitasking evidence here — Ophir 2009 mostly didn't replicate and the meta-analytic effect is d ≈ 0.17. Saying so early buys enormous credibility for Part II.
2. The Thrifty Brain
Tier A — the most solidly grounded chapter in the book. Write it with confidence.
Thinking costs energy, so the brain does as little of it as possible. Prediction rather than perception (this is why optical illusions work at all). Heuristics as thrift, not sloth. The cognitive miser. System 1 and System 2. Stereotypes as the same mechanism running on people rather than on edges and surfaces — uncomfortable, but the same machinery.
The consequence that sets up the whole book: a brain this economical must triage. It cannot afford to treat all incoming information as equally important. So it needs a rule for deciding. Chapter 3 is about the rule it evolved.
Part II — The Three Tiers
The original contribution. All Tier C — say so plainly at the top of chapter 3 and the reader will trust you for 200 pages.
3. Within a Day's Walk
Local news: things that affect you directly, that you can verify yourself, that happened close enough to walk to. A neighbour's roof, a flooded road, an illness in the family. Two properties that always travel together — confirmable and actionable. You can check it, and you can do something.
The claim: this is the tier the salience machinery was calibrated on.
4. Within a Day's Ride
Neighbourhood news: indirect effect, arrives through people you know, usually unverifiable but reasonably trusted. Market prices, a dispute in the next valley, who is ill in the next town. Not actionable directly, but it's what context is made of — it's how you know what your local facts mean.
Trust here is social rather than evidential. That's not a flaw; it's the mechanism.
5. Beyond the Horizon
World news: outside any range you'll ever walk, unconfirmable, unactionable. Wars, famines, kings, catastrophes.
The key move of the book, and the one to take slowly: every culture before ours had this tier too, and handled it deliberately. Story, myth, rumour, ballad, sermon. The handling was not a failure to get accurate information. The form was the filing — you knew, from how it arrived, that this was not something to act on today. Distant news came wrapped in the marker of its own distance.
6. The Collapse
The mechanism chapter. Modern media delivers tier-three information carrying tier-one signals: present tense, high definition, real time, a human face at conversational distance, a notification indistinguishable from one about your own child.
Every marker the machinery uses to tell far from near has been stripped or inverted. Not through malice — through the ordinary logic of improving media. Better delivery is the problem.
Reframe the standard critique: social media's deeper harm isn't reward-hacking, it's that it destroys the distinction between the three tiers and then demands you switch between them several times a minute.
Part III — What It Costs
7. The Overloaded Switchboard
Tier A on the anatomy, Tier C on the interpretation. This is the chapter where the neuroscience lives — contained, hedged once, then used.
Default mode, task-positive, salience. Plain language, no "I"/"me" labels. State once, clearly, that these are functional networks that overlap and co-activate rather than discrete switchable modules, and that "switchboard" is a metaphor you're using knowingly. Then use it.
This chapter must resolve the contradiction, not dodge it. The reader has probably encountered "we need more reflection, less doing." But mind-wandering predicts lower momentary happiness (Killingsworth & Gilbert 2010), rumination is default-mode-linked, and the best nature study in the literature is a study of nature reducing self-referential activity (Bratman 2015). So more reflection is not the prescription.
The resolution — and the reason this book differs from its shelf-mates — is that the target is flexibility, not more of either mode. Neither "be more present" nor "reflect more." The ability to switch appropriately, which is exactly what tier collapse destroys.
8. Caring About What You Cannot Touch
Tier C — and the most under-developed idea in the project. It may be the best chapter in the book.
The distinctive modern injury isn't distraction. It's the actionability gap: intense, genuine, physiologically real concern about matters you have no capacity whatsoever to affect. Repeated daily. For years.
Local news came with something to do. Distant news, historically, came without urgency. Modern distant news arrives with the urgency and without the action — a combination that had no evolutionary precedent and no cultural handling.
Sit with what this produces: guilt, helplessness, compassion fatigue, moral exhaustion, the peculiar shame of scrolling past a catastrophe. Then be careful — the chapter must not conclude that we should stop caring about distant suffering. It should conclude that caring without a channel for action is a state we've engineered at scale and never designed for, and that the answer is building channels, not narrowing the circle of concern.
9. The Office Is Also News
Email, meetings, Slack, dashboards as mis-tiered information — everything arriving at tier one regardless of what tier it belongs to. Most "work-life balance" complaints as switching failures rather than time-allocation failures (Tier C — say so).
What a workplace that respected tiers would look like: information arriving with its tier marked, most things arriving as neighbourhood news, very little arriving as local. Absorbs the useful half of the old leadership chapters without pretending to be a management book.
Part IV — Retriage
10. The Question
The practice, and it's one question: is this within a day's walk?
Not a rule about screen time. A habit of asking, at the moment of contact, which tier a thing belongs to — and then handling it accordingly. Tier three information is not forbidden; it's re-filed. You may know about the war. You may not treat knowing as acting.
Why this beats abstention, with the evidence on your side: total digital abstinence has the weakest record in the detox literature, several studies find harm during the detox, and interventions that change how people engage outperform those that reduce exposure. Abstinence fails because it treats the problem as volume. It's structure.
11. A Relevance Diet
Concrete practice. Choosing sources by tier rather than topic. Scheduled windows for tier-three information, with a deliberate ending. Restoring the markers media stripped: reading distant news in past tense and in text, at a delay, in longer form — because form was always the filing system.
And the honest hard part: what to do with tier-three information you shouldn't drop. Distant suffering that ought to move you. The chapter's answer is to convert it into something with a tier — a donation, a letter, a vote, a commitment — or to consciously accept it as knowledge rather than as summons. Both are legitimate. Oscillating between them is what exhausts people.
12. What a Walk Is For
Tier A — end on your strongest evidence.
Bratman 2015 as the spine: ninety minutes in nature reduced rumination and subgenual prefrontal activity; ninety minutes in a city did neither. Same duration, same effort, different result. The setting did the work.
From this: 5,000 steps somewhere quiet beating 10,000 in a corridor (flag as the strong untested version of a supported finding). A natural environment as a place with almost no tier-one signals — nothing in a forest is pretending to be urgent. The restorative effect isn't mystical and isn't about exercise. It's the only environment most people still enter where the relevance machinery gets to idle.
Close with the woods, alone, talking to yourself. The image the whole theory started from, earned by now rather than asserted.
Conclusion — Attention as a Moral Faculty
Relevance-sorting isn't a productivity concern. It's how you decide who your neighbours are, what you owe, and what is yours to carry. A culture that has lost the ability to distinguish near from far hasn't just lost focus — it has lost the ability to be reliably useful to anyone.
Not a retreat from the world. A reclaimed capacity to tell which part of it is yours to act in.

Notes to self before drafting
- Start with chapter 12 or 8. Twelve is the best-evidenced and most concrete; eight is the most original and most emotionally alive. Chapter 1 is the worst possible starting point and always is.
- Chapter 3's opening paragraph is the most important in the book. It's where you say: this model is mine, nobody has tested it, here is why I think it's true anyway. Get that paragraph right and you can be believed everywhere else.
- Every claim in Part II is Tier C. Write "I think" and "my guess is" more often than feels comfortable. The book's credibility is built on the reader noticing you do this.
- If a chapter can't be justified against the spine sentence, cut it — including any of these.
