Start here

Most people who find their way here have already worked through the available options. The medical system has real tools and they are not enough. The wellness industry has too many tools and most are not serious. What these situations share is not a diagnosis. It is the recognition that the available options are not adequate to the situation.

Fieldnotes is the written record of a small psychedelic-assisted therapeutic retreat in Costa Rica that works with people in roughly that position. The writing exists because the work is unfamiliar enough, and the field around it noisy enough, that a serious person needs more than a brochure to make a real decision. These are the essays we'd want that person to read first, and the ones we'd want their physician or advisor or spouse to be able to read alongside them.

The paths below aren't the full archive, just a curated way in. None of the essays need to be read in order, and some appear under more than one path because the territory overlaps. Start where you recognize yourself.

If you're skeptical of the whole scene.

You've watched the psychedelic gold rush. Most of what's on offer is either vaguely spiritual or cynically clinical, and you're not sure which is worse. You're inclined to think a lot of this is nonsense dressed up in neuroscience vocabulary. You're mostly right, and that instinct is the correct place to start. The essays below are the ones where we say plainly what the field gets wrong, with the receipts.

Your Shaman Can't Help You — Why imported ritual fails the modern guest, and why "ancient wisdom" marketing is usually a tell.
The Guru Trap — Why Authority Becomes Dangerous in Altered States. The neurobiological case against the charismatic healer, and what should hold authority instead.
Does Your Retreat Have a Cocaine Plan? — Understanding Neuroplastic Risk. The question that separates a serious operation from a beautiful setting with good intentions.
The Leaderless Cult — When the System Becomes the Guru. How an elegant therapeutic framework can radicalize a practitioner with no charismatic leader anywhere in sight, and why that should worry you more than the obvious kind.
Is This a Blue Zone Thing? — The hardest discipline is refusing to build on stories we would most love to be true. Why we won't sell you Costa Rica's longevity halo, and what it looks like to turn the same skeptical spotlight on our own claims.
The Long March from Freud's Couch to Everyone's Inner Child — You are made of discontinued psychology.How psychological ideas lose their limits on the way into culture, and why you keep the vocabulary long after the theory dies.
Dr. Shaman — When Science Meets the Sacred. A healer with a 3,000-year track record takes his protocol to an IRB, and then to the FDA. The satire is the argument about what the field's gatekeeping does and does not actually protect.
The Unexamined Life Is Not Worth Living — Socrates, 399 BCE—brought to you by SoulCycle™. A two-minute companion to Dr. Shaman, on the point where self-awareness stops being liberating and becomes a concierge-level prison.

If you've done everything right and something's still off.

The career works. The life looks right on paper. But the thing that used to drive you now runs on fumes, and the usual fixes (a new project, time off, pushing harder) have stopped returning what they used to. This is not a character flaw, and it is not a midlife cliché. It has a mechanism, and it shows up at your altitude more often than anyone admits.

Hollowed Out — On the Hidden Cost of Abstracted Work. What happens when decades of intelligence get disconnected from anything you can touch.
The Retirement Trap — What Happened to Sergey Brin's Brain. Why stepping back from the thing that organized your mind can trigger a collapse that looks like depression but isn't.
What the Hell Happened to My Executive Function? — Why Chronic Stress Can Mimic ADHD in High-Achieving Adults. You were sharp your entire career. Now you can't focus. It may not be what your doctor thinks.
The Twenty-Year Tax — The slow drip you stopped noticing. Why a low-grade dysphoria that has lasted decades gets misfiled as personality, and what changes when you treat it as a condition instead of a trait.
The High Cost of Zero Friction — A rutted road and misplaced fury. Why an environment engineered to remove every obstacle quietly deconditions the nervous system, and why the repair is restored contact with the real rather than manufactured hardship.

When nothing you've tried has worked.

You've done the therapy. You've tried the medications, maybe several, maybe for years. You've been told it's treatment-resistant, or you've stopped expecting any label to help. The exhaustion is real and so is the suspicion that you've simply been written off. You haven't. The failure of the standard tools is often information about the problem, not a verdict on you, and that distinction is where this work begins.

You Didn't Fail Treatment. Treatment Failed You. — Two decades of treatment, aimed at the wrong layer. Why years of medication, therapy, and stimulation can leave the core untouched, and what it means that the problem lives at a level none of those tools were built to reach.
After the Flood — The experience isn't the transformation. Why the medicine surfaces the material but can't, on its own, finish the job, and what a serious plan for the aftermath requires.
Insight Is the Consolation Prize — Direct Acquaintance Is the Jackpot. Why understanding your pattern has never been enough to change it, and what does the rewiring.
The Half-Life of Insight — A breakthrough and a misplaced verdict. Why the clarity fades within weeks of getting home, why that is the most predictable event in the process rather than your personal failure, and what makes an insight survive contact with the life that produced the problem.
The Medicine Really Is Inside You — But not the way you think. Why excavating the self keeps hitting the Insight Ceiling, and why transformation depends less on digging deeper than on entering conditions that finally support reorganization.

A chapter is closing and you don't know what comes next.

A marriage, a career, a child grown and gone, a diagnosis, a death. Something that organized your life has ended or is ending, and the question isn't how to feel better about it. It's who you are on the other side of it. This is not depression to be corrected. It's a passage that most of the culture has no language for, and pretending otherwise is part of why it feels so isolating.

The Hope Trade — What the longevity industry is actually selling. The same capacity that built a remarkable life becomes the grip that makes mortality unbearable, and why that grip can loosen.
When Healing Threatens Who You Think You Are — The Achievement Paradox and the identity that won't let go. Why the machinery of high achievement builds a self so rigid that even noticing the problem gets read as weakness.
The Cruelty of Endless Time — Depression doesn't just dampen mood. It warps time itself. What grief and stalled transition do to the experience of time, and what interrupts the loop.
What's Wrong with Wanting to be Happy? — A case for better targets. Why "I just want to be happy" sounds wise after a chapter ends, and why it fails as a plan: feelings are weather, and weather is the wrong material to build a house from.
From Necessity to Design — The Nāhua Story. How this work began, on the other side of a death. The origin is not incidental to the method.

You're looking into this for someone you love.

You may be a spouse, an adult child, a family-office principal, a concierge physician, or the person tasked with vetting this before anyone commits. Your job here is not self-recognition. It's diligence. You want to know whether this is serious, whether it is safe, and what actually happens before, during, and after. The essays below are the ones to read with that lens, and you should know up front that everything on this site is written to be read alongside the person you're evaluating it for, and alongside their physician. Nothing here depends on belief.

Does Your Retreat Have a Cocaine Plan? — Understanding Neuroplastic Risk. The clearest single test of whether a program has thought seriously about safety, or hasn't.
Which Psychedelic Is Right For You? (Wrong Question) — The first question is almost never which molecule. It is the state the person is in and the container that will hold it. A clean test of whether a program reasons the way a careful evaluator does.
"There Are No Bad Trips" Is a Lie — How the gospel of surrender can make real harm harder to see. The honest accounting a serious decision requires: what a difficult experience is and is not, and the three things to watch afterward — grip, function, trajectory.
After the Flood — The experience isn't the transformation. Why the weeks and months after matter more than the dose, and what to ask any program about its aftercare.
What the No Is Protecting — "I don't do drugs" is a complete answer. It is also, sometimes, a locked door. For the reader living alongside someone's "I don't do drugs": why the no deserves to stand, why the fear beneath it may still be discussable, and the one non-directional question that honors both.
From Necessity to Design — The Nāhua Story. How the retreat is built, and why every part of the architecture is a deliberate choice rather than an aesthetic one.

The paths above are ways in. The collections below are the larger threads running through the archive.

Signal Loss Model — What has actually gone wrong?
The Signal Loss Model is the most technical body of work on this site: a ten-part sequence on treatment resistance, written for readers who want the deeper mechanism rather than the simplified version. It traces how Untethered Cognition, Neuroimmune Dysregulation, and Pursuit-Reward Decoupling can converge into a specific kind of collapse that standard psychiatric language often fails to describe. It is dense, cumulative, and best read in order. Most readers do not need to start here. But for the neurobiologically inclined, this is the deep end.

Curious Case — How does scientific knowledge actually get built?
A history-of-science series about how medicine and psychiatry came to know what they know: slowly, unevenly, and often after being confidently wrong for a very long time. Curious Case exists for readers who respect science but distrust oversimplified certainty. These essays follow the evidence, the accidents, the reversals, and the uncomfortable moments when a field has to change its mind.
