The Workshop
My father had a workshop in the back garden.
Not large — four metres by five, perhaps, with a wall of planks blackened by grease and smoke, and a shelf on which sat, in an order only he understood, keys of various sizes, rubber stoppers, screwdrivers with worn red handles, a cardboard box of screws sorted by length. It smelt of diesel, of warm metal, and of a thing I don't know how to name other than hard-won order.
That's where I watched him work whenever I had the patience to stay. Neighbours came with ailing cars, broken wheelbarrows, water pumps that would no longer start. He listened first — not to the engine, but to the man. He let the sentence finish, even when the sentence was long and imprecise and contributed nothing technical. Only after that did he put his hands on the engine.
I never heard him say he didn't know. He'd say "let's see" — and in his way of saying it, "let's see" was not a hesitation, it was a method. He said an engine will tell you itself what's wrong if you listen to it properly. That haste ruins any diagnosis. That the worst thing you can do is replace the part you suspect before checking the one next to it.
He died without knowing there were four equations that described exactly what he did.
Not in the workshop — there his intuition was precise. But in life. In decisions. In money. In health. In the choices he made without instruments, with common sense and the experience of a man who had lived in scarcity and who had learned that caution costs less than boldness.
Sometimes it costs less. Other times it doesn't.

What Was Not Taught in Botoșani in His Time
My father finished eight grades. Eight grades in 1960s Romania, with a neighbourhood school, with teachers who had shortages of their own, with textbooks more concerned with commitment to scientific socialism than with the instruments of thought.
Nothing can be held against him. He had no access to what did not exist.
But I want to be precise: it's not that his school wasn't good enough. It's that my school wasn't good enough in this regard either. And nor, for the most part, is my son's school.
There are four laws of probability — four equations discovered by mathematicians over the last three hundred years — that govern every decision made under uncertainty. Any decision about money, health, investment of time or energy, any moment when you don't know for sure what will follow and yet you must choose.
My father made such decisions his whole life. I make them. My son will make them.
None of us received the equations.
This is the article about what happened without them. Not a tragedy — my father's life was not a tragedy; it was a full life, lived with dignity and with a diligence that deserves more respect than any article can give. But it is an account of the places where the absence of an instrument leaves marks. Small marks, repeated, that accumulate.
The First Equation: Expected Value — or Why the Lottery Was Not Hope
My father didn't play the lottery obsessively. He played rarely, but he played. And when he once won something small — a few hundred lei — he talked about it for weeks as if it were an argument. "You see — it can be won."
I heard that phrase often enough to know it wasn't naïveté. It was a conclusion drawn from a real experience. He had won. Therefore it can be won. Logical.
What was missing from the reasoning is the thing mathematicians call expected value — which is calculated by multiplying each possible outcome by its probability and adding it all up. It's an equation that fits on a quarter-sheet of paper and which, once understood, completely changes how you look at any bet, any promise, any offer.
The expected value of a lottery ticket is negative. Not mildly negative — radically negative. The national lottery returns to players, on average, less than half of what it collects. That means for every leu you put in, you come back on average with less than fifty bani. Repeated weekly, monthly, yearly — it's a voluntary tax on hope.
My father's winnings were real. But the winnings of one real person in a system with negative expected value don't prove the system is good. They prove that he was the one who caught the random upside of a negative distribution. The others — far more numerous — caught the downside. They didn't talk about it.
That's the first mistake the absence of the equation produces: confusing a result with proof of a system. I won doesn't mean it's worth playing. It worked doesn't mean it was a good decision. Sometimes bad decisions produce good outcomes. Sometimes good decisions produce bad outcomes. The equation helps you distinguish the quality of the decision from the quality of the outcome — which is the only judgement that matters if you want to do better next time.
My father didn't know this. It's not his fault. But he paid for it in dozens of small decisions where enthusiasm or fear guided him instead of calculation.
And I paid with him — in the years of childhood when the family's resources were allocated by feel, not by calculation. Not out of malice. Out of the absence of an instrument.
The Second Equation: The Base Rate — or Why the Medical Test Said One Thing and Meant Another
This is the section I wrote and deleted three times.
Not because I don't know what happened. But because I know too well, and the distance between knowing and being able to write is sometimes vast.
My father reached hospital with some vague symptoms — fatigue, a pain that wouldn't settle anywhere, a malaise without a clear name. The doctor at the county hospital recommended a test. The test came back positive. The doctor said the test was ninety-five per cent accurate. The family understood that my father almost certainly had what the test indicated.
They mobilised. Further investigations in Cluj, because the county didn't have the equipment. A long journey, large costs for a family with modest resources. Stress distributed equally among everyone around, including me, who was a student at the time and couldn't understand why my father looked worse after we found out "what he had" than before.
The investigations in Cluj showed he didn't have it. The test had returned a false positive.
The county doctor hadn't made a mistake. The test was genuinely accurate. The problem was something else, and no one in that room — not us, not the doctor, not the nurse — asked the right question: how many people with his profile — age, area, risk factors — test positive on this test without being ill?
The answer, which I looked for much later, was: many. The disease the test was looking for was rare in the general population of men his age and profile. And the test, however accurate, produces false positives in a fraction of healthy people tested. When the disease is rare and the tested population is large, false positives often outnumber true positives numerically.
This describes an equation published in 1763 by an English clergyman named Thomas Bayes, posthumously, by a friend who thought it worth printing. Its fundamental conclusion: evidence doesn't tell you the truth. It updates the probability you had before. If the starting probability is low — if the disease is rare — even strong evidence can leave the final probability low.
My father didn't die because of that test. He died later, of something else, with no direct connection. But I carried that journey to Cluj for a long time as an unnecessary burden — money we didn't have, weeks of white fear, physical effort from a man who was already tired and who had to make a long journey to find out he was healthy of what we thought he wasn't.
If someone in that hospital room had known Bayes' equation — or at least the simple question it contains — we would probably have asked a different question before buying the train tickets.
I don't know how it would have ended otherwise. Perhaps the same. But I paid the price of ignorance in its most concrete form: in money and in hours and in fear of something that wasn't there.
The Third Equation: Variance and the Risk of Ruin — or Why a Loss and a Gain Never Cancel Out
My father had a period, in the mid-1990s, when he believed in transformation.
It was a time when everyone believed in something — in transition, in the free market, in the possibility of escaping a long poverty through one decisive move. He invested — if it can be called that — the family's savings with a friend who "knew" a business. Not much. For us, then, it was a lot.
He didn't gain anything. He lost everything he'd put in. The friend didn't disappear in a dramatic sense, but in the sense that he went about his own business and never brought it up again.
My father carried on. He didn't complain much. He worked harder to recover. He recovered partially, over time. But something changed — not in him as a person, but in his disposition toward risk. He became more cautious than was natural. Too cautious, perhaps, because the loss hadn't been only financial; it had also been a blow to his judgement of himself.
There is a law of probability that explains why recovery is structurally harder than loss. It's called, technically, the property of non-ergodicity — but translated simply: a fifty per cent loss is not compensated by a fifty per cent gain. If you have a hundred lei and lose half, you have fifty. To get back to a hundred, you need a gain of one hundred per cent of what remains, not fifty. Losses and gains are not symmetrical. Ever.
This means that any strategy which allows the possibility of reaching zero has, over the long term, a value of zero — regardless of how good the calculation looked before that moment. Zero is absorbing. Zero is not recovered from; it is rebuilt from nothing, which is a completely different and much longer road.
My father didn't know this. He put too much on a single bet, without a safety net, without a reserve to keep him in the game if it went wrong. It went wrong. It didn't destroy him — he was a strong man, with reserves of resilience he'd built over years of scarcity. But it took him out of the game for a few years. It cost him energy he could have used otherwise.
And it cost me too: there were years of childhood when austerity was not a chosen lifestyle but a consequence of a lost bet. We didn't have it bad. But I carry with me the knowledge that fragility is not a moral state — it's a structural one. That a single point of failure, in the absence of reserve, can change a person's trajectory for years.
The irony I understand only now: it's precisely this law that explains why insurance is rational, even though from the perspective of expected value it's a bad deal. You pay more than it's statistically worth, but you buy the absence of the path that can bring you to zero. My father couldn't afford insurance on the things that truly mattered — not through negligence, but through lack of resources. But if he had known that the logic behind insurance was the same logic that explained why he'd lost, perhaps he would have thought differently about some decisions.
The Fourth Equation: The Kelly Criterion — or How Much to Bet When You're Right
This is the equation I find most painful in its absence from the education of a man who works with his hands and with his own judgement.
A physicist named John Kelly formulated it in 1956 at Bell Labs, solving a completely different problem — noise on telephone lines. His conclusion, applied to decisions: there is an optimal fraction of your resources to put on any bet. Not all of it. Not as much as you feel it deserves. A calculable fraction, which grows with your advantage, but which is never all of it.
If you put less than the optimal fraction, you gain more slowly than you could. If you put exactly the optimal fraction, you grow as fast as possible over the long term. If you put more — even with a real advantage, even when you're right — your gains decline. Double the optimal stake brings zero gain. Triple it and you're in systematic loss.
Let me repeat, because it's counterintuitive: you can lose money systematically while being right most of the time. Not because the analysis is poor. But because the stake is too large.
My father put everything or nothing. That was his philosophy of life — and in the workshop it was perfect. When he opened an engine, he gave everything he had: concentration, patience, experience. There was no half-attention in a repair.
But in decisions under uncertainty — money, people, placement of resources — the principle of all or nothing is a formula for amplifying both gains and losses. My father gained much from decisions made with everything he had and lost much from the same decisions. His life's trajectory would have been more stable — not less effortful or less courageous, but more stable — if he had known there was an optimal proportion and that exceeding it doesn't mean more courage, but more fragility.
I don't judge him. The philosophy of total commitment is dignified and often admirable. But it belongs to the domain of morality, not of decision under uncertainty. Morally, it's worth giving everything. Mathematically, if you give everything on an uncertain bet, you increase the probability of reaching zero.
What I Paid
This article isn't about my father as a victim of not knowing. He wasn't a victim — he was a man who made decisions with what he knew and lived with their consequences with a dignity that makes me respect him more than the respect being his son would impose on me anyway.
It's about me.
I grew up in an environment where decisions were made by feel, by accumulated experience, by the advice of elders. Where a question like "what's the expected value of this choice?" would have produced no recognisable answer — not because it would have been a bad question, but because the language in which it was posed didn't exist in the available lexicon.
And I inherited the model. I inherited it not consciously, not deliberately, but in the way you inherit someone's walk after watching them for years — without realising you've taken on both the gait and the style of deciding.
I put too much on sure bets. I ignored the base rate when it suited me to ignore it — when a client seemed certain, when a project seemed guaranteed, when a decision seemed clear without calculating how many such clear decisions had proved wrong in the past. I confused, on multiple occasions, a good outcome with proof that the decision had been good — and I repeated similar decisions based on that confusion.
I didn't go bankrupt. I didn't lose catastrophically. But I have a list — which I won't make public in its entirety — of moments where a ten-minute calculation would have given a better answer than what I did.
And I have a question that haunts me: if my father had known the equations, if I had known them at twenty — what would have been different? Not everything. Perhaps nothing fundamental. But a few crucial choices, yes. A few moments where I put too much or too little, where I misread evidence, where I ignored that there was a path that could end the game.
The price isn't dramatic. It's diffuse. Distributed across years, across small decisions, across resources squandered not from ill will but from the absence of a framework. It's the price anyone pays who lives without these instruments — and it's paid so naturally, so continuously, that you don't even feel it as a price. You feel it as life.
About My Son and the Equations I Give Him
I have a seventeen-year-old son.
We live in the same house and sometimes at the distance of a universe — me with my screen, him with his headphones, each in his room in the same house on the same street in the same Botoșani where I grew up too. I've accepted that I can't give him everything I wish for him and that, of what I can give, an important part is invisible and will become visible only later.
I give him the equations.
Not as a maths lesson. Not as a wise father's speech. As an instrument I didn't receive in time and which I pass on not because it makes me look clever, but because its absence costs — and I've paid enough to know the price.
I wrote him a longer letter — episode 74 of the series on servicii-web-alex.com — in which I explained the four questions through examples from his life. This letter is something else. This letter is about why it matters to pass them on.
My father couldn't give them to me. Not because he didn't wish to give me everything that was best — he did wish it, and in many respects he delivered. But because he didn't know them. There was no one in his chain who had known them and passed them on.
I know them now. Late, partially, with the errors attendant on my own imperfect application. But I know them.
And this is the thing my father's death clarified in me more than anything else: that the transmission of instruments of thought is a form of respect toward those who didn't have them. Not a form of superiority over them. Not a declaration that I know better. But a continuation of an effort they made with what they had and which I can make with more.
My father would have wanted this. I know he would have — in the way a man who built with his hands his whole life understands that better tools don't diminish the one who worked with more primitive instruments. They honour him.
The Price of Ignorance Is Not Moral. It's Structural.
I want to be explicit about something this article might suggest incorrectly.
I'm not saying my father was morally wrong in his decisions. I'm not saying people who don't know these equations are less intelligent or less dignified. I'm not saying those who know them live better lives in a human sense — happier, fuller, more valuable.
I'm saying that in the specific domain of decisions made under uncertainty, the absence of a framework produces systematic errors. Errors that aren't accidents — they're predictable consequences of the absence of an instrument. And these errors are paid for in concrete resources: money, time, energy, years.
The price of ignorance isn't a moral punishment. It's a structural consequence, just as a person who works their whole life without ergonomic tools will end up with back problems — not because they're bad or negligent, but because the body has laws that don't forgive the absence of the right instrument, regardless of good intentions.
The education system could reduce this price. Not through more mathematics in the abstract sense — but through teaching probability as an instrument of thought applied to real life. Through exercises with real decisions, not with imaginary urns. Through discussions about the expected value of concrete choices, not about combinations and permutations without context.
It's not an academic critique. It's an observation about what's missing and what it costs.
The Ending I Didn't Plan
This article started from my father and from his workshop.
Finishing it, I notice it has arrived, once again, there. Not as planned symmetry, but as a natural consequence of the fact that everything I know about well-made decisions I first saw there — in the way he listened to an engine before putting his hands on it, in the patience with which he let the diagnosis come from the part, not from assumption.
He didn't know the equations. But he knew to listen before acting. He knew that haste ruins the diagnosis. He knew that the suspected part isn't necessarily the guilty one. He knew that an engine repaired wrongly costs more than one that hasn't been touched.
All these are, in informal language, versions of the same four principles.
No one taught him. He discovered them alone, over years of work, through trial and error and through that kind of practical intelligence that no formula produces, but which a formula can articulate and accelerate.
The equations belong to him. I found them in books. He built them in the workshop.
The difference is that I can pass them on in a form that doesn't require a workshop and thirty years of experience. That difference matters. It honours him, I believe.
The workshop was demolished years ago. Another owner took it. It smells of something else now.
But the keys sit somewhere in my memory — sorted in the order only he understood — and sometimes, when I set about something with my hands, his instinct comes to me: listen before acting, let the part speak, don't replace what you suspect before checking what's next to it.
That's the best instrument he passed on to me.
The other four I found myself. And I pass them on.
Ten Questions to Retain — and Eloquent Answers
A section for the reader who wants to go deeper than the text.
Question 1. The article says my father "paid" for not knowing the equations. But he lived well, with dignity. Isn't that an unfair judgement of him?
This tension is real and I felt it while writing. The answer is in the distinction from chapter IX: the price of ignorance isn't moral, it's structural. The price doesn't diminish dignity — it coexists with it. A man who works his whole life with a less ergonomic tool than he might have isn't less dignified than one with the right tool. He has back problems the other doesn't have. Both things are true at the same time. About my father: he was an admirable man who paid the predictable consequences of the absence of instruments he didn't receive and couldn't seek out. Admirable and structurally vulnerable. That's not a contradiction.
Question 2. Expected value is an economic concept. How do you apply it to emotional decisions — relationships, friendships, life choices?
With caution and with recognition of its limits. Expected value works well for repeatable decisions — where you can play enough times for the statistical distribution to manifest. It works less well for unique and deeply personal decisions, where the variables aren't quantifiable and where what you lose or gain can't be expressed numerically. Relationships aren't bets with calculable EV. But even there, the underlying question remains useful in humanised form: what am I investing, relative to what I receive, on average, if I look at the long trajectory of this relationship? Not as a balance sheet, but as an exercise in honesty with oneself.
Question 3. The false-positive medical test is a dramatic example. In ordinary life, where else does the base-rate error appear?
Everywhere we take isolated evidence as a conclusion. We buy a product because a friend had a good experience with it — without asking how many of their acquaintances had bad experiences and didn't recount them. We hire a collaborator because the first impression is excellent — without asking what the base rate of misleading first impressions is in the field. We believe a viral news story because it was shared by someone we trust — without asking how many false stories circulate at the same time through the same channel. The evidence doesn't disappear. Its weight changes radically when you place it in the complete field from which it comes.
Question 4. Does the principle "zero is absorbing" apply in the emotional or professional sphere too, not just the financial?
Yes, and it's perhaps the most important generalisation. A person who reaches complete exhaustion — total burnout, not ordinary tiredness — doesn't recover through rest proportional to the exhaustion. They recover harder and more slowly than seems mathematically natural, for the same structural reason: a loss of fifty per cent requires a gain of one hundred per cent of what remains. A professional reputation destroyed by a single public incident costs years of reconstruction, not months proportional to the size of the incident. A definitively broken friendship isn't restored through half the effort with which it was built. Zero — or near zero — has a special property that makes recovery qualitatively different from any other loss.
Question 5. The Kelly criterion assumes you know how large your advantage is. But often you don't. What do you do?
You apply a practical rule that professionals use: bet significantly below Kelly, not at Kelly. If you estimate you have a thirty per cent advantage, bet as though you have one of fifteen. The reason is that human estimates of their own advantage are systematically overestimated — studies show that in almost any domain, people believe they're better calibrated than they are. By betting below Kelly, you forgo a percentage of theoretical maximum gain, but the real gain is in survival: overestimating and staking at real Kelly leads to bankruptcy; overestimating and staking at half-Kelly leads to a slower rate of gain. Slower is infinitely better than zero.
Question 6. The article talks about a father from his generation. Does the current generation, with access to the internet and information, still have the same gaps?
They have different gaps and some identical ones. The identical gap: probability isn't taught as an instrument of thought applied to real life, not even today. The different gap: the overabundance of information produces an illusion of calibration — the impression that because you have access to everything, you know enough. Often, access to information without a framework for interpretation produces more confusion than the absence of information. A person who doesn't know a medical test can produce a false positive is vulnerable. A person who has read on the internet that medical tests always produce false positives and has decided to stop having tests is equally vulnerable, in the opposite direction. The framework — not raw information — is what's missing.
Question 7. You wrote that you inherited your father's "model" of deciding without realising it. How do you recognise an unconsciously inherited pattern?
Through repeated consequences, not through direct introspection. If the same category of mistake repeats in different circumstances — I always put too much on a single bet, I always ignore warning signs from a certain type of situation, I always react disproportionately to a certain type of loss — the pattern is there, whether I see it or not. Introspection alone doesn't easily uncover it, because the rationalisations we construct are exactly the size of the pattern. What helps: someone from outside who has watched long enough, a decision journal reviewed in the cold light of a few months later, and the honesty not to call bad luck what is in fact repetition.
Question 8. The letter seems to suggest that transmitting instruments is a duty toward those who didn't have them. Isn't that too much? Isn't it enough to live well yourself?
It isn't too much, and it isn't enough. The argument for transmission isn't abstract altruism — it's the recognition that instruments of thought aren't private property; they're cultural inheritance to which you have access through the luck of birth, era, or educational access. My father didn't have them not because he was less capable — but because they didn't exist in his space. I have them not because I'm more capable — but because I lived later and read more. Transmission is the recognition that access was asymmetric and that the asymmetry is reduced through transmission, not through keeping.
Question 9. The article is personal-confessional. Doesn't it risk seeming self-indulgent — a father analysing himself and his own to write an article?
The risk exists and I felt it while writing. The answer I gave myself: self-indulgence appears when confession serves the author's image, not the reader's understanding. The test is simple: if the reader finishes the article thinking about the author, it's self-indulgent. If they're thinking about their own father, about themselves, about a decision they made without instruments — the confession has fulfilled its function. I can't control how each person reads. I can control that I haven't ornamented the mistakes, that I haven't turned them into narrative virtues, and that I haven't artificially resolved the tensions.
Question 10. In the end, the workshop disappears physically but remains in memory. Is that a rhetorical or biographical choice?
Both. The workshop really did disappear — another owner, another function. And the memory of the instruments — the way I instinctively finger the keys, the way I listen before intervening — really does persist. That these two biographical facts also served a rhetorical function is something I declare without embarrassment: good rhetoric doesn't invent, it selects. From the available biographical material, I chose what could bear the weight of the idea. If the selection is transparent to the reader, it isn't manipulation — it's craft.
Author's Note — How This Article Grew
From a discussion about luck to the concrete price of ignorance
This article wasn't planned as an article.
The plan was simpler: an extension of the series of epistles from /fiul, transposed into the personal register of cojocarupetru.info. The same subject — the four equations of probability — but with the voice changed. There I wrote as a father who transmits. Here I wrote as a son who received less than he would have wished.
What I hadn't anticipated is that the shift to the confessional register changes more than the voice. It changes the stakes.
When I was writing episode 74, I knew what I wanted to transmit and I built toward that. The structure was clear from the start: four questions, four chapters, personal anchoring at the end. I was writing with pedagogical intent, even if the intent was dressed in a letter.
When I started the present article, I didn't know where it ended. I knew I was starting from the workshop — the concrete place that functioned as the space of my father's thinking — and that I wanted to arrive at the equations. But between the two lay a territory I hadn't mapped: what exactly, in his life and mine, could be connected to the absence of the instruments? Not metaphorically, but concretely?
The answer came through three biographical moments that imposed themselves: the lottery with its small win turned into an argument, the false-positive medical test and the journey to Cluj, the lost investment from the nineties. I didn't choose them rationally. They appeared in the order that corresponded to the four equations, and I understood later that my mind had already arranged them.
The tensions of writing:
The first and most difficult: how do you write about the mistakes of a dead man without judging him and without idealising him? Both ends of the spectrum are available and both are false. My father was neither an innocent victim of a system, nor a hero without faults. He was a man who made decisions with what he knew. The article had to stand in this middle zone, which is also the most uncomfortable, because it gives the satisfaction of no simple narrative.
The second tension: distance from the biographical material. The medical test is an episode that hurts me still today — not because it produced serious consequences, but because it produced unnecessary fear, because it cost resources we didn't have, and because no one in that room knew how to ask the right question. Writing this, I oscillated between analytical distance and the emotional closeness that makes the text breathe. I chose to allow both — to name explicitly that I deleted and rewrote the section three times — because this confession is more honest than a text that seems to have flowed smoothly.
The third tension: the personal stakes of chapter VII. I wrote that I inherited my father's model of deciding and that I paid for it. That's true. But it's also a statement that exposes me — it declares not my dignity, but my limits. In the register of cojocarupetru.info, this exposure is part of the contract with the reader. Elsewhere it would be inappropriate. And yet, even there, I felt the resistance of giving too much without seeing clearly what the reader gains from what I give.
The subjective mistakes I've assumed:
I chose not to reveal all the details of the lost investment from the nineties. It's a decision that protects the concrete memory of people who are still alive, but it leaves a gap in the text — the reader knows there are details they're not receiving. I chose to declare this restraint explicitly ("I have a list I won't make public in its entirety") rather than simulate completeness. Declaring the gap is more honest than silently omitting it.
I chose to link the article to episode 74 through endnotes, not through references in the body. This lets the text breathe independently, but may create the impression that there are two parallel texts without dialogue. The trade-off is conscious: the internal coherence of each text matters more than the visibility of the link between them.
Potentially mistaken perspectives I anticipated:
"The article is an implicit critique of the Romanian healthcare system." Yes and no. The county doctor didn't make a mistake — he correctly applied an accurate test. No one in that room knew how to ask the question about the base rate, including me, who was a general medical student at the time and should have known. If it's a critique, it's one about the absence of probabilistic education from all domains, not about the quality of the specific medical act.
"The article romanticises poverty and the lack of instruments as a form of authentic dignity." I tried to avoid this — explicitly, in chapter IX. But I know the elegiac tone around the workshop can be read in that direction. The workshop isn't romantic because it was poor. It's potent because it's the place where a man exercised best what he knew. The distinction matters.
The Lizards in the Text — Declared Aesopic Language
In keeping with the editorial tradition I've adopted: ideas I can't say directly I dress as something else. I declare them in an author's note for honesty toward the reader.
Lizard 1 — The Workshop as Institution
My father's workshop is real. But in the text it also functions as a metaphor for any institution that operates with old instruments in the face of new problems.
The school in Romania, as an institution, is a workshop with tools that worked well for a previous generation and that survive through inertia, not through efficiency. The teachers are, often, good mechanics with tools that no longer correspond to the problem being repaired. It's not their fault — it's the fault that no one updated the arsenal.
The workshop in the text is small and personal. The institution it alludes to is large and public. If you read only the workshop, you read partially.
Lizard 2 — The Hospital Room and the Question That Was Never Asked
The scene of the false-positive medical test spoke about a specific moment. But the structure of the scene — an authority with a precise number that produces certainty, and a family that accepts the certainty without asking the question about the field in which the number exists — repeats in dozens of contexts.
Public statistical authorities frequently produce precise numbers without base-rate context. "The unemployment rate has fallen by X per cent" — against what basis of calculation? With what definition of unemployment? "Investment in infrastructure has grown by Y per cent" — against what initial level? "Crime has fallen" — by what reporting methodology?
The hospital room in the text is any space where an authoritative figure is accepted without the question: how many are there, at origin, in the group from which this figure comes?
Lizard 3 — "The Friend Who Knew a Business"
This is the most discreet character in the article. He appears in a single paragraph and disappears. I gave him no name, no moral characterisation. He disappears "in the sense that he went about his own business".
The concrete person is real and deliberately anonymised — it's not the article's purpose.
But the typology is universal: the man who knows a business and through whom others lose their savings in periods of economic transition is a recurring figure in the history of all societies that rapidly move from one economic system to another. Romania of the nineties produced this figure industrially. Not from systematic ill will, but from the simultaneous absence of three things: a functional legal framework, basic financial education, and public critique of business models that live off information asymmetry.
The friend who knew a business isn't an individual problem. He's a structural symptom of an environment in which the expected value of the scam is positive for the scammer and negative for the victim, and no one has the instruments to calculate that before signing.
Rhetorical Tools Used in the Text
Transparency toward the reader — the mechanisms of persuasion I used and why.
The workshop as open symbol — The description of the workshop in the first chapter is intentionally dense with sensory detail: smell, colours, material order. The function is twofold. First: to anchor the reader in a precise physical space before entering abstraction — the body accepts ideas more easily when it has first been in a place. Second: to build a symbol that can carry multiple meanings — the workshop as a place of practical thinking, the workshop as a space of transmission, the workshop as that which disappears physically and persists in memory.
Deliberate restraint as an instrument of credibility — I declared in chapter VII that I have a list of personal mistakes I won't make public. This declared restraint produces more credibility than the list would have — because it signals that there's material that doesn't serve the text and that I excluded it consciously, not that I lacked it. The rhetorical paradox: by confessing that I'm hiding something, I gain more trust than if I pretended to give everything.
The first-person plural voice where I avoid the singular — There are a few moments in the text where I write "we didn't know" or "no one knew" instead of "my father didn't know". It's not a manoeuvre to avoid responsibility — it's a distribution of vulnerability that includes the reader. We didn't know. That transforms a private confession into a recognisable collective situation.
Chapter IX as internal counter-argument — Placing a chapter that anticipates and answers the main objection ("I'm not making a moral judgement") before the objection arises in the reader's mind is a classic technique for disarming resistance. The reader who would have wanted to object finds the objection already addressed — and either accepts it or is forced to formulate a more nuanced version. Both variants are more productive than the primary objection left unaddressed.
Structure in chapters with descriptive titles — Unlike the /fiul series, where chapter titles are direct questions, here the titles are nominal phrases containing the section's internal tension ("or why the lottery was not hope", "or how much to bet when you're right"). The title formulated as a diagnosis suits the analytical-confessional register better than the question-title, which invites interactivity.
The open ending, not the conclusive one — The article doesn't end with a moralising conclusion or a promise. It ends with a concrete image — the keys in memory, the inherited instinct — and with a short phrase that doesn't resolve the tension but leaves it open with dignity: "The other four I found myself. And I pass them on." The open ending invites continuation, not the satisfaction of closure.
Call to Action
What You Can Do Tomorrow — 5 Concrete Suggestions
1. Write Down an Inherited Decision — and Ask Whether It's Yours
Think of a way in which you routinely make decisions — about money, about relationships, about risk. Now ask: where does this way come from? Did you choose it deliberately or inherit it? Not as an exercise in blaming parents — but as an exercise in mapping. What in your way of deciding is an inherited pattern and what is a conscious choice? You don't have to change anything. You have to know what's what.
2. Find an Episode in Your Life Where You Confused a Good Outcome with Proof of a Good Decision
Not a failure — a success. When something went well and you concluded you'd done the right thing — without checking whether it could have gone well even if you'd done otherwise. We think reflexively about failures. We rarely analyse successes with the same rigour. Success convinces us we knew what we did. Sometimes we did. Sometimes we were lucky and confused luck with method.
3. Identify a Person in Your Life Who Makes Good Decisions — and Ask Them How They Think, Not What They Chose
Not what decision they made — how they arrived at it. What information they sought. What they deliberately ignored. What questions they couldn't answer and how they proceeded with the absence of an answer. People who make good decisions rarely have an articulated system — but they have habits of thinking you can extract through a well-placed conversation. An hour with such a person is worth more than a course on decision-making.
4. Calculate the "Price of Ignorance" of a Single Repeated Habit from the Last Three Years
Not necessarily financial. It could be a habit of time, of attention, of energy. Choose something you've repeated weekly or monthly over the last three years — an unused subscription, an activity that produced nothing, a relationship in which you invested without reciprocity. Multiply the unit cost by the frequency and by three years. Not for guilt — for clarity. The price of ignorance doesn't show at the level of a single episode. It shows at the level of accumulated pattern.
5. Pass Something Concrete On to Someone Younger Than You
Not a general piece of advice. A specific instrument: a question to ask before a category of decisions, a mistake you made and understood, a resource you wish you'd had at their age. Transmission doesn't require authority or certainty. It requires honesty about your own experience and the desire that the person in front of you leaves with something more than they came with.
What to Avoid — 7 Things Not to Do
1. Don't Turn Others' Not-Knowing into Superiority
The most common side effect of understanding these instruments: the impression that you see those who don't know them making mistakes — on the news, at the office, in the family. The impression is true and entirely useless if it produces contempt. My father didn't know the equations. That didn't make him less intelligent than me. It made him less equipped for a specific type of problem. The distinction matters enormously in how you relate to the people around you.
2. Don't Use Biographical Analysis of Others Without Their Consent
I wrote about my father. I wrote about a medical episode. I wrote about a financial loss. My father can no longer consent. I chose carefully what to include and what to leave out. If you apply the thinking from this article to the lives of people around you — parents, friends, partners — you have the duty to do it with the same care. Analysing someone's decision patterns without also offering them the instruments is a form of asymmetric power. Do it with humility or don't do it.
3. Don't Look Back Retrospectively at Past Decisions Only for Mistakes
Retrospective analysis with instruments you didn't have at the time of the decision is an exercise in pointless torture. The instruments serve future decisions, not retroactive judgement. You can analyse past decisions to understand patterns — that's useful. You can't analyse them to condemn what you chose without knowing what you know today — that's sterile.
4. Don't Reduce Your Father's Life to the Sum of Equations He Didn't Know
If you have a father who made decisions without these instruments and the relationship with him is complicated, this text can be read as a validation of pre-existing resentments. That's not the intention and it doesn't help. People are more than the instruments they have or don't have. Bad decisions don't define a person. They define the absence of a framework, and the absence of a framework is a problem of equipment, not of character.
5. Don't Confuse Transmitting Instruments with Resolving the Relationship
If you pass the equations on to someone with whom you have a complicated relationship — son, daughter, friend — that doesn't resolve the relationship. The instruments are useful independently of the relationship. The relationship has its own separate dynamics. Don't use the transmission of knowledge as a substitute for the conversation you're avoiding.
6. Don't Treat Uncertainty as a Problem to Be Solved
Probabilistic instruments don't eliminate uncertainty. They manage it better. If you use them in pursuit of absolute certainty — if you apply them until you're "sure" — you've misunderstood. The goal is to be better calibrated in the face of the uncertainty that remains, not to eliminate it.
7. Don't Delay Transmission in the Expectation of the Right Moment
My father died. I could no longer give him the instruments and watch him use them. I don't know whether he would have used them or whether they would have interested him. I have no way of knowing. What I know is that I have no solid reason to wait for a better moment than the present one to transmit what I know to the people around me. The perfect moment doesn't come. The available moment comes, and if you let it pass, you have to live with that.
