This is still early days for this. I’m in the middle of editing, I’m trying out a new way of writing essays with AI rather than doing it all solo, or all AI. There’s a LOT to do here, but we’re getting there.


We are busy in order to have leisure. — Aristotle, Nicomachean Ethics

A scenario:

A senior person is handed a difficult idea. They read the first page, skim the rest, and conclude that the thinking is muddled and the writing unclear, so its author should go away and make it clearer and simpler.

Sometimes that is the case, but often what is missing is not clarity in the document but attention in the reader, who has none to spare. One encounter cannot tell you which failed, the idea or the attention, but, over time, a distribution can. An idea that draws the same objection from many readers is probably the idea’s fault; one that only some readers cannot take might well be down to the reader. The manner of the pushback is telling too: a reader with attention to spare, who thinks the idea needs work, will say where and how; the depleted reader has just enough left to ask for it to be shorter.

Let’s call it manufactured incompetence, at least until a better phrase turns up. A capable person, in a role that exists for the exercise of judgement, is made unable to exercise it by the demands of the role. They then interpret that inability as a fault in the author of the idea rather than a condition of their own working life and the social structure that creates it. The environment rewards the appearance of seriousness, the full day and the fast reply, over the slower thing that seriousness is meant to protect.

It is tempting to reach for the Peter Principle1, which describes a ceiling: you rise until you reach a job you cannot do, and there you stall. That doesn’t quite fit, I am describing a person of ample ability, in conditions that stop that ability from being expressed. If given a free week and a hard problem, that person would be formidable. The scarce resource is uninterrupted attention, not talent, and we have drifted into an arrangement in which the most senior people are the least able to access that resource.

The world is full of difficult issues, and there’s an important role for specialists in clarifying information to provide to decision makers. However there are a lot of complex issues in the world that genuinely do require deep engagement to work out a good response. The popularity of the you can fix climate change if you just plant 1 trillion trees2 paper is a good example of this. The science since has pointed out that it’s much more nuanced, and that merely planting a lot of trees can be quite a bad idea in some situations, but there is a huge appeal of a simple answer.

“everything should be as simple as it can be but not simpler” Einstein3

How it is built

The people this happens to were, as a rule, excellent at something else first. They were promoted for being good at that, into a discipline nobody taught them. The Chartered Management Institute (2023) found that 82% of people entering management had received no formal management or leadership training, and 26% of senior managers and leaders had received none either.4 They label these as “accidental managers”. Most organisations run a single ladder: to pay someone more, or to keep them, you make them a manager, whether or not managing is something they can do or want to do.

The result is a stranding; the craft that earned the promotion moves on without them, practised now by people who still have the hours on the tools to keep up, while the craft they have now been handed was never taught to them and cannot be learned in the gaps between meetings. They sit between two competences, fluent in neither. I suspect that, in the current work climate, even if they were trained explicitly, there wouldn’t be any mention of how to engage with complex issues that can’t be thought through in a 10 slide deck.

Why the anxiety comes out as busyness

The pressure to look busy is, for most people, not vanity. It is imposed externally: a calendar filled by other people, a manager who reads a quiet hour as spare capacity, a working culture in which “you’re not paid to think” can still be said with a straight face. Performance of busyness is real, but it is the smaller part. The larger part is imposed, and the imposition rests on an old assumption, that thinking is not work, that the real work is production, and that an hour not visibly producing is an hour going spare. Newport (2024) calls this pseudo-productivity: because the output of knowledge work is hard to measure, visible activity stands in for it, as the thing that can be seen.5

There is a long genealogy to why we treat visible labour as virtue. Weber (1905/2001) traced the modern version to Calvinism and the doctrine of election, the belief that God has already chosen who will be saved and that no human act can move the verdict6. The uncertainty this produced was unbearable, so believers searched their lives for signs that they were among the elect, and steady worldly diligence became, not the cause of salvation but its evidence. Idleness, by the same logic, was damning. “Waste of time,” Weber wrote, “is the first and in principle the deadliest of sins.” The theology ebbed away and the reflex stayed. We still treat the empty hour as guilty until it proves itself productive.

Once work carries moral weight, busyness can be shown off. Bellezza, Paharia and Keinan (2017) documented the modern convention: the overbooked, never-off professional is read as important, on the inference that a person genuinely in demand would have no time to spare7. Veblen had described the opposite convention a century earlier, when the wealthy signalled rank by conspicuous abstention from work, his leisure class being people who did not have to earn a living at all (Veblen, 1899). As the leisure class has essentially disappeared, the professional, who does have to earn, now advertises worth through the full calendar rather than the empty one.

Traditionally the bottleneck has been caused by production. All the writing and coding and cutting and pasting has taken up weeks of effort, so for most people there’s been plenty of interstitial time for thinking about what they’re doing. As AI tools are more integrated into our work, the production is becoming a more trivial part of the process, the opportunities for thought are being squeezed. I once had a job where I drilled holes all day, and I did a lot of thinking while I was doing that. But now I am often working on two or more codebases at the same time in parallel AI chat sessions, my opportunities for accidental abstract thinking have been reduced almost to zero, and if I want to retain the benefits of that, I need to make those thinking opportunities an explicit part of my life.

The traditional assumption is that production is the expensive part, and thinking happens incidentally. As the making is handed to machines, the logic inverts. Deciding what is worth making and judging whether the made thing is any good, is the work that remains, and both are kinds of thinking. We are automating production at speed while still running an attention economy built for a world in which production was the bottleneck. Herbert Simon (1971) noted that a wealth of information creates a poverty of attention8. Attention is finite, it is the input the senior role actually runs on, and the busyness regime spends it on being seen to spend it. [these last two paras need to be fixed up, I added the first, and haven’t fully resolved it with the second]

The two tiers separate here. For most people the constraint is external: the time is not theirs to protect, and the demand to look occupied comes down the hierarchy. At the top it turns inward, though rarely on purpose. A senior leader could clear the calendar and think. What stops them is not a manager enforcing it but an audience they cannot ignore, a board, a market, a set of peers who read reserved capacity as underuse or as risk. To take the unhurried time the work needs, they would first have to win an argument with people who have no vocabulary for legible thinking. They do not lose that argument. They never have it, because it does not occur to them that it is theirs to start.

The maker who forgot they were a maker

Graham (2009) drew the useful distinction between the maker’s schedule and the manager’s9. Makers needs long unbroken stretches; a single meeting dropped in after lunch splits the day into two pieces too small to build anything in. Managers live in interchangeable hourly boxes and cannot see the problem. Graham’s own fix was to bolt his meetings to the end of the day and keep the mornings whole.

< roughly edited as far as here >

At least in the world I interact with, there are very few pure managers, the layers of management that were there purely for upward information-distillation seem to be gone. Graham sorts people into makers and managers, but realistically they’re more opposing mindsets than distinct groups.10 Everyone makes things, everyone who devises “courses of action aimed at changing existing situations into preferred ones” (Simon, 1969) is designing. It might be worth thinking about leaders as makers of choices. The mind behind a material artifact is doing the same processes that the mind behind a sales plan or a social policy is doing. A strategy document, a contract, a restructure strategy, a fee model, a decision about who sits next to whom: all of these are designed, and designing them well is challenging. The more useful cut runs not between maker-people and manager-people but between two modes the same person moves through. There is maker-mode, in which a thing is held long enough to be shaped, and manager-mode, in which inputs are received, sorted, and passed on.

What the leader has lost is not the capacity to make. It is the recognition that their own highest-value output is a made thing, with a maker’s requirements. They have been alienated from the craft nature of their own work.11 Judgement, synthesis, the ability to stay inside a hard problem until it yields: these are not the overhead around the real job, they are the job. Treated as overhead, they get the scraps of attention left once the calendar has taken its cut, and the scraps are not enough. When a difficult idea then arrives and will not go in, the natural move for someone who no longer believes thinking is work is to conclude that the idea, not the depleted attention receiving it, is at fault. The cost of switching is real and it compounds. Leroy (2009) showed that when we move between tasks a residue of the last one lingers and drags on the next, so a day chopped into fragments is not a day of many small productivities but a day spent mostly in the smear between them.12 [this para feels like we’re getting a bit lost. We’re talking too much about being a maker, and not enough about being a judge. The maker angle is great, and I think we should keep it but it’s disappearing down its own rabbit hole. the core of this argument is really about attention, and having what you need to be able to bring the force of that attention to bear on a problem. The following section on leisure needs to stay attached to that core idea, so it doesn’t just get too excited about leisure as a good in itself, or distracted down a deep-work rabbit hole, etc.]

What leisure was for

The Greek is scholē (the origin of our “school”)13 did not mean rest or amusement, it meant freedom from the pressure of necessity, the condition under which the highest activity, contemplation, became possible. Aristotle’s (ca. 350 B.C.E./2009) formula is that we are busy in order to be at leisure, not the reverse; work is for the sake of scholē, and to invert that is to mistake the means for the end. One concession before leaning further on him: the leisure Aristotle prized was for contemplation pursued as an end in itself, not for getting through a strategy paper faster. I borrow scholē for its shape, freedom from the pressure of necessity, and for its etymology, not to smuggle in a claim that leaders need philosophy. It is the shape the modern worker has lost, and it will hold deep reading, incubation or hard judgement equally well. The Latin word for leisure was otium, and their word for business, for the state of not being at leisure, was negotium, which is simply nec-otium, the negation of leisure. Business was defined, in the language itself, as the absence of the condition in which thought happens.

One thing to bear in mind is that Athenian leisure rested on people who had none, on enslaved workers and on women whose labour was not counted. Scholē was an unacknowledged class privilege before it was a philosophical ideal, and any argument that reaches for it has to sit with that.14 What makes the idea worth keeping is that the Greeks were right about what leisure was for even while being wrong about who deserved it. The uncomfortable question is not whether contemplative freedom is worth having but who gets to have it, and at whose expense.

Pieper (1948/1998) carried the idea into the twentieth century and named its enemy exactly. His argument in Leisure: The Basis of Culture is that leisure is not the reward that follows work but the precondition of any work worth doing, a stance of receptive openness in which real insight can arrive, and that a culture of “total work,” which grants legitimacy to nothing that is not visibly labour, corrodes the very faculty that thought depends on.15 Set against the senior leader who cannot afford to be seen doing nothing, Pieper is not quaint. He is describing the exact organ that manufactured incompetence removes.

The disciplines that kept a theory of this survived better. Mathematics and physics prize hard grinding, and they also honour the person lying on a sofa staring at the ceiling, because they have never confused the second with idleness. Wallas, a co-founder of the London School of Economics, set out the stages of creative thought a century ago, and the load-bearing one is incubation, the interval in which you deliberately stop working on a problem so the mind can work on it without you (Wallas, 1926).16 He drew it partly from Poincaré’s account of a solution to an abandoned problem arriving as he stepped onto a bus with his mind entirely elsewhere (Poincaré, 1908/1952). These fields have a doctrine that sanctions the empty afternoon. They can point to it and say that this is a stage of the work, not a lapse from it.

The creative professions have no such doctrine, and the reason is legibility rather than temperament. A proof either checks or it does not, so mathematics can be indifferent to how you reached it; the result vouches for the process after the fact. Design output cannot vouch for itself the same way. It is satisficing, in Simon’s sense, a good-enough choice pulled from a solution space far too large to search to the end, and nobody can show that this plan is the best plan, because the search that would prove it never terminates. Into that gap steps process as evidence: unable to prove the output is good, you prove instead that you worked hard for it, and hard work means visible hours. Architecture then adds a myth of its own, the heroic gesture, the master’s sketch thrown down whole on a napkin, which worships the instantaneous flash and so credits neither the long grind nor the slow incubation. The field ends with the worst of both cultures. It will not count thinking as work, and it will not count patience as thinking.

What it costs, and to whom

There is an economics to this that is more than metaphor. Cyert and March named organisational slack decades ago and argued that it is not waste but reserve, the spare resource that lets a firm absorb a shock or pursue something new instead of merely surviving the day (Cyert & March, 1963).17 DeMarco put it more sharply, borrowing from queueing theory: as any system nears full utilisation its ability to respond does not fall away gently, it collapses, because a queue at a hundred percent has nowhere to put the next arrival (DeMarco, 2001).18 An organisation that runs its people at total capacity has optimised away the very thing that lets it think and adapt, and has done so while congratulating itself on efficiency.

The name for the loss is X-inefficiency. Leibenstein coined it for firms that produce less than their inputs allow, not by misallocating resources in the textbook sense but through slack inside the organisation, effort withheld, attention misspent (Leibenstein, 1966).19 Usually the word slack is an accusation, and there is a tension worth naming rather than smoothing over: Leibenstein’s slack is the disease, and I am about to call a kind of slack the cure. They are two different things wearing one word. Idle effort is waste. Reserved attention, held so that thought and response stay possible, is not. A regime that stamps out every visible gap removes both, and in removing the second it lowers the output it set out to raise. Running people at full tilt does not maximise what they produce. It maximises what they produce that can be seen.

That the loss is real and measurable is no longer arguable. The World Management Survey, run by Bloom and Van Reenen across tens of thousands of firms, found that management practice is strongly tied to productivity, profitability and survival, that badly managed firms form a long persistent tail, and, in the largest study, that management practices account for more than a fifth of the variation in productivity between plants, a share comparable to or larger than research spending, technology or workforce skill (Bloom & Van Reenen, 2007, 2010; Bloom et al., 2019).20 Management is not the soft residue left over once the real inputs are counted. It is one of the real inputs, and how a leader spends their attention is much of what the word means.

If firms routinely produce below their potential, then society gets less than it could from the same people, materials and time, and the shortfall is real output that never came into being. I am inclined to go one street further and say that because the state supplies so many of the inputs, the educated people, the infrastructure, the stable institutions, a chronically under-producing private sector returns less to the state than it received, which shows up as a tax burden heavier than it needed to be and private exchanges thinner than they might have been, a slow leak in the collective account.21 That last step is mine, and I hold it more loosely than the rest; the economics I can cite stops at the firm. The firm-level claim alone is enough to make the point uncomfortable. The leader who cannot find an hour to think is not indulging a private vice. They are a small recurring loss in a very large ledger.

I keep returning to a detail from my own trade. We do not, for the most part, bill clients by the hour. We agree a fee for a phase of work and live with the difference between that fee and what the work actually costs us; the timesheets we keep are internal. On paper this is outcome pricing, and it ought to free us from the tyranny of the billable minute. It does not, quite, and I have started to suspect why. Under a fixed fee, an hour spent thinking rather than producing is not merely unbillable, which would make it invisible. It is worse than invisible, because it is a direct subtraction from the margin on a pot that cannot grow. The rational response to a capped fee is to compress the hours, and the hours easiest to compress are the quiet ones with nothing to show. So the instrument meant to buy us freedom to think may be the one most efficiently taxing the thinking away. I do not know that this is true. I know it is the shape of the thing I feel.

There is a version of this that ends well. We are building machines to do the producing, and if the old excuse for filling every hour was that the hour could be spent making something, that excuse is dissolving. The freed capacity could go to the thing the making was always meant to serve, deciding what is worth doing and thinking hard about whether we are doing it. It could equally be swallowed whole and poured back into doing more, faster, because the reflex that reads an empty hour as waste will not retire simply because the work has changed. The Greeks bought their leisure with other people’s unfreedom. We may be about to buy ours with machines, and the open question is whether we will have kept the faculty to use it, or whether we will only have found new hours to fill.

We have built work that depends, at its most valuable, on unhurried attention, and then arranged our institutions so that unhurried attention is the one thing a serious person may not be seen to take. The senior person skimming the difficult idea is not failing at the job. They are succeeding at the job we actually set, which is to appear fully occupied at all times, and that success is what makes the other job, the real one, impossible. Negotium was the negation of leisure. We have built a whole economy of it and called the negation the work.

  1. Peter and Hull (1969) argued that in a hierarchy people rise to their “level of incompetence” and stop, each promotion continuing until it reaches a role the person cannot perform. The mechanism is a ratchet: past success predicts the next promotion but not success in the differently shaped job it leads to. Manufactured incompetence is a different animal, and the difference matters. Peter’s manager is genuinely unable; mine is able and prevented. If Peter is right, the fix is better promotion decisions. If I am right, better promotion decisions barely touch it, because the same able person would be blocked either way. The two can of course afflict one unlucky person at once. 

  2. I need to reference this paper properly, and discuss it in a sidenote. Bastin et al. (2019), “The global tree restoration potential” published in Science. You should note that subsequent comments (e.g., Lewis et al., 2019) pointed out that the paper overestimated carbon storage capacity and downplayed ecological risks like disrupting native grasslands. 

  3. needs to be referenced properly. Everything should be made as simple as possible, but not simpler” is widely attributed to Einstein, but it is actually a paraphrase of a line from his 1933 Herbert Spencer lecture: “It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.” You can use the popular paraphrase but note its origin in a footnote. 

  4. The figures come from Taking Responsibility: Why UK plc Needs Better Managers (Chartered Management Institute, 2023), a YouGov study whose management sample was 2,524 people with management experience, fielded in June 2023. Two honest qualifications. It is UK data, and “no formal training” is self-reported, so it counts the absence of a credential, not the presence of incompetence; a well-mentored manager with no certificate reads as untrained here. My argument supplies the reason the untraining matters; the survey does not. The same research carries a detail that fits the promoted-for-the-wrong-reasons thread: 46% of managers believed colleagues had won promotion on internal relationships and profile rather than ability. 

  5. Newport (2024) is the most prominent recent treatment and names the disease cleanly. It comes with a caveat worth passing on rather than burying: a recurring criticism is that he runs “knowledge workers,” “creative workers” and “scientific researchers” together when the work differs in kind, and the sofa that serves a theoretical physicist may not transfer to a manager clearing a queue. That objection is useful to this argument rather than damaging, because the transfer question is exactly what the later section on legibility is trying to answer. 

  6. “Election” is Calvin’s own term, and Weber (1905/2001) builds the whole thesis on it: the doctrine of predestination held that salvation was already decided and unalterable, which left believers with no way to earn grace and every incentive to look for evidence they already had it. Steady, ascetic diligence in a worldly calling became that evidence. The mechanism is an “elective affinity,” in Weber’s careful phrase, not a simple cause: Protestantism did not invent capitalism, it supplied a disposition that capitalism could use. I take Weber here as genealogy, to explain how the moral charge first attached to visible labour, and treat Bellezza et al. (2017) as the live present-day mechanism. Stacked as rival causes the two would compete; used as origin and engine they do not. 

  7. Bellezza et al. (2017) found the status inference is mediated by perceived scarcity: the busy person is read as in demand, therefore valuable. The effect is not universal, which is the interesting part for anyone hoping it might shift. It was moderated by belief in social mobility and varied by culture, stronger in the United States than in parts of Europe, where a visibly leisured life still carries more status. Busyness-as-status is a belief, not a law, and beliefs move. The paper is a deliberate inversion of Veblen (1899), whose leisure class signalled rank by conspicuous abstention from labour, a class that did not have to work at all. Worth keeping straight: these are not the same people flipping their behaviour but a different class, the salaried professional, adopting the opposite marker. 

  8. Simon’s formulation, from a 1971 essay for a symposium on computers and the public interest, is that a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the sources that might consume it. It predates the conditions that made it obvious. Its use here is to move “attention” out of the soft, psychological register and into the economic one, a scarce resource with an allocation problem, which is the register the essay’s economics later works in. It is the same Simon who gave us “satisficing,” which returns in the section on design. 

  9. Graham (2009) is an essay, not a study, and argues from direct experience of running Y Combinator while trying to write and build. Its strength and its limit are the same: it is candid about resting on observation rather than data. His office-hours device, clustering all meetings at the end of the day to keep the morning intact, is the most-copied practical response, and it is telling that his own solution treats maker-time as the thing to defend and manager-time as the necessary intrusion, not the reverse. 

  10. This is a deliberate departure from Graham. He types people; I type modes, because typing people licenses the very fatalism the essay argues against (“I’m a manager now, the makers are the ones downstairs”). If the line runs between modes the same person occupies, then a senior leader’s inability to enter maker-mode is a solvable feature of the schedule rather than a fixed feature of the role. Whether it is solvable in practice, given the board-shaped constraint above, is the question the essay leaves open. 

  11. I mean “alienated” in something close to its original sense, separated from the product and nature of one’s own labour, no longer recognising it as one’s own making. The point does not need the full apparatus. It needs only the observation that a person who has stopped experiencing their strategy work as making will defend the time it takes about as well as they defend a coffee break, which is to say not at all. 

  12. Leroy (2009) called it attention residue: after a switch, part of one’s attention stays snagged on the previous task and performance on the new one suffers until the residue clears. The consequence is that the cost of a fragmented day is not linear in the number of interruptions. Each switch leaves a tail, the tails overlap, and ten context switches do not levy ten small taxes so much as leave the day smeared. 

  13. The etymology is not decoration. Scholē (σχολή) is the direct ancestor of “school,” by way of Latin schola: the place of learning is named for the leisure that made learning possible. The Aristotle for the argument is the Nicomachean Ethics Book X, on contemplation as the highest activity, and the treatment of leisure and education in the Politics Books VII and VIII. The claim that we are busy in order to be at leisure (ascholoumetha hina scholazōmen) is his, and it is the exact reversal of the modern arrangement, in which leisure, when permitted at all, is justified as the recovery that makes one fit for more work. 

  14. The support structure that buys thinking time has never gone away; it has been institutionalised. The seventeenth- and eighteenth-century gentleman natural philosopher could think at leisure because a household, an inherited income and usually a wife ran the rest of his life for him. We have largely moved that arrangement into universities and research institutes, trading the amateur’s versatility for the specialist’s depth. The trade carries a cost the amateur did not pay: specialisation narrows the range of things a mind holds in view at once, and some of the most useful ideas come from holding distant things together. Whether AI restores a kind of generalist leisure, freeing people to think broadly again, or merely accelerates the demand to produce, is a question large enough for its own essay, and this one only circles it. 

  15. Pieper (1948/1998) wrote in the wreckage of post-war Germany against what he called the world of “total work,” and tied the loss of leisure to acedia, an old word for a restless inability to be at peace with oneself that disguises itself as diligence. The busy leader who cannot sit still with an idea is, in Pieper’s terms, not virtuous but acediac, filling every hour precisely because stopping is intolerable. Whether or not one takes his theology, the psychological portrait is uncomfortably recognisable. 

  16. Wallas (1926) named four stages, preparation, incubation, illumination and verification, building on Helmholtz’s earlier three and on Poincaré’s introspection. Two things are worth lifting out. First, he explicitly recommended building interruption into the workflow, starting several problems and deliberately leaving them unfinished, as a way to let incubation do its work: designed-in cognitive slack, argued in 1926. Second, that he co-founded the LSE is a small irony, given that the same institution’s later economists (Bloom and Van Reenen, note 18) would go on to quantify the productivity cost of the management culture that has no room for what Wallas described. The empirical picture on incubation is real but modest: a meta-analysis found the effect genuine but small and condition-dependent (Sio & Ormerod, 2009), and the neuroscience often marshalled here (the default-mode network’s activity during rest and mind-wandering, and its association with creative cognition; Beaty et al., 2014; Baird et al., 2012) is drawn from laboratory creativity tasks, not executives metabolising strategy. There is even a tidy experimental version of the sofa: walking, indoors or out, reliably raises divergent (idea-generating) thinking while slightly lowering convergent (single-answer) thinking, and the boost lingers after you sit back down (Oppezzo & Schwartz, 2014). Take all of it as suggestive analogy. The transfer from lab creativity to leadership judgement is unverified, and the argument rests on Wallas and Poincaré, not on the fMRI. 

  17. Cyert and March (1963) introduced organisational slack as resources beyond the minimum needed to keep the organisation running, and argued that far from being pure waste it is what lets a firm innovate, absorb bad years, and pursue projects that do not pay at once. It is the direct ancestor of the designed-slack argument and the conceptual cousin of Leibenstein (note 17), though the two point in opposite normative directions, which is the tension the body tries to resolve. 

  18. DeMarco (2001) is the operational core of the idea and its cleanest statement. The queueing point: where work arrives somewhat unpredictably, waiting time rises non-linearly with utilisation and heads for infinity as utilisation approaches a hundred percent. A road at full capacity is a car park. An organisation run at full utilisation has, by the same mathematics, destroyed its own responsiveness, and the slack it eliminated was the capacity to respond. 

  19. Leibenstein (1966) distinguished X-inefficiency from the allocative inefficiency economists usually model, and suggested it may be the larger loss by a wide margin, with some later estimates putting X-inefficiency losses at a multiple of the classic deadweight triangle. The awkwardness for me is that Leibenstein treats internal slack as the pathology competition exists to discipline away, whereas I am defending a kind of slack. The reconciliation, in the body, is that “slack” names two things: effort withheld (waste) and attention reserved (productive capacity). My claim is that the busyness regime cannot tell them apart and so destroys the second while hunting the first, producing X-inefficiency in Leibenstein’s own sense. It is arguable, and I would rather leave the argument visible than paper over it. 

  20. The World Management Survey findings run across a programme of work: a strong association between management practice and firm-level productivity, profitability and survival, with wide variation across and within countries and a long tail of badly managed firms (Bloom & Van Reenen, 2007); the case that persistent productivity differences between firms and nations largely reflect management practice (Bloom & Van Reenen, 2010); and, from a study of roughly 35,000 US plants, the finding that structured management practices account for more than 20% of the variance in productivity, comparable to or greater than R&D, information technology or human capital (Bloom et al., 2019). The measure is noisy and the direction of causation is not fully settled, but the weight of evidence that management is a first-order input rather than a residual is now considerable. 

  21. This paragraph is my own extension, and I flag it as speculation rather than citable economics. The firm-level loss, real output foregone, is well supported. The move to “therefore the state’s return on its inputs is lower, therefore taxes are heavier than needed, therefore a vicious cycle” adds causal steps that neither Leibenstein nor the World Management Survey licenses, and a careful economist would want to model, among other things, where the foregone output would otherwise have gone and whether the state actually bears the residual. I include it because it is the shape of my intuition about why this is not merely a firm’s private problem, not because I can stand it up. The modest version, which I do stand behind: firms systematically under-produce relative to their potential, management is a large part of why, and the shortfall is borne by everyone downstream of the firm.
