In a training room in Johannesburg in the early 1990s, I watched a graduate intake sit a standard battery of reasoning tests. Matrices. Sequences. Abstract shapes rotating in ways that meant nothing until you found the rule, and then meant everything. The exercise was timed, that is the exercise was designed to punish anyone who paused to ask why the rule mattered before hunting for it.

One candidate finished early and scored well. Another finished late, guessed at the last six items, and scored badly. On paper the first candidate had what we westerners so admire; the sharper mind. In the boardroom eighteen months later it was the second candidate who had quietly restructured a supply relationship across three extended families, four dialects and a set of obligations that had nothing to do with the org chart and everything to do with why the deal actually closed. Nobody had trained him to do that. Nobody had tested for it either, because you can't.

I have thought about those two candidates for thirty years, because the test didn't lie, exactly. It measured something real. It just wasn't measuring the thing that mattered in that boardroom, and it wasn't measuring the thing that mattered because it wasn't built to.

The truth is that measured cognitive test gaps between populations are real, replicated, and damn stubborn. Add to that that almost nobody is allowed to discuss the first fact without being sorted, instantly, into one of two camps which, incidentally, both get the answer wrong.

Camp one denies the gap exists, or insists it is entirely an artefact of test bias, poverty and measurement error, full stop, nothing more to see. Camp two — smaller, louder in the wrong rooms, and considerably more dangerous — concludes the gap is etched into the genetic code, and that the ranking on a 1930s puzzle-solving instrument tells you something eternal about human worth. Denial and hereditarianism. Two doors into the same locked building. And both assume the test is measuring intelligence itself, in the abstract, the way a thermometer measures heat.

It isn't.

That is the whole essay in one sentence. The gap is real, and it measures something important, but that something is cultural training in a specific temporal orientation, not innate capacity. The question is not and was not who is smarter. The question is what cognitive habits a culture drills into its children, generation after generation, and why some cultures drill in one set and some drill in another.

The clock nobody sees

I have written before about the hidden clock every civilisation carries inside it. The largely unconscious answer each culture gives to the question of what TIME is for. Some cultures treat time as a resource: finite, spendable, investable, wastable, the thing you are called to account for on Judgement Day or in the quarterly review - something that can be managed. Others treat time as something that just IS; a field of relationships to be inhabited — the ancestors present, the seasons cyclical, the obligation to the living kin outweighing the appointment in the diary and an accumulation of events. Neither orientation is a moral failing, and one is not better than the other. Both are load-bearing structures, and you can no more choose to "just" have the other one than you can choose to speak a language you were never taught.

That distinction shapes far more than punctuality. It shapes what a culture considers worth maintaining before it breaks, what it teaches a seven-year-old to plan for, what counts as wisdom versus what counts as superstition, and which institutions a society can run without them collapsing into corruption or farce. A future-oriented culture builds bridges with maintenance schedules. A past-oriented culture builds relationships that will feed you when the bridge, and the job, and the pension fund, are all gone. Both are rational. Both are answers to different environments. The mistake everyone keeps making — is grading one answer against the other's exam.

Three clocks, three civilisations

Look at three broad cultural logics side by side and the pattern gets hard to unsee. (And note, I use the word 'culture' very loosely to describe large groups of people that share a common trait, not in the narrow, modern definitional sense that aligns with country borders.)

The modern West runs on linear, future-oriented time. The past is something to be overcome, cited only when it authorises progress. Maintenance is a virtue — the entire apparatus of insurance, retirement saving, preventative medicine and infrastructure audit exists to defend an imagined future against a present that would rather spend the money now. Time is moralised. Wasting it is close to sin.

East Asia complicates this immediately, and usefully. Ancestral reverence sits fused with brutal future-discipline — the examination system, the twelve-hour study day, the multi-generational family project of climbing. The past is not overcome here; it is owed. Confucian filial piety doesn't say "forget your grandfather and build the future." It says "honour your grandfather by building a future worthy of him," which turns out to generate exactly the same deferred-gratification cognitive habits as the Protestant work ethic, from a completely different theological starting point.

Africa and most Indigenous cultures run a third clock: relational, event-oriented, the past a living presence rather than a closed chapter. Time is not a river running one direction toward a destination. It is a field you stand in, thick with the dead forefathers and spirits and the unborn and the cousin who needs your cattle this week regardless of what the calendar says. Continuity is valued over transformation, because continuity is what has kept the group alive through droughts no five-year plan could have predicted.

I want to be honest about what this is not and what it isn't. I am simply offering a hypothesis that explains the world. I am not offering the solution - it is complicated - and I am most definitely not ranking these differences. What I am expounding here are cultural logics, not racial destinies. A Nigerian software architect in Lagos may well run a tighter Gantt chart than most Sydney project managers I have worked with. A fourth-generation Boston Brahmin can be as present-bound and improvident as anyone. Individuals contradict the pattern constantly, cheerfully, and in large numbers. But the pattern (I believe) still exists at the population level, the way a national cuisine exists even though plenty of individuals in that nation hate the national dish. Culture is emergent, not deterministic, and this distinction is important.

What the test actually tests

Now go back to that boardroom, and ask what an IQ test rewards. Abstract reasoning stripped of context. Speed under artificial time pressure. Sequential logic. Categorisation of objects that have no relationship to the test-taker's actual life. Hypothetical thinking about scenarios that do not exist and may never. We all know how useful any and all of these abilities can be.

These are not universal cognitive endowments, handed down from Sinai along with the Ten Commandments. They are the specific reflexes of a future-oriented, bureaucratised, maintenance-heavy society — a society that has spent centuries training its children, from primary school onward, to solve decontextualised puzzles at speed because that is precisely the skill its factories, its exams, its actuarial tables and its air-traffic control towers require. We are all aware of the discontent with the current schooling system (in the West) with a rise in homeschooling, and declining prestige of Universities. That is proof of both that the schooling is designed to prepare you for a certain future, AND proof that, looking into that future, large numbers of people are recognising that it needs to change.

The test was built by one temporal culture, to select for that culture's own institutional needs, using items normed on that culture's own children. Using the resulting instrument to rank a different temporal culture's cognitive output is not measurement. It is grading a fish on tree-climbing and writing "disappointing" in the margin — except somebody in this analogy built the tree, and it wasn't the fish.

The West that scored seventy

Here is the finding that should have ended the hereditarian argument on its own, and somehow didn't: the West did not always score where it scores now.

James Flynn spent three decades documenting something almost nobody predicted — IQ scores climbing roughly three points per decade across the entire twentieth century, in every industrialised country he could get data for. Run the maths backward and a representative European sitting a modern IQ test in 1900, scored against today's norms, comes in around seventy. Seventy. That is the threshold for intellectual disability on the very same scale used today to sort populations into winners and losers.

Nobody sane thinks Europeans were, on average, cognitively impaired in 1900. Societies that produced an Archimedes or a Socrates or a Newton could not be labelled 'stupid'. What happened instead is that the West's own clock accelerated. Schooling extended. Abstraction-heavy work replaced manual trades. Tests, puzzles, categorisation games and hypothetical reasoning became the daily furniture of childhood in a way they simply were not for a farm boy in Yorkshire or a fisherman's son in Calabria.

Notice, too, where the Flynn gains concentrated. Largest on abstract, decontextualised reasoning — the exact muscle a modernising, credential-obsessed society trains hardest. Smallest on vocabulary and general knowledge, the parts of the test closest to raw accumulated fact rather than trained cognitive style. That is not what a fixed biological gap looks like. That is what a plastic cognitive habit looks like, responding to environmental demand inside one, maybe two generations (Flynn, 1984; 1987; 2007).

Think about that for a moment. The gap the twentieth century became obsessed with measuring between populations did not exist in some eternal, ordained form waiting to be discovered by psychometricians. It emerged as the Western clock sped up, not because the West was always ahead and everyone else was catching up. The West got here recently. It just forgot how recently.

The loop that feeds itself

None of this happens by decree. A culture's temporal logic generates concrete daily demands — plan for winter, service the bridge before it fails, educate the child for a job that doesn't exist yet. Meeting those demands trains specific cognitive habits: delayed gratification, abstraction, sequencing, risk modelling against an imagined future. Those trained habits get built into institutions — schools, courts, insurance markets, examination systems. And the institutions, once built, demand more of exactly those habits from the next generation, at higher intensity, with sharper tests.

And if you are a Westerner, like me, you read those traits and think they're admirable.

This loop is a virtuous circle, self-reinforcing, no central planner required. The genuinely interesting question isn't whether the loop exists. It's what lights the fuse — and, just as importantly, what snuffs it out. Because a loop that reinforces itself in one direction can just as easily reinforce itself in the other, and history has receipts for both.

Ignition, not destiny

Mankind is said to have originated from Africa. One explanation for the divergence in cognitive variance is climate determinism — temperate zones with harsh winters forced planning, storage and deferred investment onto their populations, full stop, mystery solved. There is a real seed of truth in it. Seasonal scarcity does select for exactly the habits this essay has been describing, and there is a case that the humans who migrated out of Africa into colder, harder latitudes were self-selected for risk tolerance and comfort with the unknown, because leaving is itself a bet on a future you cannot see.

But, that migration happened sixty thousand years ago. The temporal orientations under discussion here — Protestant work discipline, Confucian examination culture, the specific intensity of Western future-mindedness — are phenomena of the last few hundred to few thousand years, a rounding error against sixty millennia. Climate may well have been the proverbial butterfly flapping its wings; it loaded the gun but didn't pull the trigger. The trigger came much later, and it came from somewhere far more contingent than latitude.

Two different fuses, one fire

In Europe the fuse was theological. The Reformation did something climate never could: it turned future-orientation into a moral imperative, enforceable by the threat of damnation rather than merely the threat of a cold February. Work became calling. Idleness became evidence against your soul. Delayed gratification stopped being merely prudent and became evidence of election — proof, to yourself and your neighbours, that you were among the saved. Weber saw this clearly a century ago and got mocked for it in some quarters ever since, which tells you more about the mockers than about Weber. The future became judgement, salvation, proof and progress, all fused into a single motive, and that fusion ignited the virtuous circle at a civilisational scale. I'd even argue that preventative maintenance maps nicely back onto the notion of sacrifice.

East Asia lit the same fuse from an entirely different theological box. No damnation, no elect, no Reformation. Instead: filial piety, an imperial examination system running for over a millennium that could lift a peasant's grandson into the mandarinate on the strength of memorised classics and disciplined reasoning, and a state-building ambition that made the family's honour contingent on the son's future achievement rather than the family's past preservation. The ancestors, in this version, don't ask to be left alone. They ask to be exceeded. Same cognitive output — abstraction, delay, discipline, sequencing — reached by a completely different cultural road.

The variable doing the work in both cases is not race. It is what the inherited cultural logic demands of the people currently alive. Change the demand and, given enough generations, you change the cognitive habits the population trains into its children. That is not speculation. It is the plainest reading of two civilisations that ignited the same engine from opposite theological starting points and arrived at strikingly similar test scores five hundred years later.

When the clock runs backward

If you want the single strongest piece of evidence for everything argued so far, don't look at who ignited the loop. Look at who lit it, ran it brilliantly for five centuries, and then extinguished it themselves.

From roughly the eighth century to the thirteenth, the Islamic world was the most intellectually dynamic civilisation on earth, by a distance. Translating and preserving Greek philosophy while Europe had largely lost the thread. Inventing algebra — the word itself is Arabic. Building hospitals with wards, case notes and something recognisable as the clinical method centuries before Europe managed it. Running an early scientific method through figures like Ibn al-Haytham that historians of science now treat as a genuine precursor to the empirical tradition the West likes to claim it invented alone. This was not a civilisation lagging. This was the civilisation everyone else was trying to catch.

Then the theological climate was shifted by the Ash'ari school's occasionalism — the doctrine that causation itself is not a reliable feature of the universe but simply God recreating events moment to moment, so that fire does not really cause burning, God merely wills the burning each time in the customary presence of fire — winning its long argument against the rationalist Mu'tazila school. Al-Ghazali's Incoherence of the Philosophers landed as the decisive blow against the philosophical project itself, and it landed hard enough that it is still being argued about a thousand years later. The inherited cultural mandate flipped. The past stopped saying "seek knowledge even unto China," a saying attributed to the Prophet and genuinely central to early Islamic intellectual culture, and started saying, in effect, that the gates of independent interpretation were closed.

I am not going to pretend that single intellectual argument, on its own, toppled a civilisation's cognitive trajectory. Societies are complex systems and history is never that tidy, and anyone who tells you it is one cause, one book, one school of theology, probably also has an Eiffel tower to sell you. But, whatever the real cause, the direction of travel is unmistakable, and it runs exactly counter to the hereditarian story. The same population, the same genetic stock by any measure that matters, went from leading the world in innovation to falling behind it — not because the gene pool changed in three centuries, which is absurd on its face, but because the cultural clock did. The virtuous circle became a vicious one: less demand for independent reasoning bred less training in independent reasoning, which bred institutions with even less appetite for it, which bred the next generation's diminished demand. Temporal orientation, and the cognitive habits it trains, can ignite. It can also fade. Genes cannot do either.

The gap that won't hurry up

This is a question to grapple with: if temporal orientation is learned, why hasn't the Black-White cognitive test gap in America closed after a hundred and sixty years of freedom and integration?

Three answers, and I think all three are true simultaneously.

First, the clock on genuine institutional access did not start at emancipation. It started at desegregation — properly, functionally, in most of the country — somewhere in the 1960s and 1970s. If so, it means barely one full generation of anything resembling equal participation in the schools, credentialing systems and professional institutions that actually train the cognitive habits a modern test rewards. A hundred and sixty years sounds like a long time until you notice that a hundred and forty of them were spent under systems explicitly engineered to block the institutional access this whole essay says is the mechanism.

Second, culture transmits inside families and communities, generation to generation, largely beneath conscious awareness. A parent teaches a child what the parent was taught, not what a policy briefing says should now be taught. Centuries of slavery and exclusion did not simply restrict access to institutions from the outside. They shaped an inherited cultural stance toward those institutions — toward planning, toward trust in deferred reward, toward the very idea that the system would honour a bet placed today with a payoff decades away, because for most of that history it demonstrably would not. That inheritance does not evaporate the moment a law changes. It moves at the speed of parenting, which is slower than the speed of legislation.

Third — and this is the one that 'woke' will come and rap you on the knuckles for saying — there may be an active resistance dynamic at work, and it would be entirely rational if there were. Adopting the dominant culture's clock wholesale can feel like capitulation, like erasing the very identity that survived the centuries the dominant culture spent trying to erase it. That is not a pathology. That is a group protecting something it has every reason to protect, and any honest account of cultural change has to leave room for the fact that people sometimes correctly refuse the invitation to become someone else's idea of success.

Put the three together and the stubbornness of the gap stops being evidence against the cultural thesis and becomes exactly what the thesis predicts. The gap has narrowed — by most estimates somewhere in the order of three to six points since the 1970s. That is not proof of nothing. That is a trend line moving in precisely the direction a cultural explanation says it should, at precisely the plodding pace cultural transmission actually moves.

As an aside: I want to make a wild claim, backed by the gravitas of a thousand TikTok videos and zero research. I do this not to be contentious, but to illustrate how the theories I laid out above seem to be playing out at present. The US in particular is at a cross-roads. Racial tensions were (many unverified charts I have seen) on the decline in the 90s, and after the election of Obama, started rising sharply.

As I write this, there is a lot of chatter about 'black fatigue' as a response. Integration has stalled, and there is an elevated focus on 'race'. That is the irony of (well-intentioned but misguided) movements like Black Lives Matter. This is further fueled by failed DEI initiatives that are experienced as punishment for a past they don't control and obstacles to a future they want. The beneficiaries of 'affirmative action' feel entitled to reparations, advancement, status and rewards because past suffering owes them this. Note how the one group looks forward, and the other backwards?

(Whilst I am happy to defend my personal views, please note that in this article I am describing a particular dynamic, and getting into an argument about which is better or worse will distract from the main point I want to make.)

The circle the hereditarians can't see

There is a deeper problem here than any single data point: if IQ tests measure the cognitive habits of modernity, and modernity was built by the cultures that spent the longest training those specific habits, then using IQ scores to rank cultures against each other is circular in the most literal sense of the word. You are measuring a culture's fluency in a tradition, using an instrument built by that same tradition, and then presenting the result as a discovery about biology rather than a description of the ruler.

The hereditarian position depends entirely on missing this. It treats a measurement artefact — a score on an instrument calibrated to one civilisation's institutional demands — as though it were a direct readout of brain hardware, the way a scale reads weight regardless of what country you're standing in. It isn't. The scale in this analogy was built on Earth, calibrated to Earth's gravity, and then shipped to measure the inhabitants of the Moon with a straight face.

What each clock sees, and what it misses

The modern West's clock produced staggering wealth, modern medicine, mass literacy and political freedoms that would have been unimaginable to a serf. It also produced alienation on an industrial scale, pornography, ecological destruction as an unplanned side effect of relentless future-discounting, and a low background hum of dissatisfaction that comes from a culture structurally incapable of believing the present is ever quite enough. Ask a Westerner how they're doing and the honest answer is usually "busy" — which is a temporal complaint, not a factual one.

Traditional and relational cultures hold onto truths modernity keeps misplacing: that belonging outranks optimisation, that land is not simply an asset on a balance sheet, that the dead still have standing in the decisions of the living, and that not every limit is a problem waiting for an engineer. Those same cultures, honestly assessed, struggle to run hospitals, airports and high-trust bureaucracies at the scale and reliability modern life now assumes as a baseline. That is not an insult. It is the tragic flip side of the same coin — the coldness a system needs to run at scale is close cousin to the coldness that erodes the very relationships a present-oriented culture exists to protect.

Different clocks reveal different truths about what it is to be a person living inside time. None of them is the complete picture. Anyone selling you the complete picture is selling you their own clock with the label removed.

I have used the word 'culture' loosely to describe different groups of people. It would be remiss of me not to mention that different groups within one 'culture' would likely exhibit different temporal perspectives. I suspect (based on intuition rather than evidence) that women, for instance, would generally also lean towards a more relational, past-oriented culture. (And jokes about why women never forgive would not be appropriate here 🙂)

Learning to speak two times

Go back to that boardroom one more time. Two candidates, one test, two entirely different forms of intelligence, neither one visible to the other's instrument.

The most hopeful thing I can tell you is that people are not sentenced to one clock for life. They can become bilingual in time, the way a child raised in two households learns to code-switch between two languages without either one erasing the other. An African migrant can master the Western calendar, the deadline, the mortgage amortisation schedule, without abandoning the ancestral obligations that gave his life its shape before he ever saw a spreadsheet. An Indigenous community can run modern infrastructure, modern medicine, modern schools, while keeping sacred continuity fully intact underneath it. I have watched both happen. Neither transition required the person to stop being who they were.

None of this is an argument that one temporal culture should defeat the others, and I want to be clear on the point I suspect some readers will still try to smuggle past me on the way out the door: I am not arguing that any one of these clocks is better or worse than the others. I am arguing that each was best suited to the environment that produced it — for it, and by it — unless and until that environment changes enough to demand adaptation. A culture built to survive drought-and-kinship conditions is not a defective version of a culture built to survive industrial bureaucracy. It is a correct answer to a different exam.

So the question this essay set out to answer was never who is ahead. It was always the other question, the one that actually invites you to wrestle with it: what does each way of being in time make possible, and what does it cost to leave on the table? Ask that question instead, and the gap stops being a scoreboard. It starts being a map — of two candidates, one room, and a test that was only ever telling you about itself.

And it becomes a map for a conversation we desperately need.
