The World’s Long Habit of Proving Us Wrong

For reasons I have never understood, people like to hear that the world is going to hell.
— Deirdre McCloskey

Every generation quietly arrives at the same conclusion.

The world, it believes, has become unusually fragile. Society has lost its way. The institutions that once held everything together are beginning to crack. Technology is changing people faster than they can adapt. Moral standards are declining. Politics has become irredeemably broken. Somehow, history has chosen this particular moment to begin unravelling.

The names of the crises change. The emotions rarely do.

That thought occurred to me while reading about one of the most devastating disasters in England’s history.

On the morning of 2 September 1666, a fire broke out in the bakery of Thomas Farriner on Pudding Lane in London. At first, it seemed no different from countless other fires that periodically troubled a medieval city built largely from timber. Houses leaned precariously over narrow streets. Open flames heated homes, illuminated rooms and powered ovens. Sparks were an accepted risk of urban life.

This spark, however, found the perfect conditions to become something else.

Driven by strong easterly winds, the flames spread from rooftop to rooftop with astonishing speed. Within hours, entire neighbourhoods disappeared. By the time the fire was finally brought under control four days later, more than thirteen thousand homes, dozens of churches, civic buildings and much of medieval London had been reduced to ashes. Tens of thousands of people had lost everything they owned. Smoke darkened the sky for days. Rumours travelled faster than facts. Foreigners were assaulted because frightened societies have always searched for someone to blame before searching for an explanation.

Standing on the banks of the Thames that week, watching one of Europe’s greatest cities disappear into smoke, it would have been difficult to imagine a hopeful future. Catastrophe has a way of shrinking our imagination until tomorrow appears incapable of existing.

Yet history rarely behaves the way it looks in the moment.

The Great Fire did not become the end of London. It became the beginning of a different city. The reconstruction fundamentally changed urban planning. Building regulations became stricter. Brick and stone gradually replaced timber. Streets widened. Fire prevention improved. Insurance markets expanded. Out of one of England’s greatest disasters emerged a city that proved stronger, safer and more resilient than the one that had burned.

No one watching the flames could have predicted that outcome.

That is the peculiar disadvantage of living through history. We experience uncertainty in real time, while future generations inherit neatly edited narratives in which every crisis already has an ending. To us, the Black Death feels survivable because we know Europe eventually emerged from it. The Second World War appears comprehensible because we already know who won. The Cuban Missile Crisis occupies only a few pages in a history book because we know nuclear war never came.

The people living through those moments possessed no such certainty.

When Soviet ships approached Cuba in October 1962, there was no invisible narrator reassuring ordinary families that civilisation would survive another week. Parents still took their children to school. Offices still opened. Shops still traded. Governments quietly prepared for possibilities no one wished to imagine. Looking backwards makes resilience seem inevitable. Living forwards never does.

Perhaps this is why every generation becomes convinced that it inhabits history’s most dangerous moment. We mistake our proximity to uncertainty for evidence that uncertainty itself has become unprecedented.

The more I read journals, speeches and letters from previous centuries, the more familiar they began to sound.

Marcus Tullius Cicero lamented the decline of civic virtue. Seneca worried that wealth and luxury had weakened Roman character. Juvenal mocked the obsession with entertainment and superficiality. Medieval clerics complained about moral decay. Victorian intellectuals feared that industrialisation would destroy the family. Parents in the 1950s believed comic books would corrupt children. During the Cold War, millions genuinely expected nuclear annihilation. At the turn of the millennium, governments and corporations invested billions preparing for the Y2K computer bug, convinced that modern infrastructure might collapse when the calendar changed.

Today we speak instead of artificial intelligence, climate change, political polarisation and demographic decline.

The vocabulary changes.

The emotional pattern does not.

This does not mean previous generations were foolish. Many of the people who feared decline were among the most intelligent minds of their age. Cicero was one of history’s greatest statesmen. Seneca remains one of its finest philosophers. Thomas Malthus, whose prediction of inevitable famine would shape economic thought for generations, was neither irrational nor mathematically careless. His calculations were elegant. They simply rested on one assumption that history repeatedly punishes: that tomorrow will resemble yesterday.

Human beings have always been far better at extending present trends than imagining future inventions.

Malthus could calculate population growth with remarkable precision, but he could not foresee mechanised agriculture, synthetic fertilisers or the Green Revolution. The engineers who built the earliest computers understood computation, but few imagined billions of people carrying pocket-sized supercomputers connected to a global network. The Wright brothers solved the problem of flight without fully appreciating how aviation would transform commerce, diplomacy and war.

History does not merely surprise us.

It exposes the limits of our imagination.

And yet, despite centuries of evidence, intelligent people continue to believe that their own generation occupies a uniquely fragile moment. Perhaps the problem lies not with history itself but with the machinery through which we experience it. The question, then, is not why civilisation repeatedly appears to be collapsing.

The more interesting question is why our minds find collapse so much easier to believe than recovery.

There is a reason this pattern has repeated itself for so long, and it has remarkably little to do with politics, economics or technology. It begins inside the oldest piece of equipment every human being carries — the brain. Long before newspapers, television channels or smartphones competed for our attention, evolution had already decided what would capture it. The human mind was never designed to provide an objective account of reality. It was designed to maximise the probability of survival.

Imagine two hunter-gatherers walking through a forest forty thousand years ago. One notices birds singing, the colours of the trees and the warmth of the morning sun. The other notices broken branches, unusual silence and fresh animal tracks pressed into the mud. Which one is more likely to survive? Evolution answered that question long before psychology existed as a discipline. The ancestors who paid greater attention to danger were more likely to live long enough to pass on their genes. The ones who ignored warning signs, however beautiful the landscape around them, often did not.

That ancient survival mechanism still governs us today. The difference is that the forests have disappeared while the threats have multiplied. Instead of scanning the horizon for predators, we refresh news feeds. Instead of listening for movement in the undergrowth, we monitor inflation, elections, cyberattacks, pandemics and algorithms. Our environment has transformed almost beyond recognition in the last few centuries. Our nervous system has not.

Psychologists refer to this tendency as negativity bias. Daniel Kahneman spent much of his career demonstrating that losses affect us more deeply than equivalent gains, that uncertainty weighs more heavily than reassurance, and that the human mind consistently overestimates danger because, throughout most of our evolutionary history, underestimating danger carried devastating consequences. The point is subtle but important. Our ancestors evolved to survive the world, not to see it accurately.

Once you begin looking through that lens, modern media starts making a different kind of sense. Journalism has never been dishonest simply because it reports tragedy. Its purpose has always been to identify what is unusual. A bridge that remains standing is not news. A bridge that collapses becomes an international headline. One commercial aircraft crashing dominates global attention. The hundred thousand that land safely the same day disappear into statistical silence. We do not read headlines announcing that billions of people reached home safely, that hospitals quietly completed thousands of successful surgeries overnight, or that millions of children returned from school without incident. Normality has never been newsworthy because normality does not interrupt the pattern.

The problem arises when we mistake a catalogue of exceptions for a description of everyday life. The more extraordinary events we consume, the more ordinary they begin to feel. A reader who spends every morning absorbing wars, disasters, political crises and economic uncertainty can gradually begin to believe that catastrophe has become the defining feature of civilisation rather than one of its recurring interruptions. The distortion does not lie in any single story. It emerges from their accumulation.

Hans Rosling devoted much of his life to exposing precisely this misunderstanding. Wherever he travelled — whether addressing physicians in Stockholm, students in London or executives in New York — he would begin by asking a handful of remarkably simple questions. How many girls in low-income countries finish primary school? What proportion of the world’s population lives in extreme poverty? How many children receive routine vaccinations? The audiences were almost always highly educated. They were also almost always wrong.

Rosling found that fascinating because their mistakes were rarely caused by ignorance. They were caused by information. People consumed so much news about conflict, disease and disaster that they quietly lost sight of long-term trends. They confused visibility with frequency. They assumed that because suffering occupied more space in public conversation, it must also occupy more space in reality.

He resisted being called an optimist. “I am not an optimist,” he once remarked. “I am a very serious possibilist.” It is a distinction worth preserving. Optimism without evidence is sentimentality. Pessimism without evidence is performance. Neither helps us understand the world. History asks for something more demanding. It asks for intellectual humility — the willingness to let evidence overrule instinct.

And the evidence tells a story that surprises many people. Over the past two centuries, extreme poverty has declined dramatically. Child mortality has fallen to levels previous generations would have considered miraculous. Literacy has expanded across almost every region of the world. Smallpox, once responsible for hundreds of millions of deaths, has disappeared altogether. Polio, which terrified parents for much of the twentieth century, stands on the edge of eradication. Average life expectancy has increased by decades in many countries, not because human beings suddenly became wiser, but because generations of scientists, engineers, physicians, teachers and reformers quietly solved one problem after another.

None of this suggests that suffering has vanished. Wars continue. Disease remains. Climate change presents one of the defining challenges of our age. Artificial intelligence raises profound ethical and economic questions. Political instability continues to test democracies around the world. History has never been a march toward perfection. It has been something far less dramatic and, perhaps for that reason, far more remarkable: the gradual accumulation of solutions.

The difficulty is that solutions possess an unusual characteristic. Once they become part of everyday life, we stop noticing them. No one wakes each morning filled with gratitude that cholera no longer defines urban existence in much of the developed world. We do not marvel at clean drinking water because we have forgotten that, for most of human history, a simple glass of water could carry a death sentence. We complain about waiting times in hospitals without reflecting on the fact that previous generations expected infections, childbirth and minor injuries to claim lives with frightening regularity.

Progress suffers from an extraordinary disadvantage. The moment it succeeds, it disappears into the background of ordinary life. It becomes invisible precisely because it has become normal.

That, perhaps, is why history so often feels darker than it really is. We inherit the victories of previous generations without remembering the battles that produced them, while confronting our own unfinished problems in real time. Yesterday’s triumphs become today’s expectations. Today’s failures dominate tomorrow’s headlines.

The comparison could never be fair.

The Scottish philosopher David Hume once observed that habit is the great guide of human life. We adapt to almost everything — not only to hardship, but also to improvement. It is one of the most extraordinary features of the human mind. The very things that would have astonished our ancestors eventually become so commonplace that we stop seeing them altogether.

That forgetting has consequences.

Ask someone to identify humanity’s greatest achievements and they are likely to mention the internet, artificial intelligence, the moon landing or perhaps antibiotics. Very few will mention clean drinking water. Fewer still will mention underground sewage systems. Almost nobody will think of refrigeration, food safety regulations or soap. Yet if historians were asked to rank the innovations that most profoundly altered the human condition, these quiet revolutions would deserve places near the very top.

History remembers conquerors.

Civilisation is often built by engineers.

Before the nineteenth century, cities were dangerous not because enemies stood outside their walls, but because disease flourished within them. Human waste flowed through open streets. Wells were contaminated. Cholera, dysentery and typhoid returned with terrifying regularity. A child who survived infancy could still die from drinking the wrong bucket of water. Mothers accepted the possibility of losing children because the alternative was emotionally impossible. Death was woven into ordinary life in ways that are almost unimaginable today.

The remarkable thing is not that these conditions disappeared. It is that they disappeared so completely from everyday experience that we scarcely remember they existed.

Turn on a kitchen tap almost anywhere in the developed world and clean water appears with astonishing reliability. It requires no ceremony. We scarcely acknowledge the engineering beneath our feet or the generations of scientific discovery that transformed a luxury into an expectation. Every civilisation inherits technologies that eventually become so ordinary they cease to feel like technologies at all. They simply become the way the world works.

Medicine followed a remarkably similar path. Ignaz Semmelweis noticed, in the maternity wards of Vienna during the 1840s, that doctors who washed their hands before delivering babies dramatically reduced maternal deaths. His observations were careful. His data were persuasive. His colleagues dismissed him. Many were offended by the suggestion that their own hands might be responsible for the deaths of their patients. Semmelweis died long before the medical profession embraced the practice that would eventually save millions of lives.

There is something profoundly humbling about that story. One generation rejected an idea that the next would consider obvious. Progress often asks society to accept truths that initially feel absurd. Looking backwards, discovery appears inevitable. Living through it, it usually feels controversial.

The same lesson emerges from agriculture. In 1798, Thomas Robert Malthus argued that population growth would inevitably outstrip humanity’s ability to produce food. His reasoning was mathematically elegant. It was also deeply persuasive. For generations, famine seemed destined to become civilisation’s defining challenge. What Malthus could not anticipate was not an error in arithmetic but an explosion of imagination. Mechanised farming, synthetic fertilisers, improved irrigation, plant genetics and Norman Borlaug’s high-yield wheat varieties transformed agricultural productivity on a scale almost without precedent. Hundreds of millions of people are alive today because someone imagined that harvests did not have to obey the limits of the past.

History repeatedly exposes the same blind spot.

We are remarkably good at predicting the continuation of existing trends.

We are remarkably poor at predicting invention.

That distinction matters because nearly every major forecasting error in history has emerged from confusing the two. Economists projected horse populations without anticipating automobiles. Engineers improved telegraph systems without imagining smartphones. Physicians catalogued infectious diseases without foreseeing antibiotics. Every generation extends the present into the future while quietly overlooking the possibility that the future may invent entirely new rules.

Perhaps this explains why history often feels more pessimistic while it is unfolding than it does in retrospect. We remember wars because they interrupt civilisation. We remember financial crises because they disrupt prosperity. Yet we rarely remember the decades during which engineers quietly improved bridges, scientists refined vaccines, teachers expanded literacy or municipalities laid sewer pipes beneath growing cities. These achievements rarely possess dramatic beginnings or satisfying endings. They accumulate slowly until an entirely different society emerges almost without noticing its own transformation.

Steven Pinker has argued that one of humanity’s greatest misconceptions concerns violence itself. Judged by headlines, the modern world often appears exceptionally dangerous. Judged over centuries, however, homicide has generally declined, judicial torture has largely disappeared, slavery has become morally unacceptable across much of the world and the legal rights of women and minorities have expanded beyond what previous generations would have considered imaginable. These changes did not occur because human beings suddenly became kinder. They emerged because institutions evolved, ideas spread, commerce rewarded cooperation and societies slowly learned from painful experience.

Progress, then, is neither dramatic nor inevitable.

It is cumulative.

It is fragile.

Above all, it is astonishingly easy to overlook.

Perhaps that is because the greatest transformations in history rarely announce themselves with fireworks. They arrive disguised as infrastructure, public health, education, regulation and scientific curiosity. They become ordinary so gradually that each generation mistakes them for the natural order of things.

And that may be the greatest illusion of all.

We inherit miracles.

Then we call them normal.

If there is one lesson history teaches with remarkable consistency, it is not that everything eventually works out.

History makes no such promise.

Empires collapse. Democracies weaken. Scientific knowledge can stagnate. Prosperous societies can become complacent. The Roman Empire did not survive. The Library of Alexandria was lost. Entire civilisations have disappeared, leaving behind little more than fragments of stone and unanswered questions. Progress, contrary to popular belief, is neither automatic nor irreversible. It requires institutions capable of sustaining it, citizens willing to defend it and generations prepared to improve rather than merely inherit what came before them.

Yet there is another pattern running quietly alongside those losses, one that receives far less attention because it unfolds too slowly to command headlines. Human beings possess an extraordinary ability to adapt to circumstances they once believed would destroy them. They reorganise economies after depressions, rebuild cities after wars, develop medicines after epidemics and rewrite institutions after political failure. Civilisation has never advanced because it escaped crisis. It has advanced because crisis repeatedly forced people to become more imaginative than they had previously been.

That distinction matters today because our own age is hardly short of reasons for anxiety. Artificial intelligence is developing at extraordinary speed, raising questions about employment, creativity and even consciousness. Climate change is reshaping ecosystems, coastlines and economies. Falling birth rates are transforming demographics across much of the developed world. Political polarisation has eroded trust in institutions that once appeared remarkably stable. None of these concerns should be dismissed. They deserve careful attention precisely because history shows that serious problems ignored early often become far more difficult to solve later.

But history also warns against a different mistake.

It warns against confusing uncertainty with inevitability.

Every generation believes its challenges are unprecedented because every generation experiences them without the benefit of hindsight. The citizens rebuilding London after the Great Fire did not know they were laying the foundations of one of the world’s great modern cities. The physicians who argued with Ignaz Semmelweis could not imagine that handwashing would become one of medicine’s most basic principles. The engineers preparing for the Y2K bug had no way of knowing that the decades following the new millennium would witness an even greater technological transformation than the one they feared might collapse.

Living through history has always been harder than reading it.

The historian enjoys a privilege unavailable to everyone else.

They already know how the story continued.

The rest of us never do.

Imagine, for a moment, someone opening a history book written a century from now. Somewhere within its pages will be a chapter describing our own age. It will speak of pandemics, artificial intelligence, climate change, geopolitical rivalry and economic uncertainty. It will catalogue our mistakes with a clarity that only hindsight permits. It will almost certainly describe opportunities we failed to recognise and warnings we ignored for too long.

But it will also describe discoveries that remain invisible to us today. It will recount institutions that have not yet been created, scientific breakthroughs that have not yet been imagined and solutions that, from our present perspective, appear almost impossible. Future historians will possess something we never can: the ending.

That, perhaps, is the greatest challenge of living in the present. We are asked to make judgments before the evidence is complete. We mistake unfinished chapters for completed books. We confuse today’s uncertainty with tomorrow’s destiny because uncertainty is all we have ever known firsthand.

This may explain why pessimism has always enjoyed an intellectual advantage over optimism. Predicting decline feels sophisticated because decline is easy to imagine. Improvement demands something far more difficult. It requires us to believe that millions of strangers — scientists, engineers, teachers, physicians, entrepreneurs, legislators and ordinary citizens — will continue solving problems we cannot yet foresee. Most of history’s greatest achievements were never accomplished by extraordinary individuals acting alone. They emerged from countless anonymous people making incremental improvements whose significance became visible only decades later.

We seldom remember those people.

History celebrates generals far more readily than sanitation engineers. It immortalises revolutions more often than vaccination campaigns. We build monuments to political leaders while overlooking the researchers, city planners, schoolteachers and public health officials whose quiet work lengthened life expectancy, reduced suffering and expanded opportunity for billions.

Yet civilisation rests far more heavily upon the second group than the first.

Perhaps that is why Deirdre McCloskey’s observation has lingered in my mind ever since I first encountered it. People do seem to enjoy hearing that the world is going to hell. Catastrophe flatters our instinct to believe we occupy an extraordinary moment in history. It gives today’s anxieties a sense of uniqueness.

History offers a gentler, and perhaps more demanding, perspective.

It reminds us that our fears are rarely unique. They are chapters in a much older story — a story in which each generation inherits problems it did not create, solves some of them, fails to solve others and leaves the unfinished work to those who follow.

That is not a story of inevitable progress.

Nor is it a story of inevitable decline.

It is a story of continuity.

Of imperfect human beings, armed with incomplete knowledge, repeatedly attempting to leave the world slightly better than they found it.

The people who rebuilt London after the Great Fire could not know that their city would become one of the world’s great capitals. They laid bricks because the alternative was to leave ruins. The physicians who slowly embraced antiseptic surgery could not foresee the modern hospital. They washed their hands because the evidence demanded it. The scientists who spent decades searching for vaccines did not know whose lives they would eventually save. They simply continued asking questions.

History, in the end, is rarely shaped by those who are most certain about the future.

It is shaped by those who continue building despite uncertainty.

Perhaps that is the most enduring lesson it has to offer.

Not optimism.

Not pessimism.

But humility — the humility to recognise that every generation before ours believed it understood where history was heading, and almost every generation was surprised by what came next.
