Before the Algorithm, There Was the Oracle
We face a volatile, uncertain, complex and ambiguous world. What can we learn about facing these challenges from ancient Classical beliefs?
This is the first in a new series, From Oracles to Algorithms—an exploration of uncertainty, prediction, foresight, and statistics. We’ll trace how humans have wrestled with the unknowable future, from the cryptic visions of ancient seers to today’s machine-learning models built on statistical theory. Across time, we’ve sought patterns in chaos, meaning in randomness, and control in the face of danger. This series will examine the evolving tools, beliefs, and breakthroughs that shape how we try to see what comes next, and what that says about us.
The future can be confusing, foggy, unknown, scary, dangerous, and sometimes exciting, full of possibility and opportunity. People tend not to like uncertainty (some tolerate it better than others), and we do all number of things to reduce it, either by controlling our world, or attempting to understand it better.
One of the most important, and most difficult, aspects of leadership is strategic foresight: the process of thinking about what’s happening now, forecasting the future, and guiding your people toward a desirable outcome, and away from the undesired ones.
To help us solve the problem of foresight, we make use of algorithms of prediction. We simulate tomorrow with spreadsheets, bet billions on models, and consult analytics dashboards like a digital Delphi. But we did not invent thinking about the future. We inherited it from those who feared it, worshipped it, defied it, and, most often, misunderstood it entirely.
The ancient world had a few solutions to the prediction problem. Before predictive analytics, before the Monte Carlo simulation, before suited consultants brought their PowerPoint decks, soothsayers of old brought sacred scrolls, and entrails, read the flightpath of birds, experienced sulphurous visions, and consulted veiled women in smoke-filled temples, the only who were permitted to speak truths too dangerous for anyone else to say.
Cassandra: The Curse of Being Right
Cassandra was the original whistleblower. A Trojan princess, gifted by Apollo with the ability to flawlessly see the truth, only to be destroyed by the curse of never being believed. The ancient Chicken Little (“the sky is falling!”) It's not hard to see why her story still echoes in our age of ignored climate scientists and economists waving red flags warning of collapse in the face of bullish markets.
Cassandra foresaw the fall of Troy, begged her people not to trust the Greeks and their gifted horse full of enemies. She was right, but she was dismissed and so the city burned. Cassandra is the patron saint of whistleblowers, black swan spotters, and all those laughed out of the room for stating the obvious too early. Her curse wasn’t being wrong, it was being right but not being able to convince the world of the impending catastrophe.
There are two lessons we can learn from Cassandra. First, when it comes to decision-making, persuasion and perception is just as important as predictive accuracy. There’s no point being right if people don’t understand you, trust you, or see how to make use of your insights. Second, we suffer from biases, whether cognitive or emotional, that sometimes make certain truths unpalatable. We discard the prediction, not because it’s flawed, but because we don’t like what it tells us might happen, and what that means for us if it comes true. This is a serious mistake. Reality is coming, whether we like it or not, and ignoring wise counsel because of unfounded faith in our own destiny is the height of hubris.
Cassandra’s curse lives on in boardrooms, war-rooms, and every “I told you so” that follows a catastrophe.
Tiresias: The Blind Seer Who Saw In Paradoxes
Tiresias, the Theban prophet, lived as both man and woman (that’s a whole other story), saw with blindness what the sighted could not, and was punished for speaking truth to gods. He was the Greek prototype of paradox: foresight through limitation, wisdom through suffering, vision through obscurity. In our age of data, Tiresias reminds us quantity is not clarity. You can stare at a thousand metrics and still see nothing.
Blinded for providing the goddess Hera and answer which displeased her, like Cassandra, Tiresias learned that clear vision is sometimes unwelcome by those with power. But also, having lived both male and female lives, Tiresias is a symbol of the importance of justice in wisdom. Good decisions cannot be made without understanding all sides, knowing the pros-and-cons, and managing the tension between opposites.
Prometheus: The Rebel Who Stole Fire (and Forecasting) From The Gods
Prometheus didn’t just gift fire to the world, he gifted forethought. Literally. In Greek, ‘Prometheus’ means “forethought.” He was punished, eternally, for enabling humans to plan beyond the present, and for giving us the technology to spark our creative abilities.
This titan saw a future for humans where they were more than animals reacting to instinct. He gave us the symbolic spark of predictive reasoning, and for his trouble, he was nailed to a rock while an eagle feasted daily on his liver.
In our modern Promethean moment, where tech titans reach beyond limits, his tale still sings: Foresight is divine power. And Prometheus didn’t just hand over fire. He paid for it, for eternity. As Nassim Taleb would say, that’s real skin in the game. He gave humans foresight and took the consequences personally. Compare that to modern forecasters whose failed models blow up pension funds or economies and walk away with bonuses and tenure.
Seeing the future is a dangerous game, and those who do will often be held accountable for it.
Pythia and the Oracle of Delphi
The classic image of the prophet, picture this: a woman seated atop a mountain, out of her mind on sulphuric volcano fumes, babbling riddles to kings and conquerors who traveled for weeks just to hear her. This was Pythia, the voice of Apollo at Delphi, a source of ambiguous wisdom, and patron saint of every consultant who has ever said, “It depends.”
One of the fundamental properties of foresight is it is ambiguous. The signs we see today which point to tomorrow, don’t just lead to one tomorrow. They could lead us to many different tomorrows. And even the best predictions always leave room for error.
When Croesus of Lydia asked the Oracle if he should wage war on Persia, she answered, “If you do, a great empire will fall.” She was right. But it was not the empire of Persia that fell, but his own instead.
In a world obsessed with precision, the oracles of Delphi remind us that prediction is not really an answer, it’s still a question: cryptic, slippery, and always conditional. Only fools have certainty. Rather than attempting to precisely predict outcomes, sometimes it’s better to cover many different possibilities. Planning not just for what might go right, but defending against what might go wrong as well.
Roman Augurs: Reading the Sky for Strategy
The Romans formalised fortune-telling into statecraft. Augurs interpreted omens from the flight of birds, “auspices” were literally bird watchers. Want to go to war? Ask the birds. Need a new governor? Consult the chicken entrails.
To our scientific minds, this kind of superstition could be seen as ridiculous. But ask yourself this: are our rituals any more rational? We stare at market indicators, poll numbers, and predictive models with equal superstition. Attempting to spot patterns in the scatterplot, the rituals persist. What moves will the Reserve Bank make? Consult the futures market for a clue.
The Roman augur watching birds flap left instead of right was less sophisticated but no different in intention to a risk analyst simulating returns on an Excel sheet. Where fate or chance is at play we look for ways to tip the odds in our favour, to make the entirely unknowable at least partially expected.
But the map is not the territory, and the spreadsheet is not the sky. Forecasting the future by learning from the past, observing the present and projecting the future is a method for reducing uncertainty. But not necessarily for winning. Reading the entrails or drawing lines on the stock chart only works if the gods are playing fair, and they rarely do.
Complexity, Chaos, and the Gods of Uncertainty
The ancients did not believe the future could be controlled, far from it. Fate was the domain of the gods. Instead, they believed it could be glimpsed through fog, fire, or metaphor. They knew the world was a tapestry of forces too vast to reduce to linear cause and effect. In other words, they intuited complexity science long before it had a name.
We now call it emergence and feedback loops. But they called it fate and divine will. They built myths to house their models. We build models and forget they are constructions, stories we tell ourselves to comfort our anxiety about the future.
The ancients feared hubris, not uncertainty. They knew the future punishes smug certainty. Prediction without humility is a recipe for tragedy of the Greek kind.
These stories endure because they speak to something AI can’t compute: the emotional weight of the unknown, when clarity never comes, or only comes when it’s too late to change. They speak of the loneliness of seeing further than others, the madness of knowing what must be done, only to be ignored punished or held responsible.
The ancients were not ignorant. They were brutally honest about what it means to want to know the future: it isolates, it tempts, it punishes, and on rare occasions it saves.
They remind us that prediction is not just a tool. It is a burden, a gamble, a moral challenge. Too often we expect and demand the world to conform to our models, rather than accepting fate, updating the prediction, and swallowing our pride.
