From Oracles to Algorithms: A Golden Age of Prediction


Humans have always been fascinated by the future. Prior to the era of computers and data, we sought insights from the stars, dreams, and even animal behaviour. The tale of the Delphic Oracle is etched in this tapestry of human curiosity. A simple goat herder named Coretas reportedly stumbled upon a fissure in the earth, releasing ethereal vapours. Drawn by these mysterious emissions, he perceived glimpses of the future. This mystical spot soon became legendary. Word spread and people from distant lands journeyed here, drawn by the allure of prophecy. They came eager to hear the visions of the future, as interpreted by the chosen Pythia, a maiden who acted as the mouthpiece of Apollo. From mystical vapours to celestial patterns, humanity’s thirst for understanding tomorrow has perpetually pushed us to evolve our tools and methods, seeking ever-more sophisticated ways to peer into the future.

Throughout history, cultures around the globe have relied on a myriad of tools for forecasting the future. The Mayans, for instance, constructed elaborate calendars, meticulously tracking celestial bodies. Chinese sages consulted the I Ching, a revered text blending both philosophy and prediction. During the Middle Ages, figures like Nostradamus peered at the cosmos, firmly believing that the stars unveiled the secrets of events yet to unfold. Meanwhile, in their endless pursuit of the Philosopher’s Stone, alchemists hoped that their transformative experiments might also provide windows into future events. As the sands of time flowed, the rigours of science began to play an increasingly pivotal role in this age-old quest. Meteorologists harnessed accumulated data to forecast weather patterns, while demographers, attuned to shifts in population dynamics, used their insights to anticipate future demographic shifts.

Predictive analytics

Now, in this age, we’re navigating through a golden era of prediction. Computers, hailed as our contemporary oracles, delve into vast data lakes. With the aid of intricate algorithms and machine learning, they furnish insights about potential future events. Computers, hailed as our contemporary oracles, dive into vast data lakes — with less smoke and more code. Though technologically advanced, these modern tools have a mystique reminiscent of ancient methods. Indeed, their exceptional abilities often blur the lines between the arcane and the technological.

Even though the settings have changed—with glass skyscrapers replacing ancient temples—our innate desire to predict the future remains unwavering. We’ve shifted from seeking guidance from oracles to heeding the insights of modern-day experts: economists, scientists, and statisticians. The unpredictable nuances of geopolitics and the intricate web of global economies underscore the challenges of forecasting. Despite our technological advances, no tool or expert can perfectly predict outcomes, as emphasised by the renowned financier Peter Lynch: “You never can predict the economy. You can’t predict the stock market.”

It’s against this backdrop of prediction challenges that Philip Tetlock’s work shines prominently. Over decades, Tetlock undertook the meticulous task of analysing millions of predictions, unravelling the intricacies of human foresight. He identified the ‘superforecasters’, a rare group that consistently demonstrated superior predictive abilities.


Superforecasters stand apart from their peers, not simply through the accuracy of their predictions, but through their unique way of understanding and working with probabilities. Instead of confining themselves to somewhat nebulous terms like ‘likely’ or ‘certain’, they delve into a world of precision, where small differences matter. They employ an almost artistic attention to detail, carving out distinctions in probability estimates that most would overlook.

What’s noteworthy isn’t simply that they can perceive a difference between a 56% and a 57% probability, but the mindset this precision reflects. It speaks to a meticulousness, and diligence that’s often lacking in forecasting. This ability to finely calibrate their predictions sets them apart, transforming forecasting from a vague art into a refined science.

However, this is but one facet of their skills. Superforecasters also excel at dynamically updating their forecasts as new information comes to light, demonstrating humility in acknowledging and learning from their errors, and cultivating a probabilistic thinking mindset. Taken together, these skills contribute to their exceptional track record in the challenging realm of prediction.

In the aftermath of the Iraq war, where intelligence missteps around weapons of mass destruction became evident, the US intelligence community sought Tetlock’s expertise. His findings were detailed in his book, “Superforecasting: The Art and Science of Prediction”, serving as an invaluable guide for anyone looking to refine their forecasting skills.

Beyond the realm of politics and global affairs, the implications of Tetlock’s research are profound. His techniques offer practical applications in diverse arenas, from deciphering economic trends to pivotal personal decisions, such as evaluating career trajectories or the potential of a business venture.

Ethical & economical challenges

Yet, while Tetlock’s findings are ground-breaking, they’re not infallible. Even the best predictions are fraught with uncertainties. As we harness these insights, it’s vital to maintain a balanced approach, merging strong convictions with a healthy dose of caution.

By integrating Tetlock’s teachings, we can achieve a heightened awareness of our cognitive biases, enabling more informed decisions and, potentially, a brighter future.

While predictive tools offer remarkable insights, their overreliance introduces both ethical and economic challenges. Ethically, leaning too heavily on predictions can erode our adaptability and critical thinking, luring us into a false sense of security. Economically, this complacency can result in missed opportunities or misguided strategies. Just as the roll of a dice is inherently unpredictable, so too are complex systems like economies. They’re influenced by countless variables, making them vulnerable to unexpected twists and turns. Predictions, while valuable, are best used as guiding lights and not as absolute certainties. After all, at their core, they’re imbued with an intrinsic element of unpredictability.

In the realm of forecasting, we find that with great predictive power comes great responsibility — and the inevitable debate over who truly holds the crystal ball. The craft, while teeming with potential, is not without its boundaries and ethical dilemmas. Foretelling the future transcends the realms of science and art; it’s a weighty task that beckons us to navigate with zeal and caution. Here lies our unparalleled chance to influence humanity’s trajectory, yet we must remember to gracefully balance our acquired wisdom against the vast, ever-present unknowns.


As we conclude, we’re reminded of the timeless rhythm of humanity’s quest: from the ethereal mists of the Delphic Oracle to the digital pulses of algorithms. This cyclical endeavour to decipher tomorrow underscores our unyielding curiosity, a reflection of our innate need to foresee, understand, prepare, and connect with the uncertain embrace of the future.
