Why Predicting the Future is Hard (But Not Impossible)
"Prediction is very difficult," goes the famous Danish proverb, "especially about the future." This wry observation captures a fundamental truth: the unknown future both fascinates and frustrates us. Yet, despite its inherent difficulty, predicting the future isn't just the realm of crystal balls and tarot cards – it's a rigorous scientific pursuit with profound implications.
Philosopher Oliver Beige argues that the ability to make accurate, testable predictions about the future is the defining hallmark of true science, setting it apart from merely describing the past or present ("the art of predicting the past") 1 .
The scientific method is fundamentally iterative and cyclical 8 . Scientists observe, hypothesize, predict, test, and then analyze & revise their understanding based on results.
Unlike the past or present, which leave evidence (however incomplete), the future is equally unknown to everyone. This inherent uncertainty makes prediction inherently challenging but also the ultimate test of scientific understanding 1 .
Type | Cause | Reducible? | Example | Common Approach |
---|---|---|---|---|
Aleatory | Inherent randomness/stochasticity in the system | No (can characterize) | Weather on a specific day next month | Probability distributions, Statistics |
Epistemic | Lack of knowledge, imperfect models, insufficient data | Yes (with research) | Exact future sea-level rise by 2100 | Improved models, Data collection |
Deep Uncertainty | Disagreement on models/probabilities/values; multiple futures | Very Difficult | Geopolitical landscape in 2050 | Scenario planning, Robust decision making |
VUCA (Environment) | Volatility, Uncertainty, Complexity, Ambiguity interacting | Partially | Impact of disruptive AI on labor markets | Adaptive strategies, Foresight tools |
An acronym capturing interrelated challenges:
Modern global challenges (pandemics, climate disruption, tech disruption) often exist in VUCA environments, making prediction exceptionally difficult .
How can we predict societal responses to future technologies before they are fully deployed? The groundbreaking "Moral Machine" experiment provides a fascinating example 3 .
To understand global public preferences regarding the ethical decisions self-driving cars (AVs) might have to make in unavoidable accident scenarios.
Researchers created millions of hypothetical unavoidable accident scenarios with various variables.
A multilingual online platform ("Moral Machine") was launched.
Participants were shown two different accident outcomes and forced to choose which one they found less objectionable.
The experiment gathered over 40 million decisions from millions of participants in over 200 countries 3 .
Example of an autonomous vehicle scenario
Preference | Strength |
---|---|
Humans over Animals | Very Strong |
More Lives over Fewer Lives | Very Strong |
Younger over Older | Strong |
Law-Abiding over Jaywalking | Moderate |
Provided the first large-scale, quantitative map of global public opinion on AV ethical dilemmas.
Results directly informed discussions on AI ethics guidelines 3 .
Pioneered using controlled experiments to simulate interactions with future technologies.
Uses mathematical equations describing physical processes to calculate future system states. Breaks complex systems into manageable parts solved by powerful computers.
Example: Weather forecasting, climate modeling 9 .
Combines human judgment with AI's ability to process vast data and identify complex patterns. Improves accuracy over either alone.
Example: SAGE Project: Forecasting geopolitical/economic events 5 .
Develops multiple, internally consistent, plausible narratives about the future. Focuses on exploring divergent possibilities.
Example: Planning for climate change adaptation .
Identifies strategies that perform "well enough" across a wide range of plausible future scenarios.
Example: Water resource management under climate uncertainty .
Case Study: The Pacific Walrus. Scientific predictions often clash with policy and legal timeframes. The U.S. Endangered Species Act protects species threatened with extinction "in the foreseeable future." However, defining this timeframe is contentious 4 .
Predicting the future remains profoundly difficult. The sheer complexity of interacting systems, the role of human agency, and the inevitability of unforeseen events guarantee that surprise will always be a feature of our existence.
Yet, science has moved far beyond mere guesswork. By rigorously testing models against reality, quantifying uncertainty, simulating plausible futures, and combining human and artificial intelligence, we are developing a richer, more nuanced understanding of what might lie ahead.
Not clairvoyance, but preparedness – building the knowledge, tools, and resilience needed to navigate the unpredictable currents of tomorrow.
