Summary of: The Future of Everything: The Science of Prediction
By: David Orrell

The Evolution of Forecasting

Prediction and forecasting were majorly influenced by astrology until the scientific revolution which changed the perception of the universe as an ordered, structured place. With the establishment of the scientific method, it became clear that the universe could be explained through science. This shift was propelled by great scientists such as Tycho Brahe, Galileo, and Sir Isaac Newton. Even though forecasting has advanced significantly, the belief that the universe is ordered and structured still influences modern ways of thinking about forecasting.


Embark on a fascinating journey through ‘The Future of Everything: The Science of Prediction’ by David Orrell, as we explore the accuracy and limitations of forecasting in various fields such as weather, health, and economics. Delve into the history and evolution of forecasting, from the ancient Oracle at Delphi to the development of mathematical models. Understand the challenges scientists face in predicting complex systems and discover the factors that hinder their ability to provide precise predictions.

The Uncertainty of Forecasting

Today’s society takes modern forecasting for granted, from predicting the weather to medicine and the stock market. However, the accuracy of forecasting remains uncertain. Experts cannot predict the future accurately, and scientific advancements do not guarantee foolproof forecasting. An analysis of the history of forecasting reveals the inherent problems and challenges in predicting the future. This book delves into the complex world of forecasting, elucidating the uncertainties that plague it.

The History and Evolution of Future Prediction

From the Oracle of Delphi to Numerical Prediction, this book explores the history of future prediction. Ancient societies like the Greeks used various methods to foretell the future, with the Oracle at Delphi being one of the most renowned. Despite the Oracle’s prophecies being vague, many leaders based decisions on them. However, as Christianity gained strength, the Oracle’s influence dwindled. In addition to mystical sources, numbers played an essential role in predicting the future. Pythagoras believed that numbers were the key to understanding the universe, and his students elevated numerical prediction to new levels. Scholars, including Plato and Socrates, refined Pythagoras’ method, which led to the development of the modern scientific method. Today, social and scientific forecasting is still not entirely accurate, with predictions being as good as random guessing. However, these ancient methods remain relevant and serve as the basis of the modern scientific method for predicting the future.

The Limitations of Predictive Models

Despite centuries of experimentation, a complete understanding of the complex systems that make up our planet and universe is still out of reach. This leaves the question of whether we will ever accurately predict what will happen based on our knowledge of the smaller parts of the whole. The science of prediction has turned out to be conditional, varied, and extremely complicated. Even with advances in technology and statistical methods, predictive models are based on sets of equations that cannot precisely reflect the complex systems they attempt to measure. As a result, predictive models must be approached with caution.
