About this book

Facts change all the time. Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that Pluto was a planet. For decades, we were convinced that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing. But it turns out there’s an order to the state of knowledge, an explanation for how we know what we know.

Samuel Arbesman is an expert in the field of scientometrics – literally the science of science. Knowl­edge in most fields evolves systematically and predict­ably, and this evolution unfolds in a fascinating way that can have a powerful impact on our lives. Doctors with a rough idea of when their knowl­edge is likely to expire can be better equipped to keep up with the latest research. Companies and govern­ments that understand how long new discoveries take to develop can improve decisions about allocating resources. And by tracing how and when language changes, each of us can better bridge gen­erational gaps in slang and dialect. Just as we know that a chunk of uranium can break down in a measurable amount of time – a radioactive half-life – so too any given field’s change in knowledge can be measured concretely. We can know when facts in aggregate are obsolete, the rate at which new facts are created, and even how facts spread.
 
In The Half-life of Facts, Arbesman takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries. He shows that much of what we know consists of “mesofacts” – facts that change at a middle timescale, often over a single human lifetime. Throughout, he of­fers intriguing examples about the face of knowledge: what English majors can learn from a statistical analysis of The Canterbury Tales, why it’s so hard to measure a mountain, and why so many parents still tell kids to eat their spinach because it’s rich in iron. The Half-life of Facts is a riveting journey into the counterintuitive fabric of knowledge. It can help us find new ways to measure the world while accepting the limits of how much we can know with certainty.

Media reviews

"Delightfully nerdy."
Wall Street Journal

“How many chromosomes do we have? How high is Mount Everest? Is spinach as good for you as Popeye thought – and what scientific blunder led him to think so in the first place? The Half-life of Facts is fun and fascinating, filled with wide-ranging stories and subtle insights about how facts are born, dance their dance, and die. In today’s world, where knowledge often changes faster than we do, Samuel Arbesman’s new book is essential reading.”
- Steven Strogatz, professor of mathematics, Cornell University, and author of The Joy of X
 
“What does it mean to live in a world drowning in facts? Consider The Half-life of Facts the new go-to book on the evolution of science and technology.”
- Tyler Cowen, professor of economics, George Mason University, and author of An Economist Gets Lunch
 
The Half-life of Facts is a rollicking intellectual journey. Samuel Arbesman shares his extensive knowledge with infectious enthusiasm and entertaining prose. Even if the facts around us are ever changing, the lessons and fun in this book will have a very long half-life!”
- Michael J. Mauboussin, chief investment strategist, Legg Mason Capital Management, and author of The Success Equation
 
The Half-life of Facts teaches you that it is possible, in fact, to drink from a fire­hose. Samuel Arbesman, an extremely creative scientist and storyteller, explores the paradox that knowledge is tentative in particularly consistent ways. In his ca­pable hands, we learn about everything from how medieval manuscripts resemble genetic code to what bacteria and computer chips have in common. This book un­ravels the mystery of how we come to know the truth – and how long we can be certain about it.”
- Nicholas A. Christakis, MD, PhD, coauthor of Connected
