New insights from the science of science 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. 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.

Way back in 2012, I discovered Netgalley and requested a few books. But somehow, I lost track of my acceptances and eventually forgot all about Netgalley. My ARC of The Half-Life of Facts lay neglected, forgotten, and unread. The years went by, and eventually, I rediscovered Netgalley, only to find ...
I wish I thought that I would be able to remember everything I learned from this book, though Arbesman did give me an out by suggesting that the time has come to outsource our memories to the cloud because that's the best way of getting the latest information. But already I'm forgetting some of the ...
Easy to follow book on the changing nature of facts and how they help make our current foundation for science. He illustrates his points by many great vignettes such as why even today spinach is falsely believed to contain a lot of iron. That story alone makes the book worth a listen.
Repetitive, obvious, long-winded, and writing was dull.
