Temná data - Proč záleží na tom, co nevíme – Hand David J. (2023)

In the era of big data, it is easy to believe that we have all the information needed to make sound decisions. In reality, the data available to us are never complete and usually represent only the tip of the iceberg. Just as most of the universe consists of dark matter that is invisible yet present, the information universe is full of dark data that we overlook at our own expense. In this Czech-language book, data expert David Hand takes readers on a fascinating journey through the world of data we cannot see. He examines the many ways missing data can blind us to reality and lead to mistaken, dangerous or even catastrophic conclusions and actions. Drawing on numerous real cases, from the destruction of the Challenger space shuttle to complex financial machinations, Hand presents a practical taxonomy of different kinds of dark data and the situations in which they arise, helping readers learn to recognise and control them. The book shows not only how to guard against the problems created by what we do not know, but also how to use dark data to our advantage by better understanding the decisions we make. Today, everyone makes decisions based on data, and this book shows how to avoid making the wrong ones whenever possible.
