DARK DATA - DAVID J HAND GEBUNDEN

In the era of big data  it is easy to imagine that we have all the information we need to make
good decisions. But in fact the data we have are never complete  and may be only the tip of the
iceberg. Just as much of the universe is composed of dark matter  invisible to us but
nonetheless present  the universe of information is full of dark data that we overlook at our
peril. In Dark Data  data expert David Hand takes us on a fascinating and enlightening journey
into the world of the data we don't see. Dark Data explores the many ways in which we can be
blind to missing data and how that can lead us to conclusions and actions that are mistaken 
dangerous  or even disastrous. Examining a wealth of real-life examples  from the Challenger
shuttle explosion to complex financial frauds  Hand gives us a practical taxonomy of the types
of dark data that exist and the situations in which they can arise  so that we can learn to
recognize and control for them. In doing so  he teaches us not only to be alert to the problems
presented by the things we don't know  but also shows how dark data can be used to our
advantage  leading to greater understanding and better decisions.
