This book describes tacit knowledge, what it is, how it used and its role in our current data driven world. It argues that fuzzy, hard-to describe information is greater and more, important than just hard facts.


What is tacit knowledge? It is what we might consider knowledge that is unable to be fully communicated; knowledge that we understand implicitly, but it is a bit hard to explain. For example, it is the kind of knowledge one needs to ride a bicycle, but that cannot be described precisely on paper in the way one might be able to explain how to cook a dish. Tacit knowledge is the least understood type of information and one of the most difficult to communicate. Yet there is more tacit knowledge in our lives than the specific facts one can find in a book, on the Internet or in the simple form of a fact. This book is designed to introduce the reader to the concept of tacit knowledge and how to recognize and use it. I
