We've added a new book to our 'Book Club'. What is a 'Black Swan'?
In Europe all anyone had ever seen were white swans; indeed, "all swans are white" had long been used as the standard example of a scientific truth. So what was the chance of seeing a black one? Impossible to calculate.
Or at least they were until 1697, when explorers found Cygnus atratus in Australia. - Chris Anderson, Editor-in-Chief of 'Wired' Magazine
We put too much weight on being able to predict the future by what we have already experienced, or what has worked for others. 'Black Swan' events are the completely unfathomable that no amount of planning will prepare for, and often the most important events.
Success becomes about what we do not know.
