Foresight is an important tool in policy analysis, and encompasses a wide spectrum of methods and approaches. This handbook tackles the major questions that have to be considered in embarking upon knowledge society foresight. It does so largely in a question-and-answer format.The handbook is neither an essay on knowledge society foresight nor is it simply a toolkit of ways to think about long-term futures. It is a guide to foresight and to making decisions to undertake activity in the field. It is illustrated with some examples drawn from relevant activities around the world, while a series of annexes provide more discussion, essays and resource materials for those wishing to pursue matters more deeply.
