The Predictioneers GameDecision making is one of the last frontiers barely touched by science in day-to-day use. The Predictioneer's Game was written to help change that. The author is all for wisdom and "street smarts." But it is awfully hard to know who is wise and who has great intuition before decisions have to be made. It is much more helpful to have a proven method to connect the dots correctly beforehand. That is true whether addressing everyday life, business choices, or the biggest national security questions. The Predictioneer's Game is about learning to come up with reliable predictions to foresee and even engineer the future.
