This is an interesting and important book. With the aid of computer modelling and some mathematics Robert Axelrod shows how co-operation can get started, what maintains it and what can stop it. Covering areas as diverse as WWI trench warfare, politics, biology and economics, Dr Axelrod shows how the same rules apply; all can be modelled as an iterated Prisoner's Dilemma. Axelrod shows how the most successful way of handling the dilemma is though co-operation: work to maximize both your score and your rival's and you will both to well; work to take advantage of your rivals and you'll do badly yourself. In summary:
Don't be envious
Don't be the first to defect
Reciprocate both cooperation and defection
Don't be too clever
This book should be compulsory reading for policy makers and politicians.
