System Effects [Hardcover]

Robert Jervis (Author)

Book Description

Publication Date: August 4, 1997

Argues that the foundations of many social science theories, especially those in political science, are faulty. Taking insights from complexity theory as a point of departure, this text observes that we live in a world where things are interconnected, where unintended consequences of our actions are unavoidable and unpredictable, and where the total effect of behaviour is not equal to the sum of individual actions. It draws on a range of human endeavours to illustrate the effect of these system effects. The book concludes by examining what it means to act in a system. It shows how political actors might modify their behaviour in anticipation of system effects, and it explores how systemic theories of political behaviour might account for the role of anticipation and strategy in political action.

Editorial Reviews

Review

"Drawing on a diverse body of scholarly research and a wealth of illuminating examples, Jervis shows that `system effects' are an important and often overlooked part of social and political life.... His insights will capture the imagination of those who puzzle over other social problems as well.... Viewed as a whole, System Effects offers a sobering and valuable moral." -- Steven M. Walt, The Atlantic Monthly

"System Effects presents a new way of looking at the international system as a network of inter-connections. The scholarship is sound, historically rich, and logically compelling." -- Glenn H. Snyder, Professor Emeritus, University of North Carolina at Chapel Hill

"There are few doubts that System Effects is an important and timely book, one that should be studied closely not only by Foreign Offices, but by all people faced with the task of making decisions while uncertain about the consequences of alternative actions--and such people make a very large readership indeed." -- Zygmunt Bauman, The Times Literary Supplement

4.0 out of 5 stars System Effects: complex, September 18, 2002

By

This review is from: System Effects (Paperback)

System Effects, by Robert Jervis, is an exploration of how the complex relationships between nations can generate or constrain action. Because each nation has its own goals and methods, it will try to seek the best situation. The problem is, because each nation has neighbors and opponents, it cannot always act precisely how it wants.

Jervis deals with three basic types of problem:
1) You cannot predict the total effect from individual effects. That is, although each policy you adopt might have a certain goal, some might backfire or feedback in unpredictable ways. An international example is the Trident missile: our goal was to get a more accurate second-strike capability to deter the Soviet hope for a first-strike success. However, their accuracy was so high that the Soviets perceived the Trident as a first strike weapon. Combined with the accuracy of the land-based missiles, it looked to some in the USSR that the US was planning for a first strike. This result is not predictable when you consider the land and sea based policies in isolation, or by simply assuming that your overall increase in accuracy has a deterrent effect. By making the Soviets more nervous, our policy may have increased the chances of war.

2) Your behavior depends in part on the behavior of others. One nation may seek peace, but it cannot disarm if its opponents pursue war. Alternatively, if your opponents follow a course of appeasement, you may continue in actions as an aggressor.

3) Your actions reshape the world in which you live. As you defeat one opponent, another may encroach on his territory and become a new threat. If you choose to disarm, others may perceive you as less threatening, and also disarm.

Jervis' account is detailed, but his writing style is a bit long-winded. I would have preferred more examples and less theory. Another problem is that the systems approach to international relations doesn't help you much: you can understand history, but because of the three effects he explains, you can't predict the future. Knowing about feedbacks and high order effects can make you cautious, but it can't inform you actions to a high degree.

I recommend this book for historians and strategists, but urge them to seek other sources for information on more concrete policy.

4.0 out of 5 stars Understanding International Systems, February 1, 2008

This review is from: System Effects (Paperback)

The essence of this book is a step-by-step guide on how to construct a framework to understand relations and transactions between nation states (under the rubric of `international relations'). Jervis conceptualizes the framework as an international system composed of individual units (nation states) whose transactions and relations with other nations, even if bilateral, will affect other nations that are not directly involved in the transactions. The behavior of a single nation (unit) thus can affect the entire system. Also the international system as a whole behaves differently and distinctly from its individual member states. Once this concept is described the remainder of the book is devoted in illustrating how the international system actually operates by breaking the system down into individual system components and describing how they function as illustrated by historical examples.

Jervis also demonstrates, unintentionally, how systems analysis can be used to understand the complex workings of international relations, although he does not use the term, "systems analysis." As this book demonstrates repeatedly, formulating a foreign policy relating to a specific issue concerning a specific nation should not be done in isolation, but should recognize the effect the policy will have on other nations and the international system as a whole. Jervis is not a believer in the discredited `domino theory' that led us into the Vietnam War. He simply accurately understands that nations do not and cannot exist in isolation. Events or changes to any one unit anywhere within the international system affect to a greater or lesser extent all other units in the system. The individual nations of the international system are also subject to a variety of internal and external factors that will affect their behavior and even their success or failure as a nations. These factors are as much a part of Jervis's international system as the nation states themselves and must be taken into account.

Now Jervis published this work in 1997 and did not address the current phenomenon of non-state actors (transnational terrorist groups, multi-national corporations etc.) routinely affecting the equilibrium of the international system and its member nations. Nor did he really consider his concept of an international system as the 21st Century phenomenon of globalization. Yet a little imagination on the part of the reader should make it clear that Jervis's system accurately describes the effects of globalization and that non-state actors can be easily factored into his international system. This book is not a particularly fun read, but it is an important one for any wishing to understand the complexities of globalization.
