Essence of Decision - Thesis

Thesis

When he first wrote the book, Allison contended that political science and the study of international relations were saturated with rational expectations theories inherited from the field of economics. Under such a view, the actions of states are analyzed by assuming that nations consider all options and act rationally to maximize their utility.

Allison attributes such viewpoints to the dominance of economists such as Milton Friedman, statesmen such as Robert McNamara and Henry Kissinger, disciplines such as game theory, and organizations such as the RAND Corporation. However, as he puts it:

It must be noted, however, that an imaginative analyst can construct an account of value-maximizing choice for any action or set of actions performed by a government.

Or, to put it bluntly, this approach (which Allison terms the "Rational Actor Model") violates the law of falsifiability. Also, Allison notes that "rational" analysts must ignore a lot of facts in order to make their analysis fit their models.

In response, Allison constructed three different ways (or "lenses") through which analysts can examine events: the "Rational Actor" model, the "Organizational Behavior" model, and the "Governmental Politics" model.

To illustrate the models, Allison poses the following three questions in each section:

1. Why did the Soviet Union decide to place offensive missiles in Cuba?
2. Why did the United States respond to the missile deployment with a blockade?
3. Why did the Soviet Union withdraw the missiles?
