Poliheuristic (PH) theory models foreign policy decisions using a two-stage process. The first step eliminates alternatives on the basis of a simplifying heuristic. The second step involves a selection from among the remaining alternatives and can employ a more rational and compensatory means of processing information. The PH model posits that strategic/realist factors are more important in the second step of the process. The model is tested for the years 1918 to 1994, using crisis actors from the International Crisis Behavior data set. Results show that domestic political loss has a negative impact on the use of violence in response to a crisis trigger. Contiguity, joint democracy, and trigger are also significant in the expected directions. Relative capabilities have a positive impact, and enduring rivals do not appear more likely to use violence against each other as a first response in a crisis.A key divergence in the empirical study of international relations has been that between cognitive and systemic/rational approaches (Hagan 2001). All too often, each school has considered the other as overly deterministic or ad hoc. Jerel Rosati (2001) takes this discussion a step further because he calls for a merger between rational and cognitive approaches. Like Hagan (2001), Rosati asserts that scholars should not treat the state as a "black box." In other words, we need to explore state actions as a function of the human cognition of their leaders. By dismissing the human cognition component of decisions, we may be discarding important information. Focusing on the rational model alone might give only information about outcomes and preferences. Looking at cognitive issues can tell us about processes and beliefs as well as where preferences come from and how they are established. Rosati suggests that the
