Much of international relations scholarship is based on generalizations about behavior. A certain level of abstraction is necessary to develop insight to avoid creating overly complex relationships that can never be understood. Explaining a particular event, however, will tend to call for a wider variety of factors than are represented in any given theory (which is a simplified model of reality). This is a point Waltz argues himself – even though he advocates abstracting at the international level to understand politics. Jervis holds that we must understand decisions at an individual level to explain dynamics in international politics. His abstractions are developed at this individual level, while he borrows concepts from psychology to develop insight about the factors that impact policymakers’ ability to understand and react appropriately to external pressures.
