The Use of Inter-Nation Simulation as a Research Tool.

After four years of using simulation in the study of international relations, the authors have found it to be a potentially powerful research and teaching device. In this report they examine advantages, such as the ability it gives the researcher to manipulate experimental variables, and disadvantages associated specifically with the use of simulation in political science. They contend that the use of simulation is often prematurely rejected when refinement on the basis of legitimate criticism is what is needed. Among the research strategies available for testing and revising simulation models is face validity evaluation which the authors use in their revision of the Inter-National Simulation (INS) to exemplify such refinement. In INS greater realism and sophistication results when a military advisor is included in the national decision making organization, when geographic dimensions and historical background are increased, and when internal revolution is introduced. A number of practical considerations associated with simulation in conducting a research project are also included in the paper--all in the hope of promoting the use of simulation as a research technique in political science.
