Small variations in them can influence the type of democracy that develops. Political science is essential to the study of why and how this happens: hundreds of political scientists develop and test theories about the consequences of electoral rules and regulations for party systems, representation, governance, and other aspects of democratic politics. In addition, political scientists have worked as electoral system engineers, educating and advising policy makers around the world by authoring reports, delivering presentations at global and regional meetings, traveling on consulting missions, and training democracy promotion officers. By sharing scientific knowledge about the consequences of electoral rules and global trends in electoral reform, political scientists make their work relevant to the world. The report shows how political scientists have contributed to the world of electoral systems as scientists and as engineers. Its separate essays and appendices take stock of their work. Its principal findings include the following. n A great deal of recent
