The authors in this special issue of Presidential Studies Quarterly draw on a rich heritage of decision‐making analysis in the scholarly literature, much of it in the discipline of political science. Over the past several decades, scholars have approached the understanding of presidential decision making from a range of perspectives. The articles in this issue are rich in theory, strong in empirical evidence, and often prescriptive, explicitly or by implication. This introduction will briefly characterize some of the relevant research, contrast two decisions central to George W. Bush's presidency, and then introduce the articles and their contributions to our understanding of presidential decision making.
