Dramatic changes in the way the public acquires information and formulates its attitudes have potentially altered the opinion and foreign policy relationship. While traditional approaches have treated public opinion on domestic and foreign matters as largely distinct, the culmination of a series of changes may eliminate the effective distinction between foreign and domestic policy, at least in terms of how the American political system operates. All the factors central to the opinion and foreign policy process, such as information acquisition, attitude formation, media effects, the effect of opinion on policy, and presidential leadership now appear to mirror the processes observed at the domestic level.
This analysis reviews historical trends in the literature on public opinion and foreign policy that has focused on the rationality of the public’s opinions, the structure of its attitudes, and its influence on foreign policymaking. The traditional Almond-Lippmann consensus portrayed an emotional public with unstructured attitudes and little influence on foreign policy; however, revisionist views have described a reasonable public with largely structured views on foreign policy that can, at times, constrain and even drive those policies. More recently, the rise of “intermestic” issues, contain both domestic and international elements, such as globalization, inequality, terrorism, immigration, and climate change, have interacted to transform the domestic and international context.
The bulk of this analysis highlights emerging new research directions that should be pursued in light of the changes. First, scholars should continue to evaluate the “who thinks what and why” questions with particular attention to differences between high- and low-information individuals, the effect of misinformation, and information sources. In doing so, research should build on research from non-American contexts that points to the important influences of societal and institutional factors. In addition to continued examination of traditional demographic factors such as partisanship and ideology, additional attention should turn to consider potential genetic and biological foundations of attitudes. Finally, researchers should continue to evaluate how the new media environment, including social media, affects how the public accesses information, how the media provides information, and how political elites attempt to shape both. Given these changes, scholars should consider whether it continues to make sense to treat public opinion dynamics regarding foreign policy as distinct from domestic policy and its implications.
