Outcomes of Political Decision Making (2019)

in: Oxford Research Encyclopedia of Politics


"Decision outcomes" refers to mass political behavior as well as decisions by elites in the policy arena. Such outcomes are naturally the product of the decision-making process, a process that has been informed considerably by research in areas outside of political science. Political and policy processes are less defined by rational responses to incoming information than by pre-existing cognitive biases favoring narratives, stories, and symbols. Thus, to accurately understand decision outcomes requires an interdisciplinary approach, and, indeed, the discipline of political science has increasingly incorporated insights from psychology, social psychology, sociology, behavioral economics, and other social and natural sciences. Decision outcomes may reflect the true preferences of decision-makers, but behavior and outcomes have also been shown to change dramatically depending on who knows (or will know) the decision.Considering decision outcomes as the dependent variable, several factors have been identified that consistently and significantly shape outcomes in the political and policy worlds. Political outcomes, such as voting (by citizens and elites), are often explained by focusing on party ID or partisanship, and for good reason, but there are also instances in which decision outcomes are better encapsulated by more localized factors or influences. Policy outcomes, on the other hand, are less easily defined or predicted. Emotional testimonies and random fluctuations affect whether an issue is acted upon by a legislative body. Attention to social context and a concern for fairness is a primary driver of decision outcomes in social situations. In particular, leader–follower dynamics and group outcomes are significantly affected by the process in which decisions are made.
