It is widely assumed that citizens are myopic, weighing policies’ short-term consequences more heavily than long-term outcomes. Yet no study of public opinion has directly examined whether or why the timing of future policy consequences shapes citizens’ policy attitudes. This article reports the results of an experiment designed to test for the presence and mechanisms of time-discounting in the mass public. The analysis yields evidence of significant discounting of delayed policy benefits and indicates that citizens’ policy bias towards the present derives in large part from uncertainty about the long term: uncertainty about both long-run processes of policy causation and long-term political commitments. There is, in contrast, little evidence that positive time-preferences (impatience) or consumption-smoothing are significant sources of myopic policy attitudes.
