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.

17 Some investments may convert fungible tax dollars into forms of physical or human capital that are difficult for politicians to ‘raid’ later. Until the non-fungible capital has been fully created, however, the extracted tax dollars are still at risk of diversion, and that risk should be higher the longer it will take to produce the capital.

A comparison of the sample distributions of key demographic variables in our sample with the American National Election Studies 2008 Time Series Study reveals close comparability.

28 For instance, at the annual i of 2.9 per cent assumed by the Social Security Administration, B would have to be roughly 17 times higher in the 40-year than in the 5-year condition.

30 We might attempt to avoid the confound with periodic costs and benefits by informing subjects of the policy's total costs and benefits and holding these quantities (and thus the policy's NPV) constant across timing conditions. Subjects could be told, for instance, that they will pay total costs with ‘a present value of $14,095’ (the sum of the discounted costs described in the present study, in the forty-year condition, assuming i = 2.9 per cent) and, after five (or forty) years, will receive benefits with ‘a present value of $28,190’ (twice the discounted costs). This strategy would, however, leave subjects to guess about a critical temporal feature of the policy – the distribution of those costs over time. Would, for instance, the $14,095 be paid all at once in Year 1 or in equal instalments over five (or forty) years? It is unclear how subjects could engage in meaningful intertemporal reasoning in the absence of such information. Moreover, if a non-trivial proportion of subjects assumed a smooth distribution of costs over time (the likeliest profile), then the average perceived periodic costs of the policy tradeoff would still vary with the timing manipulation.
31 The three items were: ‘Now we would like to know what you think about the proposed reform to the Social Security system described in the presentation. Do you support or oppose the reform plan?’ ‘Now, please indicate how strongly you agree or disagree with the following statement. “I would be willing to pay the costs of the Social Security reform plan described in the presentation.” ’; ‘Now, please indicate how strongly you agree or disagree with the following statement. “It would be a good idea for the government to adopt the Social Security reform plan described in the presentation.” ’ Each item offered subjects four response levels. We code these items with equal intervals between responses.
32 All pairwise correlations (r) between index components exceed 0.80. The mean of the index is 0.40 and the standard deviation is 0.29.
33 In identifying these controls, we began by estimating a regression model of reform support that included all variables in our dataset potentially relevant to subjects’ orientation towards the reform. This included variables affecting individuals’ distributive stake in the reform (age, income, employment status, retired status, number of children); cognitive engagement with politics (political and economic knowledge, need for cognition, education); political orientations (egalitarianism, congressional and presidential approval, support for ‘less government’ and for Social Security spending, gender, race); economic perceptions (personal current, personal prospective, national current, national prospective); and interview start and completion dates. We employ as our standard controls those variables that were statistically significant in this larger model. All demographic variables were collected separately by KN.

38 In the curvilinear model, we centre age to reduce multicollinearity between age and its square.
39 In the context of this experiment, we note that older respondents should have more reason to care about the survival of the Social Security programme and may, thus, be more supportive of reform that would save it. This fact, however, should not affect age's interaction with the timing of policy effects, as older respondents (assuming they are less patient than younger respondents) should still have a stronger preference for the quicker delivery of benefits.
40 We report results for just one model specification for each impatience-proxy. The results are substantively unchanged across all alternative specifications described above; full results for all models are available in the on-line appendix.
41 The questions are based on the standard ANES economic perceptions battery. However, whereas in the ANES respondents are asked about ‘the next 12 months’, our item asks about the period ‘5 to 10 years from now’ in order to elicit judgments over a time horizon relevant to the reform issue.
42 The difference of means is 0.04 (p = 0.017).
43 Predicted values in this article are based on simulations produced using the clarify add-on to stata with variables other than those of interest set at their sample means. See Tomz, Wittenberg and King, ‘Clarify: Software for Interpreting and Presenting Statistical Results’.

46 As only twenty-five respondents gave the most trusting response on the ‘waste’ measure, we group together responses at the two most trusting levels of the measure.
47 Separate models were estimated for each variable and included both ‘main’ and interactive effects (Timing×control) for all controls. Note that age is included as both a linear and a quadratic term. For variables not described elsewhere in this article, descriptions are available in the on-line appendix.
48 See on-line appendix for these results.
49 We also tested for another potential explanation: that the moderation of timing effects by fiscal trust might have reflected a tendency by high-trusters not to scrutinize – and, thus, not to absorb – the temporal features of the reform described in the policy brief. We collected data on two indicators of attention to and reception of the information in the policy brief: length of time subjects spent reading the policy brief and, as discussed earlier, subjects’ timing perceptions. We find that, in the presence of appropriate controls, fiscal trust has no significant effect on either of these variables (analyses not reported), indicating that the trust effect does not operate through inattention to policy detail.

51 Our measure of time preference mentions includes all considerations suggestive of pure impatience, including references to the immediacy of the reforms costs; to the lower intrinsic value of future costs or benefits relative to present costs or benefits; and to concerns that benefits will arrive after the respondent has died. Consumption smoothing mentions consist of references to current and future expected economic circumstances, whether personal, group-specific (e.g., seniors), or national in scope; and to the greater ease of paying costs later than sooner. Uncertainty mentions include references to any form of uncertainty about whether the reform's benefits will emerge or be enjoyed by the respondent, including the possibility that the funds accumulated will be diverted or misspent by politicians; the past failure of politicians to responsibly manage the Social Security program; or uncertainty about Social Security's future financial difficulties.
52 The results are reported in the on-line appendix.
53 In all conditions, the reform's costs were described numerically.
54 This result also disposes of a further potential influence on intertemporal attitudes: inflation. With monetary payoffs, subjects might hypothetically perceive longer-delayed benefits to be smaller because of expected price increases over time. However, inflationary reasoning is inconsistent with the presence of a significantly stronger timing effect in the verbal condition, where respondents were given no monetary benefit value that could be adjusted for inflation. In addition, respondents in the numerical condition were told that all figures were expressed in current dollars.
55 Given a current US life expectancy of 78 years, we would not expect any age effect for subjects over about 40 years in the forty-year condition because age has virtually no effect on expected benefit-stream length within this subgroup: all subjects above 40 could expect personally to receive 0 years of benefits in the forty-year condition.
56 We add to our standard controls variables correlated with age that could influence reform support: party identification, political and economic knowledge, and support for Social Security spending.
