Can randomized experiments at the individual level help assess the persuasive effects of campaign tactics? To answer that question, we analyze a field experiment conducted during the 2008 presidential election in which 56,000 registered voters in Wisconsin were assigned to persuasive canvassing,...

Can independent groups change voters’ beliefs about an incumbent’s positions? Does reframing how candidates’ are perceived by changing beliefs about their positions influence actual voter choices? Past laboratory and observational research suggests that candidate reframing is difficult and...

Should political campaigns in close races communicate that they may win (over-confidence) or that they may lose (under-confidence)? In six studies (three survey experiments, two field experiments, and one archival study) we demonstrate the motivating power of under-confidence. While uncommitted...

We study an intervention designed to increase the effectiveness of parental involvement in their children’s education. Each week we sent brief individualized messages from teachers to the parents of high school students in a credit recovery program. This light-touch communication increased the...

We propose that people hold a belief in a favorable future (BFF), projecting that the future will change in ways advantageous to their current interests. People believe that their political views, entertainment preferences, and scientific beliefs will be more widely held by others in the future...

Behavioral science is increasingly being used to develop interventions to influence important behaviors throughout society. We explore three ways that time interacts with psychological processes to affect the impact of behavioral interventions. The first is how and when there would be a lag...

A field experiment examines how enrollment defaults affect the take-up and impact of an education technology (N=6,976). It shows that a standard (high-friction) opt-in process induces extremely low parent take-up (1%), while a simplified process yields higher take-up (11%), but both fail to...

It is common for organizations to offer awards to motivate individual behavior, yet few empirical studies evaluate their effectiveness in the field. We report a randomized field experiment (N = 15,329) that tests the impact of two common types of symbolic awards: pre-announced awards...

Ballot initiatives are consequential and common, with total spending on initiative campaigns in the US rivaling that of Presidential campaigns. Observational studies using regression approaches on observational data have alternately found that initiative campaign spending cannot affect...
