Social corrections, wherein social media users correct one another, are an important mechanism for debunking online misinformation. But users who post misinformation only rarely engage with social corrections, instead typically choosing to ignore them. Here, we investigate how the social relationship between the corrector and corrected user affect the willingness to engage with corrective, debunking messages. We explore two key dimensions: (i) partisan agreement with, and (ii) social relationships between the user and the corrector. We conducted a randomized field experiment with Twitter users and a conceptual replication survey experiment with Amazon Mechanical Turk workers in which posts containing false news were corrected. We varied whether the corrector identified as a Democrat or Republican; and whether the corrector followed the user and liked three of their tweets the day before issuing the correction (creating a minimal social relationship). Surprisingly, we did not find evidence that shared partisanship increased a user’s probability of engaging with the correction. Conversely, forming a minimal social connection significantly increased engagement rate. A second survey experiment found that minimal social relationships foster a general norm of responding, such that people feel more obligated to respond – and think others expect them to respond more – to people who follow them, even outside the context of misinformation correction. These results emphasize social media’s ability to foster engagement with corrections via minimal social relationships, and have implications for effective, engaging fact-check delivery online.

Although they are only home to 16% of the global human population, high-income countries produce approximately one third of the world’s waste, the majority of which goes to landfills. To reduce pressure on landfills and natural systems, environmental messaging should focus on reducing consumption. Messages that signal social norms have the potential to influence people to reduce their consumption of comfort goods, such as straws, which are not a necessity for most people. We conducted a randomized field-experiment at a marine park in Portugal to test whether different normative messages reduced visitors’ paper straw use when compared to non-normative messages. We found that a message framed around a positive injunctive norm significantly reduced straw use compared to a non-normative message. We estimated that using the message at 17 park concession stands could keep over 27500 straws out of landfills annually and save the park money after two years.

Abstract Personal data increasingly serve as inputs to public goods. Like other types of contributions to public goods, personal data are likely to be underprovided. We investigate whether classical remedies to underprovision are also applicable to personal data and whether the privacy-sensitive nature of personal data must be additionally accounted for. In a randomized field experiment on a public online education platform, we prompt users to complete their profiles with personal information. Compared to a control message, we find that making public benefits salient increases the number of personal data contributions significantly. This effect is even stronger when additionally emphasizing privacy protection, especially for sensitive information. Our results further suggest that emphasis on both public benefits and privacy protection attracts personal data from a more diverse set of contributors.

Abstract We use a randomized field experiment to test the causal impact of short-term work experience on employment and school enrollment among disadvantaged, in-school youth in the Philippines. This experience leads to a 4.4 percentage point (79-percent) increase in employment 8 to 12 months later. While we find noaggregate increase in enrollment, we also do not find that the employment gains push youth out of school. Our results are most consistent with work experience serving as a signal of unobservable applicant quality, and these findings highlight the role of temporary work as a stepping-stone to employment for low-income youth.

We present the first field experiment on how organized interest groups’ television ads affect issue opinions. We randomized 31,404 voters to three weeks of interest group ads about either immigration or transgender nondiscrimination. We then randomly assigned voters to receive ostensibly unrelated surveys either while the ads aired, one day after they stopped, or three days afterwards. Voters recalled the ads, but three ads had a minimal influence on public opinion, whereas a fourth’s effects decayed within one day. However, voters remembered a fact from one ad. Our results suggest issue ads can affect public opinion but that not every ad persuades and that persuasive effects decay. Despite the vast sums spent on television ads, our results are the first field experiment on their persuasive power on issues, shedding light on the mechanisms underpinning—and limits on—both televised persuasion and interest group influence.
