Social Distancing During a Pandemic: The Role of Friends
Michael Bailey et al.
NBER Working Paper, December 2020
Abstract:
We explore how social network exposure to COVID-19 cases shapes individuals' social distancing behavior during the early months of the ongoing pandemic. We work with de-identified data from Facebook to show that U.S. users whose friends live in areas with worse coronavirus outbreaks reduce their mobility more than otherwise similar users whose friends live in areas with smaller outbreaks. The effects are quantitatively large: a one standard deviation increase in friend-exposure to COVID-19 cases early in the pandemic results in a 1.2 percentage point increase in the probability that an individual stays home on a given day. As the pandemic progresses, changes in friend-exposure drive changes in social distancing behavior. Given the evolving nature and geography of the pandemic -- and hence friend-exposure -- these results rule out many alternative explanations for the observed relationships. We also analyze data on public posts and membership in groups advocating to "reopen" the economy to show that our findings can be explained by friend-exposure raising awareness about the risks of the disease and inducing individuals to participate in mitigating public health behavior.
Social Hedonic Editing: People Prefer to Experience Events at the Same Time as Others

Social Psychological and Personality Science, forthcoming
Abstract:
Previous research testing the hedonic editing hypothesis examined preferences for the timing of events that happen to the self-asking, for example, whether people prefer to experience two positive or two negative events on the same or different day(s). Here, we examine preferences for the timing of events that happen to the self and to others - social hedonic editing. Across five studies (N = 2,522), we find people prefer to experience a positive or negative event on the same day that (vs. a different day than) another person experiences a similar positive or negative event. Studies 1 and 2 document this "preference for integration" in interpersonal (i.e., for the self and others) but not intrapersonal (i.e., for the self) contexts, Studies 3 and 4 suggest people prefer integration because it increases interpersonal connection, and Study 5 highlights a boundary condition. People do not prefer integration for very emotionally impactful events.
Temporal Associations Between Social Media Use and Depression
Brian Primack et al.
American Journal of Preventive Medicine, forthcoming
Methods: In 2018, participants aged 18-30 years were recruited in proportion to U.S. Census characteristics, including age, sex, race, education, household income, and geographic region. Participants self-reported social media use on the basis of a list of the top 10 social media networks, which represent >95% of social media use. Depression was assessed using the 9-Item Patient Health Questionnaire. A total of 9 relevant sociodemographic covariates were assessed. All measures were assessed at both baseline and 6-month follow-up.
Results: Among 990 participants who were not depressed at baseline, 95 (9.6%) developed depression by follow-up. In multivariable analyses conducted in 2020 that controlled for all covariates and included survey weights, there was a significant linear association (p<0.001) between baseline social media use and the development of depression for each level of social media use. Compared with those in the lowest quartile, participants in the highest quartile of baseline social media use had significantly increased odds of developing depression (AOR=2.77, 95% CI=1.38, 5.56). However, there was no association between the presence of baseline depression and increasing social media use at follow-up (OR=1.04, 95% CI=0.78, 1.38). Results were robust to all sensitivity analyses.
Trust Does Beget Trustworthiness and Also Begets Trust in Others
Marc Cohen & Mathew Isaac
Social Psychology Quarterly, forthcoming
Abstract:
Social scientists widely believe that trust begets trustworthiness, meaning that persons reward actions that they view as expressing trust. But evidence from the trust game (also known as the investment game) - introduced by Berg, Dickhaut, and McCabe and frequently used to test this relationship - is surprisingly inconclusive. The present article therefore reexamines this hypothesis (Experiment 1), using the trust game but incorporating mediation analysis and distinguishing between trust and distrust effects. The trust game has been used to study the effects of trust within a relationship: when A trusts B, does this affect B's behavior toward A? This research (in Experiment 2) extends the question: when A trusts B, is B more likely to trust another player C in a second (unrelated) game? If so, then trust relationships have a transitive structure. Taken together, findings from these experiments show that trust begets trustworthiness and also trust in others.
Differences in cortisol following cooperative and competitive work-related tasks with same-sex versus opposite-sex partners
Leah Sheppard et al.
Psychoneuroendocrinology, forthcoming
Abstract:
Previous research indicates that circulating concentrations of cortisol increase during interactions with opposite-sex others in the presence of mating cues. However, it remains unknown whether this phenomenon extends to work-related tasks in which explicit mating cues are absent. In a series of two studies, we assessed women's and men's salivary cortisol concentrations before and after completing cooperative brainstorming (Study 1) and competitive negotiation (Study 2) tasks wherein they worked with same- or opposite-sex partners. Both studies revealed significant participant sex by partner sex interactions. Specifically, male participants demonstrated significantly larger increases in salivary cortisol concentrations when working alongside opposite-sex as opposed to same-sex partners on a cooperative task. In contrast, female participants demonstrated significantly larger increases in salivary cortisol concentrations when working with opposite-sex as opposed to same-sex partners on a competitive task. Opposite-sex teams also produced fewer novel ideas relative to same-sex teams on the cooperative brainstorming task; however, differences in cortisol did not account for this effect. Our research extends previous research demonstrating elevated cortisol during opposite-sex interactions in the presence of explicit mating cues to a work-related context that is divorced from mating cues.
Physical Attractiveness, Halo Effects, and Social Joining
Carl Palmer & Rolfe Daus Peterson
Social Science Quarterly, forthcoming
Methods: Utilizing the Wisconsin Longitudinal Study and an original survey experiment, we find that individuals who are rated as more attractive are consistently more likely to participate in organizations, particularly early in adult life. These effects persist when controlling for socioeconomic variables like income and education.
Results: Our experimental results bolster these findings, showing that more attractive individuals are more likely to be invited to join both organizations and informal gatherings.
