Background Communicating official public health information about infectious diseases is complicated by the fact that individuals receive much of their information from their social contacts, either via interpersonal interaction or social media, which can be prone to bias and misconception. Objective This study aims to evaluate the effect of public health campaigns and the effect of socially communicated health information on learning about diseases simultaneously. Although extant literature addresses the effect of one source of information (official or social) or the other, it has not addressed the simultaneous interaction of official information (OI) and social information (SI) in an experimental setting. Methods We used a series of experiments that exposed participants to both OI and structured SI about the symptoms and spread of hepatitis C over a series of 10 rounds of computer-based interactions. Participants were randomly assigned to receive a high, low, or control intensity of OI and to receive accurate or inaccurate SI about the disease. Results A total of 195 participants consented to participate in the study. Of these respondents, 186 had complete responses across all ten experimental rounds, which corresponds to a 4.6% (9/195) nonresponse rate. The OI high intensity treatment increases learning over the control condition for all symptom and contagion questions when individuals have lower levels of baseline knowledge (all P values ≤.04). The accurate SI condition increased learning across experimental rounds over the inaccurate condition (all P values ≤.01). We find limited evidence of an interaction between official and SI about infectious diseases. Conclusions This project demonstrates that exposure to official public health information increases individuals’ knowledge of the spread and symptoms of a disease. Socially shared information also facilitates the learning of accurate and inaccurate information, though to a lesser extent than exposure to OI. Although the effect of OI persists, preliminary results suggest that it can be degraded by persistent contradictory SI over time.

Socio-Affective Traits Mediating Charitable Giving
This study explored the influence of various socio-affective factors on charitable giving, using an online task in which participants could choose to exert time and effort that was translated into monetary donations. Participants had the option of making Public Donations, Anonymous Donations, or No Donations. Moreover, some participants were given Social Information (SI) regarding the percentage of Public vs. Anonymous donations obtained in a pilot study. We found that the proportion of Public Donations increased with greater scores on the Narcissistic Entitlement & Exploitativeness scale (NPI EE), but only in the SI group. Conversely, the proportion of Anonymous Donations decreased with greater NPI EE scores, in the No Social Information group (NSI). In the absence of Social Information, Simulated Compassion scores (SCS), indicative of social approval seeking, decreased the proportion of No Donation decisions as well as the average amount donated. Finally, Social Information modulated the proportion of Public donations.

Can deliberation increase charitable giving when giving is impulsive (i.e., a one-time small gift in response to an immediate appeal)? We conduct two studies in Israel and Sweden to compare two forms of deliberation, unguided and guided, in their ability to decrease the singularity effect (i.e., giving more to one than many victims), often evident in impulsive giving. Under unguided deliberation, participants were instructed to simply think hard before making a donation decision whereas participants in the guided deliberation condition were asked to think how much different prespecified decision attributes should influence their decision. We find that both types of deliberation reduce the singularity effect, as people no longer value the single victim higher than the group of victims. Importantly, this is driven by donations being decreased under deliberation only to the single victim, but not the group of victims. Thus, deliberation affects donations negatively by overshadowing the affective response, especially in situations in which affect is greatest (i.e., to a single victim). Last, the results show that neither type of deliberation significantly reversed the singularity effect, as people did not help the group significantly more than the single victim. This means that deliberate thinking decreased the overall willingness to help, leading to a lower overall valuation of people in need.more » « less

Background Worldwide, nonpharmacologic interventions (NPIs) have been the main tool used to mitigate the COVID-19 pandemic. This includes social distancing measures (closing businesses, closing schools, and quarantining symptomatic persons) and contacttracing (tracking and following exposed individuals). While preliminary research across the globe has shown these policies to be effective, there is currently a lack of information on the effectiveness of NPIs in the United States. Objective The purpose of this study was to create a granular NPI data set at the county level and then analyze the relationship between NPI policies and changes in reported COVID-19 cases. Methods Using a standardized crowdsourcing methodology, we collected time-series data on 7 key NPIs for 1320 US counties. Results This open-source data set is the largest and most comprehensive collection of county NPI policy data and meets the need for higher-resolution COVID-19 policy data. Our analysis revealed a wide variation in county-level policies both within and among states (P<.001). We identified a correlation between workplace closures and lower growth rates of COVID-19 cases (P=.004). We found weak correlations between shelter-in-place enforcement and measures of Democratic local voter proportion (R=0.21) and elected leadership (R=0.22). Conclusions This study is the first large-scale NPI analysis at the county level demonstrating a correlation between NPIs and decreased rates of COVID-19. Future work using this data set will explore the relationship between county-level policies and COVID-19 transmission to optimize real-time policy formulation.more » « less

Modern kidney placement incorporates several intelligent recommendation systems which exhibit social discrimination due to biases inherited from training data. Although initial attempts were made in the literature to study algorithmic fairness in kidney placement, these methods replace true outcomes with surgeons’ decisions due to the long delays involved in recording such outcomes reliably. However, the replacement of true outcomes with surgeons’ decisions disregards expert stakeholders’ biases as well as social opinions of other stakeholders who do not possess medical expertise. This paper alleviates the latter concern and designs a novel fairness feedback survey to evaluate an acceptance rate predictor (ARP) that predicts a kidney’s acceptance rate in a given kidneymatch pair. The survey is launched on Prolific, a crowdsourcing platform, and public opinions are collected from 85 anonymous crowd participants. A novel social fairness preference learning algorithm is proposed based on minimizing social feedback regret computed using a novel logit-based fairness feedback model. The proposed model and learning algorithm are both validated using simulation experiments as well as Prolific data. Public preferences towards group fairness notions in the context of kidney placement have been estimated and discussed in detail. The specific ARP tested in the Prolific survey has been deemed fair by the participants.more » « less

This study examined the impact of Supplemental Instruction (SI) on student performance in introductory STEM courses at a Historically Black College or University (HBCU). Using a non-experimental, ex post facto design, academic outcomes from 105 courses and 2,829 student grades were analyzed over five semesters. While overall course performance scores did not significantly differ between SI and non-SI groups, SI-supported courses showed significantly higher frequencies of “B” and “C” grades and a greater proportion of passing rates. These findings suggest that SI may improve academic outcomes for students at risk of failure. Institutions seeking to reduce attrition in gateway STEM courses—especially among underrepresented students—should consider SI as a scalable, equity-driven academic support model.more » « less
