Virtual lab coats: The effects of verified source information on social media post credibility.

Social media platform's lack of control over its content made way to the fundamental problem of misinformation. As users struggle with determining the truth, social media platforms should strive to empower users to make more accurate credibility judgements. A good starting point is a more accurate perception of the credibility of the message's source. Two pre-registered online experiments (N = 525;N = 590) were conducted to investigate how verified source information affects perceptions of Tweets (study 1) and generic social media posts (study 2). In both studies, participants reviewed posts by an unknown author and rated source and message credibility, as well as likelihood of sharing. Posts varied by the information provided about the account holder: (1) none, (2) the popular method of verified source identity, or (3) verified credential of the account holder (e.g., employer, role), a novel approach. The credential was either relevant to the content of the post or not. Study 1 presented the credential as a badge, whereas study 2 included the credential as both a badge and a signature. During an initial intuitive response, the effects of these cues were generally unpredictable. Yet, after explanation how to interpret the different source cues, two prevalent reasoning errors surfaced. First, participants conflated source authenticity and message credibility. Second, messages from sources with a verified credential were perceived as more credible, regardless of whether this credential was context relevant (i.e., virtual lab coat effect). These reasoning errors are particularly concerning in the context of misinformation. In sum, credential verification as tested in this paper seems ineffective in empowering users to make more accurate credibility judgements. Yet, future research could investigate alternative implementations of this promising technology.

Patient-Reported Dry Eye Treatment and Burden of Care.

OBJECTIVES: Dry eye is a common condition that can decrease the quality of life. This survey-based study of persons with dry eye investigated self-reported treatments (initial, current), out-of-pocket expenses, time spent on self-management, sources of care, and sources of information about their condition. METHODS: Online dry eye newsletters and support groups were emailed a link to an electronic survey asking members to participate. Survey respondents were not required to answer every question. RESULTS: In total, 639 persons with self-reported dry eye responded (86% women, 14% men [n=623]; mean ± SD age, 55 ± 14 years [n=595]). Artificial tears were the most reported intervention (76% initially, 71% currently). The median (interquartile range) out-of-pocket treatment cost annually was $500 ($200-$1,320 [n=506]). In addition, 55% (n=544) estimated 5 to 20 min daily on self-management; 22% spent an hour or more. Ophthalmologists provided most dry eye care (67%, n=520). Only 48% (n=524) reported that their primary source of dry eye information came from their eye care clinician. CONCLUSIONS: Artificial tears are the primary treatment for dry eye. Ophthalmologists provide most dry eye care, but half of patients report that their eye care provider is not their primary source of information. Almost one fourth of patients spend an hour or more daily on treatments.

Users choose to engage with more partisan news than they are exposed to on Google Search.

If popular online platforms systematically expose their users to partisan and unreliable news, they could potentially contribute to societal issues such as rising political polarization1,2. This concern is central to the 'echo chamber'3-5 and 'filter bubble'6,7 debates, which critique the roles that user choice and algorithmic curation play in guiding users to different online information sources8-10. These roles can be measured as exposure, defined as the URLs shown to users by online platforms, and engagement, defined as the URLs selected by users. However, owing to the challenges of obtaining ecologically valid exposure data-what real users were shown during their typical platform use-research in this vein typically relies on engagement data4,8,11-16 or estimates of hypothetical exposure17-23. Studies involving ecological exposure have therefore been rare, and largely limited to social media platforms7,24, leaving open questions about web search engines. To address these gaps, we conducted a two-wave study pairing surveys with ecologically valid measures of both exposure and engagement on Google Search during the 2018 and 2020 US elections. In both waves, we found more identity-congruent and unreliable news sources in participants' engagement choices, both within Google Search and overall, than they were exposed to in their Google Search results. These results indicate that exposure to and engagement with partisan or unreliable news on Google Search are driven not primarily by algorithmic curation but by users' own choices.

Trusted Sources of Information and COVID-19 Vaccine Uptake in a Sample of Latinx Sexual and Gender Minorities in South Florida.

OBJECTIVE: To examine factors associated with COVID-19 vaccine uptake in a sample of Latino/a/x sexual and/or gender minority (SGM) individuals in South Florida. DESIGN: Data were collected via an online survey from March 2021 to August 2022, as part of the Community Engagement Alliance Against COVID-19 Disparities. A multivariate regression analysis was fit using completion of a COVID-19 vaccine regimen as the outcome. Key covariates included trusted sources of information (eg, doctor, media), COVID-19-related challenges (eg, accessing medication, transportation), and dominant wave of SARS-CoV-2 at the time of data collection. SETTING: Miami-Dade and Broward counties, Florida. RESULTS: White Latino/a/x, bachelor's educated respondents, and those with high levels of trust in community organizations had significantly greater odds of vaccination. CONCLUSION: Community organizations may be key to improving vaccine uptake among marginalized Latino/a/x SGM for COVID-19 and other emerging communicable diseases, such as meningitis and Mpox (monkeypox). The results of this study suggest that tailored public health messaging and additional funding for vaccine distribution are needed to better equip community organizations with the resources they need to serve this population.

La identificación étnica en los registros de salud: experiencias y percepciones en el pueblo mapuche de Chile y Argentina / Ethnic identification in health records: experiences and perceptions of the Mapuche people of Chile and Argentina

Este diagnóstico se enmarca en el proyecto "Enfoque étnico en las fuentes de datos y estadísticas de salud" que tiene como ejes orientadores la territorialidad de los pueblos indígenas, el aprendizaje a partir de experiencias concretas y la participación de diversos actores sociales. En lo específico este artículo tiene como objetivo presentar la sistematización de las experiencias de inclusión de la diferenciación étnica referida al pueblo Mapuche en las estadísticas vitales y fuentes de datos en salud de la Región de la Araucanía (Chile) y la Provincia de Neuquén (Argentina), considerando la dimensión territorial binacional. Para tener una perspectiva amplia sobre las experiencias concretas implementadas en este tema, sus fortalezas y debilidades, así como para comprender el contexto y los fundamentos que las sustentan desde la visión de los propios actores sociales, este diagnóstico se basa en a) la revisión sistemática de los censos, encuestas y registros administrativos y de salud, y b) la realización de entrevistas semi estructuradas a autoridades mapuches y no mapuches a cargo de instituciones que producen estadísticas, principalmente sanitarias. Los resultados muestran una situación paradójica: por un lado, en Chile no existe un marco constitucional ni legislativo para el ejercicio de los derechos fundamentales de los pueblos indígenas. No obstante, y principalmente como respuesta a las demandas del pueblo Mapuche, se cuenta con variadas experiencias de inclusión del enfoque étnico en censos, encuestas, registros sanitarios y otros. En el plano cualitativo, los entrevistados no mapuches se muestran a favor de consolidar estos procesos, que se perciben incipientes. Desde el punto de vista de los representantes mapuches de Chile y Argentina la situación es clara: se requiere de estadísticas diferenciadas que permitan su visibilización como pueblos, pero manteniendo el control social sobre la información.
