Rationale The COVID-19 pandemic poses extraordinary challenges to public health. Objective Because the novel coronavirus is highly contagious, the widespread use of preventive measures such as masking, physical distancing, and eventually vaccination is needed to bring it under control. We hypothesized that accepting conspiracy theories that were circulating in mainstream and social media early in the COVID-19 pandemic in the US would be negatively related to the uptake of preventive behaviors and also of vaccination when a vaccine becomes available. Method A national probability survey of US adults ( N = 1050) was conducted in the latter half of March 2020 and a follow-up with 840 of the same individuals in July 2020. The surveys assessed adoption of preventive measures recommended by public health authorities, vaccination intentions, conspiracy beliefs, perceptions of threat, belief about the safety of vaccines, political ideology, and media exposure patterns. Results Belief in three COVID-19-related conspiracy theories was highly stable across the two periods and inversely related to the (a) perceived threat of the pandemic, (b) taking of preventive actions, including wearing a face mask, (c) perceived safety of vaccination, and (d) intention to be vaccinated against COVID-19. Conspiracy beliefs in March predicted subsequent mask-wearing and vaccination intentions in July even after controlling for action taken and intentions in March. Although adopting preventive behaviors was predicted by political ideology and conservative media reliance, vaccination intentions were less related to political ideology. Mainstream television news use predicted adopting both preventive actions and vaccination. Conclusions Because belief in COVID-related conspiracy theories predicts resistance to both preventive behaviors and future vaccination for the virus, it will be critical to confront both conspiracy theories and vaccination misinformation to prevent further spread of the virus in the US. Reducing those barriers will require continued messaging by public health authorities on mainstream media and in particular on politically conservative outlets that have supported COVID-related conspiracy theories.

This meta-analysis was conducted to understand the factors underlying effective messages to counter attitudes/beliefs based on misinformation. Because misinformation can lead to poor decisions about consequential matters and is persistent and difficult to correct, debunking it is an important scientific and public policy goal. This meta-analysis (k = 52, N = 6,878) revealed large effects for: presenting misinformation (2.41 ≤ d ≤ 3.08), debunking (1.14 ≤ d ≤ 1.33), and the persistence of misinformation in the face of debunking (0.75 ≤ d ≤ 1.06). Persistence was stronger and the debunking effect was weaker when audiences generated reasons in support of the initial misinformation. A detailed debunking message containing new details of the information currently recommended in various editorial policies, such as Retraction Watch, correlated positively with the debunking effect. Surprisingly, however, a detailed debunking message correlated positively with the misinformation-persistence effect. (141 words)

In keeping with the growing movement in scientific publishing toward transparency in data and methods, we propose changes to journal authorship policies and procedures to provide insight into which author is responsible for which contributions, better assurance that the list is complete, and clearly articulated standards to justify earning authorship credit. To accomplish these goals, we recommend that journals adopt common and transparent standards for authorship, outline responsibilities for corresponding authors, adopt the Contributor Roles Taxonomy (CRediT) (docs.casrai.org/CRediT) methodology for attributing contributions, include this information in article metadata, and require authors to use the ORCID persistent digital identifier (https://orcid.org). Additionally, we recommend that universities and research institutions articulate expectations about author roles and responsibilities to provide a point of common understanding for discussion of authorship across research teams. Furthermore, we propose that funding agencies adopt the ORCID identifier and accept the CRediT taxonomy. We encourage scientific societies to further authorship transparency by signing on to these recommendations and promoting them through their meetings and publications programs.

A US national probability-based survey during the early days of the SARS-CoV-2 spread in the US showed that, above and beyond respondents’ political party, mainstream broadcast media use (e.g., NBC News) correlated with accurate information about the disease's lethality, and mainstream print media use (e.g., the New York Times) correlated with accurate beliefs about protection from infection. In addition, conservative media use (e.g., Fox News) correlated with conspiracy theories including believing that some in the CDC were exaggerating the seriousness of the virus to undermine the presidency of Donald Trump. Five recommendations are made to improve public understanding of SARS-CoV-2.

Why has the public persisted in believing that violent crime is a widespread national problem in the U.S. despite declining trends in crime and the fact that crime is concentrated in urban locations? Cultivation theory suggests that widespread fear of crime is fueled in part by heavy exposure to violent dramatic programming on prime-time television. Here we explore a related hypothesis: that fear of crime is in part a by-product of exposure to crime-saturated local television news. To test this, as well as related and competing hypotheses, we analyzed the results of a recent national survey of perceived risk; a 5-year span of the General Social Survey (1990)(1991)(1992)(1993)(1994); and the results of a recent survey of over 2,300 Philadelphia residents. The results indicate that across a wide spectrum of the population and independent of local crime rates, viewing local television news is related to increased fear of and concern about crime. These results support cultivation theory's predicted effects of television on the public.
