The unique roles of threat perception and misinformation accuracy judgments in the relationship between political orientation and COVID‐19 health behaviors

Not everyone engages in COVID‐19 related preventative health behaviors (PHB;e.g., mask wearing, social distancing) despite their demonstrated effectiveness for mitigating the spread of COVID‐19. In the United States, for instance, PHBs emerged as (and remain) a partisan issue. The current work examines partisan gaps in PHB by considering both informational and perceptual factors related to COVID‐19. Specifically, we focus on politically motivated belief in COVID‐19 (mis)information and simultaneously consider the roles of physical threat and disgust perception. We find that poor performance in misinformation accuracy judgments and subsequently lower COVID‐19 threat perceptions sequentially predict less PHB engagement. In Study 1 (N = 87 US undergraduate students), higher conservatism predicted lower COVID‐19 threat perceptions but not COVID‐19 disgust perceptions. Study 2 (N = 168 US undergraduate students) replicated this effect, while demonstrating that the relationship between stronger conservatism and lower engagement in PHB was mediated by higher accuracy judgments of COVID‐19 misinformation and, in turn, lower perceptions of COVID‐19 threat but not disgust. This suggests that considering threat perception is essential to understanding how politically motivated endorsement of COVID‐19 misinformation shapes PHB. [ FROM AUTHOR]

Tracking the global reduction of marine traffic during the COVID-19 pandemic.

The COVID-19 pandemic has resulted in unparalleled global impacts on human mobility. In the ocean, ship-based activities are thought to have been impacted due to severe restrictions on human movements and changes in consumption. Here, we quantify and map global change in marine traffic during the first half of 2020. There were decreases in 70.2% of Exclusive Economic Zones but changes varied spatially and temporally in alignment with confinement measures. Global declines peaked in April, with a reduction in traffic occupancy of 1.4% and decreases found across 54.8% of the sampling units. Passenger vessels presented more marked and longer lasting decreases. A regional assessment in the Western Mediterranean Sea gave further insights regarding the pace of recovery and long-term changes. Our approach provides guidance for large-scale monitoring of the progress and potential effects of COVID-19 on vessel traffic that may subsequently influence the blue economy and ocean health.

Actual versus perceived infection rates of COVID-19: Impact on distress, behavior and disability.

OBJECTIVE: Accurate threat appraisal is central to survival. In the case of the coronavirus pandemic, accurate threat appraisal is difficult due to incomplete medical knowledge as well as complex social factors (e.g., mixed public health messages). The purpose of this study was to evaluate the degree to which individuals accurately perceive COVID-19 infection rates and to explore the role of COVID-19 threat perception on emotional and behavioral responses both cross sectionally and prospectively. METHODS: A community sample (N = 249) was assessed using online crowdsourcing and followed for one month. COVID-19 threat appraisal was compared with actual COVID-19 infection rates and deaths at the time of data collection in each participant's county and state. It was predicted that actual versus perceived COVID-19 infection rates would only be modestly associated. Relative to actual infection rates, perceived infection rates were hypothesized to be a better predictor of COVID-related behaviors, distress, and impairment. RESULTS: Findings indicated that relative to actual infection, perceived infection was a better predictor of COVID-related outcomes cross sectionally and longitudinally. Interestingly, actual infection rates were negatively related to behaviors cross sectionally (e.g., less stockpiling). Prospectively, these variables interacted to predict avoidance behaviors over time such that the relationship between perceived infection and avoidance was stronger as actual infection increased. CONCLUSIONS: These data suggest that perceived COVID-19 infection is significantly associated with COVID-related behaviors, distress and impairment whereas actual infection rates have a less important and perhaps even paradoxical influence on behavioral responses to the pandemic.
