Does mask-wearing decrease support for women politicians?

Does the type of mask matter?

In two studies, our team tested a novel theory-grounded health messaging approach combining death reminders with exposure to an NHS prime on the spokesperson's facemask.

We assessed the evidential value of the large literature (kΒ = 643–825 studies) investigating the mortality salience (MS) hypothesis from terror management theory, employing a multitool assessment approach. First, we reviewed and evaluated recent efforts to replicate past experiments testing the MS hypothesis, summarizing the conflicting evidence and arguments to the evidential value of the MS literature. Next, we performed a random effects meta-analysis on the MS literature using multiple bias-correction meta-analytic techniques, including selection models, precision-effect test and precision-effect estimate with standard errors, weighted average of adequately powered studies and weighted least square, as well as the more recently developedΒ p-curve andΒ z-curve. Overall, the different meta-analytic tools often pointed to conflicting conclusions, reflecting methodological and philosophical differences among these tools. A synthesis of our findings suggests there are nonzero effects underlying some studies of the MS hypothesis, although the effects are highly heterogeneous, most studies are underpowered, and many individual effects may be spurious. We recommend future replications to assume a smaller effect size (rΒ = .18) and to strictly follow expert guidance in the experimental protocol. Given the conflicting findings that emerged, we suggest future attempts to evaluate other literature would benefit from a multitool assessment approach.

Terror Management Theory

Thorough and comprehensive analysis of the mortality salience literature by @benchill.bsky.social, @stevenheine.bsky.social and colleagues concludes genuine nonzero effects exist (r = .18) alongside some spurious effects.

"...increasing U.S. public support for an evidence-based redistributive policy across racial/ethnic and partisan lines is possible with a well-designed and pretested message strategies that center shared values, describe policy efficacy, and include a call to collective action."

"But the expectation of easy and perfect replication of experimental findings from one context to the next is probably unrealistic. Rather, the experiment should be one tool within a toolkit containing other useful methods of inquiry: the survey, the interview, the case study, the simulation."
