Critical Race Theory (CRT) has become a flashpoint of elite political discord, yet how Americans actually perceive CRT is unclear. We theorize that Republican elites utilized a strong framing strategy to re-define CRT as an “empty signifier” representing broader racial and cultural grievances. Using a survey and a pre-registered experiment among U.S. adults (N = 19,060), we find that this strategy worked. Republicans exhibit more familiarity with CRT and hold more negatively valenced (and wide ranging) sentiments toward CRT, relative to Democrats. Moreover, compared to teaching the legacy of racism in schools, Republicans are significantly more opposed to teaching CRT while Democrats express greater uncertainty. Our findings suggest that by framing CRT as a broad term that envelopes many grievances (including those beyond the scope of CRT), Republican elites have shaped a subset of Americans’ understanding of and attitudes toward CRT.

 

Even amid the unprecedented public health challenges attributable to the COVID-19 pandemic, opposition to vaccinating against the novel coronavirus has been both prevalent and politically contentious in American public life. In this paper, we theorize that attitudes toward COVID-19 vaccination might “spill over” to shape attitudes toward “postpandemic” vaccination programs and policy mandates for years to come. We find this to be the case using evidence from a large, original panel study, as well as two observational surveys, conducted on American adults during the pandemic. Specifically, we observe evidence of COVID-19 vaccine spillover onto general vaccine skepticism, flu shot intention, and attitudes toward hypothetical vaccines (i.e., vaccines in development), which do not have preexisting attitudinal connotations. Further, these spillover effects vary by partisanship and COVID-19 vaccination status, with the political left and those who received two or more COVID-19 vaccine doses becoming more provaccine, while the political right and the unvaccinated became more anti-vaccine. Taken together, these results point to the salience and politicization of the COVID-19 vaccine impacting non-COVID vaccine attitudes. We end by discussing the implications of this study for effective health messaging.

 

We have been studying the complexation between cationic antimicrobials and polyanionic microgels to create self-defensive surfaces that responsively resist bacterial colonization. An essential property is the stable sequestration of the loaded (complexed) antimicrobial within the microgel under physiological ionic strength. Here we assess the complexation strength between poly(acrylic acid) [PAA] microgels and a series of cationic peptoids that display supramolecular structures ranging from an oligomeric monomer to a tetramer. We follow changes in loaded microgel diameter with increasing [Na+] as a measure of the counterion doping level. Consistent with prior findings on colistin/PAA complexation, we find that a monomeric peptoid is fully released at ionic strengths well below physiological conditions despite its +5 charge. In contrast, progressively higher degrees of peptoid supramolecular structure display progressively greater resistance to salting out, which we attribute to the greater entropic stability associated with the complexation of multimeric peptoid bundles. 

Depression can affect individuals’ attitudes by enhancing cognitive biases and altering perceptions of control. We investigate the relationship between depressive symptoms and Americans’ attitudes regarding domestic extremist violence. We develop a theory that suggests the association between depression and support for political violence depends on conspiracy beliefs, participatory inclinations, and their combination. We test our theory using a two‐wave national survey panel from November 2020 and January 2021. We find that among those who hold conspiracy beliefs and/or have participatory inclinations, depression is positively associated with support for election violence and the January 6 Capitol riots. The participatory inclination dynamic is particularly strong for men. Our findings reveal how the intersection of two concerning features of American society—poor mental health and conspiratorial beliefs—strongly relate to another feature: support for political violence. The results also make clear that interventions aimed at addressing depression can potentially have substantial political consequences.

 

Politics and science have become increasingly intertwined. Salient scientific issues, such as climate change, evolution, and stem-cell research, become politicized, pitting partisans against one another. This creates a challenge of how to effectively communicate on such issues. Recent work emphasizes the need for tailored messages to specific groups. Here, we focus on whether generalized messages also can matter. We do so in the context of a highly polarized issue: extreme COVID-19 vaccine resistance. The results show that science-based, moral frame, and social norm messages move behavioral intentions, and do so by the same amount across the population (that is, homogeneous effects). Counter to common portrayals, the politicization of science does not preclude using broad messages that resonate with the entire population.
