Individuals lack the ability to accurately detect emotional piloerection.

Piloerection (e.g., goosebumps) is an essential thermoregulatory and social signaling mechanism in non-human animals. Although humans also experience piloerection-often being perceived as an indicator of profound emotional experiences-its comparatively less effective role in thermoregulation and communication might influence our capacity to monitor its occurrence. We present three studies (total N = 617) demonstrating participants' general inability to detect their own piloerection events and their lack of awareness that piloerection occurs with a similar frequency on multiple anatomical locations. Self-reported goosebumps were more frequent than observed piloerection. However, only 31.8% of self-reports coincided with observable piloerection, a bias unrelated to piloerection intensity, anatomical location, heart-rate variability, or interoceptive awareness. We also discovered a self-report bias for the forearm, contradicting the observation that piloerection occurs with equal frequency on multiple anatomical locations. Finally, there was low correspondence between self-reports of being "emotionally moved" and observed piloerection. These counterintuitive findings not only highlight a disconnect between an obvious physiological response and our capacity for self-monitoring, but they underscore a fascinating divergence between human and non-human species. Although piloerection is vital in non-human organisms, the connection between piloerection and psychological experience in humans may be less significant than previously assumed, possibly due to its diminished evolutionary relevance.

Science beliefs, political ideology, and cognitive sophistication.

Some theoretical models assume that a primary source of contention surrounding science belief is political and that partisan disagreement drives beliefs; other models focus on basic science knowledge and cognitive sophistication, arguing that they facilitate proscientific beliefs. To test these competing models, we identified a range of controversial issues subject to potential ideological disagreement and examined the roles of political ideology, science knowledge, and cognitive sophistication on science beliefs. Our results indicate that there was surprisingly little partisan disagreement on a wide range of contentious scientific issues. We also found weak evidence for identity-protective cognition (where cognitive sophistication exacerbates partisan disagreement); instead, cognitive sophistication (i.e., reasoning ability) was generally associated with proscience beliefs. In two studies focusing on anthropogenic climate change, we found that increased political motivations did not increase polarization among individuals who are higher in cognitive sophistication, which indicates that increased political motivations might not have as straightforward an impact on science beliefs as has been assumed in the literature. Finally, our findings indicate that basic science knowledge is the most consistent predictor of people's beliefs about science across a wide range of issues. These results suggest that educators and policymakers should focus on increasing basic science literacy and critical thinking rather than on the ideologies that purportedly divide people.

The physiological study of emotional piloerection: A systematic review and guide for future research.

This paper provides an accessible review of the biological and psychological evidence to guide new and experienced researchers in the study of emotional piloerection in humans. A limited number of studies have attempted to examine the physiological and emotional correlates of piloerection in humans. However, no review has attempted to collate this evidence to guide the field as it moves forward. We first discuss the mechanisms and function of non-emotional and emotional piloerection in humans and animals. We discuss the biological foundations of piloerection as a means to understand the similarities and differences between emotional and non-emotional piloerection. We then present a systematic qualitative review (k = 24) in which we examine the physiological correlates of emotional piloerection. The analysis revealed that indices of sympathetic activation are abundant, suggesting emotional piloerection occurs with increased (phasic) skin conductance and heart rate. Measures of parasympathetic activation are lacking and no definite conclusions can be drawn. Additionally, several studies examined self-reported emotional correlates, and these correlates are discussed in light of several possible theoretical explanations for emotional piloerection. Finally, we provide an overview of the methodological possibilities available for the study of piloerection and we highlight some pressing questions researchers may wish to answer in future studies.

The role of facial coloration in emotion disambiguation.

Previous research has demonstrated that some pairs of emotion expressions are confusing to observers because they share common facial-muscular expressive features. Recent research has suggested that another expressive feature, facial coloration, can facilitate the disambiguation of these emotion expressions. The current work tests this hypothesis by presenting participants with pairs of ambiguous emotion expressions with varying facial coloration, then assessing perceived emotion via continuous ratings and categorizations. The results demonstrated that facial coloration can influence perceived emotion within the emotion pairs of anger-disgust (Experiment 1), surprise-fear (Experiments 2a and 2b), and tearful sadness-happiness (Experiment 3). Further, this influence contributed to emotion disambiguation nonuniformly between emotion pairs. Implications discussed include the role of facial coloration in emotion perception, conceptualizations of emotion categories, and the use of posed facial expression stimuli in emotion research.

Beliefs About COVID-19 in Canada, the United Kingdom, and the United States: A Novel Test of Political Polarization and Motivated Reasoning.

What are the psychological consequences of the increasingly politicized nature of the COVID-19 pandemic in the United States relative to similar Western countries? In a two-wave study completed early (March) and later (December) in the pandemic, we found that polarization was greater in the United States (N = 1,339) than in Canada (N = 644) and the United Kingdom. (N = 1,283). Political conservatism in the United States was strongly associated with engaging in weaker mitigation behaviors, lower COVID-19 risk perceptions, greater misperceptions, and stronger vaccination hesitancy. Although there was some evidence that cognitive sophistication was associated with increased polarization in the United States in December (but not March), cognitive sophistication was nonetheless consistently negatively correlated with misperceptions and vaccination hesitancy across time, countries, and party lines. Furthermore, COVID-19 skepticism in the United States was strongly correlated with distrust in liberal-leaning mainstream news outlets and trust in conservative-leaning news outlets, suggesting that polarization may be driven by differences in information environments.

Character deprecation in fake news: Is it in supply or demand?

A major focus of current research is understanding why people fall for and share fake news on social media. While much research focuses on understanding the role of personality-level traits for those who share the news, such as partisanship and analytic thinking, characteristics of the articles themselves have not been studied. Across two pre-registered studies, we examined whether character-deprecation headlines - headlines designed to deprecate someone's character, but which have no impact on policy or legislation - increased the likelihood of self-reported sharing on social media. In Study 1 we harvested fake news items from online sources and compared sharing intentions between Republicans and Democrats. Results showed that, compared to Democrats, Republicans had greater intention to share character-deprecation headlines compared to news with policy implications. We then applied these findings experimentally. In Study 2 we developed a set of fake news items that was matched for content across pro-Democratic and pro-Republican headlines and across news focusing on a specific person (e.g., Trump) versus a generic person (e.g., a Republican). We found that, contrary to Study 1, Republicans were no more inclined toward character deprecation than Democrats. However, these findings suggest that while character assassination may be a feature of pro-Republican news, it is not more attractive to Republicans versus Democrats. News with policy implications, whether fake or real, seems consistently more attractive to members of both parties regardless of whether it attempts to deprecate an opponent's character. Thus, character deprecation in fake news may in be in supply, but not in demand.

A decade of theory as reflected in Psychological Science (2009-2019).

The dominant belief is that science progresses by testing theories and moving towards theoretical consensus. While it's implicitly assumed that psychology operates in this manner, critical discussions claim that the field suffers from a lack of cumulative theory. To examine this paradox, we analysed research published in Psychological Science from 2009-2019 (N = 2,225). We found mention of 359 theories in-text, most were referred to only once. Only 53.66% of all manuscripts included the word theory, and only 15.33% explicitly claimed to test predictions derived from theories. We interpret this to suggest that the majority of research published in this flagship journal is not driven by theory, nor can it be contributing to cumulative theory building. These data provide insight into the kinds of research psychologists are conducting and raises questions about the role of theory in the psychological sciences.

Piloerection is not a reliable physiological correlate of awe.

In scientific and popular literature, piloerection (e.g. goosebumps) is often claimed to accompany the experience of awe, though this correlation has not been tested empirically. Using two pre-registered and independently collected samples (N = 210), we examined the objective physiological occurrence of piloerection in response to awe-inducing stimuli. Stimuli were selected to satisfy three descriptors of awe, including perceptual vastness, virtual reality, and expectancy-violating events. The stimuli reliably elicited self-reported awe to a great extent, in line with previous research. However, awe-inducing stimuli were not associated with the objective occurrence of piloerection. While participants self-reported high levels of goosebumps and "the chills," there was no physical evidence of this response. These results suggest that piloerection is not reliably connected to the experience of awe-at least using stimuli known to elicit awe in an experimental setting.

Fighting COVID-19 Misinformation on Social Media: Experimental Evidence for a Scalable Accuracy-Nudge Intervention.

Across two studies with more than 1,700 U.S. adults recruited online, we present evidence that people share false claims about COVID-19 partly because they simply fail to think sufficiently about whether or not the content is accurate when deciding what to share. In Study 1, participants were far worse at discerning between true and false content when deciding what they would share on social media relative to when they were asked directly about accuracy. Furthermore, greater cognitive reflection and science knowledge were associated with stronger discernment. In Study 2, we found that a simple accuracy reminder at the beginning of the study (i.e., judging the accuracy of a non-COVID-19-related headline) nearly tripled the level of truth discernment in participants' subsequent sharing intentions. Our results, which mirror those found previously for political fake news, suggest that nudging people to think about accuracy is a simple way to improve choices about what to share on social media.

Oh, the things you don't know: awe promotes awareness of knowledge gaps and science interest.

Awe is described as an a "epistemic emotion" because it is hypothesised to make gaps in one's knowledge salient. However, no empirical evidence for this yet exists. Awe is also hypothesised to be an antecedent to interest in science because science is one way to fill those knowledge gaps. Results from four pre-registered studies (N = 1518) indicate that manipulating awe through online (Studies 1a, 1b, and 1c) and virtual reality (Study 2) videos, led to greater awareness of knowledge gaps. Awareness of knowledge gaps was consistently associated with greater science interest and to choosing tickets to a science museum over tickets to an art museum (Study 1b). These effects were not consistently observed on, nor moderated by, other measures related to cognition, religion, and spirituality. However, exploratory analyses showed that science interest was better predicted by positive emotions than by awe. Still, these results provide the first empirical evidence of awe as an "epistemic emotion" by demonstrating its effects on awareness of knowledge gaps. These findings are also extended to the effects of awe on science interest as one possible outcome of awareness of knowledge gaps.

Adolescent's Perceptions of Sexual Relationships Between Students and Teachers.

Very little is known about how people perceive and respond to sexual relationships between students and teachers, and even less is known about how adolescents view these relationships. In this study, a large sample of high school students (N = 1203; Mean age: 16.83) responded to four scenarios describing a sexual relationship between a student and teacher. We manipulated student and teacher age, and the power differential between the student and teacher and we measured perceptions of wrongness and likelihood of reporting the situation. The data indicated that in situations of older students (18 vs. 14 or 16) and younger teachers (21 vs 30 or 40), they are less likely to be perceived as wrong and less likely to be reported. Likewise, situations were judged as more wrong when the power differential between students and teachers was greater. Further, there were strong gender differences, such that females (vs. males) consistently viewed the situations as more wrong and were more likely to report. Implications for future research and policy are discussed.

Religiosity predicts negative attitudes towards science and lower levels of science literacy.

Past research suggests that religion and science may conflict on which is a better tool for explaining the world. This conflict implies that religiosity might negatively impact both attitudes toward science and science knowledge. However, past research has focused mostly on religious affiliation and has not consistently identified such a relation using a general religiosity measure that assesses religious beliefs and religious practice. Using two large, nationally representative datasets as well as two original datasets, and controlling for relevant demographic variables, four studies (N = 9,205) showed that general measures of religiosity are negatively associated with science knowledge, a relation that was partially mediated by an association between religiosity and negative attitudes toward science. Study 2 also showed that parents' reports about their religiosity and its role in their children's upbringing predicted, some 20 years later, their children's attitudes toward science. The studies are correlational but the longitudinal relations in Study 2 suggests that religiosity might undermine science literacy.
