Highlights

• We investigated determinants of liking at zero-acquaintance.

• Perceivers (N = 385) viewed portrait photographs of Targets (N = 146)

• Different perceivers were differently influenced by appearance cues.

• Targets who displayed non-Duchenne (fake) smiles were generally rated less favorably.

• Those high in N or C, but not those low in A, especially disliked fake smiles.

Abstract: We investigated determinants of liking at zero-acquaintance, focusing on individual differences in perceivers’ reactions to appearance cues. Perceivers (N = 385) viewed portrait photographs of Targets (N = 146). Perceiver’s Agreeableness and Extraversion were uniquely associated with liking targets. Targets who expressed positive emotions, looked relaxed, were physically attractive, and looked healthy and energetic, were the most liked. There were substantial individual differences in how Perceivers were influenced by appearance cues. For instance, Perceivers generally rated targets who displayed non-Duchenne (fake) smiles less favorably than targets who did not smile or targets who displayed Duchenne (authentic) smiles. However, non-Duchenne smiles elicited especially negative ratings from Perceivers high in Neuroticism or Conscientiousness, but not from Perceivers low in Agreeableness.

What Makes Things Funny? An Integrative Review of the Antecedents of Laughter and Amusement

What Makes Things Funny? An Integrative Review of the Antecedents of Laughter and Amusement. Caleb Warren, Adam Barsky, A. Peter McGraw. Personality and Social Psychology Review, December 21, 2020. https://doi.org/10.1177/1088868320961909

Abstract: Despite the broad importance of humor, psychologists do not agree on the basic elements that cause people to experience laughter, amusement, and the perception that something is funny. There are more than 20 distinct psychological theories that propose appraisals that characterize humor appreciation. Most of these theories leverage a subset of five potential antecedents of humor appreciation: surprise, simultaneity, superiority, a violation appraisal, and conditions that facilitate a benign appraisal. We evaluate each antecedent against the existing empirical evidence and find that simultaneity, violation, and benign appraisals all help distinguish humorous from nonhumorous experiences, but surprise and superiority do not. Our review helps organize a disconnected literature, dispel popular but inaccurate ideas, offers a framework for future research, and helps answer three long-standing questions about humor: what conditions predict laughter and amusement, what are the adaptive benefits of humor, and why do different people think vastly different things are humorous?

IBM, 3M, PepsiCo Among Leading US Firms That House Chinese Communist Party Units: Leaked Database

IBM, 3M, PepsiCo Among Leading US Firms That House Chinese Communist Party Units: Leaked Database. Eva Fu. Epoch Times, December 22, 2020. https://www.theepochtimes.com/ibm-3m-pepsico-among-leading-us-firms-that-house-chinese-communist-party-units-leaked-database_3628066.html

Hundreds of Chinese Communist Party (CCP) members are embedded within the Chinese divisions of major U.S. corporations, from IBM to PepsiCo to 3M, a leaked CCP-member database revealed.

The existence of Party units within foreign companies in China is hardly surprising, given that the regime mandates any organization with at least three CCP members to form a Party branch. But the 1.95 million CCP member list, which includes names, levels of education, ethnicity, and the Party branches they belong to, was to date the biggest revelation on the scale of the CCP’s influence on international companies.

Most of the members in the database are from the country’s southeastern coastal metropolis of Shanghai.

New York-headquartered tech firm IBM has at least two dozen Party units with 808 members in China.

3M, a manufacturer of consumer and health care goods, including N95 respirators and other medical products critical to preventing COVID-19 spread, employs at least 230 CCP members within five Party units.

PepsiCo, the multinational snack and beverage company, has 45 employees listed under the company’s Party branch committee.

Dow Chemical Company, one of the world’s three largest chemical producers, lists 337 CCP members in four Party committees.

Other notable U.S. firms on the list include Westin Hotel & Resorts owned by Marriott International (23 members); analytics firm Nielsen Holdings (94); leading food company Mars Food (14); and insurance provider MetLife (31).

The U.S. companies and Party branches mentioned are by no means exhaustive. As of 2016, around 75,000 foreign businesses—accounting for over 70 percent of the roughly 106,000 foreign firms in China—have established Party units, according to state-run media People’s Daily.

The development of CCP units picked up pace from 2002, after Beijing’s top leadership “wrote the obligations of nonpublic firms’ Party organizations into the Party charter, providing evidence for the nonpublic firms’ Party organizations to host activities and play their roles,” according to Chinese media reports from 2002.

State media reported that the country currently has nearly 92 million CCP members. While the database represents only a small fraction of the total membership, it’s a key piece of the puzzle for uncovering the regime’s penetration of international companies, said Bill Gertz, national security correspondent for The Washington Times in an interview.

Early this month, the Trump administration imposed travel restrictions on CCP members and their immediate families, reducing the maximum duration of stay for those with B1/B2 visitor visas from 10 years to one month.

The Party Network

Creating more Party units within companies in China has been one of the top priorities for the CCP’s Organization Department, a core Party organ that oversees staffing of government officials nationwide, according to Qi Yu, a former deputy head of the department.

Qi, who currently serves as the Party committee secretary at the Chinese foreign ministry, said at an October 2017 news conference in Beijing that the regime requires corporate Party organizations to “organically integrate Party activities with the firm’s production in order to support companies’ healthy development,” according to People’s Daily.

Most Party organization activities center around patriotic education to ensure employees toe the Party line.

Mars Food’s Shanghai Party branch, for example, marked this year’s traditional Chinese Mid-Autumn Festival by providing products to an event organized by local authorities meant to promote the CCP’s history in the region.

IBM’s Party unit in Zhangjiang Town in Shanghai’s Pudong district was one of 30 foreign firms that participated in local events to commemorate the 90th anniversary of the CCP’s founding in 2011, while members of its Shenzhen branch “actively joined” 2019 activities with the theme “Stay true to the original heart and follow the Party.”

Such activities have met with resistance from staff within some Western firms. The Westin Beijing Financial Street, which opened in 2006, created its Party branch in 2009 with 10 CCP members out of a total staff of 600.

Xu Tao, the hotel’s Party branch secretary, said that he had tried to “incorporate political things into activities accepted by both Chinese and Western employees” to give Westerner staff the impression that “Party branch work are infusing more Chinese elements into the Westin brand and thus make the hotel more locally competitive,” according to a report by state media Xinhua. Xu had organized events to have workers stitch national flags together and to study the “spirit of the Long March,” the CCP army’s retreat in the 1930s.

The “membership in the Chinese Communist Party makes those people devoted not to the nation of China, or to the people of China, but to the political party of the CCP,” said Journalist Gertz. He called such efforts the CCP’s “ideological drive” to “basically take over the world.”

“They [CCP members] see themselves as besieged by the capitalist world, they see themselves as, basically, at ideological war with a non-communist world,” he said on The Epoch Times’ American Thought Leaders program.

“Now the West, the free world, needs to wake up and start fighting back against the Chinese Communist Party.”

3M declined to comment. IBM, PepsiCo, Dow Chemical, Marriott, Nielsen, Mars, and MetLife didn’t respond to a request for comment by press time.

The explosion in happiness studies of the last 20 years did has not improved effect sizes of happiness interventions; the supposed epistemological superiority of positive psychologists has not produced more effective happiness advice

Diminishing Effectiveness of Happiness Interventions: Positive Psychology Stumbles on the Dodo Verdict. Ad Bergsma.

Abstract: Some positive psychologists claim that quantitative research leads to the most effective interventions for the intentional pursuit of happiness. A similar claim made in psychotherapy research resulted in failure; fifty years of experimental research has not improved psychotherapy outcomes. In this essay it is argued that the explosion in happiness studies of the last twenty years did has not improved effect sizes of happiness interventions. The supposed epistemological superiority of positive psychologists has not produced more effective happiness advice. This should not be taken as an encouragement to throw the baby out with the bathwater. If we follow current reasoning in psychotherapy research, we can conclude that positive psychological research can correct misguided or counterproductive happiness advice, but will not offer definitive answers. The individuals making his their own choices on the basis of a personal life philosophy count. A further conclusion is that happiness interventions should not just be about acquiring skills to correct the affective system in our brains, so that we are able to overcome our negativity bias or hedonic adaptation. Intervention should also be about following our emotional action tendencies; promoting doing to do more of what feels right to us and avoiding what causes pain.

People with psychiatric diagnoses typically recall fewer specific and more general memories than diagnoses-free people

Barry, Tom J., David J. Hallford, and Keisuke Takano. 2020. “Autobiographical Memory Impairments as a Transdiagnostic Feature of Mental Illness: A Meta-analysis of Autobiographical Memory Specificity and Overgenerality Amongst People with Psychiatric Diagnoses.” PsyArXiv. December 21. doi:10.31234/osf.io/ab5cu

Abstract: Decades of research has examined the difficulty that people with psychiatric diagnoses, such as Major Depressive Disorder, Schizophrenia Spectrum Disorders, and Posttraumatic Stress Disorder, have in recalling specific autobiographical memories from events that lasted less than a day. Instead, they seem to retrieve general events that have occurred many times or which occurred over longer periods of time, termed overgeneral memory. We present the first transdiagnostic meta-analysis of memory specificity/overgenerality, and the first meta-regression of proposed causal mechanisms. A keyword search of Embase, PsycARTICLES and PsycINFO databases yielded 74 studies that compared people with and without psychiatric diagnoses on the retrieval of specific (k = 85) or general memories (k = 56). Multi-level meta-analysis confirmed that people with psychiatric diagnoses typically recall fewer specific (g = -0.864, 95% CI[-1.030, -0.698]) and more general (g = .712, 95% CI[0.524, 0.900]) memories than diagnoses-free people. The size of these effects did not differ between diagnostic groups. There were no consistent moderators; effect sizes were not explained by methodological factors such as cue valence, or demographic variables such as participants’ age. There was also no support for the contribution of underlying processes that are thought to be involved in specific/general memory retrieval (e.g., rumination). Our findings confirm that deficits in autobiographical memory retrieval are a transdiagnostic factor associated with a broad range of psychiatric problems, but future research should explore novel causal mechanisms such as encoding deficits and the social processes involved in memory sharing and rehearsal.

In English there are few words for smell qualities, smell talk is infrequent, and people find it difficult to name odors in the laboratory; however, there are many languages across the globe that have large smell lexicons

Human Olfaction at the Intersection of Language, Culture, and Biology. Asifa Majid. Trends in Cognitive Sciences, December 18 2020. https://doi.org/10.1016/j.tics.2020.11.005

Highlights

*  The human sense of smell is far more acute than previously thought, yet it is still commonly believed that there is no language of smell.

*  In English there are, indeed, few words for smell qualities, smell talk is infrequent, and people find it difficult to name odors in the laboratory. However, the cross-cultural data show a different picture.

*  There are many languages across the globe that have large smell lexicons (smell can even appear in grammar) in which smell talk is also more frequent and naming odors is easy.

*  In different cultural and ecological niches odors play a significant role in everyday life.

*  These differences in smell language can have consequences for how people think about odors.

Abstract: The human sense of smell can accomplish astonishing feats, yet there remains a prevailing belief that olfactory language is deficient. Numerous studies with English speakers support this view: there are few terms for odors, odor talk is infrequent, and naming odors is difficult. However, this is not true across the world. Many languages have sizeable smell lexicons — smell is even grammaticalized. In addition, for some cultures smell talk is more frequent and odor naming easier. This linguistic variation is as yet unexplained but could be the result of ecological, cultural, or genetic factors or a combination thereof. Different ways of talking about smells may shape aspects of olfactory cognition too. Critically, this variation sheds new light on this important sensory modality.

Do Different Ways of Talking About Smell Affect How We Think About Smell?

What, if any, cognitive consequences are there as a result of these diverse smell vocabularies? The realization of differential linguistic coding of olfaction has only recently been taken seriously by the cognitive science community, so studies of the cognitive consequences are nascent (see also Box 3). The studies to date suggest a mixed picture.

Box 3

Hunter-Gatherers and Wine Experts: Everyday versus Institutional Language and Cognition

The fact that some cultures have smell lexicons has been interpreted by some as a type of ‘expertise’ affecting language and thought [28] (Figure I). While lay English speakers show a lack of regard for smell, wine experts, perfumers, and the gourmand have cultivated their noses. So, are the wine experts’ and hunter-gatherers’ smell knowledge equivalent? The answer appears to be no. Although expertise certainly has relevance for understanding the relationship between olfaction and language, there are important differences between everyday cultural knowledge and institutional expertise.

The trajectory of learning is critically different between everyday and expert knowledge: people acquire cultural categories effortlessly in childhood, via language, and with little explicit instruction; experts, by contrast, acquire categories from institutions effortfully, usually later in life through explicit instruction, and knowledge has to be mapped onto language. In addition, I propose three specific properties that differ between everyday and institutional olfactory language and cognition.

Experts Individuate, Cultures Categorize

Everyday categories generalize over exemplars to capture broad similarities. Jahai, for example, distinguishes plʔeŋ smells (characteristic of blood, raw meat, fish, etc.) from cŋɛs smells (e.g., bat dropping, smoke, petrol, etc.) and haʔɛ̃t smells (e.g., shrimp paste, sap of rubber tree, rotten meat, etc.), all of which are simply stinky in English. By contrast, experts are trained to distinguish very closely related entities, for example, distinguishing fake jasmine from the real thing. This is why when experts develop lexicons, they tend to focus on specifying and identifying an exact odor [121,122].

Specialist Knowledge Is Subdomain Specific, but Cultural Knowledge Is Domain General

The hunter-gatherer Jahai name odors with higher consensus than their Western counterparts and apply their basic smell terms to novel odors they have never previously encountered [39]. Wine experts, too, show high consensus when describing the smell of wine [123., 124., 125., 126.], but this ability does not generalize beyond their domain of expertise: they are no better than laypeople at describing the smell of coffee or naming other everyday odors [123,125]. Similarly, wine experts have better memory [123] and imagery [127] only for odors in their domain of expertise (see also [122]).

Specialist Olfactory Cognition Is Language Independent, but Cultural Cognition Is Language Dependent

There is a strong link between language and memory for odors in everyday cognition: odors named correctly are remembered more accurately [128,129]. However, specialists do not show this relationship between odor naming and odor memory for their domain of expertise and inhibiting the use of language during encoding does not impair odor memory [123]. In sum, the evidence to date suggests that everyday but not specialist olfactory memory relies on language in the moment.

Olfactory Language and Emotion

Within a language, the same odor is experienced as pleasant or unpleasant depending on the label it is given [100,101], raising the question of whether cross-cultural differences in naming strategies may likewise affect the perceived pleasantness of an odor. It appears they do not. Jahai and Dutch speakers use different strategies to talk about odors (abstract basic smell terms vs concrete source-based descriptions) and this may therefore lead to differences in the perceived pleasantness of odors, with some accounts predicting that abstract concepts are more valenced whereas others suggest they are more detached from sensory experience. By comparing facial expressions elicited by monomolecular odors while participants were engaged in an odor-naming task, Majid and colleagues found that both groups had the same initial affective responses to odors, regardless of the odor language they used [39]. These results suggest that the pleasantness of an odor is experienced swiftly and universally, whereas odor identification is slower and cross-culturally diverse. Critically, the role of language in odor perception may differ in important ways depending on whether it is recruited during production or comprehension (Box 2).

Olfactory Language and Cross-Modal Associations

Olfactory and visual information are intimately tied, with connectivity analyses showing that integration happens as early as the primary olfactory cortex [102], and when people are asked to associate odors with colors they do so in systematic ways [58,103., 104., 105., 106.]. This could happen in at least two ways: odor perceptual representations could link directly to color due to statistical co-occurrences in the environment or the association between odors and colors could be mediated by language. According to the language-mediated account of odor–color associations, if people use basic smell words to name abstract odor qualities (e.g., musty) they should show weaker odor–color associations than those who refer to their source (e.g., smells like banana). To test this, one study compared urban-dwelling Thai and hunter-gatherer Maniq (who both have basic smell vocabulary) with urban-dwelling Dutch participants (who overwhelmingly use source-based odor naming) and found that odor–color associations were mediated by language [103]. People had weaker odor–color associations when they used basic smell vocabulary, but when source-based vocabulary was used, color choices more accurately reflected their source. By the time a child is 6 years old, odor–color associations are culture specific, and odor naming plays an important role in their development [104].

Concluding Remarks

Human olfaction serves diverse functions some of which are shared across species. But humans also uniquely use olfaction deliberatively for religious, medicinal, and aesthetic purposes — and language plays a critical role in coordinating these activities. Despite the prevailing view that there is no olfactory language, this review highlights diverse communities worldwide that have basic smell vocabularies and where smell talk is more frequent. Rather than focusing on constrained experimental tasks, olfactory researchers could benefit from considering human olfaction in all of its contexts to study how people across the globe use, manipulate, and talk about odors in their day-to-day contexts (see Outstanding Questions).

Outstanding Questions

Are smell words more likely to lexicalize some odors than others? Is there a predictable order of lexicalization or is each odor vocabulary uniquely fitted to its ecological and cultural niche?

Do languages with basic smell terms also have more smell-associated words? Modality exclusivity norms from English reveal a set of smell-associated words, although these are fewer in number than for the other senses. Studies have confirmed the same trend in several European languages (Dutch [130], Italian [131,132], Russian [133], Serbian [134]) and in Mandarin [135]. Critically, no norms have yet been collected from languages with attested smell vocabularies.

Non-literal metaphorical use of smell language appears in some languages (e.g., Seri [80]) but not others (e.g., Jahai). What smell metaphors are used across languages and how common are they?

Before abandoning the deodorization hypothesis, it is worth considering some complications. Words and meanings change over time: words currently with a smell meaning may not have had that meaning in the past and vice versa. Historical comparison is reliant on text written in a standardized, formal register. Smell may be less frequent there because of taboos surrounding smelliness [136]; conversely, smell may be more evident in slang. Intriguingly, there is a large slang lexicon for the ‘nose’ [137], but no systematic study of smell itself.

Language plays a critical role in odor–color associations but perhaps not in odor–temperature [138] or odor–music [139] associations. Which cross-modal odor associations are mediated by language and culture?

Is the relationship between language and olfaction symmetrical or asymmetrical? Evidence from Western languages suggests it may be symmetrical (Box 2); is the same true for languages with basic smell terms?

Does the trajectory of learning olfactory language differ between children and adults (Box 3)? What conditions give rise to domain-general versus domain-specific olfactory abilities?

Comparing the levels of pro-attitudinal media exposure between partisan groups revealed that liberals’ selective exposure was statistically higher than that of conservatives’ selective exposure

How Do Partisans Consume News on Social Media? A Comparison of Self-Reports With Digital Trace Measures Among Twitter Users. Jieun Shin. Social Media + Society, December 18, 2020. https://doi.org/10.1177/2056305120981039

Abstract: There are growing concerns that social media exacerbates the selective exposure of audience members to content that supports their political views. However, despite the hype, the existing literature does not fully address the extent to which social media users selectively consume like-minded news stories, in part due to different methodologies. In an attempt to move toward a common framework, this study examined the partisan selective exposure of a representative sample of Twitter users by combining survey data with digital trace data. Specifically, the study linked survey responses (n = 558) from Twitter users with their media following and exposure to news via their friends. The study found that selectivity bias was present in all types of data, including self-reported media consumption (survey), media following (Twitter), and indirect exposure to media (Twitter). However, the study found some differences between self-reports and digital measures such that the overlaps in media diets between partisan groups were much larger based on the digital trace data than the self-reported data. In addition, the study observed an asymmetric pattern of selective exposure between conservatives and liberals in the digital trace data, but not in the self-reported data. The implications of these findings are discussed with reference to the contemporary news environment, hostile media effects, and normative assumptions of selective exposure.

Discussion

This study investigated whether Twitter users selectively consumed ideological news media by linking survey responses from US Twitter users with their behavioral data. First, the study found that an individual’s political ideology was significantly associated with ideological bias in news consumption in all types of data, which included self-reported media consumption on Twitter (survey), media following (digital trace), and indirect exposure to media via friends (digital trace). Conservatives were significantly more likely to use right-wing media sources, whereas liberals were more likely to use left-wing media sources. In fact, of all variables that were included in the three tested models, an individual’s political identity was by far the strongest predictor of ideological media use. A partisan’s preference for congenial media consumption has been extensively shown in previous studies (Garrett, 2009; Iyengar & Hahn, 2009; Peterson et al., 2019; Stroud, 2008). However, this study demonstrated that this pattern holds for various types of media measures when drawing on a representative sample of Twitter users.

However, despite the significant association between political ideology and media diet at the individual level, the distribution of media slants between two partisan groups overlapped much more in the digital trace data than in the self-reported data. The OVL coefficients in the trace data, which included both following and exposure through friends, were almost two times larger than those of the self-reported data. This finding may be due to the possibility that self-reported media consumption is biased in a direction that mirrors the political identity of the individual (Brenner & DeLamater, 2016). On the contrary, actual media following and exposure via friends on Twitter may be influenced by other factors (e.g., media popularity, reputation, and trending topics) that deviate from the partisan motivation of the individual. Such a finding is consistent with previous studies that observed a moderate level of cross-cutting media exposure on social media (Bakshy et al., 2015; Eady et al., 2019). Similarly, a line of research using a network approach to audience overlap (Mukerjee et al., 2018; Nelson & Webster, 2017) showed a strong common set of media repertoires among individuals across the spectrum.

Focusing on the overall convergence or divergence in media diets between partisans can shed additional light on the selective exposure phenomenon. Traditionally, studies investigating selective exposure (e.g., Iyengar & Hahn, 2009) primarily focused on the directional relationship between partisanship and ideological media choices. That is, Democrats are more likely to select liberal media, whereas Republicans are more likely to select conservative media. However, as Guess (2020) pointed out, “the literature on partisan selective exposure is largely silent on the question of how much of a preference for congenial content is acceptable or desirable” (p. 15). Although there is currently no consensus on this issue, accumulating references over time and across different platforms may be a starting point for more discussion around this topic.

Furthermore, this study observed an asymmetric pattern of selective exposure between conservatives and liberals in actual media consumption. Based on the self-reported data, both groups of partisan respondents similarly indicated their congenial media bias. However, comparing the levels of pro-attitudinal media exposure between partisan groups revealed that liberals’ selective exposure was statistically higher than that of conservatives’ selective exposure. That is, whereas the self-reported data showed a mirroring pattern between partisan groups departing from the neutral point, conservatives’ actual media following and exposure were shifted toward the liberal side of the spectrum. In addition, the study found that for conservatives, although the most influential media outlet was Fox News both in terms of following and indirect exposure, the top 10 most-followed and most-encountered news sources included liberal-leaning outlets such as CNN, the NYT, and the Washington Post. By contrast, the top 10 news sources for liberals did not include any conservative sources, even Fox News.

However, this finding does not necessarily suggest that conservatives have a higher tolerance toward a different point of view. A large body of literature has generally found that conservatives tend to be less tolerant of ideological outgroups (Ganzach & Schul, 2020) and ambiguity than liberals (Jost, 2017). Then, how can we explain this seemingly inconsistent finding? Several possible explanations exist. First, the current media echo-system is characterized by few prominent conservative news sources, with the exception of Fox News (Faris et al., 2017; Grossmann & Hopkins, 2016). Previous studies (e.g., Mitchell et al., 2014) have shown that whereas liberals trust a wide array of news sources, such as CNN, MSNBC, NYT, and WP, which are relatively long-standing and mainstream media sources, conservatives name only a single news source (Fox News) as their trusted media outlet. Due to such limited options, conservatives may consume news media that seems to be ideologically inconsistent. Alternatively, the Twitter environment itself may be a contributing factor. As this study and a Pew Research study (Wojcik & Hughes, 2019) have found, more Twitter users seem to be liberals (i.e., Democrats) than conservatives (i.e., Republicans). This imbalance may promote the visibility of liberal-leaning media through user media sharing compared with conservative-leaning media.

The findings of this study have implications for the effects of media on partisans and offer an opportunity to debate whether selective exposure to diverse opinion is normatively positive. Using field experiments, Bail et al. (2018) observed that when social media users are exposed to opposing political views, they become even more extreme in their views. This backfire effect was stronger for Republicans. Such a finding seems to be related to a stronger hostile media effect among Republicans than Democrats (Lin et al., 2016; Shin & Thorson, 2017). Similarly, numerous surveys have shown that conservatives place less trust in mainstream news media than liberals (Gallup, 2018; Jurkowitz et al., 2020). This stronger hostile media perception among conservatives could potentially result in them resorting to unsubstantiated information sources such as disinformation campaigns (Hjorth, Adler-Nissen, 2019).

Methodologically, this study advances our understanding of selective exposure on social media by linking self-reported estimates of media consumption with digital trace data. Media scholars (Garrett, 2013; Prior, 2013) have called for objective measures of selective exposure via tracking data due to biases observed in self-reported responses. For this reason, digital trace data are increasingly being used as an alternative to surveys. However, tracking data alone have drawbacks, such as a lack of accurate demographic information (e.g., even a simple task as to whether the account is a bot or a human). In addition, there are ethical challenges associated with the use of digital trace data such as obtaining consent from the users (Williams et al., 2017). Therefore, a combination of both approaches can make an important contribution to the literature. Consistency or inconsistencies arising from different measures are real opportunities to enhance our understanding of selective exposure, rather than rejecting one form in favor of another (Garrett, 2013).

In this study, some incongruencies between self-reports and digital trace were documented. In particular, conservatives’ shift toward the left in their news consumption in the digital trace data compared with the self-reported data deserves more attention. This suggests a gap between what survey respondents report and what they actually do on social media. Ascertaining a source of the gap could help us better understand ideological selective exposure.

This study has several limitations. First, the study used a predefined set of news outlets to measure the slant in media diets for news following and exposure via friends, whereas respondents were asked to self-report their ideological news consumption using approximate proportions. When answering this survey question, respondents may have considered other outlets that were not included in the predefined set. In particular, a retrospective assessment of ideological media consumption can be susceptible to biased responses. Future research is needed to compare other self-reported measures of media consumption, such as name listing or open-ended survey prompts, to improve the accuracy of the results. In addition, the findings were drawn from a relatively small sample of Twitter users (maximum 558 users in the full sample, 255 users in the overlapping sample) who opted to provide their account information. Future studies are needed to expand the sample size to more accurately assess the demographics and media behaviors of Twitter users.

Conclusion

Despite these limitations, this study contributes to the literature of selective exposure by examining various measures of media consumption among social media users. The findings of this study provide overall support for the principle of selective exposure at the individual level. However, it was also found that the average media diets of the left and the right overlap considerably. This finding offers important implications for current debates about the prevalence of selective exposure on social media. These findings warrant more research on the various factors (e.g., Messing & Westwood, 2014) influencing the news choices of social media users in conjunction with political motivation.

Furthermore, this study provided some evidence of asymmetric media behavior between the left and the right. This suggests that the extent of cross-cutting media exposure could be different between conservatives and liberals. Selective exposure and partisan polarization have traditionally been treated as symmetrical concepts. This asymmetric pattern requires further investigation regarding the causes as well as the consequences. In particular, the consequences of frequently consuming challenging information deserve more attention, including a hostile perception of the media and lack of trust in journalism.

Masculinity and immune system efficacy in men. Judyta Nowak-Kornicka,Barbara Borkowska,Bogusław Pawłowski. PLoS One, December 14, 2020. https://doi.org/10.1371/journal.pone.0243777

Abstract: Masculinity-related morphological traits are supposed to be honest indicators of a man's biological quality. While some studies showed that sexually dimorphic traits are related to various aspects of biological condition such as general health, immunity or fertility, still little is known about the relationship between masculine traits and the effectiveness of innate and adaptive immunity in humans. The aim of this study was to see if masculine traits, which are dependent on androgen levels in foetal and pubertal stages of development, are related to the immune quality in healthy men. The immune quality was evaluated for 91 healthy men aged 19–36 years. Immunity measurements included innate and adaptive parameters. General health status, age, testosterone level, BMI, physical activity, and smoking were controlled. The shoulder-to-hip ratio (SHR), 2D:4D digit ratio and hand-grip strength (HGS) were used as markers of masculinization. The regressions showed that when controlling for confounds, masculinity-related traits were in general not related to innate and adaptive immunity. Only a weak association was observed for right 2D:4D ratio and T-lymphocyte counts (but it becomes non-significant after adjustment for multiple comparisons). Our results do not support the premise that masculinity is a cue for immunological quality in men. However, the positive association between right 2D:4D and T lymphocytes might suggest that further studies are needed to verify if androgen stimulation in prenatal development might be related to immunity in adulthood.

The relationship between masculinity traits and controlled factors

Because HGS was associated with such controlled factors as a participant's age, BMI and body height (see section "IV" in S1 File, the correlation between body height and BMI was weak (R = -0.22)), we also conducted the analyses adjusted for these. The separate models were carried out for each immune function. These analyses also revealed that HGS is not related to any of the analysed immune parameters.

According to the evolutionary hypothesis concerning the biological implications of sexually selected traits which are commonly perceived as attractive (good genes hypothesis), and are also involved in intra-sexual competition and costly to produce (handicap hypothesis), we assumed that masculinity in men aged 19–36 might serve as a signal reflecting an individual's biological quality. The aim of this study was to check if body masculinity of healthy men is related to immune function, which is one of the most important fitness-related characteristics of an organism, determining risk of morbidity and mortality in all life stages. In general, we found no association between masculinization markers and either innate or adaptive immune responses, even when controlling for a participant's age, BMI, free-testosterone levels, smoking status or sport activity.

The finding in the current study of no associations between SHR or HGS and any of the studied immune parameters, indicates that these indirect markers of pubertal or current testosterone do not reflect immune functioning. To the best of our knowledge, there is no study linking SHR with any of the immune-associated biomarkers, and there have only been limited studies testing the relationship between muscle mass and immunity [45], with only one study directly testing CD4+ count and muscle functions itself as measured by strength [65]. This was, however, only in patients with an HIV-associated immune injury. Raso et al. (2013) [65] showed that disease-associated decreases in HGS are associated with a lower CD4+ count. There are also several studies only indirectly linking HGS with immunity-related characteristics, showing that inflammation-associated diseases [66, 67] or autoimmune disorders [68] are related to lower HGS. Our study is the first to demonstrate that a V-shaped upper body, reflected in SHR and muscle function and measured by HGS, is not associated with immunity in healthy men.

Our results investigating the relationship between masculinity, post-vaccination and lymphocyte-proliferation responses are in contrast to the limited human studies testing ICHH in facial masculinity and the strength of antibody or cytokine response after immune stimulation [e.g. 15, 19]. It is worth underlining, however, that in these two studies the authors analysed only facial (and not body) perception and they did not use anthropometry. Furthermore, Rantala et al. (2012) [15] measured immune response against the hepatitis B virus i.e. conservative antigens, whereas we studied immune response to the influenza virus i.e. a fast evolving/mutating antigen. The lack of association between analyzed markers of masculinization and immune reactivity in response to potentially harmful factors may therefore indicate that the immune response can differ depending on the antigen in question. It is also possible that some vaccine-contained antigens and/or in vitro lymphocyte stimulation may be inadequate to reflect general immune quality. Our results also contradict studies that have indirectly measured immunity (e.g. frequency of infection) and its relationship with facial masculinity (rated and/or morphometric) finding that men with more masculine faces (rated and measured) reported a lower frequency of colds and flu [16, 62]. It is therefore possible that facial dimorphism has more signalling significance than body masculinity (or the traits studied in this paper). On the other hand, Foo et al. (2017a) [63] did not find the relationship between rated facial masculinity and various immune functions measured in saliva. Therefore in the future it will be important for studies to include both facial and body traits related to masculinity in order to address this discrepancy in the literature.

Due to the mixed findings in humans, we should also consider that the immunosuppressive role of androgens (the basis of ICHH) is still controversial. It has been suggested that androgens have immunomodulatory rather than immunosupressive properties [18, 21] and this was also observed in a group of participants included in this study (see S3 Table in S1 File). It may also be the case that in contrast to experimental or in-vitro studies which, in accordance to ICHH, expect a negative relationship between immunity and masculinity, in correlational studies (such as ours) the lack of associations might also be interpreted in the framework of the ICHH and good genes hypothesis. This is because testosterone-induced immune suppression in highly masculine men may suppress immunity to a level similar to that observed in men with a lower immune quality. Consequently, more masculine males might only be a little healthier than average [69], and there may be no noticeable difference in immune quality between those with high and low-masculinity observed in correlational studies. In other words, if, in accordance with ICHH, only individuals with a well-functioning immune response bear a cost associated with testosterone-derived immunosuppression, we should expect that men with a higher expression of masculine traits only have a marginally better, or perhaps a very similar level, of immune quality as men with a lower masculinization level.

Our results are also consistent with recent reports showing that physically attractive traits such as male body height [64] or components of men’s facial attractiveness [63] are not related to immune effectiveness–at least in Western, well-fed societies. The Immune Priority Hypothesis (IPH) [64] is another explanation proposed to answer why immune quality might not be reflected by sexually dimorphic traits. IPH suggests that a well-functioning body defence is so crucial for long-lived species, like human beings, who are exposed to many ubiquitous pathogens that immunity cannot be traded for the traits that are not directly related to survival (e.g. body height, SHR or HGS). According to IPH, energy resources should be invested in development of costly morphological signals only when the right amount of energy in creating an optimal immune defence is assured. In this instance, masculine traits instead signal a lack of immune related disorders, and an organism’s ability for sparing additional energy for “luxury” sexual dimorphism. This would mean that despite there being no relationship between immune functions themselves and masculine traits, higher masculinization might still provide information about the biological quality of an organism.

The weak positive association between right 2D:4D (which is a better indicator of prenatal androgenisation than left 2D:4D [70] and lymphocyte T count, might suggest that higher prenatal exposure to androgens is related to lymphocyte count in adults. This result can be partially explained by the organizational action of androgens on the immune system. It was shown that exposure to androgens in early life might permanently affect immunity both in primates [71] and rodents [27], whereas gonadectomy in mature animals does not abolish sex-differences in immune response [72]. This does not mean, however, that testosterone level in adults is not related to immunity. There are several experimental and correlational studies showing that testosterone has a negative impact on lymphocyte T count and/or function [10, 73], and that androgens may increase apoptosis of T cells [74]. It is surprising, however, that our observations concern only the lymphocyte count but not lymphocyte function (the proliferative response). It is also worth noting that our result becomes non-significant after adjusting for multiple comparisons and therefore the obtained relationship between the 2D:4D digit ratio and lymphocyte count should be treated with great caution and further studies are warranted. In general, the lack of associations between masculinity markers and immunity in our study is consistent with the results of a recent meta-analysis that provides no support for immunosuppressive testosterone properties in correlational human studies [18].

There are a few limitations of our study. Since we have studied men from a well-nourished Western population (not a common state in our evolutionary past), one needs to be very cautious with generalizing our results to all ecological conditions humans might have lived in. It is also very likely that a well-nourished urbanized population is not ideal for measuring the masculinity-immune associations due to a relatively low cost associated with immune challenges. Improved living conditions, including hygiene practices, infection prevention (vaccines), and increased access to medications and antimicrobial drugs, have all contributed to the reduction of pathogen exposure and shortening the duration of an infection in these populations. Consequently, the physiological cost associated with the immune system functioning in such a population might be much lower in comparison to a population with a greater pathogen load and a higher risk of infection. Furthermore, the effect size (calculated as a Cohen's f2) showed that the magnitude of associations is small or moderate (see Tables 2 and 3), which is also true for a significant relationship between 2D:4D and T cell (f2 = 0.31). This indicates that in well-nourished western populations the relationship between immune parameters and masculine traits is relatively low. In other words, the results suggest that the difference in immune functioning between men with more and less masculine traits might be too low to have functional immunological consequences.

The final problem to consider is that of the complicated structure of immunity and the interdependencies between immunity and other physiological aspects. It is likely that the measurements of baseline immune functions in men who declared no health problems, had no chronic diseases or ongoing infections and had a normal level of inflammatory markers (both CRP and WBC) are still inadequate for measuring immune quality. It is possible that, to assess an individual's immune quality, the analysis of many immune parameters, activated in response to real/natural pathogen-inducing infection, should be taken into account. The measurement of an immunological response to pathogen stimulation might be more informative than baseline immune parameters (in a "healthy state", without antigen stimulation) or only vaccine-induced antibody production or mitogen-induced proliferation.

A Comprehensive Meta‐analysis of the the most commonly used forensic polygraph test, the Comparison Question Test: It can be accurate, experimental studies are generalizable, and no publication bias was detected

A Comprehensive Meta‐analysis of the Comparison Question Polygraph Test. Charles R. Honts  Steven Thurber  Mark Handler. Applied Cognitive Psychology, December 18 2020. https://doi.org/10.1002/acp.3779

Abstract: We conducted a meta‐analysis on the most commonly used forensic polygraph test, the Comparison Question Test. We captured as many studies as possible by using broad inclusion criteria. Data and potential moderators were coded from 138 datasets. The meta‐analytic effect size including inconclusive outcomes was 0.69 [0.66, 0.79]. We found significant moderator effects. Notably, level of motivation had a positive linear relationship with our outcome measures. Information Gain analysis of CQT outcomes representing the median accuracy showed a significant information increase over interpersonal deception detection across almost the complete range of base rates. Our results suggest that the CQT can be accurate, that experimental studies are generalizable, and no publication bias was detected. We discussed the limitations of the field research literature and problems within polygraph profession that lower field accuracy. We suggest some possible solutions.

Science Communication Training: Assessment by Audiences Shows Little Effect, no difference from untrained controls

Assessment by Audiences Shows Little Effect of Science Communication Training. Margaret A. Rubega et al. Science Communication, December 17, 2020. https://doi.org/10.1177/1075547020971639

Abstract: As the science community has recognized the vital role of communicating to the public, science communication training has proliferated. The development of rigorous, comparable approaches to assessment of training has not kept pace. We conducted a fully controlled experiment using a semester-long science communication course, and audience assessment of communicator performance. Evaluators scored the communication competence of trainees and their matched, untrained controls, before and after training. Bayesian analysis of the data showed very small gains in communication skills of trainees, and no difference from untrained controls. High variance in scores suggests little agreement on what constitutes “good” communication.
