Feminist-identified men were substantially more likely to report Erectile Dysfunction Medication use than non-feminist men; could be that feminist men are more honest about this usage, or that non-feminist ones see using it as a threat to masculinity

Silva, Tony, and Tina Fetner. 2022. “Men’s Feminist Identification and Reported Use of Prescription Erectile Dysfunction Medication.” SocArXiv. February 1. doi:10.1080/00224499.2022.2029810

Abstract: We analyzed data from the 2018 Sex in Canada survey (n = 1,015 cisgender men) to examine the association between feminist identification and reported use of prescription ED medication (EDM) during men’s last sexual encounter. Feminist-identified men were substantially more likely to report EDM use than non-feminist men, even after controlling for alcohol use before sex, erection difficulties, sexual arousal, sexual health, mental health, and physical health. One explanation is that feminist men may use EDM to bolster their masculinity when it is otherwise threatened by their identification as feminist. Another is that non-feminist men may be less likely to use prescription EDM because they view accessing healthcare services as a threat to their masculinity. It is also possible that feminist men are more likely to use EDM because they wish to maintain an erection to better please their partner. Lastly, feminist men may be more honest about EDM use than non-feminist men, even though rates are similar. Regardless of the exact reason, therapists can use these results to tailor sexual health messages to clients based on feminist identification. Future work could employ qualitative methods to understand why feminist men report higher rates of EDM use than non-feminist men.

The size and homophily of friendship networks are to a substantial degree based on genetic influence; no evidence found that shared hobbies, education, or Big Five personality traits affect networks

Heritability in friendship networks. Michael Neugart, Selen Yildirim. Journal of Economic Behavior & Organization, Volume 194, February 2022, Pages 41-55. https://doi.org/10.1016/j.jebo.2021.12.008

Highlights

• Heritability of overall friendship network characteristics is explored.

• Data from German TwinLife Study is analyzed within classical twin design.

• Genetic component found in twins’ network size and network homophily.

• Role of twins’ shared hobbies, education, and personality traits is analyzed.

Abstract: There is considerable evidence nowadays that friendship networks account for a large part of an individual’s success or failure in life. Little, however, is known about the extent to which friendship networks are associated with an individual’s genotype. Using data from the German TwinLife study, we explore, within a classical twin design, whether friendship networks are related to genes. We find a substantial heritability component in twins’ network sizes and network homophily, but not in twins’ network closeness. The genetic influence on network characteristics may be attributable to traits which are themselves influenced by genetic factors. Addressing indirect ways in which genes could influence network characteristics, we do not find evidence that shared hobbies, education, or Big Five personality traits affect networks.

Heterosexual women's exposure to a same-sex peer who constituted a sexual rival (straight/bisexual) led to more spreading of reputation-damaging information vs. reputation-enhancing info, compared with exposure to a noncompetitor (lesbian target)

Bakolas, N. K. M., & Park, J. H. (2022). Female intrasexual competition is affected by the sexual orientation of the target and the ovulatory cycle. Evolutionary Behavioral Sciences, Feb 2022. https://doi.org/10.1037/ebs0000287

Abstract: Research suggests that women use indirect aggression strategies to compete with same-sex peers and improve their mating prospects. One such tactic involves strategically transmitting reputation-damaging information as opposed to reputation-enhancing information, to lessen the appeal of sexual rivals. The present study further examined whether this strategic information transmission constitutes an intrasexual competition strategy, by comparing denigration of same-sex peers who constitute sexual competitors or noncompetitors as determined by their sexual orientation. This study also explored the impact of the ovulatory cycle on this strategy, following research suggesting that hormone fluctuation drives subtle behavioral changes near ovulation, amplifying other forms of intrasexual competition between women. Results indicated that among women identifying as straight, exposure to a same-sex peer who constituted a sexual rival (straight/bisexual target) led to greater transmission of reputation-damaging information relative to reputation-enhancing information, compared with exposure to a noncompetitor (lesbian target). The ovulatory cycle was found to be associated with denigration, but this did not depend on the sexuality of the target. Participants in the estimated high-estrogen phase showed greater denigration overall than participants in the low-estrogen phase, regardless of the target’s sexuality.

Women's pick-up lines are perceived as most effective when they are direct and unmistakable, particularly by men

Wade, T. J., Fisher, M. L., & Gaines, L. (2022). The perceived effectiveness of women’s pick-up lines: Do age and personality matter? Evolutionary Behavioral Sciences, Feb 2022. https://doi.org/10.1037/ebs0000286

Abstract: One way to initiate a conversation for the purposes of mate attraction is to use a pick-up line. While past research has addressed men’s use of pick-up lines, there has been far less research on those used by women. Here, we explored the perceived effectiveness of women’s pick-up lines, particularly with regard to one’s age but also as correlated with their Big Five personality factors. We hypothesized that both men and women would rate the same pick-up lines as effective and that older participants would rate pick-up lines as more effective than younger participants. Our results indicate that women’s use of direct pick-up lines, sharing things in common, asking for a phone number, indirectly hinting at a date, and asking if single were perceived as most effective by both sexes. We did not support our prediction about age. The results demonstrate that of the Big Five dimensions, extraversion in particular is important and was positively correlated with perceived effectiveness.

People are more likely to reveal secrets that violate their own moral values; were more willing to reveal immoral secrets as a form of punishment, and this was explained by feelings of moral outrage

Salerno, J. M., & Slepian, M. L. (2022). Morality, punishment, and revealing other people’s secrets. Journal of Personality and Social Psychology, Feb 2022. https://doi.org/10.1037/pspa0000284

Abstract: Nine studies represent the first investigation into when and why people reveal other people’s secrets. Although people keep their own immoral secrets to avoid being punished, we propose that people will be motivated to reveal others’ secrets to punish them for immoral acts. Experimental and correlational methods converge on the finding that people are more likely to reveal secrets that violate their own moral values. Participants were more willing to reveal immoral secrets as a form of punishment, and this was explained by feelings of moral outrage. Using hypothetical scenarios (Studies 1, 3–6), two controversial events in the news (hackers leaking citizens’ private information; Study 2a–2b), and participants’ behavioral choices to keep or reveal thousands of diverse secrets that they learned in their everyday lives (Studies 7–8), we present the first glimpse into when, how often, and one explanation for why people reveal others’ secrets. We found that theories of self-disclosure do not generalize to others’ secrets: Across diverse methodologies, including real decisions to reveal others’ secrets in everyday life, people reveal others’ secrets as punishment in response to moral outrage elicited from others’ secrets.

Handedness in twins: meta-analyses

Handedness in twins: meta-analyses. Lena Sophie Pfeifer, Judith Schmitz, Marietta Papadatou-Pastou, Jutta Peterburs, Silvia Paracchini & Sebastian Ocklenburg. BMC Psychology volume 10, Article number: 11. Jan 15 2022. https://bmcpsychology.biomedcentral.com/articles/10.1186/s40359-021-00695-3

Abstract

Background: In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii) monozygotic compared to dizygotic twins. Moreover, (iii) studies have shown a higher rate of handedness concordance in monozygotic compared to dizygotic twins, in line with genetic factors playing a role for handedness.

Methods: By means of a systematic review, we identified 59 studies from previous literature and performed three sets of random effects meta-analyses on (i) twin-to-singleton Odds Ratios (21 studies, n = 189,422 individuals) and (ii) monozygotic-to-dizygotic twin Odds Ratios (48 studies, n = 63,295 individuals), both times for prevalence of left-, mixed-, and non-right-handedness. For monozygotic and dizygotic twin pairs we compared (iii) handedness concordance Odds Ratios (44 studies, n = 36,217 twin pairs). We also tested for potential effects of moderating variables, such as sex, age, the method used to assess handedness, and the twins’ zygosity.

Results: We found (i) evidence for higher prevalence of left- (Odds Ratio = 1.40, 95% Confidence Interval = [1.26, 1.57]) and non-right- (Odds Ratio = 1.36, 95% Confidence Interval = [1.22, 1.52]), but not mixed-handedness (Odds Ratio = 1.08, 95% Confidence Interval = [0.52, 2.27]) among twins compared to singletons. We further showed a decrease in Odds Ratios in more recent studies (post-1975: Odds Ratio = 1.30, 95% Confidence Interval = [1.17, 1.45]) compared to earlier studies (pre-1975: Odds Ratio = 1.90, 95% Confidence Interval = [1.59–2.27]). While there was (ii) no difference between monozygotic and dizygotic twins regarding prevalence of left- (Odds Ratio = 0.98, 95% Confidence Interval = [0.89, 1.07]), mixed- (Odds Ratio = 0.96, 95% Confidence Interval = [0.46, 1.99]), or non-right-handedness (Odds Ratio = 1.01, 95% Confidence Interval = [0.91, 1.12]), we found that (iii) handedness concordance was elevated among monozygotic compared to dizygotic twin pairs (Odds Ratio = 1.11, 95% Confidence Interval = [1.06, 1.18]). By means of moderator analyses, we did not find evidence for effects of potentially confounding variables.

Conclusion: We provide the largest and most comprehensive meta-analysis on handedness in twins. Although a raw, unadjusted analysis found a higher prevalence of left- and non-right-, but not mixed-handedness among twins compared to singletons, left-handedness was substantially more prevalent in earlier than in more recent studies. The single large, recent study which included birth weight, Apgar score and gestational age as covariates found no twin-singleton difference in handedness rate, but these covariates could not be included in the present meta-analysis. Together, the secular shift and the influence of covariates probably make it unsafe to conclude that twinning has a genuine relationship to handedness.

Discussion

In three sets of meta-analyses, we examined the influence of twin status and twin zygosity on handedness prevalence and handedness concordance. Our first set of meta-analyses confirmed that in line with Sicotte et al. [10], left-handedness (OR = 1.40, Fig. 3) and non-right-handedness (OR = 1.36, Fig. 5) occur more often among twins than among singletons. Moderator analyses found elevated levels of non-right-handedness among twins to be independent of all variables tested with respect to a potential moderating effect. However, we found that more recent studies reported smaller differences in prevalence of left-handedness between twins and singletons (Fig. 6). To test whether there is a higher left-handedness prevalence in twins compared to singletons in more recent studies at all, we estimated twin-to-singleton ORs for left-handedness for studies published pre and post 1975 separately. With a pre-1975 OR of 1.90 (95% CI = [1.59, 2.27]) and a post-1975 OR of 1.30 (95% CI = [1.17, 1.45]), ORs for more recent studies were smaller, but still indicated a significant twin effect on left-handedness.

Overall, the decrease in twin-to-singleton ORs might either be explained by a decrease in left-handedness in twins or an increase of left-handedness in singletons, or both. As already mentioned, complications occur more often in the course of multiple births [11,12,13], which might contribute to the development of atypical handedness [10]. However, most individual studies included in our meta-analysis did not provide information on pre- or perinatal conditions, so we could not test for a moderating effect of these conditions on the twin-to-singleton OR. Along these lines, future research might have a closer look on the relation between birth complications and handedness.

Assuming that higher proportions of left-handedness among twins might be the by-product of birth complications, a decrease in atypical handedness in twins must be assigned to a decrease in the occurrence of these complications. In fact, it is well conceivable that medical progress over the last decades, that is clearly detectable, e.g. in the United States [92, 93], may have helped to equalize the risks associated with multiple and single births. Such assumptions are supported by a study by Heikkilä et al. [77] who showed differences in left-handedness in twins and singletons to disappear when controlling for birth weight, Apgar score, and gestational age. We therefore tested whether there is evidence for a decrease in left-handedness prevalence in twins (Fig. 6b) by running meta-analyses on left-handedness prevalence in twins and singletons separately while including publication year as a moderator variable. However, while there was no evidence for an effect of publication year on left-handedness prevalence in twins, there seemed to be a trend towards an increase of left-handedness prevalence in singletons (Fig. 6c).

The overall prevalence of atypical handedness in our study was lower than expected. We found 9.13% of twins and 6.97% of singletons to be left-handed (Table 1), while Papadatou-Pastou et al. [3] reported a figure of 10.6% (95% CI 9.71%, 11.50%) for the general population. The low values in our study might be the result of a general effect of publication year in singletons, given that the prevalence of left-handedness has been shown to be higher in younger than in older cohorts [25, 94, 95]. The social stigma associated with left-handedness in the last century [96] may have driven left-handers to conceal their preference in self-reports [97] and to retrain to use their right hand [25, 98]. Most of the studies included in our meta-analysis were published in the previous century and their participants could have been subjected to environmental pressures against left-handedness, leading to underestimation of the true population prevalence of left-handedness. Similarly, we found low overall prevalence of mixed-handedness (3.39% in twins and 2.67% in singletons, Table 1), whereas Papadatou-Pastou et al. [3] gave a point estimate of 9.3% for the general population. This might also be due to an effect of publication year. Moreover, three of five studies that provided data for mixed-handedness classified handedness as writing hand so that data extracted from these studies most likely reflect not mixed-handedness, but ambidexterity, which is much rarer [99].

Our second set of meta-analyses found no difference in the prevalence of atypical handedness between MZ and DZ twins (left-handedness OR = 0.98, mixed-handedness OR = 0.96, non-right-handedness OR = 1.01, Table 3). This result is consistent with the meta-analysis by Sicotte et al. [10] who interpreted this null-effect as indication against mirror imaging theories designed to explain heightened frequencies of left-handers and frequent handedness discordance among MZ twins [100,101,102]. Indeed, it weakens the hypothesis suggesting that the monozygotic twinning process is responsible for atypical handedness [10]. Moreover, it indicates that the overall heightened frequencies of left- and non-right-handers among twins are independent of the twins’ zygosity. A moderator analysis showed that this effect was not influenced by the method used to determine the twins’ zygosity, thus refuting the idea that the result was affected by the accuracy with which twins were classified as monozygotic or dizygotic. All in all, revealing comparable prevalence of atypical handedness for MZ and DZ twins cannot enrichen knowledge about genetic contribution to handedness per se. As already recognized by Sicotte et al. [10], to do so, it is crucial to look at pairwise handedness concordance or discordance of MZ and DZ twin pairs.

Our third set of meta-analyses found a small yet significant effect (OR = 1.11, Fig. 7) for higher handedness concordance among MZ (80.49%) as compared to DZ (79.27%) twins, consistent with the meta-analysis by Sicotte et al. [10]. Even though other publications have demonstrated the occurrence of handedness discordance among MZ twin pairs [100, 101, 103, 104], it was estimated to concern a minority of 20–25% of cases [2]. Stronger phenotypic variation among DZ compared to MZ pairs indicates a certain genetic foundation of that phenotype [2, 26]. Therefore, our results confirm handedness to rely on genetic factors to some extent [10] and are consistent with heritability estimates of 0.24–0.26 [31,32,33]. A moderator analysis suggested that the frequencies of handedness concordance did not differ between studies included in the meta-analysis by Sicotte et al. [10], studies explicitly excluded from Sicotte et al. [10], and more recent studies.

To allow future meta-analyses to perform comparisons on handedness prevalence in twins more specifically (e.g., handedness in male vs. female twins, or handedness in same sex pairs vs. opposite sex pairs), it is desirable that researchers report results broken down for parameters like zygosity, sex, and consider data on birth complications. As this might be beyond the scope of individual papers, we encourage authors to provide open raw data in publicly accessible repositories such as the osf.io.

The present study is not without limitations. We did not investigate relative hand skill but were restricted to hand preference. Measuring hand preference is far more established as compared to assessing relative hand skill, as it is easier and more convenient [105]. Most of the studies included in our meta-analysis only provided information on hand preference, not allowing for an additional analysis for hand skill. Moreover, hand preference and hand skill correlate to some extent [106,107,108], and the distribution of handedness categories overlaps for preference- and skill-related criterions in 90% of the cases [109].

Similarly, our study only dealt with handedness direction in terms of categorial handedness classification which does not take into account the fact that individual handedness can further be defined regarding its strength or its degree. Along these lines, other approaches consider handedness as a continuum, extending the question to how strong or how consistently one hand is preferred, used, or skilled over the other. Indeed, several findings obtained within laterality research on associations between handedness and structural brain lateralization [110] or cognitive performance [111, 112] as well as concerning the genetic foundation of handedness [113, 114] are linked to strength but not direction of handedness. However, since most studies included in the present meta-analyses did not assess handedness in a continuous manner, we were unable to account for handedness strength. Therefore, it falls to future studies to extend their assessment repertoire by measures of handedness strength.

From a methodological point of view, it is further crucial to mention that overall, our moderator analyses are low in power due to the investigated study sample sizes. Of note, in some cases, moderator levels included only three data points calling for an interpretation of these findings with caution.

Meta-analysis: People do not drink alcohol to drown their sorrows, but to indulge in their joys

Dora, Jonas, Marilyn Piccirillo, Katherine T. Foster, Kelly Arbeau, Stephen Armeli, Marc Auriacombe, Bruce D. Bartholow, et al. 2022. “The Daily Association Between Affect and Alcohol Use: A Meta-analysis of Individual Participant Data.” PsyArXiv. February 1. psyarxiv.com/xevct

Abstract: Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess affect and the number of alcoholic drinks consumed. Results indicate that people do not drink more often on days they experience high negative affect, but are more likely to drink and drink heavily on days high in positive affect. People self-reporting a motivational tendency to drink-to-cope and drink-to-enhance were estimated to consume more alcohol, but not to consume more alcohol on days they experience higher negative and positive affect. Results were robust across different operationalizations of affect, study designs, study populations, and individual characteristics. Based on our findings, we collectively propose an agenda for future research to explore open questions surrounding affect and alcohol use.

Age, gender, geographical region, belonging to the host country, religious fractionalization, & stereotypic gender roles (proxied by labor force participation rate of women in the athlete’s country) are prominent predictors of crying in the Olympics

Golden tears: A cross-country study of crying in the Olympics. Alex Krumer, Andrew Musau. January 2022. https://www.researchgate.net/publication/358233754_Golden_tears_A_cross-country_study_of_crying_in_the_Olympics

Description: Previous psychological studies on emotional crying have overwhelmingly relied on self-reported data from individuals’ recollections of their own experiences. Apart from the bias that arises from faulty recollection, there is no incentive for an individual to truthfully reveal his or her own experiences in such surveys. In this paper, we address the methodological limitations associated with self-reporting and non-sufficient emotional elicitors, by exploring data on gold medalists of all 450 individual events at the 2012 and 2016 Summer Olympic Games at the end of the medalists’ respective competitions and during the medal ceremonies. We find that age, gender, geographical region, belonging to the host country, religious fractionalization, and stereotypic gender roles (proxied by labor force participation rate of women in the athlete’s home country) are likely to be prominent predictors of crying. Thus, our results suggest that emotional crying is not only a biological feature, but also a cultural phenomenon.

Social acceptance & social anxiety, embarrassment, jealousy, hurt feelings, guilt, & lowered self-esteem: We may do distance ourselves from other people, aggress rejecters, or engage in symbolic efforts to increase subjective acceptance

The relentless pursuit of acceptance and belonging. Mark R. Keary, Shira Gabriel. Advances in Motivation Science, January 31 2022. https://doi.org/10.1016/bs.adms.2021.12.001

Abstract: A great deal of human behavior is motivated by the desire for acceptance and belonging, and a high proportion of people's emotional reactions stems from concerns with actual or potential social rejection. The pervasive quest for acceptance can be seen in the attention and effort people devote to their physical appearance, their efforts to be liked, achievement-related behaviors, conformity, accumulating resources that others need, and generally being the sort of person with whom others want to have social connections. Depending on the context, concerns with social acceptance are typically accompanied by emotions such as social anxiety, embarrassment, jealousy, hurt feelings, and guilt, as well as lowered self-esteem. In addition, people who feel inadequately valued and accepted may behave in ways to increase acceptance, aggress against those who rejected them, distance themselves from other people, and/or engage in symbolic efforts to increase their subjective sense of being accepted. Concerns with acceptance and belonging exert a pervasive, ongoing effect on human thought, behavior, and emotion.

COVID-19 state anxiety is linked to everyday cognition and slower processing speed in women, but not men

COVID-19-Related Anxiety and Cognition in Middle-Aged and Older Adults: Examining Sex as a Moderator. Ashley F. Curtis et al. Psychological Reports, January 31, 2022. https://doi.org/10.1177/00332941211064820

Abstract: Aging populations experience disproportionate risk for cognitive decline, which may be exacerbated by coronavirus (COVID-19) illness, particularly among women. This study tested sex as a moderator of associations between COVID-19 state anxiety and cognition in middle-aged/older adults. Adults aged 50+ (N = 275; 151 men/124 women) completed the Coronavirus Anxiety Scale and Cognitive Failures Questionnaire online from remote locations in July/August 2020. A subset of participants (n = 62) completed an objective cognitive task (Stroop). Multiple regressions determined whether sex moderated associations between COVID-19 anxiety and cognitive outcomes. Sex was a significant moderator, such that for women (not men), greater COVID-19 anxiety was associated with more memory failures and blunders (subjective measures) and worse processing speed (objective measure). COVID-19 state anxiety is linked to everyday cognition and processing speed in women, but not men. Consistency across subjective and objective measures promotes the need for sex-specific understanding of the pandemic’s behavioral and cognitive effects in mid-to-late life.

37% of the participants contacted other persons because they dreamed about them; dream recall frequency, attitude towards dreaming, younger age, and female gender was associated with contacting the person(s) dreamed of

The Frequency of Contacting Persons you Dreamed About: A Social Aspect of Dreaming. Michael Schredl, Anja S. Göritz. Imagination, Cognition and Personality, January 31, 2022. https://doi.org/10.1177/02762366221077631

Abstract: Although dreams are very private, dreaming has also social components, i.e., dreams are shared quite often. We studied the frequency of how often the dreamer deliberately contacted another person because s/he dreamed about this person, as this might intensify the waking-life bonds with this person. Overall, 2929 participants completed the dream survey, and a subsample also completed a Big Five Personality inventory. The findings indicate that 37% of the participants contacted other persons because they dreamed about them. Dream recall frequency, attitude towards dreaming, younger age, and female gender was associated with contacting the person(s) dreamed of. Moreover, extraversion was also related to the frequency of contacting the person(s) dreamed of – similar to the relationship found for dream sharing frequency and extraversion. However, the association with low conscientiousness is a new finding. It would be very interesting to test whether this social behavior (contacting another person) motivated by dreams strengthens the social bonds between the dreamer and the contacted person(s) and thereby provide support for the Social Simulation Theory.

A Free-Market Environmentalist Transition toward Renewable Energy: The Cases of Germany, Denmark, and the United Kingdom

A Free-Market Environmentalist Transition toward Renewable Energy: The Cases of Germany, Denmark, and the United Kingdom. William Hongsong Wang, Vicente Moreno-Casas, Jesús Huerta de Soto. Energies 2021, 14(15), 4659; July 31 2021. https://doi.org/10.3390/en14154659

Abstract: Renewable energy (RE) is one of the most popular public policy orientations worldwide. Compared to some other countries and continents, Europe has gained an early awareness of energy and environmental problems in general. At the theoretical level, free-market environmentalism indicates that based on the principle of private property rights, with fewer state interventionist and regulation policies, entrepreneurs, as the driving force of the market economy, can provide better services to meet the necessity of offering RE to protect the environment more effectively. Previous studies have revealed that Germany, Denmark, and the United Kingdom have made some progress in using the market to develop RE. However, this research did not analyze the three countries’ RE conditions from the perspective of free-market environmentalism. Based on our review of the principles of free-market environmentalism, this paper originally provides an empirical study of how Germany, Denmark, and the United Kingdom have partly conducted free-market-oriented policies to successfully achieve their policy goal of RE since the 1990s on a practical level. In particular, compared with Germany and Denmark, the UK has maintained a relatively low energy tax rate and opted for more pro-market measures since the Hayekian-Thatcherism free-market reform of 1979. The paper also discovers that Fredrich A. Hayek’s theories have strongly impacted its energy liberalization reform agenda since then. Low taxes on the energy industry and electricity have alleviated the burden on the electricity enterprises and consumers in the UK. Moreover, the empirical results above show that the energy enterprises play essential roles in providing better and more affordable RE for household and industrial users in the three sampled countries. Based on the above results, the paper also warns that state intervention policies such as taxation, state subsidies, and industrial access restrictions can impede these three countries’ RE targets. Additionally, our research provides reform agendas and policy suggestions to policymakers on the importance of implementing free-market environmentalism to provide more efficient RE in the post-COVID-19 era.

5. Conclusions

Based on the review of the theoretical principles of free-market environmentalism, this paper has originally provided an empirical study of how Germany, Denmark, and the UK partly conduct free-market-oriented policies to successfully achieve their policy goal of broader use of RE since the 1990s.

The paper’s empirical results show that in 28 years, from 1990 to 2018, all three countries have shown positive features in their respective RE transitions. This tendency is especially evident for the increasing trend in the share of RE in gross electricity production and gross available energy and the decreasing trend in GHG emissions. However, as the supply of RE increased, the prices of electricity in the three countries did not show the same downward trend. This result alters the traditional view on these countries’ energy transitions, with the UK being more successful in a critical aspect of any energy transition: affordability.

Simultaneously, by measuring the specific data on taxation, state subsidies, and industrial access restrictions in the three sampled countries, we pointed out how these interventionist and regulation policies have caused damage to the three countries’ RE transition goals. Given free-market environmentalism, the cases of Germany and Denmark serve to illustrate how vital the entrepreneurship-based bottom-up forces (led by organizations and entrepreneurs in the form of RE cooperatives) are for the relative success of an energy transition. The German experience emphasizes political decentralization for decision-making and a certain freedom in the RE market. Inside this framework, a wide range of decentralized initiatives still thrive. This policy is the reason for the country’s energy transition success. However, there are distorting effects of government intervention, such as high electricity prices. They are caused by taxes, subsidies, and industry access restrictions. In general, Germany’s energy prices are not entirely market-oriented but are taxed and subsidized by the German government. As we have pointed out above, Germany’s energy prices are artificially high due to the FIT system. Therefore, Germany cannot be considered an ideal sample of free-market environmentalism. As previous research indicated, we also suggest Germany reduce the degrees of the above three interventionist policies as best as possible to enhance RE production and reduce electricity and RE prices.

Like the German case, the Danish energy policy has not wholly followed the principles of free-market environmentalism due to taxes, subsidies, and industry access restrictions. Denmark’s high electricity prices are due to high production costs and high taxes. As a result, Denmark faces a tough challenge to achieve an efficient and affordable RE transition concerning electricity prices. As previous research indicated, we also suggest Denmark should conduct tax reduction for its RE industry and eliminate state subsidies and industry access restrictions. However, despite the above policy deficiencies, Denmark is managing a RE transition due to the essential roles of decentralized local organizations and entrepreneurial activities. Moreover, more market-based RE innovation has created more jobs and reduced more GHG emissions since 1990. Even the literature that was not in favor of free-market environmentalism also acknowledged the Danish success in RE transition and its community and entrepreneurship-based characters [23].

On the other hand, compared with Germany and Denmark, the UK has maintained a relatively low energy tax rate and opted for more pro-market measures since the Hayekian-Thatcherism free-market reform of 1979. Fredrich A. Hayek’s theories have strongly impacted its energy liberalization reform agenda since then. Low taxes on the energy industry and electricity have alleviated the burden on electricity enterprises and consumers. Electricity prices have remained relatively low since 1990. However, interventionist policies such as state-regulated auctions and industry access restrictions have obstructed its energy transition. Moreover, RE policies are not as decentralized as Germany and Denmark, although RE innovation has increased in the three countries. Despite not having a purely free-market environmentalist energy policy, the UK has come closer to free-market environmentalism than the other two countries. Contrary to what some literature posits, the UK is achieving energy transition at a good pace, even beating Germany and Denmark by containing the rise in electricity prices. Therefore, with less intervention in the future, a better conducted RE market process could provide better conditions for British RE development.

Thus, during the post-COVID-19 era, to attain economic recovery and achieve a more advanced level of RE and protect the environment, it is essential to respect the principles of private property rights and free-market price coordination to acquire more and better RE. Hence, EU policymakers should adopt its RE policy from the perspective of free-market environmentalism to conduct better entrepreneurship for RE. Government RE’s intervention-regulation policies such as taxation, subsidies, and industry restrictions infringe on private property rights and cause economic discoordination and zero-sum games. Moreover, although the UK has not been an EU member since Brexit, its precious and successful experience of energy liberalization since the 1979 Hayekian-Thatcherism free-market energy reform could help other European countries to achieve better RE production and affordable energy prices. The UK experience and the free-market environmentalist policies that Germany and Denmark conduct could help other countries globally. Additionally, the empirical results in this paper show that the result of free-market environmentalism should be implemented over a long period. Policymakers should perceive that the free-market environmentalist policy approach and the entrepreneurial production of RE take time. Any interventionist eager for quick success may reverse the policy results. Hence, respecting entrepreneurship and reducing state intervention or regulation as much as possible is what global policymakers should execute during the post-COVID-19 era for a better energy transition.

Girls learn faster than boys when school is out (in both reading and math), but this advantage is completely eliminated when school is in session; schools act as a relatively standardizing institution, producing more similar patterns in learning

Schools as a Relatively Standardizing Institution: The Case of Gender Gaps in Cognitive Skills. Douglas B. Downey, Megan Kuhfeld, Margriet van Hek. Sociology of Education, January 27, 2022. https://doi.org/10.1177/00380407211070319

Abstract: Growing evidence suggests that contrary to popular belief, schools mostly do not generate achievement gaps in cognitive skills but, rather, reflect the inequalities that already exist. In the case of socioeconomic status, exposure to school often reduces gaps. Surprisingly little is known, however, about whether this pattern extends to gender gaps in cognitive skills. We compare how gender gaps in math and reading change when children are in school versus out (in the summer) among over 900,000 U.S. children. We find that girls learn faster than boys when school is out (in both reading and math), but this advantage is completely eliminated when school is in session. Compared to the family environment, schools act as a relatively standardizing institution, producing more similar gendered patterns in learning.

Both facemasks and makeup tend to result in over-estimation of the young women's age compared to neutral faces, but the combination of both is not additive: 4 years on average

Your ID, please? The effect of Facemasks and Makeup on Perceptions of Age of Young Adult Female Faces. H. Davis, J. Attard-Johnson. Applied Cognitive Psychology, January 28 2022. https://doi.org/10.1002/acp.3923

Abstract: During the COVID-19 pandemic, wearing facemasks was mandatory in the United Kingdom except for individuals with medical exemptions. Facemasks cover the full lower half of the face, however the effect of facemasks on age perception is not yet known. The present study examined whether age estimation accuracy of unfamiliar young adult women is impaired when the target is wearing a facemask. This study also examined whether makeup, which has previously been shown to increase error bias, further impairs age estimation accuracy when paired with a facemask. The findings indicate that both facemasks and makeup tend to result in over-estimation of the young women's age compared to neutral faces, but the combination of both is not additive. Individual level analysis also revealed large individual differences in age estimation accuracy ranging from estimates within 1 year of the target's actual age, and age estimates which deviated by up to 20 years.

Does the Mafia Hire Good Accountants?

Bianchi, Pietro A. and Bianchi, Pietro A. and Francis, Jere R. and Marra, Antonio and Pecchiari, Nicola, Does the Mafia Hire Good Accountants? (November 5, 2021). SSRN: http://dx.doi.org/10.2139/ssrn.3957650

Abstract: We investigate if organized crime groups (OCG) are able to hire good accountants. We use data about criminal records to identify Italian accountants with connections to OCG. While the work accountants do for the OCG ecosystem is not observable, we can determine if OCG hire “good” accountants by assessing the overall quality of their work as external monitors of legal businesses. We find that firms serviced by accountants with OCG connections have higher quality audited financial statements compared to a control group of firms serviced by accountants with no OCG connections. The findings provide evidence OCG are able to hire good accountants, despite the downside risk of OCG associations. Results are robust to controls for self-selection, for other determinants of auditor expertise, direct connections of directors and shareholders to OCG, and corporate governance mechanisms that might influence auditor choice and audit quality.

Rodent-hunting cat ownership in childhood was associated with higher psychotic experience scores in male participants, but not in female participants

Conditional associations between childhood cat ownership and psychotic experiences in adulthood: A retrospective study. Vincent Paquin et al. Journal of Psychiatric Research, Jan 30 2022. https://doi.org/10.1016/j.jpsychires.2022.01.058

Abstract: Ownership of cats in childhood has been inconsistently associated with psychosis in adulthood. Parasitic exposure, the putative mechanism of this association, may be more common with rodent-hunting cats, and its association with psychosis may depend on other environmental exposures. We examined the conditional associations between childhood cat ownership and the frequency of psychotic experiences in adulthood. Adults (n = 2206) were recruited in downtown Montreal to complete a survey about childhood cat ownership (non-hunting or rodent-hunting), winter birth, residential moves in childhood, head trauma history, and tobacco smoking. The frequency of psychotic experiences (PE) was measured with the 15-item positive subscale of the Community Assessment of Psychic Experiences. Associations between exposures and PE were examined in linear regressions adjusted for age and sex. Interactions among variables were explored using a conditional inference tree. Rodent-hunting cat ownership was associated with higher PE scores in male participants (vs. non-hunting or no cat ownership: SMD = 0.57; 95% CI: 0.27, 0.86), but not in female participants (SMD = 0.10; 95% CI: −0.18, 0.38). In the conditional inference tree, the highest mean PE score was in the class comprised of non-smokers with >1 residential move, head trauma history, and rodent-hunting cat ownership (n = 22; mean standard score = 0.96). The interaction between rodent-hunting cat ownership and head trauma history was supported by a post-hoc linear regression model. Our findings suggest childhood cat ownership has conditional associations with psychotic experiences in adulthood.

Gender Diffs in Childhood Trauma, Schizotypy, Negative Emotions: Cognitive Disorganisation (poor attention, concentration, decision-making, social cognition) positively corrs w/physical neglect & sexual abuse as children in women, no links among men

Thomas, Elizabeth H.X., Susan L. Rossell, and Caroline Gurvich. 2022. "Gender Differences in the Correlations between Childhood Trauma, Schizotypy and Negative Emotions in Non-Clinical Individuals" Brain Sciences 12, no. 2: 186. Jan 29 2022. https://doi.org/10.3390/brainsci12020186

Abstract: Early life trauma has a negative impact on the developing brain, and this can lead to a wide range of mental illnesses later in life. Childhood trauma is associated with increased psychotic symptoms and negative emotions such as depressive, anxiety, and stress symptoms in adulthood. Childhood trauma has also been shown to influence sub-clinical ‘schizotypy’ characteristics of psychosis in the general population. As it has been reported that mental health outcomes after early life trauma exposure are influenced by gender, the current study aimed to investigate the gender differences in the relationship between childhood trauma, schizotypy and negative emotions. Sixty-one non-clinical participants (33 men and 28 women) aged between 18 and 45 completed self-report questionnaires to measure early life trauma, schizotypy and negative emotions. Despite similar levels of childhood trauma in men and women, early life trauma in women was associated with increased schizotypy personality characteristics (Cognitive Disorganisation) and increased depression, anxiety and stress later in life, but no correlations were observed in men. Our findings suggest that the sociocultural and biological processes affected by early life adversities may differ between the genders. Women may be more vulnerable to the influence of childhood trauma, which may be associated with increased psychopathology later in life.

Risk Perception and Behaviour Change, COVID-19: Socializing rebounded after partial vaccination; after full vaccination, communal activities recovered; however, the propensity for protective behaviours declined

Jia, Jayson S., Yun Yuan, Jianmin Jia, and Nicholas Christakis. 2022. “Risk Perception and Behaviour Change After Personal Vaccination for COVID-19 in the USA.” PsyArXiv. January 30. psyarxiv.com/afyv8

Abstract: Although vaccines are crucial for giving pandemic-stricken societies the confidence to return to socioeconomic normalcy, vaccination may also induce laxity in personal protective behaviours (e.g., handwashing, facemask use). We use the quasi-experimental context of the COVID-19 vaccine rollout across the United States to quantify the impact of different stages of personal vaccination on people’s risk perceptions, daily activities, and risk mitigation behaviours, which we measure in a three-wave national panel study (N wave-1 = 7,358, N wave-2 = 3,000, N wave-3 = 2,345) from March to June, 2021, and validate using vaccination, infection, and human mobility data. Socializing rebounded after only partial vaccination. After full vaccination, communal activities recovered; however, the propensity for protective behaviours declined. The effects were heterogenous depending on vaccination level, demographics, and infection history. We further use a utility theory framework to model risk-value trade-offs and risk-construction for different behaviours.

Rolf Degen summarizing... The sport science and coaching community is very susceptible to pseudoscientific bullshit

Stoszkowski, John, Shane Littrell, and Dave Collins. 2022. “Cutting the Crap: The Perceived Prevalence of Pseudoscientific Bullshit in Sport Science and Coaching.”PsyArXiv. January 29 2022. https://psyarxiv.com/7t2my/

Abstract: Recent literature has identified and examined the construct of bullshit as a notable threat to the promulgation and use of accurate information. The parallel challenges posed by increasing availability of unfiltered online information have been identified as further exacerbating factors. Accordingly, the present paper adds to this perspective by examining susceptibility to and perceived frequency of bullshit in the sport science and coaching domain. Participants (N = 280) completed several validated instruments examining susceptibility, tendency to engage in and perceived experience of bullshit in their professional environments. Data suggest similar ratings to more general population samples, with educational level acting as a key moderating factor. Implications for practice and psychosocial approaches to bullshit are discussed, in tandem with recommendations for refinements to communication.

Why men are the main COVID-19 transmitters: Despite no observed differences in viral load in nasopharyngeal samples, adult males showed a significantly higher viral load in saliva samples than adult women; plus men have higher aerosol emissions

Men are the main COVID-19 transmitters: behavior or biology? Monize V. R. Silva, Mateus V. de Castro, Maria Rita Passos-Bueno, Paulo A. Otto, Michel S. Naslavsky & Mayana Zatz. Discover Mental Health volume 2, Article number: 1, 2022. Jan 24 2022. https://link.springer.com/article/10.1007/s44192-022-00004-3

Abstract

Background: COVID-19 has affected millions of people worldwide. Clinical manifestations range from severe cases with lethal outcome to mild or asymptomatic cases. Although the proportion of infected individuals does not differ between sexes, men are more susceptible to severe COVID-19, with a higher risk of death than women. Also, men are pointed out as more lax regarding protective measures, mask wearing and vaccination. Thus, we questioned whether sex-bias may be explained by biological pathways and/or behavioral aspects or both.

Methods: Between July 2020 and July 2021, we performed an epidemiological survey including 1744 unvaccinated adult Brazilian couples, with there was at least one infected symptomatic member, who were living together during the COVID-19 infection without protective measures. Presence or absence of infection was confirmed by RT-PCR and/or serology results. Couples were divided into two groups: (1) both partners were infected (concordant couples) and (2) one partner was infected and the spouse remained asymptomatic despite the close contact with the COVID-19 symptomatic partner (discordant couples). Statistical analysis of the collected data was performed aiming to verify a differential transmission potential between genders in couples keeping contact without protective measures.

Results: The combination of our collected data showed that the man is the first (or the only) affected member in most cases when compared to women and that this difference may be explained by biological and behavioral factors.

Conclusions: The present study confirmed the existence of gender differences not only for susceptibility to infection and resistance to COVID-19 but also in its transmission rate.

Discussion

All the results obtained in the present study strongly suggest that males are not only more susceptible to COVID-19 severity, as shown in worldwide epidemiological surveys, but they are also more likely to transmit the virus to their partners when compared to females in the household transmission context. The epidemiological findings in the present survey are consistent with the results of other published studies involving couples where one of the partners was infected by their spouses [40, 41]. Female individuals aged between 17 and 65 years were also frequently found to be secondary cases [41].

Aiming to analyze a more homogeneous cohort and since age is an important predictor of severity and risk of death by COVID-19, we focused our survey on couples of comparable ages and economic status and therefore similar access to health care. It is also important to note that the survey was performed before the vaccination was started.

One of the possible current biological hypotheses for such gender variable transmission rate is a differential viral load in saliva, which has been explored as an important clinical measure of disease severity due to its positive association with many COVID-19 inflammatory markers [42]. These factors, together with the higher adoption of hygiene and protective measures among females, may justify the lower transmission rates in this group.

Interestingly, in a recent study of our group [43] it was observed that, although there were no observed gender differences in viral load in nasopharyngeal samples, adult males showed a significantly higher viral load in saliva samples (verified by RT-LAMP viral testing) than adult women.

These observations, together with the evidence of higher aerosol emission by men which makes them more likely to be “superspreaders” than women, support the hypothesis that male individuals are more efficient virus transmitters than females, which is related to biological and behavioral aspects.

This study has some limitations regarding the relatively modest number of couples included in the present cohort when compared with other epidemiological surveys of in-house transmission [40, 41]. Additionally, the couples who responded the questionnaire are on average younger than the mean age of the population since, in Brazil, younger people have more access and familiarity with internet than older adults [44]. Nevertheless, our study brings new knowledge to the field of public health regarding SARS-CoV-2 transmission dynamics.

In short, the present study confirmed the existence of gender differences not only for susceptibility to infection and resistance to COVID-19 but also in the transmission rate.
