From 2018... If all acts of love and pleasure are Her rituals, what about BDSM? Feminist culture wars in contemporary Paganism

From 2018... If all acts of love and pleasure are Her rituals, what about BDSM? Feminist culture wars in contemporary Paganism. Michelle Mueller. Theology & Sexuality, Volume 24, 2018, Issue 1, Jun 20 2017, http://www.tandfonline.com/10.1080/13558358.2017.1339930

Abstract: Since the 1970s, some religious practitioners of the contemporary Pagan movement (a.k.a. Neo-Paganism) have embraced spiritual BDSM, or “sacred kink,” as a spiritual discipline relating to their tradition. The “sex wars,” debates around pornography, prostitution, and sadomasochism, have appeared in the history of Wicca and contemporary Paganism. Pagan feminists have brought theological questions to the same debates. They have focused on the Wiccan Rede (“harm none”) and the affirmation of pleasure in Doreen Valiente’s Charge of the Goddess that states that, “All acts of pleasure are [the Goddess’s] rituals.” While support for BDSM has become the dominant public perspective in twenty-first century Paganism, the movement’s late twentieth-century history includes instances of anguish as individuals wrestled with their personal sexual desire and their feminist principles.

Appetite for destruction: Counterintuitive effects of attractive faces on people's food choices

Appetite for destruction: Counterintuitive effects of attractive faces on people's food choices. Tobias Otterbring. Psychology & Marketing, August 24 2019. https://doi.org/10.1002/mar.21257

Abstract: Faces in general and attractive faces, in particular, are frequently used in marketing, advertising, and packaging design. However, few studies have examined the effects of attractive faces on people's choice behavior. The present research examines whether attractive (vs. unattractive) faces increase individuals’ inclination to choose either healthy or unhealthy foods. In contrast to the beliefs held by most marketing professors, but consistent with visceral state theories, exposure to attractive (vs. unattractive) opposite‐sex faces increased choice likelihood of unhealthy foods. This effect was moderated by self‐view‐relevant attributes and exerted a particularly powerful influence on individuals who were single (vs. in a relationship) and individuals rating themselves as unattractive (vs. attractive). Furthermore, the effect was mediated by arousal, was stronger for men than for women, but did not generalize after exposure to attractive (vs. unattractive) same‐sex faces. As pictorial exposure is sufficient for the effect to occur, these findings have important implications for marketing, advertising, and public health.

Those with tattoos, especially visible ones, are more short-sighted in time preferences & more impulsive than the non-tattooed; almost nothing mitigates these results

Tat will tell: Tattoos and time preferences. Bradley J. Ruffle, Anne E. Wilson. Journal of Economic Behavior & Organization, August 24 2019. https://doi.org/10.1016/j.jebo.2019.08.001

Abstract: Survey and experimental evidence documents discrimination against tattooed individuals in the labor market and in commercial transactions. Thus, individuals’ decision to get tattooed may reflect short-sighted time preferences. We show that, according to numerous measures, those with tattoos, especially visible ones, are more short-sighted and impulsive than the non-tattooed. Almost nothing mitigates these results, neither the motive for the tattoo, the time contemplated before getting tattooed nor the time elapsed since the last tattoo. Even the expressed intention to get a(nother) tattoo predicts increased short-sightedness and helps establish the direction of causality between tattoos and short-sightedness.

Lifespans are becoming more equal, with octogenarians & nonagenarians accounting for most deaths; extrapolation of the trend indicates that most children born this millennium will reach 100.

Vaupel, James W., Francisco Villavicencio, and Marie-Pier B. Boucher. 2019. “Demographic Perspectives on the Rise of Longevity.” SocArXiv. August 25. doi:10.31235/osf.io/gdjtv

Abstract
Background: This article reviews findings about the rise of life expectancy, current levels of life expectancy in countries with high life expectancies, and possible future trends in life expectancy. Maximum lifespans and the equality of lifespans are also considered.
Methods: Demographic data on age-specific mortality are used to estimate life expectancy. Validated data on exceptional lifespans are used to study the maximum length of life. Findings of the most significant publications are critically summarized.
Results: In the countries doing best, life expectancy started to increase around 1840 at a pace of almost 2.5 years per decade. This trend has continued until the present. Contrary to classical evolutionary theories of senescence and contrary to the predictions of many experts, the frontier of survival is advancing to higher ages. Furthermore, lifespans are becoming more equal, with octogenarians and nonagenarians accounting for most deaths in countries with high life expectancy. Extrapolation of the trend indicates that most children born this millennium will celebrate their 100th birthdays. Considerable uncertainty, however, clouds forecasts of life expectancy and maximum lifespans: life expectancy and maximum lifespan might increase very little if at all or longevity might rise much faster than in the past.
Conclusions: Substantial progress has been made over the past three decades in deepening understanding of how long humans have lived and have long they might live. The social, economic, health, cultural and political consequences of further increases in longevity are so significant that the development of more powerful methods of forecasting is a priority.

People who were bitten by a snake (either venomous or not) scored lower in fear of snakes; people could become fear immunized even against highly biologically prepared fearful stimuli

Coelho, Carlos M., Panrapee Suttiwan, and Andras N. Zsido. 2019. “Fear Inoculation Among Snake Experts.” PsyArXiv. August 24. doi:10.31234/osf.io/ph5ug

Abstract: Prepared phobias are often seen as acquired rapidly, generalize broadly and are resistant to extinction. Nonetheless provided opportunity for innocuous contact with certain kinds of stimuli people tend to show less fear when compared with others who never or rarely deal with the same stimuli. This study finds that people who were bitten by a snake (either venomous or not) scored lower in fear of snakes, as measured by the SNAQ-12, and SPQ surveys. These fearless people also have more experience with snakes than those who were not bitten. Results suggest that people could become immunized even against highly biologically prepared fearful stimuli, such as snakes, after a certain amount of previous benign exposure. We stress that lack of fear might bring people to become unworried and develop extreme risk of snakebite envenomation, which has recently (2017) been classified by the World Health Organization as a category A neglected tropical disease.

Sexual narcissism was positively associated with sexual functioning in both women and men; in the women's sample, sexual narcissism was related to a positive genital self-image

Sexual narcissism and its association with sexual and well-being outcomes. Verena Klein et al. Personality and Individual Differences, Volume 152, 1 January 2020, 109557. https://doi.org/10.1016/j.paid.2019.109557

Abstract: Theories on narcissism are traditionally closely related to sexuality. Most research on the association between narcissism and sexual behavior, however, has focused on harmful/maladaptive outcomes. The aim of the present two studies was to examine the possible health-promoting influence of both global and sexual narcissism on sexual function and genital self-image. In Study 1, sexual narcissism was positively associated with sexual functioning in both women and men (N = 505, online-recruited German participants). In the women's sample, sexual narcissism was related to a positive genital self-image. The facet sexual skill was identified as the most important predictor for sexual function and positive genital self-image in both women and men. Study 2 replicated and extended this association in an online sample of US Americans (N = 588) by including quality of life measures. Underscoring the benign nature of the sexual skill facet, this subscale was associated with quality of life in both women and men. The idea of a possible beneficial influence of sexual narcissism on sexuality related outcomes is discussed.

Sexual experience has no effect on male mating or reproductive success in house mice

Sexual experience has no effect on male mating or reproductive success in house mice. Kerstin E. Thonhauser, Alexandra Raffetzeder & Dustin J. Penn. Scientific Reports, August 21 2019, volume 9, 12145 (2019). https://www.nature.com/articles/s41598-019-48392-x

Abstract: The ability to learn from experience can improve Darwinian fitness, but few studies have tested whether sexual experience enhances reproductive success. We conducted a study with wild-derived house mice (Mus musculus musculus) in which we manipulated male sexual experience and allowed females to choose between (1) a sexually experienced versus a virgin male, (2) two sexually experienced males, or (3) two virgin males (n = 60 females and 120 males). This design allowed us to test whether females are more likely to mate multiply when they encounter more virgin males, which are known to be infanticidal. We recorded females’ preference and mating behaviours, and conducted genetic paternity analyses to determine male reproductive success. We found no evidence that sexual experience influenced male mating or reproductive success, and no evidence that the number of virgin males influenced female multiple mating. Females always copulated with both males and 58% of the litters were multiple-sired. Females’ initial attraction to a male correlated with their social preferences, but neither of these preference behaviours predicted male reproductive success – raising caveats for using mating preferences as surrogates for mate choice. Male reproductive success was predicted by mating order, but unexpectedly, males that copulated first sired fewer offspring.

“Daddies,” “Cougars”, & Relationship and Sexual Well-Being among Older Adults & Young Lovers: Women partnered to older men had less sex and more issues related to sexual satisfaction

“Daddies,” “Cougars,” and Their Partners Past Midlife: Gender Attitudes and Relationship and Sexual Well-Being among Older Adults in Age-Heterogenous Partnerships. Tony Silva. Socius: Sociological Research for a Dynamic World, August 19, 2019. https://doi.org/10.1177/2378023119869452

Abstract: Discussion of “daddies” has exploded in popular discourse, yet there is little sociological research on age-heterogenous partnerships. This paper uses data from the 2013 Midlife in the United States survey and the 2015–2016 National Social Life, Health, and Aging Project to examine age-heterogenous partnerships at older ages (63 was the approximate average age of each sample). On most measures of life satisfaction and relationship well-being, individuals in age-heterogenous partnerships—regardless of age or gender—were not very different from their counterparts in age-homogenous relationships. Some differences did emerge, however, especially related to sexual well-being. Women partnered to older men had less sex and more issues related to sexual satisfaction than their counterparts in age-homogenous relationships. Latent class analyses suggest that these differences were driven by around 40 percent of younger women partnered to older men, a minority of whom were deeply dissatisfied. This research helps address the underrepresentation of sexuality research at older ages and the sociological research gap about age-heterogenous partnerships.

Absolute and relative estimates of genetic and environmental variance in brain structure volumes

Absolute and relative estimates of genetic and environmental variance in brain structure volumes. Lachlan T. Strike et al. Brain Structure and Function, August 19 2019. https://link.springer.com/article/10.1007/s00429-019-01931-8

Abstract: Comparing estimates of the amount of genetic and environmental variance for different brain structures may elucidate differences in the genetic architecture or developmental constraints of individual brain structures. However, most studies compare estimates of relative genetic (heritability) and environmental variance in brain structure, which do not reflect differences in absolute variance between brain regions. Here we used a population sample of young adult twins and singleton siblings of twins (n = 791; M = 23 years, Queensland Twin IMaging study) to estimate the absolute genetic and environmental variance, standardised by the phenotypic mean, in the size of cortical, subcortical, and ventricular brain structures. Mean-standardised genetic variance differed widely across structures [ 23.5-fold range 0.52% (hippocampus) to 12.28% (lateral ventricles) ], but the range of estimates within cortical, subcortical, or ventricular structures was more moderate (two to fivefold range). There was no association between mean-standardised and relative measures of genetic variance (i.e., heritability) in brain structure volumes. We found similar results in an independent sample (n = 1075, M = 29 years, Human Connectome Project). These findings open important new lines of enquiry: namely, understanding the bases of these variance patterns, and their implications regarding the genetic architecture, evolution, and development of the human brain.

Radical lifespan disparities exist in the animal kingdom: Revamping the Evolutionary Theories of Aging

Revamping the Evolutionary Theories of Aging. Adiv A. Johnsona, Maxim N. Shokhirev, Boris Shoshitaishvili. Ageing Research Reviews, August 23 2019, 100947. https://doi.org/10.1016/j.arr.2019.100947

Highlights
• Extrinsic mortality is one of the most important drivers in the evolution of aging.
• Classical predictions expect higher extrinsic mortality to shorten evolved lifespan.
• The bulk of published data conform to the classical evolutionary theories of aging.
• Increased extrinsic mortality can sometimes select for longer evolved lifespans.
• Immortal animals that experience extrinsic mortality challenge classical theories.
• The aging response to extrinsic mortality involves multiple interacting factors.

Abstract: Radical lifespan disparities exist in the animal kingdom. While the ocean quahog can survive for half a millennium, the mayfly survives for less than 48 hours. The evolutionary theories of aging seek to explain why such stark longevity differences exist and why a deleterious process like aging evolved. The classical mutation accumulation, antagonistic pleiotropy, and disposable soma theories predict that increased extrinsic mortality should select for the evolution of shorter lifespans and vice versa. Most experimental and comparative field studies conform to this prediction. Indeed, animals with extreme longevity (e.g., Greenland shark, bowhead whale, giant tortoise, vestimentiferan tubeworms) typically experience minimal predation. However, data from guppies, nematodes, and computational models show that increased extrinsic mortality can sometimes lead to longer evolved lifespans. The existence of theoretically immortal animals that experience extrinsic mortality – like planarian flatworms, panther worms, and hydra – further challenges classical assumptions. Octopuses pose another puzzle by exhibiting short lifespans and an uncanny intelligence, the latter of which is often associated with longevity and reduced extrinsic mortality. The evolutionary response to extrinsic mortality is likely dependent on multiple interacting factors in the organism, population, and ecology, including food availability, population density, reproductive cost, age-mortality interactions, and the mortality source.

However, since radical people represent only 20% of the population and there was no effect for Facebook or blogs, the overall effect of the Internet was moderation, not polarization

Tatsuo Tanaka, 2019. "Does the Internet cause polarization? -Panel survey in Japan-," Keio-IES Discussion Paper Series 2019-015, Institute for Economics Studies, Keio University. https://ideas.repec.org/p/keo/dpaper/2019-015.html

Abstract: There is concern that the Internet causes ideological polarization through selective exposure and the echo chamber effect. This paper examines the effect of social media on polarization by applying a difference-in-difference approach to panel data of 50 thousand respondents in Japan. Japan is good case for this research because other factors affecting polarization like huge wealth gap and massive immigration are not serious issue, thus it offers quasi natural experimental situation to test the effect of the Internet. The results show that people who started using social media during the research period (targets) were no more polarized than people who did not (controls). There was a tendency for younger and politically moderate people to be less polarized. The only case in which the Internet increased polarization was for already radical people who started using Twitter. However, since radical people represent only 20% of the population and there was no effect for Facebook or blogs, the overall effect of the Internet was moderation, not polarization.

Growing body of evidence suggests that inconsistent hand preference is indicative of an increased disposition to update one’s beliefs upon exposure to novel information; this seems wrong

M. L., Vilsmeier, J. K., Voracek, M., & Tran, U. S. (2019). No Evidence That Lateral Preferences Predict Individual Differences in the Tendency to Update Mental Representations: A Replication-Extension Study. Collabra: Psychology, 5(1), 38. DOI: http://doi.org/10.1525/collabra.227

Abstract: A growing body of evidence suggests that inconsistent hand preference is indicative of an increased disposition to update one’s beliefs upon exposure to novel information. This is attributed to a facilitated exchange of information between the two brain hemispheres among inconsistent handers, compared to consistent handers. Currently available studies provide only indirect evidence for such an effect, were mostly based on small sample sizes, and did not provide measures of effect size. Small sample size is a major factor contributing to low replicability of research findings and false-positive results. We thus attempted to replicate Experiment 1 of Westfall, Corser and Jasper (2014), which appears to be representative of research on degree of handedness and belief updating in terms of the employed methods. We utilized data from a sample more than 10 times the size (N = 1243) of the original study and contrasted the commonly applied median-split technique to classify inconsistent and consistent handers with an empirically grounded classification scheme. Following a replication-extension approach, besides handedness, footedness was also explored. Only one out of 12 chi-squared tests reached significance and supported the original hypothesis that inconsistent handers stay with, or switch more often from, the status quo than consistent handers, depending on the valence of novel information. A small-telescopes analysis suggested that the original study had too low analytic power to detect its reported effect reliably. These results cast doubt on the assumption that inconsistent and consistent-handers differ in the tendency to update mental representations. We discuss the use of the median-split technique in handedness research, available neuroscientific evidence on interhemispheric interaction and inconsistent handedness, and venues of future research.

Credibility and Incredulity in Milgram’s Obedience Experiments: A Reanalysis of an Unpublished Test By Milgram’s assistant, Taketo Murata

Credibility and Incredulity in Milgram’s Obedience Experiments: A Reanalysis of an Unpublished Test. Gina Perry et al. Social Psychology Quarterly, August 22, 2019. https://doi.org/10.1177/0190272519861952

Abstract: This article analyzes variations in subject perceptions of pain in Milgram’s obedience experiments and their behavioral consequences. Based on an unpublished study by Milgram’s assistant, Taketo Murata, we report the relationship between the subjects’ belief that the learner was actually receiving painful electric shocks and their choice of shock level. This archival material indicates that in 18 of 23 variations of the experiment, the mean levels of shock for those who fully believed that they were inflicting pain were lower than for subjects who did not fully believe they were inflicting pain. These data suggest that the perception of pain inflated subject defiance and that subject skepticism inflated their obedience. This analysis revises our perception of the classical interpretation of the experiment and its putative relevance to the explanation of state atrocities, such as the Holocaust. It also raises the issue of dramaturgical credibility in experiments based on deception. The findings are discussed in the context of methodological questions about the reliability of Milgram’s questionnaire data and their broader theoretical relevance.

Both men and women found heroic targets to be more desirable than targets low in heroism, although the main effect of sex was stronger for women than men

Bhogal, Manpal S., and James E. Bartlett. 2019. “Further Support for the Role of Heroism in Human Mate Choice.” PsyArXiv. May 19. doi:10.31234/osf.io/2npfm

Abstract: Previous research has explored the role of prosociality in mate choice, predominantly focusing on the role of altruism. Although there is ample evidence to suggest altruism has evolved via mate choice, little research has unpacked prosociality by exploring the role of heroism in mate choice. Limited studies have been conducted in this area, and no studies have explored men’s desirability towards heroic targets. The aim of this study was to replicate and extend the limited research on the role of heroism in mate choice. Participants (n=276, 101 men and 175 women) rated several scenarios varying in heroism, whereby they were asked to rate how desirable targets were for a short-term and long-term relationship. The findings show that both men and women found heroic targets to be more desirable than targets low in heroism, although the main effect of sex was stronger for women than men. Furthermore, high heroic targets were rated as more desirable for long-term compared to short-term relationships, thus replicating and extending previous research. The findings add support to the adaptive role of heroism in human mate choice by exploring the role of heroism in both male and female mate choice. Data, materials, and the preregistered hypotheses/protocol are available on the Open Science Framework (osf.io/qbzw7/?view_only=e66411df988844cfa39e63c51ed33131)

However, keeping pets, especially cats, and even more being injured by pets, were strongly negatively associated with many facets of quality of life

Friends with malefit. The effects of keeping dogs and cats, sustaining animal-related injuries and Toxoplasma infection on health and quality of life. Jaroslav Flegr, Marek Preiss. bioRxiv, August 21, 2019. https://doi.org/10.1101/742734

Abstract: Many studies show that keeping cats and dogs has a positive impact on humans’ physical and mental health and quality of life. The existence of this “pet phenomenon” is now widely discussed because other studies performed recently have demonstrated a negative impact of owning pets or no impact at all. The main problem of many studies was the autoselection – participants were informed about the aims of the study during recruitment and later likely described their health and wellbeing according to their personal beliefs and wishes, not according to their real status. To avoid this source of bias, we did not mention pets during participant recruitment and hid the pet-related questions among many hundreds of questions in an 80-minute Internet questionnaire. Results of our study performed on a sample of on 10,858 subjects showed that liking cats and dogs has a weak positive association with quality of life. However, keeping pets, especially cats, and even more being injured by pets, were strongly negatively associated with many facets of quality of life. Our data also confirmed that infection by the cat parasite Toxoplasma had a very strong negative effect on quality of life, especially on mental health. However, the infection was not responsible for the observed negative effects of keeping pets, as these effects were much stronger in 1,527 Toxoplasma-free subjects than in the whole population. Any cross-sectional study cannot discriminate between a cause and an effect. However, because of the large and still growing popularity of keeping pets, the existence and nature of the reverse pet phenomenon deserve the outmost attention.
