Jolly, Eshin, and Luke J. Chang. 2018. “Gossip Drives Vicarious Learning and Facilitates Robust Social Connections.” PsyArXiv. August 11. doi:10.31234/osf.io/qau5s
Abstract: Exchanging gossip is a ubiquitous and complex human behavior, yet its precise social function remains poorly understood. Prior work has focused on characterizing its role in increasing cooperation through social sanctioning. However, gossip has been theorized to have a more fundamental role in social life. Here we provide empirical evidence that gossip plays a critical role in vicarious learning and social bonding. First, we establish the conditions under which individuals spontaneously engage in gossip, and demonstrate that gossip promotes the rapid spread of information about others’ unobserved actions, which causally influences future behavior. Second, we demonstrate that gossip facilitates the formation of social connections between individuals. Conversants feel more positively towards each other relative to other individuals, influence each other’s future behavior, and align social impressions. These results directly contradict the commonly held view that gossip is primarily defamatory in nature, and instead demonstrate that gossip can provide a rich source of information to aid in navigating the social world that ultimately leads to more cooperative interactions by providing a mechanism to quickly forge social connections.

We designed a mobile video game to test spatial ability & tested more than 2.5 million people from every country; spatial ability of the population is correlated with country economic wealth, & gender inequality of a country is predictive of gender differences in navigation ability
Global Determinants of Navigation Ability. Antoine Coutrot et al. Current Biology, https://doi.org/10.1016/j.cub.2018.06.009
Highlights
• We designed a mobile video game to test spatial ability in humans
• We tested more than 2.5 million people from every country in the world
• Spatial ability of the population of a country is correlated with economic wealth
• Gender inequality of a country is predictive of gender differences in navigation ability
Summary: Human spatial ability is modulated by a number of factors, including age [1, 2, 3] and gender [4, 5]. Although a few studies showed that culture influences cognitive strategies [6, 7, 8, 9, 10, 11, 12, 13], the interaction between these factors has never been globally assessed as this requires testing millions of people of all ages across many different countries in the world. Since countries vary in their geographical and cultural properties, we predicted that these variations give rise to an organized spatial distribution of cognition at a planetary-wide scale. To test this hypothesis, we developed a mobile-app-based cognitive task, measuring non-verbal spatial navigation ability in more than 2.5 million people and sampling populations in every nation state. We focused on spatial navigation due to its universal requirement across cultures. Using a clustering approach, we find that navigation ability is clustered into five distinct, yet geographically related, groups of countries. Specifically, the economic wealth of a nation was predictive of the average navigation ability of its inhabitants, and gender inequality was predictive of the size of performance difference between males and females. Thus, cognitive abilities, at least for spatial navigation, are clustered according to economic wealth and gender inequalities globally, which has significant implications for cross-cultural studies and multi-center clinical trials using cognitive testing.

People are averse to machines making morally-relevant driving, legal, medical, and military decisions, and that this aversion is mediated by the perception that machines can neither fully think nor feel
People are averse to machines making moral decisions. Yochanan E. Bigman, Kurt Gray. Cognition, Volume 181, December 2018, Pages 21-34. https://doi.org/10.1016/j.cognition.2018.08.003
Abstract: Do people want autonomous machines making moral decisions? Nine studies suggest that that the answer is ‘no’—in part because machines lack a complete mind. Studies 1–6 find that people are averse to machines making morally-relevant driving, legal, medical, and military decisions, and that this aversion is mediated by the perception that machines can neither fully think nor feel. Studies 5–6 find that this aversion exists even when moral decisions have positive outcomes. Studies 7–9 briefly investigate three potential routes to increasing the acceptability of machine moral decision-making: limiting the machine to an advisory role (Study 7), increasing machines’ perceived experience (Study 8), and increasing machines’ perceived expertise (Study 9). Although some of these routes show promise, the aversion to machine moral decision-making is difficult to eliminate. This aversion may prove challenging for the integration of autonomous technology in moral domains including medicine, the law, the military, and self-driving vehicles.

Women preferred stoic men who worked even though they were experiencing health problems as long-term mates, disregarding the male's facial symmetry and physique; in short-term mate choice, disregarded stoicism
Female Choice and Male Stoicism. Susan G. Brown, Susan Shirachi, and Danielle Zandbergen. Journal of Evolutionary Medicine, https://www.ashdin.com/abstract/female-choice-and-male-stoicism-3240.html
Abstract: Men consistently report that they are healthier than women but have higher mortality rates. We hypothesized that men were sexually selected to present themselves as healthy to possible mates, according to predictions from health selection theory. The present study tested this theory by contrasting known influences of female mate choice with male's reactions to a health problem (flu symptoms, reaction to vog (air pollution associated with volcanic emissions in the Hawaiian islands) or a headache). Participants viewed three sets of slides contrasting male facial symmetry, physique, and status with stoicism (defined as ignoring a health problem) and were asked to choose which male they preferred as a long-term or a short-term mate. Participants preferred stoic men who worked even though they were experiencing health problems as long-term mates, disregarding the male's facial symmetry and physique. Status also significantly affected long-term mate choice. In short-term mate choice, participants shifted their preferences to symmetrical faces and mesomorphic bodies, signals of attractiveness, disregarding stoicism. In conclusion, our data provide support for health selection theory. Additionally, preventive health measures directed at men should recognize their reluctance to recognize minor health problems and focus on techniques that enhance men's perception of their health symptoms.

Masturbation with a Tool by an Infant Male Chimpanzee
Masturbation with a Tool by an Infant Male Chimpanzee. Michio Nakamura. Graduate School of Science, Kyoto University, Japan. http://mahale.main.jp/PAN/2018/001.html
INTRODUCTION
Here I report a case of “masturbation” with a tool by a wild infant chimpanzee. More accurately, the infant male inserted his erect penis into a wadge discarded by an adult male and performed several thrusts, as if he was copulating with the wadge. The observed “masturbation” did not involve ejaculation, because infant chimpanzees are unable to ejaculate. A similar behavior, i.e., rubbing the penis against a piece of fruit (e.g., orange peel), was reported for infant male orangutans in captivity (Harrison 1962). There are also some reported cases of captive or rehabilitant orangutans and chimpanzees stimulating their own genitals with tools (Dixson 2012).
Masturbation, or self-stimulation of one’s own sexual organs, is common among humans and nowadays is regarded as useful for healthy sexual development (Kaestle & Allen 2011). Various nonhuman primates are also known to masturbate (Thomsen et al. 2003; Dixson 2012; Thomsen & Sommer 2015); therefore, it may be a phylogenetically ancient behavior. However, there are relatively few studies that focus on masturbation among nonhuman primates in the wild (Thomsen & Soltis 2004). Male chimpanzees (Pan troglodytes) are known to stimulate their own penises. Although Goodall (1989) noted that captive chimpanzees sometimes ejaculate by stimulating their own penises, it had not been observed to result in ejaculation in the wild conspecifics at Gombe. Similarly, at Mahale, it is common for males to “fumble with penis,” but without it culminating in ejaculation (Nishida et al. 1999). Such fumbling of penis is done usually by hand (and sometimes by foot), but, thus far, I have found no reports of such penile-stimulating behaviors with tools, at least in wild chimpanzee populations.

Sex and age preferences: Why is age so important in human mating?
Conroy-Beam, D., & Buss, D. M. (2018). Why is age so important in human mating? Evolved age preferences and their influences on multiple mating behaviors. Evolutionary Behavioral Sciences. Advance online publication. http://dx.doi.org/10.1037/ebs0000127
Abstract: Evolutionary theorizing suggests that chronological age, because it is so strongly linked with key reproductive qualities like fertility, should be an exceptionally consequential variable in mate selection. We review voluminous evidence for mate preferences for age and the substantial and varied behavioral sequelae of those preferences. These include (a) in actual marriage decisions, men choose younger wives, and women choose older husbands, on average in all of the dozens of cultures studied; (b) in personal advertisements, men and women seek partners consistent with their expressed age preferences; (c) chronological age determines number of “hits” received in online dating services; (d) the age of potential bride influences the amount of money spent on premarriage customs; (e) men’s mate retention effort, including commitment manipulation, resource provisioning, and intrasexual threats, is significantly predicted by the wife’s age; and (f) chronological age is an important sex-linked cause of divorce. The far-reaching ramifications of age also extend to (g) tactics of intrasexual competition, (h) predictors of mate value discrepancies, (i) victims of sex crimes, and (j) prostitution patterns. Finally, chronological age predicts (k) probability of remarriage, and (l) the age gap between grooms and brides upon remarriage. We synthesize evidence from diverse methods, across different cultures, and over time spans of centuries. Massive converging evidence provides a powerful, yet complex, understanding of the evolutionary importance of age in multiple mating outcomes over the human life span.

Pakistan's pivot to coal: Plan to spend $35bn loan from China on new power stations looks set to continue under Khan
Pakistan’s pivot to coal to boost energy gets critics fired up. Kiran Stacey in Lahore July 31, 2018. Financial Times.
https://www.ft.com/content/5cd07544-7960-11e8-af48-190d103e32a4
Plan to spend $35bn loan from China on new power stations looks set to continue under Khan
Pakistan believes it may have found a way out of its long-term energy supply crisis, thanks largely to more than $35bn worth of loans provided by China under the $60bn China-Pakistan Economic Corridor (CPEC).
The country has experienced years of rolling blackouts that have left residents in the dark and stifled the country’s manufacturing industries.
But now it is investing in an energy technology that is fast going out of fashion in other parts of the region — coal.
Under the CPEC, Beijing is planning to spend at least $35bn building new power stations, which will be mainly coal-fired, using resources from coalfields at Thar, about 400km east of Karachi. The plans will mean building 9.5 gigawatts of new coal-fired capacity — a third of the total capacity the country has already built.
This is in stark contrast with India, which recently said it would not approve any more new coal power plants — not least because the unit price of solar power has dropped below that of coal.
The previous government has defended its energy policies. Shehbaz Sharif, head of the Pakistan Muslim League-Nawaz party, which lost power in last week’s election, told the Financial Times before the vote: “We have built 11,000 megawatts of additional capacity in the space of five years, compared with 18,000 over the previous 66 years.”
And the strategy looks set to continue under the new prime minister Imran Khan, head of the Pakistan Tehreek-e-Insaf party. Again speaking before the election, Mr Khan told the FT he backed using Thar coal to boost the country’s electricity supplies. “Thar coal is in a desert, it’s near the coast, and there are new technologies which now make it possible that you don’t damage the environment,” he said.
Defenders of Pakistan’s build-up of coal point out that the fuel currently accounts for a very small fraction of the country’s installed electricity capacity. In India, that figure is around 75 per cent.
They also say that with tariffs higher in Pakistan than in neighbouring countries, encouraging cheap electricity supply is essential to help develop exporting manufacturers. The average electricity tariff for industry is around $0.13 per kilowatt-hour, compared with $0.12 in India and $0.09 in Bangladesh.
Pakistan exported goods worth 8.2 per cent of its gross domestic product last year, according to the World Bank, compared with 15 per cent by Bangladesh and nearly 19 per cent by India.
“Manufacturers in India and Bangladesh get cheaper electricity than those in Pakistan do,” says Ehsan Malik, chief executive of the Pakistan Business Council. “This is particularly problematic for the garment industry, especially since all three countries make clothes at the lower end of the sector, where energy prices account for a higher proportion of costs.”
Others, however, warn that while solar prices are falling, Pakistan is building a series of large power stations that will not only pollute the environment but could also saddle the country with high debts and could even become stranded assets in the long run.
Fiza Farhan, an independent development consultant and a former director of Buksh Energy, a solar power company, says: “I have banged my head against walls for years trying to get the government to launch solar projects on mega scales.
“But it was impossible to get projects into the final stage — every time we would get to the financing stage, the government would revise the tariffs.”
Economists warn, meanwhile, that the stress in the electricity sector is likely to become worse in the near term.
With the country’s stocks of foreign currency reserves rapidly declining, experts expect the new government to approach the International Monetary Fund for a bailout within months. The terms of that bailout, they warn, could include renegotiating or cancelling some of the projects backed by China and raising electricity tariffs.
Mohammed Sohail, chief executive of Topline Securities, a Karachi-based investment advisory company, says: “This government will also have to reduce expenditure in a major way through unpopular measures.”

Association between physical exercise and mental health in 1·2 million individuals in the USA between 2011 and 2015: More exercise was not always better
Association between physical exercise and mental health in 1·2 million individuals in the USA between 2011 and 2015: a cross-sectional study. Sammi R Chekroud et al. The Lancet Psychiatry, August 08, 2018. DOI:https://doi.org/10.1016/S2215-0366(18)30227-X
Summary
Background: Exercise is known to be associated with reduced risk of all-cause mortality, cardiovascular disease, stroke, and diabetes, but its association with mental health remains unclear. We aimed to examine the association between exercise and mental health burden in a large sample, and to better understand the influence of exercise type, frequency, duration, and intensity.
Methods: In this cross-sectional study, we analysed data from 1 237 194 people aged 18 years or older in the USA from the 2011, 2013, and 2015 Centers for Disease Control and Prevention Behavioral Risk Factors Surveillance System survey. We compared the number of days of bad self-reported mental health between individuals who exercised and those who did not, using an exact non-parametric matching procedure to balance the two groups in terms of age, race, gender, marital status, income, education level, body-mass index category, self-reported physical health, and previous diagnosis of depression. We examined the effects of exercise type, duration, frequency, and intensity using regression methods adjusted for potential confounders, and did multiple sensitivity analyses.
Findings: in the comments section
Interpretation: In a large US sample, physical exercise was significantly and meaningfully associated with self-reported mental health burden in the past month. More exercise was not always better. Differences as a function of exercise were large relative to other demographic variables such as education and income. Specific types, durations, and frequencies of exercise might be more effective clinical targets than others for reducing mental health burden, and merit interventional study.

By 2050, stringent climate mitigation policy, if implemented evenly across all sectors & regions, would have a greater negative impact on global hunger & food consumption than the direct impacts of climate change due to indirect impacts on prices/supplies of agri commodities
Risk of increased food insecurity under stringent global climate change mitigation policy. Tomoko Hasegawa, Shinichiro Fujimori, Petr Havlík, Hugo Valin, Benjamin Leon Bodirsky, Jonathan C.

Nature Climate Change, volume 8, pages699–703 (2018), https://www.nature.com/articles/s41558-018-0230-x
Abstract: Food insecurity can be directly exacerbated by climate change due to crop-production-related impacts of warmer and drier conditions that are expected in important agricultural regions1,2,3. However, efforts to mitigate climate change through comprehensive, economy-wide GHG emissions reductions may also negatively affect food security, due to indirect impacts on prices and supplies of key agricultural commodities4,5,6. Here we conduct a multiple model assessment on the combined effects of climate change and climate mitigation efforts on agricultural commodity prices, dietary energy availability and the population at risk of hunger. A robust finding is that by 2050, stringent climate mitigation policy, if implemented evenly across all sectors and regions, would have a greater negative impact on global hunger and food consumption than the direct impacts of climate change. The negative impacts would be most prevalent in vulnerable, low-income regions such as sub-Saharan Africa and South Asia, where food security problems are already acute.

Testosterone & self-perceived mate value increased following a manipulated “victory” in a sporting competition & were associated with heightened sociosexuality, & increased expectations toward approaching attractive women
Tandem Androgenic and Psychological Shifts in Male Reproductive Effort Following a Manipulated “Win” or “Loss” in a Sporting Competition. Daniel P. Longman et al. Human Nature, https://link.springer.com/article/10.1007/s12110-018-9323-5
Abstract: Male-male competition is involved in inter- and intrasexual selection, with both endocrine and psychological factors presumably contributing to reproductive success in human males. We examined relationships among men’s naturally occurring testosterone, their self-perceived mate value (SPMV), self-esteem, sociosexuality, and expected likelihood of approaching attractive women versus situations leading to child involvement. We then monitored changes in these measures in male rowers (N = 38) from Cambridge, UK, following a manipulated “win” or “loss” as a result of an indoor rowing contest. Baseline results revealed that men with heightened testosterone and SPMV values typically had greater inclinations toward engaging in casual sexual relationships and a higher likelihood of approaching attractive women in a hypothetical social situation. As anticipated, both testosterone and SPMV increased following a manipulated “victory” and were associated with heightened sociosexuality, and increased expectations toward approaching attractive women versus individuals who would involve them in interacting with children after the race. SPMV and self-esteem appeared to mediate some of the effects of testosterone on post-race values. These findings are considered in the broader context of individual trade-offs between mating and parental effort and a model of the concurrent and dynamic androgenic and psychological influences contributing to male reproductive effort and success.

Baseline results revealed that men with heightened testosterone and SPMV values typically had greater inclinations toward engaging in casual sexual relationships and a higher likelihood of approaching attractive women in a hypothetical social situation. As anticipated, both testosterone and SPMV increased following a manipulated “victory” and were associated with heightened sociosexuality, and increased expectations toward approaching attractive women versus individuals who would involve them in interacting with children after the race. SPMV and self-esteem appeared to mediate some of the effects of testosterone on post-race values. These findings are considered in the broader context of individual trade-offs between mating and parental effort and a model of the concurrent and dynamic androgenic and psychological influences contributing to male reproductive effort and success.
Strong negative effects are attributed to sex dolls both in public & academic debates; sparse research points to strong positive outcomes as well: sex dolls can provide a lot of sexual & emotional satisfaction, create feelings of comfort, peace & even love
Sex toys, sex dolls, sex robots: Our under-researched bed-fellows. N. Döring, S. Pöschl. Sexologies, Volume 27, Issue 3, July–September 2018, Pages e51-e55. https://doi.org/10.1016/j.sexol.2018.05.009
Summary: In the 21st century, sexual products such as sex toys, sex dolls and sex robots are openly marketed on the Internet. The online retailer Amazon alone provides literally thousands of sexual wellness products. The Internet has done with sexual products what it has already achieved with pornography: it has expanded and diversified the market, made sexual products more accessible and affordable, and thus normalized their use. Research, though, is lagging behind: in comparison to the large body of pornography studies, research on sexual products, their users, uses and outcomes is scarce. The present paper therefore reviews both the state of technological development and the state of research regarding sex toys, sex dolls and sex robots marketed on the Internet. For each of these three groups of sexual product, we first present the range of products available and then provide data on their users and use. Finally, outcomes of sexual product use are discussed based on theoretical assumptions, available data and selected user experiences. Operating within a Positive Sexuality Framework (Williams et al., 2015) and a Positive Technology Framework (Riva et al., 2012), both rooted in the Positive Psychology Approach (Seligman and Csikszentmihalyi, 2000), the paper argues that sexual products have the potential to improve sexual well-being in various populations. Health professionals working in the field of sexuality need to be well-informed about the ever-evolving market of more and more technologically advanced sexual products. It is their call to foster both, the health-related use of existing sexual products and health-related development of future sexual products.

Strong negative effects are attributed to sex dolls both in public and academic debates: men who buy and use female or even child-like sex dolls could be led to objectify and abuse real women and children just as they do their dolls (Ray, 2016; Valverde, 2012). Men who accept their dolls as social companions could harm themselves by no longer seek-ing for a human partner. Even innocuous sex doll use could lead to problems for the owner due to stigmatization by family and friends, leading to embarrassment, social withdrawal and guilt (Knox et al., 2017; Ray, 2016). However, the sparse research points to strong positive outcomes as well: sex dolls can provide a lot of sexual and emotional satisfaction, create feelings of comfort, peace and even love, as doll-owners report in surveys and interviews (Ferguson, 2010; Valverde, 2012).
In doll-owner forums, there are a lot of nuanced discussions about the pros and cons of sex dolls. While some owners confirm the problem of social stigmatization, others tell success stories about coming out as a doll-owner to their friends and family and finding acceptance. While some feel anxious about falling in love or becoming over-attached to a doll at the cost of real human contact, others describe the doll as a therapeutic tool that helps them to overcome a traumatic breakup or to cope with seemingly inevitable social and sexual deprivation due to physical and/or mental impairment.

Linguistic Inquiry and Word Count Markers of Narcissism
Holtzman, Nicholas S., Allison M. Tackman, Albrecht Kuefner, Fenne große Deters, Mitja Back, Brent Donnellan, James W. Pennebaker, et al. 2018. “LIWC Markers of Narcissism: An Exploratory LIWC Analysis of 15 Samples.” PsyArXiv. August 8. doi:10.31234/osf.io/yvna6
Abstract: Narcissism is virtually unrelated to using first-person singular pronouns (Carey et al., [2015] Journal of Personality and Social Psychology, 109). The degree to which narcissism is linked to other aspects of language use, however, remains unclear. We conducted a multi-site, multi-measure, and dual-language project to identify potential linguistic markers of narcissism. We applied the Linguistic Inquiry and Word Count (LIWC) program to a large number of written and spoken texts across 15 samples (total N = 4,941). The strongest positive correlates of narcissism were: using words related to sports, second-person pronouns, and swear words. The strongest negative correlates of narcissism were: using anxiety/fear words, tentative words, and words related to sensory/perceptual processes. All effects were small (each |r| less than .10).

Participants lie significantly more in the random-draw task than in the real-effort task, leading to the conclusion lying about luck is intrinsically less costly than lying about performance
Lying about luck versus lying about performance. Agne Kajackaite. Journal of Economic Behavior & Organization, Volume 153, September 2018, Pages 194-199. https://doi.org/10.1016/j.jebo.2018.07.010
Highlights
• I compare lying behavior in a real-effort task and a random-draw task.
• Participants lie more in the random-draw task than in the real-effort task.
• Lying about luck is intrinsically less costly than lying about performance.
• More generally, the way outcomes are determined affects the decision to lie.
Abstract: I compare lying behavior in a real-effort task in which participants have control over outcomes and a task in which outcomes are determined by pure luck. Participants lie significantly more in the random-draw task than in the real-effort task, leading to the conclusion lying about luck is intrinsically less costly than lying about performance.

We study whether face-to-face group deliberation changes other-regarding preferences; social interactions do indeed change individuals’ preferences; specifically, individuals whose preferences are extremely egoistic and also unchanging tend to influence others the most
Social interactions and the influence of “extremists”. Crawford Donna Harris. Journal of Economic Behavior & Organization, Volume 153, September 2018, Pages 238-266.

Highlights
• We study whether face-to-face group deliberation changes other-regarding preferences, particularly when individuals have to make their decisions alone afterwards.
• We use a structural choice-revealed preference approach to measure each individual’s other-regarding preferences in a modified dictator game.
• We examine heterogeneity in preferences and changes in these preferences before and after group deliberation.
• We find that social interactions do indeed change individual preferences, even after they have left the group. In particularly, preferences of individuals in the same group become more homogenous after interactions.
• We also find that students are more susceptible to social influence of individuals with extremely selfish preference (the “extremists” in our title) compared to non-students.
Abstract: A large literature has shown evidence that people are influenced by others, especially in group interactions. However, little is known about whether such influence remains after they have left the group. Using a modified dictator game and a structural choice-revealed preference approach, we measure an individual’s preferences before and after face-to-face interactions in a small group and then examine whether a change in preferences is observed after subjects have left the group and have to make their decisions alone. We find that social interactions do indeed change individuals’ preferences. Specifically, individuals whose preferences are extremely egoistic and also unchanging tend to influence others the most. These “left extremists” are more likely to be male and these effects are more prevalent amongst student subjects than non-student.

Intersectional Escape: Older Women Elude Agentic Prescriptions More Than Older Men
Intersectional Escape: Older Women Elude Agentic Prescriptions More Than Older Men. Ashley E. Martin, Michael S. North, Katherine W. Phillips. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167218784895
Abstract: Both older individuals and women are proscribed from engaging in power-related behaviors, with women proscribed from behaving agentically and older individuals expected to cede desirable resources through “Succession.” However, little is known about whether these overlapping agency prescriptions equally target men and women across the lifespan. In seven studies, we find that older men face the strongest prescriptions to behave less agentically and cede resources, whereas older women are comparatively spared. We show that agency prescriptions more strongly target older men, compared to older women (Studies 1a, 1b, 2) and their younger counterparts (Studies 3 and 4) and examine social and economic consequences for agentic behavior in political, economic, and academic domains. We also find that older men garner more extreme (i.e., polarized) reactions due to their greater perceived resource threat (Studies 4-6). We conclude by discussing theoretical implications for diversity research and practical considerations for accommodating the fast-aging population.
