Abstract: Humans can experience a wide variety of different thoughts and feelings in the course of everyday life. To successfully navigate the social world, people need to perceive, understand, and predict others’ mental states. Previous research suggests that people use three dimensions to represent mental states: rationality, social impact, and valence. This 3d Mind Model allows people to efficiently “see” the state of another person’s mind by considering whether that state is rational or emotional, more or less socially impactful, and positive or negative. In the current investigation, we validate this model using neural, behavioral, and linguistic evidence. First, we examine the robustness of the 3d Mind Model by conducting a mega-analysis of four fMRI studies in which participants considered others’ mental states. We find evidence that rationality, social impact, and valence each contribute to explaining the neural representation of mental states. Second, we test whether the 3d Mind Model offers the optimal combination of dimensions for describing neural representations of mental state. Results reveal that the 3d Mind Model achieve the best performance among a large set of candidate dimensions. Indeed, it offers a highly explanatory account of mental state representation, explaining over 80% of reliable neural variance. Finally, we demonstrate that all three dimensions of the model likewise capture convergent behavioral and linguistic measures of mental state representation. Together, these findings provide strong support for the 3d Mind Model, indicating that is it is a robust and generalizable account of how people think about mental states.

Social media dreams were quite rare (2pct of all remembered dreams); their frequency correlated with neuroticism and extraversion
Social Media, Dreaming, and Personality: An Online Study. Michael Schredl and Anja S. Göritz. Cyberpsychology, Behavior, and Social Networking, Oct 3 2019. https://doi.org/10.1089/cyber.2019.0385
Abstract: Social media consumption plays an important role in everyday life and, thus, one would expect that this topic is reflected in dreams. This online survey included 1,349 participants (763 women, 586 men) completing questions about social media use in waking, percentage of social media dreams, and the Big Five personality dimensions. Social media dreams were quite rare (two percent of all remembered dreams), but their frequency correlated with neuroticism and extraversion—in addition to the amount of time using social media in waking—supporting the hypothesis that social media have a stronger effect on those person's inner life due to the higher importance attached to this channel of communication. For future research it would be of interest to elicit emotions related to social media in waking and the emotional tones of social media dreams to study whether positive and/or negative aspects of waking-life social media use are directly reflected in dreams.

Job referrals: Women tend to favor women when choosing a candidate, & men do not attach much importance to the gender; gendered networks alone fail to explain the observed gender homophily in referred-referrer pairs
Gender Bias in Job Referrals: An Experimental Test. Julie Beugnot, Emmanuel Peterlé. Journal of Economic Psychology, October 4 2019, 102209. https://doi.org/10.1016/j.joep.2019.102209
Highlights
• Gender homophily in job referral choices is largely observed in the field.
• We test whether an implicit same-gender bias exists in job referrals.
• We run a lab experiment to control social network and work environments.
• Only women tend to favor same-gender candidates when making referrals.
• We identify an implicit same-gender bias in the cooperative environment only.
Abstract: Employee referral programs, while efficient for the employer, have been shown to amplify sex-based occupational segregation in labor markets because of the tendency of workers to refer people of the same gender. We implement a controlled laboratory experiment that precludes any concern for network composition or reputation effects in referral choice. In this way, our experimental design allows us to disentangle statistical discrimination, preferences, and implicit same-gender bias. Our data suggest that women tend to favor women when choosing a candidate, whereas men do not attach much importance to the gender of potential candidates. We deduce from our various treatments that same-gender referrals are mainly driven by preferences in competitive environments and implicit same-gender bias in cooperative environments. Our findings add to the existing literature by highlighting that gendered networks alone fail to explain the observed gender homophily in referred-referrer pairs.

Impression formation on online dating sites: Effects of language errors in profile texts on perceptions of profile owners’ attractiveness
Impression formation on online dating sites: Effects of language errors in profile texts on perceptions of profile owners’ attractiveness. Tess Van der Zanden et al. Journal of Social and Personal Relationships, October 3, 2019. https://doi.org/10.1177/0265407519878787
Abstract: This article presents two experimental studies investigating the impact of language errors in online dating profiles on impression formation. A first study examined whether language errors have a negative effect on perceptions of attraction and dating intention and whether this effect is moderated by the presence of visual information, that is, the profile picture. This 2 (Language Errors/No Language Errors) × 2 (Visible/Blurred Picture) experiment revealed that language errors negatively affect perceptions of social and romantic attraction and that a visible picture on a profile positively affects perceptions of physical attraction. Study 2 focused on mechanical, rule-based, and informal language errors, which can each be attributed to different personality traits. Mechanical and rule-based errors lead to lower scores on, respectively, perceived attentiveness and intelligence, which in turn lead to lower attraction and dating intention scores. These results highlight the importance of error-free language use as a cue for attractiveness.

Dummy pills and pain relief; the connection between hostility and heart attacks in women with diabetes; and insomnia is not simply an adverse effect of depression
Matters of the Mind: Honest Placebos, Hostility and Heart Attacks, and Sleepless Nights. Rita Rubin. JAMA, October 3, 2019. doi:10.1001/jama.2019.15983
Dummy pills and pain relief, the connection between hostility and heart attacks in women with diabetes, and the notion that insomnia is not simply an adverse effect of depression have been the focus of recent studies.
“Honest” Placebos Might Help Relieve Back Pain
Until recently, the conventional wisdom was that placebo treatments worked only if patients who received them didn’t know they were placebos.
But not telling patients that sugar pills or saline injections are placebos raises ethical and legal questions related to informed consent.
Researchers have started to investigate the effectiveness of prescribing placebos with patients’ full knowledge, an approach called open-label placebo (OLP).
It turns out that the placebo effect can survive disclosure to patients, at least in those with chronic back pain, according to a German study recently published in Pain.
The researchers randomly assigned 127 people aged 19 years or older who had chronic back pain (persisting for at least 12 weeks) to usual care or usual care plus placebo. As part of the informed consent procedure before randomization, participants were shown a video produced by CBS New York that had been translated into German. The video contained information about the placebo effect in general and recent research findings about the potential benefits of OLPs.
Participants randomized to the placebo received capsules made by Zeebo Effect, a Vermont company that markets them as “honest placebos.” They’re not actually sugar pills—they contain microcrystalline cellulose, refined wood pulp commonly used as a food additive. Patients in the placebo group were told the capsules were placebos that they should take twice a day for 21 days.
The combination of OLP with treatment as usual significantly reduced patient-reported pain, disability, and depressive symptoms but not stress or anxiety, the study found. In addition, OLP treatment showed a trend toward reduced demand for analgesic rescue medication to help relieve back pain. However, OLP had no effect on objective measures of spine mobility, such as range of motion. This suggests that the approach wouldn’t work for conditions with primarily objective treatment outcomes, such as cardiovascular or immunological diseases, according to the authors.
Hostility and the Heart in Women With Diabetes
A growing body of evidence suggests that hostility is bad for the heart.
Recent findings reported in Menopause suggest this holds true for postmenopausal women with type 2 diabetes. Researchers tracked 15 029 women aged 50 to 79 years at enrollment, all of whom were participants in the Women’s Health Initiative (WHI), for 10 years on average. All of the women reported being treated for diabetes, either at the beginning of the study or during the follow-up period. None had been diagnosed with cardiovascular disease before entering the study.
At baseline, the researchers administered questionnaires to the women to assess a variety of personality traits.
During follow-up, 1118 cases of nonfatal or fatal myocardial infarction and 710 cases of stroke occurred. After accounting for confounders such as age, race and ethnicity, education, high cholesterol, and family history of myocardial infarction, women in the highest quartile of hostility had a 22% higher risk of a heart attack than women in the lowest quartile. No other personality traits were associated with coronary heart disease (CHD) risk, and there was no statistically significant association between hostility—or any other personality trait—and stroke risk.
In a stratified analysis, though, a higher level of hostility and CHD risk were significantly associated only in women diagnosed with diabetes during the course of the study, not those with the disease at baseline. The researchers speculated that among women with higher hostility, those who weren’t yet diagnosed with diabetes at the beginning of the study might have lived longer with impaired glucose homeostasis, in part because they might be less likely to engage in healthy behaviors such as seeing a physician regularly.
Previous research has found that higher levels of hostility in people with type 2 diabetes raised susceptibility to stress-induced inflammation, a possible explanation for the increased risk of a heart attack. However, another study also based on WHI participants, but not specifically those with diabetes, found that greater hostility was not associated with a higher risk of CHD, while greater optimism was linked to a lower risk.
Personality traits are not easily changed, the authors point out. But, at least, identifying patients with diabetes who have high hostility could lead to the testing of interventions that would help minimize their risk for adverse outcomes.
Sorting Out the Relationship Between Depression and Insomnia
Nearly 90% of people with major depressive disorder (MDD) report disturbed sleep, but a recent study in the Journal of Affective Disorders suggests that MDD and insomnia are comorbid yet separate disorders.
The study involved patients enrolled in the STAR*D (Sequenced Treatment Alternatives to Relieve Depression) study, a prospective, randomized clinical trial funded by the National Institutes of Health (NIH) that assessed the efficacy of several antidepressants and cognitive therapy for people with treatment-resistant depression.
The 7-year study enrolled 4041 outpatients aged 18 to 75 years with MDD and tested 4 different medications or medication combinations. The insomnia study assessed the first level of STAR*D, which tested citalopram for 12 or 14 weeks, depending on whether patients responded early or late.
The insomnia study excluded participants who had no postbaseline assessments as well as those who reported sleeping more than average, not less, bringing the total included in the analysis to 2788 people.
At baseline and 5 or 6 times during treatment with citalopram, researchers administered the Quick Inventory of Depressive Symptomology–Clinician Rated (QIDS-C) to assess symptom severity for the previous week. Three of the 16 items on the QIDS-C deal with insomnia, and the researchers combined them to arrive at a global insomnia score. Each QIDS-C item has a maximum score of 3, so the maximum global insomnia score, signifying the most severe insomnia, was 9.
Participants’ global insomnia scores improved over the course of the study. After accounting for age, hypnotic medication use by a quarter of participants, medication dose, and general medical comorbidity, global insomnia scores dropped on average from 6.2 at baseline to 3.7 by week 9 before increasing to 4.4 at the end of the citalopram treatment phase. This further validates the sedative effects of citalopram, the authors wrote.
Patients with more severe depression symptoms at baseline were less likely to achieve MDD remission by the end of the study. Patients with more severe insomnia at baseline were also less likely to achieve MDD remission, which was not explained by the severity of their depression. On the other hand, improved sleep was independent of MDD remission.
These findings support the notion that insomnia is not simply a symptom of MDD but a separate, co-occurring disease process, which, if true, should shift how clinicians conceptualize and treat insomnia and MDD, according to the researchers. For example, they wrote, instead of lumping together excessive sleep and insomnia as a single biological dysfunction when assessing patients with MDD, it might be better to evaluate and treat those sleep disturbances independently with targeted therapies.

Mockingbirds imitate frogs and toads across North America; they imitate at least 12 species
Mockingbirds imitate frogs and toads across North America. David E. Gammon, Anna M. Corsiglia. Behavioural Processes, October 3 2019, 103982. https://doi.org/10.1016/j.beproc.2019.103982
Highlights
• Vocal mimicry is widespread, but we know little about mimicry of non-avian models.
• Archived recordings show mockingbirds imitate at least 12 species of anurans.
• Anurans get imitated more when calls are acoustically similar to mockingbird song.
• Mockingbirds simplify anuran calls by leaving out formants and truncating calls.
Abstract: Vocal mimicry is taxonomically widespread among birds, but little is known about mimicry of non-avian models. Prior studies show preferential imitation of avian models whose sounds are acoustically similar to the non-imitative songs of the vocal mimic. Based on these studies and anecdotes about frog imitations by northern mockingbirds (Mimus polyglottos), we hypothesized which anuran models would be most likely to get imitated by mockingbirds across their geographic range. We tested our hypothesis using >40 hours of archived mockingbird recordings. Our results showed that mockingbirds imitated at least 12 anuran species, and calls were disproportionately mimicked when they contained dominant frequencies within the vocal range of the mockingbird (750-7000 Hz). Mockingbirds also frequently modified model anuran sounds by leaving out formants and/or truncating call duration. Our results represent the most comprehensive survey for any mimicking species of the imitation of anurans.

Conservatives infrahumanized all immigrants equally (and more than liberals), but liberals were more sensitive to racial/religious biases in their evaluations of immigrants
The surprising politics of anti‐immigrant prejudice: How political conservatism moderates the effect of immigrant race and religion on infrahumanization judgements. Olivia Banton, Keon West, Ellie Kinney. British Journal of Social Psychology, July 30 2019. https://doi.org/10.1111/bjso.12337
Abstract: Attitudes towards immigrants in the United Kingdom are worsening. It has been posited that these attitudes may reflect covert racial and religious prejudices, particularly among conservatives. To investigate this, two studies examined the role that immigrant race (Black/White; Study 1) and immigrant religion (Muslim/non‐Muslim; Study 2) played in immigrant infrahumanization judgements, using political conservatism as a moderating variable. There was a moderating effect of political conservatism; however, it was not in the predicted direction. The results of both studies indicated that immigrant race (Black) and immigrant religion (Muslim) predicted greater infrahumanization when political conservatism was low. Conservatives infrahumanized all immigrants equally (and more than liberals), but liberals were more sensitive to racial/religious biases in their evaluations of immigrants.

Comprehensive review of findings from neuroimaging studies investigating the relation between pubertal and functional brain development in humans
Puberty and functional brain development in humans: Convergence in findings? Junqiang Dai, K. Suzanne Scherf. Developmental Cognitive Neuroscience, Volume 39, October 2019, 100690. https://doi.org/10.1016/j.dcn.2019.100690
Abstract: Although there is a long history of studying the influence of pubertal hormones on brain function/structure in animals, this research in human adolescents is young but burgeoning. Here, we provide a comprehensive review of findings from neuroimaging studies investigating the relation between pubertal and functional brain development in humans. We quantified the findings from this literature in which statistics required for standard meta-analyses are often not provided (i.e., effect size in fMRI studies). To do so, we assessed convergence in findings within content domains (reward, facial emotion, social information, cognitive processing) in terms of the locus and directionality (i.e., positive/negative) of effects. Face processing is the only domain with convergence in the locus of effects in the amygdala. Social information processing is the only domain with convergence of positive effects; however, these effects are not consistently present in any brain region. There is no convergence of effects in either the reward or cognitive processing domains. This limited convergence in findings across domains is not the result of null findings or even due to the variety of experimental paradigms researchers employ. Instead, there are critical theoretical, methodological, and analytical issues that must be addressed in order to move the field forward.

6. Conclusion
Although
there is a long history of studying the influence of pubertal hormones
on brain function and structure in animal models (see Sisk and Zehr, 2005a, 2005b),
similar research in human adolescents is still early in its own
ontogeny. We reviewed the existing 28 studies in this field that have
been primarily conducted in the last decade. To quantify the findings,
we measured convergence in results within content domains (reward,
facial emotion, social information, cognitive processing) in terms of
the locus and directionality of effects. We report that facial emotion
processing is the only content domain with convergence in the locus of
effects, such that studies consistently find a relation between metrics
of pubertal development and neural activation in the amygdala. Social
information processing is the only content domain in which there is
consistency across studies in the directionality of effects.
Specifically, functional brain activation during a variety of social
information tasks is consistently positively associated with measures of
pubertal development in adolescents; however, these effects do not
converge in any particular locus of the brain. In contrast, there is no
convergence in the locus or directionality of effects in either the
reward or cognitive processing domains. These findings highlight
important directions for scientists to pursue in future research.
Importantly,
we reveal that this limited convergence in findings relating functional
brain and pubertal development is not because of null findings or even
the variety of experimental paradigms researchers employ. For example,
in the social information processing domain, there is immense variety in
paradigm, but convergence in the directionality of effects. In
contrast, in the reward processing domain, there is high consistency in
the experimental paradigm, and participant sample across studies, but no
convergence in locus or directionality of effects. As a result, we
argue that there are critical theoretical, methodological, and analytic
issues that must be addressed in order to move the field forward. To
tackle these issues, we suggest that this interdisciplinary work needs
to be conducted by teams of scientists with complementary expertise in
adolescent development, pubertal development, endocrinology, and
pediatric neuroimaging.
Blackouts are costing the Lebanese economy about $3.9 billion per year, or roughly 8.2 percent of the country's GDP

Excerpts about the situation in Lebanon (as Tyler Cowen mentions in his site, https://marginalrevolution.com/marginalrevolution/2019/10/the-generator-mafia-in-lebanon.html):
...blackouts are costing the Lebanese economy about $3.9 billion per year, or roughly 8.2 percent of the country's GDP.
I asked why the Lebanese government can't put the private generators out of business. He replied that EdL [the state-owned electricity company] is losing some $1.3 billion per year, while the private generators are taking in as much as $2 billion per annum. "It's a huge business," he said, "and it's very dangerous to interfere with this business."
...Nakhle, an official in the Energy Ministry, was admitting that the generator mafia bribes Lebanese politicians to make sure that EdL stays weak and blackouts persist...
Maya Ammar, a model and architect in Beirut...told me, "The one reason is Lebanon that we do not have electricity is corruption, plain and simple."...The electric grid, she continued, is "a microcosmic example of how this country runs."

• Our results are robust to various specifications.
Abstract: This paper analyzes whether education has a protective effect on mental health. To estimate causal effects, we employ an instrumental variable (IV) technique that exploits a reform extending compulsory schooling by one year implemented between 1949 and 1969 in West Germany. We complement analyses on the Mental Component Summary (MCS) score as a generic measure of overall mental health with an MCS-based indicator for risk of developing symptoms of mental health disorder and a continuous measure of subjective well-being. Results support existing evidence of a positive relationship between completed years of secondary schooling and mental health in standard OLS estimations. In contrast, the IV estimations reveal no such causal protective effect and negative effects cannot be ruled out.
Highlights

There is substantial evidence for the hypothesis that accidental disgust does not affect moral ratings, contrary to the common view
Jylkkä, Jussi, Johanna Härkönen, and Jukka Hyönä. 2019. “Accidental Disgust Does Not Cause Moral Condemnation of Neutral Actions.” PsyArXiv. October 3. doi:10.31234/osf.io/b26vz
Abstract: Emotivism in moral psychology holds that making moral judgements is at least partly an affective process. Three emotivist hypotheses can be distinguished: the elicitation hypothesis (that moral transgressions elicit emotions); the amplification hypothesis (that disgust amplifies moral judgments); and the moralization hypothesis (that affect moralizes the non-moral). Even though the moralization hypothesis is the strongest and most radical form of emotivism, it has not been systematically experimentally tested. Most previous studies have used as stimuli morally wrong actions, and thus they cannot answer whether disgust is sufficient to moralize an otherwise neutral action. In Experiment 1 (N = 87) we tested the effect of accidental disgust on morally neutral scenarios, and in Experiment 2 (N = 510) the differential effect of disgust on neutral and wrong scenarios. The results did not support either the moralization or the amplification hypothesis. Instead, Bayesian analyses provided substantial evidence for the null hypothesis that accidental disgust does not affect moral ratings. In line with a recent meta-analysis suggesting that disgust has no effect on moral ratings, our study indicates that this field of research is plagued by false positives due to small sample sizes.

First description of “wealth” inequality in an animal (hermit crabs), which may provide an animal model of the dynamics generating wealth inequality
A comparison of wealth inequality in humans and non-humans. Ivan D. Chase, Raphael Douady, Dianna K. Padilla. Physica A: Statistical Mechanics and its Applications, September 26 2019, 122962. https://doi.org/10.1016/j.physa.2019.122962
Highlights
• We present the first description of “wealth” inequality in a non-human animal.
• We describe the distribution of snail shells occupied by a hermit crab species.
• The distribution of shells resembles the common form of human wealth distributions.
• Hermit crabs may provide an animal model of the dynamics generating wealth inequality.
• Shell distribution in hermit crabs provides a baseline to compare to human inequality.
Abstract: Inequality in the distribution of material resources (wealth) occurs widely across human groups. The extent of inequality, as measured by the Gini coefficient, is less in small-scale societies, such as hunter-gatherers and pastoralists, and greater in large-scale ones like current nation states. In many societies, the statistical distribution of wealth takes a characteristic form: unimodal, skewed to the right, and fat-tailed. However, we have relatively little systematic information about the distribution of material resources in nonhuman animals even though such resources are vital to their survival and fitness. Here we present the first description of inequality in material resources in an animal population: the distribution of gastropod (snail) shells inhabited by the hermit crab Pagurus longicarpus. We find that the shell distribution for the crabs strongly resembles the characteristic form of wealth distribution in human groups. The amount of inequality in the crabs is more than that in some small-scale human groups but less than that in nations. We argue that the shell distribution in the crabs is not simply generated by biological factors such as survival and growth of either crabs or gastropods. Instead, the strong resemblance in the human and hermit crab distributions suggests that comparable factors, not dependent upon culture or social institutions, could shape the patterns of inequality in both groups. In addition to the similarity in their inequality distributions, human and hermit crabs share other features of resource distribution, including the use of vacancy chains, not seen in other species. Based upon these parallels, we propose that P. longicarpus could be used as an animal model to test two factors – individual differences and intergenerational property transfers – that some economists theorize as major factors influencing the form of wealth distributions in humans. We also propose that inequality in hermit crabs could provide a baseline for examining human inequality.

From 2018... Salutogenic effects of adversity and the role of adversity for successful aging
From 2018...Salutogenic effects of adversity and the role of adversity for successful aging. Jan Höltge. Fall 2018, University of Zurich, Faculty of Arts, PhD Thesis. https://www.zora.uzh.ch/id/eprint/157239/1/157239.pdf
Abstract
The traditional psychopathological research of adversity has led to a deficit-and treatment-oriented approach to adversity and its effects. However, even though adversities are distressing, negative experiences in the first place, they also inherit resilience and well-being enhancing opportunities which can foster a more fulfilled life. This thesis synthesizes research on the salutogenic effects of adversityand provides empirical evidence for salutogenic effects of different levels of adversity. A mixed-methods project that consisted of a theoretical study, a quantitative longitudinal survey and qualitative interview study was conducted. Its aims were to review the research on ‘optimal’ adversity, andto investigate the potential positive psychological effects of severe early-life and ‘optimal’ later-life adversityfor successful aging.
The first study systematically reviewed the literature on a potential ‘optimal’ level of adversity for human well-being and development using curvilinear analyses. A moderate level of adversity was found to be associated with better outcomes compared to higher and lower levels of adversity. The second study investigated potential age-specific salutogenic effects of ‘optimal’ adversity in later life. It was found that a specific level of adverse experiences can support successful aging by supporting the maintenance of central resilience resources and satisfaction with life. The third study investigated if a subgroup of the Swiss Verdingkinder (former indentured child laborers) was able to age successful not despite, but because of its childhood experiences. Three overall factors emerged that were reported as supportive of successful aging: lightheartedness including effective stress-management, lifelong self-enhancement, and social mindedness. Hence, this study shows that known supportivefactors of successful aging can be the result of early-life adversity. Several underlying mechanisms and intervening factors of this relationship were identified.
In sum,this thesis gives further evidence for the salutogenic effects of adversity and provides implications for future research and praxis.
Check also Research has predominantly focused on the negative effects of adversity on health and well-being; but under certain circumstances, adversity may have the potential for positive outcomes, such as increased resilience and thriving (steeling effect):

Firm-level data for 55 countries, 1991-2016: The riskiness of credit allocation, captured by Greenwood and Hanson (2013)’s ISS indicator, helps predict downside risks to GDP growth & systemic banking crises 2-3 years ahead
Working Paper No. 19/207 : The Riskiness of Credit Allocation and Financial Stability. Luis Brandao-Marques,Qianying Chen,Claudio Raddatz,Jérôme Vandenbussche,Peichu Xie. IMF Working Paper No. 19/207, September 27, 2019. https://www.imf.org/en/Publications/WP/Issues/2019/09/27/The-Riskiness-of-Credit-Allocation-and-Financial-Stability-48670
Summary: We explore empirically how the time-varying allocation of credit across firms with heterogeneous credit quality matters for financial stability outcomes. Using firm-level data for 55 countries over 1991-2016, we show that the riskiness of credit allocation, captured by Greenwood and Hanson (2013)’s ISS indicator, helps predict downside risks to GDP growth and systemic banking crises, two to three years ahead. Our analysis indicates that the riskiness of credit allocation is both a measure of corporate vulnerability and of investor sentiment. Economic forecasters wrongly predict a positive association between the riskiness of credit allocation and future growth, suggesting a flawed expectations process.

Despite the apparent irrationality of over-imitation behavior, should be conceptualized as a contextually flexible and, in fact, a normally highly functional phenomenon
‘Over-imitation’: A review and appraisal of a decade of research. Stefanie Hoehl et al. Developmental Review, Volume 51, March 2019, Pages 90-108. https://doi.org/10.1016/j.dr.2018.12.002
Highlights
• We offer a comprehensive review of the existing literature on over-imitation.
• We discuss methodological issues affecting the behavior in experiments.
• Different theoretical perspectives are contrasted and critically assessed.
• Over-imitation is a contextually flexible and normally functional phenomenon.
Abstract: After seeing an action sequence children and adults tend to copy causally relevant and, more strikingly, even perceivably unnecessary actions in relation to the given goal. This phenomenon, termed “over-imitation”, has inspired much empirical research in the past decade as well as lively theoretical debate on its cognitive underpinnings and putative role in the transmission of cultural knowledge. Here, we offer a comprehensive review of the existing literature to date, accompanied by a table including concise information on 54 published studies testing over-imitation in different species, age groups and cultures. We highlight methodological issues related to task and context that influence over-imitation rates and that should be carefully considered in study designs. We discuss the cognitive and motivational processes underlying and contributing to over-imitation, including normative action parsing, causal reasoning, motives of affiliation and social learning as well as their complex interplay. We conclude that despite the apparent irrationality of over-imitation behavior, recent studies have shown that its performance depends on the specific task, modeled actions and context variables, suggesting that over-imitation should be conceptualized as a contextually flexible and, in fact, a normally highly functional phenomenon.

Vegetarian products are perceived as being less caloric than their non-vegetarian equivalents, but participants in the study do not report more intention to eat more vegetarian products
Halo It’s Meat! the Effect of the Vegetarian Label on Calorie Perception and Food Choices. Théo Besson, Hugo Bouxom & Thibault Jaubert. Ecology of Food and Nutrition, Aug 26 2019. https://doi.org/10.1080/03670244.2019.1652820
ABSTRACT: In the last few years, vegetarian products have become a widespread dietary option in food industry to the point that large retail chains such as McDonald’s has offered a vegetarian burger to their customers (e.g., the Grand Veggie). In the present research, two studies investigated the influence of a vegetarian label on calorie perception, frequency consumption and food choices. In the first study (N = 211) participants were randomly assigned to an experimental design 2 (burger type: Grand Veggie vs Big Mac). In the second study (N = 915), participants were either exposed to a similar burger labeled vegetarian or a meat-based. Both studies show that vegetarian products are perceived as being less caloric than their non-vegetarian equivalents. However, participants do not report more intention to eat more vegetarian products and do not lead to differences in menu composition.

Parenting quality is most optimal when fathers’ testosterone system reacts in the expected direction given the context of the father-child interaction: a T decrease/increase during a harmonious/challenging interaction
Testosterone and Fathers’ Parenting Unraveled: Links with the Quantity and Quality of Father-Child Interactions. Else E. de Vries et al. Adaptive Human Behavior and Physiology, October 2 2019. https://link.springer.com/article/10.1007/s40750-019-00118-z
Abstract
Objective: Individual differences in quality of father involvement in caregiving might in part be explained by fathers’ testosterone (T) levels. We examined the links between fathers’ (n = 32) salivary T levels, amount of time spent with their child (12–30 months of age), type of father-child interaction, and fathers’ sensitivity.
Methods: During two home visits, video observations of father-child interactions were conducted to measure fathers’ sensitivity during a challenging and harmonious interaction. Fathers’ saliva was collected several times throughout the day on a working day and on the home visit days, including right before and after each father-child interaction.
Results: Fathers’ T secretion throughout the day was lower on home visit days (i.e., days with a higher amount of time spent with their child) than on a working day. For both challenging and harmonious father-child interactions, mean T levels did not differ before and after father-child interactions. However, individual changes in fathers’ T levels during the father-child interactions did predict fathers’ sensitivity. Specifically, the more T increased during the challenging interaction, or decreased during the harmonious interaction, the more sensitive the father was during that interaction as well as during a subsequent interaction.
Conclusions: Parenting quality is most optimal when fathers’ T system reacts in the expected direction given the context of the father-child interaction, i.e., a T decrease during a harmonious interaction and a T increase during a challenging interaction. Our study underscores the importance of examining the interplay between biology, behavior, and caregiving context in fathers’ parenting.

Self-enhancement, the motive to view oneself in positive light: Not only are heritable its manifestations at the subjective & intermediate level, but also are the objective level & its relation with psychological well-being
On the Etiology of Self-Enhancement and Its Association With Psychological Well-Being. Yu L. L. Luo, Constantine Sedikides, Huajian Cai. Social Psychological and Personality Science, September 30, 2019. https://doi.org/10.1177/1948550619877410
Abstract: Self-enhancement, the motive to view oneself in positive light, and its manifestations have received wide attention in behavioral sciences. The self-enhancement manifestations vary on a continuum from a subjective level (agentic narcissism, communal narcissism, narcissistic grandiosity) through an intermediate level (better-than-average judgments) to an objective level (overclaiming one’s knowledge). Prior research has established the heritability of self-enhancement manifestations at the subjective and intermediate levels. The present twin study demonstrated that (1) the objective level of self-enhancement manifestation is also heritable; (2) a common core, which is moderately heritable, underlies the three levels of self-enhancement manifestations; (3) the relation between self-enhancement (manifested at all three levels) and psychological well-being is partly heritable; and (4) environmental influences, either shared by or unique to family members, are evident through (1), (2), and (3). The findings deepen understanding of the etiology of individual differences in self-enhancement and their links to psychological well-being.

The existence of female orgasm is intriguing: On the one hand, female orgasm is not necessary for female reproductive success, & on the other hand, this neuro-endocrine reflex is too complex to be an evolutionary accident
An experimental test of the ovulatory homolog model of female orgasm. Mihaela Pavlicev, Andreja Moset Zupan, Amanda Barry, Savannah Walters, Kristin M. Milano, Harvey J. Kliman, and Günter P. Wagner. Proceedings of the National Academy of Sciences, September 30, 2019. https://doi.org/10.1073/pnas.1910295116
Significance: The existence of female orgasm is intriguing for 2 reasons: On the one hand, female orgasm is not necessary for female reproductive success, and on the other hand, this neuro-endocrine reflex is too complex to be an evolutionary accident. This led to many proposed evolutionary explanations, most of which have little empirical support. We previously proposed that female orgasm uses a mechanism that originated for inducing ovulation during copulation: A mechanism that still exists in many animals but lost its role in others. Here we provide experimental evidence, strengthening the likelihood that female orgasm evolved from copulation-induced ovulation. This finding helps interpreting otherwise difficult to explain aspects of female sexuality, such as the low rate of female orgasm during intercourse.
Abstract: The ovulatory homolog model of female orgasm posits that the neuro-endocrine mechanisms underlying female orgasm evolved from and are homologous to the mechanisms mediating copulation-induced ovulation in some mammals. This model predicts that pharmacological agents that affect human orgasm, such as fluoxetine, should also affect ovulation in animals with copulation-induced ovulation, such as rabbits. We tested this prediction by treating rabbits with daily doses of fluoxetine for 2 wk and found that fluoxetine treatment reduces the number of ovulations postcopulation by 30%. In a second experiment we tested whether this result was mediated by an effect on the brain or via peripheral serotonin functions. We treated animals with fluoxetine and induced ovulation with a single injection of human chorionic gonadotropin. In this experiment ovulation rate was nominally reduced by only 8%, which is statistically not significant. We conclude that the effect of fluoxetine on copulation-induced ovulation rate supports the ovulatory homolog model of female orgasm, suggesting that female orgasm has very deep evolutionary roots among the early eutherian mammals.

From 2016... Not only bilateral trade but global trade openness also significantly promotes peace
From 2016... Does Trade Integration Contribute to Peace? Jong‐Wha Lee, Ju Hyun Pyun. Review of Development Economics, January 28 2016. https://doi.org/10.1111/rode.12222
Abstract: We investigate the effect of trade integration on interstate military conflict. Our empirical analysis, based on a large panel data set of 243,225 country‐pair observations from 1950 to 2000, confirms that an increase in bilateral trade interdependence significantly promotes peace. It also suggests that the peace‐promotion effect of bilateral trade integration is significantly higher for contiguous countries that are likely to experience more conflict. More importantly, we find that not only bilateral trade but global trade openness also significantly promotes peace. It shows, however, that an increase in global trade openness reduces the probability of interstate conflict more for countries far apart from each other than it does for countries sharing borders. The main finding of the peace‐promotion effect of bilateral and global trade integration holds robust when controlling for the simultaneous determination of trade and peace.

Patients with Lesions to Left Prefrontal Cortex Have Less Entrenched Beliefs and Are More Skeptical Reasoners
Patients with Lesions to Left Prefrontal Cortex (BA 9 and BA 10) Have Less Entrenched Beliefs and Are More Skeptical Reasoners. Vinod Goel, Miriam Marling, Vanessa Raymont, Frank Krueger and Jordan Grafman. Journal of Cognitive Neuroscience. Volume 31, Issue 11, November 2019, p.1674-1688. https://doi.org/10.1162/jocn_a_01441
Abstract: The effect of prior beliefs on reasoning and decision-making is a robust, poorly understood phenomenon, exhibiting considerable individual variation. Neuroimaging studies widely show the involvement of the left pFC in reasoning involving beliefs. However, little patient data exist to speak to the necessity and role of the left pFC in belief-based inference. To address this shortcoming, we tested 102 patients with unilateral focal penetrating traumatic brain injuries and 49 matched controls. Participants provided plausibility ratings (plausible/implausible) to simple inductive arguments and (separately) strength of believability ratings of the conclusion to those same arguments. A voxel-based lesion symptom mapping analysis identified 10 patients, all with lesions to the left pFC (BA 9 and BA 10) as rating significantly fewer arguments with highly believable conclusions as “plausible,” compared with all other patients. Subsequent analyses, incorporating the right hemisphere homologue of these patients (n = 12) and normal controls (n = 24), revealed patients with lesions to left pFC found fewer arguments plausible in the high believable than either of these groups, and there was no difference in the behavioral scores of the right pFC patients and normal controls. Further analysis, utilizing the belief ratings as the dependent measure, revealed a Group × Belief Rating interaction, with left pFC patients having less intense beliefs about the conclusions of moderately believable and highly believable arguments. We interpreted these results to indicate that lesions to left pFC (BA 9, BA 10) increase incredulity and make these patients more skeptical reasoners. The former can partially, but not fully, explain the latter. The other relevant factor may be that unilateral left pFC lesions disrupt hemispheric equilibrium and allow for an increased inhibitory role of the right pFC. We speculate that individual differences in belief bias in reasoning in the normal population may be a function of individual differences in the left and right pFC interactional dynamics.
Abstract: The effect of prior beliefs on reasoning and decision-making is a robust, poorly understood phenomenon, exhibiting considerable individual variation. Neuroimaging studies widely show the involvement of the left pFC in reasoning involving beliefs. However, little patient data exist to speak to the necessity and role of the left pFC in belief-based inference. To address this shortcoming, we tested 102 patients with unilateral focal penetrating traumatic brain injuries and 49 matched controls. Participants provided plausibility ratings (plausible/implausible) to simple inductive arguments and (separately) strength of believability ratings of the conclusion to those same arguments. A voxel-based lesion symptom mapping analysis identified 10 patients, all with lesions to the left pFC (BA 9 and BA 10) as rating significantly fewer arguments with highly believable conclusions as “plausible,” compared with all other patients. Subsequent analyses, incorporating the right hemisphere homologue of these patients (n = 12) and normal controls (n = 24), revealed patients with lesions to left pFC found fewer arguments plausible in the high believable than either of these groups, and there was no difference in the behavioral scores of the right pFC patients and normal controls.

The anterior cingulate cortex is an important cognitive control area for both sexually arousing and disgust stimuli; the activation of the thalamus may indicate a general automatic response towards sexual disgust
Long, Xipeng and Tian, Fangfang and Zhou, Yushan and Cheng, Bochao and Yi, Siqi and Jia, Zhiyun, The Neural Correlates of Sexual Arousal and Sexual Disgust (September 23, 2019). SSRN: https://ssrn.com/abstract=3458493
Abstract
Background: Humans exhibit category-specific networks of activity when viewing sexual stimuli. The differences and relationships between stimulus-related brain activation for sexual arousal and sexual disgust are still unclear. This study aimed to identify brain regions that were mostly associated with sexual stimuli.
Methods: A systematic search was performed to identify fMRI studies that reported brain activity during sexual stimuli. The activation foci were subjected to meta-analysis using the activation likelihood estimation (ALE) method. Subsequently, meta-analytic connectivity modelling (MACM) was used to create a model for the core brain network involved in responses to sexual stimuli. The functional properties of the network were assessed using behavioural domain (BD) metadata in the BrainMap database.
Findings: An ALE meta-analysis of a total of 368 subjects showed that sexual stimuli are related to the extensive activation of the occipital-temporal-limbic system and less extensive activation of the basal ganglia. Sexual arousal activated mainly the anterior cingulate cortex and right fusiform gyrus, while sexual disgust activated the limbic system, occipital gyrus, and thalamus. MACM analysis showed a network of the core brain areas involved in response to sexual stimuli, and behavioural domain analysis indicated that these areas have both common and discrete functional properties.
Interpretation: Our findings suggested that the anterior cingulate cortex is an important cognitive control area for both sexually arousing and disgust stimuli. The activation of the thalamus may indicate a general automatic response towards sexual disgust. These results revealed consistent coactivation maps across experiments and behaviours for convergent areas.

Liberals express compassion toward less structured & more encompassing entities (friends, world), whereas conservatives express compassion toward more well-defined & less encompassing entities (family, nation)
Ideological differences in the expanse of the moral circle. Adam Waytz, Ravi Iyer, Liane Young, Jonathan Haidt & Jesse Graham. Nature Communications, volume 10, Article number: 4389 (2019). https://www.nature.com/articles/s41467-019-12227-0
Abstract: Do clashes between ideologies reflect policy differences or something more fundamental? The present research suggests they reflect core psychological differences such that liberals express compassion toward less structured and more encompassing entities (i.e., universalism), whereas conservatives express compassion toward more well-defined and less encompassing entities (i.e., parochialism). Here we report seven studies illustrating universalist versus parochial differences in compassion. Studies 1a-1c show that liberals, relative to conservatives, express greater moral concern toward friends relative to family, and the world relative to the nation. Studies 2a-2b demonstrate these universalist versus parochial preferences extend toward simple shapes depicted as proxies for loose versus tight social circles. Using stimuli devoid of political relevance demonstrates that the universalist-parochialist distinction does not simply reflect differing policy preferences. Studies 3a-3b indicate these universalist versus parochial tendencies extend to humans versus nonhumans more generally, demonstrating the breadth of these psychological differences.
Introduction
In 2006, then Democratic Senator Barack Obama bemoaned the country’s “empathy deficit,” telling college graduates, “I hope you choose to broaden, and not contract, your ambit of concern.” In 2012, Republican presidential challenger Mitt Romney said, “President Obama promised to begin to slow the rise of the oceans and heal the planet. My promise is to help you and your family.”
The distinction between Obama and Romney captures the distinct worldviews of American political liberals and conservatives, respectively. Romney prioritized the family unit, whereas Obama highlighted the planet broadly. This difference in parochialism versus universalism became exacerbated during the 2016 presidential election, with one article noting, “Trump vs. Hillary Is Nationalism vs. Globalism, 20161,” contrasting the more parochial Republican candidate with the more universalist Democratic candidate. Others have characterized the Trump administration’s policy decisions as battles between nationalists (typified by parochialism) and globalists (typified by universalism)2.
These differential tendencies toward parochialism and universalism on the political right and left, respectively, extend beyond the United States as well. For example, leading French right-wing politician, Marie Le Pen declared in 2016, “The gap is not between the Left and the Right, but between globalists and patriots. The globalists are acting for the dilution of France and its people in a huge worldwide magma. The patriots hope that the nation constitutes the most protective space for the French3.” Across Western Europe, ideological battles between the left and right have centered on this tension between universalism and parochialism.
Universalism refers to moral regard directed toward more socially distant and structurally looser targets, relative to socially closer and structurally tighter targets. Parochialism refers to moral regard directed toward socially closer and structurally tighter targets, relative to socially more distant and structurally looser targets. Universalist moral circles and parochial moral circles in this context are concentric, with one encompassing the other. These circles refer to groups of targets toward which one expends moral regard, and reflect the concept of moral circles popularized by Singer4 (see also Burke5). They are akin to the idea of moral communities that comprise one’s in groups (discussed by Deutsch et al.6,7), in which entities can be included or excluded as worthy of moral regard, as well as to concentric circles of identity defined by self-categorization theory (whereby one’s self-concept can include increasingly distant social groups depending on one’s level of abstraction)8. While “parochial” sometimes has a negative connotation, we do not imply any such evaluation here and simply use it to describe maintaining a tight (versus loose) moral circle.
Previous research supports this universalist–parochial distinction between liberals and conservatives9. For instance, conservatives, relative to liberals, express greater need for closure, order, and structure10,11,12. Personality research shows social liberals consistently score higher on openness, whereas social conservatives score higher on conscientiousness13. Taken together, existing work suggests that political conservatism reflects a greater tendency to seek structure, to avoid ambiguity, changes to the status quo, and novelty. By this account, political liberalism represents greater comfort with lack of structure, new experiences, and novel information.
Given ideological differences in open versus closed styles of information processing, moral concern might follow a similar pattern. In prioritizing closure, order, and stability, conservatives should express concern toward smaller, more well-defined, and less permeable social circles (relative to broader ones). In prioritizing openness, tolerance for ambiguity, and desire for change, liberals should express concern toward larger, less well-defined, and more permeable social circles (relative to smaller ones).
Beyond low-level cognitive and motivational differences, one additional line of work supports the ideological distinction between parochial–universalist differences in compassion. This line of research stems from Moral Foundations Theory (MFT)14,15,16, which characterizes liberals and conservatives as diverging along two classes of intuitive moral values. Liberals care about harm and fairness (individualizing values), whereas conservatives care more about loyalty, authority, and sanctity (binding values). This research again suggests a differing focus such that liberals tend to express compassion toward individuals broadly construed, whereas conservatives emphasize compassion toward their immediate social groups. Supporting this idea, separate work indeed found that endorsement of individualizing values is positively correlated with moral expansiveness (moral consideration for entities, including plants and animals, beyond one’s immediate in group) whereas endorsement of binding values is negatively correlated with moral expansiveness17.
The present research provides empirical evidence for these differing ideological patterns of compassion and extends these patterns to stimuli across a range of measures. This work also shows these broader ideological differences are rooted in perceptual differences. These differences appear to stem also from a broader historical trend that has accelerated in recent decades as most countries have become wealthier and safer. Christian Welzel, a lead researcher for the World Values Survey, has described how reduced “existential threats” change values:
These studies aim to connect Singer’s4 idea of the moral circle to empirical political psychology. Beyond demonstrating a universalist–parochial distinction between liberals and conservatives, this research examines whether this distinction reflects mere political preferences, or something deeper. Universalism may reflect favorability toward policies that promote open borders (and encourage immigration) and that promote diplomacy toward ostensibly hostile nations. Such policies represent extending moral regard beyond one’s immediate group (e.g., the nation) and to the world more broadly. Similarly, parochialism may reflect favorability toward stricter immigration policies and defense spending to protect one’s nation—these policies represent prioritizing the well-being of one’s own nation at the potential expense of others. On the other hand, if the universalist–parochial distinction reflects a worldview beyond policy interests, then it should reflect evaluations of stimuli completely devoid of social or political relevance, for example abstract, animate shapes. Thus, we tested whether liberals and conservatives would display universalist and parochialist tendencies, respectively, in terms basic perceptual preferences. Finally, we examined whether this universalist–parochialist difference would map on to moral concern for humans exclusively versus a broader conception of the moral universe that includes nonhumans as well. Importantly, this work uses both measures developed for this work that explicitly capture the expanse of one’s moral circle as well as established measures that assess moral consideration for specific targets, to provide convergent evidence across studies.
Studies 1a–1c examine universalist versus parochial differences in the domains of friends versus family (friends typically constitute a larger, broader and more diffuse group than family) and the world versus the nation (the world encompasses one’s nation). Studies 2a–2b show this universalist–parochial distinction maps on to abstract entities (animated shapes) distinguished only by low-level perceptual properties. Studies 3a–3b demonstrate that this universalist–parochial distinction maps on to moral concern for humans exclusively compared with a social world that includes nonhumans. Across studies, we predicted that liberalism versus conservatism would be associated with universalism relative to parochialism, even in the context of preference for shapes devoid of social relevance and humans versus nonhumans.

Fading existential pressures open people’s minds, making them prioritize freedom over security, autonomy over authority, diversity over uniformity, and creativity over discipline… the existentially relieved state of mind is the source of tolerance and solidarity beyond one’s in group18.Our research is consistent with Welzel’s characterization of the general shift from “survival values” that increase dependence on close others, to “emancipative values” that downplay local ties—and loyalties—and lead people to look farther afield for social relationships.

We often judge that old objects or objects used by admired celebrities are worth less when cleaned, possible because cleaning removes valued historical traces, and by changing objects from their historic state
The glow of grime: Why cleaning an old object can wash away its value. Merrick Levene Daisy Z. Hu Ori Friedman. Judgment and Decision Making, Vol. 14, No. 5, September 2019, pp. 565-572. http://journal.sjdm.org/18/181204/jdm181204.html
Abstract: For connoisseurs of antiques and antiquities, cleaning old objects can reduce their value. In five experiments (total N = 1,019), we show that lay people also often judge that old objects are worth less when cleaned, and we test two explanations for why cleaning can reduce object value. In Experiment 1, participants judged that cleaning an old object would reduce its value, but judged that cleaning would not reduce the value of an object made from a rare material. In Experiments 2 and 3 we described the nature, age and origin of the traces that cleaning would remove. Now participants judged that cleaning old historical traces would reduce the object’s value, but cleaning recently acquired traces would not. In Experiment 4, participants judged that the current value of an old object is reduced even when it was cleaned in ancient times. However, participants in Experiment 5 valued objects cleaned in ancient times as much as uncleaned ones, while judging that objects cleaned recently are worth less. Together, our findings suggest that cleaning objects may reduce value by removing valued historical traces, and by changing objects from their historic state. We also outline potential implications for previous studies showing that cleaning reduces the value of objects used by admired celebrities.

False information can have short-term effects on what we believe & how we behave politically following exposure, which may be minimal, despite the countervailing narrative in the popular press
What’s Next? Six Observations for the Future of Political Misinformation Research. Brian E. Weeks, Homero Gil de Zúñiga. American Behavioral Scientist, September 30, 2019. https://doi.org/10.1177/0002764219878236
Abstract: Research on political misinformation is booming. The field is continually gaining more key insights about this important and complex social problem. Academic interest on misinformation has consistently been a multidisciplinary effort. But perhaps political communication researchers are particularly well situated to be the leading voices on the public’s understanding of misinformation and many are heeding the call. With that responsibility in mind, in this brief article we offer six observations for the future of political misinformation research that we believe can help focus this line of inquiry to better ensure we address some of the most pressing problems. Our list is not exhaustive, nor do we suggest that areas we do not cover are not important. Rather, we make these observations with the goal of spurring a conversation about the future of political misinformation research.

Intelligence of males and females were underpinned by different neurobiological correlates, which are consistent with their respective superiority in cognitive domains (visuospatial vs verbal ability)
Gender Differences in Connectome-based Predictions of Individualized Intelligence Quotient and Sub-domain Scores. Rongtao Jiang et al. Cerebral Cortex, bhz134, July 29 2019. https://doi.org/10.1093/cercor/bhz134
Abstract: Scores on intelligence tests are strongly predictive of various important life outcomes. However, the gender discrepancy on intelligence quotient (IQ) prediction using brain imaging variables has not been studied. To this aim, we predicted individual IQ scores for males and females separately using whole-brain functional connectivity (FC). Robust predictions of intellectual capabilities were achieved across three independent data sets (680 subjects) and two intelligence measurements (IQ and fluid intelligence) using the same model within each gender. Interestingly, we found that intelligence of males and females were underpinned by different neurobiological correlates, which are consistent with their respective superiority in cognitive domains (visuospatial vs verbal ability). In addition, the identified FC patterns are uniquely predictive on IQ and its sub-domain scores only within the same gender but neither for the opposite gender nor on the IQ-irrelevant measures such as temperament traits. Moreover, females exhibit significantly higher IQ predictability than males in the discovery cohort. This findings facilitate our understanding of the biological basis of intelligence by demonstrating that intelligence is underpinned by a variety of complex neural mechanisms that engage an interacting network of regions—particularly prefrontal–parietal and basal ganglia—whereas the network pattern differs between genders.

Randomness and related concepts (events happening “accidentally”, “coincidentally” or “by chance”) are typically assumed to occur in a context of small rather than large events
Are random events expected to be small? Karl Halvor TeigenAlf Børre Kanten. Psychological Research, September 30 2019. https://link.springer.com/article/10.1007/s00426-019-01252-9
Abstract: People’s intuitions about mathematical and statistical concepts often include features that are not a part of the formal definitions. We argue that randomness and related concepts (events happening “accidentally”, “coincidentally” or “by chance”) are typically assumed to occur in a context of small rather than large events. Five experiments were designed to test the hypothesis of an association between perceived randomness and size. In Experiment 1 and 2, statements describing small outcomes as due to chance were judged to be more natural and to make better sense than corresponding statements about large outcomes (or about small outcomes not due to chance). Experiment 3 showed that people imagine that stories about randomness in daily life should preferably start with small events, even when they eventually turn out to be consequential (e.g., stories about an apparently random meeting ending with marriage). Experiment 4 demonstrated that small changes in a graph of a random walk were seen as random, whereas large changes were perceived as potentially nonrandom. Finally, Experiment 5 showed that small animals are believed to display more random behavior than larger ones. This applied also to fictional creatures with nonsense names, where size was implicitly suggested by the names’ phonetic qualities. Analogical instances can be found in the history of science, all the way back to Lucretius’ doctrine of the tiny “swerves” of atoms. The pervasive association between smallness and randomness might be partly due to real-world observations and partly to cognitive and motivational constraints.

90 countries, 45 years of analysis: Financial repression (restrictions on interest rates, credit allocation, capital movements, etc.) poses a significant drag on growth, 0.4-0.7 percentage points
Financial Repression is Knocking at the Door, Again. Etibar Jafarov,Rodolfo Maino,Marco Pani. IMF Working Paper No. 19/211. https://www.imf.org/en/Publications/WP/Issues/2019/09/30/Financial-Repression-is-Knocking-at-the-Door-Again-48641
Summary: Financial repression (legal restrictions on interest rates, credit allocation, capital movements, and other financial operations) was widely used in the past but was largely abandoned in the liberalization wave of the 1990s, as widespread support for interventionist policies gave way to a renewed conception of government as an impartial referee. Financial repression has come back on the agenda with the surge in public debt in the wake of the Global Financial Crisis, and some countries have reintroduced administrative ceilings on interest rates. By distorting market incentives and signals, financial repression induces losses from inefficiency and rent-seeking that are not easily quantified. This study attempts to assess some of these losses by estimating the impact of financial repression on growth using an updated index of interest rate controls covering 90 countries over 45 years. The results suggest that financial repression poses a significant drag on growth, which could amount to 0.4-0.7 percentage points.
Summary: Financial repression (legal restrictions on interest rates, credit allocation, capital movements, and other financial operations) was widely used in the past but was largely abandoned in the liberalization wave of the 1990s, as widespread support for interventionist policies gave way to a renewed conception of government as an impartial referee. Financial repression has come back on the agenda with the surge in public debt in the wake of the Global Financial Crisis, and some countries have reintroduced administrative ceilings on interest rates. By distorting market incentives and signals, financial repression induces losses from inefficiency and rent-seeking that are not easily quantified. This study attempts to assess some of these losses by estimating the impact of financial repression on growth using an updated index of interest rate controls covering 90 countries over 45 years.

Children of divorced parents are less honest than children of non-divorced parents; psychological counseling improves their honesty, and fails to improve children of non-divorced parents
Parents’ marital status, psychological counseling and dishonest kindergarten children: An experimental study. Yossef Tobol, Gideon Yaniv. Journal of Economic Behavior & Organization, September 30 2019. https://doi.org/10.1016/j.jebo.2019.09.012
Highlights
• An experiment with kindergarten children is conducted to reveal their level of honesty.
• Children of divorced parents are less honest than children of non-divorced parents.
• Psychological counseling improves honesty of children of divorced parents.
• Psychological counseling fails to improve honesty of children of non-divorced parents.
Abstract: The present paper reports the results of an experiment which studied the effects of parents’ marital status (divorced or non-divorced) and psychological counseling (administered or not) on the honesty level of kindergarten children. Data on marital status and psychological counseling was anonymously provided by the kindergarten teachers and children's level of honesty was assessed by a flip-coin task which rewarded a self-reported favorable outcome. The experiment gave rise to two major results: first, children of divorced parents are less honest than children of non-divorced parents and second, psychological counseling helps improve honesty among children of divorced parents but fails to do so among children of non-divorced parents. No gender effect was found.

Growth has been good after reform in Africa and Latin America, in contrast to the “lost decades” of the 80s and 90s
In Search of Reforms for Growth: New Stylized Facts on Policy and Growth Outcomes. William Easterly. NBER Working Paper No. 26318, September 2019. https://www.nber.org/papers/w26318
Abstract: The lack of growth response to “Washington Consensus” policy reforms in the 1980s and 1990s led to widespread doubts about the value of such reforms. This paper updates these stylized facts by analyzing moderate to extreme levels of inflation, black market premiums, currency overvaluation, negative real interest rates and abnormally low trade shares to GDP. It finds three new stylized facts: (1) policy outcomes worldwide have improved a lot since the 1990s, (2) improvements in policy outcomes and improvements in growth across countries are correlated with each other (3) growth has been good after reform in Africa and Latin America, in contrast to the “lost decades” of the 80s and 90s. This paper makes no claims about causality. However, if the old stylized facts on disappointing growth accompanying reforms led to doubts about economic reforms, new stylized facts should lead to some positive updating of such beliefs.

Gluten aversion is not limited to the political left; perhaps most surprising, supporters of Donald Trump are more likely to identify as avoiding gluten, relative to non-supporters
Gluten aversion is not limited to the political left. Trey Malone, F. Bailey Norwood. Agriculture and Human Values, June 20 2019. https://link.springer.com/article/10.1007/s10460-019-09958-7
Abstract: Despite a heightened political discourse surrounding food choices, few studies have identified connections between political beliefs and consumer perceptions. Using gluten as an example, this article identifies how political opinions relate to opinions of food products. If an avoidance of gluten is a biological condition and not a social construct, there should be no correlation between political opinions and gluten avoidance. Our study uncovers a complex relationship between the social construction of gluten avoidance and the potential role of political views. Perhaps most surprising, we find that supporters of Donald Trump are more likely to identify as avoiding gluten, relative to non-supporters. Findings suggest that future research might benefit from considering the political beliefs of consumers when estimating models of food demand.

From 2018... Overestimating democracy, despite its absence, is widespread in less developed countries with little or no democratic tradition; underestimating is common in mature, economically developed, Protestant democracies
From 2018... Democracy Confused: When People Mistake the Absence of Democracy for Its Presence. Stefan Kruse, Maria Ravlik, Christian Welzel. Journal of Cross-Cultural Psychology, December 31, 2018. https://doi.org/10.1177/0022022118821437
Abstract: A widely neglected phenomenon consists in the fact that large population segments in many countries confuse the absence of democracy with its presence. Significantly, these are also the countries where widespread support for democracy coexists with persistent deficiencies in the latter, including its outright absence. Addressing this puzzle, we introduce a framework to sort out to what extent national populations overestimate their regimes’ democratic qualities. We test our hypotheses applying multilevel models to about 93,000 individuals from 75 countries covered by the cross-cultural World Values Surveys. We find that overestimating democracy is a widespread phenomenon, although it varies systematically across countries. Among a multitude of plausible influences, cognitive stimuli and emancipative values work together as a psychologically activating force that turns people against overestimating democracy. In fact, this psychological activation not only reduces overestimations of democracy; it actually leads toward underestimations, thus increasing criticality rather than accuracy in assessments. We conclude that, by elevating normative expectations, psychological activation releases prodemocratic selection pressures in the evolution of regimes.

Cross-Cultural Variations in Extreme Rejecting and Extreme Affirming Response Styles
Cross-Cultural Variations in Extreme Rejecting and Extreme Affirming Response Styles. Tieyuan Guo, Roy Spina. Journal of Cross-Cultural Psychology, September 9, 2019. https://doi.org/10.1177/0022022119873072
Abstract: Previous research has discussed cultural differences in moderacy vs extremity response styles. The present research found that cultural differences in response styles were more complex than previously speculated. We investigated cross-cultural variations in extreme rejecting versus affirming response biases. Although research has indicated that overall Chinese have less extreme responses than Westerners, the difference may be mainly driven by extreme rejecting responses because respondents consider answering survey questions as a way of interacting with researchers, and extreme rejecting responses may disrupt harmony in relationships, which is valued more in Chinese collectivistic culture than in Western individualistic cultures. Studies 1 and 2 revealed that Chinese had less extreme rejecting response style than did British, whereas they did not differ in extreme affirming response style. Study 2 further revealed that the cross-cultural asymmetry in extreme rejecting versus affirming response styles was partially accounted for by individualism orientation at the individual level. Consistently, Study 3 revealed that at the country level, individualism was positively associated with extreme rejecting response style, but was not associated with extreme affirming response style, suggesting that individualism accounted for the asymmetric cultural variation in extreme rejecting versus affirming response styles.

From 1972... Erving Goffman's Relations in Public: Microstudies of the Public Order
Relations in Public: Microstudies of the Public Order. Erving Goffman. Penguin, 1972. ISBN-13 978-0140216141
Editor text:
Excerpt:
Editor text:
Until recently, to be in a "public place" meant to feel safe. That has changed, especially in cities. Urban dwellers sense the need to quickly react to gestural cues from persons in their immediate presence in order to establish their relationship to each other. Through this communication they hope to detect potential danger before it is too late for self-defense or flight. The ability to read accurately the "informing signs" by which strangers indicate their relationship to one another in public or semi-public places without speaking, has become as important as understanding the official written and spoken language of the country.
In Relations in Public, Erving Goff man provides a grammar of the unspoken language used in public places. He shows that the way strangers relate in public is part of a design by which friends and acquaintances manage their relationship in the presence of bystanders. He argues that, taken together, this forms part of a new domain of inquiry into the rules for co-mingling, or public order.
Most people give little thought to how elaborate and complex our everyday behavior in public actually is. For example, we adhere to the rules of pedestrian traffic on a busy thoroughfare, accept the usual ways of acting in a crowded elevator or subway car, grasp the delicate nuances of conversational behavior, and respond to the rich vocabulary of body gestures. We behave differently at weddings, at meals, in crowds, in couples, and when alone. Such everyday behavior, though generally below the level of awareness, embodies unspoken codes of social understandings necessary for the orderly conduct of society.
Excerpt:
p 32: "All of this may be seen in miniature in elevator behavior. Passengers have two problems: to allocate the space equably, and to maintain a defensible position, which in this context means orientation to the door and center with the back up against the wall if possible. The first few individuals can enter without anyone present having to rearrange himself, but very shortly each new entrant – up to a certain number – causes all those present to shift position and reorient themselves in sequence. Leave-taking introduces a tendency to reverse the cycle, but this is tempered by the countervailing resistance to appearing uncomfortable in an established distance from another. Thus, as the car empties, passengers acquire a measure of uneasiness, caught between two opposing inclinations – to obtain maximum distance from others and to inhibit avoidance behavior that might give offense."
p 31: "(when the two are of opposite sex, there exists the added complication that failure to move away when possible can be taken as a sign of undue interest.)"

3G Internet reduces government approval and increases the perception of corruption in government when the internet is not censored; effect is stronger when traditional media is censored
Guriev, Sergei and Melnikov, Nikita and Zhuravskaya, Ekaterina, 3G Internet and Confidence in Government (June 30, 2019). SSRN: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3456747
Abstract: How does the internet affect government approval? Using surveys of 840,537 individuals from 2,232 subnational regions in 116 countries in 2008-2017 from the Gallup World Poll and the global expansion of 3G networks, we show that an increase in internet access reduces government approval and increases the perception of corruption in government. This effect is present only when the internet is not censored and is stronger when traditional media is censored. Actual incidents of corruption translate into higher corruption perception only in places covered by 3G. In Europe, the expansion of mobile internet increased vote shares of anti-establishment populist parties.

Binge drinking as a costly sexual signal (the drinker is capable of bearing the harmful consequences of alcohol consumption): Having more eligible men in a district compared to women was associated with higher male drinking rates
Operational Sex Ratio Predicts Binge Drinking Across U.S. Counties. Toe Aung et al. Evolutionary Psychology, September 29, 2019. https://doi.org/10.1177/1474704919874680
Abstract: Previous research suggests that binge drinking among young men serves as a “costly signal” to potential mates, such that the binge drinker is capable of bearing the harmful consequences of alcohol consumption. Here, we propose that binge drinking among young adults is conditionally dependent upon the signaler’s willingness to take risks, which is influenced by the local operational sex ratio (OSR). Using archived binge drinking estimates from 2009 to 2012 and Census Bureau records of OSRs, we tested the relationship between OSR and binge drinking rates at the county level across 3,143 U.S. counties against hypotheses drawn from evolutionary theory. Results from our mixed-effects models revealed that a higher overall OSR (i.e., more eligible men compared to women) was associated with higher male binge drinking rates but lower female binge drinking rates. A higher OSR particularly in the 20–29 and 50+ age groups predicted higher male binge drinking rates but lower female binge drinking rates. Our findings generally support predictions derived from evolutionary theory and suggest that binge drinking may function as a costly sexual signal, conditionally regulated by age and the local sex ratio.

Rebellious music genres (rap, punk & heavy metal) are not linked to maladaptive personality traits; conservative music (country, gospel) was weakly linked to neurotic, hostile, & eccentric tendencies
Maladaptive personality and psychopathy dimensions as predictors of music and movie preferences in US adults. Pavel S Blagov et al. Psychology of Music, August 13, 2019. https://doi.org/10.1177/0305735619864630
Abstract: We link modern conceptualizations of maladaptive personality and psychopathy dimensions to music and movie genre preferences. Participants, N = 379, completed the Personality Inventory (5th ed.; PID-5), Triarchic Psychopathy Measure (TriPM), and music and movie preferences questionnaires. The structure of some, but not all, music preferences factors aligned with previous reports. Overall, maladaptive traits had meaningful, albeit modest links to entertainment media preferences, but not to the kinds of intense or rebellious music genres sometimes labeled as “problem” entertainment in prior literature. Support emerged for several a priori hypotheses, but some predictions based on the three- and five-factor normal personality trait and entertainment preferences literature did not generalize to a five-factor formulation of maladaptive personality. We discuss the findings’ implications and several likely sources of inconsistencies in the literature on music and movie preferences and personality.

Alcohol by night: People were motivated to preload to save money & socialise, were likely to drink more than they predicted, & were more surprised by their alcohol reading the more they drank
Drinking to go out or going out to drink? A longitudinal study of alcohol in night-time entertainment districts. Grant J. Devilly et al. Drug and Alcohol Dependence, September 29 2019, 107603. https://doi.org/10.1016/j.drugalcdep.2019.107603
Highlights
• End of night intoxication is predicted by beginning of night intoxication.
• Personality and demographics differentially predict drinking for males and females.
• People drink more than they anticipate within night time entertainment districts.
• Drinkers are surprised by the degree of their intoxication the more they drink.
Abstract
Background: Recent research has highlighted the growing trend of alcohol preloading before a night out. We wished to look at people’s motivations for preloading, their estimation for drinking during the night, and assess the impact that preloading has on how inebriated people become across the night as measured by Breath Approximated blood Alcohol Content (BrAC).
Method: We randomly surveyed and breath-tested patrons as they entered and exited Night Time Entertainment Districts (NEDs) in Brisbane, Queensland. We obtained 360 participants who were encouraged to contact us at the end of their night, compensating them for their time with a taxi voucher. Of these, 143 people returned and completed an exit questionnaire.
Findings: We found that people were motivated to preload in order to save money and socialise, were likely to drink more than they predicted over the course of the night, and were more surprised by their alcohol reading the higher their BrAC; this trajectory displayed little difference between men and women. It was further found that, for men, personality contributed 19% of the variance to exit BrAC, but entry BrAC accounted for nearly 38% of unique variance. For women, body mass index significantly predicted exit BrAC (9% unique variance), but entry BrAC accounted for nearly 30% unique variance.
Interpretation: To reduce general levels of intoxication in city NEDs, interventions should focus on having people come in earlier, less drunk, and be taught to have more realistic appraisals of their drinking.

The roots of intolerance and opposition to compromise: The effects of absolutism on political attitudes
The roots of intolerance and opposition to compromise: The effects of absolutism on political attitudes. Kevin Arceneaux. Personality and Individual Differences, Volume 151, December 1 2019, 109498. https://doi.org/10.1016/j.paid.2019.07.008
Abstract: Compromise and tolerance are often considered to be virtues, especially in the realm of democratic politics. Without them, it would be difficult for democratic institutions to fulfill their intended purpose: resolving disputes peacefully. Yet many controversial political issues reduce to moral imperatives that engender strong, uncompromising opinions. There is a tendency to conceptualize moralizing as an aspect of issues, but considerable evidence suggests that the tendency to think about the world in absolutist terms is also a psychological predisposition. In this project, I seek to elaborate the correlates and consequences of individual differences in absolutism. A suite of observational analyses and an experimental test conforms that there is a great deal of variance in ethical predispositions across individuals and that these differences matter politically. Absolutists are more likely to adopt extreme opinions, display intolerance toward political disagreement, and punish politicians who make compromises.

James Hankins' Virtue Politics: Soulcraft and Statecraft in Renaissance Italy
Virtue Politics: Soulcraft and Statecraft in Renaissance Italy. James Hankins. Belknap Press: An Imprint of Harvard University Press, Dec 2019.
https://www.amazon.com/Virtue-Politics-Soulcraft-Statecraft-Renaissance/dp/0674237552
Convulsed by a civilizational crisis, the great thinkers of the Renaissance set out to reconceive the nature of society. Everywhere they saw problems. Corrupt and reckless tyrants sowing discord and ruling through fear; elites who prized wealth and status over the common good; military leaders waging endless wars. Their solution was at once simple and radical. “Men, not walls, make a city,” as Thucydides so memorably said. They would rebuild their city, and their civilization, by transforming the moral character of its citizens. Soulcraft, they believed, was a precondition of successful statecraft.
A dazzlingly ambitious reappraisal of Renaissance political thought by one of our generation’s foremost intellectual historians, Virtue Politics challenges the traditional narrative that looks to the Renaissance as the seedbed of modern republicanism and sees Machiavelli as its exemplary thinker. James Hankins reveals that what most concerned the humanists was not reforming laws or institutions so much as shaping citizens. If character mattered more than constitutions, it would have to be nurtured through a new program of education they called the studia humanitatis: the humanities.
We owe liberal arts education and much else besides to the bold experiment of these passionate and principled thinkers. The questions they asked―Should a good man serve a corrupt regime? What virtues are necessary in a leader? What is the source of political legitimacy? Is wealth concentration detrimental to social cohesion? Should citizens be expected to fight for their country?―would have a profound impact on later debates about good government and seem as vital today as they did then.
Tyler Cowen excerpts (Sep 29 2019, https://marginalrevolution.com/marginalrevolution/2019/09/virtue-politics.html):
I have sought to present the political ideas of the humanists as the expression of a movement of thought and action, similar in its physiognomy if not in its content to the movement of the philosophes of the Enlightenment. It was a movement that was stimulated by a crisis of legitimacy in late medieval Italy and by widespread disgust with its political and religious leadership. Its adherents were men who had wide experience -- often bitter, personal experience -- with tyranny. They knew that oligarchs and even popular governments could be as tyrannical as princes. Their movement was largely in agreement about its goals: to rebuild Europe's depleted reserves of good character, true piety, and practical wisdom. They also agreed widely about means: the revival of classical antiquity, which the humanists presented as an inspiring pageant, rich in examples of noble conduct, eloquent speech, selfless dedication to country, and inner moral strength, nourished by philosophy and uncorrupt Christianity. The humanist movement yearned after greatness, moral and political. Its most pressing historical questions were how ancient Rome had achieved her vast and enduring empire, and whether it was possible to bring that greatness to life again under modern conditions. This led to the question of whether it was the Roman Republic or the Principate that should be emulated; and, once the humanists had learned Greek, it provoked the further question of whether Rome was the only possible ancient model to emulate, or whether Athens or Sparta, or even the Persia of Xenophon's Cyrus, held lessons for contemporary statesmen.

This led to the question of whether it was the Roman Republic or the Principate that should be emulated; and, once the humanists had learned Greek, it provoked the further question of whether Rome was the only possible ancient model to emulate, or whether Athens or Sparta, or even the Persia of Xenophon's Cyrus, held lessons for contemporary statesmen.

From 2018... The Persistence of Established Dating Theories in a Real-Life Dyadic Blind Date Study. Yannick Nout, MSci Thesis, Applied Cognitive Psychology. Leiden Uni, Aug 2018. https://openaccess.leidenuniv.nl/bitstream/handle/1887/71521/Nout%2C%20Yannick-s1507869-MA%20Thesis%20ACP-2018.pdf
Abstract: Mating is fundamental for reproduction and family life and the drive to mate stands high on the hierarchy of human needs. Consequently, there are many theories and concepts regarding dating. However, studies done on this topic are usually conducted in a laboratory setting, while dating normally occurs in much less controlled conditions. This study aimed to test if several established dating theories (partner preferences, Attractiveness Halo Effect, (nonverbal) communication and expressions, mimicry and physiological synchrony) hold up in a more realistic real-life dating experiment. This study was conducted at public events and combined questionnaires, behavioural expressions and physiological measures (eye tracking, heart rate, skin conductance). Participants (N = 140) were formed into opposite-sex dyads and interacted three times during their ‘date’ (first impression, verbal and nonverbal interaction). Many of our findings were in line with previous research. Partner preferences seem to be in line with research; the Attractiveness Halo Effect occurred; participants were not accurate in guessing if they were liked by their partner; submissive behaviour reflected liking, sexual attraction and attraction to some degree, however results regarding affiliative behaviour contradicted previous research; only female sexual attraction is affected by submissive and affiliative behaviour; there is evidence that mimicry occurs; physiological synchrony affected females’ opinions, male date outcome and date outcome match. These results suggest that most dating theories and concepts to a certain degree hold up in real-life contexts.

Alan Blinder's influential estimate, 2007: 25pct more of U.S. jobs were at risk of being offshored; instead, more jobs were added than lost, against the scaremongering that millions would be lost
Report: Overboard on Offshore Fears. Adam Ozimek, chief economist at Upwork. Sep 27 2019. https://www.upwork.com/press/economics/report-overboard-on-offshore-fears/
In 2007 an economist predicted U.S. service sector jobs were at high risk of being offshored. Data now shows that instead they are going remote.
Executive Summary
Advancing technology is unlocking great potential in remote work opportunities by making it increasingly easy for work that used to be done in person to now be done remotely. Yet these changes have led some researchers to worry about the offshoring of U.S. jobs. In one influential estimate from 2007, economist Alan Blinder projected that a quarter or more of U.S. jobs were at risk of being offshored.
In this report, we take a look at the data from the decade-plus since this warning was issued and find that the techno-pessimism was misplaced. Instead of being offshored, the types of work predicted to be at risk of offshoring are increasingly being performed remotely by workers within the U.S. While technology may be giving firms the choice of hiring workers from around the globe, this is not translating to job loss. Instead, it’s leading to more U.S. workers enjoying the greater freedom, flexibility, and shorter commutes of remote work.
This analysis investigates the growth of remote work in the U.S. using Census Bureau data, unique surveys and data from Upwork, the largest online work website. The key results are as follows:
. Contrary to popular predictions made in 2007, offshoring risk is not related to job loss for hundreds of occupations.
. Instead, those jobs predicted as “at risk” of being offshored are significantly more remote work based today.
. Data from Upwork shows that U.S. knowledge workers retain a competitive advantage even in a global marketplace, and are in demand from both U.S. businesses and businesses around the world.
. Young business owners and hiring managers are more comfortable with remote work, and younger workers are more likely to want to work remotely, which suggests the remote work trend will continue to grow based on demographic change alone.
. Instead of focusing on how demand might shift overseas, research should consider how remote work could help shift demand within the U.S. to lower cost of living areas that are currently lacking in economic opportunity.

The White-Collar Job Apocalypse That Didn’t Happen. Ben Casselman. TNYT, Sep 27 2019. https://www.nytimes.com/2019/09/27/business/economy/jobs-offshoring.html
In a follow-up paper released Friday, another economist, Adam Ozimek, revisited Mr. Blinder’s analysis to see what had happened over the past decade. Some job categories that Mr. Blinder identified as vulnerable [to offshoring], like data-entry workers, have seen a decline in United States employment. But the ranks of others, like actuaries, have continued to grow.
Over all, of the 26 occupations that Mr. Blinder identified as “highly offshorable” and for which Mr. Ozimek had data, 15 have added jobs over the past decade and 11 have cut them. Altogether, those occupations have eliminated fewer than 200,000 jobs over 10 years, hardly the millions that many feared. A second tier of jobs — which Mr. Blinder labeled “offshorable” — has actually added more than 1.5 million jobs.
But Mr. Blinder didn’t miss the mark entirely, said Mr. Ozimek, who is chief economist at Upwork, an online platform for hiring freelancers. The new study found that in the jobs that Mr. Blinder identified as easily offshored, a growing share of workers were now working from home. Mr. Ozimek said he suspected that many more were working in satellite offices or for outside contractors, rather than at a company’s main location. In other words, technology like cloud computing and videoconferencing has enabled these jobs to be done remotely, just not quite as remotely as Mr. Blinder and many others assumed.

Logic, Fast and Slow: The Persistent Difficulty of the Monty Hall Problem
Logic, Fast and Slow: The Persistent Difficulty of the Monty Hall Problem. Jay Kosegarten & Gary Kose. EvoS Journal, 2019, NEEPS XII, pp. 24-42. http://evostudies.org/wp-content/uploads/2019/07/Kosegarten-Kose_Vol10SpIss1.pdf
ABSTRACT: Evolutionary cognitive psychology is equipped to answer questions regarding not only human reasoning but also its limitations. Given that the field argues for naturally selected reasoning capacities (either broad or modular), the causes of certain cognitive errors and biases are of important interest. Kahneman (2011) has investigated and explicated the many fallacies in human logic that can lead people to make less than optimal judgments and decisions. Evolutionary cognitive psychologists have examined both probability judgments and conditional reasoning. Taken together, it would appear that evolutionary psychology could shed light on the notion that humans think both ‘fast and slow.’ This study examined two aspects of logical problem-solving hypothesized to be necessary for deducing the optimal response to the Monty Hall problem. The authors investigated the effects of a demonstration designed to emphasize the logic of the Monty Hall problem and to facilitate perspective-change, and the authors investigated the effects of counterfactual reasoning tasks. Alone, these two conditions—the demonstration and counterfactual reasoning—did not improve performance over controls. When combined, they did significantly improve subjects’ performance. We argue that subjects’ strong tendency to respond illogically to the Monty Hall problem is an example of fast, System 1 thinking and that the combined cognitive influences of a logical demonstration and counterfactual reasoning facilitated slow, System 2 thinking. Further we argue that slow, System 2 thinking operates with two subsystems called ‘fast logic’ and ‘slow logic.’

Italy: 75% of immigrants integrate into the majoritarian culture over a generation; interestingly, a lower cultural intolerance of Italians towards minorities would lead to slower cultural integration
Marriage, Fertility, and Cultural Integration in Italy. Alberto Bisin, Giulia Tura. NBER Working Paper No. 26303, September 2019. https://www.nber.org/papers/w26303
We study the cultural integration of immigrants, estimating a structural model of marital matching along ethnic dimensions, exploring in detail the role of fertility, and possibly divorce in the integration process. We exploit rich administrative demographic data on the universe of marriages formed in Italy, as well as birth and separation records from 1995 to 2012. We estimate strong preferences of ethnic minorities' towards socialization of children to their own identity, identifying marital selection and fertility choices as fundamental socialization mechanisms. The estimated cultural intolerance of Italians towards immigrant minorities is also substantial. Turning to long-run simulations, we find that cultural intolerances, as well as fertility and homogamy rates, slow-down the cultural integration of some immigrant ethnic minorities, especially Latin America, East Asia and Sub-Saharan Africa. Nonetheless, 75% of immigrants integrate into the majoritarian culture over the period of a generation. Interestingly, we show by counterfactual analysis that a lower cultural intolerance of Italians towards minorities would lead to slower cultural integration by allowing immigrants a more widespread use of their own language rather than Italian in heterogamous marriages. Finally, we quantitatively assess the effects of large future immigration inflows.

Women & men perception of breasts: The bigger, the higher the reproductive efficiency, lactational efficiency, sexual desire, promiscuity attributed; & perceived as less faithful & less intelligent
Stereotypical and Actual Associations of Breast Size with Mating-Relevant Traits. Krzysztof Kościński, Rafał Makarewicz, Zbigniew Bartoszewicz. Archives of Sexual Behavior, September 27 2019. https://link.springer.com/article/10.1007/s10508-019-1464-z
Abstract: Breast size varies substantially among women and influences perception of the woman by other people with regard to her attractiveness and other characteristics that are important in social contexts, including mating. The theory of sexual selection predicts that physical criteria of partner selection should be markers of the candidate’s desirable properties, mainly biological quality. Few studies, however, have examined whether breast size really signals biological quality or its components and whether observers accurately interpret these signals. Our first study encompassed 163 young women and aimed to establish actual correlates of breast size. The aim of the second study was to determine preferences and stereotypes related to breast size: 252–265 women and men evaluated female digital figures varying in, among other characteristics, breast size. Breast size (breast circumference minus chest circumference) was negatively associated with body asymmetry and positively associated with infections of the respiratory system, but did not correlate with infections of the digestive system, openness to casual sex, and testosterone and estradiol level. Women and men perceived breasts in a similar way to each other: the bigger the breasts the higher the reproductive efficiency, lactational efficiency, sexual desire, and promiscuity attributed to the woman. Nevertheless, large breasts were not regarded more attractive than average ones, though small breasts were the least attractive. In addition, big-breasted women were perceived as less faithful and less intelligent than women with average or small breasts. We discuss our results from the perspectives of evolutionary psychology, perceptual biases, and social stereotypes.
