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.

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:

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.

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.

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.

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:

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.

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.

A mindset of optimism is associated with lower cardiovascular risk and that promotion of optimism and reduction in pessimism may be important for preventive health

Association of Optimism With Cardiovascular Events and All-Cause Mortality - A Systematic Review and Meta-analysis. Alan Rozanski et al. JAMA Netw Open. 2019;2(9):e1912200. September 27, 2019. doi:10.1001/jamanetworkopen.2019.12200


Key Points
Question  Is a mindset of optimism associated with a lower risk of cardiovascular events and all-cause mortality?

Findings  In this meta-analysis of 15 studies including 229 391 individuals, optimism was associated with a lower risk of cardiovascular events and pessimism was associated with a higher risk of cardiovascular events; the pooled association was similar to that of other well-established cardiac risk factors.

Meaning  The findings suggest that a mindset of optimism is associated with lower cardiovascular risk and that promotion of optimism and reduction in pessimism may be important for preventive health.

Abstract
Importance  Optimism and pessimism can be easily measured and are potentially modifiable mindsets that may be associated with cardiovascular risk and all-cause mortality.

Objective  To conduct a meta-analysis and systematic review of the association between optimism and risk for future cardiovascular events and all-cause mortality.

Data Sources and Study Selection  PubMed, Scopus, and PsycINFO electronic databases were systematically searched from inception through July 2, 2019, to identify all cohort studies investigating the association between optimism and pessimism and cardiovascular events and/or all-cause mortality by using the following Medical Subject Heading terms: optimism, optimistic explanatory style, pessimism, outcomes, endpoint, mortality, death, cardiovascular events, stroke, coronary artery disease, coronary heart disease, ischemic heart disease, and cardiovascular disease.

Data Extraction and Synthesis  Data were screened and extracted independently by 2 investigators (A.R. and C.B.). Adjusted effect estimates were used, and pooled analysis was performed using the Hartung-Knapp-Sidik-Jonkman random-effects model. Sensitivity and subgroup analyses were performed to assess the robustness of the findings. The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline was followed.

Main Outcomes and Measures  Cardiovascular events included a composite of fatal cardiovascular mortality, nonfatal myocardial infarction, stroke, and/or new-onset angina. All-cause mortality was assessed as a separate outcome.

Results  The search yielded 15 studies comprising 229 391 participants of which 10 studies reported data on cardiovascular events and 9 studies reported data on all-cause mortality. The mean follow-up period was 13.8 years (range, 2-40 years). On pooled analysis, optimism was significantly associated with a decreased risk of cardiovascular events (relative risk, 0.65; 95% CI, 0.51-0.78; P < .001), with high heterogeneity in the analysis (I2 = 87.4%). Similarly, optimism was significantly associated with a lower risk of all-cause mortality (relative risk, 0.86; 95% CI, 0.80-0.92; P < .001), with moderate heterogeneity (I2 = 73.2%). Subgroup analyses by methods for assessment, follow-up duration, sex, and adjustment for depression and other potential confounders yielded similar results.

Conclusions and Relevance  The findings suggest that optimism is associated with a lower risk of cardiovascular events and all-cause mortality. Future studies should seek to better define the biobehavioral mechanisms underlying this association and evaluate the potential benefit of interventions designed to promote optimism or reduce pessimism.


Introduction

Extensive evidence has demonstrated an association between negative emotions, social factors, and certain chronic stress conditions and adverse cardiac outcomes.1 Less well studied has been the potential association between positive and negative mindsets and cardiac risk. Such research is of interest because mind-sets are potentially modifiable, thus making them a novel relevant target for clinical intervention. One such mindset is an individual’s level of optimism, commonly defined as the tendency to think that good things will happen in the future.2 Empirical studies have long indicated that more optimistic individuals are more likely to succeed at work and in school, sports, politics, relationships, and other forms of life endeavors.3,4 A more recent study also reported positive associations between optimism and a range of favorable physical health outcomes.5 Nevertheless, the assessment of optimism and pessimism in cardiac medical practice is uncommon. In 2001, Kubzansky and colleagues6 reported the first study, to our knowledge, to find an association between higher optimism and a lower risk for specific cardiac outcomes, including angina, myocardial infarction, and cardiac death. They showed effects of optimism beyond those of depression or other forms of psychological distress, a critical finding because a concern about such findings is that they simply reflect the absence of depression rather than active effects of optimism. Since then, similar findings have been described in other studies,7-20 and most studies considered depression or distress as a potential confounder. To consider these findings more systematically, we conducted a meta-analysis of studies that have assessed the association between optimism and pessimism and adverse cardiac outcomes. Our goals were to evaluate the magnitude of this association, the consistency of results among reported studies, the influence of potential confounders, and the quality of the reported literature.

Vegetarian diets may be perceived as inadequately nutritious, inadequately tasty, socially stigmatizing, too expensive, unfamiliar, inconvenient; dominant factors are the two first

Taste and health concerns trump anticipated stigma as barriers to vegetarianism. Daniel L.Rosenfeld, A. JanetTomiyama. Appetite, Volume 144, January 1 2020, 104469. https://doi.org/10.1016/j.appet.2019.104469

Abstract: Meat-eaters report that a number of barriers inhibit them from going vegetarian—for example, perceiving vegetarian diets to be inadequately nutritious, too expensive, unfamiliar, inconvenient, inadequately tasty, and socially stigmatizing. However, research identifying which barriers uniquely predict meat-eaters’ openness to going vegetarian is lacking from the current literature. In the present research, accordingly, we conducted a highly powered, preregistered study (N = 579) to identify which barriers uniquely predict openness to going vegetarian. We focused specifically on anticipated vegetarian stigma, given recent qualitative evidence highlighting this attitude as an influential barrier. That is, do meat-eaters resist going vegetarian because they fear that following a vegetarian diet would make them feel stigmatized? Being of younger age, more politically conservative, White, and residing in a rural community predicted greater anticipated vegetarian stigma among meat-eaters. Frequentist and Bayesian analyses converged, however, to suggest that anticipated vegetarian stigma was not a significant predictor of openness to going vegetarian. The strongest predictors of openness were perceived tastiness and perceived healthfulness of vegetarian dieting. These factors—but not anticipated stigma—furthermore explained why men (compared to women) and political conservatives (compared to liberals) were particularly resistant to going vegetarian.

Bullshitting frequency was positively associated with overclaiming and negatively associated with sincere self-presentation, honesty, cognitive ability, open-minded cognition, & self-regard

Littrell, Shane, Evan Risko, and Jonathan A. Fugelsang. 2019. “The Bullshitting Frequency Scale: Development and Psychometric Properties.” PsyArXiv. September 27. doi:10.31234/osf.io/dxzqh

Abstract: Recent psychological research has identified important individual differences associated with receptivity to bullshit which has greatly enhanced our understanding of the processes behind susceptibility to pseudo-profound or otherwise misleading information. However, the bulk of this research attention has focused on cognitive and dispositional factors related to bullshit (the product), while largely overlooking the influences behind bullshitting (the act), leaving several important theoretical questions thus far unanswered. Here, we present results from three studies focusing on the construction and validation of a new, reliable scale measuring the frequency with which individuals engage in bullshitting in everyday situations. Overall, bullshitting frequency was positively associated with overclaiming and negatively associated with sincere self-presentation, honesty, cognitive ability, open-minded cognition, and self-regard. These results represent an important step forward by demonstrating the utility of the Bullshitting Frequency Scale as well as highlighting certain individual differences that may play important roles in the extent to which individuals engage in everyday bullshitting.

Introduction

“One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share.” – Harry Frankfurt (1986)

Given the increasing prevalence of misleading information and “fake news” on the internet and society at large (Lewandosky, Ecker, & Cook, 2017), a growing body of work has emerged that focuses on better understanding the nature of bullshit and bullshitting. Some has been more descriptive, highlighting the use of bullshit in politics (Kristansen & Kaussler, 2018), business organizations (Martin & Wilson, 2011; Spicer, 2013), academic settings (Cohen, 2012), and everyday life (Frankfurt, 1986). Other research, in psychology, has taken a more empirical approach, examining individual differences associated with receptivity to bullshit and the production of bullshit (i.e., bullshitting). For instance, multiple studies have linked bullshit receptivity (i.e., the propensity to rate vacuous, randomly-generated statements as profound) to factors such as decreased engagement in analytic thinking (Pennycook, Cheyene, Barr, Koehler, & Fugelsang, 2015) and biased pattern perception (Walker, Turpin, Stolz, Fugelsang, & Koehler, 2019). Other work has examined the functions of bullshit production (i.e., bullshitting) as a strategy for managing impressions and attitude change in areas from simple social interactions to assessments of abstract art (Petrocelli, 2018; Turpin et al., 2019).


Bullshitting, broadly defined

Philosopher Harry Frankfurt (1986) is perhaps best known for his seminal piece, On Bullshit, in which he described a “bullshitter” as a person who deliberately conveys a false/phony impression of himself or his intentions in a way that is unconcerned with the truth. In other words, the veracity of what the bullshitter is saying does not matter, as his or her primary concern is whether others are persuaded by it. Frankfurt contrasts this from lying in that the liar is deliberately attempting to get others to believe a falsehood. A key distinction is in the motivation; a liar’s goal is to deceive whereas a bullshitter’s goal is often to impress.

Though this explication of bullshitting is generally well-regarded, some have critiqued it as capturing “just one flower in the lush garden of bullshit” (Cohen, 2012). Indeed, several have modified or expanded on his definitions to provide a more comprehensive view of bullshitting in daily life. For instance, Cohen (2012) highlighted that the aim of some bullshitters is to impress using discourse constructed with “unclarifiable unclarity”; that is, relying on vacuous, confusing buzzwords which obscure the fact that the statements, while superficially impressive, contain no discernible meaning. An example cited is the arguably impenetrable, jargon-heavy writing found in some academic publications. For Cohen, this type of bullshit is distinct from Frankfurtian bullshit in that the Cohen-bullshitter is unconcerned with the lucidity of what he says, rather than unconcerned with its truth-value (Cohen, 2012).

Another proposed type of bullshit/bullshitting is evasive bullshitting, which involves speech aimed at avoiding answering questions one does not want to answer, as giving direct answers may be harmful to oneself or others (Carson, 2016). For instance, a politician may be motivated to use evasive bullshitting when questioned by a member of the press if, for instance, a direct answer could potentially cost votes (harm to self) or jeopardize national security (harm to others). An equally common example might be one’s romantic partner asking if their new haircut or outfit makes them look unattractive. In some cases, a frank response might result in undesirable social costs for either party (or both).

Finally, some have attempted to refine Frankfurt’s assertion that bullshitting, by definition, is unconnected to a concern for the truth (Frankfurt, 1986, p. 90). For instance, Stokke and Fallis (2017) characterize bullshitting as speech that is unconcerned with the truthful advancement of an honest discourse, rather than unconcerned with the veracity of individual statements. Put another way, the bullshitter is not indifferent toward the truth-value of the content of each thing he says. Rather, he is indifferent toward whether his statements create an impression that the overall discourse leads to an honest representation of the truth. Meibauer (2018) describes bullshitting as having a “misrepresentational intent” that is based on “a loose concern for the truth” (p. 366). That is, the bullshitter may not know the truth-value of his statements, yet he is often aware of his unawareness, and asserts himself with a sense of certainty that his statements are true regardless. Indeed, the bullshitter’s goal is not to communicate an objective truth, but to instill a particular belief or impression in another person – regardless of whether the bullshitter also believes it – and can be accomplished through misleading exaggeration or implicature (Stokke & Fallis, 2017; Webber, 2013).

Claims for mirror self-recognition have been made for numerous species ranging from dolphins and elephants to fish and ants; reproducible experimental evidence is avaialable only for some great apes

Abstract: Claims for mirror self-recognition have been made for numerous species ranging from dolphins and elephants to fish and ants. But based on rigorous, reproducible experimental evidence only some great apes and humans have shown clear, consistent and convincing evidence that they are capable of correctly deciphering mirrored information about themselves. In this article we critique some of the recent claims for self-recognition in other species and summarize some of the cognitive implications of the capacity to become the object of your own attention. Recent neurobiological evidence now appears to validate the connection between self-recognition and self-awareness.

From 2015... Male homosexual preference: Available data challenges the common view of MHP being a “virtually universal” trait; social stratification together with hypergyny seem necessary for its evolution

From 2015... Barthes J, Crochet P-A, Raymond M (2015) Male Homosexual Preference: Where, When, Why? PLoS ONE 10(8), Aug 12 2016, e0134817. https://doi.org/10.1371/journal.pone.0134817

Abstract: Male homosexual preference (MHP) has long been of interest to scholars studying the evolution of human sexuality. Indeed, MHP is partially heritable, induces a reproductive cost and is common. MHP has thus been considered a Darwinian paradox. Several questions arise when MHP is considered in an evolutionary context. At what point did MHP appear in the human evolutionary history? Is MHP present in all human groups? How has MHP evolved, given that MHP is a reproductively costly trait? These questions were addressed here, using data from the anthropological and archaeological literature. Our detailed analysis of the available data challenges the common view of MHP being a “virtually universal” trait present in humans since prehistory. The conditions under which it is possible to affirm that MHP was present in past societies are discussed. Furthermore, using anthropological reports, the presence or absence of MHP was documented for 107 societies, allowing us to conclude that evidence of the absence of MHP is available for some societies. A recent evolutionary hypothesis has argued that social stratification together with hypergyny (the hypergyny hypothesis) are necessary conditions for the evolution of MHP. Here, the link between the level of stratification and the probability of observing MHP was tested using an unprecedented large dataset. Furthermore, the test was performed for the first time by controlling for the phylogenetic non-independence between societies. A positive relationship was observed between the level of social stratification and the probability of observing MHP, supporting the hypergyny hypothesis.

From 2016... Homophobia might reflect concerns about sexuality in general and not homosexuality in particular

From 2016... Homophobia Is Related to a Low Interest in Sexuality in General: An Analysis of Pupillometric Evoked Responses. Boris Cheval et al. The Journal of Sexual Medicine, Volume 13, Issue 10, October 2016, Pages 1539-1545. https://doi.org/10.1016/j.jsxm.2016.07.013

Abstract

Introduction: A recent study by Cheval et al (J Sex Med 2016;13:825–834) found that individuals high in homophobia look significantly less long at sex-related photographs, regardless of their nature (ie, homosexual or heterosexual). Because viewing time is under some conscious control, this result could indicate that individuals high in homophobia have a low sexual interest in any sexual stimuli or are consciously motivated to avoid sexual material in line with their conscious values.

Aim: To determine the mechanism underlying shorter viewing time of sex-related photographs in individuals high in homophobia using pupil dilatation, which is considered a spontaneous, unconscious, and uncontrollable index of sexual interest.

Methods: Heterosexual men (N = 36) completed a questionnaire assessing their level of homo-negativity and then performed a picture-viewing task with simultaneous eye-tracking recording to assess their pupillary responses to the presentation of sexually related or neutral photographs.

Main Outcome Measures: Non-linear mixed models were carried out to fit the individual non-linear trajectories of pupillary reaction. Different parameters were obtained including the final asymptote of the pupillary response.

Results: Results showed that the final pupil size of men high in homophobia increased significantly less to the presentation of sex-related images (ie, heterosexual and homosexual) than the pupil size of men low in homophobia. In contrast, no significant difference in the final pupil size reaction toward homosexual images (vs heterosexual images) emerged between men high and men low in homophobia.

Conclusion: Theoretically, these findings reinforce the necessity to consider that homophobia might reflect concerns about sexuality in general and not homosexuality in particular.

Moderate to strong evidence for the absence of an experimental effect: Belief in a controlling God did not increase after a threat compared to an affirmation of personal control (US & the Netherlands)

Hoogeveen, Suzanne, Eric-Jan Wagenmakers, Aaron Kay, and Michiel van Elk. 2019. “Compensatory Control and Belief in God: A Registered Replication Report Across Two Countries.” PsyArXiv. September 27. doi:10.31234/osf.io/vqu2x

Abstract: Compensatory Control Theory (CCT) suggests that religious belief systems provide an external source of control that can substitute a perceived lack of personal control. In a seminal paper, Kay et al. (2008) experimentally demonstrated that a threat to personal control increases endorsement of the existence of a controlling God. In the current registered report, we conducted a high-powered (N = 829) direct replication of this effect, using samples from the Netherlands and the United States. Our results show moderate to strong evidence for the absence of an experimental effect across both countries: belief in a controlling God did not increase after a threat compared to an affirmation of personal control. In a complementary preregistered analysis, an inverse relation between general feelings of personal control and belief in a controlling God was found in the US, but not in the Netherlands. We discuss potential reasons for the replication failure of the experimental effect and cultural mechanisms explaining the cross-country difference in the correlational effect. Together, our findings suggest that experimental manipulations of control may be ineffective in shifting belief in God, but that individual differences in the experience of control may be related to religious beliefs in a way that is consistent with CCT.

Religiosity Predicts Evidentiary Standards: Religious individuals exhibited a bias for believing religious claims relative to scientific claims, while nonreligious guys were consistent in their standards of evidence across domains

Religiosity Predicts Evidentiary Standards. Emilio J. C. Lobato et al. Social Psychological and Personality Science, September 9, 2019. https://doi.org/10.1177/1948550619869613

Abstract: Research shows that religious and nonreligious individuals have different standards of evidence for religious and scientific claims. Here, in a preregistered replication and extension of McPhetres and Zuckerman, participants read about an effect attributed to either a scientific or religious cause, then assessed how much evidence, in the form of successful replications, would be needed to confirm or to reject the causal claim. As previously observed, religious individuals exhibited a bias for believing religious claims relative to scientific claims, while nonreligious individuals were consistent in their standards of evidence across domains. In a novel extension examining standards of evidence with respect to failures of replication, we found that religious individuals were consistent across domains, whereas nonreligious individuals indicated a lower threshold for rejecting religious claims relative to scientific claims. These findings indicate asymmetries in the evaluation of claims based on the presence versus absence of supportive evidence.

Facebook is found as a useful tool to fulfil human needs, which predict continued Facebook use intentions of participants, and further, satisfaction with life

Who Needs Social Networking? An Empirical Enquiry into the Capability of Facebook to Meet Human Needs and Satisfaction with Life. David Houghton, Andrew Pressey, Doga Istanbulluoglu. Computers in Human Behavior, September 27 2019. https://doi.org/10.1016/j.chb.2019.09.029

Highlights:
•    Investigation into the fulfilment of human needs through Facebook use.
•    SEM to assess human needs, Facebook use and Satisfaction with Life.
•    Facebook fulfils needs, and continued use is associated with satisfaction with life.

Abstract: Social Network Sites (SNS) have been the topic of much scholarly and public debate for the most part of the 21st century. A number of studies have investigated the benefits and drawbacks to using SNS, with Facebook the largest example boasting billions of active monthly users. In recent months, media commentary has raised a number of concerning cases surrounding Facebook’s use of data, its connection with other organizations and its legitimacy, making a number of open public calls to abandon the platform. However, active users still number in the billions, raising the question, “does Facebook achieve something on a fundamental human and social level that users are willing to overlook the potential drawback to its use?” Using Maslow’s needs hierarchy, this study adopts a survey approach (n=316) and explores the capacity for Facebook to satisfy human needs. Findings identify Facebook as a useful tool to fulfil human needs, which predict continued Facebook use intentions of participants, and further, satisfaction with life. These findings offer a broad-based view of Facebook use and its resonance with key motivators of behavior, supporting both Maslow’s needs hierarchy and highlighting the importance of need fulfilment for continued service use and satisfaction with life.

Those who are off Facebook for one week reduce news consumption, are less likely to recognize politically-skewed news stories, report being less depressed and engage in healthier activities. These results are strongest for men. Our results further suggest that, after the restriction, Facebook’s value increases, consistent with information loss or that using Facebook may be addictive.

The Social Effects of Internet Deprivation: Can You Engage in Political Activity Without Internet Access? Very little, it seems

Can You Engage in Political Activity Without Internet Access? The Social Effects of Internet Deprivation. Ryan Shandler, Michael L Gross, Daphna Canetti. Political Studies Review, September 26, 2019. https://doi.org/10.1177/1478929919877600

Abstract: To what extent can you engage in political activity in the modern age without Internet access? The growing dependence on Internet access to fulfill basic civil functions is threatened by increasing personal and societal cyber vulnerability. In this article, we explore the extent to which citizens are able, or unable, to engage in specific political activities in the absence of Internet connectivity. To concretize the subject, we test how Internet deprivation affects the ability to realize three basic elements of political participation: political expression, civic association, and access to information. To measure this, we develop a new experimental methodology that tests people’s ability to complete tasks related to each function under simulated treatments of Internet access or deprivation. This empirical methodology offers a new framework through which to quantify the realization of social tasks under experimental conditions. Early results suggest that the absence of Internet access significantly reduces task completion for activities related to political expression and political association and conditionally reduces task completion for practices associated with freedom of information. Having substantiated this empirical framework, we encourage its application to additional forms of political activity.

When a woman is more attractive than her mate, men desire to mate poach, and if a woman is less attractive than her partner, men desire to mate copy

Moran, J. B., & Wade, T. J. (2019). Perceptions of a mismatched couple: The role of attractiveness on mate poaching and copying. Evolutionary Behavioral Sciences, Sep 2019. http://dx.doi.org/10.1037/ebs0000187

Abstract: This research investigated how a couple’s discrepancy in attractiveness influences men’s decision to mate poach or mate copy. The participants (N = 97 heterosexual men) were presented with 3 photos of a quasi couple in which the woman was consistent, and the 3 men were unattractive, equally, or more attractive than her. This study used ranking questions to assess heterosexual men’s perception of a couple. Participants were asked to drag and drop the 3 randomized photos in order of preference for 8 randomized questions regarding mate poaching and mate copying. Eight Friedman tests were conducted and revealed a significant difference between the rankings of the photos for each situation. These findings suggest that there are clear differences between the conditional mating strategies men use. Results revealed that when a woman is more attractive than her mate, men desire to mate poach, and if a woman is less attractive than her partner, men desire to mate copy.

The relationship between tickling, sensation, and laughter is complex; tickling or its mere anticipation makes us laugh, but not when we self-tickle; the study uses rats to understand self-tickle suppression & tickle anticipation

Behavioral and Cortical Correlates of Self-Suppression, Anticipation, and Ambivalence in Rat Tickling. Shimpei Ishiyama, Lena V. Kaufmann, Michael Brecht. Current Biology, September 26 2019. https://doi.org/10.1016/j.cub.2019.07.085

Highlights
•    Self-touch suppresses vocalizations and cortical excitation
•    Self-touch suppression is rescued by blocking cortical inhibition
•    Rats show ambivalent response to tickling
•    Layer 5 somatosensory cortex represents tickle anticipation

Summary: The relationship between tickling, sensation, and laughter is complex. Tickling or its mere anticipation makes us laugh, but not when we self-tickle. We previously showed rat somatosensory cortex drives tickling-evoked vocalizations and now investigated self-tickle suppression and tickle anticipation. We recorded somatosensory cortex activity while tickling and touching rats and while rats touched themselves. Allo-touch and tickling evoked somatotopic cortical excitation and vocalizations. Self-touch induced wide-ranging inhibition and vocalization suppression. Self-touch also suppressed vocalizations and cortical responses evoked by allo-touch or cortical microstimulation. We suggest a global-inhibition model of self-tickle suppression, which operates without the classically assumed self versus other distinction. Consistent with this inhibition hypothesis, blocking cortical inhibition with gabazine abolished self-tickle suppression. We studied anticipation in a nose-poke-for-tickling paradigm. Although rats nose poked for tickling, they also showed escaping, freezing, and alarm calls. Such ambivalence (“Nervenkitzel”) resembles tickle behaviors in children. We conclude that self-touch-induced GABAergic cortical inhibition prevents self-tickle, whereas anticipatory layer 5 activity drives anticipatory laughter.

Those who are off Facebook for one week reduce news consumption, are less likely to recognize politically-skewed news stories, report being less depressed and engage in healthier activities; these results are strongest for men

The economic effects of Facebook. Roberto Mosquera et al. Experimental Economics, September 26 2019. https://link.springer.com/article/10.1007/s10683-019-09625-y

Abstract: Social media permeates many aspects of our lives, including how we connect with others, where we get our news and how we spend our time. Yet, we know little about the economic effects for users. In 2017, we ran a large field experiment with over 1765 individuals to document the value of Facebook to users and its causal effect on news, well-being and daily activities. Participants reveal how much they value one week of Facebook usage and are then randomly assigned to a validated Facebook restriction or normal use. One week of Facebook is worth $67. Those who are off Facebook for one week reduce news consumption, are less likely to recognize politically-skewed news stories, report being less depressed and engage in healthier activities. These results are strongest for men. Our results further suggest that, after the restriction, Facebook’s value increases, consistent with information loss or that using Facebook may be addictive.
