Thinner than yourself: self-serving bias in body size estimation. Mara Mazzurega, Jlenia Marisa, Massimiliano Zampini, Francesco Pavani. Psychological Research, https://link.springer.com/article/10.1007/s00426-018-1119-z
Abstract: The self-serving bias is the tendency to consider oneself in unrealistically positive terms. This phenomenon has been documented for body attractiveness, but it remains unclear to what extent it can also emerge for own body size perception. In the present study, we examined this issue in healthy young adults (45 females and 40 males), using two body size estimation (BSE) measures and taking into account inter-individual differences in eating disorder risk. Participants observed pictures of avatars, built from whole body photos of themselves or an unknown other matched for gender. Avatars were parametrically distorted along the thinness–heaviness dimension, and individualised by adding the head of the self or the other. In the first BSE task, participants indicated in each trial whether the seen avatar was thinner or fatter than themselves (or the other). In the second BSE task, participants chose the best representative body size for self and other from a set of avatars. Greater underestimation for self than other body size emerged in both tasks, comparably for women and men. Thinner bodies were also judged as more attractive, in line with standard of beauty in modern western society. Notably, this self-serving bias in BSE was stronger in people with low eating disorder risk. In sum, positive attitudes towards the self can extend to body size estimation in young adults, making own body size closer to the ideal body. We propose that this bias could play an adaptive role in preserving a positive body image.

Much of theory in sociology consists of articles propounding theories that cannot be falsified, grounded in confirmation bias, crafted in a strange & inaccessible argot, appealing to pathos in the creation of a Moloch upon which to hang blame for the world’s ills
Avatars of the New Dark Age: Moloch, Magical Thinking, and the Anti-Scientific Spirit. Stanley Ridgley. https://www.researchgate.net/publication/319112083
Abstract: Much of what is considered bleeding edge theory in sociology today consists of articles propounding theories that cannot be falsified, that are grounded in confirmation bias, that are crafted in a strange and inaccessible argot, and that appeal to pathos in the creation of a Moloch upon which to hang blame for the world’s ills. Any one of these contentions about modern sociological writing could and probably should be the subject of expanded study – taken together, they constitute a tendency in sociology toward a New Metaphysics. This tendency represents a profound change in the modern zeitgeist – a reversal, in fact. We are experiencing a reversal of the ascendancy of science and scientific thinking and a resurgence of medievalist magical thinking about society – how we live, how we exchange with each other, how we are governed. This essay ranges far in this regard and charts a course for further exploration. It examines the rise of the New Metaphysics and its primary means of communicating its ideas. It draws parallels between today’s new metaphysicians and those schoolmen of the middle ages, whose embrace of magic thinking was so complete that its straitened medieval orthodoxy not only hindered scientific, economic, and commercial progress, but also often punished such progress as heretical. Finally, this essay suggests that in its embrace of its own truth and with its “praxis-oriented” posture, the New Metaphysics poses a growing threat to the scholarly traditions of the university and itself constitutes a barbarous pseudo-science that begs unmasking.

According to Popper, the central problem with “theories” of a metaphysical bent was their apparent strength – their explanatory power. This type of theory excites and impresses those exposed to it, and this can lead to a suspension of the critical faculties in favor of what we call today confirmation bias [41; 51]. Popper’s discussion of the matter:
[...]
The rebellion against scientific theory-testing has continued and, if anything, has worsened. The main problem with the path that social science has taken with regard to theory – sociology, in particular – is that theory construction is hamstrung by what we may call the “Popper Problem.” In the archipelago of niche sociological speculation, scholars have all but abandoned the notion that their theories ought to withstand the scrutiny of testing. Rather than a willingness to test rigorously various popular theories that emerged from the heyday of critical theory, which spawned a cottage industry of various “critical” subfields, we find a sort of enshrinement of verification, if not outright confirmation bias. Some subfields, such as “critical race theory,” are founded almost exclusively on confirmation bias.8 Modern theories in sociology spun from critical theory are largely not falsifiable. They are faith-based. As a method of exploration, this is not wholly objectionable. [...]

This type of theory excites and impresses those exposed to it, and this can lead to a suspension of the critical faculties in favor of what we call today confirmation bias [41; 51]. Popper’s discussion of the matter:
These theories appeared to be able to explain practically everything that happened within the fields to which they referred. The study of any of them seemed to have the effect of an intellectual conversion or revelation, opening your eyes to a new truth hidden from those not yet initiated. Once your eyes were thus opened you saw confirming instances everywhere: the world was full of verifications of the theory. Whatever happened always confirmed it. Thus its truth appeared manifest; and unbelievers were clearly people who did not want to see the manifest truth; who refused to see it, either because it was against their class interest, or because of their repressions which were still ‘un-analysed’ and crying aloud for treatment. The most characteristic element in this situation seemed to me the incessant stream of confirmations, of observations which ‘verified’ the theories in question; and this point was constantly emphasize by their adherents. A Marxist could not open a newspaper without finding on every page confirming evidence for his interpretation of history; not only in the news, but also in its presentation – which revealed the class bias of the paper – and especially of course in what the paper did not say.

Cerebral blood flow changes after a day of wake, sleep, & sleep deprivation: There are morning-to-evening increases in cerebral blood flow, reversed by a night of sleep; a night of sleep deprivation is linked to further cerebral blood flow increases
Cerebral blood flow changes after a day of wake, sleep, and sleep deprivation. Torbjørn Elvsåshagen et al. NeuroImage, https://doi.org/10.1016/j.neuroimage.2018.11.032
Highlights
• How cerebral blood flow changes during the sleep-wake cycle remains to be clarified.
• We examined cerebral blood flow after wake, sleep, and sleep deprivation.
• There were morning-to-evening increases in cerebral blood flow.
• These changes were reversed by a night of sleep.
• A night of sleep deprivation was associated with further cerebral blood flow increases.
Abstract: Elucidating the neurobiological effects of sleep and wake is an important goal of the neurosciences. Whether and how human cerebral blood flow (CBF) changes during the sleep-wake cycle remain to be clarified. Based on the synaptic homeostasis hypothesis of sleep and wake, we hypothesized that a day of wake and a night of sleep deprivation would be associated with gray matter resting CBF (rCBF) increases and that sleep would be associated with rCBF decreases. Thirty-eight healthy adult males (age 22.1 ± 2.5 years) underwent arterial spin labeling perfusion magnetic resonance imaging at three time points: in the morning after a regular night's sleep, the evening of the same day, and the next morning, either after total sleep deprivation (n = 19) or a night of sleep (n = 19). All analyses were adjusted for hematocrit and head motion. rCBF increased from morning to evening and decreased after a night of sleep. These effects were most prominent in bilateral hippocampus, amygdala, thalamus, and in the occipital and sensorimotor cortices. Group × time interaction analyses for evening versus next morning revealed significant interaction in bilateral lateral and medial occipital cortices and in bilateral insula, driven by rCBF increases in the sleep deprived individuals and decreases in the sleepers, respectively. Furthermore, group × time interaction analyses for first morning versus next morning showed significant effects in medial and lateral occipital cortices, in anterior cingulate gyrus, and in the insula, in both hemispheres. These effects were mainly driven by CBF increases from TP1 to TP3 in the sleep deprived individuals. There were no associations between the rCBF changes and sleep characteristics, vigilant attention, or subjective sleepiness that remained significant after adjustments for multiple analyses. Altogether, these results encourage future studies to clarify mechanisms underlying sleep-related rCBF changes.

The Joy of Lottery Play: Lottery participation increased the happiness of participants before the draw; winning a small prize had no effect on happiness; it seems that people may not only care about the outcomes of the lottery, but also enjoy the game
The Joy of Lottery Play: Evidence from a Field Experiment. Martijn Burger, Martijn Hendriks, Emma Pleeging, Jan C. van Ours. Tinbergen Institute Discussion Paper TI 2018-078/V, October 23, 2018, http://papers.tinbergen.nl/18078.pdf
Abstract: We conducted a field experiment to increase our understanding of lottery participation. Using representative data for the Netherlands, we find that lottery participation increased the happiness of participants before the draw. Winning a small prize had no effect on happiness. Our results indicate that people may not only care about the outcomes of the lottery, but also enjoy the game. Accordingly, we conclude that lottery play has a utility value in itself and part of the lottery ticket is consumed before the draw.

Time Use and Happiness of Millionaires: Two large-scale surveys of millionaires and the general population show that millionaires spend their time in surprisingly similar ways as the general population
Time Use and Happiness of Millionaires. Paul Smeets, Rene Bekkers, Ashley V. Whillans, Michael Norton. Harvard Business School Working Paper 18-111. https://www.hbs.edu/faculty/Publication%20Files/18-111_401aafe7-dede-4cf9-9d95-073eee6868da.pdf
Abstract: How do the wealthy spend their time, and does their time use relate to their greater well-being? Two large-scale surveys of millionaires and the general population show that millionaires spend their time in surprisingly similar ways as the general population. For example, millionaires spend the same amount of time as the general population cooking, shopping, and eating – and even spend more time on household chores. However, while millionaires and non-millionaires also spend the same amount of time engaging in leisure activities, a critical difference emerged: the wealthy engage in more active leisure (e.g., exercising and volunteering) and less passive leisure (e.g., watching TV and relaxing). Moreover, the extent to which wealthy individuals engage in greater active leisure helps to explain the gap in life satisfaction between millionaires and the general population. Together, these results further our unders tanding of when and how wealth translates into well-being.

Touching narratives motivate to give to charity, and phylosophical arguments have difficulties in this task
Narrative but Not Philosophical Argument Motivates Giving to Charity. Eric Schwitzgebel and Christopher McVey. Provisional results, The Splintered Mind blog, Wednesday, November 21, 2018. schwitzsplinters.blogspot.com/2018/11/narrative-but-not-philosophical.html
We regard this as preliminary evidence that exposure to at least one type of narrative influences charitable giving, motivation, and opinion, while exposure to one common type of philosophical argument has little if any influence.

Early childhood investment impacts social decision-making four decades later
Early childhood investment impacts social decision-making four decades later. Yi Luo, Sébastien Hétu, Terry Lohrenz, Andreas Hula, Peter Dayan, Sharon Landesman Ramey, Libbie Sonnier-Netto, Jonathan Lisinski, Stephen LaConte, Tobias Nolte, Peter Fonagy, Elham Rahmani, P. Read Montague & Craig Ramey. Nature Communications, volume 9, Article number: 4705 (2018). https://www.nature.com/articles/s41467-018-07138-5
Abstract: Early childhood educational investment produces positive effects on cognitive and non-cognitive skills, health, and socio-economic success. However, the effects of such interventions on social decision-making later in life are unknown. We recalled participants from one of the oldest randomized controlled studies of early childhood investment—the Abecedarian Project (ABC)—to participate in well-validated interactive economic games that probe social norm enforcement and planning. We show that in a repeated-play ultimatum game, ABC participants who received high-quality early interventions strongly reject unequal division of money across players (disadvantageous or advantageous) even at significant cost to themselves. Using a multi-round trust game and computational modeling of social exchange, we show that the same intervention participants also plan further into the future. These findings suggest that high quality early childhood investment can result in long-term changes in social decision-making and promote social norm enforcement in order to reap future benefits.

Practicing cognitive-training programs or intellectually demanding activities do not enhance any cognitive skill; at best, such interventions boost one’s performance in tasks similar to the trained task
Cognitive Training Does Not Enhance General Cognition. Giovanni Sala, Fernand Gobet. Trends in Cognitive Sciences, https://doi.org/10.1016/j.tics.2018.10.004
Highlights
* General cognitive ability (GCA) has been consistently found to correlate with performance in cognitive tasks and complex activities such as playing music, board games, and video games.
* In the past two decades, researchers have thus extensively investigated the effects of engaging in cognitive-training programs and intellectually demanding activities on GCA. The results have been mixed.
* Several independent researchers have noticed that the between-study variability can be accounted for by the quality of the experimental design and statistical artifacts. Those studies including large samples and active control groups often report no training-related effects.
* These findings show that practicing cognitive-training programs or intellectually demanding activities do not enhance GCA or any cognitive skill. At best, such interventions boost one’s performance in tasks similar to the trained task.
Abstract: Due to potential theoretical and societal implications, cognitive training has been one of the most influential topics in psychology and neuroscience. The assumption behind cognitive training is that one’s general cognitive ability can be enhanced by practicing cognitive tasks or intellectually demanding activities. The hundreds of studies published so far have provided mixed findings and systematic reviews have reached inconsistent conclusions. To resolve these discrepancies, we carried out several meta-analytic reviews. The results are highly consistent across all the reviewed domains: minimal effect on domain-general cognitive skills. Crucially, the observed between-study variability is accounted for by design quality and statistical artefacts. The cognitive-training program of research has showed no appreciable benefits, and other more plausible practices to enhance cognitive performance should be pursued.

The Failure to Measure Dietary Intake Engendered a Fictional Discourse on Diet-Disease Relations. Edward Archer, Carl J. Lavie and James O. Hill. Front. Nutr., Nov 13 2018 | https://doi.org/10.3389/fnut.2018.00105
Abstract: Controversies regarding the putative health effects of dietary sugar, salt, fat, and cholesterol are not driven by legitimate differences in scientific inference from valid evidence, but by a fictional discourse on diet-disease relations driven by decades of deeply flawed and demonstrably misleading epidemiologic research. Over the past 60 years, epidemiologists published tens of thousands of reports asserting that dietary intake was a major contributing factor to chronic non-communicable diseases despite the fact that epidemiologic methods do not measure dietary intake. In lieu of measuring actual dietary intake, epidemiologists collected millions of unverified verbal and textual reports of memories of perceptions of dietary intake. Given that actual dietary intake and reported memories of perceptions of intake are not in the same ontological category, epidemiologists committed the logical fallacy of “Misplaced Concreteness.” This error was exacerbated when the anecdotal (self-reported) data were impermissibly transformed (i.e., pseudo-quantified) into proxy-estimates of nutrient and caloric consumption via the assignment of “reference” values from databases of questionable validity and comprehensiveness. These errors were further compounded when statistical analyses of diet-disease relations were performed using the pseudo-quantified anecdotal data. These fatal measurement, analytic, and inferential flaws were obscured when epidemiologists failed to cite decades of research demonstrating that the proxy-estimates they created were often physiologically implausible (i.e., meaningless) and had no verifiable quantitative relation to the actual nutrient or caloric consumption of participants. In this critical analysis, we present substantial evidence to support our contention that current controversies and public confusion regarding diet-disease relations were generated by tens of thousands of deeply flawed, demonstrably misleading, and pseudoscientific epidemiologic reports. We challenge the field of nutrition to regain lost credibility by acknowledging the empirical and theoretical refutations of their memory-based methods and ensure that rigorous (objective) scientific methods are used to study the role of diet in chronic disease.

More psychopathic, narcissistic, & Machiavellian individuals possess a reasonable degree of insight into their trait levels & impairment, against theory, which holds that individuals’ ability to recognize the presence, severity, & impact of pathological traits is low
Sleep, Chelsea, Josh Miller, Donald Lynam, and William K. Campbell. 2018. “Antagonism-related Pds Insight & Impairment 11.13.18.” PsyArXiv. November 21. doi:10.31234/osf.io/597h4
Abstract: Clinical theory is skeptical of individuals’ ability to recognize the presence, severity, and impact of clinical symptoms and pathological traits (Oltmanns & Powers, 2012); however, empirical work has found moderate self-other convergence for reports of pathological traits and for Antagonism-related personality disorder (PD) constructs (i.e., psychopathy, narcissism, and Machiavellianism), which are characterized by low insight. Nevertheless, empirical examinations of insight into perceptions of impairment is scant. Thus, the present study sought to examine individuals’ insight regarding pathological traits and related impairment in two samples. In Sample 1, more psychopathic, narcissistic, and Machiavellian individuals reported higher levels of pathological traits and were aware of related impairment. In Sample 2, individuals reported higher levels of pathological traits and, albeit to a lesser degree, more Antagonism-related impairment. Thus, more psychopathic, narcissistic, and Machiavellian individuals possess a reasonable degree of insight into their trait levels and associated impairment.

Overall, both a women’s and her spouse’s income is significantly negatively associated with the woman’s number of children; probability to remain childless increases with increasing own, but decreases with increasing spouse’s income
Effects of woman’s and husband’s income on woman’s reproduction: Darwinian perspectives on human mating. Martin Fieder and Susanne Huber. Front. Sociol. | doi: 10.3389/fsoc.2018.00037
Abstract: From a Darwinian perspective, for women, mate choice may be of crucial importance particularly concerning resources needed for rearing the children. In modern societies, however, resources in terms of income are often provided by both women and men. Nonetheless, the effects of a women’s and her husband’s socio-economic status on woman’s reproduction have not been investigated on a broader level. We therefore aimed to investigate the effects of a women’s and her husband’s income on the women’s number of children and her probability of remaining childless on the basis of census data of 9 contemporary census samples mainly from the developing world, totaling 782,147 women aged 45-54 years and their spouses. Overall, both a women’s and her spouse’s income is significantly negatively associated with the woman’s number of children. Only in Israel, we find a positive association between husband’s income and woman’s offspring number. A woman’s probability to remain childless, however, increases with increasing own, but decreases with increasing spouse’s income. We conclude that in this sample of nearly all developing countries, effects of male social status on woman’s reproduction are acting through childlessness.

Positive affect (PA) was associated with positive interpretations of neutral faces; PA & life satisfaction were associated with positive interpretations of ambiguous and positive, but not negative, social interaction vignettes
Subjective Well-Being, Social Interpretation, and Relationship Thriving. Samantha J. Heintzelman. Ed Diener. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2018.11.007
Highlights
• Happiness related to interpretations of ambiguous social stimuli.
• Happiness did not relate to interpretations of negative situations.
• Positive social interpretations were associated with social thriving.
• Happiness indirectly related to social thriving through social interpretations.
Abstract: Social interactions are open to a range of interpretations. We examine the associations among subjective well-being, social interpretations, and social thriving. In Study 1 (N=276) positive affect (PA) was associated with positive interpretations of neutral faces. In Studies 2 and 3 (Ns=295, 298) PA and life satisfaction were associated with positive interpretations of ambiguous and positive, but not negative, social interaction vignettes. In Study 4 (N=501) there were indirect relationships of PA and life satisfaction on social thriving through interpretations. Subjective well-being’s association with social interpretations provides a critical base of support for conclusions from previous methodologically limited mood and social interpretation studies. This work also provides initial evidence for a role of social interpretation tendencies in social thriving.
Highlights
• Happiness related to interpretations of ambiguous social stimuli.
• Happiness did not relate to interpretations of negative situations.
• Positive social interpretations were associated with social thriving.
• Happiness indirectly related to social thriving through social interpretations.

Rolf Degen summarizing: Yet more evidence that the Implicit Association Test, though to be a neutral test instrument, changes the attitudes it is intended to assess, possibly making the cure worse than the disease
Implicit Association Test as an Analogical Learning Task. Ian Hussey and Jan De Houwer. Experimental Psychology (2018), 65, pp. 272-285. https://doi.org/10.1027/1618-3169/a000416
Abstract. The Implicit Association Test (IAT) is a popular tool for measuring attitudes. We suggest that performing an IAT could, however, also change attitudes via analogical learning. For instance, when performing an IAT in which participants categorize (previously unknown) Chinese characters, flowers, positive words, and negative words, participants could infer that Chinese characters relate to flowers as negative words relate to positive words. This analogy would imply that Chinese characters are opposite to flowers in terms of valence and thus that they are negative. Results from three studies (N = 602) confirmed that evaluative learning can occur when completing an IAT, and suggest that this effect can be described as analogical. We discuss the implications of our findings for research on analogy and research on the IAT as a measure of attitudes.

Further examining the potential association between birth order and personality: Null results from a national sample of American siblings
Further examining the potential association between birth order and personality: Null results from a national sample of American siblings. Cashen M. Boccio, Kevin M. Beaver. Personality and Individual Differences, Volume 139, 1 March 2019, Pages 125-131. https://doi.org/10.1016/j.paid.2018.11.017
Abstract: There has been a body of research examining whether there is an association between birth order and personality traits. The results of these studies have been somewhat mixed, with some findings indicating an association and others reporting no association. Against this backdrop, the current study analyzed data drawn from the National Longitudinal Study of Adolescent to Adult Health to further examine the potential link between birth order and personality (N = 2,508–14,125). The results of both within- and between-family research designs revealed no consistent evidence of a link between birth order and the personality traits of extraversion, neuroticism, agreeableness, conscientiousness, and openness. We discuss certain limitations in our study and offer suggestions for ways to overcome them in future studies.

Do certain personality traits provide a mating market competitive advantage? Sex, offspring & the Big five
Do certain personality traits provide a mating market competitive advantage? Sex, offspring & the big 5. Stephen Whyte, Robert C. Brooks, Ho Fai Chan, Benno Torgler. Personality and Individual Differences, Volume 139, 1 March 2019, Pages 158-169. https://doi.org/10.1016/j.paid.2018.11.019
Abstract: This study uses the BIG 5 personality traits to quantitatively explore correlates of sexual frequency and reproductive success of a large sample (NMale = 2998; NFemale = 1480) of heterosexuals advertised to on an Australian dating website. Consistent with previous research we find that for both sexes, extraversion has a positive linear relationship with sexual frequency. The same is also observable for males that are more conscientious, more emotionally stable, and less agreeable; indicating that for men, a greater number of personality factors matter in explaining the variation in sexual activity. Higher extraversion or lower openness in males correlates with more offspring. Conversely, only more agreeable females have more offspring. Our non-parametric thin-plate spline analysis suggests certain combinations of the traits extraversion & agreeableness, extraversion & conscientiousness, and agreeableness & conscientiousness provide select males a mating market competitive advantage in relation to sexual frequency, compared to other males. Our findings suggest that greater variance in male traits and their particular combinations thereof may provide a fitness comparative advantage for males, but not necessarily for females.

Popular areas of research—brain training, mind-set, grit, deliberate practice, & bilingual advantage—overstate that environmental factors are the overwhelming determinants of success in real-world pursuits
Overstating the Role of Environmental Factors in Success: A Cautionary Note. David Moreau, Brooke N. Macnamara, David Z. Hambrick. Current Directions in Psychological Science, https://doi.org/10.1177/0963721418797300
Abstract: Several currently popular areas of research—brain training, mind-set, grit, deliberate practice, and the bilingual advantage—are premised on the idea that environmental factors are the overwhelming determinants of success in real-world pursuits. Here, we describe the major claims from each of these areas of research and discuss evidence for these claims, particularly focusing on meta-analyses. We suggest that overemphasizing the malleability of abilities and other traits can have negative consequences for individuals, science, and society. We conclude with a call for balanced appraisals of the available evidence concerning this issue, to reflect current scientific discrepancies and thereby enable informed individual decisions and collective policies.

Completing a Race Test Increases Implicit Racial Bias: By measuring, we often perturb the system that we wish to understand
Hussey, Ian, and Jan De Houwer. 2018. “Completing a Race IAT Increases Implicit Racial Bias.” PsyArXiv. November 19. doi:10.31234/osf.io/vxsj7
Abstract: The Implicit Association Test has been used in online studies to assess implicit racial attitudes in over seven million participants. Although typically used as an assessment measure, results from four pre-registered experiments (N = 940) demonstrated that completing a Race IAT exacerbates the negative implicit attitudes that it seeks to assess. Increases in White participants’ negative automatic racial evaluations of Black people were observed across two different implicit measures (SC-IAT and AMP) but did not generalize to another measure of automatic racial bias (Shooter Bias task). Results highlight an important caveat for the Race IAT, but also for many other forms of psychological assessment: that by measuring, we often perturb the system that we wish to understand.

From 2016 > The natural selection of bad science, logical consequences of structural incentives: selection for high output leads to poorer methods and increasingly high false discovery rates
The natural selection of bad science. Paul E. Smaldino, Richard McElreath. Royal Society Open Science, Sep 21 2016. DOI: 10.1098/rsos.160384
Abstract: Poor research design and data analysis encourage false-positive findings. Such poor methods persist despite perennial calls for improvement, suggesting that they result from something more than just misunderstanding. The persistence of poor methods results partly from incentives that favour them, leading to the natural selection of bad science. This dynamic requires no conscious strategizing—no deliberate cheating nor loafing—by scientists, only that publication is a principal factor for career advancement. Some normative methods of analysis have almost certainly been selected to further publication instead of discovery. In order to improve the culture of science, a shift must be made away from correcting misunderstandings and towards rewarding understanding. We support this argument with empirical evidence and computational modelling. We first present a 60-year meta-analysis of statistical power in the behavioural sciences and show that power has not improved despite repeated demonstrations of the necessity of increasing power. To demonstrate the logical consequences of structural incentives, we then present a dynamic model of scientific communities in which competing laboratories investigate novel or previously published hypotheses using culturally transmitted research methods. As in the real world, successful labs produce more ‘progeny,’ such that their methods are more often copied and their students are more likely to start labs of their own. Selection for high output leads to poorer methods and increasingly high false discovery rates. We additionally show that replication slows but does not stop the process of methodological deterioration. Improving the quality of research requires change at the institutional level.
The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.

How mindfulness is currently being invented as a scientific fact or object of inquiry: On the porosity of subject & object in “mindfulness” scientific study, & challenges to “scientific” construction, operationalization & measurement of mindfulness
On the porosity of subject and object in “mindfulness” scientific study: Challenges to “scientific” construction, operationalization and measurement of mindfulness. Paul Grossman. Current Opinion in Psychology, https://doi.org/10.1016/j.copsyc.2018.11.008
Abstract: Mindfulness, derived from Buddhist psychology and philosophy, has gained broad popularity in the last decades, due importantly to scientific interest and findings. Yet Buddhist mindfulness developed in Asian pre-scientific culture and religion, and is predicated upon long-term cultivation of introspective awareness of lived experience, not highly accessible to empirical study. Further complicating the “science” of mindfulness, mindfulness’s very definition is multifaceted, resistant to dismantling and requires substantial amounts of personal practice to gain expertise. Most scientists investigating mindfulness have not achieved a high level of this expertise. Here I address how mindfulness is currently being invented as a scientific fact or object of inquiry. The intrinsic porosity of subjective and objective factors influencing the investigation of mindfulness is highlighted: the evolving body of “scientific” experts, instruments used to measure mindfulness, the alliances of funders and other supporters of mindfulness research, and the public representation of the related findings.

How Hawkish Is the Chinese Public?: The young, netizens & elites are even more inclined to call on the Chinese government to invest and rely more on military strength
Weiss, Jessica Chen, How Hawkish Is the Chinese Public?: Another Look at ‘Rising Nationalism’ and Chinese Foreign Policy (August 31, 2018). Journal of Contemporary China, Forthcoming. https://ssrn.com/abstract=3265588
Abstract: Chinese leaders often invoke the feelings of the Chinese people in denouncing foreign actions in international confrontations. But most survey research on Chinese public opinion on international affairs has looked at measures of nationalist identity rather than beliefs about foreign policy and evaluations of the government’s performance. Five surveys of Chinese citizens, netizens, and elites help illuminate the public attitudes that the Chinese government grapples with in managing international security policy. The results show that Chinese attitudes are more hawkish than dovish and that younger Chinese, while perhaps not more nationalist in identity, may be more hawkish in their foreign policy beliefs than older generations. Netizens and elites are even more inclined to call on the Chinese government to invest and rely more on military strength.

Maria Montessori concluded that pretend play and fantasy were not as helpful for children's development
Pretend Play and Fantasy: What if Montessori Was Right? Angeline S. Lillard, Jessica Taggart. Child Development Perspectives, https://doi.org/10.1111/cdep.12314
Abstract: Pretend play and fantasy are staples of childhood, supported by adults’ provision of encouraging tools (like dress‐up clothing and play kitchens) and by media. Decades ago, Maria Montessori developed a system of education based on close observation of children, and she concluded that pretend play and fantasy were not as helpful for children's development as the zeitgeist suggested (and still suggests). In this article, we present her views and relevant evidence, and ask: What if she was right? What if, as a culture, we are putting great effort and faith into activities and contexts for children that we believe help development but that might actually be less helpful than engaging in the real world?

Access to copulation decreases measures of male sexual motivation when male subjects were visually exposed to the female they had copulated with & this effect is not counteracted by the view of a new female
Effects of a novel partner and sexual satiety on the expression of male sexual behavior and brain aromatase activity in quail. Catherinede Bournonville et al. Behavioural Brain Research, https://doi.org/10.1016/j.bbr.2018.11.026
Abstract: This study was designed to determine whether changes in sexual motivation acutely regulate brain estrogen synthesis by aromatase. Five experiments (Exp.1-5) were first conducted to determine the effect of recent mating and of the presentation of a new female (Coolidge effect) on sexual motivation. Exp.1-2 showed that 10 min or overnight access to copulation decreases measures of male sexual motivation when male subjects were visually exposed to the female they had copulated with and this effect is not counteracted by the view of a new female. Exp.3 showed that sexual motivation is revived by the view of a new female in previously unmated males only allowed to see another female for 10 min. After mating for 10 min (Exp.4) or overnight (Exp.5) with a female, males showed a decrease in copulatory behavior that was not reversed by access to a new female. Exp.6 and 7 confirmed that overnight copulation (Exp.6) and view of a novel female (Exp.7) respectively decreases and increases sexual behavior and motivation. Yet, these manipulations did not affect brain aromatase activity except in the tuberal hypothalamus. Together these data confirm that copulation or prolonged view of a female decrease sexual motivation but a reactivation of sexual motivation by a new female can only be obtained if males had only seen another female but not copulated with her, which is different in some degree from the Coolidge effect described in rodents. Moreover changes in brain aromatase do not simply reflect changes in motivation and more complex mechanisms must be considered.

For the dreamer, the dream world is the real world, best explained in terms of the concept of mental ownership: the exogenous nature of that narrative is the result of an individual assuming perspectival, not personal, ownership of the content
B. Klein, Stan. (2018). The phenomenology of REM-sleep dreaming: The contributions of personal and perspectival ownership, subjective temporality, and episodic memory. Psychology of Consciousness: Theory, Research, and Practice. 10.1037/cns0000174
Abstract: Although the dream narrative, of (bio)logical necessity, originates with the dreamer, he or she typically is not aware of this. For the dreamer, the dream world is the real world. In this article, I argue that this nightly misattribution is best explained in terms of the concept of mental ownership (e.g., Albahari, 2006; Klein, 2015a; Lane, 2012). Specifically, the exogenous nature of the dream narrative is the result of an individual assuming perspectival, but not personal, ownership of the content she or he authored (i.e., “The content in my head is not mine. Therefore it must be peripherally perceived”). Situating explanation within a theoretical space designed to address questions pertaining to the experienced origins of conscious content has a number of salutary consequences. For example, it promotes predictive fecundity by bringing to light empirical generalizations whose presence otherwise might have gone unnoticed (e.g., the severely limited role of mental time travel within the dream narrative).

Saving regret (the wish in hindsight to have saved more earlier in life): little of the variation is explained by procrastination & psychological factors; unemployment, health & divorce explain much more
Saving Regret. Axel H. Börsch-Supan, Tabea Bucher-Koenen, Michael D. Hurd, Susann Rohwedder. NBER Working Paper No. 25238, Nov 2018. https://www.nber.org/papers/w25238
Abstract: We define saving regret as the wish in hindsight to have saved more earlier in life. We measured saving regret and possible determinants in a survey of a probability sample of those aged 60-79. We investigate two main causes of saving regret: procrastination along with other psychological traits, and the role of shocks, both positive and negative. We find high levels of saving regret but relatively little of the variation is explained by procrastination and psychological factors. Shocks such as unemployment, health and divorce explain much more of the variation. The results have important implications for retirement saving policies.

Gene discovery & polygenic prediction from a genome-wide association study in 1.1 million individuals: Explain 11–13% of the variance in educational attainment & 7–10% in cognitive performance
Gene discovery and polygenic prediction from a genome-wide association study of educational attainment in 1.1 million individuals. James J. Lee et al. Nature Genetics, volume 50, pages1112–1121 (Jul 2018). https://www.nature.com/articles/s41588-018-0147-3
Abstract: Here we conducted a large-scale genetic association analysis of educational attainment in a sample of approximately 1.1 million individuals and identify 1,271 independent genome-wide-significant SNPs. For the SNPs taken together, we found evidence of heterogeneous effects across environments. The SNPs implicate genes involved in brain-development processes and neuron-to-neuron communication. In a separate analysis of the X chromosome, we identify 10 independent genome-wide-significant SNPs and estimate a SNP heritability of around 0.3% in both men and women, consistent with partial dosage compensation. A joint (multi-phenotype) analysis of educational attainment and three related cognitive phenotypes generates polygenic scores that explain 11–13% of the variance in educational attainment and 7–10% of the variance in cognitive performance. This prediction accuracy substantially increases the utility of polygenic scores as tools in research.

Associations & civil society as key factors in a healthy liberal democracy: do individuals who are members of civil associations vote less for populist parties?; & does membership in associations decrease when populist parties are in power?
Populism and Civil Society. Tito Boeri; Prachi Mishra; Chris Papageorgiou; Antonio Spilimbergo. Int'l Monetary Fund, Working Paper No. 18/245, Nov 16, 2018. https://www.imf.org/en/Publications/WP/Issues/2018/11/17/Populism-and-Civil-Society-46324
Summary: Populists claim to be the only legitimate representative of the people. Does it mean that there is no space for civil society? The issue is important because since Tocqueville (1835), associations and civil society have been recognized as a key factor in a healthy liberal democracy. We ask two questions: 1) do individuals who are members of civil associations vote less for populist parties? 2)does membership in associations decrease when populist parties are in power? We answer thesequestions looking at the experiences of Europe, which has a rich civil society tradition, as well as of Latin America, which already has a long history of populists in power. The main findings are that individuals belonging to associations are less likely by 2.4 to 4.2 percent to vote for populist parties, which is large considering that the average vote share for populist parties is from 10 to 15 percent. The effect is strong particularly after the global financial crisis, with the important caveat that membership in trade unions has unclear effects.

Active-sampling policies & their relation to attention & curiosity: Sampling & search depend on individual preferences over cognitive states, including attitudes towards uncertainty, learning progress & types of information
Towards a neuroscience of active sampling and curiosity. Jacqueline Gottlieb & Pierre-Yves Oudeyer. Nature Reviews Neuroscience, volume 19, pages758–770 (2018), https://www.nature.com/articles/s41583-018-0078-0
Abstract: In natural behaviour, animals actively interrogate their environments using endogenously generated ‘question-and-answer’ strategies. However, in laboratory settings participants typically engage with externally imposed stimuli and tasks, and the mechanisms of active sampling remain poorly understood. We review a nascent neuroscientific literature that examines active-sampling policies and their relation to attention and curiosity. We distinguish between information sampling, in which organisms reduce uncertainty relevant to a familiar task, and information search, in which they investigate in an open-ended fashion to discover new tasks. We review evidence that both sampling and search depend on individual preferences over cognitive states, including attitudes towards uncertainty, learning progress and types of information. We propose that, although these preferences are non-instrumental and can on occasion interfere with external goals, they are important heuristics that allow organisms to cope with the high complexity of both sampling and search, and generate curiosity-driven investigations in large, open environments in which rewards are sparse and ex ante unknown.

Generational changes in personality & frequencies of individual words 1900-2002: Modest increase for Extraversion-, Agreeableness-, and Stability-related adjectives; Intellect-related words increased up to 1960, then declined
Generational Changes in Personality: The Evidence From Corpus Linguistics. Eka Roivainen. Psychological Reports, https://doi.org/10.1177/0033294118805937
Abstract: According to theory, social change is interconnected with changes in mental phenomena and language. In the present study, secular change in the usage frequencies of common English personality adjectives (n = 336) qualifying the word person was analyzed over the period 1900 to 2002. It was hypothesized that words that represent those personality traits that are advantageous in occupations typical for modern societies have increased in frequency. The results show changes in the frequencies of individual words but stability across the five major categories of trait adjectives in the Google Books English fiction corpus. A modest increase for Extraversion-, Agreeableness-, and Stability-related adjectives was observed in the Google Books English 2012 corpus. Frequency of Intellect-related words increased up to 1960 and then declined. The results suggest that (a) human nature has changed little over the 20th century, (b) generational changes in personality are not strongly reflected in language, or (c) the corpus linguistic method used is not reliable for studying generational changes in personality.

I’m not the person I used to be: Bad actions that happened further in the past are more morally wrong than those that happened more recently
Stanley, M. L., Henne, P., Iyengar, V., Sinnott-Armstrong, W., & De Brigard, F. (2017). I’m not the person I used to be: The self and autobiographical memories of immoral actions. Journal of Experimental Psychology: General, 146(6), 884-895. http://dx.doi.org/10.1037/xge0000317
Abstract: People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time.

Corrigendum to “The neural correlates of moral decision-making: A systematic review and meta-analysis of moral evaluations and response decision judgements” in Brain and Cognition, Volume 111, February 2017, Pages 104-106
Highlights
• We compared brain activation when making your own moral decision or when evaluating another’s decision.
• We included 28 experiments and used activation likelihood estimate analysis.
• The left middle temporal gyrus, cingulate gyrus, and medial frontal gyrus was active for both types of decisions.
• Making your own decision also activated the left and right middle temporal gyrus and the right precuneus.
• Making a decision about yourself involves additional brain areas.
Abstract: The aims of this systematic review were to determine: (a) which brain areas are consistently more active when making (i) moral response decisions, defined as choosing a response to a moral dilemma, or deciding whether to accept a proposed solution, or (ii) moral evaluations, defined as judging the appropriateness of another’s actions in a moral dilemma, rating moral statements as right or wrong, or identifying important moral issues; and (b) shared and significantly different activation patterns for these two types of moral judgements. A systematic search of the literature returned 28 experiments. Activation likelihood estimate analysis identified the brain areas commonly more active for moral response decisions and for moral evaluations. Conjunction analysis revealed shared activation for both types of moral judgement in the left middle temporal gyrus, cingulate gyrus, and medial frontal gyrus. Contrast analyses found no significant clusters of increased activation for the moral evaluations-moral response decisions contrast, but found that moral response decisions additionally activated the left and right middle temporal gyrus and the right precuneus. Making one’s own moral decisions involves different brain areas compared to judging the moral actions of others, implying that these judgements may involve different processes.
Arguably this is causal evidence that teacher expectations affect students' educational attainment
Teacher Expectations Matter. Nicholas W. Papageorge, Seth Gershenson, Kyung Min Kang. NBER Working Paper No. 25255, Nov 2018. https://www.nber.org/papers/w25255
Abstract: We develop and estimate a joint model of the education and teacher-expectation production functions that identifies both the distribution of biases in teacher expectations and the impact of those biases on student outcomes via self-fulfilling prophecies. Our approach leverages a unique feature of a nationally representative dataset: two teachers provided their educational expectations for each student. Identification of causal effects exploits teacher disagreements about the same student, an idea we formalize using lessons from the measurement error literature. We provide novel, arguably causal evidence that teacher expectations affect students' educational attainment: Estimates suggest an elasticity of college completion with respect to teachers' expectations of about 0.12. On average, teachers are overly optimistic about students' ability to complete a four-year college degree. However, the degree of over-optimism of white teachers is significantly larger for white students than for black students. This highlights a nuance that is frequently overlooked in discussions of biased beliefs: less biased (i.e., more accurate) beliefs can be counterproductive if there are positive returns to optimism or if there are socio-demographic gaps in the degree of teachers' optimism; we find evidence of both.

Greater frequency of group sex is associated with buying sex, sex with an injection drug user, being high during sex, condomless vaginal sex, victimization history, & sexually transmitted infection incidence
Frequency of Group Sex Participation and Risk for HIV/STI Among Young Adult Nightclub Scene Participants. Mance E. Buttram, Maria E. Pagano & Steven P. Kurtz. International Journal of Sexual Health, Volume 30, 2018 - Issue 1, Pages 12-19. https://doi.org/10.1080/19317611.2017.1385561
ABSTRACT: Objectives: This study examines frequency of group sex participation and associated characteristics and behaviors among a sample of heterosexual young adult participants in Miami's nightclub scene (n = 498).
Methods: Baseline survey assessments were analyzed using zero-inflated binomial regression.
Results: Forty-one percent of the sample reported group sex participation history. Greater frequency of group sex is associated with buying sex, sex with an injection drug user, being high during sex, condomless vaginal sex, victimization history, and sexually transmitted infection incidence (p < .02).
Conclusions: Sexually transmitted infection prevention and intervention efforts should address risks associated with group sex participation.

Orgasm Range and Variability in Humans: Among others, exercise, sleep, drug use, riding in vehicles & rollercoasters, breastfeeding, eating, reading, defecating, auditory stimulation, childbirth, getting tattoed or pierced
Orgasm Range and Variability in Humans: A Content Analysis. Debby Herbenick, Katie Barnhart, Karly Beavers & Dennis Fortenberry. International Journal of Sexual Health, https://www.tandfonline.com/doi/abs/10.1080/19317611.2018.1491920
Abstract: Orgasm frequently occurs from sexual and/or genital stimulation but has been documented outside these contexts and may be better conceptualized as a set of neuropsychological processes.
Objective: To document a range of orgasm experiences.
Methods: A content analysis of 687 anonymously posted online comments related to nonsexual orgasms.
Results: Orgasm types include those related to exercise, sleep, drug use, riding in vehicles, breastfeeding, eating, auditory stimulation, and childbirth, among others.
Conclusions: Orgasm is experienced in association with varied forms of sensory stimulation. This study provides information about the diversity of human orgasm, informing sex education, therapy, and practice.

Participants were provided with a list of racist behaviors that purportedly were enacted from a fellow student but in fact were based on the participants’ own behaviors; consistently evaluated themselves as less racist
Examining the asymmetry in judgments of racism in self and others. Angela C. Bell, Melissa Burkley & Jarrod Bock. The Journal of Social Psychology, https://www.tandfonline.com/doi/abs/10.1080/00224545.2018.1538930
ABSTRACT: Across three experiments, participants were provided with a list of racist behaviors that purportedly were enacted from a fellow student but in fact were based on the participants’ own behaviors. People consistently evaluated themselves as less racist than this comparison other, even though this other’s racist behaviors were identical to their own. Studies 2a and 2b demonstrate this effect is quite robust and even occurs under social pressure and social consensus conditions in which participants were free to express their racial biases. Thus, it appears that people are less likely to base their racist trait ratings on behavioral evidence when evaluating themselves compared to when they are evaluating another. Taken together, this work provides evidence for the consistency and robustness of self-enhanced social comparisons as applied to the trait domain of racism. Further, this work sheds insight into why people deny they are racist when they act racist.

The effects of parental divorce on individuals’ commitment to same-sex relationships
The effects of parental divorce on individuals’ commitment to same-sex relationships. Lisa M. Godfrey, Amanda D. Kuryluk & Sarah W. Whitton. Marriage & Family Review, Volume 54, 2018 - Issue 8, Pages 806-818. https://doi.org/10.1080/01494929.2018.1503988
Abstract: Research on the intergenerational transmission of divorce has demonstrated that individuals who come from divorced families have reduced commitment to the institution of marriage, which may translate to reduced commitment to one’s current relationship. We tested the association between two components of relationship commitment (dedication and constraint) and parental divorce in a sample of 251 adults in same-sex relationships. Results demonstrated that parental divorce was significantly associated with lower dedication commitment among women, but not men. Parental divorce was not associated with constraint commitment for either gender. These findings suggest that, consistent with research on individuals in different-sex relationships, women in same-sex relationships who come from divorced families may feel less dedicated to their own relationships, putting them at greater risk for relationship instability and divorce.

When given an opportunity to release the robots from restrainers, as they do for conspecifics, we found that rats did release the robots, & moreover, were significantly more likely to release helpful than unhelpful robots

Abstract: Robots are increasingly being used to monitor and even participate in social interactions with animals in their own environments. Robotic animals enable social behaviors to be observed in natural environments, or specifically elicited under the control of an experimenter. It is an open question to what extent animals will form positive social connections with such robots. To test this, we familiarized rats to two rat-sized robots, one exhibiting “social” behaviors, including helping, while the other was also mobile but not helpful. When given an opportunity to release the robots from restrainers, as they do for conspecifics, we found that rats did release the robots, and moreover, were significantly more likely to release the helpful than the unhelpful robot. These findings indicate that robots can elicit helpful behavior from rats, and that rats will even discriminate between robots on the basis of their behaviors.

Gender differences were smaller than previously theorized, with 10.3% of men and 7.0% of women endorsing clinically relevant levels of distress or impairment associated with difficulty controlling sexual feelings, urges, & behavior
Prevalence of Distress Associated With Difficulty Controlling Sexual Urges, Feelings, and Behaviors in the United States. Janna A. Dickenson et al. JAMA Netw Open. 2018;1(7):e184468. doi:10.1001/jamanetworkopen.2018.4468
Key Points
Question What is the prevalence among US men and women of the primary feature of compulsive sexual behavior disorder, distress and impairment associated with having difficulty controlling one’s sexual feelings, urges, and behaviors?
Findings In this survey study, we found that 8.6% of the nationally representative sample (7.0% of women and 10.3% of men) endorsed clinically relevant levels of distress and/or impairment associated with difficulty controlling sexual feelings, urges, and behaviors.
Meaning The high prevalence of such symptoms has major public health relevance as a sociocultural problem and indicates a significant clinical problem that should be recognized by health care professionals.
Abstract
Importance The veracity, nomenclature, and conceptualizations of sex addiction, out-of-control sexual behavior, hypersexual behavior, and impulsive or compulsive sexual behavior are widely debated. Despite such variation in conceptualization, all models concur on the prominent feature: failing to control one’s sexual feelings and behaviors in a way that causes substantial distress and/or impairment in functioning. However, the prevalence of the issue in the United States is unknown.
Objective To assess the prevalence of distress and impairment associated with difficulty controlling sexual feelings, urges, and behaviors among a nationally representative sample in the United States.
Design, Setting, and Participants This survey study used National Survey of Sexual Health and Behavior data to assess the prevalence of distress and impairment associated with difficulty controlling sexual feelings, urges, and behaviors and determined how prevalence varied across sociodemographic variables. Participants between the ages of 18 and 50 years were randomly sampled from all 50 US states in November 2016.
Main Outcomes and Measures Distress and impairment associated with difficulty controlling sexual feelings, urges, and behavior were measured using the Compulsive Sexual Behavior Inventory–13. A score of 35 or higher on a scale of 0 to 65 indicated clinically relevant levels of distress and/or impairment.
Results Of 2325 adults (1174 [50.5%] female; mean [SD] age, 34.0 [9.3] years), 201 [8.6%] met the clinical screen cut point of a score of 35 or higher on the Compulsive Sexual Behavior Inventory. Gender differences were smaller than previously theorized, with 10.3% of men and 7.0% of women endorsing clinically relevant levels of distress and/or impairment associated with difficulty controlling sexual feelings, urges, and behavior.
Conclusions and Relevance The high prevalence of this prominent feature associated with compulsive sexual behavior disorder has important implications for health care professionals and society. Health care professionals should be alert to the high number of people who are distressed about their sexual behavior, carefully assess the nature of the problem within its sociocultural context, and find appropriate treatments for both men and women.

Strategies people spontaneously use in their everyday lives to regulate their persistence during aversive activities; trait self-control & strategy use appear to represent separate routes to good self-regulation
Hennecke, Marie, Thomas Czikmantori, and Veronika Brandstätter. 2018. “Doing Despite Disliking: Self-regulatory Strategies in Everyday Aversive Activities.” PsyArXiv. November 7. doi:10.31234/osf.io/ps7fk > https://onlinelibrary.wiley.com/doi/10.1002/per.2182
Abstract: We investigated the self-regulatory strategies people spontaneously use in their everyday lives to regulate their persistence during aversive activities. In pilot studies (pooled N = 794), we identified self-regulatory strategies from self-reports and generated hypotheses about individual differences in trait self-control predicting their use. Next, deploying ambulatory assessment (N = 264, 1940 reports of aversive/challenging activities), we investigated predictors of the strategies’ self-reported use and effectiveness (trait self-control, demand types). The popularity of strategies varied across demands. In addition, people higher in trait self-control were more likely to focus on the positive consequences of a given activity, set goals, and use emotion regulation. Focusing on positive consequences, focusing on negative consequences (of not performing the activity), thinking of the near finish, and emotion regulation increased perceived self-regulatory success across demands, whereas distracting oneself from the aversive activity decreased it. None of these strategies, however, accounted for the beneficial effects of trait self-control on perceived self-regulatory success. Hence, trait self-control and strategy use appear to represent separate routes to good self-regulation. By considering trait- and process-approaches, these findings promote a more comprehensive understanding of self-regulatory success and failure during people’s daily attempts to regulate their persistence.

Thoughts about the present were common during social interaction, felt pleasant, but lacked to meaningfulness; about the past were relatively unpleasant and involuntary
Baumeister, Roy. 2018. “Everyday Thoughts in Time: Experience Sampling Studies of Mental Time Travel.” PsyArXiv. October 2. doi:10.31234/osf.io/3cwre
Abstract: Time is an important yet mysterious aspects of human conscious experience. We investigated time in everyday thoughts. Two community samples, contacted at random points for three (Study 1; 6,686 reports) and 14 days (Study 2; 2,361 reports), reported on their most recent thought. Both studies found that thoughts about the present and future were frequent, whereas thoughts about the past were rare. Thoughts about the present were common during social interaction, felt pleasant, but lacked to meaningfulness. Thoughts about the future included desires to satisfy goals and usually involved planning. Thoughts about the past were relatively unpleasant and involuntary. Subjective experiences of past and future thoughts often were similar and differed from present focus, consistent with views that memory and prospection use similar mental structures. Taken together, the present work provides unique insights into the conscious experience of time highlights the pragmatic utility of future thought.

Though women are generally more liberal than men, on marijuana legalization are more conservative; best explanations are women's greater religiosity and men's greater drug use
Gender and the Politics of Marijuana. Laurel Elder, Steven Greene. Social Science Quarterly, https://doi.org/10.1111/ssqu.12558
Abstract
Objectives: The objectives of this study were to understand why, even though women are more liberal than men on a broad range of issues, when it comes to the increasingly prominent issue of marijuana legalization, the direction of the gender gap is reversed, with women more conservative than men.
Methods: Relying on a 2013 Pew survey—unique for the extensiveness of its marijuana questions, including marijuana usage—we explore and attempt to explain the nature of this unusual gender gap. We test several hypotheses rooted in the different life experiences of women and men.
Results: We find that women's role as mothers cannot explain this gap, and that mothers are in fact no different from those without children in terms of their support for marijuana policy, as well as their reported use of marijuana. The greater religiosity of women does play a prominent role in the gender gap on marijuana policy, but does not account for the full difference of opinion between women and men. Our findings suggest that men's greater propensity relative to women to use marijuana is a major driver behind the gender gap.
Conclusions: Not only are attitudes on marijuana legalization likely to continue to liberalize, but as marijuana legalization and marijuana use become normalized, rather than viewed as immoral and dangerous behavior, the existing gender gap should shrink.

Rats prefer social interaction to drug addiction
Volitional social interaction prevents drug addiction in rat models. Marco Venniro, Michelle Zhang, Daniele Caprioli, Jennifer K. Hoots, Sam A. Golden, Conor Heins, Marisela Morales, David H. Epstein & Yavin Shaham. Nature Neuroscience, volume 21, pages1520–1529 (2018). https://www.nature.com/articles/s41593-018-0246-6
Abstract: Addiction treatment has not been appreciably improved by neuroscientific research. One problem is that mechanistic studies using rodent models do not incorporate volitional social factors, which play a critical role in human addiction. Here, using rats, we introduce an operant model of choice between drugs and social interaction. Independent of sex, drug class, drug dose, training conditions, abstinence duration, social housing, or addiction score in Diagnostic & Statistical Manual IV-based and intermittent access models, operant social reward prevented drug self-administration. This protection was lessened by delay or punishment of the social reward but neither measure was correlated with the addiction score. Social-choice-induced abstinence also prevented incubation of methamphetamine craving. This protective effect was associated with activation of central amygdala PKCδ-expressing inhibitory neurons and inhibition of anterior insular cortex activity. These findings highlight the need for incorporating social factors into neuroscience-based addiction research and support the wider implantation of socially based addiction treatments.

Pet dogs, like all other tested animals, appear to be unable to learn a seemingly simple lesson: That less can mean more
Any reward will do: Effects of a reverse-reward contingency on size preference with pet dogs (Canis lupus familiaris). Jonathan K. Fernand, Haleh Amanieh, David J. Cox, Nicole R. Dorey. Learning & Behavior, https://link.springer.com/article/10.3758/s13420-018-0343-0
Abstract: The reverse-reward contingency (RRC) task involves presenting subjects with a choice between one plate containing a large amount of food and a second plate containing a small amount of food. Subjects are then required to select the smaller of the two options in order to receive the larger-magnitude reward. The RRC task is a commonly used paradigm for assessing complex cognition, such as inhibitory control, in subjects. To date, the RRC task has not been tested with pet dogs as subjects, and it may provide insights to their ability to perceive quantities of differing magnitudes. Nine dogs were tested in an RRC task involving three conditions. In Condition 1, plates of food were presented, and the dogs were allowed to consume their choice. In Condition 2, plates with different-sized symbols resembling the quantities of food in Condition 1 were presented, and dogs received food quantities of the same size as their choice (e.g., a larger-magnitude reward for selecting the plate with the larger shape). In Condition 3, the same plates were presented, but dogs received a reverse-sized quantity of food, relative to their choice (e.g., a smaller-magnitude reward for selecting the plate with the larger shape). A novel addition here to the traditional RRC task was the inclusion of a third, empty (control) plate that was present throughout all conditions, and no programmed consequences were provided when that plate was selected. Our results were consistent with the previous RRC literature: All dogs developed and maintained a preference for the larger stimulus option across conditions. The use of symbolic representations did not ameliorate performance on the RRC task. Applied implications are discussed.

This evidence supports the view that financial cycles are a recurrent and inherent feature of the financial system, strengthening the case for macroprudential and monetary policies that lean against the wind
Measuring financial cycle time. Andrew Filardo, Marco Jacopo Lombardi and Marek Raczko. BIS Working Papers, No 755, Nov 14 2018. https://www.bis.org/publ/work755.htm
Summary
Focus: Even though the Great Financial Crisis sparked interest in financial cycles, researchers and policymakers have yet to forge a workhorse model. One reason is the disagreement about key factors leading to the crisis. While some argue it resulted from a unique set of developments that exposed weaknesses in the financial regulatory system, others point to broad similarities across past boom-bust experiences. They infer from these similarities that cycles are an inherent feature of financially liberalised economies. We look at broad historical swings in financial cycles to weigh up these views.
Contribution: This paper adds a new perspective to the literature on empirical financial cycles. It highlights the recurring and inherent nature of swings in financial conditions, which result in costly booms and busts. However, this characterisation does not appear so obvious when looking at conventionally plotted historical data (that is, observed in calendar time). We shed light on the facts by distinguishing between financial cycles in calendar time and in what we call "financial cycle time".
Findings: Extending the methods pioneered by James Stock (1987) in his study of business cycles, we find that historical swings in the financial cycle exhibit statistical time deformation, which is time-varying. Changes in this gap between calendar time and financial cycle time are strongly associated with time-varying macrofinancial risk perceptions. Key risk indicators include the long-term real interest rate, inflation volatility and corporate credit spreads. The implications for statistical modelling, endogenous risk-taking economic behaviour and policy are highlighted. This evidence supports the view that financial cycles are a recurrent and inherent feature of the financial system, strengthening the case for macroprudential and monetary policies that lean against the wind.
Abstract: Motivated by the traditional business cycle approach of Burns and Mitchell (1946), we explore cyclical similarities in financial conditions over time in order to improve our understanding of financial cycles. Looking back at 120 years of data, we find that financial cycles exhibit behaviour characterised by recurrent, endogenous swings in financial conditions, which result in costly booms and busts. Yet the recurrent nature of such swings may not appear so obvious when looking at conventionally plotted time-series data (that is, observed in calendar time). Using the pioneering framework developed by Stock (1987), we offer a new statistical characterisation of the financial cycle using a continuous-time autoregressive model subject to time deformation, and test for systematic differences between calendar and a new notion of financial cycle time. We find the time deformation to be statistically significant, and associated with levels of long-term real interest rates, inflation volatility and the perceived riskiness of the macro-financial environment. Implications for statistical modelling, endogenous risk-taking economic behaviour and policy are highlighted.

More attractive faces—especially of the other sex—were looked at longer; the more sociosexually unrestricted participants who were single had the highest attractiveness-attention correlation
How relationship status and sociosexual orientation influence the link between facial attractiveness and visual attention. Aleksandra Mitrovic, Juergen Goller, Pablo P. L. Tinio, Helmut Leder. PLOS One, Nov 14, 2018. https://doi.org/10.1371/journal.pone.0207477
Abstract: Facial attractiveness captures and binds visual attention, thus affecting visual exploration of our environment. It is often argued that this effect on attention has evolutionary functions related to mating. Although plausible, such perspectives have been challenged by recent behavioral and eye-tracking studies, which have shown that the effect on attention is moderated by various sex- and goal-related variables such as sexual orientation. In the present study, we examined how relationship status and sociosexual orientation moderate the link between attractiveness and visual attention. We hypothesized that attractiveness leads to longer looks and that being single as well as being more sociosexually unrestricted, enhances the effect of attractiveness. Using an eye-tracking free-viewing paradigm, we tested 150 heterosexual men and women looking at images of urban real-world scenes depicting two people differing in facial attractiveness. Participants additionally provided attractiveness ratings of all stimuli. We analyzed the correlations between how long faces were looked at and participants’ ratings of attractiveness and found that more attractive faces—especially of the other sex—were looked at longer. We also found that more sociosexually unrestricted participants who were single had the highest attractiveness-attention correlation. Our results show that evolutionary predictions cannot fully explain the attractiveness-attention correlation; perceiver characteristics and motives moderate this relationship.

People who were either not religious at all or very religious were the ones who most supported the killing of animals; belief in God in itself was related to less support for killing animals
Religiosity and Support for Killing Animals: Evidence of a Curvilinear Relationship. Uri Lifshin, Jeff Greenberg & Daniel Sullivan. Anthrozoös, Pages 695-709. https://doi.org/10.1080/08927936.2018.1529352
ABSTRACT: Prior research shows that the correlation between religiosity and support for animal rights can be positive, negative, or zero. We hypothesized that this relationship may actually be curvilinear, where a moderate degree of religiosity may reduce support for killing animals (compared with non-religiosity or atheism), but a very high degree of religiosity (e.g., fundamentalism) might increase support for killing animals. We tested this hypothesis in a large sample of American undergraduate students, using a correlational study design with self-report measures of religiosity and of support for killing animals in different domains. The results indicated that, in support of our hypothesis, the relationship between religiosity and support for killing animals is curvilinear, as moderate levels of religiosity were related to less support for killing animals. People who were either not religious at all or very religious were the ones who most supported the killing of animals. Belief in God in itself was related to less support for killing animals. We then replicated the curvilinear relationship between religiosity and support for killing animals using data from four experiments from a previously published article on support for killing animals. We briefly consider possible explanations for these findings, the limitations of the study, and propose directions for future research. Overall, we believe that this study helps clarify the complex relationship between religiosity and support for killing animals, and advances the scientific understanding of the psychological forces that motivate people to support or object to the killing of animals.

The 2000s should be seen as an exceptional period in the global economy during which multinational firms benefitted from reduced labour costs through offshoring, while capitalising on existing firm-specific intangibles (brand names) at little marginal cost
Factor Incomes in Global Value Chains: The Role of Intangibles. Wen Chen, Bart Los, Marcel P. Timmer. NBER Working Paper No. 25242, https://www.nber.org/papers/w25242
Abstract: Recent studies document a decline in the share of labour and a simultaneous increase in the share of residual (‘factorless’) income in national GDP. We argue the need for study of factor incomes in cross-border production to complement country studies. We define a GVC production function that tracks the value added in each stage of production in any country-industry. We define a new residual as the difference between the value of the final good and the payments to all tangibles (capital and labour) in any stage. We focus on GVCs of manufactured goods and find the residual to be large. We interpret it as income for intangibles that are (mostly) not covered in current national accounts statistics. We document decreasing labour and increasing capital income shares over the period 2000-14. This is mainly due to increasing income for intangible assets, in particular in GVCs of durable goods. We provide evidence that suggests that the 2000s should be seen as an exceptional period in the global economy during which multinational firms benefitted from reduced labour costs through offshoring, while capitalising on existing firm-specific intangibles, such as brand names, at little marginal cost.

Altruistic indulgence: people voluntarily consume high-calorie foods to make other people feel comfortable and pleasant instead of guilty
Altruistic indulgence: people voluntarily consume high-calorie foods to make other people feel comfortable and pleasant. Youjae Yi, Jacob C. Lee & Saetbyeol Kim. Social Influence, https://doi.org/10.1080/15534510.2018.1546616
ABSTRACT: We explored a novel phenomenon where people in certain social contexts voluntarily consume high-calorie foods with the altruistic motive of making other people feel comfortable and pleasant. We hypothesized that people are likely to choose a high-calorie food, especially around others with whom they have communal relationships (e.g., friends), because of the desire to induce in others feelings of pleasantness rather than guilt. A field study at a café shows that this phenomenon emerges in the real world, and a scenario-based experiment supports our altruistic account with mediation analyses. The alternative explanation of a social acceptance account is ruled out.

Aging and Decision-Making: A Conceptual Framework for Future Research
Aging and Decision-Making: A Conceptual Framework for Future Research - A Mini-Review. C E Löckenhoff. Gerontology 2018;64:140-148. https://doi.org/10.1159/000485247
Abstract: Age differences in decision-making are of theoretical interest and have important practical implications, but relevant lines of work are distributed across multiple disciplines and often lack integration. The present review proposes an overarching conceptual framework with the aim of connecting disjointed aspects of this field of research. The framework builds on process models of decision-making and specifies potential mechanisms behind age effects as well as relevant moderators including task characteristics and contextual factors. After summarizing the extant literature for each aspect of the framework, compensatory mechanisms and ecological fit between different components of the model are considered. Implications for real-life decision-making, remaining research gaps, and directions for future research are discussed.

Psychoanalytic as well as cognitive-behavioural long-term treatments lead to significant and sustained improvements of depressive symptoms of chronically depressed patients exceeding effect sizes of other international outcome studies
Outcome of Psychoanalytic and Cognitive-Behavioural Long-Term Therapy with Chronically Depressed Patients: A Controlled Trial with Preferential and Randomized Allocation. Marianne Leuzinger-Bohleber et al. The Canadian Journal of Psychiatry, https://doi.org/10.1177/0706743718780340
Abstract
Objective: For chronic depression, the effectiveness of brief psychotherapy has been limited. This study is the first comparing the effectiveness of long-term cognitive-behavioural therapy (CBT) and long-term psychoanalytic therapy (PAT) of chronically depressed patients and the effects of preferential or randomized allocation.
Methods: A total of 252 adults met the inclusion criteria (aged 21-60 years, major depression, dysthymia, double depression for at least 24 months, Quick Inventory of Depressive Symptoms [QIDS] >9, Beck Depression Inventory II [BDI] >17, informed consent, not meeting exclusion criteria). Main outcome measures were depression self-rating (BDI) and rating (clinician-rated QIDS [QIDS-C]) by independent, treatment-blinded clinicians. Full remission rates (BDI ≤12, QIDS-C ≤5) were calculated. An independent center for data management and biostatistics analyzed the treatment effects and differences using linear mixed models (multilevel models and hierarchical models).
Results: The average BDI declined from 32.1 points by 12.1 points over the first year and 17.2 points over 3 years. BDI overall mean effect sizes increased from d = 1.17 after 1 year to d = 1.83 after 3 years. BDI remission rates increased from 34% after 1 year to 45% after 3 years. QIDS-C overall effect sizes increased from d = 1.56 to d = 2.08, and remission rates rose from 39% after 1 year to 61% after 3 years. We found no significant differences between PAT and CBT or between preferential and randomized allocation.
Conclusions: Psychoanalytic as well as cognitive-behavioural long-term treatments lead to significant and sustained improvements of depressive symptoms of chronically depressed patients exceeding effect sizes of other international outcome studies.

Propaganda & Nation Building: Those exposed to government propaganda have lower salience of ethnicity, increased inter-ethnic trust & show more willingness to interact face-to-face with members of another ethnic group
Arthur Thomas Blouin and Sharun W. Mukand, "Erasing Ethnicity? Propaganda, Nation Building and Identity in Rwanda," Journal of Political Economy, https://doi.org/10.1086/701441
Abstract: This paper examines whether propaganda broadcast over radio helped to change inter-ethnic attitudes in post-genocide Rwanda. We exploit variation in exposure to the government’s radio propaganda due to the mountainous topography of Rwanda. Results of lab-in-the-field experiments show that individuals exposed to government propaganda have lower salience of ethnicity, increased inter-ethnic trust and show more willingness to interact face-to-face with members of another ethnic group. Our results suggest that the observed improvement in inter-ethnic behavior is not cosmetic, and reflects a deeper change in inter-ethnic attitudes. The findings provide some of the first quantitative evidence that the salience of ethnic identity can be manipulated by governments.

Popular derogatory terms are associated with trait Antagonism, as well as other behaviors that comprise Antagonism’s nomological network (bullying, psychopathy, etc.)
The anatomy of an insult: Popular derogatory terms connote important individual differences in Agreeableness/Antagonism. Courtland S. Hyatt, Jessica L. Maples-Keller, Chelsea E. Sleep, Donald R. Lynam, Joshua D. Miller. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2018.11.005
Highlights
• Insults are commonly used, but less is known about what they connote.
• Asshole, dick, and bitch are the most commonly used insults.
• Self-endorsement of insults is associated with trait Antagonism.
• Insult endorsement is also related to antisocial behavior (e.g,. aggression).
• Colloquial phrases appear to convey important personality-related information.
Abstract: In the current series of studies, we investigate the psychosocial connotations of common insults. In Studies 1 and 2, we investigated the most frequently used insults to denigrate men and women (asshole, dick, bitch), and generated trait profiles that can be considered prototypical of each insult. In Studies 3 and 4, we examined how these insults are relevant to other key indicators of interpersonal functioning, including aggression, social information processing, personality disorders, and substance use. We also gathered thin-slice and informant reports. Each of the insults was associated with trait Antagonism, as well as other behaviors that comprise Antagonism’s nomological network (e.g., bullying, psychopathy, etc.). Results are discussed in terms of the importance of everyday language to psychological research.

Each of the insults was associated with trait Antagonism, as well as other behaviors that comprise Antagonism’s nomological network (e.g., bullying, psychopathy, etc.). Results are discussed in terms of the importance of everyday language to psychological research.

White dreams (feeling of having had a dream experience without being able to specify this experience any further): What studying contentless dreams can teach about the neural basis of dreaming & conscious experiences
White dreams are made of colours: What studying contentless dreams can teach about the neural basis of dreaming and conscious experiences. Peter Fazekas, Georgina Nemeth, MortenOvergaard. Sleep Medicine Reviews, https://doi.org/10.1016/j.smrv.2018.10.005
Summary: Reports of white dreams, the feeling of having had a dream experience without being able to specify this experience any further, make up almost one third of all dream reports, yet this phenomenon—until very recently—had not yet been in the focus of targeted investigations. White dreams are typically interpreted as forgotten dreams, and are sidelined as not being particularly informative with regard to the nature of dreaming. In this review article, we propose a paradigm shift with respect to the status of white dreams arguing that focusing on this phenomenon can reveal fundamental insights about the neural processes that occur in the dreaming brain. As part of this paradigm shift, we propose a novel interpretation of what white dreams are. This new interpretation is made possible by recent advancements in three different though interrelated fields focusing on dreaming, mental imagery, and wakeful perception. In this paper, we bring these different threads together to show how the latest findings from these fields fit together and point towards a general framework regarding the neural underpinnings of conscious experiences that might turn out to be highly relevant not just for dream research but for all aspects of studying consciousness.

Use investigative powers to dramatize how policy rollbacks on clean air and water are hurting children’s health, leading to thousands more deaths and increased chronic pulmonary and heart disease
By all accounts, House Democrats return
to Washington this week to begin planning their priorities for 2019 in
an aggressive frame of mind. But on climate change and energy issues,
rather than simply responding to Trump’s latest provocation (like those
regarding California wildfires), they must step back and take a
strategic approach.
This means Democrats must have the discipline to subordinate all
other considerations to the key goal of creating the political and
policy conditions needed to enact landmark energy and climate
legislation after 2020, when they may well win back the White House and
Senate. Indeed, how they handle energy and climate in the next two years
will play a critical role in determining whether they gain the power to
act.Despite bright spots in Nevada and several Governors races, the mid-term elections held some cautionary lessons. The defeat in Washington State of a carbon tax referendum and several other climate-related measures in Arizona and Colorado, along with apparent state-wide losses in “ground-zero” climate impacts states of Florida and Texas, should be sobering.
The politics of climate change are complex, even for voters already suffering from its impacts. Swing voters will not respond to far-left ideological crusades or simple-minded attempts to rigidly impose “best” climate policies from above. Such approaches have largely failed as political matter for nearly 30 years now.
The good news is that winning House control allows Democrats to develop economically-framed climate change messages and policies that are powerfully in America’s self-interest and also popular with voters. Democrats must starkly contrast their cost-effective climate policies with the nihilistic and defeatist policy rollbacks of Trump Republicans, rollbacks that are putting our people, economy and security at risk.
But making climate action a popular mainstream political issue will require a strategy that integrates climate policies more coherently into broader economic, public safety and security messages and goals that the American people already share, setting the stage for policy action in 2021.
With these goals in mind, House Democrats should establish a set of basic principles to guide their approaches on climate and energy over the next two years, including:
Frame climate change as a kitchen table issue of rising economic costs, public safety and national security. Climate impacts are here and now, already costing thousands of American lives and hundreds of billions of taxpayer dollars. Stop “debating” proven climate science, and focus less on technical issues. Discuss climate change in immediate, human, local, economic, safety and security terms. More dollars and sense, fewer charts and graphs. Here and now, not about 2050.
Hold Trump accountable for policy rollbacks and the climate change impacts that are costing taxpayers billions, harming public health and worsening climate change. Focus oversight attention on the huge economic and human costs of climate impacts, including larger storms, bigger wildfires, sea-level rise, infectious disease and other impacts. Use investigative powers to dramatize how policy rollbacks on clean air and water are hurting children’s health, leading to thousands more deaths and increased chronic pulmonary and heart disease, and how freezing fuel economy is hitting drivers at the pump. Shine a spotlight on Trump’s arbitrary and capricious rollbacks of sensible regulations on super climate pollutants like methane and HFCs.
Integrate climate policy into infrastructure, tax reform, national security, and disaster-response bills, instead of standalone “climate” proposals. When climate action is included as part of overall pro-growth economic and security policies that benefit middle class and working-class Americans, it will be more popular. For example, do not pursue standalone carbon taxes legislation; such taxes should only be included as part of overall pro-growth tax reform proposals (and be voted on no earlier than 2021). Repeal the Republican tax giveaway and replacing it will tax policies that benefit the middle and working class. In other words, undertake climate action as part of pro-growth economic, job creation, infrastructure and security policy, not just environmental policy.
Don’t force Democrats to take purely symbolic but politically problematic votes. Keep your power dry. Save difficult votes for 2021 or whenever Democrats next have the actual power to make key climate legislation become law.
Invoke a can-do Democratic spirit: America can meet the energy and climate challenge and lead the world, if Democrats are in charge. Trump and Republicans are climate defeatists, who deny the very existence of climate change because they have no solutions to deal with it. Simply put, Trump and Republicans are climate wimps—the problem is just too tough for them. But not for Democrats. The party of John Kennedy’s Space Race and the Apollo Project must embrace the opportunity to create American Energy Abundance and Climate Protection together. We have the technology; now Democrats must inspire the country to provide the political will.
Most of all, create a DEMOCRATIC brand of economically-focused energy and climate action—separate and apart from national environmental groups. For too long, Democrats have ceded their climate messaging to green groups and alienated huge parts of the electorate. Embrace the full U.S. energy economy miracle that occurred under Obama, including renewable energy, efficiency, new advanced technologies and well-regulated natural gas and oil production. Use the Select Committee on Energy Independence and Climate Change to gain attention to the role of Democratic policies in creating the US remarkable clean energy economy boom, cutting US oil imports, creating millions of good new jobs, while transitioning to a much lower carbon economy.
The focus must be on creating policy measures and the political conditions that together will allow climate change to play a far larger, more advantageous role in the 2020 campaign against Trump, and that will lead to enactment of effective climate policy when Democrats win back all levers of federal power.
Just as war is too important for generals alone, climate change is far too sweeping and important an issue to be dealt with by far-left environmentalists. It is not, ultimately, even an “environmental issue” as we classically think of them. Instead, it is about protecting our safety, security, and economy, and providing ourselves and our children the more hopeful future that all Americans desire. Democrats have a chance to deliver on this promise in the near future, if they will be politically strategic, now.
Consistent Lying Decreases Belief in the Truth: Consistent false assents increased belief in those false events & consistent false denials decreased belief in those true events
Liar Liar: Consistent Lying Decreases Belief in the Truth. Danielle Polage. Applied Cognitive Psychology, accepted article, https://doi.org/10.1002/acp.3489
Summary: This study investigated the effects of lying on belief ratings for autobiographical childhood events. Participants lied by trying to convince the experimenter that likely events had not happened and that unlikely events had happened. Participants consistently lied, consistently told the truth, and alternated lying and truth telling across two sessions. Results showed that consistent false assents increased belief in those false events and that consistent false denials decreased belief in those true events. False denials had a larger influence on belief than did false assents. False assents that were told first were more likely to increase in belief than were false assents told in the second session. False denials decreased belief in the true event regardless of when they were told. These results suggest that lying influences confidence ratings both by increasing belief in a lied about event and by decreasing belief in a true event.

The discomfort regarding sex between one’s partner & robot competitors is not explained by personal characteristics (self-esteem, subjective physical attractiveness) but rather by technology-related variables (negative attitude towards robots, anthropomorphism)
Jealousy 4.0? An empirical study on jealousy-related discomfort of women evoked by other women and gynoid robots. Jessica M. Szczuka and Nicole C. Krämer. Paladyn, Journal of Behavioral Robotics, https://doi.org/10.1515/pjbr-2018-0023
Abstract: While first empirical studies on sexual aspects of human-robot interaction mostly focus on male users’ acceptance, there is no empirical research on how females react to robotic replications of women. To empirically investigate whether robots can evoke the same kind of jealousy-related discomfort as do other women, we conducted an online study in which 848 heterosexual female participants from Germany reacted to the idea that their partner had sexual intercourse with either another woman, a human-like female-looking robot, or a machine-like female-looking robot. The results revealed dimensions in which the jealousy-related discomfort was higher for female competitors compared to the robotic ones (e.g., discomfort caused by the idea of sexual intercourse), whereas in others the robots evoked the same or higher levels of jealousy-related discomfort (e.g., discomfort caused by feelings of inadequacy, discomfort caused by shared emotional and time resources). The variance in the discomfort regarding sexual interactions between one’s partner and robotic competitors could not be explained by personal characteristics (such as self-esteem, subjective physical attractiveness) but rather by technology-related variables (e.g., negative attitude towards robots, a tendency towards anthropomorphism) and the attitude towards sexual non-exclusivity in relationships. The study provides first empirical insights into a question which is of relevance for a responsible handling of sexualized technologies.

Role of relative intelligence in mate preferences: Equally intelligent partners were satisficing mates; women wanted long-term partners who were smart, men wanted short-term partners who were less smart
Is smart sexy? Examining the role of relative intelligence in mate preferences. Peter K. Jonason et al. Personality and Individual Differences, Volume 139, 1 March 2019, Pages 53-59, https://doi.org/10.1016/j.paid.2018.11.009
Highlights
• Manipulated level of relative intelligence in potential partners
• Equally intelligent partners were satisficing mates.
• Women wanted long-term partners who were smart.
• Men wanted short-term partners who were less smart.
• Women's mate value predicted preferences for intelligence.
Abstract: There has been a recent surge of research on the role of intelligence in mate preferences. To advance this area of research, in two online studies (N = 743), we manipulated relative, as opposed to absolute, intelligence and examined desirability in long-term and short-term relationships. In Study 1, we also examined the role of mate value towards understanding differences in desirability and, in Study 2, we also manipulated target's level of physical attractiveness. The sexes found less intelligent partners less desirable, a more intelligent partner was no more desirable than partner who was equal in intelligence, and intelligence was particularly valued as a long-term mate. In addition, mate value was correlated with rejecting less intelligent mates and desiring more intelligent ones in women only. And, last, we found that once men and women found sufficient rates of attractiveness for their short-term partners, they care about the intelligence of their partner.
