Revisiting the risk of automation. Melanie Arntz, Terry Gregory and Ulrich Zierahn. Economics Letters, Volume 159, October 2017, Pages 157-160, https://doi.org/10.1016/j.econlet.2017.07.001
Highlights
• Occupation-level approaches significantly overestimate automation potentials.
• Automation risk of US jobs drops from 38 to 9% when accounting for job-level tasks.
• 3 out of 4 jobs are less automatable compared to the median job of this occupation.
• Workers apparently specialize in non-automatable niches within their profession.
Abstract: In light of rapid advances in the fields of Artificial Intelligence (AI) and robotics, many scientists discuss the potentials of new technologies to substitute for human labour. Fuelling the economic debate, various empirical assessments suggest that up to half of all jobs in western industrialized countries are at risk of automation in the next 10 to 20 years. This paper demonstrates that these scenarios are overestimating the share of automatable jobs by neglecting the substantial heterogeneity of tasks within occupations as well as the adaptability of jobs in the digital transformation. To demonstrate this, we use detailed task data and show that, when taking into accounting the spectrum of tasks within occupations, the automation risk of US jobs drops, ceteris paribus, from 38 % to 9 %.

Adult sex ratios and partner scarcity among hunter–gatherers: Implications for dispersal patterns and the evolution of human sociality
Adult sex ratios and partner scarcity among hunter–gatherers: Implications for dispersal patterns and the evolution of human sociality. Karen Kramer, Ryan Schacht and Adrian Bell. Philosophical Transactions of the Royal Society: Biological Sciences, Sept 19 2017, https://doi.org/10.1098/rstb.2016.0316
Abstract: Small populations are susceptible to high genetic loads and random fluctuations in birth and death rates. While these selective forces can adversely affect their viability, small populations persist across taxa. Here, we investigate the resilience of small groups to demographic uncertainty, and specifically to fluctuations in adult sex ratio (ASR), partner availability and dispersal patterns. Using 25 years of demographic data for two Savannah Pumé groups of South American hunter–gatherers, we show that in small human populations: (i) ASRs fluctuate substantially from year to year, but do not consistently trend in a sex-biased direction; (ii) the primary driver of local variation in partner availability is stochasticity in the sex ratio at maturity; and (iii) dispersal outside of the group is an important behavioural means to mediate locally constrained mating options. To then simulate conditions under which dispersal outside of the local group may have evolved, we develop two mathematical models. Model results predict that if the ASR is biased, the globally rarer sex should disperse. The model's utility is then evaluated by applying our empirical data to this central prediction. The results are consistent with the observed hunter–gatherer pattern of variation in the sex that disperses. Together, these findings offer an alternative explanation to resource provisioning for the evolution of traits central to human sociality (e.g. flexible dispersal, bilocal post-marital residence and cooperation across local groups). We argue that in small populations, looking outside of one's local group is necessary to find a mate and that, motivated by ASR imbalance, the alliances formed to facilitate the movement of partners are an important foundation for the human-typical pattern of network formation across local groups.

Languages in Drier Climates Use Fewer Vowels
Languages in Drier Climates Use Fewer Vowels. Caleb Everett. Frontiers in Psychology, July 2017, https://doi.org/10.3389/fpsyg.2017.01285
Abstract: This study offers evidence for an environmental effect on languages while relying on continuous linguistic and continuous ecological variables. Evidence is presented for a positive association between the typical ambient humidity of a language’s native locale and that language’s degree of reliance on vowels. The vowel-usage rates of over 4000 language varieties were obtained, and several methods were employed to test whether these usage rates are associated with ambient humidity. The results of these methods are generally consistent with the notion that reduced ambient humidity eventually yields a reduced reliance of languages on vowels, when compared to consonants. The analysis controls simultaneously for linguistic phylogeny and contact between languages. The results dovetail with previous work, based on binned data, suggesting that consonantal phonemes are more common in some ecologies. In addition to being based on continuous data and a larger data sample, however, these findings are tied to experimental research suggesting that dry air affects the behavior of the larynx by yielding increased phonatory effort. The results of this study are also consistent with previous work suggesting an interaction of aridity and tonality. The data presented here suggest that languages may evolve, like the communication systems of other species, in ways that are influenced subtly by ecological factors. It is stressed that more work is required, however, to explore this association and to establish a causal relationship between ambient air characteristics and the development of languages.

Tennis grunts communicate acoustic cues to sex and contest outcome
Tennis grunts communicate acoustic cues to sex and contest outcome. Jordan Raine, Katarzyna Pisanski & David Reby. Animal Behaviour, Volume 130, August 2017, Pages 47-55, https://doi.org/10.1016/j.anbehav.2017.06.022
Abstract: Despite their ubiquity in human behaviour, the communicative functions of nonverbal vocalizations remain poorly understood. Here, we analysed the acoustic structure of tennis grunts, nonverbal vocalizations produced in a competitive context. We predicted that tennis grunts convey information about the vocalizer and context, similar to nonhuman vocal displays. Specifically, we tested whether the fundamental frequency (F0) of tennis grunts conveys static cues to a player's sex, height, weight, and age, and covaries dynamically with tennis shot type (a proxy of body posture) and the progress and outcome of male and female professional tennis contests. We also performed playback experiments (using natural and resynthesized stimuli) to assess the perceptual relevance of tennis grunts. The F0 of tennis grunts predicted player sex, but not age or body size. Serve grunts had higher F0 than forehand and backhand grunts, grunts produced later in contests had higher F0 than those produced earlier, and grunts produced during contests that players won had a lower F0 than those produced during lost contests. This difference in F0 between losses and wins emerged early in matches, and did not change in magnitude as the match progressed, suggesting a possible role of physiological and/or psychological factors manifesting early or even before matches. Playbacks revealed that listeners use grunt F0 to infer sex and contest outcome. These findings indicate that tennis grunts communicate information about both the vocalizer and contest, consistent with nonhuman mammal vocalizations.

The Perverse Effects of Subsidized Weather Insurance
Omri Ben-Shahar & Kyle D. Logue, "The Perverse Effects of Subsidized Weather Insurance," 68 Stanford Law Review 571 (2016).
Abstract. This Article explores the role of insurance as a substitute for direct regulation of risks posed by severe weather. In pricing the risk of human activity along the predicted path of storms, insurance can provide incentives for efficient location decisions as well as for cost-justified mitigation efforts in building construction and infrastructure. Currently, however, much insurance for severe-weather risks is provided and heavily subsidized by the government. This Article demonstrates two primary distortions arising from the government's dominance in these insurance markets. First, existing government subsidies are allocated differentially across households, resulting in a significant regressive redistribution favoring affluent homeowners in coastal communities. This Article provides some empirical measures of this effect. Second, existing government subsidies induce excessive development (and redevelopment) of storm-stricken and erosion-prone areas. While political efforts to scale back the insurance subsidies have so far failed, this Article contributes to a reevaluation of the social regulation of weather risk by exposing the unintended costs of government-subsidized insurance.

Correcting for Bias in Psychology: A Comparison of Meta-analytic Methods
Carter, Evan C, Felix D Schönbrodt, Will M Gervais, and Joseph Hilgard. 2017. “Correcting for Bias in Psychology: A Comparison of Meta-analytic Methods”. PsyArXiv. September 1. https://psyarxiv.com/9h3nu
Abstract: Publication bias and questionable research practices in primary research can lead to badly overestimated effects in meta-analysis. Methodologists have proposed a variety of statistical approaches to correcting for such overestimation. However, much of this work has not been tailored specifically to psychology, so it is not clear which methods work best for data typically seen in our field. Here, we present a comprehensive simulation study to examine how some of the most promising meta-analytic methods perform on data typical of psychological research. We tried to mimic realistic scenarios by simulating several levels of questionable research practices, publication bias, and heterogeneity, using study sample sizes empirically derived from the literature. Our results indicate that one method – the three-parameter selection model (Iyengar & Greenhouse, 1988; McShane, Böckenholt, & Hansen, 2016) – generally performs better than trim-and-fill, p-curve, p-uniform, PET, PEESE, or PET-PEESE, and that some of these other methods should typically not be used at all. However, it is unknown whether the success of the three-parameter selection model is due to the match between its assumptions and our modeling strategy, so future work is needed to further test its robustness. Despite this, we generally recommend that meta-analysts of data in psychology use the three-parameter selection model. Moreover, we strongly recommend that researchers in psychology continue their efforts on improving the primary literature and conducting large-scale, pre-registered replications.

Ovulatory Changes in Sexuality
Arslan, Ruben C, Katharina M Schilling, Tanja M Gerlach, and Lars Penke. 2017. “Ovulatory Changes in Sexuality”. PsyArXiv. September 4. https://psyarxiv.com/jp2ym/
Abstract: Previous research reported ovulatory changes in women’s appearance, mate preferences, extra- and in-pair sexual desire and behaviour, but has been criticised for small sample sizes, inappropriate designs, and undisclosed flexibility in analyses. In the present study, we sought to address these criticisms by preregistering our hypotheses and analysis plan and by collecting a large diary sample. We gathered over 26 thousand usable online self-reports in a diary format from 1043 women, of which 421 were naturally cycling. We inferred the fertile period from menstrual onset reports. We used hormonal contraceptive users as a quasi-control group, as they experience menstruation, but not ovulation. We probed our results for robustness to different approaches (including different fertility estimates, different exclusion criteria, adjusting for potential confounds, moderation by methodological factors). We found robust evidence supporting previously reported ovulatory increases in extra-pair desire and behaviour, in-pair desire, and self-perceived desirability, as well as no unexpected associations. Yet, we did not find predicted effects on partner mate retention behaviour, clothing choices, or narcissism. Contrary to some of the earlier literature, partners’ sexual attractiveness did not moderate the cycle shifts. Taken together, the replicability of the existing literature on ovulatory changes was mixed. We conclude with simulation-based recommendations for reading the past literature and for designing future large-scale preregistered within-subject studies to understand ovulatory cycle changes and the effects of hormonal contraception. Interindividual differences in the size of ovulatory changes emerge as an important area for further study.

Abstract: Being in a social context influences risk-taking behavior. This study aims to identify the effect of an audience’s presence on risk-taking while gambling. One hundred and thirty-two university students played a computer roulette game. They were randomly allocated to one of our three conditions: (i) either they played alone; or (ii) in the presence of the experimenter; or (iii) in the presence of the experimenter, while being videotaped. Results revealed a significant effect on risk-taking in the participants with the presence of an audience, with more risk-averse behaviors in the two types of audience conditions than in the alone condition. No differences were found between the two audience conditions. Thus, an audience may prevent risk-taking and provide a social shield.

Aggression and sleep: a daylight saving time natural experiment on the effect of mild sleep loss and gain on assaults
Aggression and sleep: a daylight saving time natural experiment on the effect of mild sleep loss and gain on assaults. Rebecca Umbach, Adrian Raine, and Greg Ridgeway. ournal of Experimental Criminology, https://link.springer.com/article/10.1007/s11292-017-9299-x
Abstract
Objectives: The purpose of this study was to test the effect of a mild, short-term sleep loss/gain on assault rates.
Methods: Using National Incidence Based Reporting System data and city-reported data from Chicago, New York, Philadelphia, and Los Angeles, we calculated the difference in assault rates on the Monday immediately following daylight saving time (DST) as compared to the Monday a week later using a Poisson quasi-maximum likelihood estimator model. The same analyses were performed to examine effects of the return to standard time in the fall. We employed several falsification checks.
Results: There were 2.9% fewer (95% CI: –4.2%, −1.6%, p < 0.0001) assaults immediately following DST, when we lose an hour, as compared to a week later. In contrast, there was a 2.8% rise in assaults immediately following the return to standard time, when an hour is gained, as compared to a week later (95% CI: 1.5%, 4.2%, p < 0.0001). Multiple falsification analyses suggest the spring findings to be robust, while the evidence to support the fall findings is weaker.
Conclusions: This study suggests that mild and short-term changes in sleep do significantly affect rates of assault. Specifically, ***there is support for the theory that mild sleepiness possibly associated with an hour loss of sleep results in reduced assaults***. This contradicts the simple inverse relationship currently suggested by most of the correlational literature. This study and the mixed findings presented by experimental studies indicate that measurement variability of both sleep and aggression may result in conflicting findings.

Emodiversity: Robust Predictor of Outcomes or Statistical Artifact?
Brown, N. J. L., & Coyne, J. C. (2017). Emodiversity: Robust Predictor of Outcomes or Statistical Artifact? Journal of Experimental Psychology. General. DOI: 10.1037/xge0000330
Abstract: This article examines the concept of emodiversity, put forward by Quoidbach et al. (2014) as a novel source of information about “the health of the human emotional ecosystem” (p. 2057). Quoidbach et al. drew an analogy between emodiversity as a desirable property of a person’s emotional make-up and biological diversity as a desirable property of an ecosystem. They claimed that emodiversity was an independent predictor of better mental and physical health outcomes in two large-scale studies. Here, we show that Quoidbach et al.’s construct of emodiversity suffers from several theoretical and practical deficiencies, which make these authors’ use of Shannon’s (1948) entropy formula to measure emodiversity highly questionable. Our reanalysis of Quoidbach et al.’s two studies shows that the apparently substantial effects that these authors reported are likely due to a failure to conduct appropriate hierarchical regression in one case, and to suppression effects in the other. It appears that Quoidbach et al.’s claims about emodiversity may reduce to little more than a set of computational and statistical artifacts.

Big Data Surveillance: The Case of Policing
Big Data Surveillance: The Case of Policing. Sarah Brayne. American Sociological Review. https://doi.org/10.1177/0003122417725865
Abstract: This article examines the intersection of two structural developments: the growth of surveillance and the rise of “big data.” Drawing on observations and interviews conducted within the Los Angeles Police Department, I offer an empirical account of how the adoption of big data analytics does—and does not—transform police surveillance practices. I argue that the adoption of big data analytics facilitates amplifications of prior surveillance practices and fundamental transformations in surveillance activities. First, discretionary assessments of risk are supplemented and quantified using risk scores. Second, data are used for predictive, rather than reactive or explanatory, purposes. Third, the proliferation of automatic alert systems makes it possible to systematically surveil an unprecedentedly large number of people. Fourth, the threshold for inclusion in law enforcement databases is lower, now including individuals who have not had direct police contact. Fifth, previously separate data systems are merged, facilitating the spread of surveillance into a wide range of institutions. Based on these findings, I develop a theoretical model of big data surveillance that can be applied to institutional domains beyond the criminal justice system. Finally, I highlight the social consequences of big data surveillance for law and social inequality.
---
For example, after a series of copper wire thefts in the city, the police found the car involved by drawing a radius in Palantir around the three places the wire was stolen from, setting up time bounds around the time they knew the thefts occurred at each site, and querying the system for any license plates captured by ALPRs in all three locations during those time periods.
[...]
I encountered several other examples of law enforcement using external data originally collected for non–criminal justice purposes, including data from repossession and collections agencies; social media, foreclosure, and electronic toll pass data; and address and usage information from utility bills. Respondents also indicated they were working on integrating hospital, pay parking lot, and university camera feeds; rebate data such as address information from contact lens rebates; and call data from pizza chains, including names, addresses, and phone numbers from Papa Johns and Pizza Hut. In some instances, it is simply easier for law enforcement to purchase privately collected data than to rely on in-house data because there are fewer constitutional protections, reporting requirements, and appellate checks on private sector surveillance and data collection (Pasquale 2014). Moreover, respondents explained, privately collected data is sometimes more up-to-date.

How quickly can we adapt to change? An assessment of hurricane damage mitigation efforts using forecast uncertainty.
How quickly can we adapt to change? An assessment of hurricane damage mitigation efforts using forecast uncertainty. By Andrew Martinez
Abstract: Our ability to adapt to extreme weather is increasingly relevant as the frequency and intensity of these events alters due to climate change. It is important to understand the effectiveness of adaptation given the uncertainty associated with future climate events. However, there has been little analysis of short-term adaptation efforts. We propose a novel approach of using errors from hurricane forecasts to evaluate short-term hurricane damage mitigation efforts. We construct a statistical model of damages for all hurricanes to strike the continental United States since 1955. While we allow for many possible drivers of damages, using model selection methods we find that a small subset explains most of the variation. We also find evidence supporting short-term adaptation effects prior to a hurricane landfall. Our results show that the 67 percent improvement in hurricane forecasts over the past 60 years is associated with damages being 16-63 percent lower than they otherwise would have been. Accounting for outlying observations narrows this range to 16-24 percent.

Sex differences in jealousy: the (Lack of) influence of researcher theoretical perspective
Sex differences in jealousy: the (Lack of) influence of researcher theoretical perspective. John Edlund et al. The Journal of Social Psycholog, http://dx.doi.org/10.1080/00224545.2017.1365686
According to the theory of evolved sex differences in jealousy (Buss, Larsen, Westen, & Semmelroth, 1992), ancestral women’s challenge of ensuring paternal investment exerted selective pressures that increased women’s jealousy in response to emotional infidelity, whereas ancestral men’s challenge of paternal uncertainty exerted selective pressures that increased men’s jealousy in response to sexual infidelity. Observing that women experience greater jealousy in response to emotional infidelity (relative to men) and that men experience greater jealousy in response to sexual infidelity (relative to women) is known as the sex differences in jealousy effect. This effect has been explored in several ways (see Edlund & Sagarin, 2017 for a comprehensive review). Most relevant to the goals of this paper are the approaches taken by Sheets and Wolfe (2001), in which participants were asked to imagine an infidelity and respond to forced-choice questions , and the approach taken by Edlund, Heider, Scherer, Farc, and Sagarin (2006), in which participants were asked to respond on continuous items .
However, this sex difference in jealousy effect has not been without significant controversy in the literature. For instance, DeSteno and colleagues (DeSteno, Bartlett, Bravermann, & Salovey, 2002) have suggested that men and women had differential interpretations of the forced-choice questions (called the “double-shot” hypothesis); however, Buss and colleagues (Buss et al., 1999) later demonstrated that the double-shot hypothesis cannot explain the relationship between participant sex and jealousy. Harris (2002) questioned whether sex differences in cognitive focus (not emotional jealousy) in response to actual experiences with infidelity mirrored hypothetical reactions and whether the effect in the hypothetical reaction literature was an artifact of the forced-choice measure. Edlund and colleagues (Edlund et al., 2006) later demonstrated that sex differences in jealousy in response to actual experiences with infidelity mirrored hypothetical reactions in both forced-choice and continuous measures. Importantly, meta-analyses have confirmed that this effect reliably emerges with both forced-choice (Harris, 2002) and continuous measures of jealousy (Sagarin et al., 2012). One significant point of contention in the literature, and the one addressed in the current study, is whether successfully observing a sex difference in jealousy effect is driven by the theoretical perspective of the researchers. Many of the studies attempting to refute the theory of evolved sex differences in jealousy have been published in general psychological journals (e.g., Psychological Science) and in social psychology journals (e.g., Personality and Social Psychology Bulletin). Conversely, many of the studies supporting the sex difference in jealousy have been published in journals oriented toward evolutionary psychology (e.g., Evolutionary Psychology). This discrepancy is highlighted by Edlund and Sagarin (2017), who demonstrate the differences in the publication outlets, but they do not offer evidence as to whether the theoretical perspective of the researchers is the driving factor in the eventual publication outlets.
Given the disparate nature of the researchers on both sides of the debate and the resultant diversity in the outlets in which their findings have been published, one of the goals of the present research was to bring diverse researchers together (many of whom have never published with one another) to investigate whether theoretical perspective impacted the sex difference in jealousy. We also sought to provide another replication of the sex difference in jealousy effect while examining both continuous and forced-choice measures. Finally, we sought to extend the sex difference in jealousy literature by incorporating an individual difference measure – a self-perceived measure of how high quality a mate one is (i.e., mate value) – as a potential moderator of the sex difference in jealousy effect. For instance, research has shown that mate value moderates one’s preferences in a mate (e.g., Edlund & Sagarin, 2010; Reeve, Kelly, & Welling, 2017), as well as one’s intention to commit an infidelity (Starratt, Weekes-Shackelford, & Shackelford, 2017). As such, given mate value’s impact on intentions towards infidelity, we wanted to explore if it would similarly impact the reactions to an infidelity.
[...]
In summary, we have demonstrated that the sex difference in jealousy occurs in both forcedchoice and continuous response scale formats. We also demonstrated that the theoretical perspective of the researchers has no bearing on the results obtained when using identical tools. Finally, we have demonstrated that mate value moderates the sex difference in jealousy.
According to the theory of evolved sex differences in jealousy (Buss, Larsen, Westen, & Semmelroth, 1992), ancestral women’s challenge of ensuring paternal investment exerted selective pressures that increased women’s jealousy in response to emotional infidelity, whereas ancestral men’s challenge of paternal uncertainty exerted selective pressures that increased men’s jealousy in response to sexual infidelity. Observing that women experience greater jealousy in response to emotional infidelity (relative to men) and that men experience greater jealousy in response to sexual infidelity (relative to women) is known as the sex differences in jealousy effect. This effect has been explored in several ways (see Edlund & Sagarin, 2017 for a comprehensive review). Most relevant to the goals of this paper are the approaches taken by Sheets and Wolfe (2001), in which participants were asked to imagine an infidelity and respond to forced-choice questions , and the approach taken by Edlund, Heider, Scherer, Farc, and Sagarin (2006), in which participants were asked to respond on continuous items .

A good rule of thumb is that you will want to read any working paper Melissa Dell puts out. Her main interest is the long-run path-dependent effect of historical institutions, with rigorous quantitative investigation of the subtle conditionality of the past. For instance, in her earlier work on Peru (Econometrica, 2010), mine slavery in the colonial era led to fewer hacienda style plantations at the end of the era, which led to less political power without those large landholders in the early democratic era, which led to fewer public goods throughout the 20th century, which led to less education and income today in eras that used to have mine slavery. One way to read this is that local inequality is the past may, through political institutions, be a good thing today! History is not as simple as “inequality is the past causes bad outcomes today” or “extractive institutions in the past cause bad outcomes today” or “colonial economic distortions cause bad outcomes today”. [...]
Dell’s new paper looks at the cultuurstelsel, a policy the Dutch imposed on Java in the mid-19th century. Essentially, the Netherlands was broke and Java was suitable for sugar, so the Dutch required villages in certain regions to use huge portions of their arable land, and labor effort, to produce sugar for export. They built roads and some rail, as well as sugar factories (now generally long gone), as part of this effort, and the land used for sugar production generally became public village land controlled at the behest of local leaders. This was back in the mid-1800s, so surely it shouldn’t affect anything of substance today?
But it did! Take a look at villages near the old sugar plantations, or that were forced to plant sugar, and you’ll find higher incomes, higher education levels, high school attendance rates even back in the late colonial era, higher population densities, and more workers today in retail and manufacturing. Dell and Olken did some wild data matching using a great database of geographic names collected by the US government to match the historic villages where these sugar plants, and these labor requirements, were located with modern village and town locations. They then constructed “placebo” factories – locations along coastal rivers in sugar growing regions with appropriate topography where a plant could have been located but wasn’t. In particular, as in the famous Salop circle, you won’t locate a factory too close to an existing one, but there are many counterfactual equilibria where we just shift all the factories one way or the other. By comparing the predicted effect of distance from the real factory on outcomes today with the predicted effect of distance from the huge number of hypothetical factories, you can isolate the historic local influence of the real factory from other local features which can’t be controlled for.
Consumption right next to old, long-destroyed factories is 14% higher than even five kilometers away, education is 1.25 years longer on average, electrification, road, and rail density are all substantially higher, and industrial production upstream and downstream from sugar (e.g., farm machinery upstream, and processed foods downstream) are also much more likely to be located in villages with historic factories even if there is no sugar production anymore in that region!
It’s not just the factory and Dutch investments that matter, however. Consider the villages, up to 10 kilometers away, which were forced to grow the raw cane. Their elites took private land for this purpose, and land inequality remains higher in villages that were forced to grow cane compared to villages right next door that were outside the Dutch-imposed boundary. But this public land permitted surplus extraction in an agricultural society which could be used for public goods, like schooling, which would later become important! These villages were much more likely to have schools especially before the 1970s, when public schooling in Indonesia was limited, and today are higher density, richer, more educated, and less agricultural than villages nearby which weren’t forced to grow cane. This all has shades of the long debate on “forward linkages” in agricultural societies, where it is hypothesized that agricultural surplus benefits industrialization by providing the surplus necessary for education and capital to be purchased; [...].
Are you surprised by these results? [me: NO!] They fascinate me, honestly. Think through the logic: forced labor (in the surrounding villages) and extractive capital (rail and factories built solely to export a crop in little use domestically) both have positive long-run local effects! They do so by affecting institutions – whether villages have the ability to produce public goods like education – and by affecting incentives – the production of capital used up- and downstream. One can easily imagine cases where forced labor and extractive capital have negative long-run effects, and we have great papers by Daron Acemoglu, Nathan Nunn, Sara Lowes and others on precisely this point. But it is also very easy for societies to get trapped in bad path dependent equilibria, for which outside intervention, even ethically shameful ones, can (perhaps inadvertently) cause useful shifts in incentives and institutions! I recall a visit to Babeldaob, the main island in Palau. During the Japanese colonial period, the island was heavily industrialized as part of Japan’s war machine. These factories were destroyed by the Allies in World War 2. Yet despite their extractive history, a local told me many on the island believe that the industrial development of the region was permanently harmed when those factories were damaged. [...]
2017 Working Paper is here [https://scholar.harvard.edu/files/dell/files/170414draft.pdf] (no RePEc IDEAS version). For more on sugar and institutions, I highly recommend Christian Dippel, Avner Greif and Dan Trefler’s recent paper on Caribbean sugar. The price of sugar fell enormously in the late 19th century, yet wages on islands which lost the ability to productively export sugar rose. Why? Planters in places like Barbados had so much money from their sugar exports that they could manipulate local governance and the police, while planters in places like the Virgin Islands became too poor to do the same. This decreased labor coercion, permitting workers on sugar plantations to work small plots or move to other industries, raising wages in the end. [...].

Much ado about grit: A meta-analytic synthesis of the grit literature
Credé, M., Tynan, M. C., & Harms, P. D. (2017). Much ado about grit: A meta-analytic synthesis of the grit literature. Journal of Personality and Social Psychology, 113(3), 492-511.
http://dx.doi.org/10.1037/pspp0000102
Abstract: Grit has been presented as a higher order personality trait that is highly predictive of both success and performance and distinct from other traits such as conscientiousness. This paper provides a meta-analytic review of the grit literature with a particular focus on the structure of grit and the relation between grit and performance, retention, conscientiousness, cognitive ability, and demographic variables. Our results based on 584 effect sizes from 88 independent samples representing 66,807 individuals indicate that the higher order structure of grit is not confirmed, that grit is only moderately correlated with performance and retention, and that grit is very strongly correlated with conscientiousness. We also find that the perseverance of effort facet has significantly stronger criterion validities than the consistency of interest facet and that perseverance of effort explains variance in academic performance even after controlling for conscientiousness. In aggregate our results suggest that interventions designed to enhance grit may only have weak effects on performance and success, that the construct validity of grit is in question, and that the primary utility of the grit construct may lie in the perseverance facet.

Kahan, Dan M. and Peters, Ellen, Rumors of the 'Nonreplication' of the 'Motivated Numeracy Effect' are Greatly Exaggerated (August 26, 2017). Available at SSRN: https://ssrn.com/abstract=3026941
Abstract: This paper does three things. First, it describes the design defects (principally, the lack of statistical power) that make it misleading for Ballarini & Sloman (2017) to claim that they “failed to replicate” the results of Kahan, Peters et al. (2017). Second, it presents the positive results of our own replication study. Finally, we conclude with a brief discussion of why confining assertions of non-replication to studies that satisfy emerging replication protocols—in particular the imperative of “faithful recreation of a study with high statistical power” (Brandt, Ijzerman et al 2014, p. 217)—is essential to the contribution such studies can make as building blocks of a cumulative science.
---
The authors ask a neutral problem (if a skin cream works well or not for some rash), and a politicized question (is a change in gun laws associated to more or to less crime?) in a form called covariance detection task (they present fictional studies with fictional results and ask the subjects whether the study supports one answer or the other). They do not ask subjects what they think of the real world, just if the study supports or not an answer or the other... But the subjects cannot be neutral. The authors add:
This “covariance detection” task is hard. Consistent with existing literature, ***only 30%*** of the MN sample overall supplied the correct answer in the “skin rash” group. Skin-rash group participants who scored in the 95th percentile of numeracy, in contrast, tended to get the correct answer in the “skin rash” treatment group ***around 75%*** of the time.
The high-numeracy participants in that group also tended to identify the correct solution—but only when that solution affirmed the position associated with their political identity (crime increases for “Liberal Democrat” vs. crime decreases for “Conservative Republican”). When the correct answer disconfirmed (or “threatened”) the position associated with their political identity (crime increased for Liberal Democrat and crime decreased for Conservative Republican), the high-numeracy participants performed no better than the low- and moderately-numerate participants who shared their identity (Kahan, Peters, et al., 2017).
This result is not consistent with the widespread assumption that political and cultural conflict over scientific data is rooted in the prevalence of System-1 thinking in the general population. It is more consistent with an alternative view that sees numeracy and other forms of System-2 reasoning as re-sources that can be used in the service of identity-protective cognition, a form of motivated information processing that aims to maintain correspondence between an individual’s factual beliefs and the factual beliefs known to be markers of membership in, and loyalty to, one’s cultural group (Bolsen et al. 2014; Kahan 2013, 2009; Sherman & Cohen 2006).

Facial Width-to-height Ratio Does Not Predict Self-reported Behavioral Tendencies
Kosinski, Michal. 2017. “Facial Width-to-height Ratio Does Not Predict Self-reported Behavioral Tendencies”. PsyArXiv. September 2. doi:10.1177/0956797617716929.
Abstract: A growing number of studies have linked facial width-to-height ratio (fWHR) with various antisocial or violent behavioral tendencies. However, those studies have predominantly been laboratory based and low powered. This work reexamined the links between fWHR and behavioral tendencies in a large sample of 137,163 participants. Behavioral tendencies were measured using 55 well-established psychometric scales, including self-report scales measuring intelligence, domains and facets of the five-factor model of personality, impulsiveness, sense of fairness, sensational interests, self-monitoring, impression management, and satisfaction with life. The findings revealed that fWHR is not substantially linked with any of these self-reported measures of behavioral tendencies, calling into question whether the links between fWHR and behavior generalize beyond the small samples and specific experimental settings that have been used in past fWHR research.

Contrary to the hypothesis, predicted pleasure eating sweets was significantly lower than observed pleasure
Fallon, Matthew D., "The Role of Affective Forecasting and the Impact Bias in Nutritional Health Behaviors" (2017). Grand Valley State University, Masters Theses. 854. http://scholarworks.gvsu.edu/theses/854
Abstract: Previous literature on affective forecasting has studied its role in health decisions, but there is little research investigating affective forecasting in diet choices and eating behaviors. The present study collected affective forecasts from 43 college participants before eating an indulgent snack and then observed emotions immediately after eating the snack. We predicted that emotion predictions would be significantly stronger than observed emotions, in support of previous literature on the impact bias. We also predicted that optimism would predict a stronger impact bias and that extraversion and neuroticism would have a role in forecasts and observed emotions. Contrary to our hypothesis, predicted pleasure (M=2.12) was significantly lower than observed pleasure (M=2.34), F(1,42)=5.44, p=.025. Likewise, for participants who ate M&Ms rather than cookies or chips, participants had significantly higher observed positive emotion (M=1.95) than they had predicted (1.73), F(1,14)=5.78, p=.031. Trait optimism had significant interaction effects for positive affect, for each food chosen, such that as optimism increases, predicted affect increased more rapidly than observed affect. Neuroticism and extraversion were found to significantly influence predicted and observed positive affect, but had no effect on the accuracy of the affective forecasts. The present findings did not indicate the presence of an impact bias, but support previous affective forecasting literature in other aspects. These findings indicate that many of the phenomena in affective forecasting influence food forecasts. This holds implications for future research on affective forecasting in food choice and interventions targeting forecasting errors to improve diet.

We also predicted that optimism would predict a stronger impact bias and that extraversion and neuroticism would have a role in forecasts and observed emotions. Contrary to our hypothesis, predicted pleasure (M=2.12) was significantly lower than observed pleasure (M=2.34), F(1,42)=5.44, p=.025. Likewise, for participants who ate M&Ms rather than cookies or chips, participants had significantly higher observed positive emotion (M=1.95) than they had predicted (1.73), F(1,14)=5.78, p=.031. Trait optimism had significant interaction effects for positive affect, for each food chosen, such that as optimism increases, predicted affect increased more rapidly than observed affect. Neuroticism and extraversion were found to significantly influence predicted and observed positive affect, but had no effect on the accuracy of the affective forecasts. The present findings did not indicate the presence of an impact bias, but support previous affective forecasting literature in other aspects. These findings indicate that many of the phenomena in affective forecasting influence food forecasts. This holds implications for future research on affective forecasting in food choice and interventions targeting forecasting errors to improve diet.

The estimated 79% heritability of schizophrenia is congruent with previous reports and indicates a substantial genetic risk
Heritability of schizophrenia and schizophrenia spectrum based on the nationwide Danish Twin Register. Rikke Hilker, MD, PhD. Biological Psychiatry. https://doi.org/10.1016/j.biopsych.2017.08.017
Abstract
Background: Twin studies have provided evidence that both genetic and environmental factors contribute to schizophrenia risk. Heritability estimates of schizophrenia in twin samples have varied methodologically. This study provides updated heritability estimates based on nationwide twin data and an improved statistical methodology.
Method: Combining two nationwide registers, the Danish Twin Register and the Danish Psychiatric Research Register, we identified a sample of twins born 1951-2000 (N=31,524 twin pairs). Twins were followed up until June 1st 2011. Liability threshold models adjusting for censoring with inverse probability weighting were used to estimate probandwise concordance rates and heritability of the diagnoses of schizophrenia and schizophrenia spectrum disorders.
Results: The probandwise concordance rate of schizophrenia is 33% in monozygotic (MZ) twins and 7% in dizygotic (DZ) twins. We estimated the heritability of schizophrenia to be 79%. When expanding illness outcome to include schizophrenia spectrum disorders, the heritability estimate was almost similar, 73%.
Conclusion: The key strength of this study is the application of a novel statistical method accounting for censoring in the follow-up period to a nationwide twin sample. The estimated 79% heritability of schizophrenia is congruent with previous reports and indicates a substantial genetic risk. The high genetic risk also applies to a broader phenotype of schizophrenia spectrum disorders. The low concordance rate of 33% in MZ twins demonstrates that illness vulnerability is not solely indicated by genetic factors.

Superior Pattern Detectors Efficiently Learn, Activate, Apply, and Update Social Stereotypes
Superior Pattern Detectors Efficiently Learn, Activate, Apply, and Update Social Stereotypes. David Lick, Adam Alter and Jonathan Freeman. Journal of Experimental Psychology: General, https://doi.org/10.1037/xge0000349
Abstract: Superior cognitive abilities are generally associated with positive outcomes such as academic achievement and social mobility. Here, we explore the darker side of cognitive ability, highlighting robust links between pattern detection and stereotyping. Across 6 studies, we find that superior pattern detectors efficiently learn and use stereotypes about social groups. This pattern holds across explicit (Studies 1 and 2), implicit (Studies 2 and 4), and behavioral measures of stereotyping (Study 3). We also find that superior pattern detectors readily update their stereotypes when confronted with new information (Study 5), making them particularly susceptible to counterstereotype training (Study 6). Pattern detection skills therefore equip people to act as naïve empiricists who calibrate their stereotypes to match incoming information. These findings highlight novel effects of individual aptitudes on social–cognitive processes.

Group identity as a source of threat and means of compensation: Establishing personal control through group identification and ideology
Goode, C., Keefer, L. A., Branscombe, N. R., and Molina, L. E. (2017) Group identity as a source of threat and means of compensation: Establishing personal control through group identification and ideology. Eur. J. Soc. Psychol., 47: 259–272. doi: 10.1002/ejsp.2259.
Abstract: Compensatory control theory proposes that individuals can assuage threatened personal control by endorsing external systems or agents that provide a sense that the world is meaningfully ordered. Recent research drawing on this perspective finds that one means by which individuals can compensate for a loss of control is adherence to ideological beliefs about the social world. This prior work, however, has largely neglected the role of social groups in defining either the nature of control threat or the means by which individuals compensate for these threats. In four experiments (N = 466), we test the possibility that group-based threats to personal control can be effectively managed by defensively identifying with the threatened group and its values. We provide evidence for the specificity of these effects by demonstrating that defensive identification and ideology endorsement are specific to the content of the group-based threat.

Hispanics choose vehicles that are about 5-8% more expensive
Visible Consumption and Race: Evidence from Auto-Loans. Konstantinos Tzioumis. U.S. Department of the Treasury Working Paper, July 2017.
Abstract: This paper uses auto-loan applications to assess differences in consumption preferences across races. After controlling for income and age, Whites and Blacks are found to have similar choices in terms of vehicle value, while Hispanics choose vehicles that are about 5-8% more expensive. These results add to the literature by drawing on documented choices rather than realized purchases.

Similarities in smell and taste preferences in couples increase with relationship duration
Similarities in smell and taste preferences in couples increase with relationship duration. Agata Groyecka et al. Appetite, https://doi.org/10.1016/j.appet.2017.08.035
Abstract: Numerous studies point to partners’ congruence in various domains and note an increase in their compatibility over time. However, none have explored a shift in chemosensory perception related to relationship duration. Here, we examined the relationship between the time heterosexual couples have spent together and the degree to which they share their gustatory and olfactory preferences. Additionally, we investigated whether these preferences are associated with relationship satisfaction. One-hundred couples aged from 18 to 68 years being together for a period between 3 and 540 months rated the pleasantness of a wide variety of olfactory and gustatory stimuli. We showed that both taste and smell preferences are more similar the longer couples have been in a relationship. We also observed a very interesting trend in terms of smell preferences, with relationship satisfaction being negatively related to congruence in smell preferences between partners. We discuss these results from the perspective of evolutionary psychology.

Bias and ignorance in demographic perception -- part of a very general pattern of human psychology
Bias and ignorance in demographic perception. D. Landy, B. Guay and T. Marghetis. Psychonomic Bulletin & Review, https://link.springer.com/article/10.3758/s13423-017-1360-2
Abstract: When it comes to knowledge of demographic facts, misinformation appears to be the norm. Americans massively overestimate the proportions of their fellow citizens who are immigrants, Muslim, LGBTQ, and Latino, but underestimate those who are White or Christian. Previous explanations of these estimation errors have invoked topic-specific mechanisms such as xenophobia or media bias. We reconsidered this pattern of errors in the light of more than 30 years of research on the psychological processes involved in proportion estimation and decision-making under uncertainty. In two publicly available datasets featuring demographic estimates from 14 countries, we found that proportion estimates of national demographics correspond closely to what is found in laboratory studies of quantitative estimates more generally. Biases in demographic estimation, therefore, are part of a very general pattern of human psychology—independent of the particular topic or demographic under consideration—that explains most of the error in estimates of the size of politically salient populations. By situating demographic estimates within a broader understanding of general quantity estimation, these results demand reevaluation of both topic-specific misinformation about demographic facts and topic-specific explanations of demographic ignorance, such as media bias and xenophobia.

Visually conspicuous vehicle modifications influence perceptions of male owner's reproductive strategy and attractiveness
Visually conspicuous vehicle modifications influence perceptions of male owner's reproductive strategy and attractiveness. Daniel J. Kruger and Jessica S. Kruger. EvoS Journal: The Journal of the Evolutionary Studies Consortium. 2016, NEEPS Special Issue pp. 1-12. http://www-personal.umich.edu/~kruger/Krugers_Rims_Evos_2016.pdf
ABSTRACT: Resource displays are an important aspect of male mating effort. Males with relatively higher mating effort may invest proportionally more in economic display at the expense of savings and paternal investment. We predicted that aftermarket motor vehicle modifications would influence perceptions of male vehicle owners. Male owners of vehicles with upgraded wheels, compared to owners of vehicles with stock wheels, would be rated 1a) higher on mating effort, 1b) lower on parental investment, 2a) higher in interest for brief sexual affairs, 2b) lower in interest for long-term committed romantic relationships, 3a) higher in attractiveness to women for brief sexual affairs, and 3b) lower in attractiveness to women for long-term committed romantic relationships. We used before and after modification images of a Jeep Rubicon and Chrysler 300. Results for ratings of Jeep owners supported all hypotheses, but only for male participants. Results for ratings of Chrysler 300 owners supported hypotheses regarding life history dimensions (1a and 1b) and attractiveness to women (3a and 3b) for all participants. Results for ratings of Chrysler 300 owners' relationship interest (2a and 2b) fit the predicted pattern for the upgraded vehicle, but not in comparisons with the stock vehicle.

Openness to Experience and Conscientiousness are consistent predictors of authoritarian tendencies
The Prejudiced Personality? Using the Big Five to Predict Susceptibility to Stereotyping Behavior. Philip Chen and Carl Palmer. American Politics Research, https://doi.org/10.1177/1532673X17719720
Abstract: Although long privileged by scholarship in psychology, personality has only recently been considered as an influential factor for political orientations and actions. In this article, we consider personality’s influence on another important tendency: the proclivity to engage in stereotyping and prejudicial thinking. Using a personality battery included for the first time on the 2012 American National Election Study (ANES), we examine the tendencies of particular personality types to stereotype. Results suggest that the two most politically relevant traits (Openness to Experience and Conscientiousness) are consistent predictors of authoritarian tendencies, which, in turn, produce indirect effects of personality on group-centric policy positions, over and above the effects through political predispositions such as partisanship. Our findings demonstrate the important role of group stereotyping in mediating the effects of personality on policy support.

Keeping Minorities Happy: Hierarchy Maintenance and Whites’ Decreased Support for Highly Identified White Politicians
Keeping Minorities Happy: Hierarchy Maintenance and Whites’ Decreased Support for Highly Identified White Politicians. Sora Jun, Brian Lowery and Lucia Guillory. Personality and Social Psychology Bulletin, http://journals.sagepub.com/doi/abs/10.1177/0146167217722554?journalCode=pspc
Abstract: We test the hypothesis that, to avoid provoking minorities, Whites will withhold their support for White political candidates who are highly identified with their race. In Study 1, we found that White Republicans were less supportive of White candidates the higher the perceived White identity of the candidate due to beliefs that such candidates would provoke racial minorities. In Study 2, we replicated this effect with a manipulation of candidates’ White identity. Study 3 found that Whites reported less support for high-identity candidates when they were led to believe that the hierarchy was unstable rather than stable. Consistent with our hypothesis that those who have the most to lose are most likely to avoid provoking minorities, in Study 4, we found that Whites with high subjective socioeconomic status (SES) varied their support for provocative White candidates as a function of hierarchy stability, whereas those with low subjective SES did not.

The Evil Eye: Eye Gaze and Competitiveness in Social Decision Making
Giacomantonio, M., Jordan, J., Federico, F., van den Assem, M. J., and van Dolder, D. (2017) The Evil Eye: Eye Gaze and Competitiveness in Social Decision Making. Eur. J. Soc. Psychol., http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2336/full
Abstract: We demonstrate that a person's eye gaze and his/her competitiveness are closely intertwined in social decision making. In an exploratory examination of this relationship, Study 1 uses field data from a high-stakes TV game show to demonstrate that the frequency by which contestants gaze at their opponent's eyes predicts their defection in a variant on the prisoner's dilemma. Studies 2 and 3 use experiments to examine the underlying causality and demonstrate that the relationship between gazing and competitive behavior is bi-directional. In Study 2, fixation on the eyes, compared to the face, increases competitive behavior toward the target in an ultimatum game. In Study 3, we manipulate the framing of a negotiation (cooperative vs. competitive) and use an eye tracker to measure fixation number and time spent fixating on the counterpart's eyes. We find that a competitive negotiation elicits more gazing, which in turn leads to more competitive behavior.

Adding Insult to Injury: Sex, Sexual Orientation, and Juror Decision Making in a Case of Intimate Partner Violence
Adding Insult to Injury: Sex, Sexual Orientation, and Juror Decision Making in a Case of Intimate Partner Violence. Marissa Stanziani, Jennifer Cox and C. Adam Coffey. Journal of Homosexuality, http://dx.doi.org/10.1080/00918369.2017.1374066
ABSTRACT: Societal definitions of intimate partner violence (IPV) are highly gendered and heteronormative, resulting in dissonance regarding cases of same-sex IPV. This study explored perceptions of IPV when the context of the case is inconsistent with societal norms regarding sex and sexuality. Mock jurors read a vignette describing a case of alleged IPV in which the sex and sexual orientation of the defendant were manipulated. Participants (N = 415) rendered a verdict and provided ratings of the defendant, victim, and case. Results suggest participants were more confident in a guilty verdict when the defendant was male, compared to female. Further, male defendants were perceived as more morally responsible, but only when the victim was female. Perceptions regarding the crime suggest violence perpetrated by a man against a woman is viewed more adversely than any other condition. Data are discussed in terms of implications for legal decision makers and public policy.

Gender differences in SCRABBLE performance and associated engagement in purposeful practice activities
Gender differences in SCRABBLE performance and associated engagement in purposeful practice activities. Jerad H. Moxley, K. Anders Ericsson and Michael Tuffiash. Psychological Research. https://link.springer.com/article/10.1007/s00426-017-0905-3
Abstract: In two studies, the SCRABBLE skill of male and female participants at the National SCRABBLE Championship was analyzed and revealed superior performance for males. By collecting increasingly detailed information about the participants’ engagement in practice-related activities, we found that over half of the variance in SCRABBLE performance was accounted for by measures of starting ages and the amount of different types of practice activities. Males and females did not differ significantly in the benefits to their performance derived from engagement in SCRABBLE-specific practice alone (purposeful practice). However, gender differences in performance were fully mediated by lower engagement in purposeful practice by females and by their rated preference for playing games of SCRABBLE—an activity where more extended engagement is not associated with increased SCRABBLE performance. General implications from our account of gender differences in skill acquisition are discussed, and future research is proposed for how the duration of engagement in effective deliberate practice can be experimentally manipulated.

Is Doing Your Homework Associated with Becoming More Conscientiousness?
Is Doing Your Homework Associated with Becoming More Conscientiousness? Richard Göllner et al. Journal of Research in Personality. https://doi.org/10.1016/j.jrp.2017.08.007
Highlights
• More effort in students’ homework is associated with a more positive development in conscientiousness.
• Effects remain stable after controlling for differences between students increasing and decreasing their homework effort.
• Associations are found for self-reported and parent-reported personality.
Abstract: Research has shown that sustained homework effort enhances academic performance and that students’ conscientiousness is a powerful predictor of students’ homework effort. But does homework—as homework proponents claim—in turn also influence the development of conscientiousness over time? In the present study, we examined whether students’ homework effort in two subjects (i.e., mathematics and language) was associated with inter-individual differences in students’ development of conscientiousness in the early years of adolescence. Bivariate change models with a total of N = 2,760 students revealed that homework effort and conscientiousness were systematically related over time (Grade 5 to Grade 8). Most importantly, students who invested more effort in their homework showed more positive development in conscientiousness.

Conservatism predicts lapses from vegetarian/vegan diets to meat consumption (through lower social justice concerns and social support)
Conservatism predicts lapses from vegetarian/vegan diets to meat consumption (through lower social justice concerns and social support). Gordon Hodson and Earle Megan. Appetite. https://doi.org/10.1016/j.appet.2017.08.027
Abstract: Lapses from vegetarian and vegan (i.e., veg*n) food choices to meat consumption are very common, suggesting that sustaining veg*nism is challenging. But little is known about why people return to eating animals after initially deciding to avoid meat consumption. Several potential explanatory factors include personal inconvenience, meat cravings, awkwardness in social settings, or health/nutrition concerns. Here we test the degree to which political ideology predicts lapsing to meat consumption. Past research demonstrates that political ideology predicts present levels of meat consumption, whereby those higher in right-wing ideologies eat more animals, even after controlling for their hedonistic liking of meat (e.g., Dhont & Hodson, 2014). To what extent might political ideology predict whether one has lapsed from veg*n foods back to meat consumption? In a largely representative US community sample (N = 1313) of current and former veg*ns, those higher (vs. lower) in conservatism exhibited significantly greater odds of being a former than current veg*n, even after controlling for age, education, and gender. This ideology-lapsing relation was mediated (i.e., explained) by those higher (vs. lower) in conservatism: (a) adopting a veg*n diet for reasons less centered in justice concerns (animal rights, environment, feeding the poor); and (b) feeling socially unsupported in their endeavor. In contrast, factors such as differential meat craving or lifestyle inconvenience played little mediational role. These findings demonstrate that ideology and justice concerns are particularly relevant to understanding resilience in maintaining veg*n food choices. Implications for understanding why people eat meat, and how to develop intervention strategies, are discussed.

No mutual mate choice for quality in zebra finches: Time to question a widely-held assumption
Wang, D., Forstmeier, W. and Kempenaers, B. (), No mutual mate choice for quality in zebra finches: Time to question a widely-held assumption. Evolution. Accepted Author Manuscript.
https://doi.org/10.1111/evo.13341
Abstract: Studies of mate choice typically assume that individuals prefer high quality mates and select them based on condition-dependent indicator traits. In species with bi-parental care, mutual mate choice is expected to result in assortative mating for quality. When assortment is not perfect, the lower quality pair members are expected to compensate by increased parental investment to secure their partner (positive differential allocation). This framework has been assumed to hold for monogamous species like the zebra finch (Taeniopygia guttata), but progress has been hampered by the difficulty to define individual quality. By combining multiple measures of causes (inbreeding, early nutrition) and consequences (ornaments, displays, fitness components) of variation in quality into a single principal component, we here show that quality variation can be quantified successfully. We further show that variation in quality indeed predicts individual pairing success, presumably because it reflects an individual's vigor or ability to invest in reproduction. However, despite high statistical power, we found no evidence for either assortative mating or for positive differential allocation. We suggest that zebra finch ornaments and displays are not sufficiently reliable for the benefits of choosiness to exceed the costs of competition for the putative best partner. To assess the generality of these findings unbiased quantification of signal honesty and preference strength is required, rather than selective reporting of significant results.

Abstract: Studies of mate choice typically assume that individuals prefer high quality mates and select them based on condition-dependent indicator traits. In species with bi-parental care, mutual mate choice is expected to result in assortative mating for quality. When assortment is not perfect, the lower quality pair members are expected to compensate by increased parental investment to secure their partner (positive differential allocation). This framework has been assumed to hold for monogamous species like the zebra finch (Taeniopygia guttata), but progress has been hampered by the difficulty to define individual quality. By combining multiple measures of causes (inbreeding, early nutrition) and consequences (ornaments, displays, fitness components) of variation in quality into a single principal component, we here show that quality variation can be quantified successfully. We further show that variation in quality indeed predicts individual pairing success, presumably because it reflects an individual's vigor or ability to invest in reproduction. However, despite high statistical power, we found no evidence for either assortative mating or for positive differential allocation. We suggest that zebra finch ornaments and displays are not sufficiently reliable for the benefits of choosiness to exceed the costs of competition for the putative best partner. To assess the generality of these findings unbiased quantification of signal honesty and preference strength is required, rather than selective reporting of significant results.
The strategic moral self: Self-presentation shapes moral dilemma judgments
The strategic moral self: Self-presentation shapes moral dilemma judgments. Sarah C. Rom and Paul Conway. Journal of Experimental Social Psychology, Volume 74, January 2018, Pages 24–37
https://doi.org/10.1016/j.jesp.2017.08.003
Abstract: Research has focused on the cognitive and affective processes underpinning dilemma judgments where causing harm maximizes outcomes. Yet, recent work indicates that lay perceivers infer the processes behind others' judgments, raising two new questions: whether decision-makers accurately anticipate the inferences perceivers draw from their judgments (i.e., meta-insight), and, whether decision-makers strategically modify judgments to present themselves favorably. Across seven studies, ***a) people correctly anticipated how their dilemma judgments would influence perceivers' ratings of their warmth and competence, though self-ratings differed (Studies 1–3), b) people strategically shifted public (but not private) dilemma judgments to present themselves as warm or competent depending on which traits the situation favored (Studies 4–6), and, c) self-presentation strategies augmented perceptions of the weaker trait implied by their judgment*** (Study 7). These results suggest that moral dilemma judgments arise out of more than just basic cognitive and affective processes; complex social considerations causally contribute to dilemma decision-making.

Truth or Punishment: Secrecy and Punishing the Self
Truth or Punishment: Secrecy and Punishing the Self. Michael Slepian and Brock Bastian. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167217717245
Abstract: We live in a world that values justice; when a crime is committed, just punishment is expected to follow. Keeping one's misdeed secret therefore appears to be a strategic way to avoid (just) consequences. Yet, people may engage in self-punishment to right their own wrongs to balance their personal sense of justice. Thus, those who seek an escape from justice by keeping secrets may in fact end up serving that same justice on themselves (through self-punishment). Six studies demonstrate that thinking about secret (vs. confessed) misdeeds leads to increased self-punishment (increased denial of pleasure and seeking of pain). These effects were mediated by the feeling one deserved to be punished, moderated by the significance of the secret, and were observed for both self-reported and behavioral measures of self-punishment.

Psychological resilience in U.S. military veterans: A 2-year, nationally representative prospective cohort study
Psychological resilience in U.S. military veterans: A 2-year, nationally representative prospective cohort study. Kelly Isaacs et al. Journal of Psychiatric Research, v 84, Jan 2017, pp 301-309, https://doi.org/10.1016/j.jpsychires.2016.10.017
Highlights
• The current study suggests that most military veterans (67.7%) are resilient.
• Emotional stability and extraversion were longitudinal predictors of resilience.
• Gratitude, altruism, and endorsement of purpose in life predicted resilient status.
• Novel interventions for trauma-exposed veterans may target such modifiable factors.
Abstract: Although many cross-sectional studies have examined the correlates of psychological resilience in U.S. military veterans, few longitudinal studies have identified long-term predictors of resilience in this population. The current prospective cohort study utilized data from a nationally representative sample of 2157 U.S. military veterans who completed web-based surveys in two waves (2011 and 2013) as part of the National Health and Resilience in Veterans Study (NHRVS). Cluster analysis of cumulative lifetime exposure to potentially traumatic events and Wave 2 measures of current symptoms of posttraumatic stress, major depressive, and generalized anxiety disorders was performed to characterize different profiles of current trauma-related psychological symptoms. Different profiles were compared with respect to sociodemographic, clinical, and psychosocial characteristics. A three-group cluster analysis revealed a Control group with low lifetime trauma exposure and low current psychological distress (59.5%), a Resilient group with high lifetime trauma and low current distress (27.4%), and a Distressed group with both high trauma exposure and current distress symptoms (13.1%). These results suggest that the majority of trauma-exposed veterans (67.7%) are psychologically resilient. Compared with the Distressed group, the Resilient group was younger, more likely to be Caucasian, and scored lower on measures of physical health difficulties, past psychiatric history, and substance abuse. Higher levels of emotional stability, extraversion, dispositional gratitude, purpose in life, and altruism, and lower levels of openness to experiences predicted resilient status. Prevention and treatment efforts designed to enhance modifiable factors such as gratitude, sense of purpose, and altruism may help promote resilience in highly trauma-exposed veterans.

Openness to experience predicts intrinsic value shifts after deliberating one's own death
Openness to experience predicts intrinsic value shifts after deliberating one's own death. Mike Prentice, Tim Kasser and Kennon Sheldon. Death Studies,
Abstract: Individual differences that might moderate processes of value shifting during and after deliberating one's own death remain largely unexplored. Two studies measured participants' openness and relative intrinsic-to-extrinsic value orientation (RIEVO) before randomly assigning them to conditions in which they wrote about their own death or dental pain for 6 days, after which RIEVO was assessed again up to 12 days later. When participants confronted thoughts about their own death over a sustained period, high openness to experience helped them shift toward intrinsic values. Implications for understanding openness' role in value reorientation from existential deliberation processes are discussed.

Protecting the Innocence of Youth: Moral Sanctity Values Underlie Censorship From Young Children

Abstract: Three studies examined the relationship between people's moral values (drawing on moral foundations theory) and their willingness to censor immoral acts from children. Results revealed that diverse moral values did not predict censorship judgments. It was not the case that participants who valued loyalty and authority, respectively, sought to censor depictions of disloyal and disobedient acts. Rather, censorship intentions were predicted by a single moral value - sanctity. The more people valued sanctity, the more willing they were to censor from children, regardless of the types of violations depicted (impurity, disloyalty, disobedience, etc.). Furthermore, people who valued sanctity objected to indecent exposure only to apparently innocent and pure children - those who were relatively young and who had not been previously exposed to immoral acts. These data suggest that sanctity, purity, and the preservation of innocence underlie intentions to censor from young children.

Thinking More or Feeling Less? Explaining the Foreign-Language Effect on Moral Judgment
Thinking More or Feeling Less? Explaining the Foreign-Language Effect on Moral Judgment. Sayuri Hayakawa et al. Psychological Science, https://doi.org/10.1177/0956797617720944
Abstract: Would you kill one person to save five? People are more willing to accept such utilitarian action when using a foreign language than when using their native language. In six experiments, we investigated why foreign-language use affects moral choice in this way. On the one hand, the difficulty of using a foreign language might slow people down and increase deliberation, amplifying utilitarian considerations of maximizing welfare. On the other hand, use of a foreign language might stunt emotional processing, attenuating considerations of deontological rules, such as the prohibition against killing. Using a process-dissociation technique, we found that foreign-language use decreases deontological responding but does not increase utilitarian responding. This suggests that using a foreign language affects moral choice not through increased deliberation but by blunting emotional reactions associated with the violation of deontological rules.

I Lie? We Lie! Why? Experimental Evidence on a Dishonesty Shift in Groups
I Lie? We Lie! Why? Experimental Evidence on a Dishonesty Shift in Groups. Martin Kocher, Simeon Schudy & Lisa Spantig. Management Science, https://doi.org/10.1287/mnsc.2017.2800
Abstract: Unethical behavior such as dishonesty, cheating and corruption occurs frequently in organizations or groups. Recent experimental evidence suggests that there is a stronger inclination to behave immorally in groups than individually. We ask if this is the case, and if so, why. Using a parsimonious laboratory setup, we study how individual behavior changes when deciding as a group member. We observe a strong dishonesty shift. This shift is mainly driven by communication within groups and turns out to be independent of whether group members face payoff commonality or not (i.e., whether other group members benefit from one's lie). Group members come up with and exchange more arguments for being dishonest than for complying with the norm of honesty. Thereby, group membership shifts the perception of the validity of the honesty norm and of its distribution in the population.

Ignoring alarming news brings indifference: Learning about the world and the self

Abstract: The broadcast of media reports about moral crises such as famine can subtly depress rather than activate moral concern. Whereas much research has examined the effects of media reports that people attend to, social psychological analysis suggests that what goes unattended can also have an impact. ***We test the idea that when vivid news accounts of human suffering are broadcast in the background but ignored, people infer from their choice to ignore these accounts that they care less about the issue, compared to those who pay attention and even to those who were not exposed***. Consistent with research on self-perception and attribution, three experiments demonstrate that participants who were nudged to distract themselves in front of a television news program about famine in Niger (Study 1), or to skip an online promotional video for the Niger famine program (Study 2), or who chose to ignore the famine in Niger television program in more naturalistic settings (Study 3) all assigned lower importance to poverty and to hunger reduction compared to participants who watched with no distraction or opportunity to skip the program, or to those who did not watch at all.

Strongest anti-Muslim attitudes are found among the nonreligious in secularized countries
Secular Tolerance? Anti-Muslim Sentiment in Western Europe. Egbert Ribberink, Peter Achterberg and Dick Houtman. Journal for the Scientific Study of Religion, http://onlinelibrary.wiley.com/doi/10.1111/jssr.12335/abstract
Abstract: The literature about secularization proposes two distinct explanations of anti-Muslim sentiment in secularized societies. The first theory understands it in terms of religious competition between Muslims and the remaining minority of orthodox Protestants; the second understands it as resulting from value conflicts between Muslims and the nonreligious majority. The two theories are tested by means of a multilevel analysis of the European Values Study 2008. Our findings indicate that, ***although more secularized countries are on average more tolerant towards Muslims and Islam, strongest anti-Muslim attitudes are nonetheless found among the nonreligious in these countries***.

Fearless dominance associated with success (being employed, higher household income)
Benning, Stephen & Molina, Stephany & A Dowgwillo, Emily & Patrick, Christopher & Miller, Karen & B Storrow, Alan. (2017). Psychopathy in the Medical Emergency Department. Journal of Personality Disorders, https://www.researchgate.net/publication/318911224_Psychopathy_in_the_Medical_Emergency_Department
Abstract: Psychopathy is a personality disorder representing an admixture of a fearless and dominant temperament with an impulsive and antisocial orientation. A sample of 1026 participants in the waiting room of the medical emergency department of a city hospital exhibited levels of fearless dominance similar to public university undergraduates and federal inmates; their levels of impulsive antisociality fell between federal and state inmates. Both psychopathy factors were correlated with male gender, younger age, and more frequent average alcohol consumption. Fearless dominance was associated with agentic success (e.g., being employed, higher household income), fewer psychological problems, and less use of psychotropic medications, including anxiolytics. Impulsive antisociality was negatively related to both agentic and communal (e.g., ever being married) success and positively correlated with substance use and self-reported bipolar, ADHD, and psychotic psychiatric conditions. Furthermore, only impulsive antisociality was associated with presenting to the emergency department for physical injury or psychological disturbance.

The upper class guys have issues recognizing limits of their knowledge, consider world in flux and change, acknowledge and integrate different perspectives in interpersonal situations
Brienza, Justin P, and Igor Grossmann. “Social Class and Wise Reasoning About Interpersonal Conflicts Across Regions, Persons and Situations”. Open Science Framework, Aug 21 2017, osf.io/wkgvm
Abstract: We propose that class is inversely related to a propensity of utilizing wise reasoning (recognizing limits of their knowledge, consider world in flux and change, acknowledge and integrate different perspectives) in interpersonal situations, contrary to established class advantage in abstract cognition. Two studies—an on-line survey from regions differing in economic affluence (N = 2,145) and a representative in-lab study with stratified sampling of adults from working and middle-class backgrounds (N = 299)—tested this proposition, indicating that higher social class consistently related to lower levels of wise reasoning across different levels of analysis, including regional and individual differences, and subjective construal of specific situations. The results held across personal and standardized hypothetical situations, across self-reported and observed wise reasoning, and when controlling for fluid and crystallized cognitive abilities. Consistent with the ecological framework, class differences in wise reasoning were specific to interpersonal (vs. societal) conflicts. These findings suggest that higher social class may also weigh individuals down by providing the ecological constraints that undermine wise reasoning about interpersonal affairs.
My commentary: The powerful and the rich have greater IQ and are accustomed to showing better performance in logic, and maybe due to this they fall into the excess of confidence, hubristic behavior, which prevents recognizing limits of their knowledge. If I remember well, this was more acute in the humanities, because they do not bang their heads so easily with really difficult problems.
When Newton found his laws of gravity, he soon realized that the three bodies problem was unsolvable (unlike the two bodies problem, like Moon-Earth interactions, or Sun-Earth interactions). Just that, to consider Moon, Earth and Sun, was not solvable analytically... One needs approximations to find solutions. And it was a normal thing decades ago that in the examinations, professors put questions that couldn't be completed in the time you got for your exam (now this is not possible, the student could be traumatized by the experience :-) ). This, finding so easily and so soon problems that exceed your abilities is something that makes you pause. And the guys in the humanities are much more cavalier with their skills...
Obviously, most of the rich are lawyers, etc., not mathematicians or physicists.

It is true that " Impulsive antisociality was negatively related to both agentic and communal (e.g., ever being married) success," so success (like being rich or having high status) helps contain impulsivity...

Smart Conformists: Children and Adolescents Associate Conformity With Intelligence Across Cultures
Wen, N. J., Clegg, J. M. and Legare, C. H. (2017), Smart Conformists: Children and Adolescents Associate Conformity With Intelligence Across Cultures. Child Dev. doi:10.1111/cdev.12935
Abstract: The current study used a novel methodology based on multivocal ethnography to assess the relations between conformity and evaluations of intelligence and good behavior among Western (U.S.) and non-Western (Ni-Vanuatu) children (6- to 11-year-olds) and adolescents (13- to 17-year-olds; N = 256). Previous research has shown that U.S. adults were less likely to endorse high-conformity children as intelligent than Ni-Vanuatu adults. The current data demonstrate that in contrast to prior studies documenting cultural differences between adults' evaluations of conformity, children and adolescents in the United States and Vanuatu have a conformity bias when evaluating peers' intelligence and behavior. Conformity bias for good behavior increases with age. The results have implications for understanding the interplay of conformity bias and trait psychology across cultures and development.

Lawyer CEOs get better results with less litigation
Henderson, M. Todd and Hutton, Irena and Jiang, Danling and Pierson, Matthew, Lawyer CEOs (February 21, 2017). Available at SSRN: https://ssrn.com/abstract=2923136
Abstract: We examine the value of CEOs with specialized professional skills by focusing on CEOs with law degrees and their effect on corporate litigation. We find that lawyer CEOs are associated with both lower litigation frequency and less severe litigation. This relation is observed for most of nine types of common corporate litigation. This reduction in litigation is achieved, in part, through a decrease in activities that can lead to litigation, such as earnings management, and an increase in legal oversight by directors with legal expertise. Moreover, CEOs with legal training are associated with higher value in firms with high litigation risk and growth firms.

Too Lucky to be True - Fairness Views under the Shadow of Cheating
Bortolotti, Stefania; Soraperra, Ivan; Sutter, Matthias; Zoller, Claudia (2017) : Too Lucky to be True - Fairness Views under the Shadow of Cheating, CESifo Working Paper, No. 6563. http://hdl.handle.net/10419/167549
Abstract: The steady increase in inequality over the past decades has revived a lively debate about what can be considered a fair distribution of income. Public support for the extent of redistribution typically depends on the perceived causes of income inequality, such as differences in effort, luck, or opportunities. We study how fairness views and the extent of redistribution are affected by a hitherto overlooked, but relevant factor: immoral self-serving behavior that can lead to increased inequality. We focus on situations in which the rich have potentially acquired their fortunes by means of cheating. In an experiment, we let third parties redistribute resources between two stakeholders who could earn money either by choosing a safe amount or by engaging in a risky, but potentially more profitable, investment.

Although third parties cannot verify cheating, ***we find that the mere suspicion of cheating changes fairness views of third parties considerably and leads to a strong polarization. When cheating opportunities are present, the share of subjects redistributing money from rich to poor stakeholders triples and becomes as large as the fraction of libertarians - i.e., participants who never redistribute***. Without cheating opportunities, libertarian fairness views dominate, while egalitarian views are much less prevalent. These results indicate that fairness views and attitudes towards redistribution change significantly when people believe that income inequality is the result of cheating by the rich.

Abstract: The steady increase in inequality over the past decades has revived a lively debate about what can be considered a fair distribution of income. Public support for the extent of redistribution typically depends on the perceived causes of income inequality, such as differences in effort, luck, or opportunities. We study how fairness views and the extent of redistribution are affected by a hitherto overlooked, but relevant factor: immoral self-serving behavior that can lead to increased inequality. We focus on situations in which the rich have potentially acquired their fortunes by means of cheating. In an experiment, we let third parties redistribute resources between two stakeholders who could earn money either by choosing a safe amount or by engaging in a risky, but potentially more profitable, investment. In one treatment, the outcome of the risky investment is determined by a random move, while in another treatment stakeholders can cheat to obtain the more profitable outcome. Although third parties cannot verify cheating, ***we find that the mere suspicion of cheating changes fairness views of third parties considerably and leads to a strong polarization. When cheating opportunities are present, the share of subjects redistributing money from rich to poor stakeholders triples and becomes as large as the fraction of libertarians - i.e., participants who never redistribute***. Without cheating opportunities, libertarian fairness views dominate, while egalitarian views are much less prevalent.

Diane Coffey and Dean Spears' Where India Goes --- by Alex Tabarrok
Where India Goes, by Alex Tabarrok on August 28, 2017.
Where India Goes [https://www.amazon.com/Where-India-Goes-Abandoned-Development/dp/9352645650], a book about the problem of open defecation in India [...] Written by Diane Coffey and Dean Spears [...].
Drawing on the academic literature, Coffey and Spears show that open defecation sickens and kills children, stunts their growth, and lowers their IQ all of which shows up in reduced productivity and wages in adulthood.
The dangers of open defecation are clear. Moreover, Gandhi said that “Sanitation is more important than independence” and Modi said “toilets before temples,” yet in India some half a billion people still do not use latrines. Why not? Jean Dreze and Amartya Sen (2013, https://www.amazon.com/Uncertain-Glory-India-Contradictions-2013-07-04/dp/B01K949958), offer a typical explanation:
In 2011 half of all Indian households did not have access to toilets, forcing them to resort to open defecation on a daily basis…
The phrasing presents the issues as one of lack of access that forces people to resort to open defecation. From this perspective the solution seems simple, provide access. After all, if you or I had access to toilets we would use them so if someone else isn’t using toilets it must be because they don’t have access. A bit of thought, however, dispels this notion.
[...]
For many people in India, open defecation is preferred to latrine use. The reasons relate to issues of ritual purity and caste. Latrines in or near homes are considered polluting, not in a physical so much as a spiritual or ritual sense. Latrine cleaning is also associated with the Dalit (out)-caste, in itself a polluting category (hence untouchable). That is, the impurity of defecation and caste are mutually reinforcing. As a result, using or, even worse, cleaning latrines is considered a ritual impurity. The problem of open defecation is thus intimately tied up with Hindu notions of purity and caste which many do not want to discuss, let alone condemn.
In the villages the idea of open defecation is also associated with clean air, exercise, and health. Thus, in surveys “both men and women speak openly about the benefits of open defecation and even associate it with health and longevity.” Even many women prefer open defecation if only because it gives them a chance to get out of the house and have some freedom of movement.

Geographic Accessibility Of Food Outlets Not Associated With Body Mass Index Change, 1.7million veterans
Geographic Accessibility Of Food Outlets Not Associated With Body Mass Index Change Among Veterans, 2009–14. Shannon Zenk et al. Health Affairs, August 2017, vol. 36 no. 8 1433-1442, http://content.healthaffairs.org/content/36/8/1433.short
Abstract: In recent years, various levels of government in the United States have adopted or discussed subsidies, tax breaks, zoning laws, and other public policies that promote geographic access to healthy food. However, there is little evidence from large-scale longitudinal or quasi-experimental research to suggest that the local mix of food outlets actually affects body mass index (BMI). We used a longitudinal design to examine whether the proximity of food outlets, by type, was associated with BMI changes between 2009 and 2014 among 1.7 million veterans in 382 metropolitan areas. We ***found no evidence that either absolute or relative geographic accessibility of supermarkets, fast-food restaurants, or mass merchandisers was associated with changes in an individual’s BMI over time***. While policies that alter only geographic access to food outlets may promote equitable access to healthy food and improve nutrition, our findings suggest they will do little to combat obesity in adults.

My commentary: We should stop saying things that we suspected were not true and now we know (1.7 million veterans studied) are not true. Being close to or passing by junk food outlets is not causing obesity...

Crowding increases calorie consumption
The Impact of Crowding on Calorie Consumption. Stefan Hock and Rajesh Bagchi. Journal of Consumer Research, https://doi.org/10.1093/jcr/ucx088
Abstract: Consumer behavior is often influenced by subtle environmental cues, such as temperature, color, lighting, scent or sound. We explore the effects of a not-so-subtle cue — human crowding — on calorie consumption. Although crowding is an omnipresent factor, it has received little attention in the marketing literature. We present six studies showing that crowding increases calorie consumption. These effects occur because crowding increases distraction, which hampers cognitive thinking and evokes more affective processing. When consumers process information affectively, they consume more calories. We show the specific reason for the increase in calories. When given a choice between several different options, people select and eat higher-calorie items, but when presented with only one option, people eat more of the same food item. We document this process, rule out alternative explanations, and discuss theoretical and managerial implications.

El comportamiento del consumidor es a menudo influenciado por señales ambientales sutiles, tales como temperatura, color, iluminación, olor o sonido. Exploramos los efectos de una no tan sutil señal - el hacinamiento humano - en el consumo de calorías. Aunque el hacinamiento es un factor omnipresente, ha recibido poca atención en la literatura de marketing. Presentamos seis estudios que muestran que el hacinamiento aumenta el consumo de calorías. Estos efectos ocurren debido al hecho de que el pensamiento cognitivo no es el mismo. Cuando los consumidores procesan información de manera afectiva, consumen más calorías. Se muestra la razón específica para el aumento de calorías. Cuando se les da una opción entre varias opciones diferentes, las personas seleccionan y comen artículos de más calorías, pero cuando se les presenta con una sola opción, las personas comen más del mismo alimento. Documentamos este proceso, descartamos las explicaciones alternativas y discutimos las implicaciones teóricas y gerenciales.

Anti-Profit Beliefs: How People Neglect the Societal Benefits of Profit
Anti-Profit Beliefs: How People Neglect the Societal Benefits of Profit. Amit Bhattacharjee, Jason Dana & Jonathan Baron. Journal of Personality and Social Psychology, https://www.ncbi.nlm.nih.gov/pubmed/28726437
Abstract: Profit-seeking firms are stereotypically depicted as immoral and harmful to society. At the same time, profit-driven enterprise has contributed immensely to human prosperity. Though scholars agree that profit can incentivize societally beneficial behaviors, people may neglect this possibility. In 7 studies, we show that people see business profit as necessarily in conflict with social good, a view we call anti-profit beliefs. Studies 1 and 2 demonstrate that U.S. participants hold anti-profit views of real U.S. firms and industries. Study 3 shows that hypothetical organizations are seen as doing more harm when they are labeled “for-profit” rather than “non-profit,” while Study 4 shows that increasing harm to society is viewed as a strategy for increasing a hypothetical firm’s long-run profitability. Studies 5–7 demonstrate that carefully prompting subjects to consider the long run incentives of profit can attenuate anti-profit beliefs, while prompting short run thinking does nothing relative to a control. Together, these results suggest that the default view of profits is zero-sum. While people readily grasp how profit can incentivize firms to engage in practices that harm others, they neglect how it can incentivize firms to engage in practices that benefit others. Accordingly, people’s stereotypes of profit-seeking firms are excessively negative. Even in one of the most market-oriented societies in history, people doubt the contributions of profit-seeking industry to societal progress.

Sectarianism and Social Conformity: Evidence from Egypt
Sectarianism and Social Conformity: Evidence from Egypt. Steven Brooke. Political Research Quarterly, https://doi.org/10.1177/1065912917717641
Abstract: Why might citizens adopt exaggerated public antagonism toward outgroups? When this is so, how much do public and private attitudes diverge? I argue that expanding exclusionary rhetoric against outgroups can create social pressures that incentivize ordinary citizens to adopt bigoted attitudes to avoid ostracism from their own majority community. Based on an investigation of Egypt during the Arab Spring, I identify the emergence and diffusion of a norm of discrimination against the country’s tiny Shi’a population. Under these conditions, a substantial portion of Sunni citizens adopted and countenanced anti-Shi’a bigotry not because they truly believed it, but rather because they feared the consequences of expressing public support for coexistence. A variety of qualitative evidence traces the growth of anti-Shi’a sentiment during this period, while original survey data show that over 80 percent of Sunni respondents openly expressed anti-Shi’a attitudes. Yet when asked about their attitudes via an item count technique, a method that grants a reprieve from social pressures, the percentage of respondents expressing discriminatory views toward the Shi’a dropped to just over 40 percent. One implication is that sectarian attitudes in the region are as much the product of malleable social and political pressures as deeply rooted preferences.

Biomarkers and Long-term Labour Market Outcomes: The Case of Creatine
Biomarkers and Long-term Labour Market Outcomes: The Case of Creatine. Petri Böckerman et al. Journal of Economic Behavior & Organization, Volume 142, October 2017, Pages 259-274, https://doi.org/10.1016/j.jebo.2017.08.003
Abstract: Using the Young Finns Study (YFS) combined with the Finnish Linked Employer-Employee Data (FLEED) we show that quantities of creatine measured in 1980 prior to labour market entry affect labour market outcomes over the period 1990-2010. Those with higher levels of creatine (proxied by urine creatinine) prior to labour market entry spend more time in the labour market in the subsequent two decades and earn more. The associations between creatine and labour market outcomes are robust to controlling for other biomarkers, educational attainment and parental background. Creatine is a naturally occurring nitrogenous organic acid which supplies energy to body cells, including muscles. Our findings are consistent with high energy levels, induced by creatine, leading to productivity-enhancing traits such as a high propensity for effort, perseverance, and high-commitment.
My commentary: What should we do with this? Many people is not energetic enough, is weak and take too many leaves of absence on medical grounds... Should everybody, but specially we guys with physical power and strong orientation to success and commitment to the companies and customers, contribute part of our paychecks to compensate for that part of the population who cannot work with our dedication but there is no possibility of cheating on us or riding free on us (because blood tests are objective indicators)? Like insurance for body weakness... I don't like much the idea, but it is true that a lot of people go to the workplace as if it were a jail in which to be punished and clearly it is not their fault in most cases. They got physical issues (like less creatine).
Maybe we guys with great work enjoyment could compensate the guys with less capability to put more effort with some cash rewards taken from our paychecks to make things even for them.
The companies could pay differentially those of us with more drive (paying us a bit less) and putting the money in a fund from where to pay those who are sick frequently, making their earnings "holes" shorter, smaller, thru their labor lives.If guys with less energy take leaves of absence for 15-30pct of their work life, missing totally or partially some years of work and earning less accordingly, the fund could make that hole much shorter and less deep, let's say 10pct of the work life.
Those extra years of earnings similar to those when they were full employees (adding payments to their disability paychecks so that they earn in semi-retirement the same than we healthy guys) make also for greater contributions to their pensions.
We should be able to make the calculations to know how much we'd need to give to such fund.

The Effect of a Supreme Court Decision Regarding Gay Marriage on Social Norms and Personal Attitudes
The Effect of a Supreme Court Decision Regarding Gay Marriage on Social Norms and Personal Attitudes. Margaret Tankard and Elizabeth Levy Paluck. Psychological Science, https://doi.org/10.1177/0956797617709594
Abstract: We propose that institutions such as the U.S. Supreme Court can lead individuals to update their perceptions of social norms, in contrast to the mixed evidence on whether institutions shape individuals' personal opinions. We studied reactions to the June 2015 U.S. Supreme Court ruling in favor of same-sex marriage. In a controlled experimental setting, we found that a favorable ruling, when presented as likely, shifted perceived norms and personal attitudes toward increased support for gay marriage and gay people. Next, a five-wave longitudinal time-series study using a sample of 1,063 people found an increase in perceived social norms supporting gay marriage after the ruling ***but no change in personal attitudes***. This pattern was replicated in a separate between-subjects data set. These findings provide the first experimental evidence that an institutional decision can change perceptions of social norms, which have been shown to guide behavior, even when individual opinions are unchanged.
