LGB respondents are more liberal than heterosexuals on 99 percent of 199 attitudinal items

Schnabel, Landon. 2017. “Sexual Orientation and Social Attitudes”. SocArXiv. August 23. www.osf.io/preprints/socarxiv/73xsz

Abstract: Gender, race, and class strongly predict social attitudes and are at the core of social scientific theory and empirical analysis. Sexuality (i.e., same-sex behavior or LGB identity), however, is not as central a factor by which we conceptualize and systematize society. Using the General Social Survey, this study examines the effect of sexuality, gender, race, and education on 199 attitudinal items. Sexuality consistently and substantially predicts a broad range of attitudes. Measured by partnering behavior, sexuality significantly predicts attitudes on 137 items. On all 137 of these items, LGB respondents are more liberal than heterosexuals. Irrespective of significance, LGB respondents are more liberal than heterosexuals on 99 percent of 199 total items. These patterns are consistent with the underdog principle of marginalized identity and progressive values. Sexuality predicts attitudes at least as consistently as gender, race, and education. I argue that future work should pay more attention to sexuality as a core factor in social scientific theory and empirical analysis.

Introverts emerge less as leaders because they engage in higher levels of forecasted negative affect

The failure of introverts to emerge as leaders: The role of forecasted affect. Andrew Spark, Timothy Stansmore, and Peter O'Connor. Personality and Individual Differences, Volume 121, January 15 2018, Pages 84–88. https://doi.org/10.1016/j.paid.2017.09.026

Highlights
•    Introverts are less likely to emerge as leaders compared to extraverts.
•    Forecasted affect is proposed to mediate this relationship.
•    Forecasted positive affect has no mediation effect.
•
    Forecasted negative affect fully mediates the relationship.

Abstract: Introverts are less likely to emerge as leaders than extraverts, however the existing literature provides little explanation as to why. To investigate the potential cause of this trait-based difference in emergent leadership, we measured trait extraversion in a sample of 184 business students and studied their leadership-related behavior in an unstructured group task. We drew from a model of forecasted affect to hypothesize that introverts would be less likely to emerge as leaders based on their belief that engaging in the necessary extraverted behavior would be unpleasant/unenjoyable (i.e. they would forecast higher levels of negative affect compared to extraverts). Consistent with this, we found that introverts were less likely to emerge as leaders, and that forecasted negative affect fully accounted for the relationship between extraversion and peer-rated emergent leadership. We therefore argue that introverts fail to emerge as leaders as often as extraverts because they engage in higher levels of forecasted negative affect and that these forecasts impede their emergent leadership potential.

Disgust and Deontology: Trait Sensitivity to Contamination Promotes a Preference for Order, Hierarchy, and Rule-Based Moral Judgment

Disgust and Deontology: Trait Sensitivity to Contamination Promotes a Preference for Order, Hierarchy, and Rule-Based Moral Judgment. Jeffrey S. Robinson, Xiaowen Xu, and Jason E. Plaks. Social Psychological and Personality Science, https://doi.org/10.1177/1948550617732609

Abstract: Models of moral judgment have linked generalized emotionality with deontological moral judgment. The evidence, however, is mixed. Other research has linked the specific emotion of disgust with generalized moral condemnation. Here too, the evidence is mixed. We suggest that a synthesis of these two literatures points to one specific emotion (disgust) that reliably predicts one specific type of moral judgment (deontological). In all three studies, we found that trait disgust sensitivity predicted more extreme deontological judgment. In Study 3, with deontological endorsement and consequentialist endorsement operationalized as independent constructs, we found that disgust was positively associated with deontological endorsement but was unrelated to consequentialist endorsement. Across studies, the disgust–deontology link was mediated by individual difference variables related to preference for order (right-wing authoritarianism and intolerance for ambiguity). These data suggest a more precise model of emotion and moral judgment that identifies specific emotions, specific types of moral judgment, and specific motivational pathways.

A Study of Political Candidacy Among Swedish Adoptees -- Strong transmission in candidacy status between rearing mothers and their daughter

It Runs in the Family: A Study of Political Candidacy Among Swedish Adoptees. Oskarsson, S., Dawes, C.T. & Lindgren, KO. Polit Behav (2017). https://doi.org/10.1007/s11109-017-9429-1

Abstract: What motivates citizens to run for office? Recent work has shown that early life parental socialization is strongly associated with a desire to run for office. However, parents not only shape their children’s political environment, they also pass along their genes to those same children. A growing area of research has shown that individual differences in a wide range of political behaviors and attitudes are linked to genetic differences. As a result, genetic factors may confound the observed political similarities among parents and their children. This study analyzes Swedish register data containing information on all nominated and elected candidates in the ten parliamentary, county council, and municipal elections from 1982 to 2014 for a large sample of adoptees and their adoptive and biological parents. By studying the similarity in political ambition within both adoptive and biological families, our research design allows us to disentangle so-called “pre-birth” factors, such as genes and pre-natal environment, and “post-birth” factors like parental socialization. We find that the likelihood of standing as a political candidate is twice as high if one’s parent has been a candidate. We also find that the effects of pre-birth and post-birth factors are approximately equal in size. In addition, we test a number of potential pre- and post-birth transmission mechanisms. First, disconfirming our expectations, the pre-birth effects do not seem to be mediated by cognitive ability or leadership skills. Second, consistent with a role modeling mechanism, we find evidence of a strong transmission in candidacy status between rearing mothers and their daughters.

Immobile Australia: Surnames Show Strong Status Persistence, 1870–2017

Immobile Australia: Surnames Show Strong Status Persistence, 1870–2017. Gregory Clark, Andrew Leigh, and Mike Pottenger. IZA DP No. 11021. http://legacy.iza.org/en/webcontent/publications/papers/viewAbstract?dp_id=11021

Abstract: The paper estimates long run social mobility in Australia 1870–2017 tracking the status of rare surnames. The status information includes occupations from electoral rolls 1903–1980, and records of degrees awarded by Melbourne and Sydney universities 1852–2017. Status persistence was strong throughout, with an intergenerational correlation of 0.7–0.8, and no change over time. Notwithstanding egalitarian norms, high immigration and a well-targeted social safety net, Australian long-run social mobility rates are low. Despite evidence on conventional measures that Australia has higher rates of social mobility than the UK or USA (Mendolia and Siminski, 2016), status persistence for surnames is as high as that in England or the USA. Mobility rates are also just as low if we look just at mobility within descendants of UK immigrants, so ethnic effects explain none of the immobility.

Women perceive men's limbal rings as a health cue when in mood for casual sex

Put a (limbal) ring on it: Women perceive men's limbal rings as a health cue in short-term mating domains. Mitch Brown and Donald F Sacco. Available from: https://www.researchgate.net/publication/319321311_Put_a_limbal_ring_on_it_Women_perceive_men%27s_limbal_rings_as_a_health_cue_in_short-term_mating_domains

Abstract: Limbal rings are dark annuli encircling the iris that fluctuate in visibility based on health and age. Research also indicates their presence augments facial attractiveness. Given individuals’ prioritization of health cues in short-term mates, those with limbal rings may be implicated as ideal short-term mates. Three studies tested whether limbal rings serve as veridical health cues, specifically the extent to which this cue enhances a person’s value as a short-term mating partner. In Study 1, targets with limbal rings were rated as healthier, an effect that was stronger for female participants and male targets. In Study 2, temporally activated short-term mating motives led women to report a heightened preference for targets with limbal rings. In Study 3, women rated targets with limbal rings as more desirable short-term mates. Results provide evidence for limbal rings as veridical cues to health, particularly in relevant mating domains.

Accurate Genomic Prediction Of Human Height -- "within a few cm of the prediction"

Accurate Genomic Prediction Of Human Height. Louis Lello, Steven G Avery, Laurent Tellier, Ana Vazquez, Gustavo de los Campos, and Stephen D. H. Hsu. BioRxiv, Sep 19 2017. doi: https://doi.org/10.1101/190124

Abstract: We construct genomic predictors for heritable and extremely complex human quantitative traits (height, heel bone density, and educational attainment) using modern methods in high dimensional statistics (i.e., machine learning). Replication tests show that these predictors capture, respectively, ~40, 20, and 9 percent of total variance for the three traits. For example, predicted heights correlate ~0.65 with actual height; actual heights of most individuals in validation samples are within a few cm of the prediction. The variance captured for height is comparable to the estimated SNP heritability from GCTA (GREML) analysis, and seems to be close to its asymptotic value (i.e., as sample size goes to infinity), suggesting that we have captured most of the heritability for the SNPs used. Thus, our results resolve the common SNP portion of the "missing heritability" problem - i.e., the gap between prediction R-squared and SNP heritability. The ~20k activated SNPs in our height predictor reveal the genetic architecture of human height, at least for common SNPs. Our primary dataset is the UK Biobank cohort, comprised of almost 500k individual genotypes with multiple phenotypes. We also use other datasets and SNPs found in earlier GWAS for out-of-sample validation of our results.

Psychological roadblocks to the adoption of self-driving vehicles

Self-driving cars offer a bright future, but only if the public can overcome the psychological challenges that stand in the way of widespread adoption. We discuss three: ethical dilemmas, overreactions to accidents, and the opacity of the cars’ decision-making algorithms — and propose steps towards addressing them. Azim Shariff, Jean-François Bonnefon and Iyad Rahwan

The widespread adoption of autonomous vehicles promises to make us happier, safer and more efficient. Manufacturers are speeding past the remaining technical challenges to the cars’ readiness. But the biggest roadblocks standing in the path of mass adoption may be psychological, not technological; 78% of Americans report fearing riding in an autonomous vehicle, with only 19% indicating that they would trust the car1.  Trust — the comfort in making oneself vulnerable to another entity in the pursuit of some benefit — has long been recognized as critical to the adoption of automation, and becomes even more important as both the complexity of automation and the vulnerability of the users increase2. For autonomous vehicles, which will need to navigate our complex urban environment with the power of life and death, trust will determine how widely the cars are adopted by consumers, and how tolerated they are by everyone else. Achieving the bright future promised by autonomous vehicles will require overcoming the psychological barriers to trust. Here we diagnose three factors underlying this resistance and offer a plan of action (see Table 1).


The dilemmas of autonomous ethics

The necessity for autonomous vehicles to make ethical decisions leads to a series of dilemmas for their designers, regulators and the public at large3. These begin with the need for an autonomous vehicle to decide how it will operate in situations where its actions could decrease the risk of harming its own passengers by increasing the risk to a potentially larger number of non-passengers (for example, pedestrians and other drivers).  While these decisions will most often involve probabilistic trade-offs in small-risk manoeuvres, at its extreme the decision could involve an autonomous vehicle determining whether to harm its passenger to spare the lives of two or more pedestrians, or vice versa (Fig. 1).

In handling these situations, the cars may operate as utilitarians, minimizing total risk to people regardless of who they are, or as self-protective, placing extra weight on the safety of their own passengers. Human drivers make such decisions instinctively in a split second, and thus cannot be expected to abide by whatever ethical principle they formulated in the comfort of their armchair.  But autonomous vehicle manufacturers have the luxury of moral deliberation — and thus the responsibility of that deliberation.  The existence of this ethical dilemma in turn produces a social dilemma. People are inconsistent about what principles they want autonomous vehicles to follow. Individuals recognize the utilitarian approach to be the more ethical, and as citizens, want the cars to save the greater number. But as consumers, they want self-protective cars3.  As a result, adopting either strategy brings its own risks for manufacturers — a selfprotective strategy risks public outrage, whereas a utilitarian strategy may scare consumers away.

Both the ethical and social dilemmas will need to be addressed to earn the trust of the public. And because it seems unlikely that regulators will adopt the strictest selfprotective solution — in which autonomous vehicles would never harm their passengers, however small the danger to passengers and large the risk to others — we will have to grapple with consumers’ fear that their car might someday decide to harm them.  To overcome that fear, we need to make people feel both safe and virtuous about owning an autonomous vehicle. To make

Psychological challenge Suggested actions
The dilemmas of autonomous ethics. People are torn between how they want autonomous vehicles to ethically behave; they morally believe the vehicles should operate under utilitarian principles, but prefer to buy vehicles that prioritize their own lives as passengers. The idea of a car sacrificing its passengers deters people from purchasing an autonomous vehicle. Shift the discussion from the relative risk of injury to the absolute risk. Appeal to consumers’ desire for virtue signalling.

to most effectively convey the absolute reduction in risk to passengers due to overall accident reduction, so that it is not irrationally overshadowed by a potentially small increase in relative risk that passengers face in relation to other road users.  Communication about the overall safety benefits of autonomous vehicles could be further leveraged to appeal to potential consumers’ concerns about self-image and reputation. Virtue signalling is a powerful motivation for buying ethical products, but only when the ethicality is conspicuous4.  Allowing the altruistic benefits of autonomous vehicles to reflect on the consumer can change the conversation about autonomous vehicle ethics and prove itself to be a marketing asset. The most relevant example of successful virtue consumerism is that of the Toyota Prius, a hybrid-electric automobile whose distinctive shape has allowed owners to signal their environmental commitment. However, whereas ‘green’ marketing can backfire for those politically unaligned with the environmental movement5, the package of virtues connected with autonomous vehicles — safety, but also reductions in traffic and parking congestion — contain uncontroversial values that allow consumers to advertise themselves as safe, smart and prosocial.


Risk heuristics and algorithm aversion

When the first traffic fatality involving Tesla’s Autopilot occurred in May 2016, it was covered by every major news organization — a feat unmatched by any of the other 40,200 US traffic fatalities that year. We can expect an even larger reaction the first time an autonomous vehicle kills a pedestrian, or kills a child, or two autonomous vehicles crash into each other. Outsized media coverage of crashes involving autonomous vehicles may feed and amplify people’s fears by tapping into the availability heuristic (risks are subjectively higher when they come to mind easily) and affective heuristic (risks are perceived to be higher when they evoke a vivid emotional reaction). As with airplane crashes, the more disproportionate — and disproportionately sensational — the coverage that autonomous vehicle accidents receive, the more exaggerated people will perceive the risk and dangers of these cars in comparison to those of traditional human-driven ones. Worse, for autonomous vehicles, these reactions may be compounded by algorithm aversion6, the tendency for people to more rapidly lose faith in an erring decision-making algorithm than in humans making comparable errors.  These reactions could derail the adoption of autonomous vehicles through numerous paths; they could directly deter consumers, provoke politicians to enact suffocating restrictions, or create outsized liability issues — fuelled by court and jury overreactions — that compromise the financial feasibility of autonomous vehicles.  Each path could slow or even stall widespread adoption.

Countering these powerful psychological effects may prove especially difficult.  Nevertheless, there are opportunities.  Autonomous vehicle spokespeople should prepare the public for the inevitability of accidents — not overpromising infallibility, but still emphasizing autonomous vehicles’ safety advantages over human drivers.  One barrier that prevents people from adopting (superior) algorithms over human judgment is overconfidence in one’s own performance7 — something famously prevalent in driving. Manufacturers should also be open about algorithmic improvements.  Autonomous vehicles are better portrayed as being perfected, not as being perfect.  Politicians and regulators can also play a role in managing overreaction.  Though human themselves, and ultimately answerable to the public, legislators should resist capitulating to the public’s fears of low-probability risks8. They should instead educate the public about the actual risks and, if moved to act, do so in a calculated way, perhaps by offering the public ‘fear placebos'8 — high-visibility, low-cost gestures that do the most to assuage the public’s fears without undermining the real benefits that autonomous vehicles might bring.  Asymmetric information and the theory of the machine mind

The dubious reputation of the CIA is sometimes blamed on the asymmetry between the secrecy of their successes and the broad awareness of their failures. Autonomous vehicles will face a similar challenge.  Passengers will be acutely aware of the cars’ rare failures — leading to the issues described above — but may be blissfully unaware of all the small successes and optimizations.  This asymmetry of information is part of a larger psychological barrier to the trust in autonomous vehicles: the opacity to the decision-making occurring under the hood.  If trust is characterized by the willingness to yield vulnerability to another entity, it is critical that people can comfortably predict and understand the behaviour of the other entity. Indeed, the European Union General Data Protection Regulation recently established the citizen’s “right to [...] obtain an explanation of the decision reached [...] and to challenge the decision” made by algorithms9.  However, full transparency may be neither possible nor optimal. Autonomous vehicle intelligence is driven in part by Fig. 1 | A schematic example of the ethical trade-offs that autonomous vehicles will need to make between the lives of passengers and pedestrians3. The visual comes from the Moral Machine website (http://moralmachine.mit.edu), which we launched to collect large-scale data from the public. So far, we have collected over 30 million decisions from over 3 million people.

machine learning, in which computers learn increasingly sophisticated patterns without being explicitly taught. This leaves underlying decision-making processes opaque even to the programmer (let alone the passenger).  But even if a detailed account of the computer’s decisions were available, it would only offer the end-user an incomprehensible deluge of information. The trend in many ‘lower stakes’ computer interfaces (for example, web browsers) has thus been in the opposite direction — hiding the complex decision-making of the machine to present a simple, minimalistic user experience.  For autonomous vehicles, although some transparency can improve trust, too much transparency into the explanations for the car’s actions can overwhelm the passenger, thereby increasing anxiety10.

Thus, what is most important for generating trust and comfort is not full transparency but communication of the correct amount and type of information to allow people to develop mental models (an abstract representation of the entity’s perceptions and decision rules) of the cars5 — a sort of theory of the machine mind. There is already a robust literature investigating what information is most crucial to communicate; however, most of this research has been conducted on artificial intelligence in industrial, residential or software interface settings. Not all of it will be perfectly transferable to autonomous vehicles, so researchers need to investigate what information best fosters predictability, trust and comfort in this new and specific setting.  Moreover, autonomous vehicles will need to communicate not just with their passengers, but with pedestrians, fellow drivers and the other stakeholders on the road. Currently, people decipher the intentions of other drivers through explicit signals (such as indicators, horns and gestures) and through assumptions based on the mental models formed of drivers (‘Why is she slowing down here?’ or ‘Why is he positioning himself like that?’). Everyone on the road will need to adjust their human models to those of autonomous vehicles, and the more research delineating what information people find crucial and comforting, the more seamless and less panicky this transition will be.


A new social contract

Automobiles began their transformational integration into our lives over a century ago.  In this time, a system of laws regulating the behaviour of drivers and pedestrians, and the designs and practices of manufacturers, has been introduced and continuously refined.  Today, the technologies that mediate these regulations, and the norms, fines and other punishments that enforce them, maintain just enough trust in the traffic system to keep it tolerable. Tomorrow, the integration of autonomous cars will be similarly transformational, but will occur over a much shorter timescale. In that time, we will need a new social contract that provides clear guidelines about who is responsible for different kinds of accidents, how monitoring and enforcement will be performed, and how trust among all stakeholders can be engendered.  Many challenges remain — hacking, liability and labour displacement issues, most significantly — but this social contract will be bound as much by psychological realities as by technological and legal ones. We have identified several here, but more work remains. We believe it is morally imperative for behavioural scientists of all disciplines to weigh in on this contract.  Every day the adoption of autonomous cars is delayed is another day that people will continue to lose their lives to the non-autonomous human drivers of yesterday.

Prolonged transport and cannibalism of mummified infant remains by a Tonkean macaque mother

Prolonged transport and cannibalism of mummified infant remains by a Tonkean macaque mother. Arianna De Marco, Roberto Cozzolino, and Bernard Thierry. Primates. https://link.springer.com/article/10.1007/s10329-017-0633-8

Abstract: Observations of animals’ responses to dying or dead companions raise questions about their awareness of states of helplessness or death of other individuals. In this context, we report the case of a female Tonkean macaque (Macaca tonkeana) that transported the body of her dead infant for 25 days and cannibalized its mummified parts. The mother appeared agitated in the first 2 days after the birth. She then took care of her infant’s corpse, which progressively dried and became mummified. In a third stage, the mother continued to transport the corpse as it started disintegrating, and she gnawed and consumed some parts of the remains. Our observations suggest that mummification of the body favored persistence of maternal behaviors by preserving the body’s shape. The female gradually proceeded from strong attachment to the infant’s body to decreased attachment, then finally full abandonment of the remains.

Anticipated regret from erring after following advice is greater than anticipated regret from erring after ignoring advice

Tzini, K., and Jain, K. (2017) The Role of Anticipated Regret in Advice Taking. J. Behav. Decision Making, doi: 10.1002/bdm.2048.

Abstract: Across five studies, we demonstrate that anticipated future regret influences receptiveness to advice. While making a revision to one's own judgment based on advice, people can anticipate two kinds of future regret: (a) the regret of following non-beneficial advice and (b) the regret of ignoring beneficial advice. In studies 1a (scenario task) and 1b (judgment task), we find that anticipated regret from erring after following advice is greater than anticipated regret from erring after ignoring advice. Furthermore, receptiveness decreases as the difference between anticipated regret from following and from ignoring advice increases. In study 2, we demonstrate that perceived justifiability of one's own initial decision is greater than that of advice. This difference in perceived justifiability influences anticipated regret and that, in turn, influences receptiveness. In study 3, we investigate the effect of advisor's expertise on perceived justifiability, anticipated regret, and receptiveness. In study 4, we propose and test an intervention to improve receptiveness based on self-generation of advice justifications. Participants who were asked to self-generate justifications for the advice were more receptive to it. This effect was mediated by perceived justifiability and anticipated regret. These findings shed further light on what prevents people from being receptive to advice and how this can be improved.

Resource Allocation Decisions: When Do We Sacrifice Efficiency in the Name of Equity?

Resource Allocation Decisions: When Do We Sacrifice Efficiency in the Name of Equity? Tom Gordon-Hecke et al. Interdisciplinary Perspectives on Fairness, Equity, and Justice, pp 93-105. https://link.springer.com/chapter/10.1007/978-3-319-58993-0_6

Abstract: Equity, or the idea that one should be compensated according to one’s respective contribution, is a fundamental principle for resource allocation. People tend to endorse equity in a wide range of contexts, from interpersonal relationships to public policy. However, at times, equity might come at the expense of efficiency. What do people do when they must waste resources to maintain equity? In this chapter, we adopt a behavioral perspective on such equity–efficiency trade-offs, reviewing the relevant findings from the social psychology, judgment and decision-making and behavioral economics literature. We show that whereas allocators will often choose to waste in the name of equity, this is not necessarily the case. We review various psychological aspects that affect the allocators’ decision.

The Facial Width-to-Height Ratio Predicts Sex Drive, Sociosexuality, and Intended Infidelity

The Facial Width-to-Height Ratio Predicts Sex Drive, Sociosexuality, and Intended Infidelity. Steven Arnocky et al. Archives of Sexual Behavior, https://link.springer.com/article/10.1007/s10508-017-1070-x

Abstract: Previous research has linked the facial width-to-height ratio (FWHR) to a host of psychological and behavioral characteristics, primarily in men. In two studies, we examined novel links between FWHR and sex drive. In Study 1, a sample of 145 undergraduate students revealed that FWHR positively predicted sex drive. There were no significant FWHR × sex interactions, suggesting that FWHR is linked to sexuality among both men and women. Study 2 replicated and extended these findings in a sample of 314 students collected from a different Canadian city, which again demonstrated links between the FWHR and sex drive (also in both men and women), as well as sociosexuality and intended infidelity (men only). Internal meta-analytic results confirm the link between FWHR and sex drive among both men and women. These results suggest that FWHR may be an important morphological index of human sexuality.

Contrary to prediction, kids these days are better able to delay gratification than they were in the past

Kids These Days: 50 years of the Marshmallow task. Protzko. https://osf.io/j9tuz/

Abstract: Have children gotten worse at their ability to delay gratification? We analyze the past 50 years of data on the Marshmallow test of delay of gratification. Children must wait to get two preferred treats; if they cannot wait, they only get one. Duration for how long children can delay has been associated with a host of positive life outcomes. Here we provide the first evidence on whether children’s ability to delay gratification has truly been decreasing, as theories of technology or a culture of instant gratification have predicted. Before analyzing the data, we polled 260 experts in cognitive development, 84% of who believed kids these days are getting worse or are no different. Contrary to this prediction, kids these days are better able to delay gratification than they were in the past, corresponding to a fifth of a standard deviation increase in ability per decade.

Belief in free will affects causal attributions when judging others’ behavior

Belief in free will affects causal attributions when judging others’ behavior. Oliver Genschow, Davide Rigoni, and Marcel Brass. Proceedings of the National Academy of Sciences, vol. 114 no. 38, 10071–10076, doi: 10.1073/pnas.1701916114

Significance: The question whether free will exists or not has been a matter of debate in philosophy for centuries. Recently, researchers claimed that free will is nothing more than a myth. Although the validity of this claim is debatable, it attracted much attention in the general public. This raises the crucial question whether it matters if people believe in free will or not. In six studies, we tested whether believing in free will is related to the correspondence bias—that is, people’s automatic tendency to overestimate the influence of internal as compared to external factors when interpreting others’ behavior. Overall, we demonstrate that believing in free will increases the correspondence bias and predicts prescribed punishment and reward behavior.

Abstract: Free will is a cornerstone of our society, and psychological research demonstrates that questioning its existence impacts social behavior. In six studies, we tested whether believing in free will is related to the correspondence bias, which reflects people’s automatic tendency to overestimate the influence of internal as compared to external factors when interpreting others’ behavior. All studies demonstrate a positive relationship between the strength of the belief in free will and the correspondence bias. Moreover, in two experimental studies, we showed that weakening participants’ belief in free will leads to a reduction of the correspondence bias. Finally, the last study demonstrates that believing in free will predicts prescribed punishment and reward behavior, and that this relation is mediated by the correspondence bias. Overall, these studies show that believing in free will impacts fundamental social-cognitive processes that are involved in the understanding of others’ behavior.

Maximizers maximize for both themselves and others, whereas satisficers satisfice for themselves but maximize for others

Do maximizers maximize for others? Self-other decision-making differences in maximizing and satisficing. Mo Luan , Lisha Fu , and Hong Li. Personality and Individual Differences, Volume 121, 15 January 2018, Pages 52–56, https://doi.org/10.1016/j.paid.2017.09.009

Highlights
•    Self-other decision-making differences between maximizers and satisficers exist.
•    Maximizers maximize for both themselves and others.
•    Satisficers satisfice for themselves but maximize for others.

Abstract: The current research provides initial evidence of self-other decision-making differences between maximizers and satisficers by focusing on how they make the tradeoff between the value and the effort an option requires when deciding for themselves and for others. Study 1 demonstrates that maximizers prefer a high-value but effort-consuming option both for themselves and for others, whereas satisficers prefer that option for others but not for themselves. Study 2 further shows that to attain high value with a choice, maximizers not only are willing to expend more effort themselves but also advise others to expend more effort; however, satisficers choose to expend less effort themselves but do not advise others to do so. In conclusion, the current research contributes to the relevant literature by demonstrating that maximizers maximize for both themselves and others, whereas satisficers satisfice for themselves but maximize for others.

Consumers in durable goods markets are rational and forward looking

Are consumers forward looking? Evidence from used iPhones. Kanis Saengchote & Voraprapa Nakavachara. Applied Economics Letters, Pages 1-5. http://dx.doi.org/10.1080/13504851.2017.1380286

ABSTRACT: This study examines the impact of planned obsolescence – the introduction of new models to make existing models obsolete – on secondary markets for mobile phones. Using data of over 320,000 used iPhones listings on Thailand’s largest online marketplace, we document that iPhone prices decrease with age, around 2.8–3.2% for each passing month. We find no evidence that the price decline accelerates after launches of new models (i.e. obsolescence), lending support to the view that consumer in durable goods markets are rational and forward looking.

Reasons Probably Won’t Change Your Mind: The Role of Reasons in Revising Moral Decisions

Stanley, M. L., Dougherty, A. M., Yang, B. W., Henne, P., & De Brigard, F. (2017). Reasons Probably Won’t Change Your Mind: The Role of Reasons in Revising Moral Decisions. Journal of Experimental Psychology: General. http://dx.doi.org/10.1037/xge0000368

Abstract: Although many philosophers argue that making and revising moral decisions ought to be a matter of deliberating over reasons, the extent to which the consideration of reasons informs people’s moral decisions and prompts them to change their decisions remains unclear. Here, after making an initial decision in 2-option moral dilemmas, participants examined reasons for only the option initially chosen (affirming reasons), reasons for only the option not initially chosen (opposing reasons), or reasons for both options. Although participants were more likely to change their initial decisions when presented with only opposing reasons compared with only affirming reasons, these effect sizes were consistently small. After evaluating reasons, participants were significantly more likely not to change their initial decisions than to change them, regardless of the set of reasons they considered. The initial decision accounted for most of the variance in predicting the final decision, whereas the reasons evaluated accounted for a relatively small proportion of the variance in predicting the final decision. This resistance to changing moral decisions is at least partly attributable to a biased, motivated evaluation of the available reasons: participants rated the reasons supporting their initial decisions more favorably than the reasons opposing their initial decisions, regardless of the reported strategy used to make the initial decision. Overall, our results suggest that the consideration of reasons rarely induces people to change their initial decisions in moral dilemmas.

Mothers want extraversion over conscientiousness or intelligence for their children

Mothers want extraversion over conscientiousness or intelligence for their children. Rachel Latham & Sophie von Stumm. Personality and Individual Differences, Volume 119, Dec 01 2017, Pages 262-265, https://doi.org/10.1016/j.paid.2017.07.037

Highlights
•    We examined what traits mothers value as most important for their child to have.
•    Mothers valued extraversion as most important for their child.
•    Extraversion was preferred over intelligence and conscientiousness.

Abstract: Intelligence and conscientiousness are key predictors of all important life outcomes, such as socioeconomic success, marital status, health and longevity. It is unclear, however, if and to what extent lay people appreciate these dimensions of individual differences. Here, 142 mothers of 0–12 month old infants were asked to select from each of the Big Five personality traits the facets that they most liked their child to have. Afterwards, mothers rank-ordered the facets they had selected and ‘intelligence’ from most to least important for their child to have. Less than 10% of mothers rated intelligence and the conscientiousness facet as most important. By contrast, 51% rated the extraversion facet as most important, followed by 20% of mothers who favoured the agreeableness facet. Our results suggest that mothers preferred extraversion over intelligence and conscientiousness, despite their strong, empirically demonstrated predictive validity for important life outcomes.

Emission budgets and pathways consistent with limiting warming to 1.5 °C

Emission budgets and pathways consistent with limiting warming to 1.5 °C. Richard J. Millar et al. Nature Geoscience (2017), doi:10.1038/ngeo3031

Abstract: The Paris Agreement has opened debate on whether limiting warming to 1.5 °C is compatible with current emission pledges and warming of about 0.9 °C from the mid-nineteenth century to the present decade. We show that limiting cumulative post-2015 CO2 emissions to about 200 GtC would limit post-2015 warming to less than 0.6 °C in 66% of Earth system model members of the CMIP5 ensemble with no mitigation of other climate drivers, increasing to 240 GtC with ambitious non-CO2 mitigation. We combine a simple climate–carbon-cycle model with estimated ranges for key climate system properties from the IPCC Fifth Assessment Report. Assuming emissions peak and decline to below current levels by 2030, and continue thereafter on a much steeper decline, which would be historically unprecedented but consistent with a standard ambitious mitigation scenario (RCP2.6), results in a likely range of peak warming of 1.2–2.0 °C above the mid-nineteenth century. If CO2 emissions are continuously adjusted over time to limit 2100 warming to 1.5 °C, with ambitious non-CO2 mitigation, net future cumulative CO2 emissions are unlikely to prove less than 250 GtC and unlikely greater than 540 GtC. Hence, limiting warming to 1.5 °C is not yet a geophysical impossibility, but is likely to require delivery on strengthened pledges for 2030 followed by challengingly deep and rapid mitigation. Strengthening near-term emissions reductions would hedge against a high climate response or subsequent reduction rates proving economically, technically or politically unfeasible.

“No one wants to be seen as someone who can’t afford to get online.”

Facebook Faces a New World as Officials Rein In a Wild Web. By PAUL MOZUR, MARK SCOTT and MIKE ISAAC. TNYT, Sept 17, 2017. https://www.nytimes.com/2017/09/17/technology/facebook-government-regulations.html


Facebook expanded its efforts in [Kenya,] country of 48 million in 2014. It teamed up with Airtel Africa, a mobile operator, to roll out Facebook’s Free Basics — a no-fee version of the social network, with access to certain news, health, job and other services there and in more than 20 other countries worldwide. In Kenya, the average person has a budget of just 30 cents a day to spend on internet access.

Free Basics now lets Kenyans use Facebook and its Messenger service at no cost, as well as read news from a Kenyan newspaper and view information about public health programs. Joe Mucheru, Kenya’s tech minister, said it at least gives his countrymen a degree of internet access.

Still, Facebook’s plans have not always worked out. Many Kenyans with access to Free Basics rely on it only as a backup when their existing smartphone credit runs out.

“Free Basics? I don’t really use it that often,” said Victor Odinga, 27, an accountant in downtown Nairobi. “No one wants to be seen as someone who can’t afford to get online.”

Encouraging consumers to take photos of sentimental possessions before donating them increases donations

Karen Page Winterich, Rebecca Walker Reczek, and Julie R. Irwin (2017) Keeping the Memory but Not the Possession: Memory Preservation Mitigates Identity Loss from Product Disposition. Journal of Marketing: September 2017, Vol. 81, No. 5, pp. 104-120. https://doi.org/10.1509/jm.16.0311

Abstract: Nonprofit firms' reliance on donations to build inventory distinguishes them from traditional retailers. This reliance on consumer donations means that these organizations face an inherently more volatile supply chain than retailers that source inventory from manufacturers. The authors propose that consumer reluctance to part with possessions with sentimental value causes a bottleneck in the donation process. The goal of this research is therefore to provide nonprofits with tools to increase donations of used goods and provide a theoretical link between the literature streams on prosocial behavior, disposition, memory, and identity. As such, the authors explore the effectiveness of memory preservation strategies (e.g., taking a photo of a good before donating it) in increasing donations to nonprofits. A field study using a donation drive demonstrates that encouraging consumers to take photos of sentimental possessions before donating them increases donations, and five laboratory experiments explicate this result by mapping the proposed psychological process behind the success of memory preservation techniques. Specifically, these techniques operate by ameliorating consumers' perceived identity loss when considering donation of sentimental goods.

Propensity for self-employment and success increase with ability balance

All About Balance? A Test of the Jack-of-all-Trades Theory Using Military Enlistment Data. Lina Aldén, Mats Hammarstedt, and Emma Neuman. Labour Economics. https://doi.org/10.1016/j.labeco.2017.09.001

Highlights
•    We test the Jack-of-all-trades theory using Swedish military enlistment data
•    Ability balance is measured based on tests of cognitive and non-cognitive ability
•    The unique data addresses the issue of endogeneity in skill balance
•    We find that both propensity for self-employment and success increase with ability balance
•    Policies for skill-building in many areas should encourage self-employment

Abstract: According to the Jack-of-all-trades theory, people with a balanced set of skills are more suitable for self-employment than are those without. In this paper we test this theory using Swedish Military Enlistment data. This data enables us to construct a measure of balance in abilities that, in comparison to measures used in previous research, is less contaminated by endogeneity problems. We find clear support for the Jack-of-all-trades theory, in the sense that the likelihood of being self-employed is higher for individuals whose skills are balanced. In addition, their earnings from self-employment tend to be higher.

The Evolutionary Psychology of Envy and Jealousy

The Evolutionary Psychology of Envy and Jealousy. Vilayanur S. Ramachandran and Baland Jalal. Front. Psychol., 19 September 2017 | https://doi.org/10.3389/fpsyg.2017.01619

Abstract: The old dogma has always been that the most complex aspects of human emotions are driven by culture; Germans and English are thought to be straight-laced whereas Italians and Indians are effusive. Yet in the last two decades there has been a growing realization that even though culture plays a major role in the final expression of human nature, there must be a basic scaffolding specified by genes. While this is recognized to be true for simple emotions like anger, fear, and joy, the relevance of evolutionary arguments for more complex nuances of emotion have been inadequately explored. In this paper, we consider envy or jealousy as an example; the feeling evoked when someone is better off than you. Our approach is broadly consistent with traditional evolutionary psychology (EP) approaches, but takes it further by exploring the complexity and functional logic of the emotion – and the precise social triggers that elicit them – by using deliberately farfetched, and contrived “thought experiments” that the subject is asked to participate in. When common sense (e.g., we should be jealous of Bill Gates – not of our slightly richer neighbor) appears to contradict observed behavior (i.e., we are more envious of our neighbor) the paradox can often be resolved by evolutionary considerations which predict the latter. Many – but not all – EP approaches fail because evolution and common sense do not make contradictory predictions. Finally, we briefly raise the possibility that gaining deeper insight into the evolutionary origins of certain undesirable emotions or behaviors can help shake them off, and may therefore have therapeutic utility. Such an approach would complement current therapies (such as cognitive behavior therapies, psychoanalysis, psychopharmacologies, and hypnotherapy), rather than negate them.

(3) Let us say I were to prove by brain scans or some other reliable measure (e.g., mood/affect inventory) that (A) the Dalai Lama was vastly happier on some abstract, but very real, scale than (B) someone (say Hugh Heffner) who has limitless access to attractive women. Who are you more envious of?

Most men are more envious of the latter (9 out of 9 males we surveyed chose B). In other words, you are more jealous of what the other person has access to (in relation to what you desire), than of the final overall state of joy and happiness. This is true even though common sense might dictate the opposite. Put differently, evolution has programmed into you an emotion (jealousy) that is triggered by certain very specific “releasers” or social cues; it is largely insensitive to what the other person’s final state of happiness is. The final state of happiness is too abstract to have evolved as a trigger of envy or jealousy.

For similar reasons, if you are starving it makes more sense that you would be more jealous (at least temporarily) of someone enjoying a fine meal than someone having sex with a beautiful woman or man. If you are only slightly hungry, however, you might pick sex. This is because there is an unconscious metric in your brain that computes the probability of finding food in the near future vs. finding a nubile, available mate; and of the urgency of your need for food over the urgency of mating. If you are starving to death and have one last fling, you have only that single mating opportunity whereas if you eat and live you will have plenty of mating opportunities in the future.

Higher USA State Resident Neuroticism Is Associated With Lower State Volunteering Rates

Higher USA State Resident Neuroticism Is Associated With Lower State Volunteering Rates. Stewart McCann. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167217724802

Abstract: Highly neurotic persons have dispositional characteristics that tend to precipitate social anxiety that discourages formal volunteering. With the 50 American states as analytical units, Study 1 found that state resident neuroticism correlated highly (r = -.55) with state volunteering rates and accounted for another 26.8% of the volunteering rate variance with selected state demographics controlled. Study 2 replicated Study 1 during another period and extended the association to college student, senior, secular, and religious volunteering rates. Study 3 showed state resident percentages engaged in other social behaviors involving more familiarity and fewer demands than formal volunteering related to state volunteering rates but not to neuroticism. In Study 4, state resident neuroticism largely accounted statistically for relations between state volunteering rates and state population density, collectivism, social capital, Republican preference, and well-being. This research is the first to show that state resident neuroticism is a potent predictor of state volunteering rates.

Outrage-inducing content appears to be more prevalent and potent online than offline

Moral outrage in the digital age. M. J. Crockett. Nature Human Behaviour (2017). doi:10.1038/s41562-017-0213-3

Moral outrage is a powerful  emotion that motivates people to shame and punish wrongdoers. Moralistic punishment can be a force for good, increasing cooperation by holding bad actors accountable. But punishment also has a dark side — it can exacerbate social conflict by dehumanizing others  and escalating into destructive feuds.

Moral outrage is at least as old as civilization itself, but civilization is rapidly changing in the face of new technologies. Worldwide, more than a billion people now spend at least an hour a day on social media, and moral outrage is all the rage online. In recent years, viral online shaming has cost
companies millions, candidates elections, and individuals their careers overnight.

As digital media infiltrates our social lives, it is crucial that we understand how this technology might transform the expression of moral outrage and its social consequences. Here, I describe a simple psychological framework for tackling this question (Fig. 1). Moral outrage is triggered by stimuli that call attention to moral norm violations. These stimuli evoke a range of emotional and behavioural responses that vary in their costs and constraints. Finally, expressing outrage leads to a variety of personal and social outcomes. This framework reveals that digital media may exacerbate the expression of moral outrage by inflating its triggering stimuli, reducing some of its costs and amplifying many of its personal benefits.

---
If moral outrage is a fire, is the internet like gasoline? Technology companies have argued that their products provide neutral platforms for social behaviours but do not change those behaviours. This is an empirical question that behavioural scientists should address, because its answer has ethical and regulatory implications.

The framework proposed here offers a set of testable hypotheses about the impact of digital media on the expression of moral outrage and its social consequences. Digital media may promote the expression of moral outrage by magnifying its triggers, reducing its personal costs and amplifying its personal benefits. At the same time, online social networks may diminish the social benefits of outrage by reducing the likelihood that norm-enforcing messages reach their targets, and could even impose new social costs by increasing polarization.

Preliminary data support the framework’s predictions, showing that outrage-inducing content appears to be more prevalent and potent online than offline. Future studies should investigate the extent to which digital media platforms intensify moral emotions, promote habit formation, suppress productive social discourse, and change the nature of moral outrage itself. There are vast troves of data that are directly pertinent to these questions, but not all of it is publicly available. These data can and should be used to understand how new technologies might transform ancient social emotions from a force for collective good into a tool for collective self-destruction.

Cognitive Resources in the Service of Identity Expression

An Expressive Utility Account of Partisan Cue Receptivity: Cognitive Resources in the Service of Identity Expression. Yphtach Lelkes, Ariel Malka, and Bert N. Bakker. https://www.dropbox.com/s/gbw56kdk8d0aoa1/expressivecues.pdf

Abstract: What motivates citizens to rely on partisan cues when forming political judgments? Extant literature offers two perspectives on this matter: an optimistic view that reliance on cues serves to enable adequate decision making when cognitive resources are low, and a pessimistic view that reliance on cues serves to channel cognitive resources to the goal of expressing valued political identities. In the present research we seek to further understanding of the relative importance of these two motives. We find that individuals low in cognitive resources are not more likely to follow partisan cues than are individuals high in cognitive resources. Furthermore, we find the highest level of cue receptivity is observed for those individuals who have both a strong social identification with their party and high cognitive resources. This suggests that partisan cue receptivity more often involves a harnessing of cognitive resources for the goal of identity expression.

Keywords: Partisan Cues, Social Identity, Cognitive Reflection, Motivated Reasoning

This work complements and extends two recent projects on the role of reflection on political reasoning. First, Arceneaux and Vander Wielen (2017) argue that those who are the least likely to be affectively attached to issues or parties and the most likely to be reflective exhibit behavior most akin to democratic ideals. In particular, these low affect/high reflection citizens are less likely to conform to elite cues than those who are high in affect and low in reflection. This is because these citizens combine relative weak emotional attachments to party-consistent issue positions with a relatively strong tendency to engage in effortful reasoning that could override emotional intuitions. As our strength of party identity measures affective attachment to a party (Huddy et al., 2015), the present work investigates the effect of high affect/high reflection on political reasoning, and our results are in line with Arceneaux and Vander Wielen (2017) untested predictions which they suggest for future research. Specifically, strong cognitive resources combined with an emotional attachment to partisanship seems to lead to toeing the party line. Second, Groenendyk (2013) argues that cognitive resources are required to defend one’s partisan identity–one reason partisan identities may remain stable among those high in cognitive resources is because they are able to rationalize changing attitude structures. The present findings reinforce that perspective as well.

How the Presence of Others Affects Desirability Judgments in Heterosexual and Homosexual Participants

Scofield, John E, Bogdan Kostic, and Erin M Buchanan. 2017. “How the Presence of Others Affects Desirability Judgments in Heterosexual and Homosexual Participants”. Open Science Framework. September 17. www.osf.io/ej5kh.

Abstract: Mate-choice copying is a mating strategy wherein females rely on contextual information to assist in securing accurate assessments of potential mates. Mate-choice copying has been extensively studied in non-human species and has begun to be examined in humans as well. Hill and Buss (2008) found evidence of opposing effects for men and women in desirability judgments based on the presence of other opposite-sex people. The current project successfully replicated Hill and Buss (2008), Experiment 1, finding support for the desirability enhancement effect and the desirability diminution effect. The current project also extended Hill and Buss, Experiment 1, to include homosexual participants. Homosexual men showed similar patterns as heterosexual women, and homosexual women showed similar patterns as heterosexual men, revealing differences across sexual orientation in human mate-choice copying.

The purpose of the current project was to replicate Hill and Buss (2008), Experiment 1 and to extend their findings to include homosexual populations. Hill and Buss found opposing sex differences while investigating the presence of others on judgments of desirability. Hill and Buss found evidence for the desirability enhancement effect, in which females rated male targets surrounded by females as more desirable compared to those same males surrounded by other males. Desirability judgments had the opposite effect on male participants, known as the desirability diminution effect. Male participants rated target females as less desirable when surrounded by males, compared to when those same females were surrounded by other females.

Females were suggested to employ mate-choice copying mating tactics, such as social information provided in stimulus photographs when making mate assessments. In evolutionary theory, females may take into consideration the presence of other females, providing cues to the mate quality of males. Specifically, with females surrounding males, the mate quality of the male is assumed to be higher. Men were shown not to use typical mate-choice copying mating tactics. Males rated female targets surrounded by males as less desirable than when surrounded by other females or when alone. Males were suggested to assess potential mates with a probabilistic orientation, suggesting that the presence of other males in the scene hint at a decreased probability of gaining access to that mate, negatively influencing desirability judgments of that target female.

[...]

Results showed that homosexual male participants rated target males surrounded by females as more desirable compared to male targets surrounded by other males. Homosexual female participants, however, showed the opposite effect in that they rated target females less desirable when surrounded by males compared to when surrounded by females. This result is contrary to our predictions that heterosexual and homosexual judgments would both follow similar patterns, dictated per biological sex (regardless of sexual orientation). That is, homosexual and heterosexual men would both exhibit the desirability diminution effect, and both homosexual and heterosexual women would exhibit the desirability enhancement effect.
