Operationalization of Excessive Masturbation—Development of the Excessive Masturbation Scale (EMS)

Operationalization of Excessive Masturbation—Development of the EMS. Wiebke Driemeyer, Jan Snagowski, Christian Laier, Michael Schwarz & Matthias Brand. Sexual Addiction & Compulsivity, Volume 25, 2018 - Issue 2-3, Pages 197-215. https://doi.org/10.1080/10720162.2018.1495586 

Abstract: Research has recently focused on hypersexual behavior and Internet-pornography-viewing disorder as potential psychopathological conditions, but specific aspects of the phenomena have been widely neglected. This study aimed to investigate excessive masturbation as a subset and symptom of hypersexual behaviors. 2 studies with independent samples have been conducted. In study 1 (n = 146), the Excessive Masturbation Scale (EMS) was designed and tested via explorative factor analysis. In study 2 (n = 255), the psychometric properties of the EMS were evaluated by confirmatory factor analysis. A replicable 2-factor structure (“Coping” and “Loss of Control”) was identified. The EMS showed good psychometric properties and provides a promising basis for further research.

No, You Can’t Ignore Email. It’s Rude. Being overwhelmed is no excuse. It’s hard to be good at your job if you’re bad at responding to people.

No, You Can’t Ignore E-mail. It’s Rude. Adam Grant. TNYT Feb 15 2019, https://www.nytimes.com/2019/02/15/opinion/sunday/email-etiquette.html
Being overwhelmed is no excuse. It’s hard to be good at your job if you’re bad at responding to people.

I’m really sorry I didn’t say hi, make eye contact or acknowledge your presence in any way when you waved to me in the hallway the other day. It’s nothing personal. I just have too many people trying to greet me these days, and I can’t respond to everyone.

That sounds ridiculous, right? You would never snub a colleague trying to strike up a conversation. Yet when you ignore a personal email, that’s exactly what you’ve done: digital snubbery.

Yes, we’re all overwhelmed with email. One recent survey suggested that the average American’s inbox has 199 unread messages. But volume isn’t an excuse for not replying. Ignoring email is an act of incivility.

“I’m too busy to answer your email” really means “Your email is not a priority for me right now.” That’s a popular justification for neglecting your inbox: It’s full of other people’s priorities. But there’s a growing body of evidence that if you care about being good at your job, your inbox should be a priority.

When researchers compiled a huge database of the digital habits of teams at Microsoft, they found that the clearest warning sign of an ineffective manager was being slow to answer emails. Responding in a timely manner shows that you are conscientious — organized, dependable and hardworking. And that matters. In a comprehensive analysis of people in hundreds of occupations, conscientiousness was the single best personality predictor of job performance. (It turns out that people who are rude online tend to be rude offline, too.)

I’m not saying you have to answer every email. Your brain is not just sitting there waiting to be picked. If senders aren’t considerate enough to do their homework and ask a question you’re qualified to answer, you don’t owe them anything back.

How do you know if an email you’ve received — or even more important, one you’re considering writing — doesn’t deserve a response? After all, sending an inappropriate email can be as rude as ignoring a polite one.

I have a few general rules. You should not feel obliged to respond to strangers asking you to share their content on social media, introduce them to your more famous colleagues, spend hours advising them on something they’ve created or “jump on a call this afternoon.” If someone you barely know emails you a dozen times a month and is always asking you to do something for him, you can ignore those emails guilt-free.

Along these lines, the last time I made the mistake of admitting in this newspaper that I believe in being responsive to emails, I got a deluge of messages. One reader even wrote, “I just wanted to test you, to find out if it’s true.” So this time, let me be clear: I’m not writing this article as a personal note to your inbox, so it doesn’t require a personal reply to mine.

We all need to set boundaries. People shouldn’t be forced to answer endless emails outside work hours — which is why some companies have policies against checking emails on nights and weekends. Some people I know tell their colleagues they’ll be on email from 9 to 10 a.m. and 2 to 3 p.m. each day, but not in between. If it’s not an emergency, no one should expect you to respond right away.

Spending hours a day answering emails can stand in the way of getting other things done. One recent study shows that on days when managers face heavy email demands, they make less progress toward their goals and end up being less proactive in communicating their vision and setting expectations.

But that same study shows that email load takes a toll only if it’s not central to your job. And let’s face it: These days email is central to most jobs. What we really need to do is to make email something we think carefully about before sending, and therefore feel genuinely bad ignoring.

Whatever boundaries you choose, don’t abandon your inbox altogether. Not answering emails today is like refusing to take phone calls in the 1990s or ignoring letters in the 1950s. Email is not household clutter and you’re not Marie Kondo. Ping!

Your inbox isn’t just a list of other people’s tasks. It’s where other people help you do your job. It allows you to pose questions with a few keystrokes instead of spending the whole day on the phone, and it’s vital to gathering information that you can’t easily find in a Google search.

“My inbox is other people’s priorities” bothers me as a social scientist, but also as a human being. Your priorities should include other people and their priorities. It’s common courtesy to engage with people who are thoughtful in reaching out.

This isn’t just about doing unto others as you’d have them do unto you. Clearing out your inbox can jump-start your own productivity. One set of experiments showed that if you’re behind on a task, you’ll finish it faster if you’re busy, because you know you need to use your time efficiently. As a writer, I like to start the morning by answering a few emails — it helps me get into a productive rhythm of deep work. If you think you have too many emails, maybe you just don’t have enough.

Everyone occasionally misses an email. But if you’re habitually “too busy” to answer legitimate emails, there’s a problem with your process. It sends a signal that you’re disorganized — or that you just don’t care.

If you’re just hopelessly behind on your inbox, at least set up an auto-reply giving people another channel where they can reach you. A Slack channel. Twitter. A phone number. Post-it notes. Carrier pigeon.

Remember that a short reply is kinder and more professional than none at all. If you have too much on your plate, come clean: “I don’t have the bandwidth to add this.” If it’s not your expertise, just say so: “Sorry, this isn’t in my wheelhouse.” And if you want to say no, just say “no.”

We can all learn from the writer E.B. White, who, in response to a 1956 letter asking him to join a committee, responded with two short sentences. The first: a thank-you for the invitation. The second: “I must decline, for secret reasons.”

Post-truth, anti-truth, and ***can’t-handle-the-truth***: How responses to science are shaped by concerns about its impact

Sutton, Robbie & Petterson, Aino & T. Rutjens, Bastiaan. (2018). Post-truth, anti-truth, and can’t-handle-the-truth: how responses to science are shaped by concerns about its impact. https://www.researchgate.net/publication/327837926

Abstract: Science is valued for its basic and applied functions: producing knowledge and contributing to the common good. Much of the time, these are perceived to work in harmony. However, science is sometimes seen as capable of subverting the common good, by facilitating dangerous technologies (e.g., weapons of mass destruction) or exerting a malign influence on public policy, opinion, and behaviour. Employing the social functionalist framework of Tetlock (2002), we propose that efforts to censor and suppress scientific findings are motivated by concerns about their societal impact. We begin by covering recent political shifts towards more censorial and punitive responses to scientific research in the U.S. and elsewhere. We go on to propose that beyond traditional explanations of how people evaluate scientific findings, such as cognitive consistency motivations, people’s evaluations are shaped by perceptions of the potential societal impact of scientific data. Our recent studies have shown that independently of the extent to which scientific findings contradict people’s beliefs (as in the confirmation bias), people reject and oppose the publication, application, and funding of research to the extent that they judge its findings as threatening to the public interest. In the final part of the chapter, we outline avenues for further theory and research. Here, we particularly emphasize the importance of establishing whether concerns about impact are themselves rationalizations of opposition to research that are motivated by other moral concerns, such as perceived purity violations (Graham et al., 2009). Finally, we underline that it is crucial that further research examines perceptions of science as a dangerous force that must be neutralized, and the potential of these perceptions to obstruct not only the public understanding of scientific research, but ultimately, the research itself.

Reducing Discrimination with Reviews in the Sharing Economy: Evidence from Field Experiments on Airbnb

Cui, Ruomeng and Li, Jun and Zhang, Dennis, Reducing Discrimination with Reviews in the Sharing Economy: Evidence from Field Experiments on Airbnb (December 8, 2016). http://dx.doi.org/10.2139/ssrn.2882982

Abstract: Recent research has found widespread discrimination by hosts against guests of certain races in online marketplaces. In this paper, we explore ways to reduce such discrimination using online reputation systems. We conduct four randomized field experiments among 1,801 hosts on Airbnb by creating fictitious guest accounts and sending accommodation requests to them. We find that requests from guests with African American-sounding names are 19.2 percentage points less likely to be accepted than those with white-sounding names. However, a positive review posted on a guest's page significantly reduces discrimination: When guest accounts receive a positive review, the acceptance rates of guest accounts with white-sounding and African American-sounding names are statistically indistinguishable. We further show that a non-positive review and a blank review without any content can also help attenuate discrimination, but self-claimed information on tidiness and friendliness cannot reduce discrimination, which indicates the importance of encouraging credible peer-generated reviews. Our results offer direct and clear guidance for sharing-economy platforms to reduce discrimination.

Programming of Stress-Sensitive Neurons and Circuits by Early-Life Experiences

Programming of Stress-Sensitive Neurons and Circuits by Early-Life Experiences. Jessica L. Bolton et al. Front. Behav. Neurosci., Feb 18 2019. https://doi.org/10.3389/fnbeh.2019.00030

Abstract: Early-life experiences influence brain structure and function long-term, contributing to resilience or vulnerability to stress and stress-related disorders. Therefore, understanding the mechanisms by which early-life experiences program specific brain cells and circuits to shape life-long cognitive and emotional functions is crucial. We identify the population of corticotropin-releasing hormone (CRH)-expressing neurons in the hypothalamic paraventricular nucleus (PVN) as a key, early target of early-life experiences. Adverse experiences increase excitatory neurotransmission onto PVN CRH cells, whereas optimal experiences, such as augmented and predictable maternal care, reduce the number and function of glutamatergic inputs onto this cell population. Altered synaptic neurotransmission is sufficient to initiate large-scale, enduring epigenetic re-programming within CRH-expressing neurons, associated with stress resilience and additional cognitive and emotional outcomes. Thus, the mechanisms by which early-life experiences influence the brain provide tractable targets for intervention.

Exploring Sex Differences in the Neural Correlates of Self-and Other-Referential Gender Stereotyping

Exploring Sex Differences in the Neural Correlates of Self-and Other-Referential Gender Stereotyping. Jonas Hornung et al. Front. Behav. Neurosci., February 18 2019. https://doi.org/10.3389/fnbeh.2019.00031

While general self-referential processes and their neural underpinnings have been extensively investigated with neuroimaging tools, limited data is available on sex differences regarding self- and other-referential processing. To fill this gap, we measured 17 healthy women and men who performed a self- vs. other-appraisal task during functional magnetic resonance imaging (fMRI) using gender-stereotypical adjectives. During the self-appraisal task, typical male (e.g., “dominant,” “competitive”) and female adjectives (e.g., “communicative,” “sensitive”) were presented and participants were asked whether these adjectives applied to themselves. During the other-appraisal task, a prototypical male (Brad Pitt) and female actor (Julia Roberts) was presented and participants were asked again to judge whether typical male and female adjectives applied to these actors. Regarding self-referential processes, women ascribed significantly more female compared to male traits to themselves. At the same time both women and men indicated a stronger desire to exhibit male over female traits. While fMRI did not detect general sex differences in the self- and other-conditions, some subtle differences were revealed between the sexes: both in right putamen and bilateral amygdala stronger gender-congruent activation was found which was however not associated with behavioral measures like the number of self-ascribed female or male attributes. Furthermore, sex hormone levels showed some associations with brain activation pointing to a different pattern in women and men. Finally, the self- vs. other-condition in general led to stronger activation of the anterior cingulate cortex while the other- vs. self-condition activated the right precuneus more strongly which is in line with previous findings. To conclude, our data lend support for subtle sex differences during processing of stereotypical gender attributes. However, it remains unclear whether such differences have a behavioral relevance. We also point to several limitations of this study including the small sample size and the lack of control for potentially different hormonal states in women.

Self-identification as a pornography addict: examining the roles of pornography use, religiousness, and moral incongruence

Self-identification as a pornography addict: examining the roles of pornography use, religiousness, and moral incongruence. Joshua B. Grubbs, Jennifer T. Grant & Joel Engelman. Sexual Addiction & Compulsivity, Feb 07 2019. https://doi.org/10.1080/10720162.2019.1565848

Abstract: At present, the scientific community has not reached a consensus regarding whether or not people may be become addicted to or compulsive in use of pornography. Even so, a substantial number of people report feeling that their use of pornography is dysregulated or out of control. Whereas prior works considered self-reported feelings of addiction via indirect scales or dimensional measures, the present work examined what might lead someone to specifically identify as a pornography addict. Consistent with prior research, pre-registered hypotheses predicted that religiousness, moral disapproval, and average daily pornography use would emerge as consistent predictors of self-identification as a pornography addict. Four samples, involving adult pornography users (Sample 1, N = 829, Mage = 33.3; SD = 9.4; Sample 2, N = 424, Mage = 33.6; SD = 9.1; Sample 4, N = 736, Mage = 48.0; SD = 15.8) and undergraduates (Sample 3, N = 231, Mage = 19.3; SD = 1.8), were collected. Across all three samples, male gender, moral incongruence, and average daily pornography use consistently emerged as predictors of self-identification as a pornography addict. In contrast to prior literature indicating that moral incongruence and religiousness are the best predictors of self-reported feelings of addiction (measured dimensionally), results from all four samples indicated that male gender and average daily pornography use were the most strongly associated with self-identification as a pornography addict, although moral incongruence consistently emerged as a robust and unique predictors of such self-identification.

Effects of emotions on sexual behavior in men with and without hypersexuality: Findings lend support to conceptualizing HS behavior as a coping strategy for affective arousal

Effects of emotions on sexual behavior in men with and without hypersexuality. Michael H. Miner, Janna Dickenson & Eli Coleman. Sexual Addiction & Compulsivity, https://doi.org/10.1080/10720162.2018.1564408

Abstract: The association between positive and negative affect and sexual behavior in 39 MSM with and without hypersexuality (HS) was explored using ecological momentary assessment. Participants reported their current positive and negative affect three times per day and their sexual behavior each morning and evening. The relationship between affect and sexual behavior differed between men with or without HS. In those with HS, the timing of and interactions between experienced affect differentially predicted types of sexual behavior, indicating differing mechanisms driving partnered sexual behavior and masturbation. These findings lend support to conceptualizing HS behavior as a coping strategy for affective arousal.

---
Hypersexual behavior is characterized by intense, distressing, and recurrentsexual urges and fantasies that significantly interfere with a person’s dailyfunctioning (e.g., with personal, interpersonal, and occupational responsi-bilities). Hypersexual behavior is widely disputed with regard to conceptualization, etiology, and nomenclature, and has been dubbed such terms as “sexual addiction” (Carnes, 1983),“compulsive sexual behavior” (Coleman, 1991), “paraphilia related disorder” (Kafka & Prentky, 1997),“hypersexual disorder” (Kafka, 2010), and “out of control sexual behavior” (Braun-Harvey & Vigorito, 2015). Despite such disagreement, one of the hallmarksof all conceptualizations of hypersexuality (Carnes,1983,1991; Coleman, 1991, 2003; Kafka, 1997, 2010) is distress resulting from obsessive, compulsive, impulsive, and/or out of control sexual behavior (Black, Kehrberg, Flumerfelt, & Schlosser, 1997; Coleman et al., 2010; Dickenson, Gleason, Coleman, & Miner, 2018). Moreover, several theoretical models of hyper-sexual behavior indicate that engaging in sexual behavior functions as astrategy to cope with, escape from, or avoid unwanted emotions (Kafka, 2010; Reid & Kafka, 2014). Yet, to date, our understanding of how day-to-day changes in negative and positive affect are related to day-to-day changes in sexual behavior among men who exhibit hypersexual behavior remains limited.

Negative affect (e.g., sadness, fear) and mood (e.g., depressed, anxious) typically impede sexual interest and arousal (Bancroft et al., 2003a, 2003b), although some men have shown increases in sexual interest and arousalafter experiencing negative affect. Moreover, the link between negativeaffect and sexual behavior appears to vary across individuals. For example, men who have sex with men (MSM) show increased sexual risk behavior following anxious affective states, but only if they have low trait anxiety (Mustanski, 2007). Thus, negative affect can either augment or impede sexual interest, arousal, and behavior depending on additional traits of the individual. Perhaps the degree to which negative affect motivates sexual behavior is also different for men who vary in their tendency to exhibit hypersexual behavior.

Research has consistently demonstrated that men with hypersexual behav-ior exhibit emotion regulation difficulties. Many men with hypersexualbehavior exhibit high negative emotionality (Miner et al.,2016); negative emotional states related to their sexual behavior, such as shame, guilt, and hostility toward themselves (Reid, 2010); are more vulnerable to general lifestressors (Laier & Brand,2017); and have greater deficits in their ability to regulate emotions (Leppink, Chamberlain, Redden, & Grant, 2016; Rizor, Callands, Desrosiers, & Kershaw, 2017). Various theoretical models indicatethat hypersexual behavior serves to reduce unwanted emotions (Bancroft & Vukadinovic, 2004; Coleman, 1991). Such behavior initially provides relief, but this relief is temporary and ultimately leads to guilt and shame about engaging in problematic sexual behavior, thus, reentering the cycle.

Yet, the notion that the cycle of hypersexual behavior begins with negative emotionality has proven inconsistent. On one hand, research examining reports of reasons for engaging in sexual behavior has corroborated thehypothesized link between negative emotionality and sexual behavior. Some research has indicated that sexual behavior may be related to difficulties with negative affect regulation among hypersexual men, and hypersexualmen self-report that negative affect motivates sexual behavior (Parsonset al., 2008). Individuals who compulsively view pornography exhibited higher general stress levels, reported viewing sexual imagery for the purposes of sensation seeking or emotional avoidance, and showed an increasein positive affect immediately after viewing sexual imagery (Laier & Brand, 2017). Moreover, hypersexual MSM have reported that they engage in sexual behavior to cope with negative affect and gain a sense of affirmation and validation that they could not obtain from non-sexual social relationships,  whereas  MSM  without  hypersexual  behavior  did  not  (Parsonset al., 2008)

Other research has not substantiated the link between negative affect andsexual activity. Grov, Golub, Mustanski, and Parsons (2010) found that among MSM, daily negative affect was associated with decreased likelihood of partnered sexual activity that same day. Contrary to expectations and the above mentioned studies, men with and without HS did not differ in thedegree to which negative affect was associated with partnered sexual activity. Such inconsistent findings indicate that the role of affective regulation in pre-dicting sexual behavior is not clear and may involve the interaction of positive and negative affective changes.

Such contradictory results may be explained by differences in method-ology. Studies varied in their assessment of state versus trait levels of affect,the valence of the affective state (positive versus negative), assessment oftemporal versus concurrent effects (i.e., does affect lead to sexual behavior?), and assessment of whether the relationship between affective states(or traits) and sexual behavior differ between men with and without HS.To date, no study has examined whether the ways in which negative orpositive affect leads to a greater or lower likelihood of engaging in sexualbehavior differs among men with and without HS.

The current study aims to address this gap by examining the day-to-dayrelation between positive and negative affect and various types of sexualbehavior (viewing sexual imagery, engaging in masturbation and engagingin partnered sexual activity) using a sample of MSM with and without hypersexuality. By using Ecological Momentary Assessment (EMA: Dunton,Liao, Intille, Spruijt-Metz, & Pentz,2011; Shiffman, Stone, & Hufford,2008), we examined  temporal ordering of affect and sexual behavior. Thisstudy extends existing research by focusing on positive affect, as well asnegative affect, and by assessing masturbation and partnered sexual activity. Given prior research and proposed theoretical conceptualizations thathypersexual behavior serves as a coping strategy, we expected that negativeaffect will be associated with greater likelihood of engaging in all threetypes of sexual behavior among hypersexual men. Further, we expected thatpositive affect, but not negative affect, will be associated with greater likeli-hood of engaging in all three types of sexual behavior among MSM without hypersexuality.


Social discounting: A higher weight on future generations changes both climate and fiscal policy; absent fiscal policy adjustments, the social cost of carbon is not the optimal tax

Be careful what you calibrate for: Social discounting in general equilibrium. Lint Barrage. Journal of Public Economics, Volume 160, April 2018, Pages 33-49. https://doi.org/10.1016/j.jpubeco.2018.02.012

Highlights
•    Social discounting is assessed in a general equilibrium climate-economy model.
•    A higher weight on future generations changes both climate and fiscal policy.
•    Optimal policy includes an effective capital income subsidy.
•    Optimal policy includes labor-consumption wedge that is decreasing over time.
•    Absent fiscal policy adjustments, the social cost of carbon is not the optimal tax.

Abstract: Concerns about intergenerational equity have led to an influential practice of setting social utility discount rates based on ethical considerations rather than to match household behavior, particularly in climate change economics (e.g., Stern, 2006). This paper formalizes the broader policy implications of this approach in general equilibrium by characterizing jointly optimal environmental and fiscal policies in a climate-economy model with differential planner-household discounting. First, I show that decentralizing the optimal allocation requires not only high carbon prices but also fundamental changes to tax policy: If the government discounts the future less than households, implementing the optimal allocation requires an effective capital income subsidy (a negative intertemporal wedge), and, in a setting with distortionary taxation, an effective labor-consumption tax wedge that is decreasing over time. Second, if the government cannot subsidize capital income, the constrained-optimal carbon tax may be up to 50% below the present value of marginal damages (the social cost of carbon) due to the general equilibrium effects of climate policy on household savings. Third, given the choice to optimize either carbon, capital, or labor income taxes, the socially discounting planner's welfare ranking is ambiguous over a standard range of parameters. Overall, in general equilibrium, a policy-maker's choice to adopt differential social discounting may thus overturn conventional recommendations for both environmental and fiscal policy.

More frequent usage of Twitter positively affects the acquisition of current affairs knowledge; opposite is found for Facebook, particularly for citizens with less political interest

Social network sites and acquiring current affairs knowledge: The impact of Twitter and Facebook usage on learning about the news. Mark Boukes. Journal of Information Technology & Politics, Feb 06 2019. https://doi.org/10.1080/19331681.2019.1572568

Abstract: This study investigates how the use of Twitter and Facebook affects citizens’ knowledge acquisition, and whether this effect is conditional upon people’s political interest. Using a panel survey design with repeated measures of knowledge acquisition, this study is able to disentangle causality and to demonstrate that more frequent usage of Twitter positively affects the acquisition of current affairs knowledge. The opposite is found for Facebook: More frequent Facebook usage causes a decline in knowledge acquisition. This negative effect of Facebook usage occurred particularly for citizens with less political interest, thereby, amplifying the existing knowledge gap between politically interested and uninterested citizens.

KEYWORDS: Social network sites, learning effects, current affairs knowledge, Facebook, Twitter, social media, knowledge gap

To date, no research has been able to convincingly unveil a causal relationship between the usage of specific social networks sites and the acquisition of current affairs knowledge. This is partly due to the reliance on cross-sectional datasets. Survey research cannot determine the directionality of causal relationships: Associations between SNS usage and knowledge may identify a selection mechanism (i.e., knowledge causing SNS use) rather than a media effect. Using a panel survey design (three-waves; n = 3,240) with a repeated measure of (new) current affairs knowledge, the current study has a unique ability to analyze whether the two social networks most often used for news consumption (respectively Facebook and Twitter, [...]) affect the current affairs information that citizens acquire.

Judged originals (inaccurately) labeled as revisions to be superior to revisions (inaccurately) labeled as originals, or when revisions were trivial, incidental, non-existent, & even objectively worse than the original

Garcia-Rada, Ximena and John, Leslie K. and O'Brien, Ed and Norton, Michael I., The Revision Bias (February 4, 2019). Harvard Business School NOM Unit Working Paper No. 19-087. http://dx.doi.org/10.2139/ssrn.3329340

Abstract: Things change. Things also get changed—often. Why? The obvious reason is that revising things makes them better. In the current research, we document a less obvious reason: Revising things makes people think they are better, absent objective improvement. We refer to this phenomenon as the revision bias. Nine studies document this effect and provide insight into its psychological underpinnings. In Study 1, MBA students perceived their revised resumes to be of higher quality the more they differed from their original versions, but this perception was not justified: observers judged originals (inaccurately) labeled as revisions to be superior to revisions (inaccurately) labeled as originals. Study 2 pinpoints the direction of the effect: revisions are appealing, as opposed to originals being unappealing. Moreover, the revision bias holds in a variety of settings in which the revision is devoid of objective improvement: when revisions are trivial (Study 3A), incidental (Study 3B), non-existent (Study 3C), and even objectively worse than the original (Study 3D). Study 4 directly tests the self-fulfilling nature of the revision bias, testing whether mere revision framing leads people to become less critical of the experience—in this study, less sensitive to possible bugs while playing an otherwise identical “revised” video game—and whether this mediates the effect of revision framing on positive evaluations. Studies 5A and 5B offer further support by testing whether the revision bias is accentuated when people engage in a holistic processing style, whether measured as an individual difference (Study 5A) or experimentally induced (Study 5B).

Even though theories of dynamic equilibrium include phenomena of ruptures, homeostasis & tension, these are understood as momentary alterations of a condition that must be restored to maintain integrity

Affective semiosis and affective logic. Luca Tateo. New Ideas in Psychology, Volume 48, January 2018, Pages 1-11, https://doi.org/10.1016/j.newideapsych.2017.08.002

Abstract: Psychology values consistency, reduction of uncertainty, causality and continuity as normative aspects of mental life. Even though theories of dynamic equilibrium include phenomena of ruptures, homeostasis and tension as part of the psychological functioning, these are understood as momentary alterations of a condition that must be restored in order to maintain the integrity of the system. Yet in everyday life one can observe phenomena in which human beings constantly move ahead the conditions of living and the limits of what is somehow acceptable. Tension, ambivalence and uncertainty are part of existence and the most part of us can perfectly live with it, if not actively looking for it.

Traditional logic underneath psychology cannot account for this meaning-making process. We then need to think about a specific form of affective logic that can enable us to understand extreme phenomena not as pathologies but as special forms of meaning-making. I will outline an affective semiosis process based on an affective logic, drawing from the ideas of Peirce's semiotics, Meinong's theory of objectives, Wittegenstein's concept of “seeing-as”, Herbst's co-genetic logic and Simmel's complementarity between binding and unbinding.

According to Peirce, in his famous distinction between “seminars” and “laboratories” philosophers, the “true scientific Eros” (Peirce, CP 1.620)1 is not pursued by those who “love only the truth already in their possession and, thus, conceive their task as steadfast and uncompromising defense of their property” (Colapietro, 1988, p. xvii), rather by the “painstaking and cooperative inquirer” (Colapietro, 1988, p. xvii), who thinks that discover is an everending quest.

From 2018. The quiet virtues of sadness: A selective theoretical and interpretative appreciation of its potential contribution to wellbeing

The quiet virtues of sadness: A selective theoretical and interpretative appreciation of its potential contribution to wellbeing. Tim Lomas. New Ideas in Psychology, Volume 49, April 2018, Pages 18-26. https://doi.org/10.1016/j.newideapsych.2018.01.002

Abstract: Critical emotion theorists have raised concerns that “normal” human emotions like sadness are increasingly being pathologised as disorders. Counter efforts have consequently been made to normalise such emotions, such as by highlighting their ubiquity and appropriacy. This paper goes slightly further by suggesting that sadness may not merely be normal, but could have inherent value, and might even be an integral component of a flourishing life. It offers a selective theoretical and interpretative review of literature on the potential “virtues” of sadness. Three overarching themes are identified, each comprising four subthemes: (a) sadness as a mode of protection (including as a warning, as prompting disengagement, as a mode of conservation, and as enhancing accuracy); (b) sadness as an expression of care (including as a manifestation of love, of longing, of compassion, and eliciting care); and (c) sadness as a vehicle for flourishing (including as a moral sensibility, as engendering psychological development, as an aesthetic sensibility, and as integral to fulfilment). It is thus hoped that the paper can contribute to a more “positive” cultural discourse around sadness, suggesting that, for many people, experiences of sadness may serve an important function in their lives.

Prevalent practice in the literature of using correlated common and specific factors as independent predictors in classical ANOVA models is both statistically unsound and conceptually distorted

The misleading Dodo Bird verdict. How much of the outcome variance is explained by common and specific factors? Giulio de Felice et al. New Ideas in Psychology, Volume 54, August 2019, Pages 50-55. https://doi.org/10.1016/j.newideapsych.2019.01.006

Abstract: The literature on psychotherapy research makes use of the so-called "Dodo Bird Verdict" to show that therapeutic change owes more to common factors than to specific techniques. According to the bulk of the empirical literature, common factors explain 30–70% of therapy outcome variance, while specific factors account for between 5% and 15%. This formulation is based on the assumption that common and specific factors are independent of each other. The present study uses a systematic review of the literature to empirically demonstrate that common and specific factors of change are actually correlated. In other words, the prevalent practice in the literature of using correlated common and specific factors as independent predictors in classical ANOVA models is both statistically unsound and conceptually distorted. We offer several alternative proposals for a sensible re-evaluation of the Dodo Bird verdict.

Examining the effect of combat excitement & diminished civilian solidarity on life satisfaction for American veterans

Examining the effect of combat excitement & diminished civilian solidarity on life satisfaction for American veterans. Gary Senecal et al. New Ideas in Psychology, Volume 52, January 2019, Pages 12-17. https://doi.org/10.1016/j.newideapsych.2018.09.001

Abstract: The data accounting for the difficulties many OIF and OEF veterans experience upon reintegration into civilian society have been thoroughly documented over the last fifteen years. Among these difficulties, some veterans experience antisocial, self-injurious, and violent tendencies upon returning to civilian life. In this research project, 220 veterans were completed self-report surveys pertaining to their transition from military life to a civilian career. Some of the participants' responses revealed that there was a significant emotional and motivational dimension to the formation of otherwise aggressive and self-destructive tendencies activated upon leaving their military careers and culture. The term combat excitement was coined to articulate participants’ anticipation of enemy contact while deployed. This study demonstrates that high levels of combat excitement correlated with lower life satisfaction and lower civilian solidarity for participants in their civilian lives after leaving an active duty setting. Furthermore, civilians solidarity had a strong positive correlation with life satisfaction for participants. Ultimately, this study looks at how significant strong civilian relationships are vital to the health and life satisfaction of veterans as they leave active duty, as well as how combat excitement can weaken the tendency of veterans to have strong civilian relationships after service.

Social contents in dreams: Dreams were found to contain more social interactions than corresponding waking life; prosocial social simulations were not specifically aimed at familiar persons

Social contents in dreams: An empirical test of the Social Simulation Theory. Jarno Tuominen et al. Consciousness and Cognition, Volume 69, March 2019, Pages 133-145. https://doi.org/10.1016/j.concog.2019.01.017

Highlights
•    Hypotheses from the Social Simulation Theory of dreaming were tested.
•    A novel content analysis method, the Social Content Scale, was developed.
•    Dreams were found to contain more social interactions than corresponding waking life.
•    Prosocial social simulations were not specifically aimed at familiar persons.
•    REM and NREM reports did not differ in prosocial or aggressive interactions.

Abstract: Social Simulation Theory (SST) considers the function of dreaming to be the simulation of social events. The Sociality Bias and the Strengthening hypotheses of SST were tested. Social Content Scale (SCS) was developed to quantify social events. Additionally, we attempted to replicate a previous finding (McNamara et al., 2005, Psychological Science) of REM dreams as predisposed to aggressive, and NREM dreams to prosocial interactions.

Further, we investigated the frequency and quality of interactions in late vs early REM and NREM dreams. Data consisted of wake, REM and NREM home dream reports (N = 232, 116, 116, respectively) from 15 students. Dreams overrepresented social events compared to wake reports, supporting the Sociality Bias hypothesis. However, the Strengthening Hypothesis was not supported. We weren’t able to replicate the McNamara et al. finding, and no time of night effect was found. While SST gained partial support, further research on social contents in dreams is required.

High Socioeconomic Status Predicts Substance Use and Alcohol Consumption in U.S. Undergraduates; Asians & married students were the least likely to use alcohol & drugs

High Socioeconomic Status Predicts Substance Use and Alcohol Consumption in U.S. Undergraduates. Chris C. Martin. Substance Use & Misuse, Feb 15 2019. https://doi.org/10.1080/10826084.2018.1559193

Abstract: Background: In health sociology, the prevailing consensus is that socioeconomic status (SES) lowers illness risk. This model neglects the fact that unhealthful consumption patterns may covary with affluence. The current study examines consumption of drugs and alcohol among affluent U.S. college students.

Objectives: The article tests the hypothesis that undergraduate students from high-SES households have higher rates and levels of drug and alcohol consumption than their peers.

Methods: The study used self-report data from 18,611 18- to 24-year-old undergraduates across 23 public and private U.S. institutions from the Healthy Minds 2016 dataset. Results: I found that high-SES undergraduates were more likely than peers to use marijuana, choose varied drugs, consume alcohol frequently, and use alcohol and substances to cope with stress. The first three results were robust after controlling for gender, race, residence type, and relationship status. Marital status and race were stronger predictors than SES. Asians and married students were the least likely to use alcohol and drugs.

Conclusions/Importance: Findings supported the main hypotheses, and the effects were robust to controls. Consumption of illicit drugs and alcohol may be one hitherto neglected reason for downward mobility among economically privileged college students.

Telomere Length And Health Outcomes: Of 50 possible outcomes studied, only important for gastric cancer and, probably, diabetes and Alzheimer's disease

Telomere Length And Health Outcomes: An umbrella review of systematic reviews and meta-analyses of observational studies. Lee Smith et al. Ageing Research Reviews, https://doi.org/10.1016/j.arr.2019.02.003

Highlights
• Shorter telomere length are associated with higher risk of non-communicable disease.

• Until now no attempt has been made to capture the breadth of outcomes associated with telomere length.

• This review indicates that shorter telomere length has a highly suggestive association with incidence of only specific cancer types, and has suggestive evidence with diabetes and Alzheimer’s disease risks.

• Telomere length has a weak association with heightened risks in a range of other important health outcomes (n = 20), whereas it has no role with others, including 27 outcomes out of 50.


Abstract: The aim of the present study was to map and grade evidence for the relationships between telomere length with a diverse range of health outcomes, using an umbrella review of systematic reviews with meta-analyses. We searched for meta-analyses of observational studies reporting on the association of telomere length with any health outcome (clinical disease outcomes and intermediate traits). For each association, random-effects summary effect size, 95% confidence interval (CI), and 95% prediction interval were calculated. To evaluate the credibility of the identified evidence, we assessed also heterogeneity, evidence for small-study effect and evidence for excess significance bias. Twenty-one relevant meta-analyses were identified reporting on 50 different outcomes and including a total of 326 observational studies. The level of evidence was high only for the association of short telomeres with higher risk of gastric cancer in the general population (relative risk, RR = 1.95, 95%CI: 1.68-2.26), and moderate for the association of shorter telomeres with diabetes or with Alzheimer’s disease, even if limited to meta-analyses of case-control studies. There was weak evidence for twenty outcomes and not significant association for 27 health outcomes. The present umbrella review demonstrates that shorter telomere length may have an important role in incidence gastric cancer and, probably, diabetes and Alzheimer’s disease. At the same time, conversely to general assumptions, it does not find strong evidence supporting the notion that shorter telomere length plays an important role in many health outcomes that have been studied thus far.

Holding a green self-image & life satisfaction: Pro-environmental norms are experienced by greens as a standard of reference in the process of green status competition & by non-greens as a source of social pressure

Pro-environmental norms and subjective well-being: Panel evidence from the UK. Binder, Martin; Blankenberg, Ann-Kathrin; Welsch, Heinz; Oldenburg Discussion Papers in Economics V-417-19, 2019. https://www.econstor.eu/handle/10419/190962

Abstract: Tying in with a small number of studies on green norms, identity and subjective well-being, this paper studies the relationship between holding a green self-image and life satisfaction in the UK. Focusing on (sub-national) regions as the unit of reference, we investigate if and how the individual-level greenness-satisfaction relationship varies with measures of the prevalence and distribution (disparity) of greenness at the regional level, taking these measures as indicators of a green social norm. Two key findings emerge from our analysis. First, life satisfaction is negatively related to the regional-level mean (prevalence) and positively related to the regional-level diversity of greenness, while being unrelated to the degree of polarization of greenness. Taking the prevalence as a direct and diversity as an inverse measure of the validity of a greenness norm, these results are consistent with the idea that the norm is experienced (by greens) as a standard of reference in the process of green status competition or (by non-greens) as a source of social pressure. Second, the well-being benefits from holding a greener self-image are unrelated to the prevalence and diversity of greenness, but positively related to the polarization of greenness for those either very green or not green at all. This is consistent with the idea that green self-image yields well-being benefits through identity, that is, by identifying with the own group and differentiating oneself from other groups - a possibility that relies on sufficiently large differentiation/polarization of groups. We discuss differences between these results and previous findings based on measures of nation-wide prevalence and disparity of greenness.

Females preferred fungus‐infected males over other males; maybe these males invested their energetic resources to increase their attractiveness at the risk of survival, in a terminal investment fashion

Female choice for sick males over healthy males: Consequences for offspring. Alicia Reyes‐Ramirez et al. Ethology, Feb 15 2019, https://doi.org/10.1111/eth.12854

Abstract: Sexual selection theory indicates that ornament expression in males is in close relation to their condition. This “honesty” relationship serves as the basis for female choice: Females would mate with healthy males over sick males after assessing male ornament signal expression and derive benefits for their progeny. Here, we investigated female mate choice for infected and non‐infected males, male survival after infection (to corroborate the negative effect of infection), and fitness consequences of female preferences using Tenebrio molitor beetles. Male infection was produced having two types of challenges as follows: males infected with entomopathogenic fungi and males infected with nylon implants. Similar to previous studies, we corroborated that females preferred fungus‐infected males over positive control, negative control, and nylon‐challenged males. Survival was the lowest for fungus‐treated males followed by nylon‐treated and control males. Females mated with fungus‐treated males laid fewer and smaller eggs, and the laid eggs had less lipid content with a reduced eclosion success compared to females mated with non‐challenged males. Our interpretation is that fungus‐treated males invested their energetic resources to increase their attractiveness at the risk of survival, in a terminal investment fashion. Females, however, would have corrected their choice by investing less in their offspring.

Humor reduces the perceived veracity of proximal statements; diminishes the perceived veracity of negative disclosures; adding humor to negative disclosures boosts perceptions of warmth and competence

The impression management benefits of humorous self-disclosures: How humor influences perceptions of veracity. T. Bradford Bitterly et al. Organizational Behavior and Human Decision Processes, Volume 151, March 2019, Pages 73-89. https://doi.org/10.1016/j.obhdp.2019.01.005

Highlights
• Humor reduces the perceived veracity of proximal statements.
• Humor diminishes the perceived veracity of negative disclosures.
• Adding humor to negative disclosures boosts perceptions of warmth and competence.
• Humor is a powerful impression management tool.

Abstract: Across five studies, we identify humor as a powerful impression management tool that influences perceptions of veracity. In many domains, such as negotiations and interviews, individuals face a challenge with respect to disclosing negative information and managing impressions. For example, an interviewer may ask an applicant to name their greatest weakness. In these settings, disclosures that reveal negative information (e.g., “I am not good at math.”) can harm perceptions of warmth and competence. We demonstrate that pairing a humorous statement with a disclosure (e.g., “I am not good at math. Geometry is where I draw the line.”) changes perceptions of the veracity of the disclosure; disclosures are less likely to be judged as true when they are accompanied by a humorous statement than when they are not. We introduce the Speaker's Inferred Motive (SIM) Model and consider the possibility that (a) speakers pursue different motives, such as a transmission-of-ideas motive (to convey information) or an entertainment motive (to amuse an audience), (b) audience members infer the speaker’s motive, and (c) these inferences influence perceptions of the veracity of proximal disclosures. As a result, by using humor, a speaker may signal a shift in motive and diminish perceptions of the veracity of both the humorous statement and proximal claims. Taken together, when a target discloses negative information, including information that is highly relevant to the conversational partner, the use of humor can boost perceptions of warmth and competence. We discuss implications of our findings with respect to communication, interpersonal perception, and impression management.

We propose a novel tripartite taxonomy of Schadenfreude: Aggression, rivalry, and justice; the process of dehumanization may lie at the core of Schadenfreude

Schadenfreude deconstructed and reconstructed: A tripartite motivational model. Shensheng Wang, Scott O. Lilienfeld, Philippe Rochat. New Ideas in Psychology, Volume 52, January 2019, Pages 1-11. https://doi.org/10.1016/j.newideapsych.2018.09.002

Highlights
•    Research from diverse subdisciplines of psychology sheds light on Schadenfreude.
•    We propose a novel tripartite taxonomy of Schadenfreude: Aggression, rivalry, and justice.
•    The process of dehumanization may lie at the core of Schadenfreude.

Abstract: Schadenfreude is the distinctive pleasure people derive from others' misfortune. Research over the past three decades points to the multifaceted nature of Schadenfreude rooted in humans’ concerns for social justice, self-evaluation, and social identity. Less is known, however, regarding how the differing facets of Schadenfreude are interrelated and take shape in response to these concerns. To address these questions, we review extant theories in social psychology and draw upon evidence from developmental, personality, and clinical research literature to propose a novel, tripartite, taxonomy of Schadenfreude embedded in a motivational model. Our model posits that Schadenfreude comprises three separable but interrelated subforms (aggression, rivalry, and justice), which display different developmental trajectories and personality correlates. This model further posits that dehumanization plays a central role in both eliciting Schadenfreude and integrating its various facets. In closing, we point to fruitful directions for future research motivated by this novel account of Schadenfreude.

It challenges the use of cognitive-behavioural psychological models underpinning many of the dominant & popular accounts of emotion in the neurosciences; gives importance to the cultural-historical school

Emotions, social activity and neuroscience: The cultural-historical formation of emotion. Ian Burkitt. New Ideas in Psychology, Volume 54, August 2019, Pages 1-7. https://doi.org/10.1016/j.newideapsych.2018.11.001

Abstract: This article challenges the use of cognitive-behavioural psychological models underpinning many of the dominant and popular accounts of emotion in the neurosciences. Acknowledging that neurobiology is important for any understanding of emotion, an alternative model of neuropsychology is sought in the work of theorists of the cultural-historical school, particularly A. N. Leontyev and A. R. Luria. The importance of their work in stressing the key role of intentional social activity, culture, and language in the formation of human neuropsychological functions is developed into a theory of emotions that can provide an alternative for emotion studies. In this theory, activity, culture, history, and individual ontogeny play the defining role in structuring the neurobiological systems that underlie emotions, as opposed to the evolution of behaviours that are hard-wired into the brain and function as automatic responses. Instead, it is understood that there is a continuum between evolution and human social and cultural development.

On the relative preponderance of empathic sorrow and its relation to commonsense morality

On the relative preponderance of empathic sorrow and its relation to commonsense morality. Edward B. Royzman, Rahul Kumar. New Ideas in Psychology, Volume 19, Issue 2, August 2001, Pages 131-144. https://doi.org/10.1016/S0732-118X(00)00020-9

Abstract: Empathy is a nominally neutral term: in principle, the affective tone of empathic concern may be either negative (insofar as the relevant experience is that of apprehending and sharing in another's aversive state) or positive (i.e., apprehending and sharing in another's joy). Yet, we propose (Section 1) that, contrary to this standard conception of empathy as a potentially bivalent, generalized disposition towards emotional perspective-taking, in actuality, negative empathic responses, as a rule, (a) are more common, (b) are more differentiated, and (c) span a broader range of human relationships than their positive counterparts. Furthermore, we suggest that, barring certain types of privileged relationships, a failure to be empathetically aroused by another's good fortune is subject to far less severe (if any) social disapproval than the failure to share in another's aversive state. In Section 2, we posit that the negativity bias evident in the nature of our empathic concern may well be at the base of the negative–positive asymmetry found in the structure of commonsense morality, particularly as it expresses itself in the view that the furtherance of another's good has a greater moral claim on us in its negative form (e.g., the relief of suffering) than in its positive form (the promotion of “enjoyment”). We conclude by asking whether this moral (and the underlying empathic) asymmetry warrants our normative concern and we suggest that there are at least two reasons to think otherwise.

Large teams develop and small teams disrupt science and technology: Study of more than 65 million papers, patents and software products that span the period 1954–2014

Large teams develop and small teams disrupt science and technology. Lingfei Wu, Dashun Wang & James A. Evans. Nature (2019), https://www.nature.com/articles/s41586-019-0941-9

Abstract: One of the most universal trends in science and technology today is the growth of large teams in all areas, as solitary researchers and small teams diminish in prevalence1,2,3. Increases in team size have been attributed to the specialization of scientific activities3, improvements in communication technology4,5, or the complexity of modern problems that require interdisciplinary solutions6,7,8. This shift in team size raises the question of whether and how the character of the science and technology produced by large teams differs from that of small teams. Here we analyse more than 65 million papers, patents and software products that span the period 1954–2014, and demonstrate that across this period smaller teams have tended to disrupt science and technology with new ideas and opportunities, whereas larger teams have tended to develop existing ones. Work from larger teams builds on more-recent and popular developments, and attention to their work comes immediately. By contrast, contributions by smaller teams search more deeply into the past, are viewed as disruptive to science and technology and succeed further into the future—if at all. Observed differences between small and large teams are magnified for higher-impact work, with small teams known for disruptive work and large teams for developing work. Differences in topic and research design account for a small part of the relationship between team size and disruption; most of the effect occurs at the level of the individual, as people move between smaller and larger teams. These results demonstrate that both small and large teams are essential to a flourishing ecology of science and technology, and suggest that, to achieve this, science policies should aim to support a diversity of team sizes.

Refugees in Denmark between 1986-1998: Evidence for steeper returns to experience in big cities; an individual’s lifetime wage path depends strongly on placement in the country’s capital, Copenhagen

Fabian Eckert & Conor Walsh & Mads Hejlesen, 2018. "The Return to Big City Experience: Evidence from Danish Refugees," 2018 Meeting Papers 1214, Society for Economic Dynamics. https://ideas.repec.org/p/red/sed018/1214.html

Abstract: Using a random settlement policy for refugees in Denmark between 1986-1998, we provide evidence for steeper returns to experience in big cities. Exploiting exogenous variation in initial placement, we show that the slope of an individual’s lifetime wage path depends strongly on placement in the country’s capital, Copenhagen. Conditional on observables, settled refugees initially earn similar hourly wages across regions, but those placed in Copenhagen see their wages grow 0.63% faster than others with each year of experience they accumulate. We further show that this premium is driven by greater acquisition of experience at high-wage establishments, and differential sorting across occupations. Finally, to account for dynamic selection within the city, we develop and estimate a structural model of earnings dynamics.


When Evolution Works Against the Future: Disgust's Contributions to the Acceptance of New Food Technologies

When Evolution Works Against the Future: Disgust's Contributions to the Acceptance of New Food Technologies. Aisha Egolf, Christina Hartmann, Michael Siegrist. Risk Analysis, Feb 13 2019. https://doi.org/10.1111/risa.13279

Abstract: New food technologies have a high potential to transform the current resource‐consuming food system to a more efficient and sustainable one, but public acceptance of new food technologies is rather low. Such an avoidance might be maintained by a deeply preserved risk avoidance system called disgust. In an online survey, participants (N = 313) received information about a variety of new food technology applications (i.e., genetically modified meat/fish, edible nanotechnology coating film, nanotechnology food box, artificial meat/milk, and a synthetic food additive). Every new food technology application was rated according to the respondent's willingness to eat (WTE) it (i.e., acceptance), risk, benefit, and disgust perceptions. Furthermore, food disgust sensitivity was measured using the Food Disgust Scale. Overall, the WTE both gene‐technology applications and meat coated with an edible nanotechnology film were low and disgust responses toward all three applications were high. In full mediation models, food disgust sensitivity predicted the disgust response toward each new food technology application, which in turn influenced WTE them. Effects of disgust responses on the WTE a synthetic food additive were highest for and lowest for the edible nanotechnology coating film compared to the other technologies. Results indicate that direct disgust responses influence acceptance and risk and benefit perceptions of new food technologies. Beyond the discussion of this study, implications for future research and strategies to increase acceptance of new food technologies are discussed.

Asexual women were less likely to report masturbating for sexual pleasure or fun than their sexual counterparts, & asexual men were less likely to report masturbating for sexual pleasure than sexual men

Sexual Fantasy and Masturbation Among Asexual Individuals: An In-Depth Exploration. Morag A. Yule, Lori A. Brotto, Boris B. Gorzalka. Archives of Sexual Behavior, January 2017, Volume 46, Issue 1, pp 311–328. https://link.springer.com/article/10.1007%2Fs10508-016-0870-8

Abstract: Human asexuality is generally defined as a lack of sexual attraction. We used online questionnaires to investigate reasons for masturbation, and explored and compared the contents of sexual fantasies of asexual individuals (identified using the Asexual Identification Scale) with those of sexual individuals. A total of 351 asexual participants (292 women, 59 men) and 388 sexual participants (221 women, 167 men) participated. Asexual women were significantly less likely to masturbate than sexual women, sexual men, and asexual men. Asexual women were less likely to report masturbating for sexual pleasure or fun than their sexual counterparts, and asexual men were less likely to report masturbating for sexual pleasure than sexual men. Both asexual women and men were significantly more likely than sexual women and men to report that they had never had a sexual fantasy. Of those who have had a sexual fantasy, asexual women and men were significantly more likely to endorse the response “my fantasies do not involve other people” compared to sexual participants, and consistently scored each sexual fantasy on a questionnaire as being less sexually exciting than did sexual participants. When using an open-ended format, asexual participants were more likely to report having fantasies about sexual activities that did not involve themselves, and were less likely to fantasize about topics such as group sex, public sex, and having an affair. Interestingly, there was a large amount of overlap between sexual fantasies of asexual and sexual participants. Notably, both asexual and sexual participants (both men and women) were equally likely to fantasize about topics such as fetishes and BDSM.

People use algorithmic advice more than human advice; appreciate algorithmic advice despite blindness to algorithm’s process; that appreciation holds even as people underweight advice more generally

Algorithm appreciation: People prefer algorithmic to human judgment. Jennifer M.Logg, Julia A. Minson, Don A. Moore. Organizational Behavior and Human Decision Processes, Volume 151, March 2019, Pages 90-103, https://doi.org/10.1016/j.obhdp.2018.12.005

Highlights
•    We challenge prevailing idea that people prefer human to algorithmic judgment.
•    In head-to-head comparisons, people use algorithmic advice more than human advice.
•    We compare usage of advice using the continuous weighting of advice (WOA) measure.
•    People appreciate algorithmic advice despite blindness to algorithm’s process.
•    Algorithm appreciation holds even as people underweight advice more generally.

Abstract: Even though computational algorithms often outperform human judgment, received wisdom suggests that people may be skeptical of relying on them (Dawes, 1979). Counter to this notion, results from six experiments show that lay people adhere more to advice when they think it comes from an algorithm than from a person. People showed this effect, what we call algorithm appreciation, when making numeric estimates about a visual stimulus (Experiment 1A) and forecasts about the popularity of songs and romantic attraction (Experiments 1B and 1C). Yet, researchers predicted the opposite result (Experiment 1D). Algorithm appreciation persisted when advice appeared jointly or separately (Experiment 2). However, algorithm appreciation waned when: people chose between an algorithm’s estimate and their own (versus an external advisor’s; Experiment 3) and they had expertise in forecasting (Experiment 4). Paradoxically, experienced professionals, who make forecasts on a regular basis, relied less on algorithmic advice than lay people did, which hurt their accuracy. These results shed light on the important question of when people rely on algorithmic advice over advice from people and have implications for the use of “big data” and algorithmic advice it generates.



Extramarital guys classified in four classes: Loyal, confiding, deceptive, & unfaithful; individuals differed significantly in ways that are consistent with the investment model and attachment theory

Rodriguez, L., DiBello, A., Øverup, C., & Lin, H. (2018). A Latent Class Analysis Approach to Extradyadic Involvement. Journal of Relationships Research, 9, E7. doi:10.1017/jrr.2018.6

Abstract: Extradyadic involvement — emotional, romantic, or sexual involvement with another person outside of one's romantic relationship — may have serious personal and relational consequences. The current research examines extradyadic involvement in two samples of individuals in relationships and identifies subgroups of people based on their engagement in different types of extradyadic behaviour. To assess involvement in such behaviour, we created a new behavioural inventory intended to broaden the conceptualisation of types of extradyadic behaviours. Subgroups of individuals who engage in these behaviours were extracted using latent class analysis. Study 1 assessed undergraduate students in relationships (N = 339), and results revealed four classes of individuals: loyal, confiding, deceptive, and unfaithful. Follow-up tests demonstrated that these classes of individuals differed significantly in ways that are consistent with the investment model and attachment theory. Study 2 (N = 202) replicated the four-class solution, as well as the group differences in relationship functioning and attachment orientations. Results suggest theoretically consistent typologies of extradyadic behaviour that may be useful in differentiating deceptive behaviour in close relationships in a more precise way.

---
In contrast, a series of eight studies by DeWall and colleagues (2011) found no association between attachment anxiety and infidelity.Infidelitywasoperationalised in a variety of ways (e.g., attitudes toward infidelity, engagement in overt or physical extradyadic behaviours, interest in meeting alternative partners, a validated selfreport wherein participants rated how emotionally and physically intimate they had been with an alternative partner). This final method of operationalising infidelity most closely resembles the way the current study wished to define levels of extradyadic behaviour, but in DeWall et al. (2011), the ratings were summed to create a composite infidelity index after items showed high reliability. Considering the desire of anxiously attached individuals to feel close and connected to important others (e.g., DeWall et al., 2011), measuring a range of emotional extradyadic behaviours, and not just interest in or physical attraction to alternatives, may be more important for linking anxious attachment to infidelity. This may be why a robust set of studies supporting associations between avoidant attachment and infidelity (described below) did not find significant associations between anxious attachment and infidelity.

Research on attachment avoidance paints a clearerpicture, likely driven by avoidant individuals’ fear of intimacy and desire for more independence (Brennan et al., 1998). Avoidant individuals showed greater interest in alternatives and a greater propensity for infidelity — associations that were mediated by lower levels of relationship commitment (DeWall et al., 2011). Additional work has found associations between attachment avoidance and infidelity (Fish et al., 2012) and that avoidant individuals reported the highest number of extradyadic partners compared with both anxious and secure individuals (Allen & Baucom, 2004). Thus, greater attachment avoidance may be associated with a higher likelihood of engaging in behaviours of sexual infidelity, such as kissing, heavy petting and sexual intercourse, particularly in more casual situations (Feeney, Noller, & Patty, 1993; Fraley, Davis, & Shaver, 1998). Moreover, attachment avoidance might also be associated with the greater use of deceptive extradyadic behaviours, as avoidantly attached individualstendtodislikeconflict(Domingue&Mollen, 2009). Using deception may be a way to avoid potential conflict situations with partners and maintain emotional and general independence. In contrast, Russell et al.’s (2013) longitudinal studies on newlywed couples found no association between one’s own attachment avoidance and infidelity; however, in one of the two studies, a partner effect of attachment avoidance on infidelity emerged, where one was less likely to cheat if his or her partner was higher in avoidance. These studies, which ran for three to four years, asked both spouses to report on their own perpetrated infidelity or discovery of their partner’s infidelity at each time point, with the definition of infidelity being left open to each participant.

Men's relationship satisfaction, passionate love, & liking were more driven by touch, whereas those of women's were more driven by hearing; higher differential valuing predicted higher passionate love for both

Miron, A., Jiang, L., Weisensel, K., Patterson, M., & Rizo, F. (2018). Testing a Transactional Model of Romantic Sensory Interactions in Male and Female Romantic Intimates. Journal of Relationships Research 2018, 9, e2. doi:10.1017/jrr.2018.2

Abstract: We propose a transactional model of romantic sensory interactions, according to which male and female intimates adapt to the specific context of their romantic relationships by adopting different sensory domains of interactions with their partners. To test this model, we measured romantic couples’ orientations toward using sensory modalities of romantic relating, and the importance of these modalities (N = 137 couples). Although not all hypotheses were supported, the findings suggest that men's relationship satisfaction, passionate love, and liking were driven by a stronger orientation toward touch, whereas women's relationship satisfaction, passionate love, liking, and commitment were predicted by a stronger preference for hearing. Higher differential valuing of touch and bodily sensations predicted higher passionate love for both men and women, suggesting that these sensory modalities have similar functions for both genders — to maintain sexual desire and passionate love for the partner. These findings underscore the importance of romantic couples’ differential sensory orientations in maintaining satisfying relationships.

Ratcliffe: Europe "has green taxes that, at best, can be described as foolish as they are having the opposite effect to how they were intended"

INEOS's Sir Jim Ratcliffe’s Open Letter to the European Commission President Jean-Claude Juncker. Feb 2019, https://www.ineos.com/news/ineos-group/letter-to-the-european-commission-president-jean-claude-juncker

Dear President Juncker,

“Are you quite mad?” was the reaction of one well known CEO of a European chemicals company when INEOS publicly announced recently its huge €3 billion petrochemicals expansion in Antwerp in January of this year.   The first of its kind for a generation.

Nobody but nobody in my business seriously invests in Europe.   They haven’t for a generation.   Everyone in my business does however invest in the USA, Middle East or China, or indeed, all three.   The USA is in the middle of a $200 billion spending spree on 333 new chemical plants.   China has spent that sum annually for many years, constructing its own chemical building blocks.

Europe, not so long ago the world leader in chemicals, has seen its market share in the last decade alone collapse from 30% world market share to 15%.   This is an industry that employs over 1 million people in high quality jobs in Europe and five times that in indirect jobs. Worldwide, chemicals is an immense industry, considerably bigger than the automotive sector with revenues approaching $4 trillion.

Europe is no longer competitive.   It has the worlds most expensive energy and labour laws that are uninviting for employers.   Worst of all, it has green taxes that, at best, can be described as foolish as they are having the opposite effect to how they were intended. 
Europe going it alone with green taxes prevents renewal as it frightens away investment into the open arms of the USA and China. It also pushes manufacturing to other parts of the world that care less for the environment. To get a sense of the importance of renewal a 70s car will emit 50 times the pollution of a modern day car. Chemical plants are not so different.
The USA is fully in the process of renewal.   Immense building programmes are installing the world’s finest chemical technology which has a fraction of the emissions we saw a generation ago.   Old units are being shut down.  The USA doesn’t have green taxes but it does insist on the very highest environmental standards before it issues permits for new builds.So let’s step back.  Europe remains with an industry built one or two generations ago with old environmental standards and has frightened away new investment for a generation with heavy green taxes.  America has welcomed new investment but on condition that it has the highest possible environmental standards.  It has created investment, new jobs and improved environmental emissions.  Europe has done the opposite on all fronts. I know who looks smarter.

I have an intense interest in preserving the environment.   I see wildlife being slaughtered in Africa, forests burning all over the world, fish stocks being decimated and I fully believe that we must arrest global warming.

But Europe ‘going it alone’ with green taxes as its main strategy has got it wrong.

As for the question posed to me at the outset, “Are we mad?”, the answer is no.   INEOS is uniquely able to import huge quantities of cheap energy and feedstocks from the USA and we have no ‘market risk’ as all the product that we will produce will be consumed by our own INEOS businesses in Europe.

But don’t expect others to follow.   They will be welcomed by the USA and China with a warm smile and a good strategy.

Europe, reminds me somewhat of the Charge of the Light Brigade, immortalised in Tennyson’s wonderful poem, full of valour and good intention but the outcome will not be pretty.

Yours Sincerely

Violent video game engagement is not associated with adolescents' aggressive behaviour: No evidence for a critical tipping point relating violent game engagement to aggressive behaviour

Violent video game engagement is not associated with adolescents' aggressive behaviour: evidence from a registered report. Andrew K. Przybylski and Netta Weinstein. Royal Society Open Science, Volume 6, Issue 2. https://doi.org/10.1098/rsos.171474

Abstract: In this study, we investigated the extent to which adolescents who spend time playing violent video games exhibit higher levels of aggressive behaviour when compared with those who do not. A large sample of British adolescent participants (n = 1004) aged 14 and 15 years and an equal number of their carers were interviewed. Young people provided reports of their recent gaming experiences. Further, the violent contents of these games were coded using official EU and US ratings, and carers provided evaluations of their adolescents' aggressive behaviours in the past month. Following a preregistered analysis plan, multiple regression analyses tested the hypothesis that recent violent game play is linearly and positively related to carer assessments of aggressive behaviour. Results did not support this prediction, nor did they support the idea that the relationship between these factors follows a nonlinear parabolic function. There was no evidence for a critical tipping point relating violent game engagement to aggressive behaviour. Sensitivity and exploratory analyses indicated these null effects extended across multiple operationalizations of violent game engagement and when the focus was on another behavioural outcome, namely, prosocial behaviour. The discussion presents an interpretation of this pattern of effects in terms of both the ongoing scientific and policy debates around violent video games, and emerging standards for robust evidence-based policy concerning young people's technology use.

Do Americans consider polling results an objective source of information? They view polls as more credible when majority opinion matched their opinion

All the Best Polls Agree with Me: Bias in Evaluations of Political Polling. Gabriel J. Madson. D. Sunshine Hillygus. Political Behavior, https://link.springer.com/article/10.1007/s11109-019-09532-1

Abstract: Do Americans consider polling results an objective source of information? Experts tend to evaluate the credibility of polls based on the survey methods used, vendor track record, and data transparency, but it is unclear if the public does the same. In two different experimental studies—one focusing on candidate evaluations in the 2016 U.S. election and one on a policy issue—we find a significant factor in respondent assessments of polling credibility to be the poll results themselves. Respondents viewed polls as more credible when majority opinion matched their opinion. Moreover, we find evidence of attitude polarization after viewing polling results, suggesting motivated reasoning in the evaluations of political polls. These findings indicate that evaluations of polls are biased by motivated reasoning and suggest that such biases could constrain the possible impact of polls on political decision making.

Sex Differences in Human Olfaction: A Meta-Analysis

Sex Differences in Human Olfaction: A Meta-Analysis. Piotr Sorokowski, Maciej Karwowski, Michał Misiak, Michalina Konstancja Marczak, Martyna Dziekan, Thomas Hummel and Agnieszka Sorokowska. Front. Psychol., 13 February 2019. https://doi.org/10.3389/fpsyg.2019.00242

Although the view that women's olfactory abilities outperform men's is taken for granted, some studies involving large samples suggested that male and female olfactory abilities are actually similar. To address this discrepancy, we conducted a meta-analysis of existing studies on olfaction, targeting possible sex differences. The analyzed sample comprised n = 8 848 (5 065 women and 3 783 men) for olfactory threshold (as measured with the Sniffin Sticks Test; SST), n = 8 067 (4 496 women and 3 571 men) for discrimination (SST), n = 13 670 (7 501 women and 6 169 men) for identification (SST), and a total sample of n = 7 154 (3 866 women and 3 288 men) for works using University of Pennsylvania Smell Identification Test (UPSIT). We conducted separate meta-analyses for each aspect of olfaction: identification, discrimination and threshold. The results of our meta-analysis indicate that women generally outperform men in olfactory abilities. What is more, they do so in every aspect of olfaction analyzed in the current study. However, the effect sizes were weak and ranged between g = 0.08 and g = 0.30. We discuss our findings in the context of factors that potentially shape sex differences in olfaction. Nevertheless, although our findings seem to confirm the “common knowledge” on female olfactory superiority, it needs to be emphasized that the effect sizes we observed were notably small.

High occupational level is associated with poor response to the treatment of depression

High occupational level is associated with poor response to the treatment of depression: A replication study. Laura Mandelli et al. European Neuropsychopharmacology, https://doi.org/10.1016/j.euroneuro.2019.01.107

Abstract

Major depressive disorder (MDD) is a leading cause of disability and inability to work. There is evidence that occupational factors may precipitate a MDD episode and interfere with the recovery process. In a previous investigation, we found that those employed in high occupational levels had a worse outcome after treatment for depression (Mandelli et al., 2016). The aim of the present study was to further investigate response to treatments for depression according to occupational status on an independent sample of MDD patients.

Six hundred and forty-seven (647) subjects with a stable working occupation were taken from a larger independent sample of MDD patients evaluated for response and resistance to treatment for depression, after at least one adequate treatment trial. Three broad occupational categories were considered: ‘manager’, ‘white-collar’, ‘blue-collar’ and ‘self-employed’.

Managers had the highest rate of non-response and resistance to treatments. White-collar workers also had high non-response and resistance rates. At the opposite, Blue-collar workers had significantly lower rates of non-response and resistance. Self-employed were in between White- and Blue-collar workers and did not significantly differ from the other occupational categories.

The findings of this replication study substantially support our previous observations. MDD patients employed in high-middle occupations may have a less favorable outcome after standard treatments of depression. Working stressful condition and other psychosocial factors at work should be investigated more closely in relation to treatment outcomes in MDD.


Consumers tend to consume too rapidly, growing tired of initially well-liked stimuli such as a favorite snack/an enjoyable video game more quickly than they would if they slowed consumption

Galak, Jeffrey; Kruger, Justin; Loewenstein, George (2018): Too Much of a Good Thing: Insensitivity to Rate of Consumption Leads to Unforeseen Satiation. https://kilthub.cmu.edu/articles/Too_Much_of_a_Good_Thing_Insensitivity_to_Rate_of_Consumption_Leads_to_Unforeseen_Satiation/6708902/1

Abstract: Consumers are often able to choose how often to consume the things they enjoy. The research presented here suggests that consumers tend to consume too rapidly, growing tired of initially well-liked stimuli such as a favorite snack (Experiments 1 and 4) or an enjoyable video game (Experiments 2 and 3) more quickly than they would if they slowed consumption. The results also suggest that this because of an underestimation of the extent to which breaks reset adaptation. The results present a paradox: Participants who chose their own rate of consumption enjoyed the stimulus less than participants who had a slower rate of consumption chosen for them.



Sovereign Bonds since Waterloo: The returns on external sovereign bonds have been sufficiently high to compensate for risk; & full repudiation is rare, the median haircut is below 50%

Sovereign Bonds since Waterloo. Josefin Meyer, Carmen M. Reinhart, Christoph TrebeschNBER Working Paper No. 25543, February 2019. https://www.nber.org/papers/w25543

Abstract: This paper studies external sovereign bonds as an asset class. We compile a new database of 220,000 monthly prices of foreign-currency government bonds traded in London and New York between 1815 (the Battle of Waterloo) and 2016, covering 91 countries. Our main insight is that, as in equity markets, the returns on external sovereign bonds have been sufficiently high to compensate for risk. Real ex-post returns averaged 7% annually across two centuries, including default episodes, major wars, and global crises. This represents an excess return of around 4% above US or UK government bonds, which is comparable to stocks and outperforms corporate bonds. The observed returns are hard to reconcile with canonical theoretical models and with the degree of credit risk in this market, as measured by historical default and recovery rates. Based on our archive of more than 300 sovereign debt restructurings since 1815, we show that full repudiation is rare; the median haircut is below 50%.
