Criminal energetics: A theory of antisocial enhancement and criminal attenuation. Michael G. Vaughn, Matt DeLisi. Aggression and Violent Behavior, https://doi.org/10.1016/j.avb.2017.11.002
Highlights
• The role of energy in shaping antisocial and criminal careers is examined.
• Energy is an enhancement and attenuator to an antisocial career.
• A set of future research pathways for studying energetics and criminality is presented.
Abstract: Although energy is the currency of all life forms and energy is an underlying factor for physical and mental performance, its role in antisocial behavior has yet to be articulated. In this paper, we consider the role of energy in shaping antisocial and criminal careers and suggest that much like other forms of performance/productivity some criminal offenders are more energetic and therefore more virulent than others over the life-course. Specifically, we argue that energy is an enhancement and attenuator to an antisocial career and draw upon a diverse literature merging basic research on aging and energy production in human physiology and merge these findings with principles from the career criminal paradigm in criminology. Finally, we lay forth a set of research pathways, especially ways in which energy can be assessed, that can forge stronger links between the science of energetics and criminality.

Callousness and manipulativeness are central traits to a dark personality
A Network of Dark Personality Traits: What Lies at the Heart of Darkness? David K. Marcus, Jonathan Preszler, Virgil Zeigler-Hill. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2017.11.003
Highlights
• Network analysis provides a novel approach to studying dark personality traits.
• Interpersonal manipulation is central to a network of dark personality traits.
• Callousness is central to a network of dark personality traits.
Abstract: The question of whether there is a common element at the core of the various dark personality traits (e.g., psychopathy, narcissism, Machiavellianism, spitefulness, aggressiveness) has been the subject of debate. Callousness, manipulativeness, and disagreeableness have all been nominated as possibly serving as the core of these dark traits. Network analysis, which graphically and quantitatively describes the centrality of various related traits, provides a novel technique for examining this issue. We estimated an association network and an Adaptive Least Absolute Shrinkage and Selection Operator network for two large samples, one college student sample (N = 2,831) and one mixed college student and Mechanical Turk sample (N = 844). Interpersonal manipulation and callousness were the traits that were central to the networks.

The “bad guy” profile is closer to the normal profile of real humans than that of the “good guys,” which are stereotyped
What are the cephalometric features of “good” and “bad” guys in cartoons? Alexandre Weiss, Cyril Villat, Alban Poitel and Sarah Gebeile-Chauty. Orthod Fr, Volume 88, Issue 3, 263 - 274.
https://doi.org/10.1051/orthodfr/2017015
Abstract
Objective: The objective of the study was to search for links between specific facial features and the psychology of the “good” and “bad” guys in cartoons. Material and method: We made 60 cephalometric tracings and compared the characters’ profiles using statistical tests.
Results: The “bad guy” profile is closer to the normal profile of real humans than that of the “good guys”. Profiles perceived as “good” in cartoons appear to be stereotyped. Thus, any profile not matching the “norm” can be interpreted as being unpleasant and consequently associated with the features of the “bad guys”. The standard “bad guy” profile has a longer more prominent nose, a jutting chin (a bigger soft-tissue angle) and a higher upper third of the face than the lower third (the opposite of the standard profile of the “good guys”).
Discussion: These standardized portraits reflect and influence the (subconscious) prejudices of both young and less young movie-goers (not to mention the cartoonists) regarding their fellow humans.

Violence Against Women Journal: The Meaning and Practice of Ejaculation on a Woman’s Face
Naked Aggression: The Meaning and Practice of Ejaculation on a Woman’s Face. Chyng Sun, Matthew B. Ezzell, Olivia Kendall. Violence Against Women, Vol 23, Issue 14, 2017. https://doi.org/10.1177/1077801216666723
Abstract: Based on in-depth interviews with 16 heterosexual men, this study focuses on participants’ meaning-making surrounding a common and controversial sexual act in pornography: ejaculation on a woman’s face (EOWF). We analyze the ways that male consumers decoded EOWF and the ways that EOWF, as a sexual script, was included in the men’s accounts of their sexual desires and practices. The majority of the men decoded EOWF through the preferred (encoded) meaning as an act of male dominance and sexual aggression and that they wanted to engage in it despite their general belief that women would not be interested in it.

Given that U.S. society is White supremacist, patriarchal, and capitalist (hooks, 1994), it is not surprising that pornographers would encode these values in sexual expression and gender dynamics that may also be familiar and even attractive to male consumers. Put simply, pornography reflects the hegemonic value of male dominance and further perpetuates it. Just as rape is both illegal and normalized within patriarchal cultures (see, for example, Buchwald, Fletcher, & Roth, 2004), male dominance and sexual aggression in pornography may be found simultaneously distasteful and enticing. Some of the men in our study were open and direct about the appeal of EOWF as an expression of male dominance, but others couched the appeal of the act in its role in “pushing boundaries” or in its status as “taboo,” even if they could articulate the preferred meaning upon reflection. The strategy of euphemizing male sexual aggression as “taboo” may allow respondents to eroticize it without feeling misogynistic—but this strategy has its contradictions.
Indeed, multiple contradictions were revealed in the respondents’ discourses around pornography and sex. Typically, male participants initially failed to articulate why they liked to watch EOWF in pornography or what meaning they saw, if any, in the act. But when they were allowed some time to reflect, they stated that it is about male dominance and female degradation. Most men acknowledged that female porn stars come from economically disadvantaged backgrounds and would only perform EOWF for money, but they also maintained that some performers genuinely liked it—and they maintained that they could tell—while saying that they often engaged in a “suspension of disbelief” to convince themselves of the performers’ enjoyment. Respondents also stated that they did not think women around them would like to be the targets of EOWF; nonetheless, they desired or had performed the act. This group of men seemed to struggle with cognitive dissonance (Aronson, 1992; Festinger, 1957; Stalder & Baron, 1998) concerning pornography’s function of providing sexual pleasure (in private, while masturbating) and the misogynistic messages that they were made aware of through self-reflection (in public, with an interviewer). The respondents’ lack of critical reflection, or their holding multiple, contradictory perspectives without resolving them, may be a form of moral identity work that allows them to maintain their stated attitude of “respecting women” while finding pleasure in male dominance. It is particularly at this juncture—recognizing the misogyny of EOWF but finding excuses to keep watching or performing it—that we recognize the power of pornography both in its encoded messages and in the context in which it is used.
[...]
Given that the subjects in the study were highly educated and had access to discourses of feminism and gender equality, the finding is particularly sobering.

Richard Feynman on Why Questions
[Transcript] Richard Feynman on Why Questions
I thought this video was a really good question dissolving by Richard Feynman. But it's in 240p! Nobody likes watching 240p videos. So I transcribed it. (Edit:
That was in jest. The real reasons are because I thought I could get
more exposure this way, and because a lot of people appreciate
transcripts. Also, Paul Graham speculates
that the written word is universally superior than the spoken word for
the purpose of ideas.) I was going to post it as a rationality quote,
but the transcript was sufficiently long that I think it warrants a
discussion post instead.
Here you go:
Here you go:
Interviewer: If you get hold of two magnets, and you push them, you can feel this pushing between them. Turn them around the other way, and they slam together. Now, what is it, the feeling between those two magnets?
Feynman: What do you mean, "What's the feeling between the two magnets?"
Interviewer: There's something there, isn't there? The sensation is that there's something there when you push these two magnets together.
Feynman: Listen to my question. What is the meaning when you say that there's a feeling? Of course you feel it. Now what do you want to know?
Interviewer: What I want to know is what's going on between these two bits of metal?
Feynman: They repel each other.
Interviewer: What does that mean, or why are they doing that, or how are they doing that? I think that's a perfectly reasonable question.
Feynman: Of course, it's an excellent question. But the problem, you see, when you ask why something happens, how does a person answer why something happens? For example, Aunt Minnie is in the hospital. Why? Because she went out, slipped on the ice, and broke her hip. That satisfies people. It satisfies, but it wouldn't satisfy someone who came from another planet and who knew nothing about why when you break your hip do you go to the hospital. How do you get to the hospital when the hip is broken? Well, because her husband, seeing that her hip was broken, called the hospital up and sent somebody to get her. All that is understood by people. And when you explain a why, you have to be in some framework that you allow something to be true. Otherwise, you're perpetually asking why. Why did the husband call up the hospital? Because the husband is interested in his wife's welfare. Not always, some husbands aren't interested in their wives' welfare when they're drunk, and they're angry.
And you begin to get a very interesting understanding of the world and all its complications. If you try to follow anything up, you go deeper and deeper in various directions. For example, if you go, "Why did she slip on the ice?" Well, ice is slippery. Everybody knows that, no problem. But you ask why is ice slippery? That's kinda curious. Ice is extremely slippery. It's very interesting. You say, how does it work? You could either say, "I'm satisfied that you've answered me. Ice is slippery; that explains it," or you could go on and say, "Why is ice slippery?" and then you're involved with something, because there aren't many things as slippery as ice. It's very hard to get greasy stuff, but that's sort of wet and slimy. But a solid that's so slippery? Because it is, in the case of ice, when you stand on it (they say) momentarily the pressure melts the ice a little bit so you get a sort of instantaneous water surface on which you're slipping. Why on ice and not on other things? Because water expands when it freezes, so the pressure tries to undo the expansion and melts it. It's capable of melting, but other substances get cracked when they're freezing, and when you push them they're satisfied to be solid.
Why does water expand when it freezes and other substances don't? I'm not answering your question, but I'm telling you how difficult the why question is. You have to know what it is that you're permitted to understand and allow to be understood and known, and what it is you're not. You'll notice, in this example, that the more I ask why, the deeper a thing is, the more interesting it gets. We could even go further and say, "Why did she fall down when she slipped?" It has to do with gravity, involves all the planets and everything else. Nevermind! It goes on and on. And when you're asked, for example, why two magnets repel, there are many different levels. It depends on whether you're a student of physics, or an ordinary person who doesn't know anything. If you're somebody who doesn't know anything at all about it, all I can say is the magnetic force makes them repel, and that you're feeling that force.
You say, "That's very strange, because I don't feel kind of force like that in other circumstances." When you turn them the other way, they attract. There's a very analogous force, electrical force, which is the same kind of a question, that's also very weird. But you're not at all disturbed by the fact that when you put your hand on a chair, it pushes you back. But we found out by looking at it that that's the same force, as a matter of fact (an electrical force, not magnetic exactly, in that case). But it's the same electric repulsions that are involved in keeping your finger away from the chair because it's electrical forces in minor and microscopic details. There's other forces involved, connected to electrical forces. It turns out that the magnetic and electrical force with which I wish to explain this repulsion in the first place is what ultimately is the deeper thing that we have to start with to explain many other things that everybody would just accept. You know you can't put your hand through the chair; that's taken for granted. But that you can't put your hand through the chair, when looked at more closely, why, involves the same repulsive forces that appear in magnets. The situation you then have to explain is why, in magnets, it goes over a bigger distance than ordinarily. There it has to do with the fact that in iron all the electrons are spinning in the same direction, they all get lined up, and they magnify the effect of the force 'til it's large enough, at a distance, that you can feel it. But it's a force which is present all the time and very common and is a basic force of almost - I mean, I could go a little further back if I went more technical - but on an early level I've just got to tell you that's going to be one of the things you'll just have to take as an element of the world: the existence of magnetic repulsion, or electrical attraction, magnetic attraction.
I can't explain that attraction in terms of anything else that's familiar to you. For example, if we said the magnets attract like if rubber bands, I would be cheating you. Because they're not connected by rubber bands. I'd soon be in trouble. And secondly, if you were curious enough, you'd ask me why rubber bands tend to pull back together again, and I would end up explaining that in terms of electrical forces, which are the very things that I'm trying to use the rubber bands to explain. So I have cheated very badly, you see. So I am not going to be able to give you an answer to why magnets attract each other except to tell you that they do. And to tell you that that's one of the elements in the world - there are electrical forces, magnetic forces, gravitational forces, and others, and those are some of the parts. If you were a student, I could go further. I could tell you that the magnetic forces are related to the electrical forces very intimately, that the relationship between the gravity forces and electrical forces remains unknown, and so on. But I really can't do a good job, any job, of explaining magnetic force in terms of something else you're more familiar with, because I don't understand it in terms of anything else that you're more familiar with.
Liking what others “Like”: using Facebook to identify determinants of conformity
Liking what others “Like”: using Facebook to identify determinants of conformity. Johan Egebark and Mathias Ekström. Experimental Economics, https://link.springer.com/article/10.1007/s10683-017-9552-1
Abstract: In this paper we explore the micro-level determinants of conformity. Members of the social networking service Facebook express positive support to content on the website by clicking a Like button. We set up a natural field experiment to test whether users are more prone to support content if someone else has done so before. To find out to what extent conformity depends on group size and social ties we use three different treatment conditions: (1) one stranger has Liked the content, (2) three strangers have Liked the content, and (3) a friend has Liked the content. The results show that one Like from a single stranger had no impact. However, increasing the size of the influencing group doubled the probability that subjects expressed positive support. Friendship ties were also decisive. People were, on average, four times more likely to press the Like button if a friend, rather than a stranger, had done so before them. The existence of threshold effects in our experiment clearly shows that both group size and social proximity matters when opinions are shaped.

Sexual Appeal Is In The Nose -- Patterns of Eye Movements When Observers Judge Female Facial Attractiveness
Patterns of Eye Movements When Observers Judge Female Facial Attractiveness. Yan Zhang et al. Front. Psychol., https://doi.org/10.3389/fpsyg.2017.01909
Abstract: The purpose of the present study is to explore the fixed model for the explicit judgments of attractiveness and infer which features are important to judge the facial attractiveness. Behavioral studies on the perceptual cues for female facial attractiveness implied three potentially important features: averageness, symmetry, and sexual dimorphy. However, these studies did not explained which regions of facial images influence the judgments of attractiveness. Therefore, the present research recorded the eye movements of 24 male participants and 19 female participants as they rated a series of 30 photographs of female facial attractiveness. Results demonstrated the following: (1) Fixation is longer and more frequent on the noses of female faces than on their eyes and mouths (no difference exists between the eyes and the mouth); (2) The average pupil diameter at the nose region is bigger than that at the eyes and mouth (no difference exists between the eyes and the mouth); (3) the number of fixations of male participants was significantly more than female participants. (4) Observers first fixate on the eyes and mouth (no difference exists between the eyes and the mouth) before fixating on the nose area. In general, participants attend predominantly to the nose to form attractiveness judgments. The results of this study add a new dimension to the existing literature on judgment of facial attractiveness. The major contribution of the present study is the finding that the area of the nose is vital in the judgment of facial attractiveness. This finding establish a contribution of partial processing on female facial attractiveness judgments during eye-tracking.

Same Genes, Different Brains: Neuroanatomical Differences Between Monozygotic Twins Discordant for Musical Training
Same Genes, Different Brains: Neuroanatomical Differences Between Monozygotic Twins Discordant for Musical Training. Örjan de Manzano Fredrik Ullén. Cerebral Cortex, https://doi.org/10.1093/cercor/bhx299
Abstract: Numerous cross-sectional and observational longitudinal studies show associations between expertise and regional brain anatomy. However, since these designs confound training with genetic predisposition, the causal role of training remains unclear. Here, we use a discordant monozygotic (identical) twin design to study expertise-dependent effects on neuroanatomy using musical training as model behavior, while essentially controlling for genetic factors and shared environment of upbringing. From a larger cohort of monozygotic twins, we were able to recruit 18 individuals (9 pairs) that were highly discordant for piano practice. We used structural and diffusion magnetic resonance imaging to analyze the auditory-motor network and within-pair differences in cortical thickness, cerebellar regional volumes and white-matter microstructure/fractional anisotropy. The analyses revealed that the musically active twins had greater cortical thickness in the auditory-motor network of the left hemisphere and more developed white matter microstructure in relevant tracts in both hemispheres and the corpus callosum. Furthermore, the volume of gray matter in the left cerebellar region of interest comprising lobules I–IV + V, was greater in the playing group. These findings provide the first clear support for that a significant portion of the differences in brain anatomy between experts and nonexperts depend on causal effects of training.

Zero Likes – Symbolic interactions and need satisfaction online
Zero Likes – Symbolic interactions and need satisfaction online. Sabine Reich, Frank M.Schneider, and Leonie Heling. Computers in Human Behavior, Volume 80, March 2018, Pages 97-102. https://doi.org/10.1016/j.chb.2017.10.043
Highlights
• Likes are a form of symbolic interaction within social networking sites (SNS).
• Zero Likes on SNS threaten fundamental needs and affect.
• Likes from close friends (vs. acquaintances) best satisfy fundamental needs.
Abstract: The paper looks at the symbolic interactions on social networking sites, such as Likes on Facebook, and their role in users' sense of social in- or exclusion. In an online experiment, users of Facebook were asked to write a possible status update and then received note about the numbers of hypothetical Likes they received (zero, two, or thirty) and who (close friends or acquaintances) pressed the Like button. Multivariate analysis of variances showed that belongingness and self-esteem needs are threatened when people do not receive Likes. In contrast, more Likes seem to satisfy these needs better. The influence of who gives the Likes is minor compared to the sheer number of Likes.

Paying Down Credit Card Debt for Hotels Not Sofas
Quispe-Torreblanca, Edika and Stewart, Neil and Gathergood, John and Loewenstein, George, The Red, the Black, and the Plastic: Paying Down Credit Card Debt for Hotels Not Sofas (September 15, 2017). Available at SSRN: https://ssrn.com/abstract=3037416
Abstract: Using transaction data from a sample of 1.8 million credit card accounts, we provide the first field test of a major prediction of Prelec and Loewenstein’s (1998) theory of mental accounting. The prediction is that consumers will pay off expenditure on transient forms of consumption more quickly than expenditure on durables. According to the theory, this is because the pain of paying can be offset by the future anticipated pleasure of consumption only when money is spent on consumption that endures over time. Consistent with the prediction, we found that repayment of debt incurred for non-durable goods is an absolute 9% more likely than repayment of debt incurred for durable goods. The size of this effect is comparable to an increment in 15 percentage points in the credit card APR.

Common sense in the New York Times: Many of our most demonized foods are actually fine for us. Like salt.
You Don’t Need to ‘Eat Clean’. By Aaron E. Carroll. The New York Times, November 5, 2017, Page SR10, https://www.nytimes.com/2017/11/04/opinion/sunday/relax-you-dont-need-to-eat-clean.html
We talk about food in the negative: What we shouldn’t eat, what we’ll regret later, what’s evil, dangerously tempting, unhealthy.
The effects are more insidious than any overindulgent amount of “bad food” can ever be. By fretting about food, we turn occasions for comfort and joy into sources of fear and anxiety. And when we avoid certain foods, we usually compensate by consuming too much of others.
All of this happens under the guise of science. But a closer look at the research behind our food fears shows that many of our most demonized foods are actually fine for us. Taken to extremes, of course, dietary choices can be harmful — but that logic cuts both ways.
Consider salt. It’s true that, if people with high blood pressure consume a lot of salt, it can lead to cardiovascular events like heart attacks. It’s also true that salt is overused in processed foods. But the average American consumes just over three grams of sodium per day, which is actually in the sweet spot for health.
Eating too little salt may be just as dangerous as eating too much. This is especially true for the majority of people who don’t have high blood pressure. Regardless, experts continue to push for lower recommendations.
Many of the doctors and nutritionists who recommend avoiding certain foods fail to properly explain the magnitude of their risks. In some studies, processed red meat in large amounts is associated with an increased relative risk of developing cancer. The absolute risk, however, is often quite small. If I ate an extra serving of bacon a day, every day, my lifetime risk of colon cancer would go up less than one-half of 1 percent. Even then, it’s debatable.
Nevertheless, we’ve become more and more susceptible to arguments that we must avoid certain foods completely. When one panic-du-jour wanes, we find another focus for our fears. We demonized fats. Then cholesterol. Then meat.
For some people in recent years, gluten has become the enemy, even though wheat accounts for about 20 percent of the calories consumed worldwide, more than pretty much any other food. Fewer than 1 percent of people in the United States have a wheat allergy, and fewer than 1 percent have celiac disease, an autoimmune disorder that requires sufferers to abstain from gluten. Gluten sensitivity (the catchall disorder that leads many Americans to abstain from gluten) is not well defined, and most people who self-diagnose don’t meet the criteria.
Nonetheless, at least one in five Americans regularly chooses gluten-free foods, according to a 2015 poll. Sales of products with gluten-free labels rose to $23 billion worldwide in 2014, up from $11.5 billion worldwide in 2010.
Gluten-free diets can lead to deficiencies in nutrients such as vitamin B, folate and iron. Compared with regular bagels, gluten-free ones can have a quarter more calories, two and a half times the fat, half the fiber and twice the sugar. They also cost more.
The hullabaloo over gluten echoes the panic over MSG that began roughly half a century ago, and which has yet to fully subside. MSG, or monosodium glutamate, is nothing more than a single sodium atom added to glutamic acid — an amino acid that is a key part of the mechanism by which our cells create energy. Without it, all oxygen-dependent life as we know it would die.
A 1968 letter in The New England Journal of Medicine started the frenzy; the writer reported feeling numbness, weakness and palpitations after eating at a Chinese restaurant. A few limited studies followed, along with a spate of news articles. Before long, nutrition experts and consumer advocates such as Ralph Nader were calling for MSG to be banned. The Food and Drug Administration never had to step in; food companies saw the writing on the wall, and dropped MSG voluntarily.
Many people still wrongly believe that MSG is poison. We certainly don’t need MSG in our diet, but we also don’t need to waste effort avoiding it. Our aversion to it shows how susceptible we are to misinterpreting scientific research and how slow we are to update our thinking when better research becomes available. There’s no evidence that people suffer disproportionately from the afflictions — now ranging from headaches to asthma — that MSG-averse cultures commonly associate with this ingredient. In studies all over the world, the case against MSG just doesn’t hold up.
Too often, we fail to think critically about scientific evidence. Genetically modified organisms are perhaps the best example of this.
G.M.O.s are, in theory, one of our best bets for feeding the planet’s growing population. When a 2015 Pew poll asked Americans whether they thought it was generally safe or unsafe to eat modified foods, almost 60 percent said it was unsafe. The same poll asked scientists from the American Association for the Advancement of Science the same question. Only 11 percent of them thought G.M.O.s were unsafe.
Most Americans, at least according to this poll, don’t seem to care what scientists think. In fact, Americans disagree with scientists on this issue more than just about any other, including a host of contentious topics such as vaccines, evolution and even global warming.
If people want to avoid foods, even if there’s no reason to, is that really a problem?
The answer is: yes. Because it makes food scary. And being afraid of food with no real reason is unscientific — part of the dangerous trend of anti-intellectualism that we confront in many places today.
Food should be a cause for pleasure, not panic. For most people, it’s entirely possible to eat more healthfully without living in terror or struggling to avoid certain foods altogether. If there’s one thing you should cut from your diet, it’s fear.

The differential impact of knowledge depth and knowledge breadth on creativity over individual careers
The differential impact of knowledge depth and knowledge breadth on creativity over individual careers. Pier Vittorio Mannucci and Kevyn Yong. Academy of Management Journal, http://amj.aom.org/content/early/2017/10/23/amj.2016.0529
Abstract: While usually argued to be fostering creativity, the effect of knowledge depth and breadth on creativity is actually mixed. We take a dynamic approach to the knowledge-creativity relationship and argue that the effect of knowledge depth and knowledge breadth is likely to be contingent on career age. We propose that individuals' knowledge structures become increasingly rigid as career age grows and that because of this, knowledge depth and breadth have different effects on creativity at different points of the career. More specifically, we hypothesize that knowledge depth is more beneficial for creativity in earlier stages of one's career, when creators need to increase the complexity of knowledge structures, while knowledge breadth is more beneficial in later stages, when flexibility is most needed. We test and find support for our hypotheses in a longitudinal study set in the context of the Hollywood animation industry, a setting characterized by the presence of a variety of creators involved in knowledge-intensive activities. Theoretical and practical implications of the results are discussed.

An Evolutionary Perspective on Orgasm
Gallup, G. G., Jr., Towne, J. P., & Stolz, J. A. (2017). An Evolutionary Perspective on Orgasm. Evolutionary Behavioral Sciences, http://dx.doi.org/10.1037/ebs0000104
Abstract: The capacity to experience an orgasm evolved to promote high-frequency sex in species with low reproductive rates. Growing evidence shows that orgasms also have a variety of other reproductive consequences. Based on a distinction between orgasm frequency and orgasm intensity, there is emerging evidence in humans that orgasms function to promote and fine tune what are often very different, sex-specific reproductive outcomes. We provide an overview of the effect of hormonal contraceptives on orgasm, mate choice, and sexual satisfaction. The effects of sex during pregnancy, along with orgasm induced vocalizations, facial expressions during orgasm, and the putative effects of semen exposure on orgasm and sexual functioning in females are also discussed. Recent research suggests that female orgasms evolved to promote good mate choices, and we propose that instances of orgasmic dysfunction in many women may be a byproduct of an inability to find and/or retain high-quality male partners.
---
Factor into this matrix evidence showing that women who engage in extrapair copulations are more likely to be in the fertile phase of their cycle, less likely to use contraception, and more likely to experience orgasm (Baker & Bellis, 1993), and it becomes apparent that females may have been shaped by their evolutionary history to use extrapair copulations to bare children sired by genetically superior males and/or to increase the range of genetic variation among their existing children (Gallup & Burch, 2006). By the time a woman has had three children sired by the same man, she will have sampled roughly 87.5% of his genes, and therefore, any additional children sired by the same man will be increasingly redundant genetic samples (Gallup & Ampel, 2017). By targeting high-quality males for extrapair copulations women, can have children sired by genetically superior males and as an added bonus, children sired by different males represents a hedge against an uncertain future. Consistent with this analysis women are not only more likely to experience orgasm, they also report more intense orgasms as a result of extrapair copulations (Gallup, Burch, & Mitchell, 2006). Therefore, if you are a woman whether you experience an orgasm and who you experience an orgasm with may make an important difference. Moreover, it seems reasonable to suppose that variation in orgasm intensity ought to be proportional to the magnitude of the vaginal and intrauterine contractions that occur during orgasm, which puts a reproductive premium on orgasm intensity. Suffice it to say that for all of these reasons, Lloyd’s (2005) claimed that orgasm in women was not subject to natural selection is untenable.
In contrast to females, it has been suggested that variation in ratings of orgasm intensity among males is an index or proxy for sperm recruitment (Gallup et al., 2012). Gallup et al. predicted that the ejaculate which accompanies more intense orgasms will contain more sperm and higher concentrations of other seminal chemicals tailored to make conception more likely. For example, recent research by Pham et al. (2016) shows that estimates of ejaculate volume as a measure of ejaculate quality, correlate with the duration of cunnilingus as a prelude to sexual intercourse. Because of a history of competition for paternity, coupled with the high costs of being cuckolded, we predict that indications of partner infidelity ought to also be conducive to the occurrence of more intense orgasms in men. In other words, while more intense female orgasms may function as a mate choice mechanism, more intense orgasms in men may be a reflection of sperm recruitment mechanisms that function to compete with the possibility of rival male semen in their partner’s reproductive tract. A seemingly counterintuitive but nonetheless testable prediction that follows from this analysis would be that males who fantasize about partner infidelity during sex or masturbation would be expected to experience more intense orgasms. The growing prevalence of websites on the Internet that cater to such male fantasies provides suggestive evidence for such an effect. Research by Joyal, Cossette, and Lapierre (2015), showing that a significant proportion of men fantasize about having sex with couples that they and their partner know as well as couples they do not, is also consistent with this hypothesis.
A corollary prediction would be that variation in the reproductive value of different female partners ought to be proportional to corresponding variation in male orgasm intensity. This could be tested by partitioning variation in the appearance of females depicted in pornographic videos to see if the composition of semen samples taken from males who masturbate while watching such videos varies as a function of how they rate their orgasms and as a function of objective variation in different fitness indicators among female pornography stars such as waist to hip ratios, facial attractiveness, breast size, and so forth. Variations in most physical dimensions of interpersonal attraction and sex appeal are well-documented proxies for underlying differences in health and fertility (Gallup & Frederick, 2010).
Recently, Joseph, Sharma, Agarwal, and Sirot (2015) found that ejaculate quality (as indexed by parameters such as ejaculate volume and number of motile sperm) goes up when men are exposed to novel/unfamiliar women, and men ejaculate faster when shown a new woman following a series of repeated exposures to the same woman. Thus, not surprisingly, the Coolidge effect (for a review, see Dewsbury, 1981) appears to be accompanied by testicular adjustments that make for a higher quality ejaculate, and we predict that under such conditions, males will report corresponding increases in orgasm intensity as well.
It is interesting that there may even be an assortative mating/social comparison component to such testicular adjustments. Leivers, Rhodes, and Simmons (2014a) found an interaction between male mate value and female attractiveness for measures of ejaculate quality. Men with high mate value (based on attractiveness, dominance and self-perceived mate value) only produced high-quality ejaculates when given the opportunity to view images of attractive females. Just the opposite was true for men of low mate value, who produced lower quality ejaculates when viewing attractive females. Thus, there appears to be a context dependent effect on ejaculate quality that interacts with the mate value of the male and the attractiveness of the female. High-value males only allocate high-quality ejaculates to attractive females. Also implicating the existence of specialized ejaculate allocation mechanisms based on tradeoff effects, Leivers, Rhodes, and Simmons (2014b) found that men who engage in fewer mate guarding behaviors produce higher quality ejaculates.
In the context of the social psychological properties of orgasm and intersexual reproductive competition, evidence shows that some women fake orgasms in an effort to promote partner retention (Kaighobadi, Shackelford, & Weekes-Shackelford, 2012). Consistent with these results implicating attempts by women to feign orgasms to manipulate their mates, Brewer and Hendrie (2011) found that rather than being triggered by orgasm, copulatory vocalizations by some women were more likely to occur during male ejaculation. Indeed, Ellsworth and Bailey (2013) found that faked orgasms were correlated with the likelihood that women had engaged in sexual infidelity. Ellsworth and Bailey also found that males were more sexually satisfied with females who experienced more intense and frequent orgasms, and therefore, they speculate that variation in female orgasms may convey information about the probability of paternity.

Do Orgasms Give Women Feedback About Mate Choice? Gordon G. Gallup et al. Evolutionary Psychology, 2014. 12(5): 957-977. https://www.researchgate.net/publication/308086891
Abstract: The current study represents a preliminary investigation of the extent to which
female orgasm functions to promote good mate choices. Based on a survey of heterosexual female college students in committed relationships, how often women experienced orgasm as a result of sexual intercourse was related to their partner’s family income, his selfconfidence, and how attractive he was. Orgasm intensity was also related to how attracted they were to their partners, how many times they had sex per week, and ratings of sexual satisfaction. Those with partners who their friends rated as more attractive also tended to have more intense orgasms. Orgasm frequency was highly correlated (r = .82) with orgasm intensity, and orgasm intensity was a marginally better predictor of sexual satisfaction than orgasm frequency. Sexual satisfaction was related to how physically attracted women were to their partner and the breadth of his shoulders. Women who began having sexual intercourse at earlier ages had more sex partners, experienced more orgasms, and were more sexually satisfied with their partners. We also identified an ensemble of partner psychological traits (motivation, intelligence, focus, and determination) that predicted how often women initiated sexual intercourse. Their partner’s sense of humor not only predicted his self-confidence and family income, but it also predicted women’s propensity to initiate sex, how often they had sex, and it enhanced their orgasm frequency in comparison with other partners.

Bystanders intervene to impede grooming in Western chimpanzees and sooty mangabeys
Bystanders intervene to impede grooming in Western chimpanzees and sooty mangabeys. Alexander Mielke, Liran Samuni, Anna Preis, Jan F. Gogarten, Catherine Crockford, Roman M. Wittig. Royal Society Open Science, DOI: 10.1098/rsos.171296
Abstract: Grooming interactions benefit groomers, but may have negative consequences for bystanders. Grooming limits bystanders' grooming access and ensuing alliances could threaten the bystander's hierarchy rank or their previous investment in the groomers. To gain a competitive advantage, bystanders could intervene into a grooming bout to increase their own grooming access or to prevent the negative impact of others' grooming. We tested the impact of dominance rank and social relationships on grooming intervention likelihood and outcome in two sympatric primate species, Western chimpanzees (Pan troglodytes verus) and sooty mangabeys (Cercocebus atys atys). In both species, rather than increasing their own access to preferred partners, bystanders intervened mainly when an alliance between groomers could have a negative impact on them: when the lower-ranking groomer was close to the bystander in rank, when either groomer was an affiliation partner whose services they could lose, or the groomers were not yet strongly affiliated with each other. Thus, bystanders in both species appear to monitor grooming interactions and intervene based on their own dominance rank and social relationships, as well as triadic awareness of the relationship between groomers. While the motivation to intervene did not differ between species, mangabeys appeared to be more constrained by dominance rank than chimpanzees.

The Humanizing Voice: Speech Reveals, and Text Conceals, a More Thoughtful Mind in the Midst of Disagreement
The Humanizing Voice: Speech Reveals, and Text Conceals, a More Thoughtful Mind in the Midst of Disagreement. Juliana Schroeder, Michael Kardas, Nicholas Epley. Psychological Science, https://doi.org/10.1177/0956797617713798
Abstract: A person’s speech communicates his or her thoughts and feelings. We predicted that beyond conveying the contents of a person’s mind, a person’s speech also conveys mental capacity, such that hearing a person explain his or her beliefs makes the person seem more mentally capable—and therefore seem to possess more uniquely human mental traits—than reading the same content. We expected this effect to emerge when people are perceived as relatively mindless, such as when they disagree with the evaluator’s own beliefs. Three experiments involving polarizing attitudinal issues and political opinions supported these hypotheses. A fourth experiment identified paralinguistic cues in the human voice that convey basic mental capacities. These results suggest that the medium through which people communicate may systematically influence the impressions they form of each other. The tendency to denigrate the minds of the opposition may be tempered by giving them, quite literally, a voice.

Abstract: Values-pragmatics theory (Hodges & Geyer, 2006) predicts that people will sometimes disagree with others they believe are correct, for reasons similar to those explaining agreement with incorrect answers in an Asch (1956) situation. In 3 experiments, we found evidence that people in a position of ignorance sometimes do not agree with the correct answers of others in positions of knowledge. Experiments 1a and 1b found this speaking-from-ignorance (SFI) effect occurred 27% of the time. Experiment 2 introduced experimental controls and self-report data indicating that the SFI effect (30%) was generated by realizing values (e.g., truth, social solidarity) and pragmatic constraints to act cooperatively, rather than by a wide array of alternatives (e.g., normative pressure, reactance). Experiment 3 experimentally manipulated concern for truthfulness, yielding 49% nonagreeing answers, even though there were monetary incentives to give correct, agreeing answers. The overall pattern suggests that people are not so much conformists or independents as they are cooperative truth tellers under social and moral constraints. Results, while surprising for social influence theories, illustrate the dynamics of divergence and convergence that appear across studies in cultural anthropology and developmental psychology, as well as in social psychology.

Users who feature either cat or dog images in their tweets are more neurotic, less conscientious, and less agreeable
Personality Profiles of Users Sharing Animal-related Content on Social Media. Courtney Hagan, Jordan Carpenter, Lyle Ungar & Daniel Preotiuc-Pietro. Anthrozoös, Volume 30, 2017, Issue 4, Pages 671-680. http://www.tandfonline.com/doi/abs/10.1080/08927936.2017.1370235
ABSTRACT: Animal preferences are thought to be linked with more salient psychological traits of people, and most research examining owner personality as a differentiating factor has obtained mixed results. The rise in usage of social networks offers users a new medium in which they can broadcast their preferences and activities, including about animals. In two studies, the first on Facebook status updates and the second on images shared on Twitter, we revisited the link between Big Five personality traits and animal preference, specifically focusing on cats and dogs. We used automatic content analysis of text and images to unobtrusively measure preference for animals online using large datasets. In study 1, a dataset of Facebook status updates (n = 72,559) were analyzed and it was found that those who mentioned ownership of a cat (by using the phrase “my cat” (n = 5,053)) in their status updates were more open to experience, introverted, neurotic, and less conscientious when compared with the general population. Users mentioning ownership of a dog (by using “my dog” (n = 8,045)) were only less conscientious compared with the rest of the population. In study 2, a dataset of Twitter images was analyzed and revealed that users who featured either cat (n = 1,036) or dog (n = 1,499) images in their tweets were more neurotic, less conscientious, and less agreeable than those who did not. In addition, posting images containing cats was specific to users higher in openness, while posting images featuring dogs was associated with users higher in extraversion. These findings taken together align with some previous findings on the relationship between owner personality and animal preference, additionally highlighting some social media-specific behaviors.

Supernatural Belief Is Not Modulated by Intuitive Thinking Style or Cognitive Inhibition
Supernatural Belief Is Not Modulated by Intuitive Thinking Style or Cognitive Inhibition. Miguel Farias et al. Scientific Reports 7, Article number: 15100 (2017), doi:10.1038/s41598-017-14090-9
Abstract: According to the Intuitive Belief Hypothesis, supernatural belief relies heavily on intuitive thinking—and decreases when analytic thinking is engaged. After pointing out various limitations in prior attempts to support this Intuitive Belief Hypothesis, we test it across three new studies using a variety of paradigms, ranging from a pilgrimage field study to a neurostimulation experiment. In all three studies, we found no relationship between intuitive or analytical thinking and supernatural belief. We conclude that it is premature to explain belief in gods as ‘intuitive’, and that other factors, such as socio-cultural upbringing, are likely to play a greater role in the emergence and maintenance of supernatural belief than cognitive style.

In humans, some sexual traits suggest monogamous mating, while others suggest selection for polygyny
Humans as a model species for sexual selection research. Michael Lawrence Wilson, Carrie M. Miller, Kristin N. Crouse. Proceedings of the Royal Society B, Volume 284, issue 1866. DOI: 10.1098/rspb.2017.1320
Abstract: Ever since Darwin, questions about humans have driven sexual selection research. While studies of other organisms are often justified as useful for improving understanding of humans, humans themselves can be useful models. Although humans present some drawbacks as model organisms (complicated societies, slow reproduction and strong ethical constraints on experimental options), humans nonetheless offer many advantages (being abundant, accessible and having detailed historical records for some populations). As an additional challenge, humans exhibit a rather puzzling combination of traits. Some traits (pair-bonding, biparental care and modest sexual dimorphism in body size) suggest selection for monogamous mating, while other traits (including sexual dimorphism in body composition and appearance) suggest selection for polygyny. Such puzzles have motivated research on other species, resulting in a rich set of comparative data that provides insights into humans and other species. Recent studies of visual trait dimorphism suggest that human appearance reflects adaptation for multi-level societies, rather than high levels of polygyny. In addition to biological traits, human cultural traits have undergone rapid evolution. Changes in subsistence strategies profoundly affect opportunities for sexual selection. The enormous variability of human behaviour and ecology provides abundant opportunities to test key hypotheses, and poses challenging puzzles for future research.

Personality traits AND social relationships are deeply entwined in a bidirectional way

Johansen (Ed.), Your personality makes you ill: Scientific proof or wishful thinking? San Diego: Elsevier, expected Jan 2018. Available from: https://www.researchgate.net/publication/319527661_Personality_and_social_relationships_As_thick_as_thieves
Abstract: This chapter shows that personality traits and social relationships are deeply entwined in a bidirectional way: Individuals select relationships partly based on their personality traits but at the same time develop across the lifespan partly in response to changes in their social environment. Life transitions are an important catalyst of changes in personality-relationship transactions. We argue that personality traits and social relationships are so closely tied that, in our view, the link between personality and health can only be understood against the backdrop of individuals’ relationships.

Deviations from expectations drive tipping behavior more so than wins and losses, and especially close wins
Sports Sentiment and Tipping Behavior. Qi Ge. Journal of Economic Behavior & Organization, https://doi.org/10.1016/j.jebo.2017.10.016
Highlights
• Utilize data on taxi rides in New York City to investigate how emotions due to sporting event outcomes affect passengers’ tipping behavior.
• Formulate and test a reference-dependent preferences framework of tipping behavior.
• Find that deviations from expectations drive tipping behavior more so than wins and losses, with the most salient effects found under unexpected close wins.
• Find no support for loss aversion in the context of tipping behavior.
Abstract: This paper utilizes a high frequency dataset on taxi rides in New York City to investigate how emotions due to sporting event outcomes affect passengers’ tipping behavior. I formulate and empirically test a reference-dependent preferences framework of tipping behavior. The results indicate that the tipping amounts are driven by deviations from expectations much more so than wins and losses, with the most salient effects found under unexpected close wins. However, there is no support for loss aversion. The findings suggest that loss averse behavior may be subdued in the presence of social norms while surprises can result in freedom on the upside of tipping.

Your attention makes me smile: Direct gaze elicits affiliative facial expressions
Your attention makes me smile: Direct gaze elicits affiliative facial expressions. Jari K. Hietanen et al. Biological Psychology, https://doi.org/10.1016/j.biopsycho.2017.11.001
Highlights
• Facial EMG and autonomic responses were measured to another individual’s direct and averted gaze.
• Greater zygomatic responses were elicited by seeing another person with direct than averted gaze.
• The results suggest that another individual’s direct gaze is an affiliative, positive signal.
Abstract: Facial electromyographic responses and skin conductance responses were measured to investigate whether, in a neutral laboratory environment, another individual’s direct gaze elicits a positive or negative affective reaction in the observer. The results showed that greater zygomatic responses associated with positive affect were elicited by seeing another person with direct as compared to averted gaze. The zygomatic responses were greater in response to another person’s direct gaze both when the participant’s own gaze was directed towards the other and when the participant was not looking directly towards the other. Compatible with the zygomatic responses, the corrugator activity (associated with negative affect) was decreased below baseline more in response to another person’s direct than averted gaze. Replicating previous research, the skin conductance responses were greater to another person’s direct than averted gaze. The results provide evidence that, in a neutral context, another individual’s direct gaze is an affiliative, positive signal.

Your need to correct wrong information you believed depends on your cognitive abilities, not your political leaning
‘Fake news’: Incorrect, but hard to correct. The role of cognitive ability on the impact of false information on social impressions. Jonas de Keersmaecker, Arne Roets. Intelligence, https://doi.org/10.1016/j.intell.2017.10.005
Highlights
• Interplay between cognitive ability and false information on attitudes was examined.
• When people learn their attitudes are based on false information, they adjust them.
• People low (vs high) in cognitive ability adjust attitudes to lesser extent.
• Adjusted attitudes remained biased for people low in cognitive ability.
Abstract: The present experiment (N = 390) examined how people adjust their judgment after they learn that crucial information on which their initial evaluation was based is incorrect. In line with our expectations, the results showed that people generally do adjust their attitudes, but the degree to which they correct their assessment depends on their cognitive ability. In particular, individuals with lower levels of cognitive ability adjusted their attitudes to a lesser extent than individuals with higher levels of cognitive ability. Moreover, for those with lower levels of cognitive ability, even after the explicit disconfirmation of the false information, adjusted attitudes remained biased and significantly different from the attitudes of the control group who was never exposed to the incorrect information. In contrast, the adjusted attitudes of those with higher levels of cognitive ability were similar to those of the control group. Controlling for need for closure and right-wing authoritarianism did not influence the relationship between cognitive ability and attitude adjustment. The present results indicate that, even in optimal circumstances, the initial influence of incorrect information cannot simply be undone by pointing out that this information was incorrect, especially in people with relatively lower cognitive ability.

Experiencing disagreement is linked to experiencing more other-condemning emotions, less well-being, and less humanity-esteem. Ideology doesn't moderate these.
Brandt, Mark J, Jarret Crawford, and Daryl Van Tongeren. 2017. “Worldview Conflict in Daily Life”. PsyArXiv. September 29. doi:10.1177/1948550617733517
Abstract: Building on laboratory and survey-based research probing the psychology of ideology and the experience of worldview-conflict, we examined the association between worldview-conflict and emotional reactions, psychological well-being, humanity-esteem, and political ideology in everyday life using experience sampling. In three combined samples (Total N= 328), experiencing disagreement compared to agreement was associated with experiencing more other-condemning emotions, less well-being, and less humanity-esteem. There were no clear associations between experiencing disagreement and experiencing self-conscious emotions, positive emotions, and mental stress. None of the relationships were moderated by political ideology. These results both replicate and challenge findings from laboratory and survey-based research, and we discuss possible reasons for the discrepancies. Experience sampling methods can help researchers get a glimpse into everyday worldview-conflict.
