Momentary increases in deprivation, hunger, and boredom increased likelihood of diatary lapse types; eating at an unintended time was the only lapse type that predicted worse weight loss outcomes

Using ecological momentary assessment to better understand dietary lapse types. Stephanie P.Goldstein et al. Appetite, https://doi.org/10.1016/j.appet.2018.07.003

Abstract: Frequency of lapsing from a diet predicts weight loss failure, however previous studies have only utilized one definition of dietary lapse. No study has examined different types of lapse behaviors among individuals with overweight/obesity. The current study uses ecological momentary assessment (EMA) to examine predictors of three lapse types—eating a larger portion than intended, eating an unintended type of food, and eating at an unplanned time—in adults (N = 189; MBMI = 36.93 ± 5.83 kg/m2; 82.0% female; Mage = 51.81 ± 9.76 years) enrolled in a 12-month randomized controlled trial of two behavioral weight loss treatments. Participants completed 14 days of EMA at the start of treatment during which they indicated types of lapses that occurred with time and location of the lapse. Participants also responded to questions assessing current physical (e.g., hunger, tiredness), environmental (e.g., presence of “delicious” foods), and affective (e.g., loneliness, sadness) states at each prompt. Weight change was assessed at post-treatment. Separate generalized estimating equations were used to examine whether states prospectively predicted lapse occurrence at the next survey. Results indicated that lapse types differed significantly across time and location. Momentary increases in deprivation, hunger, and boredom increased likelihood of different lapse types. Lastly, we examined the prospective association between lapse type and weight loss. Eating at an unintended time was the only lapse type that predicted worse weight loss outcomes. Results support the theory that distinct lapse types exist, and that lapse types can be predicted by both momentary conditions and individual tendencies toward certain physical and affective states. However, not all lapse types may impact weight outcomes. Future research on behaviors that constitute dietary lapse is warranted and could inform personalized weight loss treatments.

Individuals higher in gender self-confidence were less likely to choose to be reincarnated as the other sex; those older, more religious, more negative towards gays, & high higher gender self-confidence were less likely to choose to experience being the other sex even for a week

Factors Influencing Cisgender Individuals’ Interest in Experiencing Being the Other Sex. E. Sandra Byers, Kaitlyn M. Goldsmith, Amanda Miller. Gender Issues, https://link.springer.com/article/10.1007/s12147-018-9219-z

Abstract: In this study we asked people about their hypothetical interest in experiencing being the other sex as a possible means to capture their implicit gender-related attitudes and assumptions. As such, we sought to identify the extent to which gender self-confidence, openness to experience, and conservative attitudes are associated with hypothetically having this experience permanently (i.e., through reincarnation) and temporarily (i.e., for 1 week). Participants were 208 cisgender individuals (107 men, 101 women) who completed an on-line survey. A logistic regression analysis demonstrated that individuals higher in gender self-confidence were less likely to choose to be reincarnated as the other sex. A multiple regression analysis demonstrated that individuals who were older, more religious, had more negative attitudes towards gay men and lesbians, and high higher gender self-confidence were less likely to choose to experience being the other sex for a week. Gender identity, age, religiosity, and openness were not related to interest in being the other sex permanently or temporarily. These results demonstrate the potential utility of this approach for assessing implicit gender-related attitudes. They are discussed in terms of the multiple factors associated with these attitudes.

98% of web users missed absurd clauses in terms of service about data sharing with the NSA & employers, & about providing a first-born child as payment for access

The biggest lie on the Internet: ignoring the privacy policies and terms of service policies of social networking services. Jonathan A. Obar & Anne Oeldorf-Hirsch. Information, Communication & Society, https://doi.org/10.1080/1369118X.2018.1486870

ABSTRACT: This paper addresses ‘the biggest lie on the internet’ with an empirical investigation of privacy policy (PP) and terms of service (TOS) policy reading behavior. An experimental survey (N = 543) assessed the extent to which individuals ignored PP and TOS when joining a fictitious social networking service (SNS), NameDrop. Results reveal 74% skipped PP, selecting the ‘quick join’ clickwrap. Average adult reading speed (250–280 words per minute), suggests PP should have taken 29–32 minutes and TOS 15–17 minutes to read. For those that didn’t select the clickwrap, average PP reading time was 73 seconds. All participants were presented the TOS and had an average reading time of 51 seconds. Most participants agreed to the policies, 97% to PP and 93% to TOS, with decliners reading PP 30 seconds longer and TOS 90 seconds longer. A regression analysis identifies information overload as a significant negative predictor of reading TOS upon sign up, when TOS changes, and when PP changes. Qualitative findings suggest that participants view policies as nuisance, ignoring them to pursue the ends of digital production, without being inhibited by the means. Implications are revealed as 98% missed NameDrop TOS ‘gotcha clauses’ about data sharing with the NSA and employers, and about providing a first-born child as payment for SNS access.

Prolonged sitting is linked to increased disease & premature mortality risk; but standing at work as a way of reducing sitting generated marked psychological discomfort due to concern at being seen to be violating a strong perceived sitting norm

“Could you sit down please?” A qualitative analysis of employees’ experiences of standing in normally-seated workplace meetings. Louise Mansfield et al. PLOS One, https://doi.org/10.1371/journal.pone.0198483

Abstract: Office workers spend most of their working day sitting, and prolonged sitting has been associated with increased risk of poor health. Standing in meetings has been proposed as a strategy by which to reduce workplace sitting but little is known about the standing experience. This study documented workers’ experiences of standing in normally seated meetings. Twenty-five participants (18+ years), recruited from three UK universities, volunteered to stand in 3 separate, seated meetings that they were already scheduled to attend. They were instructed to stand when and for however long they deemed appropriate, and gave semi-structured interviews after each meeting. Verbatim transcripts were analysed using Framework Analysis. Four themes, central to the experience of standing in meetings, were extracted: physical challenges to standing; implications of standing for meeting engagement; standing as norm violation; and standing as appropriation of power. Participants typically experienced some physical discomfort from prolonged standing, apparently due to choosing to stand for as long as possible, and noted practical difficulties of fully engaging in meetings while standing. Many participants experienced marked psychological discomfort due to concern at being seen to be violating a strong perceived sitting norm. While standing when leading the meeting was felt to confer a sense of power and control, when not leading the meeting participants felt uncomfortable at being misperceived to be challenging the authority of other attendees. These findings reveal important barriers to standing in normally-seated meetings, and suggest strategies for acclimatising to standing during meetings. Physical discomfort might be offset by building standing time slowly and incorporating more sit-stand transitions. Psychological discomfort may be lessened by notifying other attendees about intentions to stand. Organisational buy-in to promotional strategies for standing may be required to dispel perceptions of sitting norms, and to progress a wider workplace health and wellbeing agenda.

The experience of providing Likes to others on social media related to activation in brain circuity implicated in reward, including the striatum and ventral tegmental area, regions also implicated in the experience of receiving Likes from other

What the Brain “Likes:” Neural Correlates of Providing Feedback on Social Media. Lauren E Sherman, Leanna M Hernandez, Patricia M Greenfield, Mirella Dapretto. Social Cognitive and Affective Neuroscience, nsy051, https://doi.org/10.1093/scan/nsy051

Abstract: Evidence increasingly suggests that neural structures that respond to primary and secondary rewards are also implicated in the processing of social rewards. The “Like” – a popular feature on social media – shares features with both monetary and social rewards as a means of feedback that shapes reinforcement learning. Despite the ubiquity of the Like, little is known about the neural correlates of providing this feedback to others. In the present study, we mapped the neural correlates of providing Likes to others on social media. Fifty-eight adolescents and young adults completed a task in the MRI scanner designed to mimic the social photo-sharing app Instagram. We examined neural responses when participants provided positive feedback to others. The experience of providing Likes to others on social media related to activation in brain circuity implicated in reward, including the striatum and ventral tegmental area, regions also implicated in the experience of receiving Likes from others. Providing Likes was also associated with activation in brain regions involved in salience processing and executive function. We discuss the implications of these findings for our understanding of the neural processing of social rewards, as well as the neural processes underlying social media use.

A man becomes a beast in 3 weeks, given heavy labor, cold, hunger, and beatings; the main means for depraving the soul is the cold; friendship, comradeship, would never arise in really difficult, life-threatening conditions


Forty-Five Things I Learned in the Gulag. Varlam Shalamov. June 12, 2018. https://www.theparisreview.org/blog/2018/06/12/forty-five-things-i-learned-in-the-gulag/

Excerpts:

For fifteen years the writer Varlam Shalamov was imprisoned in the Gulag for participating in “counter-revolutionary Trotskyist activities.” He endured six of those years enslaved in the gold mines of Kolyma, one of the coldest and most hostile places on earth. While he was awaiting sentencing, one of his short stories was published in a journal called Literary Contemporary. He was released in 1951, and from 1954 to 1973 he worked on Kolyma Stories, a masterpiece of Soviet dissident writing that has been newly translated into English and published by New York Review Books Classics this week. Shalamov claimed not to have learned anything in Kolyma, except how to wheel a loaded barrow. But one of his fragmentary writings, dated 1961, tells us more.

1. The extreme fragility of human culture, civilization. A man becomes a beast in three weeks, given heavy labor, cold, hunger, and beatings.

2. The main means for depraving the soul is the cold. Presumably in Central Asian camps people held out longer, for it was warmer there.

3. I realized that friendship, comradeship, would never arise in really difficult, life-threatening conditions. Friendship arises in difficult but bearable conditions (in the hospital, but not at the pit face).

4. I realized that the feeling a man preserves longest is anger. There is only enough flesh on a hungry man for anger: everything else leaves him indifferent.

5. I realized that Stalin’s “victories” were due to his killing the innocent—an organization a tenth the size would have swept Stalin away in two days.

6. I realized that humans were human because they were physically stronger and clung to life more than any other animal: no horse can survive work in the Far North.

7. I saw that the only group of people able to preserve a minimum of humanity in conditions of starvation and abuse were the religious believers, the sectarians (almost all of them), and most priests.

8. Party workers and the military are the first to fall apart and do so most easily.

9. I saw what a weighty argument for the intellectual is the most ordinary slap in the face.

10. Ordinary people distinguish their bosses by how hard their bosses hit them, how enthusiastically their bosses beat them.

11. Beatings are almost totally effective as an argument (method number three).

[...]

19. Both my physical and my spiritual strength turned out to be stronger than I thought in this great test, and I am proud that I never sold anyone, never sent anyone to their death or to another sentence, and never denounced anyone.

[...]

28. The passion for power, to be able to kill at will, is great—from top bosses to the rank-and-file guards (Seroshapka and similar men).

29. Russians’ uncontrollable urge to denounce and complain.

[...]

While incarcerated offenders showed a high rate of cheating, levels of psychopathic traits did not influence the frequency of dishonesty; higher psychopathy scores predicted decreased activity in the ACC during dishonest decision-making

Reduced engagement of the anterior cingulate cortex in the dishonest decision-making of incarcerated psychopaths. Nobuhito Abe, Joshua D Greene, Kent A Kiehl. Social Cognitive and Affective Neuroscience, nsy050, https://doi.org/10.1093/scan/nsy050

Abstract: A large body of research indicates that psychopathic individuals lie chronically and show little remorse or anxiety. Yet, little is known about the neurobiological substrates of dishonesty in psychopathy. In a sample of incarcerated individuals (N = 67), we tested the hypothesis that psychopathic individuals show reduced activity in the anterior cingulate cortex (ACC) when confronted with an opportunity for dishonest gain, reflecting dishonest behavior that is relatively unhindered by response conflict. During functional magnetic resonance imaging (fMRI), incarcerated offenders with different levels of psychopathy performed an incentivized prediction task wherein they were given real and repeated opportunities for dishonest gain. We found that while incarcerated offenders showed a high rate of cheating, levels of psychopathic traits did not influence the frequency of dishonesty. Higher psychopathy scores predicted decreased activity in the ACC during dishonest decision-making. Further analysis revealed that the ACC was functionally connected to the dorsolateral prefrontal cortex (DLPFC), and that ACC activity mediated the relationship between psychopathic traits and reduced reaction times (RTs) for dishonest behavior. These findings suggest that psychopathic individuals behave dishonestly with relatively low levels of response conflict and that the ACC may play a critical role in this pattern of behavior.

Many consumers claim to have a positive attitude towards ethical products, but reported purchases show that this behavior is not consistent; taste and perceived health benefits, could be seen to generate higher consumers’ commitment

Coffee consumption and purchasing behavior review: Insights for further research. Antonella Samoggia, Bettina Riedel. Appetite, https://doi.org/10.1016/j.appet.2018.07.002

Abstract: This paper presents a systematic literature review of consumer research towards coffee with the objective to identify and categorize motives, preferences and attributes of coffee consumption and purchasing behavior. Research papers were analyzed in terms of main characteristics and components (study type, research methodology, sampling, and product type). The review gives a systematic overview of the heterogeneous group of concepts and approaches that have been used so far to examine consumer behavior towards coffee. Results provide a model of key determinants for coffee consumption that can be grouped into the categories, (1) personal preferences, (2) economic attributes, (3) product attributes, (4) context of consumption, and (5) socio-demographics. The findings also show that there is a strong focus on coffee sustainability.

Eveningness is related to increased sociosexuality; having nocturnal short-term sexual strategies is an adaptive niche-exploiting behavior for both men and women that is governed by natural selection

Evening chronotype is associated with a more unrestricted sociosexuality in men and women. Robert L.Matchock. Personality and Individual Differences, Volume 135, 1 December 2018, Pages 56-59. https://doi.org/10.1016/j.paid.2018.06.054

Abstract: Chronotype and sociosexuality have been reported to be associated with each other and to also be sexually dimorphic. Specifically, research has suggested a link between evening chronotypes and increased sociosexuality, but the research is sparse, including the extent to which gender may interact with chronotype and sociosexuality. To that end, the present study administered the Horne and Ostberg morningness/eveningness questionnaire (MEQ) and the revised Sociosexual Orientation Inventory (SOI-R), which consists of behavior, attitude, and desire subscales, to 554 participants (61.7% female). Results indicated that men had a more unrestricted sociosexuality than women, except for the behavioral subscale. Eveningness was related to increased sociosexuality for both men (except the behavioral subscale) and women (for all subscales). It is suggested that adopting phase-delayed nocturnal short-term sexual strategies is an adaptive niche-exploiting behavior for both men and women that is governed by natural selection.

Justice was swift with ISIS... Before, “You have to have wasta —a connection to someone— for the police to take your case under consideration"

The Case of the Purloined Poultry: How ISIS Prosecuted Petty Crime. Rukmini Callimachi. The New York Times, Jul 01 2018, https://www.nytimes.com/2018/07/01/world/middleeast/islamic-state-iraq.html

Excerpts:

TEL KAIF, Iraq — The crime scene was Stall No. 200 in a market eight miles north of Mosul, Iraq.

It was there that Zaid Imad Khalaf, 24, made a living selling chickens, scraping by next to a grocer who sold onions by the kilogram and a trader who sold flour by the scoop.

And it was there that an Islamic State soldier, one of the thousands who ruled the plains of northern Iraq, walked by and pointed to Mr. Imad’s plumpest chicken. “That one,” he said.

Mr. Imad butchered the bird, plucked it, weighed it and then asked for the 8,000 dinars he was owed, around $7. That’s when the problems started. “When he went to pull the money from his pocket he said that he only had 4,000 dinars and said he would pay me the rest tomorrow,” Mr. Imad recalled.

Normally, the story should have ended there, with a poor man being stiffed by a more powerful one.

And yet a week after the incident in 2016, Mr. Imad did something that might seem foolhardy when the rulers of your city have a reputation for unbridled brutality: He lodged a complaint for the missing $3.50 with the town’s Islamic Police station. The next day, the Islamic State fighter hurried in to pay the amount he owed.

It was a quick, neat and efficient resolution to the pettiest of problems, one which probably would have gone unheeded before the arrival of the militants.

In a terrorist version of the “broken window” school of policing, the Islamic State aggressively prosecuted minor crimes in the communities it took over, winning points with residents who were used to having to pay bribes to secure police help.

[...]
The documents show that the Islamic State, also known as ISIS, was willing — even eager — to get involved in the messy details of people’s day-to-day lives, and conversely that hundreds of people trusted them to fairly resolve their issues, no matter how trivial.

With the Islamic State’s territory reduced to a fraction of what it once was, the world’s attention has moved on. Yet the records shed light on how the group managed to hold onto so much land in the first place. And with ISIS still in control of approximately 1,000 square miles in Iraq and Syria, they may also offer lessons about the battles ahead.

The records are contained in hundreds of files recovered from a cluster of buildings in the northern Iraqi town of Tel Kaif, which had housed the group’s Shorta Islamiya — its Islamic police force. Most of the papers were discovered by Iraqi security forces who liberated the area in early 2017. They in turn handed them over to The New York Times, so that their contents could be shared with the world.

Grocers, convenience store owners and traders who sold their goods on credit turned to the Islamic State government when customers failed to pay. They sought reimbursement for a cow, a bird, meat, wheat, vegetables, an oil change and a heater. One filed a report for the 150 meters of electrical wire he hadn’t been compensated for.

Farmers asked for investigations into the crops damaged by livestock. One sought compensation for the watermelons trampled by an errant sheep. Another said his newly planted field had been kicked up by a total of 21 cows. Yet another reported a shepherd who, he said, allowed his flock to graze on his land seven different times. “Each time, I forgive him and he says he won’t do it again, and then he does,” he lamented in the report.

[...]
One father came to complain that a neighbor’s child had kicked his son. (He underlined that the child doing the kicking was bigger than the child being kicked.) Another accused an acquaintance of calling him a “pimp.” Yet another came to file a complaint because he had been called a “shoe.”

Justice was swift and efficient, mostly because no one wanted to risk punishment at the hands of the militants. Yet the fact that hundreds of civilians filed complaints, including against ISIS fighters who had wronged them, suggests that at least some Iraqis believed the terrorist group would do right by them.

Even residents who suffered abuses at the hands of the militants gave them points for their policing, saying that for nonreligious disputes, they were not only fair but also willing to wade into problems that might have been brushed off by most authorities.

Would the Iraqi government have pursued the case of a stolen chicken?

“They wouldn’t have even heard this complaint because it was only for 4,000,” or $3.50, said Mr. Imad’s younger brother, Alosh Imad. “You have to have wasta — a connection to someone,” for the police to take your case under consideration, he explained. “As far as justice was concerned,” he said, “ISIS was better than the government.”

ISIS Repo

Frustrated at being repeatedly brushed off by the fighter, who surely by now had eaten his plumpest bird, Mr. Imad, the chicken seller, padlocked his stall, changed into fresh clothes and headed to the Islamic State police station on Al Bareed Street.

The procedure for filing a complaint involved several steps, and each step involved its own paperwork, the voluminous remnants of which were found at the old station.

The police station was housed in a square room, 20 feet by 20 feet.

The police chief faced Mr. Imad across a large desk. Under the circling of a Chinese-made plastic fan that sliced the thick air, he heard Mr. Imad’s complaint. Then he pulled out a form bearing the terrorist group’s name and, in the field labeled “Case Number,” jotted down: 329.

Then, in blue ink, he filled in the date — Jan. 22, 2016, Sunday, 10 a.m. — before writing down the details of the claim in neat script: “The complainant (Zaid Imad Khalaf) complains that the respondent (Bariq) owes him (4,000 Iraqi dinars) after selling him a chicken.”

Then he pulled out another form, this one a summons. It ordered the ISIS fighter to report to the precinct. “Warning: In the event you do not show up, necessary steps will be taken to punish you,” it said. The police chief then dispatched one of his agents on a scooter, Mr. Imad said, to deliver the summons.

The fighter showed up the next day and immediately paid up, according to a receipt (below).

“In the name of Allah, the Most Merciful, the Most Gracious,” the statement begins. The police officer then filled in the blanks on the form: “An amount (4,000 IQD) was received from (Bariq Sibhan Younis) to be paid to (Zaid Imad Khalaf),” it said. “Remaining amount is zero.”

Both parties signed the form and put their fingerprints on it, dipping their index fingers into bright purple ink, a gesture that aped one of the bureaucratic procedures of the Iraqi government.

To ascertain the authenticity of the documents, The Times showed a cross section of them to six independent analysts who study the Islamic State, including Mara Revkin of Yale University; Aymenn Jawad al-Tamimi of the Middle East Forum; and a team from West Point’s Combating Terrorism Center.

One Tel Kaif resident, Abdulwahid Abdalla, described being on the receiving end of a complaint handled by the militants.

Mr. Abdalla said he had owed his cousin about $145 for the transportation services the cousin provided to help him move some heavy materials. He had managed to pay off half but then stopped making payments because he ran out of money, he said. To his surprise, his cousin lodged a complaint against him.

The Islamic State gave him a deadline. They didn’t care if he didn’t have the money, he said, and instructed him to sell something to come up with it. So Mr. Abdalla, a carpenter, sold some beams he had been saving for a construction job at a loss.

[...]
When the dispute involved one party insulting or harming another, the Islamic State played a role not unlike that of a school principal asking an unruly pupil to apologize.
Case No. 393, for example, involved three shepherds who beat a farmer after he asked them to stop their sheep from trampling his crops. The three signed a statement saying: “I will not attack my Muslim brother Ahmed Mohammed Qadir and I will not swear at him. I will not let my sheep enter lands belonging to Muslims.”

And to make sure that the resolution had teeth, there was also an implicit threat: “In the event I do not keep my promise,” the form reads, “I expect to face any and all legal sanctions and punishments” — which meant only one thing in ISIS-controlled Iraq.

One of the Islamic State’s first priorities when capturing a new area was to win the trust and cooperation of the civilians, whose labor and good will were essential to their state, said Ms. Revkin, the Yale researcher. Among the ways it did this was by providing swift justice, which is one of the most basic functions of any state — and one that was sorely lacking under Iraq’s government.

“ISIS seemed to recognize early on that it could exploit local demands for dignity by listening to people’s complaints and problems and offering some fast solutions,” said Ms. Revkin, who has interviewed more than 200 people who lived in ISIS-controlled areas.

Now in prison, the “emir” of the police station in the village of Sahaji, which had jurisdiction over an 11-mile stretch northwest of Mosul, confirmed that the militants’ goal was to try to win over the population. In a jailhouse interview in northern Iraq, where he spoke with his hands in handcuffs while a guard looked on, he recalled how he had aggressively investigated the case of a shopkeeper who had been owed the equivalent of $4.25.

“If we succeeded in delivering justice, we knew we would win the hearts of the people,” he explained.

As word spread, residents began showing up with complaints about unpaid loans and services dating to well before ISIS came to power. Among them was a complaint for an unpaid bill of $119 from 2010 — or four years before ISIS planted its flag in Tel Kaif. “He has been asking for his money during that period, but the respondent was stalling and delaying until now,” the filing says.

There was also a three-year-old debt of $340 for electricity, a claim for $298 for a three-year-old window installation, a three-year-old unpaid meat bill of $170 and two-year-old claims for $2,115 for vegetables.

[...]
Mr. Salim, a stocky, rosy-faced 26-year-old, said he filed three complaints in the time ISIS ruled the town, one of which was recovered in the files left behind in the police station. Before the militants took over, he recalled, he struggled for over a year to get the $136 owed him by a butcher who frequented his convenience store. “It was as if I was begging him,” he said.
As soon as the Islamic State got involved, the problem disappeared. The man showed up four days later to pay back what was owed.

“It was efficient, because people were afraid of them,” Mr. Salim said. “If you hear you’ve been summoned to the ISIS police station, you’ll do everything to avoid that.”

Prosecuting Their Own

“This case was transferred to the court,” the police officer scribbled in the margin of Case No. 407, a complaint lodged by a woman who said her husband had beaten her in public.

While a majority of the cases were settled inside the police station, the records show that those the group deemed to be the most severe were sent to an Islamic tribunal.

The 87 carbon-copied, prison transfer records found in the police station are an archive of religious zeal. Citizens were thrown in jail for shaving their beards and for more obscure transgressions, like eyebrow plucking.

Men were locked up for sitting too close to a woman, for being found alone with a woman, for wearing tight clothes and even for disobeying their parents. Several were charged with mocking or slandering the Islamic State.

65% of Americans believe they are above average in intelligence: Results of two nationally representative surveys

65% of Americans believe they are above average in intelligence: Results of two nationally representative surveys. Patrick R. Heck, Daniel J. Simons, Christopher F. Chabris. PLOS One, https://doi.org/10.1371/journal.pone.0200103

Abstract: Psychologists often note that most people think they are above average in intelligence. We sought robust, contemporary evidence for this “smarter than average” effect by asking Americans in two independent samples (total N = 2,821) whether they agreed with the statement, “I am more intelligent than the average person.” After weighting each sample to match the demographics of U.S. census data, we found that 65% of Americans believe they are smarter than average, with men more likely to agree than women. However, overconfident beliefs about one’s intelligence are not always unrealistic: more educated people were more likely to think their intelligence is above average. We suggest that a tendency to overrate one’s cognitive abilities may be a stable feature of human psychology.

Rattner in TNYT: The Myth of Corporate America’s Short-Term Thinking

The Myth of Corporate America’s Short-Term Thinking. Steven Rattner. The New York Times Jul 02 2018, https://www.nytimes.com/2018/07/02/opinion/corporate-stock-buyback-short-term-profit.html

American companies, according to their critics, are so focused on making quick profits that they have abdicated building for the long term. That idea has captivated policymakers, commentators and even some leading business executives.

The complaint has reached a fevered pitch amid news that companies are diverting much of their proceeds from the recent tax cut into buying back record amounts of their own shares.

But there is little evidence to back up the idea that American businesses are overly focused on short-term boosts to profits and stock prices.

The easiest path for companies to goose earnings would be to cut back on investment. However, business investment has remained between 11 percent and 15 percent of gross domestic product since 1970. Last year, corporate investment, which includes structures, equipment and the like, totaled 12.6 percent (https://www.bea.gov/iTable/iTable.cfm?reqid=19&step=3&isuri=1&1910=x&0=-99&1921=survey&1903=14&1904=1970&1905=2018&1906=a&1911=0#reqid=19&step=3&isuri=1&1910=x&0=-99&1921=survey&1903=14&1904=1970&1905=2018&1906=a&1911=0) of G.D.P.

Included in those investments is corporate spending on research and development — an undertaking with a long payback — which has reached its highest (http://www.bea.gov/iTable/iTableHtml.cfm?reqid=19&step=3&isuri=1&1910=X&0=-99&1921=survey&1903=14&1904=1970&1905=2018&1906=A&1911=0) ever percentage of G.D.P. and has become a more important part of overall investment.

I have spent three decades analyzing, advising and investing in companies, and I believe American businesses are as willing to fund worthy projects as they have ever been. Investors are fully prepared to back companies focused on the long term. Far from penalizing public companies building for the future, the stock market often rewards them.

Consider America’s five largest public companies by market capitalization: Apple, Amazon, Alphabet (Google), Microsoft and Facebook. All have been investing heavily, and all sport heady valuations.

Amazon, in particular, often appears almost disdainful of profits; last year, it earned just $3 billion on its vast $178 billion of revenues. With a stock market capitalization of $805 billion, that gives it a price to earnings ratio of 268. By comparison, the average S&P 500 company trades at 21 times earnings. On the smaller end, many biotech companies, which often have no revenues, let alone any profits, also trade at handsome (some would say absurd) valuations.

Away from the public markets, a towering wall of venture capital — hardly a short-term investment strategy — stands ready to fund pretty much any vaguely promising new idea.

That brings us back to the stock repurchases. Yes, they often bump up share prices. But they are really a consequence of the vast cash reserves — $2.4 trillion and rising — held by American companies. When top executives don’t see more attractive investment opportunities, at least not in the United States, it can be a prudent use of that cash to buy back shares in their own companies.

As companies return capital to shareholders through buybacks or dividends, the money doesn’t disappear. Its recipients typically reinvest it in other opportunities. That’s not short-term thinking; that’s efficiency.

Advocates of the recent tax legislation say it will provide more incentives for American companies to invest at home. I’d certainly welcome that. But taxes are only part of the equation. Businesses must also see the possibility of attractive returns, which are not always readily available in our relatively slow-growth economy.

That’s why many American companies see greater opportunity to expand abroad. Between 2000 and 2015, American multinationals hired 4.3 million people in the United States but added 6.2 million jobs overseas.

Meanwhile, spending on factories and equipment in the United States has become a less important part of overall business investment, consistent with the decline in manufacturing’s share as companies shift production to lower-cost countries.

Decrying “short-termism” is hardly a new phenomenon. A Harvard Business Review article pronounced that American business is “servicing existing markets rather than creating new ones” and is devoted to “short-term returns and management by the numbers.”

That was in 1980. Nine years later, Akio Morita, the co-founder of Sony, declared that “America looks 10 minutes ahead; Japan looks 10 years.”

Today, American technology firms are, of course, dominant, while Sony is a shadow of its former self.

Across the spectrum, companies in the United States continue to lead the developed world, and profits are at record levels. If American business had been short-term focused since 1980, profits would be falling, not rising, and our companies would be faltering.

Recently, the Business Roundtable — corporate America’s pre-eminent trade organization — called for eliminating quarterly earnings guidance as a means of reducing short-termism. Such recommendations are, at best, a distraction. Only 28 percent of major companies even provide quarterly guidance, and those forecasts help set investors’ expectations and smooth market volatility.

The Business Roundtable should make it a higher priority to call for tighter corporate governance. While the “buddy system” of picking directors has subsided considerably, boards are often still too compliant. Executive compensation (https://www.nytimes.com/2018/05/25/business/top-ceo-pay-packages.html), which has grown exponentially faster than workers’ pay, is out of control and should be more closely tied to long-term performance.

Shareholders should be able to nominate directors more easily. To better represent owners, the roles of chairman and chief executive officer should be split, as they are in many European companies.

But corporate executives recoil from those ideas. They prefer to complain about equity markets that often swiftly punish laggards. Isn’t that what investors are supposed to do?

Again, "no evidence of loss aversion": Cheating, incentives, and money manipulation

Cheating, incentives, and money manipulation. Gary Charness, Celia Blanco-Jimenez, Lara Ezquerra, Ismael Rodriguez-Lara. Experimental Economics, https://link.springer.com/article/10.1007/s10683-018-9584-1

Abstract: We use different incentive schemes to study truth-telling in a die-roll task when people are asked to reveal the number rolled privately. We find no significant evidence of cheating when there are no financial incentives associated with the reports, but do find evidence of such when the reports determine financial gains or losses (in different treatments). We find no evidence of loss aversion in the standard case in which subjects receive their earnings in a sealed envelope at the end of the session. When subjects manipulate the possible earnings, we find evidence of less cheating, particularly in the loss setting; in fact, there is no significant difference in behavior between the non-incentivized case and the loss setting with money manipulation. We interpret our findings in terms of the moral cost of cheating and differences in the perceived trust and beliefs in the gain and the loss frames.

Gender difference in time use decreased 1965-1995, remained constant since; differences in social attitudes by political ideology & income increased over the last four decades; whites and non-whites have converged somewhat on attitudes but have diverged in consumer behavior

Coming Apart? Cultural Distances in the United States over Time. Marianne Bertrand, Emir Kamenica. NBER Working Paper No. 24771, www.nber.org/papers/w24771

Abstract: We analyze temporal trends in cultural distance between groups in the US defined by income, education, gender, race, and political ideology. We measure cultural distance between two groups as the ability to infer an individual's group based on his or her (i) media consumption, (ii) consumer behavior, (iii) time use, or (iv) social attitudes. Gender difference in time use decreased between 1965 and 1995 and has remained constant since. Differences in social attitudes by political ideology and income have increased over the last four decades. Whites and non-whites have converged somewhat on attitudes but have diverged in consumer behavior. For all other demographic divisions and cultural dimensions, cultural distance has been broadly constant over time.

A paper shopping list includes more items than a digital shopping list, & products on the first are less hedonic than those on the second list; also, the use of a digital shopping list leads to more unplanned & hedonic purchases in the store

Write or Type? How a Paper versus a Digital Shopping List Influences the Way Consumers Plan and Shop. Yanliu Huang and Zhen Yang. Journal of the Association for Consumer Research, https://www.journals.uchicago.edu/doi/abs/10.1086/698877

Abstract: This research examines how a traditional handwritten paper shopping list differs from a digital shopping list created on smart devices in influencing consumers’ planning and shopping behavior. We propose that a paper shopping list includes more items than a digital shopping list, and products on a paper shopping list are less hedonic than those on a digital shopping list. Furthermore, the use of a digital shopping list leads to more unplanned and hedonic purchases in the store, while the use of a paper shopping list results in more planned purchases. We also discuss psychological processes underlying these effects. We conduct three studies in which we manipulate shopping list type and track consumers’ actual purchases to provide support for our hypotheses.

Support for redistribution is strongly correlated with the perceived composition of immigrants –their origin & economic contribution– rather than with the perceived share of immigrants per se

Immigration and Redistribution. Alberto Alesina, Armando Miano, Stefanie Stantcheva. NBER Working Paper No. 24733. http://www.nber.org/papers/w24733

We design and conduct large-scale surveys and experiments in six countries to investigate how natives' perceptions of immigrants influence their preferences for redistribution. We find strikingly large biases in natives' perceptions of the number and characteristics of immigrants: in all countries, respondents greatly overestimate the total number of immigrants, think immigrants are culturally and religiously more distant from them, and are economically weaker – less educated, more unemployed, poorer, and more reliant on government transfers – than is the case. While all respondents have misperceptions, those with the largest ones are systematically the right-wing, the non-college educated, and the low-skilled working in immigration-intensive sectors. Support for redistribution is strongly correlated with the perceived composition of immigrants – their origin and economic contribution – rather than with the perceived share of immigrants per se. Given the very negative baseline views that respondents have of immigrants, simply making them think about immigration in a randomized manner makes them support less redistribution, including actual donations to charities. We also experimentally show respondents information about the true i) number, ii) origin, and iii) “hard work” of immigrants in their country. On its own, information on the “hard work” of immigrants generates more support for redistribution. However, if people are also prompted to think in detail about immigrants' characteristics, then none of these favorable information treatments manages to counteract their negative priors that generate lower support for redistribution.

None of the multitasking measures (accuracy, total time, total distance covered by the avatar, a prospective memory score, & a distractor management score) showed any sex differences

No sex difference in an everyday multitasking paradigm. Marco Hirnstein, Frank Larøi, Julien Laloyaux. Psychological Research, https://link.springer.com/article/10.1007/s00426-018-1045-0

Abstract: According to popular beliefs and anecdotes, females best males when handling multiple tasks at the same time. However, there is relatively little empirical evidence as to whether there truly is a sex difference in multitasking and the few available studies yield inconsistent findings. We present data from a paradigm that was specifically designed to test multitasking abilities in an everyday scenario, the computerized meeting preparation task (CMPT), which requires participants to prepare a room for a meeting and handling various tasks and distractors in the process. Eighty-two males and 66 females with a wide age range (18–60 years) and a wide educational background completed the CMPT. Results revealed that none of the multitasking measures (accuracy, total time, total distance covered by the avatar, a prospective memory score, and a distractor management score) showed any sex differences. All effect sizes were d ≤ 0.18 and thus not even considered “small” by conventional standards. The findings are in line with other studies that found no or only small gender differences in everyday multitasking abilities. However, there is still too little data available to conclude if, and in which multitasking paradigms, gender differences arise.

At variance with the honest signal hypothesis, vocal and facial attractiveness were uncorrelated, with the exception of a moderate positive correlation for vowels

Zäske, Romi, Verena G. Skuk, and Stefan R. Schweinberger. 2018. “Attractiveness and Distinctiveness in Voices and Faces of Young Adults.” PsyArXiv. June 29. doi:10.31234/osf.io/2avu3

Abstract: Facial attractiveness has been linked to the averageness (or typicality) of a face. More tentatively, it has also been linked to a speaker’s vocal attractiveness, via the “honest signal” hypothesis, holding that attractiveness signals good genes. In four experiments, we assessed ratings for attractiveness and two common measures of distinctiveness (“distinctiveness-in-thecrowd”- DITC and “deviation-based distinctiveness”-DEV) for faces and voices (vowels or sentences) from 64 young adult speakers (32 female). Consistent and strong negative correlations between attractiveness and DEV generally supported the averageness account of attractiveness for both voices and faces. By contrast, indicating that both measures of distinctiveness reflect different constructs, correlations between attractiveness and DITC were numerically positive for faces (though small and non-significant), and significant for voices in sentence stimuli. As the only exception, voice ratings based on vowels exhibited a moderate but significant negative correlation between attractiveness and DITC. Between faces and voices, distinctiveness ratings were uncorrelated. Remarkably, and at variance with the honest signal hypothesis, vocal and facial attractiveness were uncorrelated, with the exception of a moderate positive correlation for vowels. Overall, while our findings strongly support an averageness account of attractiveness for both domains, they provide little evidence for an honest signal account of facial and vocal attractiveness in complex naturalistic speech. Although our findings for vowels do not rule out the tentative notion that more primitive vocalizations can provide relevant clues to genetic fitness, researchers should carefully consider the nature of voice samples, and the degree to which these are representative of human vocal communication.

The so-called universal sex differences have been shown to be more pronounced in Western industrial societies than in most non-Western developing societies; a possible reason is less consanguineal marriages in the first group

Evolution, Societal Sexism, and Universal Average Sex Differences in Cognition and Behavior. Lee Ellis. In Oxford Handbook of Evolution, Biology, and Society, Edited by Rosemary L. Hopcroft, Apr 2018. DOI: 10.1093/oxfordhb/9780190299323.013.30

Abstract: During the past century, social scientists have documented many cross-cultural sex differences in personality and behavior, quite a few of which now appear to be found in all human societies. However, contrary to most scientists’ expectations, these so-called universal sex differences have been shown to be more pronounced in Western industrial societies than in most non-Western developing societies. This chapter briefly reviews the evidence bearing on these findings and offers a biologically based theory that could help shed light on why cross-cultural sex differences exist. The following hypothesis is offered: The expression of many genes influencing sexually dimorphic traits is more likely among descendants of couples who are least closely related to one another. If so, societies in which out-marriage is normative (i.e., Western industrial countries) will exhibit a stronger expression of genes for sexually dimorphic traits compared to societies in which consanguineal marriages are common.

Personality assimilation across species: enfacing an ape reduces own intelligence and increases emotion attribution to apes

Personality assimilation across species: enfacing an ape reduces own intelligence and increases emotion attribution to apes. Ke Ma. Roberta Sellaro, Bernhard Hommel. Psychological Research, https://link.springer.com/article/10.1007/s00426-018-1048-x

Abstract: Seeing another person’s face while that face and one’s own face are stroked synchronously or controlling a virtual face by moving one’s own induces the illusion that the other face has become a part of oneself—the enfacement effect. Here, we demonstrate that humans can enface even members of another species and that this enfacement promotes “feature migration” in terms of intelligence and emotional attribution from the representation of other to the representation of oneself, and vice versa. We presented participants with a virtual human face moving in or out of sync with their own face, and then morphed it into an ape face. Participants tended to perceive the ape face as their own in the sync condition, as indicated by body-ownership and inclusion-of-others-in-the-self ratings. More interestingly, synchrony also reduced performance in a fluid-intelligence task and increased the willingness to attribute emotions to apes. These observations, which fully replicated in another experiment, fit with the idea that self and other are represented in terms of feature codes, just like non-social events (as implied by the Theory of Event Coding), so that representational self–other overlap invites illusory conjunctions of features from one representation to the other.

Task in which responding sooner led to consistent, small rewards, and responding later led to larger rewards, but greater risk of gaining nothing: Males waited longer for the possibility of larger rewards, women responded sooner & consistently gain smaller rewards

Gender differences in preference for reward frequency versus reward magnitude in decision-making under uncertainty. Astin C. Cornwall, Kaileigh A. Byrne, Darrell A. Worthy. Personality and Individual Differences, Volume 135, 1 December 2018, Pages 40–44. https://doi.org/10.1016/j.paid.2018.06.031

Highlights
•    Participants performed an experience-based probabilistic intertemporal choice task.
•    Responding sooner led to consistent, small rewards.
•    Responding later led to larger rewards, but greater risk of gaining nothing.
•    Males preferred to wait longer for the possibility of larger rewards.
•    Females preferred to respond sooner and consistently gain smaller rewards.

Abstract: Extensive research has focused on gender differences in intertemporal choices made from description in which participants must choose from multiple options that are specified without ambiguity. However, there has been limited work examining gender differences in intertemporal choices made from experience in which the possible payoffs among choice alternatives are not initially known and can only be gained from experience. Other work suggests that females attend more to reward frequency, whereas males attend more to reward magnitude. However, the tasks used in this research have been complex and did not examine intertemporal decision-making. To specifically test whether females are more sensitive to reward frequency and males are more sensitive to reward magnitude on intertemporal decisions made from experience, we designed a simple choice task in which participants pressed a response button at a time of their own choosing on each of many trials. Faster responses led to smaller, but more frequent rewards, whereas slower responses led to larger, but less frequently given rewards. As predicted, females tended to respond quicker for more certain, smaller rewards than males, supporting our prediction that women attend more to reward frequency whereas men attend more to reward magnitude.

People inflate their earnings less when they use a foreign language; reason is a dual system account that suggests that self‐serving dishonesty is an automatic tendency, which is supported by a fast and intuitive system

Honesty Speaks a Second Language. Yoella Bereby‐Meyer et al. Topics in Cognitive Science, https://doi.org/10.1111/tops.12360

Abstract: Theories of dishonest behavior implicitly assume language independence. Here, we investigated this assumption by comparing lying by people using a foreign language versus their native tongue. Participants rolled a die and were paid according to the outcome they reported. Because the outcome was private, they could lie to inflate their profit without risk of repercussions. Participants performed the task either in their native language or in a foreign language. With native speakers of Hebrew, Korean, Spanish, and English, we discovered that, on average, people inflate their earnings less when they use a foreign language. The outcome is explained by a dual system account that suggests that self‐serving dishonesty is an automatic tendency, which is supported by a fast and intuitive system. Because using a foreign language is less intuitive and automatic, it might engage more deliberation and reduce the temptation to lie. These findings challenge theories of ethical behavior to account for the role of the language in shaping ethical behavior.

Impact of the menstrual cycle on women’s engagement in activities that could negatively affect their health, including sexual behavior & alcohol & tobacco consumption, as well as their ability to recognize & avoid potentially threatening people & situations

Do Women Expose Themselves to more Health-Related Risks in Certain Phases of the Menstrual Cycle? A Meta-analytic Review. Jordane Boudesseul, Kelly A. Gildersleeve, Martie Haselton, Laurent Bègue. July 02, 2018. https://psyarxiv.com/k8s5y/

Abstract: Over the past three decades, researchers have increasingly examined the menstrual cycle as a potential source of day-to-day variation in women’s cognitions, motivations, and behavior. Within this literature, several lines of research have examined the impact of the menstrual cycle on women’s engagement in activities that could negatively affect their health, including sexual behavior and alcohol and tobacco consumption, as well as their ability to recognize and avoid potentially threatening people and situations. However, findings have been mixed, leaving it unclear whether women may expose themselves to more health-related risks during certain phases of the cycle. To address this question, we conducted a meta-analysis of 23 published and 4 unpublished studies (N = 7,527). The meta-analysis revealed some shifts across the menstrual cycle in women’s sexual behavior and risk recognition and avoidance, whereas patterns were less clear for alcohol and cigarette consumption. These findings help to clarify the proximate physiological and evolutionary mechanisms underlying women’s health-related risk-taking and may inform new interventions.

Clinical & informal sperm donation markets: Factors that impact female’s decision to choose specific donors, and the characteristics, personality and behaviour of males who choose to donate

Decision-making in mate choice markets. Stephen Whyte. Submitted in fulfilment of the requirements for Doctor of Philosophy (Economics), School of Economics & Finance. Queensland University of Technology, https://eprints.qut.edu.au/118622/2/Stephen_Whyte_Thesis.pdf

Abstract: This thesis contributes to the behavioural economic and behavioural science  literature by providing empirical evidence of factors that  impact  large scale decision making in mate choice settings. The thesis consists of five studies. The first three explore human decision making in the online dating market. They utilise both stated preference and actual decision outcomes to explore differences between preference and choice, positive assortment, and specificity of preference for different sexes. Studies four and five concern male and female behaviour in the clinical and informal (online) sperm donation markets. These studies explore factors that impact female’s decision to choose specific donors, and the characteristics, personality and behaviour of males who choose to donate.

58.4% of the sampled women experienced a more intense orgasm depending on their partner’s ejaculation intensity (loud moaning, strong thrusting), but 65.1% did not experience a more intense orgasm depending on the subjectively assessed ejaculation volume

The importance of male ejaculation for female sexual satisfaction and orgasm ability. A. Burri1, J. Buchmeier2, H. Porst. The Journal of Sexual Medicine, Volume 15, Issue 7, Supplement 3, July 2018, Pages S123, Proceedings of the 21st World Meeting on Sexual Medicine. https://doi.org/10.1016/j.jsxm.2018.04.005

Objective: Previous research has shown that female sexual functioning and overall relationship quality is also in fluenced by the partner’s sexual problems such as premature ejaculation (PE). Therefore, the aim of the study was to assess the importance of intravaginal ejaculation characteristics including as subjectively assessed ejaculation intensity and ejaculation volume and its importance for female sexual satisfaction (FSS) and female orgasm ability.

Material and Methods: A total of N = 245 women between 18 and 75 years meeting the criteria of “previous experience of sexual activity” and “absence of a sexual pain disorder” were included in this cross-sectional online study. Validated questionnaires were administered to assess the relevant study information. Furthermore, a study-specific, self-constructed questionnaire consisting of 29 items asking about women’s sexual and ejaculatory preferences (items responded to on a 5 to 7-pointed Likert-type scale). Relationships between the variables of interest were investigated using partial Spearman correlations controlling for age.

Results:
1) Women with a high orgasmic ability considered the ejaculation during intercourse to be more important than women with a low orgasmic ability (rs = 0.15, p < 0.05).

2) Women subjectively reporting minor problems regarding their male partner’s ejaculatory characteristics were more sexually satisfied than women reporting major problems.

3) 56.6% of the women said they experienced a more intense orgasm depending on their
partner’s presence of ejaculation.

4) 29.4% of the women never focused on the ejaculation volume during intercourse and 65.1% did not experience a more intense orgasm depending on the subjectively assessed ejaculation volume.

5) 58.4% of the sampled women experienced a more intense orgasm depending on their partner’s ejaculation intensity (loud moaning, strong thrusting).

6) No significant difference regarding the importance of ejaculation was detected between women preferring intra-vaginal intercourse and women preferring other sexual activities (p > 0.05).

Conclusions: The findings provide insight to importance and perception of different ejaculation aspects and their association with the female partner’s sexual function and satisfaction. The results have clinical relevance, as the treatment of ejaculatory dysfunctions should consider a stronger involvement of the the female partner.

Women: Sexual conservatism, rather than age, predicted more unpleasantness attributed to the pictures; findings point to the use of erotica as aviable tool aimed at increasing women’s subjective sexual arousal, including in older ages

003 Effects of age on the subjective sexual response and emotional appraisal of sex pictures in women. J. Carvalho, L. Ferreira, R. Rico, I.M. Santos. The Journal of Sexual Medicine. Volume 15, Issue 7, Supplement 3, July 2018, Pages S124, Proceedings of the 21st World Meeting on Sexual Medicine. https://doi.org/10.1016/j.jsxm.2018.04.007

Objective(s): Age is expected to influence women’s sexual functioning and behavior, not only due its impact at the organic level, but also given the strong cohort effects that shape women’s beliefs regarding sexuality and relationships. However, most of the current assumptions about the effects of age in women’s sexual response and behavior, relate to the influence of health issues on the propensity for sexual difficulties. Indeed, broader aspects such as sexual and relationship satisfaction, have only recently fallen under the scope of scientific research. Similarly, other aspects relating to the appraisal of sexual contents by older women have been completely dismissed. Accordingly, the aim of the current study was to test the effect of age on the sexual and emotional responses to sex stimuli, as well as to test the adding effects of women’s beliefs regarding sexuality, on the appraisal of these stimuli.

Material and Method(s): Seventy-three heterosexual women, ranging from 18-77 years old, were exposed to a series of romantic, sexually moderate and sexually explicit pictures in a laboratorial context. Women reported on the levels of emotional valence, subjective sexual arousal, and level of sexual content attributed to the pictures in each set. Additionally, women completed a self-report questionnaire aimed at measuring women’s beliefs regarding female sexuality.

Result(s): Findings from hierarchical regression analyses (age entered at step 1 and sexual beliefs entered at step 2) revealed that age did not predict the emotional valence attributed to the sexual pictures; instead, sexual conservatism predicted more unpleasantness attributed to the s exually explicit pictures. Also, age predicted higher levels of subjective sexual arousal to all types of pictures and was further related to the appraisal of romantic and sexually moderate pictures as being more “sexual

Conclusion(s): Contrary to some myths supporting the negative effects of age on women's sexuality, the current results have shown that age was actually a significant (positive) predictor of subjective sexual arousal to all types of pictures (romantic, sexually moderate and sexually explicit pictures), and did not have a negative effect on the emotional valence attributed to the sex pictures. Indeed, sexual conservatism, rather than age, predicted more unpleasantness attributed to the pictures. Accordingly, findings point to the use of erotica as aviable tool aimed at increasing women’s subjective sexual arousal, including in older ages, while sexual beliefs should be monitored at all ages.

Does Partisan Self-interest Dictate Support for Election Reform? It Does. Experimental Evidence on the Willingness of Citizens to Alter the Costs of Voting for Electoral Gain

Does Partisan Self-interest Dictate Support for Election Reform? Experimental Evidence on the Willingness of Citizens to Alter the Costs of Voting for Electoral Gain. Daniel R. Biggers. Political Behavior, https://doi.org/10.1007/s11109-018-9481-5

Abstract: Elite support for modifying electoral institutions and policies generally depends on whether a proposed change is expected to improve their party’s electoral prospects. Prior studies suggest that the average citizen evaluates potential reforms in a similar manner, but they fail to directly demonstrate that individuals actually consider their partisan self-interest when forming policy preferences. I address this limitation through two survey experiments that manipulate the specific group for whom reforms make voting more or less difficult. The results provide strong causal evidence that individuals update their attitudes as expected in response to that information. Members of both parties consistently express greater support for changes when framed as advancing their party’s electoral prospects than when characterized as benefiting their opponents. The findings have important implications for the constraints faced by political actors in gaming the electoral system in their favor and for understanding the role of self-interest in shaping policy attitudes.

Recent findings from both human neuroimaging and animal electrophysiology have revealed that prior expectations can either damp the sensory representation or enhance it via a process of sharpening.

How Do Expectations Shape Perception? Floris P. de Lange, Micha Heilbron, Peter Kok. Trends in Cognitive Sciences, https://doi.org/10.1016/j.tics.2018.06.002

Highlights

Expectations play a strong role in determining the way we perceive the world.

Prior expectations can originate from multiple sources of information, and correspondingly have different neural sources, depending on where in the brain the relevant prior knowledge is stored.

Recent findings from both human neuroimaging and animal electrophysiology have revealed that prior expectations can modulate sensory processing at both early and late stages, and both before and after stimulus onset. The response modulation can take the form of either dampening the sensory representation or enhancing it via a process of sharpening.

Theoretical computational frameworks of neural sensory processing aim to explain how the probabilistic integration of prior expectations and sensory inputs results in perception.

Abstract: Perception and perceptual decision-making are strongly facilitated by prior knowledge about the probabilistic structure of the world. While the computational benefits of using prior expectation in perception are clear, there are myriad ways in which this computation can be realized. We review here recent advances in our understanding of the neural sources and targets of expectations in perception. Furthermore, we discuss Bayesian theories of perception that prescribe how an agent should integrate prior knowledge and sensory information, and investigate how current and future empirical data can inform and constrain computational frameworks that implement such probabilistic integration in perception.

Benevolent Sexism and Mate Preferences: Why Do Women Prefer Benevolent Men Despite Recognizing That They Can Be Undermining?

Benevolent Sexism and Mate Preferences: Why Do Women Prefer Benevolent Men Despite Recognizing That They Can Be Undermining? Pelin Gul et al. Personality and Social Psychology Bulletin, https://doi.org/10.1177/0146167218781000

Abstract: Benevolent sexism (BS) has detrimental effects on women, yet women prefer men with BS attitudes over those without. The predominant explanation for this paradox is that women respond to the superficially positive appearance of BS without being aware of its subtly harmful effects. We propose an alternative explanation drawn from evolutionary and sociocultural theories on mate preferences: Women find BS men attractive because BS attitudes and behaviors signal that a man is willing to invest. Five studies showed that women prefer men with BS attitudes (Studies 1a, 1b, and 3) and behaviors (Studies 2a and 2b), especially in mating contexts, because BS mates are perceived as willing to invest (protect, provide, and commit). Women preferred BS men despite also perceiving them as patronizing and undermining. These findings extend understanding of women’s motives for endorsing BS and suggest that women prefer BS men despite having awareness of the harmful consequences.

Sexual identities & participation in liberal & conservative social movements: the greater activism of gays and lesbians also crossed over to recent Occupy Wall Street, peace, & environmental mobilizations

Sexual identities and participation in liberal and conservative social movements. Eric Swank. Social Science Research, Volume 74, August 2018, Pages 176-186. https://doi.org/10.1016/j.ssresearch.2018.04.002

Abstract: The desire for social change, political activism, and sexual identities may all be related. Lesbians and gays generally contest heterosexism more than heterosexuals but we do not know how sexual identities sways participation in class, race, and gender based social movements. When analyzing the American National Election Surveys of 2012 (n = 3519), gays and lesbians were about twenty times more likely to join LGB justice campaigns than heterosexuals. Moreover, the greater activism of gays and lesbians also crossed over to recent Occupy Wall Street, peace, and environmental mobilizations. Finally, this analysis ends with logistic regressions that determine if any sexual identity gaps in movement participation are the result of demographic, contextual, and ideological covariates.

People often respond to decreases in the prevalence of a stimulus by expanding their concept of it. This “prevalence-induced concept change” occurred even when participants were forewarned about it and even when they were instructed and paid to resist it.

Prevalence-induced concept change in human judgment. David E. Levari et al. Science  Jun 29 2018: Vol. 360, Issue 6396, pp. 1465-1467. DOI: 10.1126/science.aap8731

Perceptual and judgment creep: Do we think that a problem persists even when it has become less frequent? Levari et al. show experimentally that when the “signal” a person is searching for becomes rare, the person naturally responds by broadening his or her definition of the signal—and therefore continues to find it even when it is not there. From low-level perception of color to higher-level judgments of ethics, there is a robust tendency for perceptual and judgmental standards to “creep” when they ought not to. For example, when blue dots become rare, participants start calling purple dots blue, and when threatening faces become rare, participants start calling neutral faces threatening. This phenomenon has broad implications that may help explain why people whose job is to find and eliminate problems in the world often cannot tell when their work is done.

Abstract: Why do some social problems seem so intractable? In a series of experiments, we show that people often respond to decreases in the prevalence of a stimulus by expanding their concept of it. When blue dots became rare, participants began to see purple dots as blue; when threatening faces became rare, participants began to see neutral faces as threatening; and when unethical requests became rare, participants began to see innocuous requests as unethical. This “prevalence-induced concept change” occurred even when participants were forewarned about it and even when they were instructed and paid to resist it. Social problems may seem intractable in part because reductions in their prevalence lead people to see more of them.

Self-reported Addiction to Pornography in a Nationally Representative Sample: The Role of Religiousness and Morality

Grubbs, Joshua, Shane W. Kraus, and Samuel Perry. 2018. “Self-reported Addiction to Pornography in a Nationally Representative Sample: The Role of Religiousness and Morality.” PsyArXiv. June 29. doi:10.17605/OSF.IO/M94NK

Abstract

Background and Aims: Despite controversies regarding its existence as a legitimate mental health condition, self-reported pornography addiction is known to occur regularly. In the United States, prior works using various sampling techniques, such as undergraduate samples and online convenience samples, have consistently demonstrated that a number of pornography users report feeling dysregulated or out of control in their use. Even so, there has been very little work in U.S. nationally representative samples to examine self-reported pornography addiction.

Methods: The present study sought to examine self-reported pornography addiction in a U.S. nationally representative sample of adult internet users (N=2,075).

Results:  Results indicated that the majority of the sample had viewed pornography within their lifetimes (n = 1,466), with just over half reporting some use in the past year (n = 1,056).  Moreover, roughly 11% of men and 3% of women reported some agreement with feelings of pornography addiction. Across all participants, such feelings were most strongly associated with male gender, younger age, greater religiousness, greater moral incongruence regarding pornography use, and greater use of pornography.

Discussion and Conclusions: Collectively, these findings are consistent with prior works that have noted that self-reported pornography addiction is a complex phenomenon that is predicted by both objective behavior and subjective moral evaluations of that behavior.

Between 1800 & 2000, for both genders, adjectives related to agreeableness were used most often and those related to neuroticism least often. The usage frequency of agreeableness declined, whereas extraversion & openness showed increases

How Have Males and Females Been Described Over the Past Two Centuries? An Analysis of Big-Five Personality-related adjectives in the Google English Books. Shenglu Yea et al. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2018.06.007

Highlights
•    Agreeableness was described most often for both men and women.
•    Positive personality words were used more often than negative words for all factors.
•    The usage frequencies were higher for men than women for four factors except openness.
•    Gender differences showed some reduction over time.

Abstract: Using the American corpus and the English fiction corpus from Google Books databases, this study examined the frequencies of Big-Five personality adjectives used to describe the two genders between 1800 and 2000. Both gender similarities and differences were found. For both genders, adjectives related to agreeableness were used most often and those related to neuroticism least often. The usage frequency of agreeableness showed a steady decline, whereas extraversion and openness (and, to some extent, neuroticism) showed increases first and then leveled off. In terms of gender differences, the overall frequencies were higher for men than women for agreeableness, extraversion, conscientiousness, and neuroticism, but there was no gender difference for openness. Gender differences showed some reduction over time.

Odor awareness: A model including individual-level predictors (gender, age, material situation, education & preferred social distance) provided a relatively good fit to the data, but adding country-level predictors did not

Global study of social odor awareness. Agnieszka Sorokowska Agata et al. Chemical Senses, bjy038, https://doi.org/10.1093/chemse/bjy038

Abstract: Olfaction plays an important role in human social communication, including multiple domains in which people often rely on their sense of smell in the social context. The importance of the sense of smell and its role can however vary inter-individually and culturally. Despite the growing body of literature on differences in olfactory performance or hedonic preferences across the globe, the aspects of a given culture as well as culturally universal individual differences affecting odor awareness in human social life remain unknown. Here, we conducted a large-scale analysis of data collected from 10,794 participants from 52 study sites from 44 countries all over the world. The aim of our research was to explore the potential individual and country-level correlates of odor awareness in the social context. The results show that the individual characteristics were more strongly related than country-level factors to self-reported odor awareness in different social contexts. A model including individual-level predictors (gender, age, material situation, education and preferred social distance) provided a relatively good fit to the data, but adding country-level predictors (Human Development Index, population density and average temperature) did not improve model parameters. Although there were some cross-cultural differences in social odor awareness, the main differentiating role was played by the individual differences. This suggests that people living in different cultures and different climate conditions may still share some similar patterns of odor awareness if they share other individual-level characteristics.

We reveal that mobility patterns evolve significantly yet smoothly, and that the number of familiar locations an individual visits at any point is a conserved quantity with a typical size of ~25

Evidence for a conserved quantity in human mobility. Laura Alessandretti, Piotr Sapiezynski, Vedran Sekara, Sune Lehmann & Andrea Baronchelli. Nature Human Behaviour, https://www.nature.com/articles/s41562-018-0364-x

Abstract: Recent seminal works on human mobility have shown that individuals constantly exploit a small set of repeatedly visited locations1,2,3. A concurrent study has emphasized the explorative nature of human behaviour, showing that the number of visited places grows steadily over time4,5,6,7. How to reconcile these seemingly contradicting facts remains an open question. Here, we analyse high-resolution multi-year traces of ~40,000 individuals from 4 datasets and show that this tension vanishes when the long-term evolution of mobility patterns is considered. We reveal that mobility patterns evolve significantly yet smoothly, and that the number of familiar locations an individual visits at any point is a conserved quantity with a typical size of ~25. We use this finding to improve state-of-the-art modelling of human mobility4,8. Furthermore, shifting the attention from aggregated quantities to individual behaviour, we show that the size of an individual’s set of preferred locations correlates with their number of social interactions. This result suggests a connection between the conserved quantity we identify, which as we show cannot be understood purely on the basis of time constraints, and the ‘Dunbar number’9,10 describing a cognitive upper limit to an individual’s number of social relations. We anticipate that our work will spark further research linking the study of human mobility and the cognitive and behavioural sciences.

The Proportion of Sexual Offenders Who Are Female Is Higher Than Thought: A Meta-Analysis

The Proportion of Sexual Offenders Who Are Female Is Higher Than Thought: A Meta-Analysis. Franca Cortoni et al. Criminal Justice and Behavior, https://doi.org/10.1177/0093854816658923

Abstract: Women commit sexual offenses, but the proportion of sexual offenders who are female is subject to debates. Based on 17 samples from 12 countries, the current meta-analysis found that a small proportion of sexual offenses reported to police are committed by females (fixed-effect meta-analytical average = 2.2%). In contrast, victimization surveys indicated prevalence rates of female sexual offenders that were six times higher than official data (fixed-effect meta-analytical average = 11.6%). Female sexual offenders are more common among juvenile offenders than adult offenders, with approximately 2 percentage points more female juvenile sex offenders than female adult sex offenders. We also found that males were much more likely to self-report being victimized by female sex offenders compared with females (40% vs. 4%). The current study provides a robust estimate of the prevalence of female sexual offending, using a large sample of sexual offenses across diverse countries.

The Association Between Fraternal Birth Order and Anal-Erotic Roles of Men Who Have Sex with Men: Bottoms had a significantly greater mean number of older brothers than did Not-Bottoms

The Association Between Fraternal Birth Order and Anal-Erotic Roles of Men Who Have Sex with Men. Charles H. Wampold. Archives of Sexual Behavior, https://link.springer.com/article/10.1007/s10508-018-1237-0

Abstract: The fraternal birth order effect (FBOE) describes the phenomenon that homosexual men tend to have a greater number of older brothers than do heterosexual men. The FBOE is a marker for an innate, biological predisposition for androphilia in genotypic males. The FBOE has been studied since the 1930s and is the most consistent biodemographic correlate of sexual orientation in men. This study sought to determine whether the FBOE applies equally to all men who have sex with men (MSM), or disproportionately to MSM whose anal intercourse behavior is predominantly receptive (Bottoms). Participants included 243 North American adult MSM who responded to advertisements posted on a Web site and other electronic media associated with the GALA festival, a quadrennial gathering of gay and lesbian choruses. Each was asked whether his anal intercourse behavior during the preceding year was predominantly receptive, predominantly penetrative, or about equally receptive and penetrative. Those who indicated their behavior was predominantly receptive were coded “Bottoms”; all others were coded “Not-Bottoms.” Participants were also surveyed as to their sibship composition. Bottoms had a significantly greater mean number of older brothers than did Not-Bottoms. There was no significant difference with respect to older or younger sisters or younger brothers. Further, the older sibling sex ratio (OSSR) for the Bottom cohort, but not for the Not-Bottom cohort, was significantly higher than the expected OSSR for the general male population (OSSR = No. older brothers/No. older sisters × 100; expected OSSR for general population = 106). Thus, late fraternal birth order was correlated with receptive anal-erotic behavior among MSM.

Are some people truly better able to accurately perceive the personality of others? Previous research suggests that the good judge may be of little practical importance and individual differences minimal

Rogers, K. H., & Biesanz, J. C. (2018). Reassessing the good judge of personality. Journal of Personality and Social Psychology. Advance online publication. http://dx.doi.org/10.1037/pspp0000197

Abstract: Are some people truly better able to accurately perceive the personality of others? Previous research suggests that the good judge may be of little practical importance and individual differences minimal. In four large samples we assessed whether expressive accuracy (the good target) is a necessary condition for perceptive accuracy (the good judge) to emerge. As predicted from Funder’s (1995) realistic accuracy model, assessments of the good judge predicted increased impression accuracy in the context of judgments of the good target. In contrast, evaluative tendencies for judges did not evidence a similar interaction; the positivity of impressions did not reliably increase as a function of how positively targets tend to be viewed. The present results suggest the good judge does indeed exist—some individuals are much better able to detect and utilize valid cues from targets—but this is only strongly evident when perceiving a good target.

Witchcraft beliefs in early modern Europe: Memes, or parasites of the mind

Parasites of the Mind. Why Cultural Theorists Need the Meme’s Eye View. Maarten Boudry, Steije Hofhuis. Cognitive Systems Research, https://doi.org/10.1016/j.cogsys.2018.06.010

Abstract: Are there any such things as mind parasites? By analogy with biological parasites, such cultural items are supposed to subvert or harm the interests of their host. The hypothesis of cultural parasitism has appeared in different guises in the burgeoning field of cultural evolution. To unpack the notion of mind parasites, we first clear some conceptual ground around the concept of cultural adaptation and its relation to human agency. We then formulate Millikan’s challenge: how can cultural items develop novel purposes of their own, cross-cutting or subverting our own personal purposes? If this central challenge is not met, talk of cultural ‘parasites’ or ‘selfish memes’ remains vacuous. First, we discuss why other attempts to answer Millikan’s challenge have failed. In particular, we put to rest the claims of panmemetics, a somewhat sinister worldview according to which human culture is nothing more than a swarm of selfish agents, plotting and scheming behind the scenes. Next, we reject a more reasonable, but still overly permissive approach to mind parasites, which equates them with biologically maladaptive culture. Finally, we present our own answer to Millikan’s challenge: certain systems of misbelief can be fruitfully treated as cultural parasites, which are designed by cultural evolution and which subvert the interests of their human hosts. As a proof of concept, we discuss witchcraft beliefs in early modern Europe, and show how the meme’s eye view promises to shed new light on a mystery that historians and social scientists have been wrestling with for decades.

87% of husbands and 49% of wives reported consistently experiencing orgasm. 43% of husbands misperceived how often their wives experienced orgasm; wives' sexual satisfaction was positively associated with self-reported orgasm frequency, & both wives' and husbands' sexual communication

The Significance of the Female Orgasm: A Nationally Representative, Dyadic Study of Newlyweds' Orgasm Experience. Nathan D. Leonhardt et al. Leonhardt ND, Willoughby BJ, Busby DM, et al. The Journal of Sexual Medicine 2018;XX:XXX–XXX. https://doi.org/10.1016/j.jsxm.2018.05.018

Abstract

Background: Self-reported orgasm, perception of partner's orgasm, and misperception of partner's orgasm have each been correlated with individual sexual and relationship satisfaction, but these associations have rarely included dyadic data, have not fully accounted for potentially confounding variables such as sexual communication, and have never been simultaneously studied with a nationally representative sample.

Aim: To provide a more complete picture of how the orgasmic experience within the heterosexual couple influences individual and partner sexual and relationship satisfaction.

Methods: Using a nationally representative dyadic sample of 1,683 newlywed heterosexual couples, a structural equation model was estimated to test associations between husband and wife self-reported orgasm frequency, husband and wife report of the other partner's orgasm frequency, and husband and wife misperception of their partner's orgasm frequency, as correlates of relationship and sexual satisfaction.

Outcomes: Both husband and wife completed the Couples Satisfaction Index to assess their own relationship satisfaction, and completed a sexual satisfaction instrument designed for the CREATE study.

Results: 87% of husbands and 49% of wives reported consistently experiencing orgasm. 43% of husbands misperceived how often their wives experienced orgasm. The final structural equation model, including sexual communication, explained moderate amounts of variance in wives' and husbands' relationship satisfaction, and a high level of variance for wives' and husbands' sexual satisfaction. Wives' relationship satisfaction was positively associated with wives' and husbands' sexual communication. Wives' sexual satisfaction was positively associated with self-reported orgasm frequency, and both wives' and husbands' sexual communication. Husbands' relationship satisfaction was positively associated with husbands' and wives' sexual communication. Husbands' sexual satisfaction was positively associated with husbands' perception of wives' orgasm frequency, and both husbands' and wives' sexual communication.

Clinical Translation: When counseling couples, clinicians should give particular attention to the wife's orgasm experiences, to potentially help both husbands and wives have higher sexual satisfaction.

Strengths & Limitations: Strengths of this study include the use of a nationally representative sample and dyadic data. Limitations include cross-sectional data, and the assessment of sexual experiences only in newlywed couples.

Conclusion: Wives' orgasm (wives' self-report of frequency and husbands' perception of frequency) has a unique positive association with sexual satisfaction, even after taking into account other aspects of the orgasm experience and sexual communication.

Highlights
•    We examine whether, and to what extent, cognitive abilities matter for the subjective well-being of older individuals
•    We utilize unique panel data from SHARE on individuals aged 50+
•    We find that individuals with higher cognitive abilities have, on average, higher levels of well-being
•    The beneficial effect of cognitive ability is more pronounced when it comes to the CASP measure as opposed to life satisfaction
•    The current paper provides some of the first empirical evidence on the relationship between cognition and well-being of older individuals in Europe

Abstract: In this paper we study the importance of cognitive abilities for the subjective well-being of older individuals. We draw unique panel data from the Survey of Health, Ageing and Retirement in Europe (SHARE) on a representative sample of individuals aged 50+. The analysis reveals that individuals with higher cognitive abilities have, on average, higher levels of subjective well-being. The result holds for two different well-being measures and remains robust under different specifications and limitations on the data. As such, it provides some of the first empirical evidence on the relationship between cognition and subjective well-being of older individuals in Europe.

Race and economic opportunity in the United States: Summary

Race and economic opportunity in the United States. Raj Chetty, Nathaniel Hendren, Maggie R. Jones, Sonya R. Porter. Vox, Jun 27 2018. https://voxeu.org/article/race-and-economic-opportunity-united-states

The sources of racial disparities in income have been debated for decades. This column uses data on 20 million children and their parents to show how racial disparities persist across generations in the US. For instance, black men have much lower chances of climbing the income ladder than white men even if they grow up on the same block. In contrast, black and white women have similar rates of mobility. The column discusses how such findings can be used to reduce racial disparities going forward.

Finding #1: Hispanic Americans are moving up in the income distribution across generations, while Black Americans and American Indians are not.

Finding #2: The black.white income gap is entirely driven by differences in men's, not women's, outcomes.

Finding #3: Differences in family characteristics (parental marriage rates, education, wealth) and differences in ability explain very little of the black.white gap.

Finding #4: In 99% of neighbourhoods in the United States, black boys earn less in adulthood than white boys who grow up in families with comparable income.

Finding #5: Both black and white boys have better outcomes in low-poverty areas, but black-white gaps are bigger in such neighbourhoods.

Finding #6: Within low-poverty areas, black.white gaps are smallest in places with low levels of racial bias among whites and high rates of father presence among blacks.

Finding #7: The black.white gap is not immutable: black boys who move to better neighbourhoods as children have significantly better outcomes.

Ethnolinguistic Favoritism in African Politics: Ethnic favoritism is more widespread than previously believed, finding that patronage tends to be targeted toward ethnic regions rather than individuals of a particular ethnic group

Dickens, Andrew. 2018. "Ethnolinguistic Favoritism in African Politics." American Economic Journal: Applied Economics, 10(3):370-402. DOI: 10.1257/app.20160066

Abstract: African political leaders have a tendency to favor members of their own ethnic group. Yet for all other ethnic groups in a country, it is unclear whether having a similar ethnicity to the leader is beneficial. To shed light on this issue, I use a continuous measure of linguistic similarity to quantify the ethnic similarity of a leader to all ethnic groups in a country. Combined with panel data on 163 ethnic groups partitioned across 35 sub-Saharan countries, I use within-group time variation in similarity that results from a partitioned group's concurrent exposure to multiple national leaders. Findings show that ethnic favoritism is more widespread than previously believed: in addition to evidence of coethnic favoritism, I document evidence of non-coethnic favoritism that typically goes undetected in the absence of a continuous measure of similarity. I also find that patronage tends to be targeted toward ethnic regions rather than individuals of a particular ethnic group. I relate these results to the literature on coalition building, and provide evidence that ethnicity is one of the guiding principles behind high-level government appointments.

Stanford Prison Experiment: Using recordings from the archive we show how the experimenters directly intervened to persuade Guards to adopt their roles and to act tough

Van Bavel, Jay J. 2018. “Rethinking the ‘nature’ of Brutality: Uncovering the Role of Identity Leadership in the Stanford Prison Experiment.” PsyArXiv. June 27. doi:10.17605/OSF.IO/B7CRX

Abstract: On the basis of findings from the Stanford Prison Experiment (SPE), Zimbardo and colleagues (e.g., Haney, Banks & Zimbardo, 1973) have argued that people’s willingness to oppress others — whether in the world at large or in classic social psychological studies — is the result of a tendency to conform ‘naturally’ to brutal roles. In contrast, Haslam and Reicher (e.g., 2007) have argued that it results from leadership which encourages potential perpetrators to identify with what is presented as a noble ingroup cause and to see their actions as necessary for the advancement of that cause. We review a range of evidence to show that such an analysis explains other classic studies of toxic behaviour (e.g. Milgram’s obedience studies). Nevertheless, researchers have hitherto had limited capacity to establish whether analysis framed in terms of identity leadership can account for brutality in the SPE. This has changed following the recent digitization of the SPE archive. Using recordings from the archive we show how the experimenters directly intervened to persuade Guards to adopt their roles and to act tough. Moreover, we show how these interventions accord with the tenets of identity leadership. Implications for the analysis of conformity, the understanding of brutality and the interpretation of the SPE are discussed.

Sex, trait psychopathy, and trait sadism were significant predictors of a short-term mating orientation. For long-term mating orientations, there was no predictive utility of sex, but there were positive associations for narcissism & negative associations for psychopathy & sadism

Predicting Short- and Long-Term Mating Orientations: The Role of Sex and the Dark Tetrad. Alexandra Tsoukas & Evita March. The Journal of Sex Research, https://doi.org/10.1080/00224499.2017.1420750

Abstract: Previous literature has extensively considered factors that influence short- and long-term mating orientations, with specific attention given to individual differences (e.g., sex and personality). Although research has established the role “darker” personality traits (i.e., the dark triad) play in mating orientation, this triad has recently been reconceptualized as a tetrad. Due to this reconceptualization, the current study sought to establish the utility of sex and the dark tetrad in predicting individual short- and long-term mating orientations. In addition, as an alternative to previous methodology, the orientations were assessed using a continuous measure. A total of 464 participants, ages 18 to 69, completed an online questionnaire assessing dark tetrad traits and mating orientations. Results showed that sex, trait psychopathy, and trait sadism were significant predictors of a short-term mating orientation. For long-term mating orientations, there was no predictive utility of sex, but there were positive associations for narcissism and negative associations for psychopathy and sadism. These findings add further understanding of the predictors of mating orientation and the utility of the tetrad in predicting mating orientations. In addition, the findings offer future mating orientation studies an alternative measure to the traditional dichotomous format.

Cognition, emotion and reward networks associated with sex differences for romantic appraisals: men and women differ in the processing of romantic information and that it may be more effortful for men to perceive and evaluate romance degree

Cognition, emotion and reward networks associated with sex differences for romantic appraisals. Jie Yin, Zhiling Zou, Hongwen Song, Zhuo Zhang, Bo Yang & Xiting Huang. Scientific Reports, volume 8, Article number: 2835 (2018). https://www.nature.com/articles/s41598-018-21079-5

Abstract: Romantic love is a cross-culturally universal phenomenon that serves as a commitment device for motivating pair bonding in human beings. Women and men may experience different feelings when viewing the same warm, romantic scenes. To determine which brain systems may be involved in romance perception and examine possible sex differences, we scanned 16 women and 16 men who were intensely in love, using functional MRI. Participants were required to rate the romance level of 60 pictures showing romantic events that may frequently occur during romantic relationship formation. The results showed that greater brain activation was found for men in the insula, PCC (posterior cingulate cortex), and prefrontal gyrus compared with women, primarily under the High-romance condition. In addition, enhanced functional connectivity between the brain regions involved in the High-romance condition in contrast to the Low-romance condition was only found for men. These data suggest that men and women differ in the processing of romantic information and that it may be  more effortful for men to perceive and evaluate romance degree.

Most taxa lack well-developed sexual weaponry; females of only a few species possess better weapons than males; & animals possessing the most developed weapons have non‐hunting habits or are faunivores that prey on very small prey relative to their body size

Intrasexually selected weapons. Alejandro Rico‐Guevara, Kristiina J. Hurme. Biological Reviews, https://doi.org/10.1111/brv.12436

ABSTRACT: We propose a practical concept that distinguishes the particular kind of weaponry that has evolved to be used in combat between individuals of the same species and sex, which we term intrasexually selected weapons (ISWs). We present a treatise of ISWs in nature, aiming to understand their distinction and evolution from other secondary sex traits, including from ‘sexually selected weapons’, and from sexually dimorphic and monomorphic weaponry. We focus on the subset of secondary sex traits that are the result of same‐sex combat, defined here as ISWs, provide not previously reported evolutionary patterns, and offer hypotheses to answer questions such as: why have only some species evolved weapons to fight for the opposite sex or breeding resources? We examined traits that seem to have evolved as ISWs in the entire animal phylogeny, restricting the classification of ISW to traits that are only present or enlarged in adults of one of the sexes, and are used as weapons during intrasexual fights. Because of the absence of behavioural data and, in many cases, lack of sexually discriminated series from juveniles to adults, we exclude the fossil record from this review. We merge morphological, ontogenetic, and behavioural information, and for the first time thoroughly review the tree of life to identify separate evolution of ISWs. We found that ISWs are only found in bilateral animals, appearing independently in nematodes, various groups of arthropods, and vertebrates. Our review sets a reference point to explore other taxa that we identify with potential ISWs for which behavioural or morphological studies are warranted. We establish that most ISWs come in pairs, are located in or near the head, are endo‐ or exoskeletal modifications, are overdeveloped structures compared with those found in females, are modified feeding structures and/or locomotor appendages, are most common in terrestrial taxa, are frequently used to guard females, territories, or both, and are also used in signalling displays to deter rivals and/or attract females. We also found that most taxa lack ISWs, that females of only a few species possess better‐developed weapons than males, that the cases of independent evolution of ISWs are not evenly distributed across the phylogeny, and that animals possessing the most developed ISWs have non‐hunting habits (e.g. herbivores) or are faunivores that prey on very small prey relative to their body size (e.g. insectivores). Bringing together perspectives from studies on a variety of taxa, we conceptualize that there are five ways in which a sexually dimorphic trait, apart from the primary sex traits, can be fixed: sexual selection, fecundity selection, parental role division, differential niche occupation between the sexes, and interference competition. We discuss these trends and the factors involved in the evolution of intrasexually selected weaponry in nature.

Moral character of similar persons (in social beliefs) was perceived as much higher than that of dissimilar ones (effect was large); similar persons were perceived as more trustworthy than dissimilar ones (also large effect)

The mere liking effect: Attitudinal influences on attributions of moral character. Konrad Bocian et al. Journal of Experimental Social Psychology, Volume 79, November 2018, Pages 9–20. https://doi.org/10.1016/j.jesp.2018.06.007

Highlights
•    The article bridges two classic areas of psychology: moral judgments and attitudes.
•    Attitudes strongly influence judgments of moral character.
•    These influences are entirely mediated by changes in liking of the judged persons.
•    Changes in mood do not play such a role.
•    Attitudinal influences might lay at the core of moral character perceptions.

Abstract: People believe that their moral judgments are well-justified and as objective as scientific facts. Still, dual-process models of judgment provide strong theoretical reasons to expect that in reality moral judgments are substantially influenced by highly subjective factors such as attitudes. In four experiments (N = 645) we provide evidence that similarity-dissimilarity of beliefs, mere exposure, and facial mimicry influence judgments of moral character measured in various ways. These influences are mediated by changes in liking of the judged persons, suggesting that attitudinal influences lay at the core of moral character perceptions. Changes in mood do not play such a role. This is the first line of studies showing that attitudes influence moral judgments in addition to frequently studied discrete emotions. It is also the first research evidencing the affective influences on judgments of moral character.
