Quantitative historical analysis uncovers a single dimension of complexity that structures global variation in human social organization. Peter Turchin et al. Proceedings of the National Academy of Sciences, doi: 10.1073/pnas.1708800115
Significance: Do human societies from around the world exhibit similarities in the way that they are structured and show commonalities in the ways that they have evolved? To address these long-standing questions, we constructed a database of historical and archaeological information from 30 regions around the world over the last 10,000 years. Our analyses revealed that characteristics, such as social scale, economy, features of governance, and information systems, show strong evolutionary relationships with each other and that complexity of a society across different world regions can be meaningfully measured using a single principal component of variation. Our findings highlight the power of the sciences and humanities working together to rigorously test hypotheses about general rules that may have shaped human history.
Abstract: Do human societies from around the world exhibit similarities in the way that they are structured, and show commonalities in the ways that they have evolved? These are long-standing questions that have proven difficult to answer. To test between competing hypotheses, we constructed a massive repository of historical and archaeological information known as “Seshat: Global History Databank.” We systematically coded data on 414 societies from 30 regions around the world spanning the last 10,000 years. We were able to capture information on 51 variables reflecting nine characteristics of human societies, such as social scale, economy, features of governance, and information systems. Our analyses revealed that these different characteristics show strong relationships with each other and that a single principal component captures around three-quarters of the observed variation. Furthermore, we found that different characteristics of social complexity are highly predictable across different world regions. These results suggest that key aspects of social organization are functionally related and do indeed coevolve in predictable ways. Our findings highlight the power of the sciences and humanities working together to rigorously test hypotheses about general rules that may have shaped human history.

Regional ambient temperature is associated with human personality
Regional ambient temperature is associated with human personality. Wenqi Wei, et al. Nature Human Behaviour 1, 890–895 (2017). doi:10.1038/s41562-017-0240-0
Abstract: Human personality traits differ across geographical regions1,2,3,4,5. However, it remains unclear what generates these geographical personality differences. Because humans constantly experience and react to ambient temperature, we propose that temperature is a crucial environmental factor that is associated with individuals’ habitual behavioural patterns and, therefore, with fundamental dimensions of personality. To test the relationship between ambient temperature and personality, we conducted two large-scale studies in two geographically large yet culturally distinct countries: China and the United States. Using data from 59 Chinese cities (N = 5,587), multilevel analyses and machine learning analyses revealed that compared with individuals who grew up in regions with less clement temperatures, individuals who grew up in regions with more clement temperatures (that is, closer to 22 °C) scored higher on personality factors related to socialization and stability (agreeableness, conscientiousness, and emotional stability) and personal growth and plasticity (extraversion and openness to experience). These relationships between temperature clemency and personality factors were replicated in a larger dataset of 12,499 ZIP-code level locations (the lowest geographical level feasible) in the United States (N = 1,660,638). Taken together, our findings provide a perspective on how and why personalities vary across geographical regions beyond past theories (subsistence style theory, selective migration theory and pathogen prevalence theory). As climate change continues across the world, we may also observe concomitant changes in human personality.

Parents and Children Who Are Estranged in Adulthood: A Review and Discussion of the Literature + NYTimes article about this
Blake, L. (2017), Parents and Children Who Are Estranged in Adulthood: A Review and Discussion of the Literature. J Fam Theory Rev, 9: 521–536. doi:10.1111/jftr.12216
Abstract: This review article examines what is known about estrangement between parents and adult children in terms of definition, prevalence, causes, and consequences. Estrangement has been defined and conceptualized in different ways, although most definitions have focused on the negative quality of the relationship and the voluntarily or intentional decision of at least one family member to initiate and maintain distance. A diverse range of factors that are often interlinked has been found to contribute to estrangement. The consequences of estrangement from a parent or child include experiencing reduced levels of psychological well-being, feelings of loss, and experiences and/or perceptions of stigma. The estrangement literature has the potential to reveal variation in the quality of parent–child relationships in adulthood so that family scholars can move beyond our assumptions and understand family relationships as they are, rather than how they could or should be.

Debunking Myths About Estrangement. By CATHERINE SAINT LOUIS.
New research challenges the deeply held notion that family relationships can’t be dissolved and suggests that estrangement is not all that uncommon.

It’s the classic image of the holidays: Parents, siblings and their children gather around the family table to feast and catch up on one another’s lives. But it doesn’t always work that way.
After years of discontent, some adults choose to stop talking to their parents or returning home for family gatherings, and parents may disapprove of a child so intensely that he or she is no longer welcome home.
In the past five years, a clearer picture of estrangement has been emerging as more researchers have turned their attention to this kind of family rupture. Their findings challenge the deeply held notion that family relationships can’t be dissolved and suggest that estrangement is not all that uncommon.
Broadly speaking, estrangement is defined as one or more relatives intentionally choosing to end contact because of an ongoing negative relationship. (Relatives who go long stretches without a phone call because of external circumstances like a military deployment or incarceration don’t fit the bill.)
“To the extent you are actively trying to distance yourself and maintain that distance, that makes you estranged,” said Kristina Scharp, an assistant professor of communication studies at Utah State University in Logan.
Last month, Lucy Blake, a lecturer at Edge Hill University in England, published a systematic review of 51 articles about estrangement in the Journal of Family Theory & Review. This body of literature, Dr. Blake wrote, gives family scholars an opportunity to “understand family relationships as they are, rather than how they could or should be.”
Estrangement is widely misunderstood, but as more and more people share their experiences publicly, some misconceptions are being overturned. Assuming that every relationship between a parent and child will last a lifetime is as simplistic as assuming every couple will never split up.
Myth: Estrangement Happens Suddenly
It’s usually a long, drawn-out process rather than a single blowout. A parent and child’s relationship erodes over time, not overnight.
Kylie Agllias, a social worker in Australia who wrote a 2016 book called “Family Estrangement,” has found that estrangement “occurs across years and decades. All the hurt and betrayals, all the things that accumulate, undermine a person’s sense of trust.”
For a study published in June, Dr. Scharp spoke to 52 adult children and found they distanced themselves from their parents in various ways over time.
Some adult children, for example, moved away. Others no longer made an effort to fulfill expectations of the daughter-son role, such as a 48-year-old woman who, after 33 years with no contact with her father, declined to visit him in the hospital or to attend his funeral.
Still others chose to limit conversations with a family member to superficial small talk or reduce the amount of contact. One 21-year-old man described how he called and texted his mother, but not his father, after leaving for college. “They still live together so obviously he noticed and that bothered him,” he said.
Estrangement is a “continual process,” Dr. Scharp said. “In our culture, there’s a ton of guilt around not forgiving your family,” she explained. So “achieving distance is hard, but maintaining distance is harder.”
A complete rupture can be years in the making. It’s been three years since Nikolaus Maack, 47, has had contact with most of his family. But he started distancing himself from his parents and siblings a decade before. “I was staying away,” said Mr. Maack, a civil servant in Ottawa. His father’s temper had always kept him on edge, he said, and he felt that holiday meals were particularly uncomfortable and demeaning. Eventually, Mr. Maack stopped attending Christmas festivities altogether.
Reached by email, Mr. Maack’s father declined to be interviewed but insulted Mr. Maack and said he no longer considered him a son.
Myth: Estrangement Is Rare
In 2014, 8 percent of roughly 2,000 British adults said that they had cut off a family member, which translates to more than five million people, according to a nationally representative survey commissioned by Stand Alone, a charity that supports estranged people.
And 19 percent of respondents reported that another relative or they themselves were no longer in contact with family.
Myth: There’s a Clear Reason People Become Estranged
Multiple factors appear to come into play. In a 2015 study, Dr. Agllias interviewed 25 Australian parents, each of whom had been cut off by at least one child. The reasons for the rupture fell into three main categories. In some cases, the son or daughter chose between the parent and someone or something else, such as a partner. In others, the adult child was punishing the parent for “perceived wrongdoing” or a difference in values. Most parents also flagged additional ongoing stressors like domestic violence, divorce and failing health.
A woman once insisted to Dr. Agllias that she had not spoken to her son and his wife in seven years because she asked her daughter-in-law to bring a specific dessert to a family gathering, and the daughter-in-law had deliberately brought the same one she had baked. The mother-in-law saw it as “a symbol of total disrespect,” Dr. Agllias said, yet she revealed other factors that had undermined their relationship, including that she felt her son’s wife sometimes kept the grandchildren from her and didn’t properly take care of her son. The dessert, Dr. Agllias said, became a symbol of the “cumulative disrespect” she felt.
Myth: Estrangement Happens on a Whim
In a study published in the journal Australian Social Work, 26 adults reported being estranged from parents for three main reasons: abuse (everything from belittling to physical or sexual abuse), betrayal (keeping secrets or sabotaging them) and poor parenting (being overly critical, shaming children or making them scapegoats). The three were not mutually exclusive, and often overlapped, said Dr. Agllias, a lecturer at the University of Newcastle in Australia.
Most of the participants said that their estrangements followed childhoods in which they had already had poor connections with parents who were physically or emotionally unavailable.
For instance, Mr. Maack resented that he was routinely left in charge of his two younger siblings, so much so that he decided never to have children of his own.
After years of growing apart, the final straw was his wedding day.
In 2014, he and his longtime girlfriend decided to marry at City Hall for practical reasons: They realized she wouldn’t be able to inherit his pension, otherwise. He didn’t invite his family, in part because it was an informal gathering. But also because a brother had recently married in a traditional ceremony, during which his father had backed out of giving his speech. He worried that his father might do something similarly disruptive. He did not want to invite him and said he didn’t think anyone else would come without him.
“I agonized over inviting them or not, for a long time,” he said, “but in the end, decided, ‘I can’t have them there.’”
His family found out he was married through Facebook. One brother told him he was hurt he wasn’t even told. And his sister and father made it clear they would no longer talk to him, according to Mr. Maack and his wife. Two other relatives confirmed their account.
These days, one brother still talks to Mr. Maack, mostly through Facebook messenger, but they don’t talk about the others.

Distinguishing Polemic From Commentary in Science: Some Guidelines Illustrated With the Case of Sage and Burgio (2017)
Grimes, D. R. and Bishop, D. V. M. (2017), Distinguishing Polemic From Commentary in Science: Some Guidelines Illustrated With the Case of Sage and Burgio (2017). Child Dev. doi:10.1111/cdev.13013
Abstract: Exposure to nonionizing radiation used in wireless communication remains a contentious topic in the public mind—while the overwhelming scientific evidence to date suggests that microwave and radio frequencies used in modern communications are safe, public apprehension remains considerable. A recent article in Child Development has caused concern by alleging a causative connection between nonionizing radiation and a host of conditions, including autism and cancer. This commentary outlines why these claims are devoid of merit, and why they should not have been given a scientific veneer of legitimacy. The commentary also outlines some hallmarks of potentially dubious science, with the hope that authors, reviewers, and editors might be better able to avoid suspect scientific claims.

Watching Without Seeing: Determinants and Mechanisms of Inattentional Blindnes
Watching Without Seeing: Determinants and Mechanisms of Inattentional Blindness / Ich sehe was, was du nicht siehst: Determinanten und Mechanismen von Inattentional Blindness. Carina Kreitz. Zeitschrift für Sportpsychologie (2017), 24, pp. 120-127. https://doi.org/10.1026/1612-5010/a000203
Abstract: We sometimes fail to consciously notice stimuli right in front of our eyes if those stimuli occur unexpectedly and our attention is diverted by another task. This phenomenon has been termed inattentional blindness and can have fatal consequences in daily-life situations as well as a severe impact on sports performance. In accordance with previous research, my findings indicate that a multitude of situational factors, including features of the unexpected object and characteristics of the context, influence the probability of inattentional blindness. By contrast, individual differences in personality and cognition do not seem to further differentiate the probability of inattentional blindness beyond situational aspects (or at least not reliably or substantially). That is, while there is a fixed probability for all observers to notice an unexpected object in a specific situation (deterministic aspect of inattentional blindness), we cannot predict who exactly will belong to the group of noticers (stochastic aspect).

The Economist On Sexual Harassment, Nov 2017
In The Economist, Friday November 17th 2017:
| Sexual harassment: Changing patterns |
| A plethora of recent examples, from Hollywood and elsewhere, have demonstrated the pervasive nature of sexual harassment towards women. A new survey shows that the range of views on what constitutes harassment is vast, diverging by age, sex and nationality. But in general, younger respondents are more likely than their older peers to think that certain types of behaviour crossed the line, writes our data team |
