Default neglect in attempts at social influence. Julian J. Zlatev et al. Proceedings of the National Academy of Sciences, vol. 114 no. 52, pp 13643–13648, doi: 10.1073/pnas.1712757114

Significance: While a great deal is known about how people respond to influence tactics that are used on them, almost nothing is known about whether people understand these tactics and strategically use them to influence others. We examine whether people are successful at using the default effect, a widely studied bias with special policy relevance, to influence others’ choices. Overall, we find that managers, law/business/medical students, and US adults often fail to understand and/or use defaults, with some interesting exceptions. These findings suggest that the scope for improving social welfare via behavioral policy interventions is vast.

Abstract: Current theories suggest that people understand how to exploit common biases to influence others. However, these predictions have received little empirical attention. We consider a widely studied bias with special policy relevance: the default effect, which is the tendency to choose whichever option is the status quo. We asked participants (including managers, law/business/medical students, and US adults) to nudge others toward selecting a target option by choosing whether to present that target option as the default. In contrast to theoretical predictions, we find that people often fail to understand and/or use defaults to influence others, i.e., they show “default neglect.” First, in one-shot default-setting games, we find that only 50.8% of participants set the target option as the default across 11 samples (n = 2,844), consistent with people not systematically using defaults at all. Second, when participants have multiple opportunities for experience and feedback, they still do not systematically use defaults. Third, we investigate beliefs related to the default effect. People seem to anticipate some mechanisms that drive default effects, yet most people do not believe in the default effect on average, even in cases where they do use defaults. We discuss implications of default neglect for decision making, social influence, and evidence-based policy.

Seven myths of memory

Seven myths of memory. Nicola S. Clayton, , Clive Wilkins. Behavioural Processes, https://doi.org/10.1016/j.beproc.2017.12.018

Highlights
•    Episodic memories are not accurate objective reflections of what happened, nor are they a permanent record of the past.
•    We don’t remember the scenes we actually saw, nor do we make a series of one-off snap shots of what happened.
•    Although we travel backwards in the mind’s eye to relive the past we do not reverse time mentally. We jump back to a specific point in time and then play the memory forwards again.
•    Memory is only used to recall the past for it evolved to anticipate and imagine future scenarios. In thinking about the future, however, we make a fundamental mistake, namely that we think the future will be more like the past and the present than it will ever really be. This is because we overvalue the self in the here and now.

Abstract: In this paper we highlight seven myths about memory, which centre around the fact that memories, as we experience them, are not only about the past, they are also prospective. Although episodic memory provides the template for future scenarios, it can be reassessed each time it is recalled, and in part is dependent on the sequence in which events unfold. We explore seven myths about memory, and the relationship between memory and experience. We refer to ‘The Moustachio Quartet’, a series of novels, which highlight themes and ideas relevant to our argument, and ‘The Creatures in the Night’, a picture book of paintings that explore the passage of time. We integrate evidence from science and the arts to explore the subjective nature of memory and mental time travel, arguing that our capacity to juggle multiple perspectives evolved for the act of prospection, as an aid to move time forward to the advantage of our species by imagining future scenarios.

Disadvantageous inequity-aversion (“envy”) is stronger under time pressure

Exploring the Role of Deliberation Time in Non-Selfish Behavior: the Double Response Method. Michał Krawczyk, , Marta Sylwestrzak. Journal of Behavioral and Experimental Economics, https://doi.org/10.1016/j.socec.2017.12.004

Highlights
•    We develop and apply a novel method for eliciting laboratory subjects’ preference
•    The method incentivizes providing a quick, intuitive response and a more thought-out response
•    We apply the method to the Charness & Rabin's choices measuring social preference
•    We find that disadvantageous inequity-aversion (“envy”) is stronger under time pressure

Abstract: In this paper, we explore the Double Response research method, in which, in each decision task, subjects supply one quick choice and one additional choice after a longer deliberation time. Assuming a simple dual-process framework, with the two modes of judgment running parallel to each other providing the decision-maker with their final estimates of the utility difference between the options, this method incentivizes the decision-maker to indicate which option they prefer in System 1 and which option is preferred in System 2. We apply the method to a series of simple decision tasks aimed at eliciting subjects’ social preferences (as in Charness and Rabin, 2002). We observe that time pressure leads to a negative attitude towards the earnings of other participants when they are higher than those of the decision-maker. In other words, deliberation decisions are typically updated towards those corresponding with lower aversion to disadvantageous inequality (“envy”).

Keywords: Response time; Design of laboratory experiments; Other-regarding preference; Inequality aversion

---
The second contribution of the present study lies in the novel findings in the specific area of other-regarding behavior. As far as we know, the observation that a disadvantageous inequality aversion (as opposed to other motives to lower the payoff of another subject) is strengthened under time pressure is novel. Generally speaking, it contradicts the Social Heuristics Hypothesis of Rand and colleagues. One plausible explanation for this phenomenon is that the subject's own payoff initially appears to be low when compared to the high payoff the other subject is enjoying. With more deliberation time, subjects tend to find that, in fact, there is no reason not to let the other person earn a bit more money. This effect provides an alternative explanation to the findings of higher rejection rates in the Ultimatum Game played under time pressure, often understood in terms of emotion-driven revenge. Additionally, intuitive disadvantageous inequality aversion allows explaining ―hot-headed‖ behavior in situations in which no evil intentions can be attributed to the other party. For example, many drivers seem to change lanes much too often in heavy traffic. By doing so, they generally diminish their average driving speed and increase the risk of causing a collision without receiving any substantial benefit in terms of time saved. This is particularly puzzling in view of laboratory findings, such as a reluctance to exchange lottery tickets (Bar-Hillel et al., 1996), suggesting a strong status-quo bias. It could be that such drivers‘ behavior may be explained in view of its timing – typically one has to decide very quickly whether or not to change to another lane that temporarily seems to allow a quicker ride. If this time pressure puts drivers in a mode in which they find it hard to accept that somebody else is making more progress, it is likely to result in excessive lane switching.

The cyclic sexual & reproductive behavior of human populations is mostly driven by culture & this interest in sex is associated with specific emotions, characteristic of major cultural & religious celebrations

Human Sexual Cycles are Driven by Culture and Match Collective Moods. Ian B. Wood, Pedro L. Varela, Johan Bollen, Luis M. Rocha & Joana Gonçalves-Sá. Scientific Reports 7, Article number: 17973 (2017). doi:10.1038/s41598-017-18262-5

Abstract: Human reproduction does not happen uniformly throughout the year and what drives human sexual cycles is a long-standing question. The literature is mixed with respect to whether biological or cultural factors best explain these cycles. The biological hypothesis proposes that human reproductive cycles are an adaptation to the seasonal (hemisphere-dependent) cycles, while the cultural hypothesis proposes that conception dates vary mostly due to cultural factors, such as holidays. However, for many countries, common records used to investigate these hypotheses are incomplete or unavailable, biasing existing analysis towards Northern Hemisphere Christian countries. Here we show that interest in sex peaks sharply online during major cultural and religious celebrations, regardless of hemisphere location. This online interest, when shifted by nine months, corresponds to documented human births, even after adjusting for numerous factors such as language and amount of free time due to holidays. We further show that mood, measured independently on Twitter, contains distinct collective emotions associated with those cultural celebrations. Our results provide converging evidence that the cyclic sexual and reproductive behavior of human populations is mostly driven by culture and that this interest in sex is associated with specific emotions, characteristic of major cultural and religious celebrations.

China Bullies Mr. Moon. Beijing wants South Korea to remove its missile defenses without helping with North Korea

China Bullies Mr. Moon.  By The Editorial Board
Beijing wants South Korea to remove its missile defenses.
The Wall Street Journal, Dec. 22, 2017 6:10 p.m. ET
https://www.wsj.com/articles/china-bullies-mr-moon-1513984245

South Korean President Moon Jae-in is learning that appeasement is a dangerous game. After he bowed last month to Beijing’s strong-arming and limited deployment of a U.S.-built missile-defense system, relations between the two countries seemed to be back on track. But China has now resumed its pressure tactics.

Mr. Moon’s predecessor began to deploy the Terminal High Altitude Area Defense in March to defend against North Korean missile attack. Beijing objected that the Thaad radar can peer into its airspace and demanded it be dismantled. China stopped its citizens from visiting the country on package tours and harassed South Korean companies. Those unofficial sanctions trimmed almost $7 billion from the Korean economy this year.

After his election in May, Mr. Moon suspended the Thaad deployment, officially for an environmental review. That angered Washington, which had paid for the system. The new President eventually agreed to deploy the launchers that were already imported.

But the delay showed Beijing it could intimidate Mr. Moon, and it pressed him harder. On Oct. 31 Mr. Moon again bowed to China, pledging not to deploy more Thaad units, join a larger U.S. missile-defense network or form a defense alliance with Japan. That compromised South Korea’s security, since the Thaad units deployed so far cover only part of the country and could be overwhelmed by North Korean short-range missiles.

Yet China still wasn’t satisfied, and the reconciliation started to unravel when Mr. Moon visited Beijing last week. He was met by low-level officials at the airport, a clear snub. Then security guards beat journalists traveling with him, one of whom was hospitalized. The two sides failed to issue a joint statement.

This week China raised tensions again by sending three fighter jets and two bombers into South Korea’s air defense identification zone, causing its military to scramble jets to intercept them. Chinese fishing boats, which double as a maritime militia, charged South Korean coast guard vessels, forcing them to fire warning shots. The flow of Chinese tourist groups to South Korea has again dried up.

Beijing wants to drive a wedge between Washington and Seoul on the Thaad deployment, and it is pressing the issue. China wants Mr. Moon to remove Thaad entirely and support its proposed deal on North Korea’s nuclear program. The “freeze for a freeze” plan would have U.S. and South Korean forces suspend their joint exercises in return for the North halting its nuclear testing.

That would cripple the U.S.-South Korea alliance, which is Beijing’s goal. Without regular exercises, the two countries’ ability to deter provocations by the North would wither. And Pyongyang could continue its weapons development in secret.

Mr. Moon’s attempts to appease Beijing have only led to fresh demands. He can restore his credibility by deploying more Thaad radars and launchers that South Korea badly needs. If China doesn’t like Thaad, it can help eliminate the threat from North Korea.

Higher social class consistently related to lower levels of wise reasoning across different levels of analysis, including regional and individual differences

Social class and wise reasoning about interpersonal conflicts across regions, persons and situations. Justin P. Brienza, Igor Grossmann. Proceedings of the Royal Society B, DOI: 10.1098/rspb.2017.1870

Abstract: We propose that class is inversely related to a propensity for using wise reasoning (recognizing limits of their knowledge, consider world in flux and change, acknowledges and integrate different perspectives) in interpersonal situations, contrary to established class advantage in abstract cognition. Two studies—an online survey from regions differing in economic affluence (n = 2 145) and a representative in-lab study with stratified sampling of adults from working and middle-class backgrounds (n = 299)—tested this proposition, indicating that higher social class consistently related to lower levels of wise reasoning across different levels of analysis, including regional and individual differences, and subjective construal of specific situations. The results held across personal and standardized hypothetical situations, across self-reported and observed wise reasoning, and when controlling for fluid and crystallized cognitive abilities. Consistent with an ecological framework, class differences in wise reasoning were specific to interpersonal (versus societal) conflicts. These findings suggest that higher social class weighs individuals down by providing the ecological constraints that undermine wise reasoning about interpersonal affairs.

Correlation between gut microbiota and personality in adults: a cross-sectional study

Correlation between gut microbiota and personality in adults: a cross-sectional study. Han-Na Kim et al. Brain, Behavior, and Immunity, https://doi.org/10.1016/j.bbi.2017.12.012

Highlights
•    Personality traits were correlated with gut microbiota composition.
•    Gammaproteobacteria was increased in high neuroticism group.
•    Low conscientiousness group showed increased abundance of Proteobacteria.
•    The low conscientiousness group showed decreased abundance of Lachnospiraceae.

Abstract: Personality affects fundamental behavior patterns and has been related with health outcomes and mental disorders. Recent evidence has emerged supporting a relationship between the microbiota and behavior, referred to as brain-gut relationships. Here, we first report correlations between personality traits and gut microbiota. This research was performed using the Revised NEO Personality Inventory and the sequencing data of the 16S rRNA gene in 672 adults. The diversity and the composition of the human gut microbiota exhibited significant difference when stratified by personality traits. We found that personality traits were significantly correlated with diversity of gut microbiota, while their differences were extremely subtle. High neuroticism and low conscientiousness groups were correlated with high abundance of Gammaproteobacteria and Proteobacteria, respectively when covariates, including age, sex, BMI and nutrient intake, were controlled. Additionally, high conscientiousness group also showed increased abundance of some universal butyrate-producing bacteria including Lachnospiraceae. This study was of observational and cross-sectional design and our findings must be further validated through metagenomic or metatranscriptomic methodologies, or metabolomics-based analyses. Our findings will contribute to elucidating potential links between the gut microbiota and personality, and provide useful insights toward developing and testing personality- and microbiota-based interventions for promoting health.

Political attitudes display interspousal correlations that are among the strongest of all social and biometric traits

The Politics of Mate Choice. John R. Alford et al. The Journal of Politics, Vol. 73, No. 2, April 2011, Pp. 362–379, doi:10.1017/S0022381611000016

Abstract: Recent research has found a surprising degree of homogeneity in the personal political communication network of individuals  but  this  work  has  focused  largely  on  the  tendency  to  sort  into  likeminded  social,  workplace,  and residential political contexts. We extend this line of research into one of the most fundamental and consequential of political interactions—that between sexual mates. Using data on thousands of spouse pairs in the United States, we investigate  the  degree  of  concordance  among  mates  on  a  variety  of  traits.  Our  findings  show  that  physical and personality traits display only weakly positive and frequently insignificant correlations across spouses. Conversely, political attitudes display interspousal correlations that are among the strongest of all social and biometric traits. Further, it appears the political similarity of spouses derives in part from initial mate choice rather than persuasion and accommodation over the life of the relationship.

Quantitative historical analysis uncovers a single dimension of complexity that structures global variation in human social organization

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.

The New York Times, Dec 20, 2017

photos ommited

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.

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).

Keywords: attention, inattentional blindness, failures of awareness
