Distrust of nonreligious individuals is almost completely erased by knowledge that they are following a restricted monogamous lifestyle; thus, reproductive strategies often underlie apparently sacred concerns

Is Nothing Sacred? Religion, Sex, and Reproductive Strategies. Jordan W. Moon et al. Current Directions in Psychological Science, April 29, 2019. https://doi.org/10.1177/0963721419838242

Abstract: Religion has often been conceptualized as a collection of beliefs, practices, and proscriptions that lift people’s thoughts and behaviors out of the metaphorical gutter of sex and selfishness toward lives full of meaning, contemplation, and community service. But religious beliefs and behaviors may serve selfish, sexual motivations in ways that are not always obvious or consciously intended. We review two lines of research illustrating nonobvious links between the mundane and the religious. First, contrary to long-held assumptions that religious upbringing causes sexually restrictive attitudes and behaviors, several large data sets now suggest a reverse causal arrow—people’s preferred mating strategies determining their attraction toward, or repulsion from, religion. Second, other recent findings suggest that distrust of nonreligious individuals is almost completely erased by knowledge that they are following a restricted monogamous lifestyle. Thus, reproductive strategies often underlie apparently sacred concerns. We close with a consideration of ways in which reproductive interests might underlie a broad range of benefits associated with religious affiliation.

Thought-Control Failure: Sensory Mechanisms and Individual Differences

Measuring Thought-Control Failure: Sensory Mechanisms and Individual Differences. Eugene L. Kwok et al. Psychological Science, April 22, 2019. https://doi.org/10.1177/0956797619837204

Abstract: The ability to control one’s thoughts is crucial for attention, focus, ideation, and mental well-being. Although there is a long history of research into thought control, the inherent subjectivity of thoughts has made objective examination, and thus mechanistic understanding, difficult. Here, we report a novel method to objectively investigate thought-control success and failure by measuring the sensory strength of visual thoughts using binocular rivalry, a perceptual illusion. Across five experiments (N = 67), we found that thought-control failure may occur because of the involuntary and antithetical formation of nonreportable sensory representations during attempts at thought suppression but not during thought substitution. Notably, thought control was worse in individuals with high levels of anxiety and schizotypy but more successful in mindful individuals. Overall, our study offers insight into the underlying mechanisms of thought control and suggests that individual differences play an important role in the ability to control thoughts.

---
The ability to control our own thoughts, is an important mental capacity and is important for attention, focus, future planning and ideation [1-4]. Given that up to 80% of the general population experience some form of unwanted intrusive thoughts [5], the ability to control thoughts is also an important determinant of mental wellbeing [6]. Indeed, failure to control thoughts has been linked to various mental disorders including anxiety[7, 8], obsessive-compulsive disorder (OCD) [9, 10] and schizophrenia [11, 12].

Since the work of Freud, the idea of voluntarily repressing a thought, thought suppression, has become an active phrase in the general populace and has attracted muchattention, despite the lack of any clear objective methodology to investigate the phenomenon. Attempting to control thoughts by direct thought suppression (not thinking about a given thought) is often difficult and subjective reports suggest suppression mostly fails [6]. Instead of directly eliminating thoughts from the mind, reports suggest suppression paradoxically leads to heightened preoccupations with these thoughts [13]. For example, individuals instructed to suppress the thought of a white bear are often unable to do so and report intrusions of the thought inadvertently arising a short time later [14]. Research into thought suppression failure (e.g. [15-20]) and its consequences have been studied in a wide variety of domains including organisational behaviour [21], smoking addiction [22], immune function [23] and psychopathology [24-27]. However, largely due to the inherent private subjectivity of thought suppression, its existence as a possible process, dynamics, where and why such suppression failures originate, remains largely unknown. While thought suppression is the most commonly studied thought control strategy, other forms of thought control have been examined and seem to be more effective. For example, thought substitution, in which a suppressed thought is instead replaced by a substitute thought, has shown evidence for reduced thought intrusion frequency and thought control failure [6, 14, 28]. More recently, mindfulness has shown evidence as an effective form of mental control [29].

While these forms of thought control seem more effective than direct thought suppression, without a mechanistic understanding of these processes, research into why one method might work over another, and indeed if there are potentially more effective methods remains limited.

Wegner [13] first attributed the inability to control thoughts using thought suppression to the interaction between two practical, but simultaneously conflicting, mental processes. The first involves a conscious process that attempts to achieve a state of mind free from the to-be-suppressed thought. The second is an unconscious monitoring process that checks for unwanted instances of the to-be-suppressed thought. Wegner proposed thoughts unwillingly enter consciousness due to the ironic opposition between these two processes, ultimately leading to thought control failure. Neuroimaging evidence has generally supported this view [30-32]. However, while mechanisms have been proposed, the empirical investigation and objective measurement of thought control has been limited.

The inherent subjectivity of thoughts has further made the objective examination of thought control difficult. For the most part, previous research has used subjective self-reports to examine thought control ( e.g. [14, 28, 33, 34]). While self-report measures have provided valuable insight into the examination of thought control, these measures may be prone to bias, experimenter demand or social desirability effects [35], and thus make it difficult to examine the underlying mechanisms.

To overcome this subjectivity and to shed light on the underlying mechanisms of thought control and its failure we devised a novel method to objectively study the control of visual thoughts using the illusion binocular rivalry. Binocular rivalry is a visual illusion that arises when two different images are presented one to each eye, inducing bistable perceptual alternations between the two images [36]. Binocular rivalry has been used to objectively measure the sensory strength of mental images [37-40] and prior perceptual stimuli [37, 39, 41]. Here we devised a novel method to utilise a brief binocular rivalry presentation to objectively assess visual representations that might emerge during attempts at thought control.

In each trial, we instructed participants to either imagine, suppress or substitute the thought of a red or green coloured object, before being presented with a brief red-green binocular rivalry stimulus. Any priming for imagined, suppressed or substituted thoughts could then be calculated to provide an objective measure of the sensory strength of these visual thought representations. To probe subjective metacognition of thought control, we instructed participants to report when thought control failed and compared these subjective reports to their level of rivalry priming. Lastly, a Thought Control Index was devised to investigate the relationship between thought control and four psychological traits: anxiety, obsessive-compulsive tendencies, schizotypy and mindfulness.

Results showed suppressed thoughts led to binocular rivalry priming significantly above chance (50%) and almost as strong as priming for intentionally imagined thoughts, indicating a failure to control the sensory trace of thoughts using thought suppression. Surprisingly, priming for trials reported as successfully suppressed was still significantly above chance, suggesting the possibility of emergent non-conscious sensory representations during attempts at thought control. Thought substitution was more, although not completely effective, in controlling the sensory trace of visual thoughts. Individuals with high trait mindfulness exhibited greater levels of thought control, whilethose with high anxiety or schizotypy traits exhibited lower levels of thought control. Interestingly, there was no relationship with obsessive-compulsive tendencies. Our data suggest that thought control failure is linked to the formation of sensory representations during attempts at thought control.

In Indonesia: Cognitive dissonance in women who are addicted to pornography

In Indonesia: Cognitive dissonance in women who are addicted to pornography. Rendy Alfiannoor Achmad, Ayunia Firdayati. Jurnal Ecopsy, Vol 6, No 1 (2019). http://dx.doi.org/10.20527/ecopsy.v6i1.6028

Abstract: Based on a Google Trends survey, Indonesia is ranked as the world's top 10 consuming pornographic material for the types of keywords that are related to sex, and an average of 20% of all categories are conducted by student-aged adolescents. This study aims to describe how cognitive dissonance is experienced by women who are addicted to pornography. The method used in this study is a qualitative method with a case study approach. Data was collected by observation and interview, the subject of the study was a woman who had been exposed to pornography since sitting in elementary school. The results of the study explained that the source of the occurrence of cognitive dissonance of the subject was due to a discrepancy between the subject's beliefs and assessment of the new environment towards the subject's habit of watching pornographic videos. Cognitive dissonance experienced by women who are addicted to pornography is the emergence of feelings of anxiety, feelings of guilt, sin, feelings of fear are considered 'disgusting', and also feel their behavior is only a waste of time.

Polygamous marriages: Women assigned greater sentence durations & perceived the transgressions toward the institution of marriage as more severe than men; the presence of children increased the troublesomeness of the polygamy

Widman, D. R., Philip, M. M., & Geher, G. (2018). Punishment of hypothetical polygamous marriages. Evolutionary Behavioral Sciences, http://dx.doi.org/10.1037/ebs0000155

Abstract: Parental investment theory suggests that differential reproductive investment has led the sexes to different mating strategies. In humans, men have the lesser investment and therefore tend to desire greater numbers of mates relative to women. One result of this could be that men would be more tolerant of polygamous marriages. The present study examined this hypothesis. Participants read 4 hypothetical vignettes describing individuals who were convicted of polygamy. The vignettes varied in the sex of the perpetrator and whether the marriage resulted in children or not. Participants were asked to suggest a sentence duration and to assess the severity of that sentence, as well as the severity of the transgression to the spouses, the institution of marriage, and in general. Participants also completed several scales relevant to reproduction. The results indicated that women assigned greater sentence durations and perceived the transgressions toward the institution of marriage and in general as more severe than men. In addition, the presence of children increased the troublesomeness of the polygamy. Finally, life history and the troublesomeness of the polygamy were positively correlated, but only in men. This is consistent with the male strategy of dads with slow life histories and cads with fast life histories. The lack of correlation in women may be an indication of smaller variation in reproduction relative to men, regardless of life history.

Individuals who claim knowledge/expertise where they have little experience or skill exhibit high levels of overconfidence, believe they work hard, persevere at tasks, & are popular

Bullshitters. Who Are They and What Do We Known about Their Lives? John Jerrim, Phil Parke, rNikki Shure. IZA DP No. 12282. http://ftp.iza.org/dp12282.pdf

‘Bullshitters’ are individuals who claim knowledge or expertise in an area where they actually have little experience or skill. Despite this being a well-known and widespread social phenomenon, relatively few large-scale empirical studies have been conducted into this issue. This paper attempts to fill this gap in the literature by examining teenagers’ propensity to claim expertise in three mathematics constructs that do not really exist. Using Programme for International Student Assessment (PISA) data from nine Anglophone countries and over 40,000 young people, we find substantial differences in young people’s tendency to bullshit across countries, genders and socio-economic groups. Bullshitters are also found to exhibit high levels of overconfidence and believe they work hard, persevere at tasks, and are popular amongst their peers. Together this provides important new insight into who bullshitters are and the type of survey responses that they provide.

Coupled gay men did more physical activity than coupled straight men and were 1.62x more likely to be active, 1.67x more likely to be high active, 1.89x more likely to engage in muscle-strengthening activities

A Population-Based Study of Coupling and Physical Activity by Sexual Orientation for Men. Joseph S. Lightner, Katie M. Heinrich & Matthew R. Sanderson. Journal of Homosexuality, Apr 25 2019. https://doi.org/10.1080/00918369.2019.1601435

ABSTRACT> Research has suggested that men in relationships are more physically active than men who are single. This study provides a weighted analysis of physical activity by coupling status for men of different sexual orientations. Aggregated data from the United States 2013–2014 National Health Interview Survey were used to conduct multivariate logistic regression analyses. Compared to straight men (n = 29,926), gay men (n = 623) were less likely to be in a relationship (AOR 0.32, CI: 0.25–0.41). Coupled gay men did more physical activity than coupled straight men and were 1.62 (CI: 1.05–2.50) times more likely to be active, 1.67 (CI: 1.10–2.51) times more likely to be high active, 1.89 (CI: 1.24–2.89) times more likely to engage in muscle-strengthening activities, and 2.00 (CI: 1.28–3.11) times more likely to meet aerobic and muscle-strengthening recommendations. Coupling facilitates physical activity for men. However, more research is needed to help explore underlying mechanisms for differences by sexuality.

Are U.S. older adults getting lonelier? No evidence that loneliness is substantially higher among the Baby Boomers or that it has increased over the past decade

Hawkley, L. C., Wroblewski, K., Kaiser, T., Luhmann, M., & Schumm, L. P. Are U.S. older adults getting lonelier?: Age, period, and cohort differences. Psychology and Aging, accepted. https://osf.io/cu8g7

Media portrayals of a loneliness “epidemic” are premised on an increase in the proportion of people living alone and decreases in rates of civic engagement and religious affiliation over recent decades. However, loneliness is a subjective perception that does not correspond perfectly with objective social circumstances. In this study, we examine whether perceived loneliness is greater among the Baby Boomers—individuals born 1948–1965—relative to those born 1920–1947, and whether older adults have become lonelier over the past decade (2005–2016). We use data from the National Social Life, Health and Aging Project (NSHAP) and from the Health and Retirement Study (HRS) collected during 2005–16 to estimate diferences in loneliness associated with age, birth year and survey timepoint. Overall, loneliness decreases with age through the early 70s, after which it increases. We fnd no evidence that loneliness is substantially higher among the Baby Boomers or that it has increased over the past decade. Loneliness is however associated with poor health, living alone or without a spouse/partner and having fewer close family and friends, which together account for the overall increase in loneliness after age 75. Although these data do not support the idea that older adults are becoming lonelier, the actual number of lonely individuals may increase as the Baby Boomers age into their 80s and beyond. Our results suggest that attention to social factors and improving health may help to mitigate this.

Cancer-free men who consumed alcohol had a slightly lower risk of lethal prostate cancer compared with abstainers; among men with prostate cancer, red wine was associated with a lower risk of progression to lethal disease

Alcohol Intake and Risk of Lethal Prostate Cancer in the Health Professionals Follow-Up Study. Mary K. Downer et al. DOI: 10.1200/JCO.18.02462 Journal of Clinical Oncology, April 26, 2019

Abstract
PURPOSE: It is unknown whether alcohol intake is associated with the risk of lethal (metastatic or fatal) prostate cancer. We examine (1) whether alcohol intake among men at risk of prostate cancer is associated with diagnosis of lethal prostate cancer and (2) whether intake among men with nonmetastatic prostate cancer is associated with metastasis or death.

METHODS: This prospective cohort study uses the Health Professionals Follow-Up Study (1986 to 2012). Our analysis of alcohol intake among men at risk of prostate cancer included 47,568 cancer-free men. Our analysis of alcohol intake among men with prostate cancer was restricted to 5,182 men diagnosed with nonmetastatic prostate cancer during follow-up. We examine the association of total alcohol, red and white wine, beer, and liquor with lethal prostate cancer and death. Multivariate Cox proportional hazards regression estimated hazard ratios (HRs) and 95% CIs.

RESULTS: Alcohol drinkers had a lower risk of lethal prostate cancer (any v none: HR, 0.84 [95% CI, 0.71 to 0.99]) without a dose-response relationship. Total alcohol intake among patients with prostate cancer was not associated with progression to lethal prostate cancer (any v none: HR, 0.99 [95% CI, 0.57 to 1.72]), whereas moderate red wine intake was associated with a lower risk (any v none: HR, 0.50 [95% CI, 0.29 to 0.86]; P trend = .05). Compared with none, 15 to 30 g/d of total alcohol after prostate cancer diagnosis was associated with a lower risk of death (HR, 0.71 [95% CI, 0.50 to 1.00]), as was red wine (any v none: HR, 0.74 [95% CI, 0.57 to 0.97]; P trend = .007).

CONCLUSION: Cancer-free men who consumed alcohol had a slightly lower risk of lethal prostate cancer compared with abstainers. Among men with prostate cancer, red wine was associated with a lower risk of progression to lethal disease. These observed associations merit additional study but provide assurance that moderate alcohol consumption is safe for patients with prostate cancer.
