The Impact of Abnormally Shaped Vegetables on Consumers’ Risk Perception. Natascha Loebnitz and Klaus G. Grunert. Food Quality and Preference, https://doi.org/10.1016/j.foodqual.2017.08.004

Highlights
•    We examine vegetable shape abnormality on consumers’ risk perception.
•    Vegetable shape abnormality affect risk perception through food’s perceived naturalness.
•    Abnormally shaped vegetables are seen as unnatural which in turn increases risk perception.
•    Knowledge types moderate the vegetable shape – risk perception relationship.

Abstract: Genetically-modified (GM) food evokes high levels of fear and negative associations among consumers. This study predicts that people may associate naturally occurring vegetable shape-abnormalities with GM food, which increases their risk perception. With an experimental design in two studies, this research investigates the impact of abnormally-shaped vegetables on participants’ risk perceptions related to vegetable items that vary in their degree of association with GM technology. The results reveal that knowledge can moderate the vegetable shape-abnormality–risk relationship, depending on its objectivity or subjectivity.

Keywords: Abnormally-shaped vegetables; Risk perception; Knowledge types; Perceived naturalness; GM food

My comment: "Consumers perceive abnormally-shaped vegetables as more risky [...] and paradoxically, they associate natural vegetable shape-abnormalities with GM, despite having no other information available" & "increasing consumers' objective knowledge about food production does not prevent risk perceptions."

Gender equality, value violations, and prejudice toward Muslims

Gender equality, value violations, and prejudice toward Muslims. Aaron Moss et al. Group Processes & Intergroup Relations, https://doi.org/10.1177/1368430217716751

Abstract: Why are people prejudiced toward Muslims? In this research, we used a value violation framework to predict that when people believe Muslims value gender equality less than reference groups, it creates a value violation that leads to prejudice. In Study 1, people believed that Muslims value gender equality less than Christians, and the more people believed that Muslims do not value gender equality, the more they reported prejudice toward Muslims. In Study 2, we manipulated perceptions of how much Muslims value gender equality by giving people evidence that Muslims either do or do not support women’s rights. Afterward, we measured people’s prejudice toward Muslims and desire for social distance. Telling people that Muslims value gender equality reduced both prejudice and the desire for social distance. These effects occurred by increasing people’s beliefs that they share values with Muslims, highlighting the importance of values as a source of prejudice.

Do post-reproductive aged females promote maternal health? Preliminary evidence from historical populations

Do post-reproductive aged females promote maternal health? Preliminary evidence from historical populations. Alison Gemmill and Ralph Catalano. Evolution, Medicine, and Public Health, eox012, https://doi.org/10.1093/emph/eox012

Abstract
Background and Objectives: Much literature argues that natural selection conserved menopause and longevity in women because those who stopped childbearing helped bolster daughters’ fertility and reduce infant mortality among grandchildren. Whether the presence of grandmothers ever improved fitness sufficiently to affect longevity via natural selection remains controversial and difficult to test. The argument underlying the grandmother and associated alloparenting literature, however, leads us to the novel and testable prediction that the presence of older women in historical societies could have affected population health by reducing lethality associated with childbearing.

Methodology: Using historical life table data from four societies (Denmark, England and Wales, France, and Sweden), we test the hypothesis that death rates among women initiating childbearing declined when the societies in which they were embedded included unexpectedly high frequencies of older women. We use time series analysis to measure the extent to which the observed likelihood of death among women aged 20-24 differs from statistically expected values when the number of older women grows or declines.

Results: In three of the four countries examined, we find an inverse relationship between the frequency of post-reproductive females in the population and odds of mortality among females at the peak of childbearing initiation.

Conclusions and implications: Results suggest that the presence of older women in a population may enhance population health by reducing mortality among women who face high risk of maternal death, although additional research is needed to determine if this relationship is causal.

The Future of Secularism: A Biologically Informed Theory Supplemented with Cross-Cultural Evidence

The Future of Secularism: A Biologically Informed Theory Supplemented with Cross-Cultural Evidence. Lee Ellis et al. Evolutionary Psychological Science, September 2017, Volume 3, Issue 3, pp 224–242, https://doi.org/10.1007/s40806-017-0090-z

Abstract: For over a century, social scientists have predicted declines in religious beliefs and their replacement with more scientific/naturalistic outlooks, a prediction known as the secularization hypothesis. However, skepticism surrounding this hypothesis has been expressed by some researchers in recent decades. After reviewing the pertinent evidence and arguments, we examined some aspects of the secularization hypothesis from what is termed a biologically informed perspective. Based on large samples of college students in Malaysia and the USA, religiosity, religious affiliation, and parental fertility were measured using self-reports. Three religiosity indicators were factor analyzed, resulting in an index for religiosity. Results reveal that average parental fertility varied considerably according to religious groups, with Muslims being the most religious and the most fertile and Jews and Buddhists being the least. Within most religious groupings, religiosity was positively associated with parental fertility. While cross-sectional in nature, ***when our results are combined with evidence that both religiosity and fertility are substantially heritable traits, findings are consistent with view that earlier trends toward secularization (due to science education surrounding advancements in science) are currently being counter-balanced by genetic and reproductive forces. We also propose that the inverse association between intelligence and religiosity, and the inverse correlation between intelligence and fertility lead to predictions of a decline in secularism in the foreseeable future. A contra-secularization hypothesis is proposed and defended in the discussion. It states that secularism is likely to undergo a decline throughout the remainder of the twenty-first century, including Europe and other industrial societies***.

Keywords: Religions, Religiosity, Secularization, Parental fertility, Cross-cultural

My comment: Very interesting article. I believed, from a long time, that the people needs religion. A different thing is what will happen to some strands, like those in Evangelical Christianity that support creationism instead of evolutionism. Maybe these groups will diminish. Or maybe all traditional religions will suffer a decrease in influence, althouth the total sum of religions will increase in the XXI century...

High rates (40%) of smokers enrolled in smoking cessation trials lie about their abstinence

Scheuermann, T. S., Richter, K. P., Rigotti, N. A., Cummins, S. E., Harrington, K. F., Sherman, S. E., Zhu, S.-H., Tindle, H. A., Preacher, K. J., and the Consortium of Hospitals Advancing Research on Tobacco (CHART) (2017) Accuracy of self-reported smoking abstinence in clinical trials of hospital-initiated smoking interventions. Addiction, doi: 10.1111/add.13913

Abstract
Aims: To estimate the prevalence and predictors of failed biochemical verification of self-reported abstinence among participants enrolled in trials of hospital-initiated smoking cessation interventions.

Design: Comparison of characteristics between participants who verified and those who failed to verify self-reported abstinence.

Settings: Multi-site randomized clinical trials conducted between 2010 and 2014 in hospitals throughout the United States.

Participants: Recently hospitalized smokers who reported tobacco abstinence 6 months post-randomization and provided a saliva sample for verification purposes (n = 822).

Measurements: Outcomes were salivary cotinine-verified smoking abstinence at 10 and 15 ng/ml cut-points. Predictors and correlates included participant demographics and tobacco use; hospital diagnoses and treatment; and study characteristics collected via surveys and electronic medical records.

Findings: Usable samples were returned by 69.8% of the 1178 eligible trial participants who reported 7-day point prevalence abstinence. The proportion of participants verified as quit was 57.8% [95% confidence interval (CI) = 54.4, 61.2; 10 ng/ml cut-off] or 60.6% (95% CI = 57.2, 63.9; 15 ng/ml). Factors associated independently with verification at 10 ng/ml were education beyond high school education [odds ratio (OR) = 1.51; 95% CI = 1.07, 2.11], continuous abstinence since hospitalization (OR = 2.82; 95% CI = 2.02, 3.94), mailed versus in-person sample (OR = 3.20; 95% CI = 1.96, 5.21) and race. African American participants were less likely to verify abstinence than white participants (OR = 0.64; 95% CI = 0.44, 0.93). Findings were similar for verification at 15 ng/ml. Verification rates did not differ by treatment group.

Conclusions: In the United States, high rates (40%) of recently hospitalized smokers enrolled in smoking cessation trials fail biochemical verification of their self-reported abstinence.

Being similar while judging right and wrong: The effects of personal and situational similarity on moral judgements

Pascal, E. (2017), Being similar while judging right and wrong: The effects of personal and situational similarity on moral judgements. Int J Psychol. doi:10.1002/ijop.12448

Abstract: This study investigated the effects of similarity with the transgressor and the victim on the perceived immorality of the transgression. Participants read two stories describing a person that cheated on their partner and a police officer that mistreated somebody. In the first story we manipulated participants' personal similarity to the transgressor and in the second their personal similarity to the victim. In each story, participants' past situational similarity to the target character was assessed according to their previous experiences of being in the same position. Results show that ***both personal and past situational similarity to the transgressor determine less severe moral judgements, while personal and past situational similarity with the victim have the opposite effect***. We also tested several potential mediators of these effects, derived from competing theoretical accounts of the influence of similarity on perceived responsibility. Empathy emerged as mediating most of the effects of similarity on moral judgements, except those induced by past situational similarity with the victim. The foreseen probability of being in a similar situation mediated only the effects of similarity to the transgressor, and not those of similarity to the victim. ***Overall, results highlight the complex mechanisms of the influences of similarity on moral judgements***.

Religion, Repulsion, and Reaction Formation: Transforming Repellent Attractions and Repulsions

Religion, Repulsion, and Reaction Formation: Transforming Repellent Attractions and Repulsions. Dov Cohen, Emily Kim and Nathan Hudson. Journal of Personality and Social Psychology, https://www.ncbi.nlm.nih.gov/pubmed/28604017

Abstract: Protestants were more likely than non-Protestants to demonstrate phenomena consistent with the use of reaction formation. Lab experiments showed that when manipulations were designed to produce taboo attractions (to unconventional sexual practices), Protestants instead showed greater repulsion. When implicitly conditioned to produce taboo repulsions (to African Americans), Protestants instead showed greater attraction. Supportive evidence from other studies came from clinicians’ judgments, defense mechanism inventories, and a survey of respondent attitudes. Other work showed that Protestants who diminished and displaced threatening affect were more likely to sublimate this affect into creative activities; the present work showed that Protestants who do not or cannot diminish or displace such threatening affect instead reverse it. Traditional individual difference variables showed little ability to predict reaction formation, suggesting that the observed processes go beyond what we normally study when we talk about self-control.

Unintended Effects of Providing Risk Information About Drinking and Driving

The Unintended Effects of Providing Risk Information About Drinking and Driving. Mark Johnson and Catalina Kopetz. Health Psychology, Jul 20 2017. doi: 10.1037/hea0000526

Abstract
OBJECTIVE: Alcohol-impaired driving remains a serious public health concern despite the fact that drinking and driving risks are widely disseminated and well understood by the public. This research examines the motivational conditions under which providing risk information can exacerbate rather than decrease potential drinking drivers' willingness to drive while impaired.

METHOD: In a hypothetical drinking and driving scenario, 3 studies investigated participants' self-reported likelihood of drinking and driving as a function of (a) accessibility of information regarding risk associated with drinking and driving, (b) motivation to drive, and (c) need for cognitive closure (NFC).

RESULTS: Across the 3 studies, participants self-reported a higher likelihood of driving when exposed to high-risk information (vs. low-risk information) if they were high in NFC. Risk information did decrease self-reported likelihood of driving among low-NFC participants (Studies 1-3). Furthermore, this effect was exacerbated when the relevant motivation (to get home conveniently) was high (Study 3).

CONCLUSIONS: These findings have important implications for impaired-driving prevention efforts. They suggest that at least under some circumstances, risk information can have unintended negative effects on drinking and driving decisions. The results are consistent with the motivated cognition literature, which suggests that people process and use information in a manner that supports their most accessible and important motivation despite potentially negative consequences.

Understatement of the year: People's ability to judge the veracity of their intuitions may be limited

Can People Judge the Veracity of Their Intuitions? Stefan Leach and Mario Weick. Social Psychological and Personality Science, DOI: https://doi.org/10.1177/1948550617706732

Abstract: People differ in the belief that their intuitions produce good decision outcomes. In the present research, we sought to test the validity of these beliefs by comparing individuals' self-reports with measures of actual intuition performance in a standard implicit learning task, exposing participants to seemingly random letter strings (Studies 1a-b) and social media profile pictures (Study 2) that conformed to an underlying rule or grammar. ***A meta-analysis synthesising the present data (n = 400) and secondary data by Pretz, Totz, and Kaufman (2010) found that people's enduring beliefs in their intuitions were not reflective of actual performance in the implicit learning task. Meanwhile, task-specific confidence in intuition bore no sizable relation with implicit learning performance***, but the observed data favoured neither the Null hypothesis nor the Alternative hypothesis. Together, the present findings suggest that people's ability to judge the veracity of their intuitions may be limited.

Dress and sex -- A majority of girls demonstrated appearance rigidity at least once

Dress and sex: a review of empirical research involving human participants and published in refereed journals. Sharron J. Lennon et al. Fashion and Textiles, December 2017, 4:14, https://link.springer.com/article/10.1186/s40691-017-0101-5

Abstract: Our research purpose was to assess research addressing relationships between dress and sex. Our review was focused on a 25 years span (i.e., 1990–2015) and on empirical research utilizing human participants published in refereed journals. Three main areas of research emerged: (1) dress used as cue to sexual information, (2) dress and sexual violence, and (3) dress, sex, and objectification. Our analyses revealed parents do invest their young children with sex-typed dress however sometimes children demand to wear such dress. Some women intentionally use dress to communicate sexual information but inferences about women who wear sexy dress can be misinterpreted and are sometimes negative. Observers link wearing sexy dress to violence including sexual coercion, sexual harassment, sexual assault, and unwelcome groping, touching, and grabbing. Certain items of sexy dress that reveal the body have been linked to self-objectification. The fit of the items may also contribute to the body revealing nature of clothing styles that elicit self-objectification. The use of sexual images of women and children has increased over time and viewing such images is also linked to self- and other-objectification. Suggestions are provided for future research.

"Appearance rigidity involves insisting on wearing dress items that are closely tied to one sex or avoiding dress items linked to the opposite sex. Few boys demonstrated appearance rigidity, but a majority of girls demonstrated appearance rigidity at least once. Rigidity was linked to children who indicated it was important to them to be a girl or boy (measured using items adapted from adult identity measures). Repeating the study with 4 year old children from ethnically diverse backgrounds, incidents of appearance rigidity were even higher as over half of both the girls and boys demonstrated it."

Connecting the Dots: Illusory Pattern Perception Predicts Belief in Conspiracies and the Supernatural

van Prooijen, J.-W., Douglas, K., and De Inocencio, C. (2017) Connecting the Dots: Illusory Pattern Perception Predicts Belief in Conspiracies and the Supernatural. Eur. J. Soc. Psychol., doi: 10.1002/ejsp.2331

Abstract: A common assumption is that belief in conspiracy theories and supernatural phenomena are grounded in illusory pattern perception. In the present research we systematically tested this assumption. Study 1 revealed that such irrational beliefs are related to perceiving patterns in randomly generated coin toss outcomes. In Study 2, pattern search instructions exerted an indirect effect on irrational beliefs through pattern perception. Study 3 revealed that perceiving patterns in chaotic but not in structured paintings predicted irrational beliefs. In Study 4, we found that agreement with texts supporting paranormal phenomena or conspiracy theories predicted pattern perception. In Study 5, we manipulated belief in a specific conspiracy theory. This manipulation influenced the extent to which people perceive patterns in world events, which in turn predicted unrelated irrational beliefs. We conclude that illusory pattern perception is a central cognitive mechanism accounting for conspiracy theories and supernatural beliefs.

Children acknowledge more negative self-conceptions when motivated to be truthful

Thomaes, S., Brummelman, E. and Sedikides, C. (2017), Why Most Children Think Well of Themselves. Child Dev. doi:10.1111/cdev.12937

Abstract: This research aimed to examine whether and why children hold favorable self-conceptions (total N = 882 Dutch children, ages 8–12). Surveys (Studies 1–2) showed that children report strongly favorable self-conceptions. For example, when describing themselves on an open-ended measure, children mainly provided positive self-conceptions—about four times more than neutral self-conceptions, and about 11 times more than negative self-conceptions. Experiments (Studies 3–4) demonstrated that children report favorable self-conceptions, in part, to live up to social norms idealizing such self-conceptions, and to avoid seeing or presenting themselves negatively. These findings advance understanding of the developing self-concept and its valence: In middle and late childhood, children's self-conceptions are robustly favorable and influenced by both external (social norms) and internal (self-motives) forces.

"When encouraged to respond truthfully, children kept their self-protection motive in check, and acknowledged some of their liabilities or uncertainties" & "at least in childhood, such blindness [to their own faults] may be more motivated than real—children acknowledge more negative self-conceptions when motivated to be truthful."
