We instinctively tend toward solutions that consist of adding something rather than subtracting something, even if the subtraction would be superior

Fillon, Adrien A., Fabien Girandola, Nathalie Bonnardel, and Lionel Souchet. 2022. “People Systematically Overlook Subtractive Changes (2021): Replication and Extension.” PsyArXiv. October 18. doi:10.31234/osf.io/4jkvn

Abstract: People systematically overlook subtractive changes and favor additive ones when generating new ideas. In a preregistered experiment conducted via the Prolific platform among French adults (N = 477), we replicated Experiments 2, 3 and 4 in Adams and colleagues (2021)’s study. We replicated the overlooking of subtraction, as participants generated 1155 additive ideas and only 297 subtractive ideas. Cueing participants (“Remember that you can add things or take them away”) increased the percentage who generated at least one subtractive idea (overall OR = 2.52, improvement condition, ϕ = 0.18, make-it-worse condition, ϕ = 0.24).

Results therefore provided empirical support for the overlooking of subtractive changes hypothesis. We also found that norms affected the generation of new ideas (descriptive OR = 7.49, injunctive OR = 6.86). Cues and injunctive (but not descriptive) norms were both related to the asymmetry.


Men do not find the bodies of apparent greater health and fertility the most attractive bodies; the attractiveness is linked to youth and low parity

The picky men: Men's preference for women's body differed among attractiveness, health, and fertility conditions. Chengyang Han et al. Personality and Individual Differences, Volume 201, February 2023, 111921. https://doi.org/10.1016/j.paid.2022.111921

Abstract: The health and fertility hypothesis suggests that low body weight young women are healthy and fertile, thereby judged as attractive to men. Although it has been widely accepted, few studies have tested the health and fertility hypothesis on a perceptual level, that is whether the most attractive female body is also perceived as the healthiest and most fertile. In the current study, we investigated young and older men's preferences women's body weight, using 3D human body models. With an interactive body preference task, men chose the BMI and body fat of women's body shapes perceived as most attractive, healthiest and most fertile. The results showed that both young and older men had similar patterns of preferences for women's bodies. For BMI, the most attractive body weight was not seen as the healthiest or the most fertile. Compared to the most attractive BMI, higher BMI was required to be seen as the healthiest and this figure was even higher for fertility judgements. Body fat generally showed similar patterns of results as BMI. Our findings challenge the health and fertility hypothesis and point to the alternative explanation that the judgement of women's attractiveness tracks cues indicating youth and low parity.

Introduction

From an evolutionary perspective, sexual selection should have driven men and women to be attracted to cues that would maximize their reproductive success (Buss, 1988; Symons, 1979). For decades, researchers have found several traits that determine physical attractiveness in women, including Body Mass Index (BMI, weight divided by squared height, kg/m2), waist-to-hip ratio, waist-to-stature ratio, lumbar curvature, and leg length (see Lassek & Gaulin, 2016 for a review). Among all of these cues, BMI is argued to be one of the most crucial determinants of the attractiveness of women, as it plays a critical role in many cultures, especially in industrialized societies. Overall, lower values of BMI are found to be seen as attractive in women, although severe underweight is not attractive (Swami, 2015; Tovée et al., 1999).

It has been widely accepted that the preference for low BMI is adaptive because it indicates higher mate value with respect to health, fertility, fecundity, youthfulness, nulliparity and maternal investment (for a review see Bovet, 2019). One explanation that perhaps gets the most attention is the health and fertility hypothesis. Numerous studies have examined this hypothesis by exploring the relationship between BMI and health indicators (Lassek & Gaulin, 2018a) as well as fertility indicators (Lassek & Gaulin, 2018b). Although there is abundant physiological evidence both in support of and against this relationship (see Lassek and Gaulin, 2018a, Lassek and Gaulin, 2018b for reviews), evidence from the perceptual level is rare. Few studies have tested the perceived attractiveness, health and fertility of female bodies at the same time. Although the perceptual evidence is not mandatory for the hypothesis to be valid, it can provide additional support for or against it.

Singh (1993) published an influential study of female attractiveness claiming that attractive bodily features are indicators of women's fertility and health. Since then, most research in the field of female attractiveness has accepted this argument and built on it (Grammer et al., 2003; Marlowe et al., 2005; Weeden & Sabini, 2005). Not surprisingly, this hypothesis has been extended to low BMI which is assumed to signal optimal health and fertility (Tovée et al., 1999). However, recent evidence has cast doubt on these claims and proposed that the low BMI might serve as cues to nubility and reproductive value (Andrews et al., 2017; Lassek and Gaulin, 2019, Lassek and Gaulin, 2021).

In the past few decades, a great deal of research has investigated the BMI values associated with the most attractive female body. In well-nourished populations, it has been consistently found that the most preferred BMIs are around 18–20 (Crossley et al., 2012; Tovée & Cornelissen, 2001; Wang et al., 2015), which are far below the mean or modal values of typical young women in these populations (Lassek and Gaulin, 2016, Lassek and Gaulin, 2018b). This figure is even lower in East-Asian populations, which are 18.43 in Japanese (Swami et al., 2006) and 17.28 in Malaysian Chinese (Stephen & Perera, 2014).

According to the classification of BMI by WHO, the healthy BMI range is 18.5–24.99, BMI < 18.5 is classified as underweight and BMI >25 is classified as overweight. Abundant evidence from epidemiological studies has shown that overweight status is positively related to a series of cardiovascular diseases like diabetes, hypertension, heart attacks and stroke (Aune et al., 2016; Chen et al., 2013; GBD 2015 Obesity Collaborators, 2017; Khan et al., 2018) and some cancers like endometrial, breast, and colon cancer (Bhaskaran et al., 2014). Complementing these findings, a meta-analysis of over 10 million participants has found that all-cause mortality is lowest in the normal BMI range (20–25), whereas BMIs below (BMI < 20) or above the range (BMI > 25) was positively associated with overall mortality (Di Angelantonio et al., 2016). Similarly, a systematic review suggested that normal weight is associated with longer life expectancy compared to underweight and obese status (Bhaskaran et al., 2018). It should be kept in mind that most evidence suggesting the negative relationship between BMI and health is based on well-nourished populations like North American and Europeans.

In sharp contrast, studies of subsistence and forager groups found that plumpness was preferred in these cultures. Female bodies with a substantially high BMI (e.g., BMI ≥ 25) were judged to be attractive (Boothroyd et al., 2016; Swami et al., 2012; Tovée et al., 2006). This preference is especially strong in environments experiencing food scarcity (Anderson et al., 1992). These cultural variations have been attributed to psychological adaptations to local environments where lower BMI tends to be associated with poor health (Swami, 2015; Tovée et al., 2006).

In fact, evidence from subsistence populations indicates an inverse relationship between BMI and health, where the lowest mortality was found in women with high BMI (e.g. BMI > 25) and women with low BMIs have increased mortality rates (Hanson et al., 1995; Hodge et al., 1996; Sear, 2006; Wang & Hoy, 2002). This negative relationship between BMI and mortality might be due to the increased risks of getting infections in women with low BMI. Evidence from hunter-gatherer groups showed that the majority of female death in these populations was caused by infections in women with low BMIs (Strickland & Ulijaszek, 1993). Even in developed areas where people have access to antibiotics, women with low BMIs are more likely to get infections (Flegal et al., 2007; Milner & Beck, 2012). More recently, researchers found further evidence supporting the inverse relationship between BMI and health in women of reproductive age. Using a large U.S. sample dataset, Lassek and Gaulin (2018a) found that women of reproductive age with BMIs lower than 20 have worse health conditions than women with higher BMIs controlling for other factors that possibly affect health. Specifically, they were more likely to have infections, bed disability days, hospital days and more major disabilities.

To sum up, the existing evidence suggests that BMI does relate to health in many ways, where normal weight might be most protective. However, low BMIs, which are preferred by men in well-nourished populations, are linked to relatively higher mortality rates (Aune et al., 2016; Di Angelantonio et al., 2016) and poor health (Lassek & Gaulin, 2018a), not only in subsistence population but also in well-nourished population. This evidence may chanllenge the health and fertility hypothesis which posits that the preferred BMIs are indicators of good health (Tovée et al., 1999).

It is worth noting that nearly all the aforementioned studies are correlational or cross-sectional, one cannot be sure whether it is low or high BMI directly causes these health issues. Furthermore, one should be careful in interpreting the relationship between BMI and health because BMI conflates fat mass and muscle mass. At a given BMI, the body compositions vary between individuals. For example, people with low fat mass and high muscle mass will be classified as overweight by the BMI classification. Yet, higher fat mass is detrimental to health (Gómez-Ambrosi et al., 2011) while higher muscle mass is associated with enhanced fitness and health (Frankenfield et al., 2001; Johnson et al., 2015).

Perhaps the more relevant effect of BMI on health is its association to fertility health. Evidence from a US national longitudinal research showed that infertility rate is highest in underweight and obese women (Jokela et al., 2008). There is evidence suggesting that obesity is related to polycystic ovarian syndrome, a disease that could cause irregular periods, excess androgen levels and policystic ovaries, which in turn cause infertility problems (Barber et al., 2006; Lim et al., 2013; Vrbikova & Hainer, 2009). Compared to normal weight women, obese women are more likely to have miscarriages whether they conceived naturally or following ovulation induction (Lashen et al., 2004; Metwally et al., 2008). Furthermore, obese women have increased risks of birth defects such as neural tube defects, anencephaly, spina bifida, cardiac septal anomalies l and hydrocephaly (Rasmussen et al., 2008; Stothard et al., 2009).

Nonetheless, low body weight is detrimental to fertility health as well. Indeed, considerable evidence has shown that being underweight adversely affects menstrual function, pregnancy outcomes, perinatal outcomes and neonatal outcomes. To begin with, numerous studies have reported that being underweight, or states of energy deprivation like rapid weight loss and excessive physical activity can lead to menstrual dysfunctions like hypothalamic amenorrhoea, then cause infertility (Frisch, 1987, Frisch, 2004; Stokić et al., 2005; Støving et al., 1999). Women who have low BMI (e.g. BMI <19/20) like athletes and those with eating disorders are more likely to develop amenorrhoea, which is due to endocrine alterations, such as lowered estrogen levels (Ackerman & Misra, 2018; Hamilton-Fairley & Taylor, 2003; Ledger & Skull, 2004; Ziomkiewicz et al., 2008). When putting on weight, resumption of menstrual cycles is observed (Ackerman & Misra, 2018; Arends et al., 2012; Swenne, 2004).

More importantly, pregnancy rates were found to decrease with BMI. One study found that in women with BMI < 21, a one-unit BMI decrease was related to 3 % lower pregnancy rate (Van Der Steeg et al., 2008). Wang et al. (2000) showed that underweight women have a lower chance of getting pregnant with assisted reproduction treatment than women with normal BMI.

Even after conception, women with low BMIs are more likely to have negative pregnancy, perinatal and neonatal outcomes. A meta-analysis including different types of conception indicated that prepregnancy underweight is associated with increased risks of miscarriage (Balsells et al., 2016). Complementing that, a large-scale study with 3854 nulliparous women found that the average duration of pregnancy was shorter in underweight women compared to normal weight women (Hoellen et al., 2014). Consequently, preterm deliveries were significantly more common in underweight women. This gestational age difference was even more evident in extremely underweight women (pre-conceptional BMI < 16). As a result, low birth weight is positively linked to prepregnancy underweight status. Similar results were observed in women undergoing in vitro fertilization. Compared to normal weight women, implantation, clinical pregnancy, and ongoing pregnancy rates were lower in underweight women (Tang et al., 2021).

Despite the close relationship between weight and fertility, BMI may not be as closely related to fertility as body fat percentage (BF). Evidence has shown that a certain amount of BF is necessary for maintaining reproductive function. For example, Frisch, 1987, Frisch, 2004 stated that 22 % BF is necessary to maintain normal periods, get pregnant, and lactate. On the contrary, women who have very low BF like female athletes were found to be more likely to experience fertility-related problems like amenorrhoea, anovulation, irregular menstrual cycles, and delayed menarche compared to women with normal BF levels (Klentrou & Plyley, 2003; Redman & Loucks, 2005; Torstveit & Sundgot-Borgen, 2005; Zanker, 2006). In addition, studies have shown that poor nutrition which possibly relates to low BF is linked to delayed menarche (Gluckman & Hanson, 2006; Thomas et al., 2001). In other words, the reproductive span is shorter in women with low BF levels compared to women with normal BF levels.

One study that included healthy reproductive-aged women found that women with very low BF (<22 %) have lower levels of estradiol compared with women with average levels of BF (Ziomkiewicz et al., 2008). Additionally, this study found that a 10 % increase in BF was associated with an increase in estradiol levels. Estradiol plays a critical role in reproductive functions. Lower levels of estradiol decrease pregnancy rates both in healthy naturally conceiving women (Lu et al., 1999; Venners et al., 2006) and in women undergoing in vitro fertilization (Blazar et al., 2004; Chen et al., 2003). Consequently, low BF adversely affects fertility health.

The studies cited above mainly focused on the relationship between BMI and physical health as well as fertility health. Only few studies investigated these relationships from a perceptual perspective, which is how women's body weight affects their perceived health and fertility. Furthermore, to our knowledge, no study has examined the relationship between women's BF and their perceived health and perceived fertility. As noted above, BF might be more important to women's fertility than BMI. Hence, the current study aimed to test the health and fertility hypothesis from a perceptual perspective. Using 3D female body models with varying BMI and BF levels, we attempted to investigate men's preference for women's bodies in three dimensions: the BMI and BF levels found most attractive, the BMI and BF levels perceived to be healthiest, and the BMI and BF levels perceived to be most fertile. The evidence cited above may not support the widespread assumption that men prefer low BMI in female bodies because it indicates better health and fertility. Hence, here we predict that men will choose lower BMI and BF when optimizing attractiveness, than when optimizing the healthy and fertile appearance of women's bodies.

In addition, we also attempted to explore the age effect on body weight preferences under attractiveness, health, and fertility conditions. Previous studies showed mixed results regarding the age effect on the preferences of women's BMI. For example, Sorokowski et al. (2014) found older men preferred higher BMI of women's body than young men do, whereas George et al. (2008) found no effects of age on attractiveness preferences of BMI of women's body. In the literature, older men are generally less picky than younger men when judging women's facial attractiveness (Han et al., 2022; Marcinkowska et al., 2017), which may also present in body weight preferences. Moreover, social media plays an important role in shaping individual's perception of attractiveness, especially the most attractive body weight (Grabe et al., 2008; Swami, 2015). Young adults use social media more than older adults (Sharifian et al., 2021, also see surveys of U.S. adults present by Pew Research Center, 2021). One recent study showed that higher social media use was associated with more negative effects in young adults, but not in older adults (Sharifian et al., 2021). This may indicate that young adults are more influenced by social media than older adults. Slim bodies are frequently exposed in social media. Therefore, we predict that younger men will show stronger preferences for lower BMI and BF of women's body than older men.

Long Social Distancing: More than 10pct of Americans with recent work experience say they will continue social distancing after the COVID-19 pandemic ends, and another 45 pct will do so in limited ways

Long Social Distancing. Jose Maria Barrero, Nicholas Bloom & Steven J. Davis. NBER Working Paper 30568. October 2022. DOI 10.3386/w30568

Abstract: More than ten percent of Americans with recent work experience say they will continue social distancing after the COVID-19 pandemic ends, and another 45 percent will do so in limited ways. We uncover this Long Social Distancing phenomenon in our monthly Survey of Working Arrangements and Attitudes. It is more common among older persons, women, the less educated, those who earn less, and in occupations and industries that require many face-to-face encounters. People who intend to continue social distancing have lower labor force participation – unconditionally, and conditional on demographics and other controls. Regression models that relate outcomes to intentions imply that Long Social Distancing reduced participation by 2.5 percentage points in the first half of 2022. Separate self-assessed causal effects imply a reduction of 2.0 percentage points. The impact on the earnings-weighted participation rate is smaller at about 1.4 percentage points. This drag on participation reduces potential output by nearly one percent and shrinks the college wage premium. Economic reasoning and evidence suggest that Long Social Distancing and its effects will persist for many months or years.


Adaptation to taxation: Corporate income tax changes generate persistent effects on R&D expenditure, productivity and output whereas personal income tax changes trigger large but short-lived responses on the same

Short-Term Tax Cuts, Long-Term Stimulus. James Cloyne, Joseba Martinez, Haroon Mumtaz & Paolo Surico. NBER Working Paper 30246. July 2022. DOI 10.3386/w30246

Abstract: We study the persistent effects of temporary changes in U.S. federal corporate and personal income tax rates using a narrative identification approach. A corporate income tax cut leads to a sustained increase in GDP and productivity, with peak effects between five and eight years. R&D spending and capital investment display hump-shaped responses while hours worked and employment are much less affected. In contrast, personal income tax cuts trigger a short-lived boost to GDP, productivity and hours worked but have no long-term effects. We develop and estimate an endogenous growth model with variable factor utilization and show that these features generate a pro-cyclical response of productivity which is key to account for our empirical findings.

8 Conclusions

Do transitory changes in corporate and personal income taxes have persistent effects on output? And what are the channels? We answer the first question using local projections and narrative-identified tax shocks on post-WWII U.S. data. We answer the second question by running counterfactual simulations from an estimated structural model with endogenous growth, variable factor utilization and distortionary taxes.

Our main findings are that corporate income tax changes generate persistent effects on R&D expenditure, productivity and output whereas personal income tax changes trigger large but short-lived responses of capital expenditure, productivity and output. We show that matching the pro-cyclical response of productivity in the short-run and in the long-run is crucial for the ability of the estimated model to account for the dynamic effects of the two tax shocks on economic activity. Variable labor utilization appears important for replicating the short-term response of productivity and output to a personal income tax change, while R&D expenditure and technological adoption are key to account for the long-term effects of corporate income tax changes.

Female birds disguised as males get extra meals: Around 20% of female hummingbirds have plumage that is characteristic of the males of the species, & this increases access to food resources through mimicry of more aggressive males

Intersexual social dominance mimicry drives female hummingbird polymorphism. Jay J. Falk, Dustin R. Rubenstein, Alejandro Rico-Guevara and Michael S. Webster. Proceedings of the Royal Society B: Biological Sciences, September 7 2022. https://doi.org/10.1098/rspb.2022.0332

Abstract: Female-limited polymorphisms, where females have multiple forms but males have only one, have been described in a variety of animals, yet are difficult to explain because selection typically is expected to decrease rather than maintain diversity. In the white-necked jacobin (Florisuga mellivora), all males and approximately 20% of females express an ornamented plumage type (androchromic), while other females are non-ornamented (heterochromic). Androchrome females benefit from reduced social harassment, but it remains unclear why both morphs persist. Female morphs may represent balanced alternative behavioural strategies, but an alternative hypothesis is that androchrome females are mimicking males. Here, we test a critical prediction of these hypotheses by measuring morphological, physiological and behavioural traits that relate to resource-holding potential (RHP), or competitive ability. In all these traits, we find little difference between female types, but higher RHP in males. These results, together with previous findings in this species, indicate that androchrome females increase access to food resources through mimicry of more aggressive males. Importantly, the mimicry hypothesis provides a clear theoretical pathway for polymorphism maintenance through frequency-dependent selection. Social dominance mimicry, long suspected to operate between species, can therefore also operate within species, leading to polymorphism and perhaps similarities between sexes more generally.

Results revealed significant negative correlations between mindfulness and neuroticism, & trait anxiety, & positive correlation with conscientiousness, but no significant relationship with intelligence

A Meta-Analysis of Trait Mindfulness: Relationships with the Big Five Personality Traits, Intelligence, and Anxiety. Justin T. Banfi, Jason G. Randall. Journal of Research in Personality, October 12 2022, 104307. https://doi.org/10.1016/j.jrp.2022.104307

Abstract: The purpose of this meta-analysis is to evaluate the correlates of trait mindfulness—the tendency to pay attention to the present moment, in a non-judgmental manner—with other individual differences to establish construct validity. We update and expand previous meta-analyses of trait mindfulness with Big Five personality and anxiety with larger samples, unique relationships with broad measures of intelligence, novel moderators, and relative weights analysis. In total, 73,752 participants' data distributed amongst 280 effects were analyzed. Results revealed significant correlations between mindfulness and all personality variables examined, with the strongest effects for neuroticism (ρ = -.53), trait anxiety (ρ = -.50), and conscientiousness (ρ = .42), but no significant relationship with intelligence. Altogether, Big Five variables explained 44% of the variance in trait mindfulness, with neuroticism and conscientiousness demonstrating the strongest influence. These results identify mindfulness as a unique, non-cognitive trait. Moderation analyses revealed negligible effects of sample characteristics (sex, race, age, student status). The scale used to measure mindfulness had a limited influence as well, moderating the correlation between mindfulness and openness alone. Overall, these results provide a clearer picture of the personality profile of mindful individuals and inform meaningful conceptual differences between these constructs.

Non-news Websites Expose People to More Political Content Than News Websites: Evidence from Browsing Data in Three Countries

Wojcieszak, Magdalena, Ericka Menchen-Trevino, Bernhard Clemm von Hohenberg, Sjifra E. de Leeuw, João Gonçalves, Samuel Davidson, and Alexandre Gonçalves. 2022. “Non-news Websites Expose People to More Political Content Than News Websites: Evidence from Browsing Data in Three Countries.” OSF Preprints. October 13. doi:10.31219/osf.io/8et9g

Abstract: Most scholars focus on the prevalence and democratic effects of (partisan) news exposure. This focus misses large parts of online activities of a majority of politically disinterested citizens. Although political content also appears outside of news outlets and may profoundly shape public opinion, its prevalence and effects are under-studied at scale. This project combines three-wave panel survey data from three countries (total N = 6,892) with online behavioral data from the same participants (119.7M visits). We create a multi-lingual classifier to identify political content both in news and outside (e.g. in shopping or entertainment sites). We find that news consumption is infrequent: just 3.4% of participants’ online browsing comprised visits to news sites. Only between 14% (NL) and 36% (US) of these visits were to hard news. The overwhelming majority of participants' visits were to non-news sites. Although only 1.6% of those visits related to politics, in absolute terms, citizens encounter politics more frequently outside of news than within news. Out of every 10 visits to political content, 3 come from news and 7 from non-news sites. Furthermore, non-news exposure to political content had the same – and in some cases stronger - associations with key democratic attitudes and behaviors as news exposure. These findings offer a comprehensive analysis of the online political (not solely news) ecosystem and demonstrate the importance of assessing the prevalence and effects of political content in non-news sources.


Ordinary people too harbor the vision of an utopia or "ideal" society; incorporating science into one's utopia is clearly a minus, except in China, where pro-environmental attitudes are not opposite to science

Profiles of an Ideal Society: The Utopian Visions of Ordinary People. Julian W. Fernando et al. Journal of Cross-Cultural Psychology, Oct 13 2022. https://doi.org/10.1177/00220221221126419

Abstract: Throughout history, people have expressed the desire for an ideal society—a utopia. These imagined societies have motivated action for social change. Recent research has demonstrated this motivational effect among ordinary people in English-speaking countries, but we know little about the specific content of ordinary people’s utopian visions in different cultures. Here we report that a majority of samples from four countries—Australia, China, the United Kingdom, and the United States—converge on a small number of utopian visions: a Modern Green utopia, a Primitivist utopia, a Futurist utopia, and a Religious utopia. Although the prevalence of these utopia profiles differed across countries, there was a cross-cultural convergence in utopian visions. These shared visions may provide common ground for conversations about how to achieve a better future across cultural borders.

We believe that it would benefit ourselves more than others if we succeeded in becoming a better person

Sun, Jessie, Joshua A. Wilt, Peter Meindl, Hanne M. Watkins, and Geoffrey Goodwin. 2022. “How and Why People Want to Be More Moral.” PsyArXiv. October 13. doi:10.31234/osf.io/6smzh

Abstract: What types of moral improvements do people wish to make? Do they hope to become more good, or less bad? Do they wish to be more caring? More honest? More loyal? And why exactly do they want to become more moral? Presumably, most people want to improve their morality because this would benefit others, but is this in fact their primary motivation? Here, we begin to investigate these questions. Across two large, preregistered studies (N = 1,818), participants provided open-ended descriptions of one change they could make in order to become more moral; they then reported their beliefs about and motives for this change. In both studies, people most frequently expressed desires to improve their compassion and more often framed their moral improvement goals in terms of amplifying good behaviors than curbing bad ones. The strongest predictor of moral motivation was the extent to which people believed that making the change would have positive consequences for their own well-being. Together, these studies provide rich descriptive insights into how ordinary people want to be more moral, and show that they are particularly motivated to do so for their own sake.

Irrespective of their therapeutic orientation, psychotherapists overestimated the proportion of patients recovering or improving, & and underestimated the proportion of patients not changing or deteriorating

Attitudes of psychotherapists towards their own performance and the role of the social comparison group: The self-assessment bias in psychodynamic, humanistic, systemic, and behavioral therapists. Thomas Probst, Elke Humer, Andrea Jesser and Christoph Pieh. Front. Psychol., October 13 2022. https://doi.org/10.3389/fpsyg.2022.966947

Abstract: Studies report that psychotherapists overestimate their own performance (self-assessment bias). This study aimed to examine if the self-assessment bias in psychotherapists differs between therapeutic orientations and/or between social comparison groups. Psychotherapists gave subjective estimations of their professional performance (0–100 scale from poorest to best performance) compared to two social comparison groups (“all psychotherapists” vs. “psychotherapists with the same therapeutic approach”). They further rated the proportion of their patients recovering, improving, not changing, or deteriorating. In total, N = 229 Austrian psychotherapists (n = 39 psychodynamic, n = 121 humanistic, n = 48 systemic, n = 21 behavioral) participated in the online survey. Psychotherapists rated their own performance on average at M = 79.11 relative to “all psychotherapists” vs. at M = 77.76 relative to “psychotherapists with the same therapeutic approach” (p < 0.05). This was not significantly different between therapeutic orientations. A significant interaction between social comparison group and therapeutic orientation (p < 0.05) revealed a drop of self-assessement bias in social comparison group “same approach” vs. “all psychotherapists” in psychodynamic and humanistic therapists (p < 0.05). Psychotherapists overestimated the proportion of patients recovering (M = 44.76%), improving (M = 43.73%) and underestimated the proportion of patients not changing (M = 9.86%) and deteriorating (M = 1.64%), with no differences between orientations. The self-assessment bias did not differ between therapeutic orientations, but the social comparison group appears to be an important variable. A major drawback is that results have not been connected to patient-reported outcome or objectively rated performance parameters.


When asked at what income level one is "rich," even the wealthiest state a higher figure than they themselves earn; they tink they belong to the middle class

The psychology of income wealth threshold estimations: A registered report. Robin Rinn, Anand Krishna, Roland Deutsch. British Journal of Social Psychology, October 11 2022. https://doi.org/10.1111/bjso.12581

Abstract: How do people estimate the income that is needed to be rich? Two correlative survey studies (Study 1 and 2, N = 568) and one registered experimental study (Study 3, N = 500) examined the cognitive mechanisms that are used to derive an answer to this question. We tested whether individuals use their personal income (PI) as a self-generated anchor to derive an estimate of the income needed to be rich (= income wealth threshold estimation, IWTE). On a bivariate level, we found the expected positive relationship between one's PI and IWTE and, in line with previous findings, we found that people do not consider themselves rich. Furthermore, we predicted that individuals additionally use information about their social status within their social circles to make an IWTE. The findings from study 2 support this notion and show that only self-reported high-income individuals show different IWTEs depending on relative social status: Individuals in this group who self-reported a high status produced higher IWTEs than individuals who self-reported low status. The registered experimental study could not replicate this pattern robustly, although the results trended non-significantly in the same direction. Together, the findings revealed that the income of individuals as well as the social environment are used as sources of information to make IWTE judgements, although they are likely not the only important predictors.

Does Economic Growth Meaningfully Improve Well-being? An Optimistic Re-Analysis of Easterlin’s Research

Does Economic Growth Meaningfully Improve Well-being? An Optimistic Re-Analysis of Easterlin’s Research: Founders Pledge. Vadim Albinsky. Effective Altruism Forum, Sep 2022. https://forum.effectivealtruism.org/posts/coryFCkmcMKdJb7Pz/does-economic-growth-meaningfully-improve-well-being-an


Summary

Understanding the relationship between wellbeing and economic growth is a topic that is of key importance to Effective Altruism (e.g. see Hillebrandt and Hallstead, Clare and Goth). In particular, a key disagreement regards the Easterlin Paradox; the finding that happiness[1] varies with income across countries and between individuals, but does not seem to vary significantly with a country’s income as it changes over time. Michael Plant recently wrote an excellent post summarizing this research. He ends up mostly agreeing with Richard Easterlin’s latest paper arguing that the Easterlin Paradox still holds; suggesting that we should look to approaches other than economic growth to boost happiness. I agree with Michael Plant that life satisfaction is a valid and reliable measure, that it should be a key goal of policy and philanthropy, and that boosting income does not increase it as much as we might naively expect. In fact, we at Founders Pledge highly value and regularly use Michael Plant’s and Happier Lives Institute’s (HLI) research; and we believe income is only a small part of what interventions should aim at. However, my interpretation of the practical implications of Easterlin’s research differ from Easterlin’s in three ways which I argue in this post:


-  Easterlin finds small coefficients in his preferred regressions of changes in countries’ happiness on changes in GDP. He concludes that these coefficients have low “economic significance” and that increasing economic growth is not a good way to make people happier. However, even if we take these coefficients at face value, they still represent a very meaningful increase in wellbeing within the effective altruism framework, consistent with the impacts of unconditional cash transfers on individuals. The benefits become very large when aggregated across all the people in a country for many years.

-  We also have reason to doubt Easterlin’s results, in that they are highly sensitive to small changes in methodology. We perform two variations on his regression that fully accept his methodology of only including “full cycle” countries, but update it slightly, reversing the result. If we replicate his results counting one more country as a “transition” economy, the Easterlin paradox largely disappears. If we repeat his analysis with new data from 2020 instead of 2019, the paradox also seems to largely disappear.

-  It may be difficult to find things we can influence whose change over time will have a higher correlation to a country’s change in happiness than changes in GDP. Even if we accept that boosting GDP does not meaningfully increase happiness, other potential means of boosting national happiness may increase it even less. If we rerun Easterlin’s analysis using three interventions Easterlin and Plant suggest (health, pollution, and a comprehensive welfare state), their implied impacts on national happiness are much smaller than the impacts for GDP or negative. However, I have low confidence in this conclusion, and think it is a very valuable project to identify the interventions that are most likely to have an impact on happiness.

3. The happiness impact of alternative interventions is smaller than the impact of GDP.

Easterlin concludes his latest paper by suggesting that even though he does not believe that GDP growth has a meaningful impact on happiness, that there are a number of better interventions. Michael Plant adds some suggestions to the list in his post, coming up with a set of potential interventions that includes:

“...job security, a comprehensive welfare state, getting citizens to be healthy, and encouraging long-term relationships…[taking] mental health and palliative care more seriously…improved air quality, reduced noise, more green and blue space (blue spaces being water), and getting people to commute smaller distances (Diener et al. 2019). Social interactions could be enhanced via urban design, reducing corruption, increasing transparency, supporting healthy family relationships, and maybe even things like progressive taxation.”

All of these sound like promising ideas, and are a good research agenda for future investigation. However, it may be difficult to find one of these measures that has a higher impact on country-level happiness than GDP using Easterlin’s methodology. To perform an exploratory analysis, I start with Easterlin’s data from his “best possible life” regression (taking his relatively low estimated impacts at face value as I do in section 1.) I then choose three interventions from Michael Plant’s list that seem to have a fair amount of annual data available on OurWorldInData.org: health, pollution and a comprehensive welfare state.[7] I replace annual GDP growth in Easterlin’s regression with annual growth on these three metrics, and perform a separate analysis for each one.[8] Each regression looks at annualized changes in a country’s Cantril ladders scores versus annualized changes in the specified metric for the past 12-14 years. The health regression estimates how much a decrease in the number of years people in a country lose to ill health corresponds to increases in happiness. This regression produces coefficients that are either an order of magnitude smaller than the GDP regression, or negative, depending on whether we exclude countries that have less than 12 years of data. In both cases the r-squared of the regression is essentially 0.. There does not appear to be a way to interpret these results to suggest that changes in health have a higher impact on national happiness than changes in GDP. The pollution regression repeats the methodology for health, but looks at only the changes in the years of life lost to pollution. This analysis actually shows negative results of a magnitude similar to the positive results of the GDP regression. This would imply that increases in pollution are actually associated with countries getting happier. For example, the Republic of Congo and Benin both had large annual increases in happiness despite increasing levels of pollution.[9] The comprehensive welfare state regression examines the impact of changes in a score of whether a country has an adequate safety net. This analysis also shows negative results, however there are very few countries and years for which this data is available and the data appears to be of low quality, suggesting that we should not read too much into this result. In all three of these analyses we do not find any evidence consistent with any of these metrics having a higher impact on national happiness than changes in GDP.

I do not have a high level of confidence in these initial results. There are likely better sources of data, and better methodologies to employ. However, I do think they suggest that it may be difficult to find any interventions of their kind which will imply a larger impact on happiness than GDP using Easterlin’s methodology.

Normies do not experience "duping delight," the triumph of successful lying, but individuals with dark personality traits seem to enjoy it

In Search of Duping Delight. Christopher A. Gunderson et al. Affective Science (2022) 3:519–527. July 19 2022. https://link.springer.com/epdf/10.1007/s42761-022-00126-5?sharing_token=UDARajZZMOajsQOWajroRPe4RwlQNchNByi7wbcMAY4DvTiS0pewgUgjHUGHF-j8tun13uPLn0O4pzl2ZLfzKIaL7mGS7mgTPcoOOvxPoS0cEJiQ_KVmG43HkaTQYNUo9ipPDnldxhCSzE8HYHFl9lbBaLFNHzToXmNnToT9Jgg%3D

Abstract: Deception has long been assumed to conjure diverse affective experiences (Trovillo, 1938). Liars, more than truth-tellers, are theorized to feel guilt, fear, and nervousness (e.g., Ekman, 1985; Zuckerman et al., 1981). Additionally, deception has been proposed to elicit positive affect. Ekman (1985) broadly defined duping delight as any positive affective experience that occurs in anticipation of, during, or following a lie. Empirical evidence for this definition of duping delight has primarily come from studies of affective cues during deceptive acts. For example, in a study of emotional, high-stakes lies in which people pleaded for help to find a person they had recently murdered, smiles were described by ten Brinke and Porter (2012) as a sign of duping delight. However, research suggests that smiles may occur for multiple reasons (e.g., to signal affiliation or dominance; Martin et al., 2017). Given the difficulty in inferring affective states from facial expressions (Barrett et al., 2019), a more direct approach would ask liars and truth-tellers to report on their affect.

Discussion
In the two studies, we sought experimental evidence that successful deception would result in duping delight. Across both studies, receiving affirming feedback about one’s believability increased positive affect. Believability feedback, however, did not interact with veracity to predict positive affect: Successful (vs. unsuccessful) liars did not report greater positive affect. However, we did find that liars who reported moderate and high (but not low) Machiavellianism and narcissism reported more positive affect after receiving affirming feedback, suggesting that personality variables may be an important predictor of who experiences duping delight. Although these findings suggest that duping delight may be a less common response to successful deception than previously theorized, it should be noted that Ekman and Frank (1993) proposed additional conditions for producing duping delight that were not part of our paradigm. While our paradigm involved a lie that caused no harm to others (Ruedy et al., 2013), the present study lacked an audience to witness the lie and a “victim” who has a reputation of being hard to trick (Ekman & Frank, 1993). That said, we did directly test one potential moderator of the experience of duping delight in Study 2, specifically whether the lie was goal conducive. We attempted to manipulate goal congruence by including an incentive condition, which provided a tangible reward for successful lying (or truth-telling). However, we found no effect of incentive. Although these findings may suggest that our incentive was not large enough to impact affective experiences, these results are consistent with previous research on conceptually similar cheating behavior: positive affect is elicited whether cheating is self-selected or sanctioned by experimental manipulation and was unrelated to the size of financial incentive gained by cheating (Ruedy et al., 2013). Alternatively, it is possible that duping delight is only experienced by a subset of the population. For example, individuals with high levels of “dark” personality traits have been observed to lie more and report duping delight as a motivator for their deception (Jonason et al., 2014; Spidel et al., 2011). Indeed, duping delight might serve as positive reinforcement for these individuals, resulting in their prolific use of deception. The results in Study 2 indicate that Machiavellianism and narcissism moderated the effect of positive affect after receiving believable (vs. not believable) feedback after lying. This is consistent with previous work suggesting that “dark” personality traits are positively associated with lying and unethical behavior across various situations (Azizli et al., 2016; Baughman et al., 2014; Elaad et al., 2020) and positive attitudes about deceptive communication (Oliveira & Levine, 2008). Future research should continue to explore the effects of personality and situational variables (e.g., Markowitz & Levine, 2021) with consideration for a typology of lies (Cantarero et al., 2018) that may elicit different affective experiences while lying. To date, much of the research on duping delight in the deception literature has been focused on how this affective experience might give rise to behavioral cues to deception (e.g., Ekman, 1985; ten Brinke & Porter, 2012). The current research advances theorizing about duping delight by testing some of the proposed moderators of this experience and considering how this affective experience may reinforce and exacerbate the use of deception in social life. Additional research on duping delight will allow for a richer understanding of how and why people choose to lie, and whether this affective experience acts as an affective “reward” that affects deception frequency over time.

The association between "cheaper" non-marital sex partners and marriage rates is temporary: recent sex partners predict lower odds of marriage, but not lifetime non-marital sex partners; it is not "the" reason for declining marriage rates

Does a longer sexual resume affect marriage rates? Nicholas H. Wolfinger, Samuel L. Perry. Social Science Research, October 11 2022, 102800. https://doi.org/10.1016/j.ssresearch.2022.102800

Abstract: Sociologists have proposed numerous theories for declining marriage rates in the United States, often highlighting demographic, economic, and cultural factors. One controversial theory contends that having multiple non-marital sex partners reduces traditional incentives for men to get married and simultaneously undermines their prospects in the marriage market. For women, multiple partners purportedly reduces their desirability as spouses by evoking a gendered double-standard about promiscuity. Though previous studies have shown that having multiple premarital sex partners is negatively associated with marital quality and stability, to date no research has examined whether having multiple non-marital sex partners affects marriage rates. Data from four waves of the National Survey of Family Growth reveal that American women who report more sex partners are less likely to get married by the time of the survey (though so too were virgins). Yet this finding is potentially misleading given the retrospective and cross-sectional nature of the data. Seventeen waves of prospective data from the National Longitudinal Survey of Youth's 1997 mixed-gender cohort that extend through 2015 show the association between non-marital sex partners and marriage rates is temporary: recent sex partners predict lower odds of marriage, but not lifetime non-marital sex partners. Seemingly unrelated bivariate probit models suggest the short-term association likely reflects a causal effect. Our findings ultimately cast doubt on recent scholarship that has implicated the ready availability of casual sex in the retreat from marriage. Rather, the effect of multiple sex partners on marriage rates is “seasonal” for most Americans.


Introduction

As more Americans choose to delay marriage or forego it altogether (Bloome and Ang, 2020), sociologists have offered a number of explanations. These have included the falling economic prospects of men and the stronger economic prospects of women, which weakened the latter's incentives; rising expectations of consumption for the middle class; the growing cultural value of achieving economic stability before marriage; and creeping disenchantment with the idea of life-long commitment (Carr and Utz, 2020; Cherlin, 2020; Edin and Kefalas, 2011; England, 2018; Kuperberg, 2019; Schneider et al., 2018; Smock et al., 2005). A more controversial theory for declining marriage rates is the idea that the broad acceptance and availability of non-marital sexual activity (and, to a lesser extent, masturbatory pornography use) has made marriage less necessary or even desirable (Caldwell, 2020; Regnerus, 2017; Regnerus and Uecker, 2011; for critiques, see Bridges et al., 2018; Perry, 2020; Risman, 2019).1

To be sure, scholars who support the latter theory acknowledge that the vast majority of people who marry do so for non-sexual reasons, since most couples have sex before marriage. Nonetheless, in a world where one can have casual sex with little to no commitment, the argument goes that some men and women will simply have one less traditional incentive to get married, as well as less incentive to become the kind of person who is “marriage material” (as evidenced either by superior economic prospects or chaste reputation) (Baumeister and Vohs, 2012; Buss and Schmitt, 2011; Caldwell, 2020; Huang et al., 2011; Malcolm and Naufal, 2016; Regnerus, 2017, 2019; Regnerus and Uecker, 2011).

Though this theory rests upon debatable premises (e.g., gendered assumptions about desire for sexual activity, the extent to which people exchange long-term commitments for sexual activity or vice versa, the consistent coupling of sex and marriage), the broad empirical claim itself has yet to be definitively examined. Specifically, is there evidence that never-married persons with multiple sex partners (indicating they not only can, but do more readily access sexual activity with less long-term commitment) are less likely to get married? Despite decades of references to this idea, no study has tried to test it using representative data. This neglect is especially curious given that the theory is consistent with pervasive cultural tropes arguing why young women in particular need to withhold sex: frequent sex partners purportedly render women less desirable, and, if men could get sex without commitment, they might be less motivated to marry and less motivated to develop their prospects to establish their eligibility for marriage—in other words, the “why buy the cow when you can get the milk for free” theory (Baumeister and Vohs, 2012; Huang et al., 2011; Regnerus, 2017; Regnerus and Uecker, 2011).

Addressing this gap in the literature, we draw on data from both the National Survey of Family Growth (NSFG) and the National Longitudinal Survey of Youth (NLSY97) to assess how the number of Americans’ non-marital sex partners predicts their likelihood of marrying. Using cross-sectional data from the NSFG, our preliminary findings suggest that never-married women who recount more sex partners (as well as those with no sex partners) are less likely to get married by the time of the survey. The NSFG is limited in several ways—repeated cross-sectional data, sexual history only available for women, retrospective measure of the number of sex partners—so we turn to the NLSY97 and its 17 waves of prospective data extending from 1997 to 2015. We find that the recent number of sex partners is associated with a reduction in the odds of marriage, but lifetime sex partners is not, indicating the link between more sex partners and likelihood of marriage is temporary. Seeking to disentangle self-selection versus “treatment” effects, seemingly unrelated bivariate probit models suggest that the short-term effect is likely causal. We propose that the effect of multiple sex partners on the likelihood of marriage is seasonal, reflecting a period where the persons are enjoying sexual activity with less commitment. Yet having multiple sex partners does not seem to discernibly influence their odds of marriage in the long run.

Our findings extend sociologists' understanding of the link between non-marital sexual activity and marriage in several ways. First and foremost, our findings cast doubt on the controversial notion that more readily available sexual activity with numerous partners will reduce men's and women's desire or desirability, and ultimately, likelihood of marrying. Though the “seasonal” effect of having multiple sex partners may contribute to delayed marriage, declining rates of marriage cannot be broadly explained by access to “cheap sex,” especially in light of the fact that sex frequency and the number of sex partners is declining among young people (Lei and South, 2021; Twenge et al., 2017). Our study also shows that the sexual activity of single women does not appear to make them “undesirable” as marriage partners. Although heterosexual women have historically been stigmatized for having casual sex (Allison and Risman, 2014; Armstrong et al., 2012; England and Bearak, 2014), our analyses suggest that this does not manifest itself in long-term singleness. Women with multiple sex partners are just as likely to get married as are virgins, if somewhat later. Our findings ultimately underscore the continued decoupling of sexual history from marriage rates per se (D'Emilio and Freedman, 2012), instead highlighting how seasons of sexual exploration with different partners may simply contribute to postponing a relationship most Americans still anticipate and, ultimately, form (Newport and Wilke 2013; Parker and Stepler, 2017).

They found no systematic effect of stress on prosocial behaviours

Effect of mood and worker incentives on workplace productivity. Decio Coviello, Erika Deserranno, Nicola Persico, Paola Sapienza. The Journal of Law, Economics, and Organization, ewac017, September 26 2022. https://doi.org/10.1093/jleo/ewac017

Abstract: We study the causal effect of mood on the productivity of call-center workers. Mood is measured through an online “mood questionnaire” which the workers are encouraged to fill out daily. We find that better mood actually decreases worker productivity for workers whose compensation is largely fixed. The negative effect of mood is attenuated for workers whose compensation is based on performance (high-powered incentives). This finding holds both at a correlational level and in two IV settings, where mood is instrumented for by weather or, alternatively, by whether the local professional sports team played/won the day before. We rule out a number of threats to the exclusion restrictions, and discuss the mechanisms that could generate our findings

Sleeping poorly is robustly associated with a tendency to engage in spontaneous waking thought

Sleeping poorly is robustly associated with a tendency to engage in spontaneous waking thought. Ana Lucía Cárdenas-Egúsquiza, Dorthe Berntsen. Consciousness and Cognition, Volume 105, October 2022, 103401. https://doi.org/10.1016/j.concog.2022.103401

Highlights
•    A comprehensive study on the relationship between self-reported sleep and spontaneous thought tendencies.
•    A wide variety of sleep and spontaneous thoughts measures were included.
•    Sleep predicted spontaneous thoughts tendencies, controlling for trait negative affect.
•    Sleep did not predict the frequency of positive-constructive spontaneous thought.
•    Findings demonstrate the unique role of sleep in relation to spontaneous cognition.

Abstract: We spend approximately-one third of our lives sleeping, and spontaneous thoughts dominate around 20–50% of our waking life, but little is known about the relation between the two. Studies examining this relationship measured only certain aspects of sleep and certain forms of spontaneous thought, which is problematic given the heterogeneity of both conceptions. The scarce literature suggests that disturbed sleep and the frequency of spontaneous waking thoughts are associated, however this could be caused by shared variance with negative affect. We report a comprehensive survey study with a large range of self-reported sleep and spontaneous thought measures (N = 236), showing that poorer sleep quality, more daytime-sleepiness, and more insomnia symptoms, consistently predicted higher tendencies to engage in disruptive spontaneous thoughts, independently of trait negative affect, age and gender. Contrarily, only daytime sleepiness predicted positive-constructive daydreaming. Findings underscore the role of sleep for spontaneous cognition tendencies.

4. Discussion

We examined associations between different self-reported aspects of sleep, a variety of spontaneous thoughts tendencies and trait affect in a comprehensive survey study. The findings generally agreed with our predictions. First, subjective measures of disturbed sleep were consistently associated with higher tendencies to engage in disruptive spontaneous thoughts, but not positive constructive daydreaming. Second, subjective measures of disturbed sleep were associated with higher tendencies toward negative affect and lower tendencies to positive affect. Third, higher tendencies to engage in disruptive spontaneous thoughts were related to higher trait negative affect, whereas a tendency toward positive constructive daydreaming was related only to more positive affect. Fourth, subjective measures of disturbed sleep were significant predictors of disruptive, and, especially, poor attention-related spontaneous thoughts, above and beyond negative affect tendencies, age and gender. The emotionally valenced daydreaming styles showed different patterns: a tendency toward positive constructive daydreaming was predicted only by subjective daytime sleepiness. A tendency toward guilt-fear of failure daydreaming was not predicted by any of the subjective sleep measures, but it was predicted by higher negative affect tendencies.

The study adds to the literature by showing that the relationship between self-reported disturbed sleep and the tendency to engage in disruptive spontaneous thoughts is not driven solely by negative affect. Self-reported sleep quality, daytime sleepiness, and insomnia symptoms predicted a tendency to engage in various forms of spontaneous thoughts, beyond negative affect tendencies, age and gender. This suggests other mechanisms behind the relationship between subjective sleep and spontaneous thought tendencies, besides shared associations with negative affect. First, self-reported poor sleep quality (Nebes, Buysse, Halligan, Houck, & Monk, 2009), insomnia (Liu et al., 2014) and daytime sleepiness (Anderson, Storfer-Isser, Taylor, Rosen, & Redline, 2009) have been related to reduced executive cognitive control. Impaired executive control in people suffering from disturbed sleep could reduce their ability to prevent the mind from wandering. This is consistent with the executive-failure account of mind wandering, which proposes that mind wandering episodes occur due to failures in the executive control system (McVay & Kane, 2010). Second, poor sleep quality, insomnia symptoms and daytime sleepiness have been associated with disrupted connectivity of the resting state, default mode network (DMN, Killgore., 2015, Nie et al., 2015, Tashjian et al., 2018). Poor sleep has also been associated with altered connectivity of attentional networks (Tomasi et al., 2009). Speculatively, both changes may be associated with an increased tendency to engage in mind wandering (e.g., Christoff et al., 2009, Poerio et al., 2017, Van Calster et al., 2017). Third, poor sleep quality increases sleep pressure (i.e. the increasing need for sleep per time awake) and this, in turn, increases the occurrence of local sleep-like activity in specific brain areas and networks involved in specific tasks (Cajochen et al., 1995, Muto et al., 2016). Local sleep-like activity in task-specific brain areas has been proposed as a neurophysiological marker of mind wandering experiences (Andrillon et al., 2019, Jubera-Garcia et al., 2021). Another speculative possibility is that an increase in the tendency for experiencing spontaneous thoughts may be a compensatory or restorative response to a lack of good sleep, equivalent to REM-sleep compensation (Carciofo et al., 2014b, Scullin and Gao, 2018). Finally, pressing current concerns, such as financial or social problems or recent stressful events, may influence sleep quality and/or cause insomnia (Van Laethem et al., 2015) and at the same time increase the tendency to engage in spontaneous thought when being awake (Klinger, 2009). Further research is needed to clarify whether and how these mechanisms interact with one another to regulate the tendency for experiencing spontaneous thoughts.

The tendency to engage in positive constructive daydreaming was not associated with, nor predicted by, any of the disturbed sleep measures, except for daytime sleepiness. This is consistent with previous research that failed to find an association between sleep quality and problem-solving daydreaming (Carciofo et al., 2014b, Denis and Poerio, 2017); between insomnia and positive constructive daydreaming (Starker and Hasenfeld, 1976, Starker, 1985) and between a tendency towards eveningness and problem-solving daydreaming (Carciofo et al., 2014b). These findings agree with the view that positive constructive daydreaming is a distinct form of spontaneous thought. It may serve as a source of problem solving, future planning, creativity and fantasy (Antrobus et al., 1966, Huba et al., 1977, Singer, 1966), as well as being related to compassion, simulating another person’s perspective and deriving meaning from events and experiences (Immordino-Yang, Christodoulou, & Singh, 2012). Therefore, and as suggested by Cárdenas-Egúsquiza and Berntsen (2022), positive constructive daydreaming may differ from disruptive spontaneous thoughts by at least two specific features. First, people who report higher tendencies to engage in positive constructive daydreaming also report higher tendencies toward positive affect, showing that this type of spontaneous thought is related to positively valenced emotions (Carciofo et al., 2014b), whereas most other forms of spontaneous thought are associated with negative affectivity (e.g., Killingsworth & Gilbert, 2010). Second, positive constructive daydreams may more often be initiated intentionally (Seli et al., 2016, Seli et al., 2017). People may frequently engage in positive daydreaming, such as planning an activity or solving a problem, in a deliberative fashion, which would then require executive functions to decouple from a current task or activity in order to sustain the daydream (Smallwood, 2013, Smallwood and Schooler, 2006).

In this line, one would expect people reporting disturbed sleep to show lower tendencies to engage in positive constructive daydreaming, due to reduced executive functioning. This is consistent with Carciofo et al. (2014b) who found more subjective daytime sleepiness related to less problem solving daydreaming. In the present study, however, we unexpectedly found more daytime sleepiness to be associated with higher tendencies to engage in positive constructive daydreaming. This discrepancy may reflect that the measure used in the present study assessed a broader concept of positive constructive daydreaming (i.e. fantasy, imagination, vivid imagery; McMillan et al., 2013) than problem solving and future planning as examined by Carciofo et al. (2014b).

The raw correlations showed consistent associations between self-reported measures of disturbed sleep and tendencies to engage in guilt-fear of failure daydreaming. However, disturbed sleep measures did not predict guilt-fear of failure daydreaming when controlling for negative affect tendencies in the regression analyses. This suggests that the association between self-reported insomnia symptoms and guilt-fear of failure daydreaming found in previous research (Starker, 1985, Starker and Hasenfeld, 1976) might have been driven by negative affectivity and not by insomnia symptomatology itself. This would be consistent with the maladaptive and negatively valenced nature of the guilt and fear-of-failure daydreaming style, which involves depressing, frightening and panicking daydreams related to fearing and failing responsibilities, failing loved ones, aggressing others and lying (Antrobus et al., 1966, Huba et al., 1977, McMillan et al., 2013, Singer, 1966).

Finally, younger age appeared to be a robust predictor of higher tendencies to engage in all the spontaneous thoughts measured in this study, except for involuntary mental time travel. This supports prior observations of decreased prevalence of mind wandering and daydreaming in older adults (Berntsen et al., 2015), and a less clear age-related decline for involuntary remembering (Berntsen et al., 2017, Maillet and Schacter, 2016).

The present study holds limitations. First, the cross-sectional and self-report nature of our data prevents reasoning about causality as well as generalizability to experimental studies. Here we used subjective measures of sleep, spontaneous thoughts and affectivity. We acknowledge that trait and state-level measures capture different aspects of the same phenomenon. However, we note that our results agree with previous survey and experimental studies measuring both trait and state-level sleep and spontaneous cognition (Cárdenas-Egúsquiza & Berntsen, 2022). Nonetheless, a bidirectional relationship in which the tendency to engage in spontaneous thoughts predicts the quality and duration of sleep is a possibility that should be further explored (Marcusson-Clavertz et al., 2019). Second, the influence of sleep duration (considered an aspect of sleep quality, Buysse et al., 1989, Kline, 2013) on the frequency of spontaneous thoughts was not examined in depth in the present study (but see the Supplementary Material Table S1 on correlations with sleep duration) and previous research has revealed inconsistent results (Robison et al., 2020, Walker and Trick, 2018). Third, we only applied the widely used PANAS to assess trait negative affectivity and its relation to spontaneous thoughts and sleep outcomes. However, other measures strongly related to negative affect, such as trait neuroticism, have been associated with more mind wandering, poorer sleep quality and a tendency towards eveningness (Carciofo, 2020, Carciofo and Jiang, 2021, Carciofo et al., 2016). Lastly, we acknowledge that the data were collected in November 2020, when lockdown restrictions to reduce the spread of the Covid-19 virus were still in place in several states in the United States of America, which may have influenced the findings (Leone et al., 2020, Simor et al., 2021). However, most of our results are consistent with previous research performed before the Covid-19 pandemic, suggesting that the relationships between subjective sleep outcomes and the tendency to engage in spontaneous thoughts are not contextual and seem to remain even during unusual situations.

Aversion to Low-Probability Gains, even with no possibility of money loss

Opportunity Neglect: An Aversion to Low-Probability Gains. Emily Prinsloo et al. Psychological Science, Sep 26 2022. https://doi.org/10.1177/09567976221091801

Abstract: Seven preregistered studies (N = 2,890, adult participants) conducted in the field, in the lab, and online documented opportunity neglect: a tendency to reject opportunities with low probability of success even when they come with little or no objective cost (e.g., time, money, reputation). Participants rejected a low-probability opportunity in an everyday context (Study 1). Participants also rejected incentive-compatible gambles with positive expected value—for both goods (Study 2) and money (Studies 3–7)—even with no possibility of monetary loss and nontrivial rewards (e.g., a 1% chance at $99). Participants rejected low-probability opportunities more frequently than high-probability opportunities with equal expected value (Study 3). Although taking some real-life opportunities comes with costs, we show that people are even willing to incur costs to opt out of low-probability opportunities (Study 4). Opportunity neglect can be mitigated by highlighting that rejecting an opportunity is equivalent to choosing a zero probability of success (Studies 6–7).

Abstract: In this chapter, we argue that evolutionary perspectives on atheism have been constrained by a methodological commitment that places atheists at the low end of a religiosity continuum and/or assumes they are psychologically atypical because of their rejection of religious beliefs, if truly rejecting religious beliefs is even possible. In contrast to those positions, we explore the possibility that, like religious belief, atheistic belief could be defined in “positive” terms, linked to evolved psychological mechanisms, and used to produce individual evolutionarily adaptive outcomes. Thus, we review the methodological considerations pertinent to the development of this position and used these to frame the influx of scientific research on atheism conducted over the past several years.

Market-integrated participants display universalism in moral decision-making, & non-market participants make more moral decisions towards co-villagers

Market Participation and Moral Decision-Making: Experimental Evidence from Greenland. Gustav Agneman, Esther Chevrot-Bianco. The Economic Journal, ueac069, September 23 2022. https://doi.org/10.1093/ej/ueac069

Abstract: The relationship between market participation and moral values is the object of a long-lasting debate in economics, yet field evidence is mainly based on cross-cultural studies. We conduct rule-breaking experiments in 13 villages across Greenland (N=543), where stark contrasts in market participation within villages allow us to examine the relationship between market participation and moral decision-making holding village-level factors constant. First, we document a robust positive association between market participation and moral behaviour towards anonymous others. Second, market-integrated participants display universalism in moral decision-making, whereas non-market participants make more moral decisions towards co-villagers. A battery of robustness tests confirms that the behavioural differences between market and non-market participants are not driven by socioeconomic variables, childhood background, cultural identities, kinship structure, global connectedness, and exposure to religious and political institutions.

Do Children Cause the Cognitive Stimulation They Receive? Modelling the Direction of Causality

Oginni, Olakunle, and Sophie von Stumm. 2022. “Do Children Cause the Cognitive Stimulation They Receive? Modelling the Direction of Causality.” PsyArXiv. October 8. psyarxiv.com/pqf78

Abstract

We tested the directionality of associations between children’s early-life cognitive development and the cognitive stimulation that they received from their parents. Our sample included up to 15,314 children from the Twins Early Development Study (TEDS), who were born between 1994 and 1996 and assessed at age 3 and 4 years on cognitive development and cognitive stimulation, including singing rhymes, reading books, and playing games.

Across a series of genetically informative models, we found consistent, bidirectional causal influences from cognitive development at age 3 to cognitive stimulation at age 4, and from cognitive stimulation at age 3 to cognitive development at age 4. The prospective causal paths in both directions accounted for a third and up to half of the constructs’ phenotypic correlations. Our findings emphasize the active role that children play in constructing their learning experiences, and challenge the idea that children are passive recipients of environmental inputs.

Discussion

Twin studies can be used to strengthen causal inferences for observed associations between two constructs by controlling for their shared genetic and environmental influences (McAdams et al., 2021). Specifically, twin studies can address whether associations between a putatively environmental exposure and developmental differences in a phenotype remain significant after accounting for the confounding effects of shared etiology (i.e., common causes; McAdams et al., 2021). Recent years have seen an explosion of novel modelling approaches that extend the classical twin design, which enable causal inferences but are yet to be systematically applied in psychological research (Eberli et al., 2019; McAdams et al., 2021). Here, we fitted direction-of-causality (DoC) models (Heath, 1993), Mendelian Randomization (MR) extensions of the DoC model (Minică et al., 2018), and cross-lagged twin models (Burt et al., 2005) to investigate if children’s cognitive stimulation causes their cognitive development or vice versa at age 3 and 4 years.

We found prospective causal associations between children’s cognitive development and their cognitive stimulation that were bidirectional. Thus, contemporaneous mechanisms drive the causal influences between cognitive ability and stimulation: Children benefit from experiencing cognitively stimulating environments, and at the same time their cognitive development evokes the cognitive stimulation that their parents provide. Our findings align with a growing body of evidence documenting that children are not passive recipients of environmental inputs but select, modify, and create experiences that are correlated with their genetic proclivities (Bronfenbrenner & Morris, 2006; Wertz et al., 2019).

The prospective, bidirectional causal influences between cognitive development and cognitive stimulation were significant, accounting for between a third to nearly half of their phenotypic correlations across time. Thus, a substantial proportion of the phenotypic associations between cognitive development and cognitive stimulation can be attributed to bidirectional causal effects, while shared etiology or common causes – in particular, the shared environment – accounted for the remainder of the correlations. Finding that common causes and bidirectional causal effects jointly explain the associations between cognitive development and cognitive stimulation is key for developing realistic expectations for the magnitude of the effects that early-life interventions can possibly achieve (von Stumm, 2022).

We also showed that children’s differences in cognitive development and stimulation are largely due to shared environmental influences (56%-74%), followed by additive genetic influences (24%-40%). A similar pattern emerged for the etiologies of the associations between cognitive development and stimulation, which were again mainly due to shared environmental (76%-83%) and then additive genetic influences (16%-20%). Non-shared environmental influences on cognitive development and cognitive stimulation were negligible. While this study is to our knowledge the first to estimate the heritability of cognitive stimulation and its association with cognitive development, our findings confirm that all traits are heritable, including putatively environmental measures that are genetically influenced (Krapohl et al., 2017; Plomin, 1995; Polderman et al., 2015).


Limitations

Notwithstanding this study’s many strengths, including the analysis of twin and genomic data, large sample sizes, and repeated assessments of the core constructs using state-of-the-art methods, it is not without limitations. First, cognitive stimulation was assessed using seven parent-reported items, but a multi-informant approach (i.e., naturalistic home observations) with a greater number of observed variables would have improved the measures’ validity. Second, data on cognitive stimulation were only collected at the twins ages 3 and 4 years, which made it impossible to test for meaningful changes in the direction of causality over the longer course of childhood. Third, the association between the PGS for years spent in education (Lee et al., 2018) and cognitive development was small, which is indicative of weak instrument biases that can lead to overestimation of causal effects (Burgess & Thompson, 2011). In addition, cognitive development and cognitive stimulation did not have a sufficiently differentiated genetic architecture to meet the assumptions of DoC models (Health, 1993; van Bergen et al., 2018). As a result, our preregistered analysis strategy was not viable, and we fitted cross-lagged twin models instead that require longitudinal data.


On average, people tend to overstate the improvement in their well-being over time and to understate their past happiness

Feeling Good Is Feeling Better. Alberto Prati and Claudia Senik. Psychological Science, Oct 7 2022. https://doi.org/10.1177/09567976221096158


Abstract: Can people remember their past happiness? We analyzed data from four longitudinal surveys from the United States, France, the United Kingdom, and Germany spanning from the 1970s until the present, in which more than 60,000 adults were asked questions about their current and past life satisfaction. We uncovered systematic biases in recalled happiness: On average, people tended to overstate the improvement in their well-being over time and to understate their past happiness. But this aggregate figure hides a deep asymmetry: Whereas happy people recall the evolution of their life to be better than it was, unhappy ones tend to exaggerate their life’s negative evolution. It thus seems that feeling happy today implies feeling better than yesterday. This recall structure has implications for motivated memory and learning and could explain why happy people are more optimistic, perceive risks to be lower, and are more open to new experiences.


The Equality Paradox: Gender Equality Intensifies Male Advantages in Adolescent Subjective Well-Being

The Equality Paradox: Gender Equality Intensifies Male Advantages in Adolescent Subjective Well-Being. Jiesi Guo et al. Personality and Social Psychology Bulletin, October 7, 2022. https://doi.org/10.1177/01461672221125619

Abstract: Individuals’ subjective well-being (SWB) is an important marker of development and social progress. As psychological health issues often begin during adolescence, understanding the factors that enhance SWB among adolescents is critical to devising preventive interventions. However, little is known about how institutional contexts contribute to adolescent SWB. Using Programme for International Student Assessment (PISA) 2015 and 2018 data from 78 countries (N = 941,475), we find that gender gaps in adolescents’ SWB (life satisfaction, positive and negative affect) are larger in more gender-equal countries. Results paradoxically indicated that gender equality enhances boys’ but not girls’ SWB, suggesting that greater gender equality may facilitate social comparisons across genders. This may lead to an increased awareness of discrimination against females and consequently lower girls’ SWB, diluting the overall benefits of gender equality. These findings underscore the need for researchers and policy-makers to better understand macro-level factors, beyond objective gender equality, that support girls’ SWB.


Social salience of self-control (tight) vs-self-indulgence (loose) orientations, English books, XX century: The trend of self-control displays a steady increase throughout, self-indulgence increases from the late 70s-early 80s

The self-control vs. self-indulgence dilemma: A culturomic analysis of 20th century trends. Alberto Acerbi, Pier Luigi Sacco. Journal of Behavioral and Experimental Economics, October 6 2022, 101946. https://doi.org/10.1016/j.socec.2022.101946

Highlights

• We study the long-term dynamics of self-control vs. self-indulgence

• We adopt a culturomic approach analyzing the Google Books English corpus

• Self-indulgence shows a trend reversal around the 80s

• The analysis clearly tracks the onset of the consumerist revolution

• Our results are robust to choice of high-frequency words

Abstract: Within the conceptual framework of the Tightness-Looseness paradigm, we study the dynamics of the social salience of self-control (tight) vs-self-indulgence (loose) orientations across the 20th century on the basis of the English Google Books corpus, by means of the construction of specific lexica of which we track their relative frequency. We find that whereas the trend of self-control displays a steady increase throughout, that of self-indulgence is U-shaped, so that following a decline along the most part of the century, starting from the late 70s-early 80s we observe a reversal of the trend that signals an increasing salience of self-indulgence. Such result seems to reflect the consumerist turn that has characterized the post-industrial cycle from the 80s onwards. The coexistence of growing trends for mutually antagonizing orientations calls for further analysis of their social interplay. We also perform a parallel analysis on semantically related lexica that confirm the robustness of our findings.
