The relationship between health and political ideology begins in childhood: Healthy children more likely to express conservative ideology as older adults, independent of personality, academics, and later-life heath

The relationship between health and political ideology begins in childhood. Viji Diane Kannan et al. SSM - Population Health, August 24 2022, 101214. https://doi.org/10.1016/j.ssmph.2022.101214

Highlights

• Healthy children more likely to express conservative ideology as older adults.

• Independent of personality, academics, and later-life heath.

• Association driven by children with better health.

• Childhood health may be mediating social forces to produce adult ideology.

Abstract: We investigate whether childhood health status influences adult political ideology and whether health at subsequent life-stages, adolescent personality traits, or adolescent academic aptitude mediate this relationship. Using a national longitudinal cohort sample, we found that better health among children under age 10 was positively related to conservative political ideology among adults over age 64. Children with excellent health compared to very poor health were 16 percentage points more likely to report having a conservative political ideology in adulthood. Children with excellent health compared to very poor health were 13 percentage points less likely to report having a liberal political ideology in adulthood. Adults who had excellent health as children were 30 percentage points more likely to report conservative ideology than liberal ideology. However, the difference in ideological position for adults who had very poor childhood health was negligible. That is, the health and ideology relationship is being driven by those who were healthier early in life, after controlling for family income and material wealth. No evidence was found for mediation by adolescent heath, adult heath, adolescent personality traits, or adolescent academic aptitude. The magnitude of the coefficient for childhood health was substantively and statistically equivalent across race and sex. We discuss the possibility that, instead of being mediated, childhood health may actually be a mediator bridging social, environmental, and policy contexts with political ideology. We also discuss the potential of social policy to influence health, which influences ideology (and voting participation), which eventually circles back to influence social policy. It is important to understand the nexus of political life and population health since disparities in voice and power can exacerbate health disparities.

4. Discussion

Political science research indicates that the impressionable formative years for political socialization begin early in life during childhood and that ideological expression can be influenced by childhood stimuli such as trauma, friendships, and new experiences. We show that one such early life contributor is health. We expand on recent evidence linking health to political partisanship. Party politics changes over time. We focused on ideology which more strongly relates to policy stances and political beliefs as well as conceptions of how the world operates and a variety of individual preferences (e.g., grammar, humor, art, room decorations) (Carney et al., 2008; Cichocka, Bilewicz, Jost, Marrouch, & Witkowska, 2016; Glasgow, Cartier, & Wilson, 1985; Jost, Nosek, & Gosling, 2008; Wilson, 1990; Wilson, Ausman, & Mathews, 1973). Ideology not only informs people's electoral choices, but how they conduct their lives.

We show that the relationship between health and ideology begins in childhood. And, our results provide no evidence that childhood health is mediated by health at subsequent life-stages. Adolescent and adult health have no relation to adult political ideology independent of childhood health. Childhood is, thus, a sensitive period for the relationship between health and ideology.

We also show that the relationship between health and ideology endures over nearly six decades, potentially influencing a lifetime of electoral decisions. Thus, the impact of local physical, social, and policy environments on childhood health could have lasting implications for the ideological composition of those local electorates.

We proposed that adolescent personality and academics could mediated the health and ideology relationship. However, our findings do not show statistically significant mediation of childhood health through these adolescent characteristics as a whole. Nonetheless, the Vigor and Maturity personality traits individually served as mediators, although in opposing directions. Vigor was related to conservative ideology while Maturity was related to liberal ideology. Another explanation for the lack of mediation might also be that suggested by behavioral genetics research, which has shown that rather than personality contributing to ideology, both ideology and personality derive from a common underlying heritable latent factor (Hatemi & Verhulst, 2015; Verhulst, Eaves, & Hatemi, 2012). Similarly, since health is heritable, researchers have proposed that health may also partly derive from genetic factors giving rise to personality and ideology (Pacheco & Fletcher, 2015).

Adults who had excellent childhood health were 30 percentage points more likely to identify with conservative ideology than to identify with liberal ideology. However, the difference in ideological position for adults who had very poor childhood health was negligible. That is, the health and ideology relationship is being driven by those who began life with an advantaged health position, even controlling for early life family income and material wealth. From very poor to excellent childhood health, the probability of adult conservative ideology monotonically increases and liberal ideology monotonically decreases.

These results occur in the context of a longitudinal cohort analysis. Project Talent participants were high schoolers in 1960. The age range was ten years. Most participants were very close in age, within a four-year range, with fewer students in the younger and older tails. Students hailed from small rural towns and big cities and differed in their economic, cultural, and social backgrounds (American Institutes for Research (AIR) (2016). This cohort witnessed the same national and cultural events during childhood, adolescence, and young adulthood — school desegregation, civil rights, labor rights, Medicare/Medicaid, two wars, various protests, various assassinations, etc. The distribution of health levels and the distribution of ideological positions likely differs for this generation compared to recent generations. At a minimum, other generations are expected to differ in intercept and slope. Thus, we acknowledge the specificity of our study's findings to the Baby Boomer generation. We encourage the use of data from other generations in future studies to elucidate the health and ideology relationship under different social, economic, and cultural conditions.

In addition to being from one cohort, our sample was between 63 and 74 years of age. One concern with a sample of older adults is that of growing conservatism with age. However, studies have shown that ideology tends to be stable across the life-span (Sears & Brown, 2013; Sears & Funk, 1999) and that persons aging beyond young adulthood and middle age have tended to become more liberal in many respects (Glenn, 1974). Americans of this age group express a mix of conservative and liberal positions regarding trust in government, trust in big business and markets, support for social programs, and support for marginalized groups (Desilver, 2014). However, larger percentages hold consistently liberal or consistently conservative views (Desilver, 2014). Our findings may not hold across the globe in countries where economic and social conservatism are uncorrelated or even negatively correlated. Studies using data from other countries would illuminate more of the health and ideology relationship under different ideological dynamics. Another consideration with this age group is that of mortality selection over the nearly six decades between PT60 and PTPS12. While mortality is likely higher among unhealthy participants, still the distribution of health levels in PTPS12 was not heavily skewed toward healthy participants and showed a general decline of health with age. Furthermore, frequencies at all levels of childhood and adolescent health are similar for the total PT60 sample and the PTPS12 sample.

Other limitations require consideration as well. Measurement of childhood health was retrospective, although made by adolescents only a few years older. Prior work suggests such reports are reliable, even taken at far later points in the lifespan (Haas, 2007). Our sample is largely white. Black and white Americans who were adolescents in the 1960s experienced their country and political power differently over the six decades captured in this longitudinal cohort study. However, we found that there was little substantive and no statistical difference between black participants, white participants, and the sample as a whole.

A major limitation is the lack of data over potentially important life stages during the lengthy period between high school and one's late 60s. While Project Talent follow-up surveys were conducted in the 1960s and 1970s, unfortunately, participants from those surveys have virtually no overlap with PTPS12. Thus, we are unable to conduct a detailed study of life-course paths or intervening experiences. This study is ideal, however, for examining links between a formative early period and later-life ideology. We are not aware of any other study analyzing the association between health and any political outcome over such a long time period. 

A meta-analytic review of the gender difference in leadership aspirations: Men exhibit higher aspirations than women; the effect size does not decrease with increasing year of study publication

A meta-analytic review of the gender difference in leadership aspirations. Ekaterina Netchaeva et al. Journal of Vocational Behavior, Volume 137, September 2022, 103744. https://doi.org/10.1016/j.jvb.2022.103744

Highlights

• We meta-analytically examine the gender difference in leadership aspirations.

• Findings reveal men exhibit higher aspirations than women.

• The size of this effect does not decrease with increasing year of publication.

• The gender difference is larger among working adults in male-dominated relative to female-dominated industries.

• The gender difference is larger among working adults and post-secondary students, relative to secondary students.

Abstract: Compared to their representation in the workforce, women are significantly underrepresented in leadership roles in the United States. Whereas substantial research attention has been paid to the role of bias and discrimination in perpetuating this gap, less has been devoted to exploring the gender difference in aspirations for these roles. We draw from social role theory to hypothesize that men have higher leadership aspirations than women and test our hypothesis using a meta-analysis of 174 U.S. published and unpublished samples (N = 138,557) spanning six decades. The results reveal that there is a small but significant gender difference in the predicted direction (Hedge's g = 0.22). Notably, the gender difference has not narrowed significantly over time, and appears to widen at college age and among working adults within male-dominated industries. Our results also suggest that the process and dissemination of research in this domain exhibits bias. We discuss the implications of our conclusions for future research.

For 31.2% of the music plays, people did not recognize highly salient animal voices (regarding the type of acoustic source as well as the frequency spectra) when executing a counting task

The unnoticed zoo: Inattentional deafness to animal sounds in music. Sandra Utz, Friedericke Knauss & Claus-Christian Carbon. Attention, Perception, & Psychophysics, Aug 25 2022. https://rd.springer.com/article/10.3758/s13414-022-02553-9

Abstract: Inattentional unawareness potentially occurs in several different sensory domains but is mainly described in visual paradigms (“inattentional blindness”; e.g., Simons & Chabris, 1999, Perception, 28, 1059–1074). Dalton and Fraenkel (2012, Cognition, 124, 367–372) were introducing “inattentional deafness” by showing that participants missed by 70% a voice repeatedly saying “I’m a Gorilla” when focusing on a primary conversation. The present study expanded this finding from the acoustic domain in a multifaceted way: First, we extended the validity perspective by using 10 acoustic samples—specifically, excerpts of popular musical pieces from different music genres. Second, we used as the secondary acoustic signal animal sounds. Those sounds originate from a completely different acoustic domain and are therefore highly distinctive from the primary sound. Participants’ task was to count different musical features. Results (N = 37 participants) showed that the frequency of missed animal sounds was higher in participants with higher attentional focus and motivation. Additionally, attentional focus, perceptual load, and feature similarity/saliency were analyzed and did not have an influence on detecting or missing animal sounds. We could demonstrate that for 31.2% of the music plays, people did not recognize highly salient animal voices (regarding the type of acoustic source as well as the frequency spectra) when executing the primary (counting) task. This uncovered, significant effect supports the idea that inattentional deafness is even available when the unattended acoustic stimuli are highly salient.

Discussion

Inattentional deafness was firstly shown by Dalton and Fraenkel (2012) were participants missed by 70% a voice repeatedly saying “I’m a Gorilla” when they were focusing on a primary conversation. In the present study, not only the validity perspective was extended by using ten excerpts of popular musical pieces from different music genres, but also acoustic signals highly distinctive from the primary sound (i.e., animal sounds) were presented. Including sounds created by nonhumans into music is not only used as artificial stimuli in experimental studies but also in experimental music—the so-called biomusic. Some famous examples are the symphonic poem “Pini di Roma,” by Respighi first performed in 1924, where a recording of a real nightingale was included in the orchestra performance, or Pink Floyd using howling and barking dogs in their songs “Seamus” (1971) and “Dogs” (1976).

Results of the present study using those biomusic elements revealed a successful transfer of the results by Simons and Chabris (1999) and by Dalton and Fraenkel (2012) to the auditory domain of musical processing. Many of the clearly audible, very salient “auditory Gorillas” with no connection to music (in contrast to Koreimann et al., 2014) passed unnoticed by participants listening to musical pieces while being occupied with an attention-consuming counting task.Footnote3 Importantly, this finding based on a paradigm where the primary and secondary auditory signal was very different as they stemmed from different domains (primary signal was a piece of familiar music, the secondary signal was an animal sound) essentially extends the preliminary finding of Koreimann et al. (2014) where the domain was not different between both signals.

Attentional focus

Regression analyses showed that only the objective measure of deviation from the correct number in the counting task seems to be a significant predictor of inattentional deafness. A higher deviation from the correct answer in the counting task led to a higher likeliness to perceive the animal sounds. Therefore, more counting errors on the task led to a lower susceptibility for inattentional deafness. It could therefore be assumed that inattentional deafness is due to a lack of directing the entire attentional focus on the task. It might be that those participants with more errors generally focus less on the primary counting task and have more cognitive resources available to detect the animal sound in the first place. Another explanation might be that errors are a consequence of detecting the animal sound, diverting the attention from the primary task to the sound, and as a result, losing the count. These results are not only consistent with inattentional blindness/deafness literature (e.g., Wayand et al., 2005), but are also in accordance with findings on change deafness (see, e.g., Neuhoff, & Bochtler, 2018; tendentially in Vitevitch, 2003). However, Koreimann et al. (2014) did not find significant differences in the primary task between detecting and not detecting the unusual event. Also, the performance in the study by Vitevitch (2003) was only tendentially slower for those who detected the voice change. Future research has to look closer to the precise parameters of attentional focus on different cognitive processing levels responsible for inattentional deafness.

Perceptual load

The frequency of inattentional deafness could not be explained by the variation of perceptual load in this study. Higher perceptual load did not induce a higher susceptibility for inattentional deafness. Considering the participants’ mean ratings of task difficulty (see Table 3), this might partially be due to the fact that tasks were generally perceived as very demanding. The mean task difficulty of 5.53 (on a rating scale ranging from 1 = very easy to 7 = very demanding) can be considered as very high, especially given the fact that the “easiest” task still received an average rating of 4.20. Therefore, the variance of task difficulty might have been too low and the tasks generally too difficult to be able to clearly differentiate high from low perceptual load.

Feature similarity and feature saliency

The absence of an effect of feature similarity on the frequency of inattentional deafness can at least partially be attributed to a slight distinction between the two groups. Since the main aim of the present study was to show inattentional deafness to a highly striking auditory stimulus in music, attention was primarily focused on transferring the findings of the visual domain into the auditory domain by using a similar paradigm as was used by Koreimann et al. (2014). Therefore, particular emphasis was put on fitting animal sounds to the musical pieces regarding low feature similarity in order to maximize the effect. The musical pieces with particular distinct low feature similarity were then sorted into the low feature similarity condition, and the rest was sorted into the high feature similarity condition. However, the high feature similarity condition was less distinct since the fit between musical pieces and animal sounds was far more heterogeneous. The small sample size of five musical pieces in each of the groups needs to be taken into account as well, especially with regard to heterogeneity within these relatively small groups. Therefore, interpretation of the differences between musical pieces concerning feature similarity should also be conducted on an individual basis. As can be seen in Table 3, the lowest rate of inattentional deafness was found in The Moldau, by Bedřich Smetana, and in Symphony No. 5, by Ludwig van Beethoven. Whereas feature similarity was high in the Symphony No. 5 (due to the task requiring to follow different instrumental voices in the piece which varied in pitch and were similar in pitch to the Gorilla) it was low in The Moldau (because the task required to pay attention to the violin which was consistently distant in absolute pitch from the roar of the lion that served as the unexpected animal sound). Yet the roar of the Lion and of the Gorilla was easily detected. A similar finding can be reported for the pieces with the highest percentage of inattentional deafness—Ain’t No Sunshine, by Tom Jones, and In the Hall of the Mountain King, by Edvard Grieg. Whereas the high howling of a Wolf and the low-frequency bass voice of the singer in Ain’t No Sunshine suggest a low feature similarity, the cymbals and the cock-a-doodle-doo in the Hall of the Mountain King were comparatively much closer in tone pitch and therefore had high feature similarity. Yet inattentional deafness had a high frequency in both pieces. Differences in feature similarity might not be sufficient to entirely explain why some musical pieces were comparatively much more prone to inattentional deafness than others. Another factor might be, that both the Lion and the Gorilla were often described as a growling sound. A growling animal can be considered as a warning sound. If a significantly lower rate of inattentional deafness could be demonstrated in those musical pieces containing an aggressive sounding animal, this would support the assumption made by Murphy et al. (2013) of the auditory modality having an early warning function which can be crucial for the detection of alarm sounds in the environment. Lastly, it should be taken into consideration that a musical piece is a very complex construct containing several different streams of musical voices. The overall complexity of the piece and the number of instruments or voices in a musical piece might have an impact and should be considered in future research regarding inattentional deafness in music.

In addition to the subjective descriptions, the feature saliency of animal sounds was further analyzed by looking at replicable psychoacoustical measures such as loudness, specific loudness, roughness, and impulsiveness. All manipulated music pieces with animal sounds were compared with the original pieces without animal sounds. All these measures were not able to predict the percentage of missed animal sounds.

General discussion

The results of this study demonstrate that inattentional deafness in the musical realm exists, even when a highly bizarre, noticeable auditory “Gorilla” appears twice during a known musical piece. Contrary to what had previously been shown by Simons and Chabris (1999) feature similarity or our additionally used concept of feature saliency could not predict the susceptibility to inattentional deafness. One explanation might be that our measures were not the most adequate ones to capture those effects of feature similarity or feature saliency. However, as we took great care of addressing subjective as well as established objective measures, this line of argument does not seem to be very probable. Another straightforward reason could be that as soon as a certain level of perceptual load (in our case: the counting tasks) occupies our resources, we are susceptible to inattentional deafness because our attentional resources are becoming too limited. So, we will only detect the auditory “Gorillas” if our attention strays from the primary task leaving enough cognitive resources available. Indeed, we were able to document an impact of attentional focus: Whereas the subjective rating of the ability to focus attention on the specific task by the participants themselves showed no effect, the objective measure of deviance from the counting task could be found to go along with a higher frequency of inattentional deafness. A conclusion of a cause–effect relationship could not be drawn from this result, however.

Although the overall mean frequency of inattentional deafness of 31.2% may seem relatively low in comparison to findings of other authors (e.g., 57% in Koreimann et al., 2014), the results are highly remarkable. It has to be taken into account that not only did inattentional deafness appear in all but two participants and had a frequency rate of 50% or more in ten participants, but it also appeared in musical pieces that were presented after an animal sound in a previous musical piece had already been detected! More than a third (36 out of 101) of the missed animal sounds was missed after the previous detection of a different animal sound. The effect of inattentional deafness was so strong that it even appeared after participants had the chance to develop first ideas regarding the aim of the conducted experiment and to build up an expectation of more animal sounds appearing in the following musical pieces.

Whereas most of the participants expressed genuine surprise when hearing the animal sounds, because they perceived the animal sounds as very salient, other participants reported that they blended in very well with the music and could possibly be mistaken for belonging to the musical piece. This finding confirmed the decision to exclude all unknown musical pieces from further analysis to ensure that the appearance of inattentional deafness was not only due to interpreting the animal sounds as belonging to the musical piece.

Overall, very conservative and strict criteria for actual misses were applied. Animal sounds were also not counted as missed if participants reported hearing the animal sound only once after first presentation of the musical piece for the possibility that this resulted from a lack of remembering how often the animal sound was noticed rather than from inattentional deafness in one of the two appearances of animal sounds within the musical pieces. Considering these limitations in classifying inattentional deafness, the rate of approximately 31.2% is all the more impressive. Not only did inattentional deafness occur in almost all participants and all musical pieces (with very diverse rates of courses), in some participants, the phenomenon also extended over several musical pieces. To the best of the authors’ knowledge, no other study has revealed repeated susceptibility to inattentional deafness before. The likeliness of the appearance of inattentional deafness was analyzed regarding differences between people and differences between characteristics of the musical pieces. Not all findings investigated in previous studies could be transferred to the domain of inattentional deafness in music. Yet the focus of the present study lay more on investigating a possible influence of previously unattended facets and generating new hypotheses for future studies. Due to the considerably high heterogeneity of the musical pieces as well as the respective animal sounds used in this study and the high overlapping of different variables, it cannot be ruled out that parameters other than the attended variables played an important role in the frequency of inattentional deafness. Future research should attempt to identify the underlying mechanisms and musical properties that are involved in inducing or constraining inattentional deafness going beyond concepts like conceptual load or feature similarity. Special focus should be directed on the question why some individuals are especially and even repeatedly prone to the phenomenon of inattentional deafness. Individuals’ ability to concentrate and narrow attention to one task as well as differences in motivation and the eagerness to succeed, should hereby be investigated further in order to precisely identify the underlying mechanisms.

Across 45 countries in 11 world regions, male and female faces rated as more attractive were rated as more confident, emotionally stable, intelligent, responsible, sociable, and trustworthy

Examining the “attractiveness halo effect” across cultures. Carlota Batres & Victor Shiramizu. Current Psychology, Aug 25 2022. https://rd.springer.com/article/10.1007/s12144-022-03575-0

Abstract: Research has found that attractiveness has a positive “halo effect”, where people tend to attribute socially desirable personality traits to physically attractive individuals. Several studies have documented this “attractiveness halo effect”, with most research using western samples. This study sought to examine the “attractiveness halo effect” across 45 countries in 11 world regions. Data was collected through the Psychological Science Accelerator and participants were asked to rate 120 faces on one of several traits. Results showed that attractiveness correlated positively with most of the socially desirable personality traits. More specifically, across all 11 world regions, male and female faces rated as more attractive were rated as more confident, emotionally stable, intelligent, responsible, sociable, and trustworthy. These findings, thus, provide evidence that the “attractiveness halo effect” can be found cross-culturally.

Abstract: Disinformation has been regarded as a key threat to democracy. Yet, we know little about the effects of different modalities of disinformation, or the impact of disinformation disseminated through (inauthentic) social media accounts of ordinary citizens. To test the effects of different forms of disinformation and their embedding, we conducted an experimental study in the Netherlands (N = 1,244). In this experiment, we investigated the effects of disinformation (contrasted to both similar and dissimilar authentic political speeches), the role of modality (textual manipulation versus a deepfake), and the disinformation’s embedding on social media (absent, endorsed or discredited by an (in)authentic citizen). Our main findings indicate that deepfakes are less credible than authentic news on the same topic. Deepfakes are not more persuasive than textual disinformation. Although we did find that disinformation has effects on the perceived credibility and source evaluations of people who tend to agree with the stance of the disinformation’s arguments, our findings suggest that the strong societal concerns on deepfakes’ destabilizing impact on democracy are not completely justified.

Keywords: deepfakes, disinformation, endorsement, misinformation

Discussion

Although previous research has experimentally tested the impact of political deepfakes (Dobber et al., 2020; Vaccari & Chadwick, 2020), important questions remain: Do deepfakes in the political realm have a persuasive advantage over textual modes of deception, and are its effects contingent upon the endorsement by (fake) social media accounts in a “participatory” disinformation order (Lukito et al., 2020; Starbird, 2019)? Our main findings indicate that disinformation was rated as substantially less credible than an unrelated authentic speech. However, disinformation was not rated as substantially less credible than malinformation based on an authentic speech of the depicted political actor. Finally, exposure to a deepfake did not yield stronger effects than exposure to textual disinformation.

These findings contradict the ubiquitous concerns on deepfakes in the current digital information age and are not in line with literature on the persuasiveness of multimodal framing (Powell et al., 2018) or deepfakes (Lee & Shin, 2021). To some extent, the lack of effects is in line with previous research on deepfakes indicating that deepfakes do not directly mislead news users (Dobber et al., 2020; Vaccari & Chadwick, 2020). Rather, deepfakes may have a more indirect effect by making recipients unsure on what or whom to believe, which, in turn, reduces people’s trust in (online) news (Vaccari & Chadwick, 2020).

Regarding the embedding of disinformation on social media, we found that discrediting the fabricated statements can make disinformation appear more credible. The social endorsement cue does not have this effect. However, endorsing a disinformation message on social media resulted in a more positive evaluation of the depicted politician compared to the absence of such an endorsement. This can be understood as an in-group serving bias: The presence of a source cue similar to the recipient may enhance credibility. These findings show that disinformation agents employing trolls or bots that use inauthentic social media profiles are only effective in increasing the message’s credibility when a fake message is discredited. The democratic implications of these findings are optimistic: Deepfakes, at least based on the current state-of-the-art, do not seem to be as dangerous for society as assumed (Paris & Donovan, 2020). While concerns about information pollution and eroding public trust remain, deepfakes’ ability to destabilize democracy should not be overstated.

We did find some support for the conditional effects of deepfakes and textual disinformation. Overall, disinformation is more effective in affecting the credibility ratings and positive evaluations of the depicted politician among news users already inclined to support the attitudinal stance of disinformation’s statements—which is in line with extant research on the indirect impact of disinformation campaigns (e.g., Schaewitz et al., 2020). We can understand this as a confirmation bias (e.g., Knobloch-Westerwick et al., 2017): Disinformation that is congruent with people’s prior beliefs may reinforce these existing beliefs. Yet, we did not find support for a moderating role of prior levels of issue agreement on disinformation’s impact on message congruent beliefs. We can explain this as a ceiling effect: People already inclined to support the attitudinal stance of disinformation are not further bolstering their beliefs based on one single message that reassures the attitudes they already hold.

Despite contributing to our understanding of the political consequences of exposure to socially endorsed deepfakes, this article has a number of limitations. As the deepfake was almost as credible as an authentic decontextualized video (malinformation), we believe that the lack of effects was not only due to technological failures of the deepfake itself but also the lack of plausibility of the extremist political statements associated with the more moderate political actor. Yet, we aimed to strike a balance between actually voiced statements by the political actor and a delegitimizing narrative that would harm the political actor by making him look bad. To achieve this, some deviation from the truth and familiar statements was needed. The finding that people do not clearly differentiate between fabricated disinformation and decontextualized malinformation is an important finding in its own right: In times when the truth has become more relative (e.g., Van Aelst et al., 2017), people may also distrust authentic information when it triggers suspicion due to its unusual nature.

This specific trade-off between audiovisual credibility and argumentative discrepancies needs to be teased out further in the future: How far can a deepfake deviate from a political actor’s profile to still be perceived as credible, and what persuasive techniques can be used to make inauthentic arguments seem real? Hence, future research may experiment with different conditions that are more or less plausible and more or less distant to the everyday communication of a known target. They may also more centrally take into account people’s existing knowledge and beliefs related to the depicted politician’s issue positions. If deepfakes are no longer credible when they deviate too much from reality, this may have positive implications for democracy: There are limits to the “fake reality” shown in synthetic videos, and deepfakes are not capable of making everyone say anything while remaining credible.

We should also note that the construct of perceived credibility we used may mean different things for different participants. While some may interpret the statements as referring to the authenticity of the presented materials, others may see it as the “truth value” of the statements themselves (Lewandowsky, 2021). Against this backdrop, some participants may find a deepfake uncredible because the statements do not have truth value, whereas others detect deception in the presentation of the video. Although robustness checks distinguishing between these drivers of credibility do not point to substantial differences, we suggest future research to rely on a more comprehensive multidimensional measure of credibility that distinguishes between these interpretations. In addition, although exposure to one short deepfake on its own may not affect polarization or political evaluations, the cumulative (targeted or algorithmic) exposure to attitude-consistent disinformation may, over time, exert a stronger influence on people’s beliefs and behaviors. Finally, future research may also need to take individual-level differences into account that could predict susceptibility and resilience to disinformation, such as people’s trust in social versus mainstream media, and formats more likely to contain disinformation.

As a key take-away point, we stress that although the disrupting impact of deepfakes on democracy should not be overstated, deepfakes’ ability to become part of native online political discussions may offer a persuasive advantage when it can find nuanced ways to delegitimize political actors or amplify the political beliefs of targeted groups in society via social media.

We review the evidence linking gender to dishonesty and conclude that men are often more dishonest than women, especially in competitive settings where lies advance self-interest

Gender Similarities and Differences in Dishonesty. Jessica A. Kennedy, Laura J. Kray. Current Opinion in Psychology, August 24 2022, 101461. https://doi.org/10.1016/j.copsyc.2022.101461

Abstract: We review the evidence linking gender to dishonesty and conclude that men are often more dishonest than women, especially in competitive settings where lies advance self-interest. However, gender differences in dishonesty are often small and mutable across situations. We propose that attending to self-regulatory constructs such as moral identity might help researchers move beyond the evolutionary-cultural debates over the origin of gender differences toward identifying factors that promote honesty from both genders.

Abstract: New technology invariably provokes concerns over potential societal impacts. Even as risks often fail to materialize, the fear continues. The current research explored the psychological underpinnings of this pattern. Across four studies (N = 2,454 adults recruited via Amazon Mechanical Turk), we found evidence for the role of status quo thinking in evaluating technology. In Study 1, we experimentally manipulated the reported age of unfamiliar technology and found that people evaluate it more favorably when it is described as originating before (vs. after) their birth. In Studies 2 through 4, participants’ age at the time of invention strongly predicts attitudes toward a wide range of real-world technologies. Finally, we found that individual differences in status-quo-based decision-making moderated evaluations of technology. These studies provide insight into how people respond to the rapidly changing technological landscape.

Contrary to findings from previous correlational studies, we do not find any significant impact of social media usage as it was defined in our study on well-being and academic success

Effects of restricting social media usage on wellbeing and performance: A randomized control trial among students. Avinash Collis, Felix Eggers. PLoS, August 24, 2022. https://doi.org/10.1371/journal.pone.0272416

Abstract: Recent research has shown that social media services create large consumer surplus. Despite their positive impact on economic welfare, concerns are raised about the negative association between social media usage and well-being or performance. However, causal empirical evidence is still scarce. To address this research gap, we conduct a randomized controlled trial among students in which we track participants’ daily digital activities over the course of three quarters of an academic year. In the experiment, we randomly allocate half of the sample to a treatment condition in which social media usage (Facebook, Instagram, and Snapchat) is restricted to a maximum of 10 minutes per day. We find that participants in the treatment group substitute social media for instant messaging and do not decrease their total time spent on digital devices. Contrary to findings from previous correlational studies, we do not find any significant impact of social media usage as it was defined in our study on well-being and academic success. Our results also suggest that antitrust authorities should consider instant messaging and social media services as direct competitors before approving acquisitions.

Discussion

In this paper, we analyzed the effects of restricting social media usage. We did not find significant causal effects of social media usage on well-being or academic performance, other than students attempting (but not succeeding) to pass more courses or courses with more credits. However, we found robust evidence of substitution effects that can potentially explain the null finding. Specifically, we showed that social media and instant messaging apps can be substitutes. The European Commission approved Facebook’s acquisition of WhatsApp in 2014 based on Facebook’s claim that it operates in a different market and does not compete directly with WhatsApp [52]. Our results indicate that they are in fact direct competitors. After acquiring WhatsApp, Facebook started automatically matching its users’ profiles with their WhatsApp accounts and has started integrating WhatsApp, Instagram and Facebook user accounts [53]. The European Commission fined Facebook €110 million in 2017 for this practice because Facebook had provided misleading information about the feasibility of automatically matching profiles during its acquisition of WhatsApp. However while announcing this fine, the Commission still maintained its belief that Facebook and WhatsApp do not directly compete with each other [54]. Antitrust authorities should consider the market power of this combined entity if the world’s biggest social media platforms are integrated with the world’s biggest instant messaging platform. This finding also raises the question how to properly define social networks, for future academic studies or antitrust cases.

While we found null results estimating the causal impact of social media usage on well-being and academic performance, and not all null results matter, we believe that null results are interesting and important in this context. The media has hyped correlational studies showing a negative association between social media usage and well-being and it is important to balance this narrative through causal evidence. A limitation of our study is the lack of a larger sample size to detect smaller effects. While these small effects might not be economically significant, more research is needed using massive samples. Future research can also look at differences between Android and iOS users in more detail with larger samples since we lack power to analyze these differences in our current study. However, it is challenging to recruit a large number of subjects from a representative sample for a long-term study. Direct collaborations with social media platforms or internet service providers (which control internet traffic) could be a way of obtaining data from larger samples. These would also facilitate more targeted interventions such as restricting only content consumption or social interactions on social media [18].

It is interesting to notice that while social media generates large amount of consumer surplus [3], it doesn’t seem to affect the subjective well-being of users. Future research can explore this wedge between consumer surplus and subjective well-being and see whether they are correlated for some products and uncorrelated for others. Future research should also explore the addictiveness of social media in more detail [55]. Our findings in block 3 show that the students in the treatment condition go back to their old habits and do not adopt a lower social media usage that they experienced in block 2. On the other hand, showing students how much time they are spending on social networks via the software seems to have an overall negative trend on its usage (comparing usage in block 1 and block 3). Curing social media addiction (if it is indeed addiction) might therefore be a longer process. Future research can look at mechanisms for the emergence of social media addiction, for e.g. through targeted advertising or news feed algorithms and features of social media apps (e.g. video sharing) which are correlated with addiction.

Moreover, due to our student sample implications for the general population are limited. It could be that students use social media mostly for communication purposes and therefore show significant substitution effects with instant messaging. We might see different effects for users who visit social media for content consumption, e.g., watching videos, instead of social interaction [18]. In this regard, newer social media services such as TikTok might have a different effect. However, these and other comparable social media services were not relevant at the time we conducted the study (as we measured in block 1). More research is needed looking at emerging social media platforms such as TikTok. Moreover, one could define social media more broadly to include instant messaging services and implement a stricter restriction involving all types of communication and social networking apps. However, conducting such a study for any length of time is a challenging endeavor.

Additionally, while we study the impact of social media on students and academic performance, future research can look at workplace settings and study the impact of social media and its substitutes on worker productivity and well-being. We believe that rigorous causal evidence through randomized controlled trials and objectively measured time spent is the way forward in addressing questions regarding the impact of technology on well-being.

The widespread adoption of most major technologies in the past such as radio, television, video games and computers was followed with unfounded fears about their impact on well-being. This story repeats again with social media. We find that social media usage does not cause lower well-being or poor academic performance. Rather, we demonstrate that students find other means of social networking using instant messaging when exogenously restricting their social media usage. To conclude: You can take social networking away from the students, but you cannot take students away from their social network.

No Evidence That Siblings’ Gender Affects Personality Across Nine Countries

No Evidence That Siblings’ Gender Affects Personality Across Nine Countries. Thomas Dudek et al. Psychological Science, August 23, 2022. https://doi.org/10.1177/09567976221094630

Abstract: Does growing up with a sister rather than a brother affect personality? In this article, we provide a comprehensive analysis of the effects of siblings’ gender on adults’ personality, using data from 85,887 people from 12 large representative surveys covering nine countries (United States, United Kingdom, The Netherlands, Germany, Switzerland, Australia, Mexico, China, and Indonesia). We investigated the personality traits of risk tolerance, trust, patience, locus of control, and the Big Five. We found no meaningful causal effects of the gender of the next younger sibling and no associations with the gender of the next older sibling. Given the high statistical power and consistent results in the overall sample and relevant subsamples, our results suggest that siblings’ gender does not systematically affect personality.

Keywords: personality, siblings, gender, open materials

Discussion

Overall, we conclude that siblings’ gender does not meaningfully affect personality. Although data came from only nine countries (with a predominance on Western countries), the consistently small associations challenge the notion that any type of universal, gendered sibship dynamics affects personality. This conclusion also aligns with recent findings suggesting that one’s ordinal position among siblings does not meaningfully affect personality (Botzet et al., 2021; Damian & Roberts, 2015b; Lejarraga et al., 2019; Rohrer et al., 2015, 2017). Of course, it is possible that the effects of siblings’ gender and birth-order position are even more subtle and thus not detectable even when very large samples are investigated. This interpretation would align with recent suggestions that environmental influences, just like genetic influences, may be driven by thousands of factors, each with very small effect sizes (von Stumm & d’Apice, 2022). However, taking findings from behavioral genetics into account, it seems like these environmental causes are more likely to be found outside of the family environment (Briley & Tucker-Drob, 2014; Vukasović & Bratko, 2015).

It is also possible that the proposed mechanisms of both social-learning and sibling-differentiation theory apply in varying degrees in different families, resulting in average effects that net out at zero but that may occasionally “show up” in individual studies as significant effects. However, this account does not provide the most parsimonious explanation for discrepancies between our study and the past literature on the topic. Given inconsistent methodologies and small sample sizes, it seems reasonable that at least some of the incoherence can be attributed to publication bias (Ioannidis, 2005), which can result in a “continuous stream of conflicting results” (Damian & Roberts, 2015a). Furthermore, both social learning and sibling differentiation suggest that the effects of siblings’ gender are mediated through siblings’ personality—but the link between gender and personality is only of medium strength in the first place, even when an index designed to maximize differences is used. Thus, large effects of sibling gender may be implausible to begin with.

Lastly, sibling gender may not affect the widely used broad personality measures that we investigated, but recent economic research suggests that it does affect important life outcomes. Findings suggest that brothers decrease women’s labor earnings and that this may be partly driven by increased traditional family attitudes (Brenøe, 2022; Cools & Patacchini, 2019; Rao & Chatterjee, 2018). Investigating the specific mechanisms behind this brother-earnings penalty—whether they are psychological, sociological, or economic in nature—seems a worthwhile research endeavor. Our findings suggest that personality differences do not play a major part in this story.

Sniffing of Body Odors and Individual Significance of Olfaction Are Associated with Sexual Desire: A Cross-Cultural Study in China, India, and the USA

Sniffing of Body Odors and Individual Significance of Olfaction Are Associated with Sexual Desire: A Cross-Cultural Study in China, India, and the USA. Zi-lin Li, Thomas Hummel & Lai-quan Zou. Archives of Sexual Behavior, Aug 23 2022. https://rd.springer.com/article/10.1007/s10508-022-02398-1

Abstract: Olfactory sensations contribute to sexual desire and sexual behavior. However, the degree to which individual importance of olfactory function and body odors relate to sexual desire is not known. This study was conducted to preliminarily examine these relationships among Chinese college students (N = 1903) via the Importance of Olfaction Questionnaire, the Body Odor Sniffing Questionnaire, and the Sexual Desire Inventory, which were used to measure subjective significance of olfaction, frequency of sniffing self or others, and sexual desire, respectively. Individuals who assigned higher importance to olfaction or engaged more in body odor sniffing showed stronger sexual desire. We further explored these associations in different cultures to determine whether cultural consistency existed. We conducted a second study to make cross-cultural comparisons between Indian (N = 313) and US (N = 249) populations. For both countries, a higher importance placed on olfaction and a higher prevalence of body odor sniffing were consistently associated with stronger sexual desire. In conclusion, our study confirmed that people who placed more value on olfactory function or engaged more in body odor sniffing showed stronger sexual desire. These correlations were consistent for both sexes and across different cultures, further indicating the importance of olfaction in sexuality.

A Meta-analysis of the Effects of Trigger Warnings, Content Warnings, and Content Notes: No effect on affective responses to negative material nor on educational outcomes

Bridgland, Victoria, Payton J. Jones, and Benjamin W. Bellet. 2022. “A Meta-analysis of the Effects of Trigger Warnings, Content Warnings, and Content Notes.” OSF Preprints. August 23. doi:10.31219/osf.io/qav9m

Abstract: Trigger warnings, content warnings, or content notes are alerts about upcoming content that may contain themes related to past negative experiences. Advocates claim that warnings help people to emotionally prepare for or completely avoid distressing material. Critics argue that warnings both contribute to a culture of avoidance at odds with evidence-based treatment practices and instill fear about upcoming content. Recently, a body of psychological research has begun to investigate these claims empirically. We present the results of a meta-analysis of all empirical studies on the effects of these warnings. Overall, we found that warnings have no effect on affective responses to negative material nor on educational outcomes (i.e., comprehension). However, warnings reliably increase anticipatory affect. Findings on avoidance were mixed, suggesting either that warnings have no effect on engagement with material, or that they increase engagement with negative material under specific circumstances. Limitations and implications for policy and therapeutic practice are discussed.
