Abstract: The term “digital native” entered popular and academic discourse in the early 1990s to characterize young people who, having grown up surrounded by digital technology, were said to be highly technologically skilled. The premise was mobilized to criticize education for not meeting the needs of young people, thereby needing radical transformation. Despite being repeatedly discredited by empirical research and scholarly argument, the idea of the digital native has been remarkably persistent. This chapter explores the myth of the digital native and its implications for higher education. It suggests that the myth’s persistence signals a need to better understand the role of technology in young people’s lives. The chapter conceptualizes technology “practices,” considers how young adults experience technology in their college and university education, and how their practices are shaped by childhood and adolescence. The chapter closes with some propositions for educators, institutions, and researchers.

Introduction
In the late 1990s and early 2000s the idea of the “digital native” emerged (Bennett, Maton, & Kervin, 2008). In essence, it was proposed that because young people had grown up surrounded by technology, they had developed sophisticated technology skills superior to the adults around them. This made them “tech savvy” in a way that those from older generations could never be. And because of this difference, young people were dissatisfied with and disengaged from an education system that persisted with oldfashioned approaches to teaching and learning. This argument was used as the basis for calls for revolutionary, transformational change across education systems.
Since then, scholarly critique and empirical research have debunked the notion of the digital native (see Bennett & Corrin, 2017). Critiques have continually called into question the crude characterization of all young people as both highly adept with and avidly interested in digital technologies across the various aspects of their lives as well as the assertions about the implications for education. Research evidence has revealed a much more complex situation. The ways in which young people make use of digital technologies for learning, leisure, socializing, and work are richly diverse and very much dependent on the various contexts in which they engage. These findings reveal that there are indeed young people who are highly engaged with digital technologies, who are using opportunities that technologies provide to create and connect in new ways, and who participate via these technologies in activities and causes that interest them. But not all young people choose to or have the resources available to them to do so. This makes the universality of the digital native label inaccurate and misleading [...]
So what are we to make of the persistence of the notion of digital natives, given the nowsubstantial body of considered scholarship that has discredited this notion? The idea has had widespread popular appeal, perhaps because is seems to be true, based on anecdotal evidence. [...]
Beyond the power of anecdote, however, there are a number of ways to interpret the emergence of and continued interest in the digital native. Generational differences have long been a source of concern in many societies. This is reflected by the labelling and characterization of generations such as the “baby boomers,” “Generation X,” and the “millennials” (e.g., Howe & Strauss, 2000). The idea of the digital native can be seen as a variation of this familiar theme that pits generations against each other and serves to highlight one of many ways in which young people in general are different to older generations. But these generational stereotypes seldom withstand closer scrutiny, and the digital native stereotype, like others, is ultimately unhelpful in genuinely understanding the needs and interests of young people.
Another possible explanation could be that the notion of the digital native reflects a more general concern about the pace of change in modern life, as well as disquiet about the role of technology in driving social change. Again, this concern is not new. The history and sociology of technology reveal long-held misgivings about the ways in which technology has changed the nature of work, civic engagement, and social interaction well before the twenty-first century. Suggestions that an increased rate of change is further risking our ability to adjust to new technologies may explain recent heightened concerns, but the phenomenon itself is not new. From this perspective, characterizing young people as digital natives aligns with the concerns of many older people that technology is driving rapid change to the ways of life with which they are familiar. Thus, the idea of the digital native may reflect the genuine ambivalence that many feel about the role of technology in their lives and, more broadly, its influence on society.
Questions, too, might be posed about the motivations of those advocating for the existence of digital natives. In the field of educational technology, the vested interests of commercial vendors have led to many exaggerated claims that technology can and will revolutionize education (Buckingham, 2013). Education, for its part, has evolved over time, but much too slowly for some technology advocates. Academic reputations are also built on claims that technology will drive pedagogical innovations that will, in turn, increase student engagement and boost learning outcomes. Sceptics have often been labelled as Luddites in debates where polarized positions, untestable claims, and competing ideologies have, at times, overshadowed the findings of research and scholarship that necessarily lags the introduction of the latest technology.
There is clearly further work needed to discover what is at the heart of the concerns about young people and technology. While this is beyond the scope of this chapter, knowing more about why these questions exist is surely important. At the same time, this uncertainty should not prevent seeking to know more about the role technology plays in young people’s lives and consider what that means for education. As noted, scholars and researchers have already begun this quest [...]
We argue that while the idea of the digital native has been shown to be, at best, misleading and unhelpful, its persistence in our discourse, particularly about education, signals there is something underlying it that warrants our attention. It continues to invite us to ask important questions about how young people can, do, and could use technology to enhance their learning. This, in turn, raises important questions about teaching and teachers, educational systems and administrations, and institutional provision of technology infrastructure and learning spaces. [...]
We further argue that this research would benefit from a conceptualization of technology use that is underpinned by the notion of practice. A practice perspective allows us to go beyond regarding digital technologies as tools designed for particular uses to focusing on the ways in which individuals and groups adopt and adapt technologies and embed them in socially-constructed activities. These are technology practices—a notion that captures a range of possibilities and allows for technologies to be adopted and integrated into existing practices, for technologies to shape and so alter existing practice, and for entirely new practices to emerge. In this conceptualization, technologies are never “value free,” but instead carry the values and assumptions of designers and providers. At the same time, it gives possibility for users to adapt or disrupt the intended design or use. [...]
The focus of enquiry then becomes understanding the perspectives and practices of those using technologies, with consideration of the various contexts in which those practices occur. In education, this kind of research uses naturalistic approaches to explore “what is actually taking place when a digital technology meets an educational setting” (Selwyn, 2010, p. 70) rather than studying “state of the art” innovations. Such research complements a well-established and continuing tradition of research into specific pedagogical applications of technology by seeking to understand the nature of technology experiences more broadly. Understanding how students experience technology in their formal education and across their other life contexts is key to understanding how technology might be most effectively integrated [...]
A practice perspective also invites a particular way of considering how technology could best be integrated into education and, specifically, what skills, knowledge, and dispositions young people might need to develop in relation to technology (Bennett, 2014). Contemporary conceptualizations of digital literacy have evolved significantly from their predecessors, for example, computer literacy, ICT literacy. There is growing recognition that to be digitally literate means much more than having the skills to operate technology. [...]

Effects of instructors’ attractiveness on student evaluations of their teaching: Female instructors rated as more attractive receive higher instructional ratings; effect not found in the online environment
Babin, J. Jobu and Hussey, Andrew J. and Nikolsko-Rzhevskyy, Alex and Taylor, David, Beauty Premiums Among Academics (April 23, 2019). SSRN https://ssrn.com/abstract=3376925
Abstract: This paper examines the effects of instructors’ attractiveness on student evaluations of their teaching. We build on previous studies by holding both observed and unobserved characteristics of the instructor and classes constant, capitalizing on a unique panel dataset of instructor evaluations. Our identification strategy exploits the fact that the same faculty, in addition to traditional teaching in the classroom, often also teach in the online environment, where attractiveness is either unknown or less salient. We utilize multiple attractiveness measures, including facial symmetry software, subjective evaluations, and a novel, proxy methodology that resembles a “Keynesian Beauty Contest.” We identify a substantial beauty premium in face-to-face classes for women but not for men. While gender on its own does not impact teaching evaluation scores, female instructors rated as more attractive receive higher instructional ratings. This result holds across several beauty measures, given a multitude of controls and while controlling for unobserved instructor characteristics and skills. Notably, the positive relationship between beauty and teaching effectiveness is not found in the online environment, suggesting the observed premium may be due to taste-based discrimination.

Progressive Policy Institute: 21st century school systems, founded upon the four pillars of school autonomy, accountability for performance, diversity of school designs, and parental choice
Do-Something Congress No. 10: Fighting Inequality by Reinventing America's Schools. David Osborne, Emily Langhorne, Associate Director. Progressive Policy Institute, May 15 2019. https://www.progressivepolicy.org/projects/reinventing-americas-schools/do-something-congress-no-10-fighting-inequality-by-reinventing-americas-schools/
Progressives are rightly concerned about inequality, but some overlook the crucial role that underperforming public schools play in perpetuating poverty and inequality in America. The poor quality of many school systems is a serious impediment to social mobility for children from low-income and minority families, who can’t easily pick up and move to communities with good schools. The number of students taking college remediation classes has soared, and too many students graduate high school underprepared to enter either college or the workforce.
First-rate schools are key to delivering on America’s core promise of equal opportunity. That’s true for U.S. students everywhere – not just for kids trapped in poor schools in poor communities. In international comparisons, even students from America’s best suburban school districts consistently score below students from other advanced countries in Asia and Europe.
America’s public education system was designed for the Industrial Era. The centralized, bureaucratic approach that we inherited from the 20th century no longer works for the majority of America’s students. We need a new model, and fortunately one is emerging from cities that have embraced profound systems change, including New Orleans, Denver, Washington, D.C., and Camden, N.J. All have experienced rapidly improving student outcomes as a result.
These four cities are building 21st century school systems, founded upon the four pillars of school autonomy, accountability for performance, diversity of school designs, and parental choice. Essentially, 21st century school systems treat many of their public schools like charter schools, even if they call them “innovation schools,” “partnership schools,” or “Renaissance schools.”
Although transforming our K-12 education system to meet the needs of the modern era is primarily the responsible of state and local governments, Washington can play an important catalytic role by creating incentives for change. In particular, Congress can create and for districts that create autonomous schools, hold schools accountable for performance, and replace failing schools.

We found that social media use is not, in and of itself, a strong predictor of life satisfaction across the adolescent population: Social media effects are nuanced, small at best, reciprocal over time, gender specific
Social media’s enduring effect on adolescent life satisfaction. Amy Orben, Tobias Dienlin, and Andrew K. Przybylski. Proceedings of the National Academy of Sciences, May 6, 2019. https://doi.org/10.1073/pnas.1902058116
Abstract: In this study, we used large-scale representative panel data to disentangle the between-person and within-person relations linking adolescent social media use and well-being. We found that social media use is not, in and of itself, a strong predictor of life satisfaction across the adolescent population. Instead, social media effects are nuanced, small at best, reciprocal over time, gender specific, and contingent on analytic methods.

Fewer men (39.1%) than women (80.3%) reported removing some of their pubic hair; the practice was associated with age, sexual activity, relationship status, & partner’s PHR practice & expectations
“To Shave or Not to Shave”: Pubic Hair Removal and Its Association with Relational and Sexual Satisfaction in Women and Men. Paul Enzlin et al. The Journal of Sexual Medicine, May 15 2019. https://doi.org/10.1016/j.jsxm.2019.04.005
Abstract
Background: Pubic hair removal (PHR) is a widespread practice that entails certain health risks; however, there remains a lack of scientific information on the prevalence and antecedents of PHR, as well as on its association with sexual behavior and relational satisfaction.
Aims: To explore women’s and men’s attitudes regarding PHR and their PHR practices and the associations with demographic, relational, and sexual characteristics.
Methods: A total of 2,687 men and 1,735 women living in Flanders (the Northern part of Belgium) completed an online survey. Participants ranged in age from 15 to 60+ years; they self-identified as heterosexual, bisexual, or homosexual and reported various relationship statuses.
Main Outcome Measures: Demographic items (ie, age, religion, partner relationship status), sexuality-related items (ie, sexual activity, sexual orientation, age at first intercourse, number of sexual partners), PHR items (ie, reasons, inclination to have or not have sex after PHR, perceived partner preferences, partner’s PHR), and relationship satisfaction, assessed with the Maudsley Marital Questionnaire.
Results: Fewer men (39.1%) than women (80.3%) reported (partially) removing their pubic hair. In both men and women, the practice was associated with age, sexual activity, relationship status, and partner’s PHR practice and expectations. In men, sexual and relationship satisfaction were correlated with their partner’s PHR practices and whether these were in line with the men’s expectations. In women, sexual and relationship satisfaction were mostly correlated with whether both partner’s expectations were met. Although both men and women reported that the reasons for PHR were related to their sexual experiences and to their partner’s preference, only women reported that PHR was a way to enhance feelings of femininity. Finally, the reasons for not engaging in PHR were related to partner preferences and side effects.
Conclusion: PHR is a widespread practice and seems strongly associated with personal, partner-related, sexual, and relational factors. Strategies to prevent men and women from being confronted with health risks should take all these factors into account.

Could this be useful to design strategies for humans? Voluntary wheel running reduces weight gain in mice by decreasing high-fat food consumption
Voluntary wheel running reduces weight gain in mice by decreasing high-fat food consumption. Joshua Cordeira, Daniel Monahan. Physiology & Behavior, Volume 207, 1 August 2019, Pages 1-6. https://doi.org/10.1016/j.physbeh.2019.04.019
Highlights
• Wheel running for 30 min on 5 days per week reduced weight gain and adiposity
• Wheel running decreased energy intake from high-fat food, but not standard chow
• Pair-feeding reduced weight gain and adiposity to the same extent as wheel running
Abstract: We investigated whether wheel running for just 30 min on 5 days each week, an exercise routine based on recommended levels of physical activity for adults, regulates body weight and food intake in mice. Male C57BL/6 mice were divided into groups and given ad libitum access to high-fat food and standard chow or standard chow only. For 30 min on 5 days each week, mice were treated with an in-cage running wheel which was either open to allow voluntary exercise or locked and could not rotate for control. Wheel running reduced weight gain and fat mass among mice fed high-fat food and standard chow, but not mice fed standard chow only. Wheel running decreased high-fat food consumption. Standard chow intake was unchanged. Mice provided with a locked running wheel but pair-fed the same amount of food as wheel running mice also displayed reduced weight gain and fat mass. We conclude that voluntary wheel running for 30 min on 5 days each week reduced weight gain and fat mass in mice by preferentially decreasing high-fat food intake. This model of voluntary wheel running can be used to investigate mechanisms underlying the benefits of exercise on body weight and food intake, informing obesity intervention strategies for humans.

Unfragranced body odours of real partners are judged more similar than fake couples; no such difference for fragranced body odour; hormonal contraceptives may influence initial odour-mediated assortment
Evidence for odour-mediated assortative mating in humans: The impact of hormonal contraception and artificial fragrances. CarolineAllen et al. Physiology & Behavior, May 15 2019. https://doi.org/10.1016/j.physbeh.2019.05.002
Highlights
• Unfragranced body odours of real partners are judged more similar than fake couples.
• There was no such difference for fragranced body odour samples.
• Hormonal contraceptives may influence initial odour-mediated assortment.
• There was a sex difference in favourability of odour similarity within couples.
• Similarity ratings correlated with some verbal labels described by perfumers.
Abstract
There is substantial evidence for assortative partner preferences in humans based on physical characteristics. In contrast, evidence suggests that olfactory preferences tend to be disassortative, with people preferring body odour of potential partners who are dissimilar at key genetic loci, perhaps to gain fitness advantage through offspring heterozygosity. We compared ratings of perceived body odour similarity of real couples with those of randomly paired ‘fake’ couples. Contrary to prediction, we find that odours of real partners are perceived more, rather than less, similar to each other than fake couples. However, this applied only to natural odour samples: there were no differences in similarity levels of real and fake couples' samples which were collected while wearing artificial fragrances. Furthermore, in light of suggestions that hormonal contraception (HC) disrupts disassortative odour preferences in women, we compared odour similarity among real couples in which the female partner was using or not using HC at the time when the relationship began. We find that odours of HC-using couples are of intermediate similarity between non-using and fake couples, suggesting that HC use during partner choice could affect odour-influenced assortment. We also examined the association between relationship satisfaction and perceived similarity of unfragranced odours of real couples. We found that these are positively correlated in male partners but negatively correlated in the female partners, indicative of a sex difference in the relative favourability of odour similarity in partner preference. Finally, by comparing odour similarity ratings with those given by perfumers using a novel olfactory lexicon we found evidence that similarity judgements were based on the Spicy/Animalic aspects of individual odour profiles. Taken together, our results challenge the conventional view that odour-mediated partner preferences in humans are typically disassortative.

Many studies of animal culture overlook the possibility of individuals being able to develop behavioral forms without requiring social learning (naïve chimpanzees were provided the materials for wild pestle pounding behavior)
Individual acquisition of “stick pounding” behavior by naïve chimpanzees. Elisa Bandini, Claudio Tennie. American Journal of Primatology, May 13 2019. https://doi.org/10.1002/ajp.22987
Abstract: Many studies investigating culture in nonhuman animals tend to focus on the inferred need of social learning mechanisms that transmit the form of a behavior to explain the population differences observed in wild animal behavioral repertoires. This research focus often results in studies overlooking the possibility of individuals being able to develop behavioral forms without requiring social learning. The disregard of individual learning abilities is most clearly observed in the nonhuman great ape literature, where there is a persistent claim that chimpanzee behaviors, in particular, require various forms of social learning mechanisms. These special social learning abilities have been argued to explain the acquisition of the relatively large behavioral repertoires observed across chimpanzee populations. However, current evidence suggests that although low‐fidelity social learning plays a role in harmonizing and stabilizing the frequency of behaviors within chimpanzee populations, some (if not all) of the forms that chimpanzee behaviors take may develop independently of social learning. If so, they would be latent solutions—behavioral forms that can (re‐)emerge even in the absence of observational opportunities, via individual (re)innovations. Through a combination of individual and low‐fidelity social learning, the population‐wide patterns of behaviors observed in great ape species are then established and stably maintained. This is the Zone of Latent Solutions (ZLS) hypothesis. The current study experimentally tested the ZLS hypothesis for pestle pounding, a wild chimpanzee behavior. We tested the reinnovation of this behavior in semi‐wild chimpanzees at Chimfunshi Wildlife Orphanage in Zambia, Africa, (N = 90, tested in four social groups). Crucially, all subjects were naïve to stick pounding before testing. Three out of the four tested groups reinnovated stick pounding—clearly demonstrating that this behavioral form does not require social learning. These findings provide support for the ZLS hypothesis alongside further evidence for the individual learning abilities of chimpanzees.
HIGHLIGHTS
* Naïve chimpanzees were provided the materials for wild pestle pounding behavior.
* Chimpanzees spontaneously demonstrated the same behavioral form as wild counterparts.
* Individual learning, contra to previous claims, is sufficient to drive this behavioral form in chimpanzees.

Consumers believe similar others would use the same products more often and would find them more useful than they themselves would; this is due to an overestimation of other people’s materialism
Ziano, Ignazio, and Daniel Villanova. 2019. “You’d Use It More Than Me: Overestimating Products’ Usefulness to Others Because of Self-serving Materialism Attributions.” PsyArXiv. May 14. doi:10.31234/osf.io/938m7
Abstract: Six experiments (total n = 3,552, four preregistered, three incentivized) show that consumers believe similar others would use the same products more often and would find them more useful than they themselves would. Overestimation of usefulness of the same product to others is caused by the overestimation of other people’s materialism: we find that this bias reverses when consumers estimate products’ usefulness for someone very low on materialism, and is muted for less materialistic purchases. Overestimation of usefulness is muted for well-known others, as estimation accuracy increases with personal knowledge. Our findings help explain the “X effect,” which is the belief that others are willing to pay more for products (Frederick 2012). These findings connect previously parallel literature streams about self-serving bias in social comparison and biases in self-other monetary evaluations. We discuss theoretical implications for consumers’ above and below average biases, materialism, and the X effect. We discuss practical implications for pricing, negotiation, proxy decision-making, and gift-giving.

Overestimation of usefulness is muted for well-known others, as estimation accuracy increases with personal knowledge. Our findings help explain the “X effect,” which is the belief that others are willing to pay more for products (Frederick 2012). These findings connect previously parallel literature streams about self-serving bias in social comparison and biases in self-other monetary evaluations. We discuss theoretical implications for consumers’ above and below average biases, materialism, and the X effect. We discuss practical implications for pricing, negotiation, proxy decision-making, and gift-giving.
From 2017: The magnitude of pain sensitivity correlated with the extent to which participants experienced unfairness, due to the shared human alarm system of unfairness and pain sensitivity
From 2017: Individual differences in pain sensitivity predict the experience of unfairness. Haixia Wang, Kefeng Li, Xiaofei Xie. Journal of Health Psychology, January 5, 2017. https://doi.org/10.1177/1359105316685902
Abstract: Pain has shaped our evolutionary history, and pain-free experiences are critical for our health. There are, however, enormous individual differences in pain sensitivity, and the psychological consequences of this heterogeneity are only poorly understood. Here, we investigated whether individual differences in pain sensitivity predicted the experience of unfairness. We found that the magnitude of pain sensitivity correlated with the extent to which participants experienced unfairness. This association was due to the shared human alarm system of unfairness and pain sensitivity. This finding may elucidate mechanisms for producing a new and positive cycle of a healthy experience between fairness and feeling pain-free.
Keywords: experience of unfairness, individual differences, pain sensitivity, pain threshold, pain tolerance

Perception of love regulation: Participants thought that they could exaggerate & suppress expressions of infatuation, attachment, & sexual desire, but that they could not start and stop infatuation and attachment, or start sexual desire
Perceived ability to regulate love. Kruti Surti, Sandra J. E. Langeslag. PLOS, May 13, 2019. https://doi.org/10.1371/journal.pone.0216523
Abstract: Research has shown that romantic love can be regulated. We investigated perceptions about love regulation, because these perceptions may impact mental health and influence love regulation application. Two-hundred eighty-six participants completed a series of items online via Qualtrics that assessed perceived ability to up- and down-regulate, exaggerate and suppress the expression of, and start and stop different love types. We also tested individual differences in perceived love regulation ability. Participants thought that they could up- but not down-regulate love in general and that they could up-regulate love in general more than down-regulate it. Participants thought that they could up-regulate infatuation less than attachment and sexual desire. Participants also thought that they could exaggerate and suppress expressions of infatuation, attachment, and sexual desire, but that they could not start and stop infatuation and attachment, or start sexual desire. The more participants habitually used cognitive reappraisal, the more they thought that they could up- and down-regulate infatuation and attachment and up-regulate sexual desire. The more participants were infatuated with their beloved, the more they thought that they could up- but not down-regulate infatuation, attachment, and sexual desire. Finally, participants thought that they could up- and down-regulate happiness more than infatuation These findings are a first step toward the development of psychoeducation techniques to correct inaccurate love regulation perceptions, which may improve mental health and love regulation in daily life.

Impact of public sector salary disclosure laws on university faculty salaries in Canada: The laws reduced salaries on average, although they reduced the gender pay gap between men and women
Pay Transparency and the Gender Gap. Michael Baker, Yosh Halberstam, Kory Kroft, Alexandre Mas, Derek Messacar. NBER Working Paper No. 25834. May 2019. https://www.nber.org/papers/w25834
Abstract: We examine the impact of public sector salary disclosure laws on university faculty salaries in Canada. The laws, which enable public access to the salaries of individual faculty if they exceed specified thresholds, were introduced in different provinces at different points in time. Using detailed administrative data covering the universe of faculty in Canada and an event-study research design, we document three key findings. First, the disclosure laws reduced salaries on average. Second, the laws reduced the gender pay gap between men and women. Third, the closure of the gender gap is primarily in universities where faculty are unionized.

Relationship between paraphilic interests, sex, and sexual and life satisfaction in non-clinical samples: Those with paraphilic interests rarely felt negatively affected
Exploring the relationship between paraphilic interests, sex, and sexual and life satisfaction in non-clinical samples. Crystal L. Mundy, Jan D. Cioe. The Canadian Journal of Human Sexuality, May 13, 2019. https://doi.org/10.3138/cjhs.2018-0041
Abstract: Limited research has indicated that paraphilic interests and behaviours do not necessarily decrease sexual and life satisfaction; some research suggests such interests may actually enhance satisfaction. The present study assessed how paraphilic-associated interests and behaviours were related to sexual and life satisfaction in a sample of 173 men and 356 women. Paraphilic interest rates were similar to existing population-based studies. Men reported significantly higher levels of most paraphilic interests than women, apart from masochism. Those with paraphilic interests rarely felt negatively affected. However, those interested in criminal paraphilic interests or both criminal and legally feasible paraphilic interests had lower levels of sexual satisfaction when they did not engage in paraphilia-associated sexual behaviour. The sexual satisfaction of those interested only in legally feasible paraphilic interests was not impacted whether or not they engaged in paraphilia-associated sexual behaviour. Further analyses indicated that those without a paraphilic interest and those who have a paraphilic interest and have disclosed to their partner have higher levels of sexual satisfaction than those who have not disclosed to their partner or who do not have a stable partner. Additionally, among those who had disclosed to a partner, sexual satisfaction was not affected whether the individual engaged in the paraphilic interest with or without their partner. These results suggest a multifaceted relationship that warrants further consideration and examination.

Rolf Degen summarizing: Changing implicit biases did neither affect explicit biases nor actual behavior (co-authored by Brian A. Nosek, who was significantly involved in developing the IAT)
Forscher, Patrick S., Calvin K. Lai, Jordan Axt, Charles R. Ebersole, Michelle Herman, Patricia G. Devine, and Brian A. Nosek. 2016. “A Meta-analysis of Procedures to Change Implicit Measures.” PsyArXiv. August 15. doi:10.31234/osf.io/dv8tu
Abstract: Using a novel technique known as network meta-analysis, we synthesized evidence from 492 studies (87,418 participants) to investigate the effectiveness of procedures in changing implicit measures, which we define as response biases on implicit tasks. We also evaluated these procedures’ effects on explicit and behavioral measures. We found that implicit measures can be changed, but effects are often relatively weak (|ds| < .30). Most studies focused on producing short-term changes with brief, single-session manipulations. Procedures that associate sets of concepts, invoke goals or motivations, or tax mental resources changed implicit measures the most, whereas procedures that induced threat, affirmation, or specific moods/emotions changed implicit measures the least. Bias tests suggested that implicit effects could be inflated relative to their true population values. Procedures changed explicit measures less consistently and to a smaller degree than implicit measures and generally produced trivial changes in behavior. Finally, changes in implicit measures did not mediate changes in explicit measures or behavior. Our findings suggest that changes in implicit measures are possible, but those changes do not necessarily translate into changes in explicit measures or behavior.

It is reported that identification as a liberal or conservative shapes lifestyle orientations & behaviors; apply caution against wide‐ranging claims
How Much Do Liberal and Conservative Identifiers Differ in the United States? Clem Brooks, Adam Nicholson. Sociological Inquiry, May 12 2019. https://doi.org/10.1111/soin.12286

Abstract: Recent scholarship has reported that identification as a liberal or conservative shapes lifestyle orientations and behaviors. Liberal/conservative differences with respect to such arenas as family and religion go beyond ideological identification research's traditional focus on policy attitudes and political processes. But are differences on non‐political issues as large as those relating to political ones? This question has yet to be addressed, and it is critical to putting in firmer perspective the degree to which liberal and conservative identifiers differ in the United States. We take up investigation through analysis of 106 items from the General Social Survey 2006 panel. We compare ideological identification's influence with respect to political versus non‐political orientations and behaviors. Application of Morgan and Winship's model of causal inference builds from past studies’ cross‐sectional analysis. Results extend ideological identification scholarship, while cautioning against wide‐ranging claims advanced by several public commentators.
The Influence of Ideological Identification
Established Scholarship
Traditionally, the focus of ideological identification scholarship has been on political phenomena, what we will refer to by shorthand as government, law, and politicians. In the United States, there is ample evidence that liberal and conservative identifiers tend to differ across a range of policy attitudes and with respect to their choice of candidate in national elections (e.g., Abramowitz 2013; Abramson et al. 2015; Chapter 6; Erikson and Tedin 2016, Chapter 3). Ideological identification is relevant for political behavior and attitude formation in other nations as well (e.g., Hellwig 2008; Jou and Dalton 2017; Mair 2007), albeit with variation across context.
Identification as a liberal or conservative has traditionally been viewed as a powerful and potentially self‐reinforcing heuristic (Sniderman, Brody, and Tetlock 1991; see also Lau and Sears 1986). When ideological identification is made salient by political cues in the environment, liberal identifiers form positive attitudes toward objects they associate with liberals/liberalism (e.g., government, legal activism) and oppose those associated with conservatives/conservatism (e.g., unregulated markets, traditional social arrangements) (Fuchs and Klingemann 1990; Miller and Shanks 1996). Conservative identifiers follow the reverse expectation. Ideological identification's influence can be self‐reinforcing if identifiers’ choices feed back into their perceptions (Lodge and Taber 2013; see also Granberg and Brent 1980; Merrill, Grofman, and Adams 2001).
Research on polarization among U.S. politicians is relevant to ideological identification scholarship. Poole and Rosenthal's agenda‐setting analysis of roll call voting in Congress (1997; see also McCarty, Poole, and Rosenthal 2006) finds that since the 1960s, Democratic Senators and House Members have moved to the left and their Republican counterparts have moved to the right. For over four decades, American voters have formed policy attitudes and made electoral choices in an environment increasingly defined by cues regarding prototypically liberal versus conservative politicians and policies. This buttresses the established scholarly view of ideological identification as a source of influence as regards voting and policy‐attitude formation.2
