Social Norm Perception in Groups With Outliers

Social Norm Perception in Groups With Outliers. Jennifer Dannals and Dale Miller. Journal of Experimental Psychology: General, https://www.ncbi.nlm.nih.gov/pubmed/28682092

Abstract: Social outliers draw a lot of attention from those inside and outside their group and yet little is known about their impact on perceptions of their group as a whole. The present studies examine how outliers influence observers' summary perceptions of a group's behavior and inferences about the group's descriptive and prescriptive norms. Across 4 studies (N = 1,718) we examine how observers perceive descriptive and prescriptive social norms in groups containing outliers of varying degrees. We find consistent evidence that observers overweight outlying behavior when judging the descriptive and prescriptive norms, but overweight outliers less as they become more extreme, especially in perceptions of the prescriptive norm. We find this pattern across norms pertaining to punctuality (Studies 1-2 and 4) and clothing formality (Study 3) and for outliers who are both prescriptively and descriptively deviant (e.g., late arrivers), as well as for outliers who are only descriptive deviants (e.g., early arrivers). We further demonstrate that observers' perceptions of the group shift in the direction of moderate outliers. This occurs because observers anchor on the outlier's behavior and adjust their recollections of nonoutlying individuals, making their inferences about the group's average behavior more extreme.

Comparison Neglect in Upgrade Decisions

Comparison Neglect in Upgrade Decisions. Aner Sela and Robyn LeBoeuf. Journal of Marketing Research, https://doi.org/10.1509/jmr.14.0394

Abstract: To properly evaluate a potential product upgrade, consumers should compare the upgraded option with the product they already own to assess the upgrade's added utility. However, although consumers explicitly and spontaneously acknowledge the importance of comparing the upgrade with the status quo, the authors find that they often fail to do so. Consequently, consumers frequently buy product upgrades that they would not have bought had they followed their own advice. Five experiments, involving both real and hypothetical upgrade decisions, show that even when the status quo option is represented in the decision context, if consumers are not explicitly prompted to reflect on it or compare it with the upgraded option, they often do not compare it with the upgrade and thus show an elevated likelihood of upgrading. The experiments suggest that this "comparison neglect" increases upgrade likelihood by making people overlook the similarities between the upgraded and status quo options and that it persists even when deliberation effort is high. The findings have important implications for theory, marketing practice, and consumer welfare.

When outgroup negativity trumps ingroup positivity: Fans of the Boston Red Sox and New York Yankees place greater value on rival losses than own-team gains

When outgroup negativity trumps ingroup positivity: Fans of the Boston Red Sox and New York Yankees place greater value on rival losses than own-team gains. Steven Lehr, Meghan Ferreira & Mahzarin Banaji. Group Processes & Intergroup Relations, http://journals.sagepub.com/doi/abs/10.1177/1368430217712834

Abstract: Much research suggests that ingroup positivity is more central than outgroup negativity. We argue that this conclusion is incomplete as a description of the totality of intergroup emotions. In 4 studies, we use a novel measure of willingness to pay for intergroup gains and losses to examine the intergroup emotions of fans of the Boston Red Sox and New York Yankees. Results indicate that pleasure from a powerful rival's losses can outstrip that from gains of one's own group (Studies 1-2), and these patterns extend into domains not immediately relevant to the competition (Studies 3-4). A reversal in the competitive position of the two teams in the 2012-2013 season allowed us to examine whether fluctuations in competitive status moderated this pattern (Studies 3-4). Indeed, fans of the rival teams frequently valued outgroup losses more than ingroup gains, and this effect was particularly strong when one's own team was behind in the rivalry.

Political Conformity: Event-Study Evidence from the United States

Political Conformity: Event-Study Evidence from the United States. Ricardo Perez-Truglia. Review of Economics and Statistics, http://dx.doi.org/10.2139/ssrn.2427146

Abstract: We propose that individuals are more politically active in more like-minded social environments. To test this hypothesis, we combine administrative data from the Federal Election Commission and the United States Postal Service. We identify 45,000 individuals who contributed to Barack Obama’s 2008 presidential campaign and who changed residences either before or after the 2012 election cycle. We examine whether living in an area with a higher share of Democrats causes higher contributions to Obama. We disentangle the direction of causality by exploiting the timing of residential mobility with an event-study analysis. We find that conformity effects are economically significant: increasing the share of Democrats by 1% increases the contribution to Obama by 0.11% (p-value<0 .01="" 27="" a="" analysis.="" attributed="" be="" br="" can="" conformity="" contributions="" counterfactual="" degree="" effects.="" estimates="" find="" for="" geographic="" in="" last="" model="" of="" polarization="" provide="" reduced-form="" that="" the="" to="" uses="" we="">

Limited individual attention and online virality of low-quality information

Limited individual attention and online virality of low-quality information. Xiaoyan Qiu et al. Nature Human Behaviour, June 2017, https://www.nature.com/articles/s41562-017-0132

Abstract: Social media are massive marketplaces where ideas and news compete for our attention. Previous studies have shown that quality is not a necessary condition for online virality and that knowledge about peer choices can distort the relationship between quality and popularity. However, these results do not explain the viral spread of low-quality information, such as the digital misinformation that threatens our democracy. We investigate quality discrimination in a stylized model of an online social network, where individual agents prefer quality information, but have behavioural limitations in managing a heavy flow of information. We measure the relationship between the quality of an idea and its likelihood of becoming prevalent at the system level. We find that both information overload and limited attention contribute to a degradation of the market's discriminative power. A good tradeoff between discriminative power and diversity of information is possible according to the model. However, calibration with empirical data characterizing information load and finite attention in real social media reveals a weak correlation between quality and popularity of information. In these realistic conditions, the model predicts that low-quality information is just as likely to go viral, providing an interpretation for the high volume of misinformation we observe online.

Fact-Checking Effectiveness as a Function of Format and Tone: Evaluating FactCheck.org and FlackCheck.org

Fact-Checking Effectiveness as a Function of Format and Tone: Evaluating FactCheck.org and FlackCheck.org. Dannagal Young et al. Journalism & Mass Communication Quarterly, http://journals.sagepub.com/doi/abs/10.1177/1077699017710453

Abstract: This experiment explores the role of information format (print vs. video) and tone (humorous-nonhumorous) in shaping message interest and belief correction in the context of political fact-checking (N = 525). To understand the mechanisms by which audience misperceptions may be reduced, this experiment tests the belief-correcting effectiveness of a humorous fact-checking video produced by Flackcheck.org, a long-form FactCheck.org print article on the same topic, a nonhumorous video debunking the same set of claims, an unrelated humorous video, and a non-stimulus control group. Mediating psychological mechanisms (message interest, counterargumentation, message discounting) and message perceptions (message confusion) are explored. Results suggest video (humorous or nonhumorous) is an effective way to reduce audience misperceptions by increasing message attention and reducing confusion.

Enhancement of multitasking performance and neural oscillations by transcranial alternating current stimulation

Enhancement of multitasking performance and neural oscillations by transcranial alternating current stimulation. Wan-Yu Hsu et al. PLoS One, May 2017, https://doi.org/10.1371/journal.pone.0178579

Abstract: Multitasking is associated with the generation of stimulus-locked theta (4-7 Hz) oscillations arising from prefrontal cortex (PFC). Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique that influences endogenous brain oscillations. Here, we investigate whether applying alternating current stimulation within the theta frequency band would affect multitasking performance, and explore tACS effects on neurophysiological measures. Brief runs of bilateral PFC theta-tACS were applied while participants were engaged in a multitasking paradigm accompanied by electroencephalography (EEG) data collection. Unlike an active control group, a tACS stimulation group showed enhancement of multitasking performance after a 90-minute session (F1,35 = 6.63, p = 0.01, ηp2 = 0.16; effect size = 0.96), coupled with significant modulation of posterior beta (13-30 Hz) activities (F1,32 = 7.66, p = 0.009, ηp2 = 0.19; effect size = 0.96). Across participant regression analyses indicated that those participants with greater increases in frontal theta, alpha and beta oscillations exhibited greater multitasking performance improvements. These results indicate frontal theta-tACS generates benefits on multitasking performance accompanied by widespread neuronal oscillatory changes, and suggests that future tACS studies with extended treatments are worth exploring as promising tools for cognitive enhancement.

National Trauma and the Fear of Foreigners: How Past Geopolitical Threat Heightens Anti-Immigration Sentiment Today

National Trauma and the Fear of Foreigners: How Past Geopolitical Threat Heightens Anti-Immigration Sentiment Today. Wesley Hiers, Thomas Soehl & Andreas Wimmer. Social Forces,  https://doi.org/10.1093/sf/sox045

Abstract: This paper introduces a historical, macro-political argument into the literature on anti-immigration sentiment, which has mainly considered individual-level predictors such as education or social capital as well as country-level factors such as fluctuations in labor market conditions, changing composition of immigration streams, or the rise of populist parties. We argue that past geopolitical competition and war have shaped how national identities formed and thus also contemporary attitudes toward newcomers: countries that have experienced more violent conflict or lost territory and sovereignty developed ethnic (rather than civic) forms of nationalism and thus show higher levels of anti-immigration sentiment today. We introduce a geopolitical threat scale and score 33 European countries based on their historical experiences. Two anti-immigration measures come from the European Social Survey. Mixed-effects, ordinal logistic regression models reveal strong statistical and substantive significance for the geopolitical threat scale. Furthermore, ethnic forms of national identification do seem to mediate this relationship between geopolitical threat and restrictionist attitudes. The main analysis is robust to a wide variety of model specifications, to the inclusion of all control variables known to affect anti-immigration attitudes, and to a series of alternative codings of the geopolitical threat scale.

How Self-Control Shapes the Meaning of Choice

How Self-Control Shapes the Meaning of Choice. Aner Sela, Jonah Berger and Joshua Kim
Journal of Consumer Research, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2962435

Abstract: Self-control is an important driver of choice, but might it also change choice's meaning, making it seem less indicative of preference? Decades of research suggest that preference and choice are often intertwined. Choice often originates from one's preferences. As a result, choice is often seen as a reflection of preference, leading people to infer their preferences by observing their own choices. We suggest that self-control attenuates this process. Because self-control often overrides personal desires in favor of external constraints, norms, and long-term considerations, we propose that self-control is associated with a sense of attenuated correspondence between choice and individual preference. Five experiments suggest that when the notion of self-control is salient, people are less likely to see their choices as reflecting their preferences or to infer preference from previous choices. As a result, evoking the notion of self-control attenuates the tendency to view choice as indicative of preference, even in contexts unrelated to where self-control was originally evoked. Thus, self-control shapes not only choice itself, but also the perceived meaning of choice.

Changes in cognitive flexibility and hypothesis search across human life history from childhood to adolescence to adulthood

Changes in cognitive flexibility and hypothesis search across human life history from childhood to adolescence to adulthood. Alison Gopnik et al. Proceedings of the National Academy of Sciences, Jul 25 2017, Pages 7892-7899, www.pnas.org/content/114/30/7892.short

Abstract: How was the evolution of our unique biological life history related to distinctive human developments in cognition and culture? We suggest that the extended human childhood and adolescence allows a balance between exploration and exploitation, between wider and narrower hypothesis search, and between innovation and imitation in cultural learning. In particular, different developmental periods may be associated with different learning strategies. This relation between biology and culture was probably coevolutionary and bidirectional: life-history changes allowed changes in learning, which in turn both allowed and rewarded extended life histories. In two studies, we test how easily people learn an unusual physical or social causal relation from a pattern of evidence. We track the development of this ability from early childhood through adolescence and adulthood. In the physical domain, preschoolers, counterintuitively, perform better than school-aged children, who in turn perform better than adolescents and adults. As they grow older learners are less flexible: they are less likely to adopt an initially unfamiliar hypothesis that is consistent with new evidence. Instead, learners prefer a familiar hypothesis that is less consistent with the evidence. In the social domain, both preschoolers and adolescents are actually the most flexible learners, adopting an unusual hypothesis more easily than either 6-y-olds or adults. There may be important developmental transitions in flexibility at the entry into middle childhood and in adolescence, which differ across domains.

A Birther and a Truther: The Influence of the Authoritarian Personality on Conspiracy Beliefs

A Birther and a Truther: The Influence of the Authoritarian Personality on Conspiracy Beliefs. Sean Richey. Politics & Policy, June 2017, Pages 465-485, http://onlinelibrary.wiley.com/doi/10.1111/polp.12206/full

Abstract: I find that 10 percent of Americans believe in both "trutherism" and "birtherism." Even among citizens who say they like Bush or Obama, or are from the same party, many still believe in conspiracies implicating the presidents. It is crucial to understand why so many Americans believe obviously erroneous conspiracies that denigrate a president who otherwise has their support. I predict that the authoritarian personality creates a predisposition to believe in conspiracies based on the tendency of those high in this trait to have greater anxiety and cognitive difficulties with higher order thinking. Using 2012 American National Election Study data, I find a clear and robust relationship between the authoritarian personality and conspiratorial beliefs. In all models, authoritarianism is a chief predictor for a predisposition toward both conspiratorial beliefs. This suggests that psychological propensities are an important explanation of why so many citizens believe in conspiracy theories.

Brain Drain: The Mere Presence of One's Own Smartphone Reduces Available Cognitive Capacity

Brain Drain: The Mere Presence of One's Own Smartphone Reduces Available Cognitive Capacity. Adrian Ward et al. Journal of the Association for Consumer Research, April 2017, Pages 140-154, http://www.journals.uchicago.edu/doi/abs/10.1086/691462

Abstract: Our smartphones enable - and encourage - constant connection to information, entertainment, and each other. They put the world at our fingertips, and rarely leave our sides. Although these devices have immense potential to improve welfare, their persistent presence may come at a cognitive cost. In this research, we test the "brain drain" hypothesis that the mere presence of one's own smartphone may occupy limited-capacity cognitive resources, thereby leaving fewer resources available for other tasks and undercutting cognitive performance. Results from two experiments indicate that even when people are successful at maintaining sustained attention - as when avoiding the temptation to check their phones - the mere presence of these devices reduces available cognitive capacity. Moreover, these cognitive costs are highest for those highest in smartphone dependence. We conclude by discussing the practical implications of this smartphone-induced brain drain for consumer decision-making and consumer welfare.

On the inability to ignore useless advice: A case for anchoring in the judge-advisor-system

On the inability to ignore useless advice: A case for anchoring in the judge-advisor-system. Thomas Schultze, Andreas Mojzisch & Stefan Schulz-Hardt. Experimental Psychology, May/June 2017, Pages 170-183, http://econtent.hogrefe.com/doi/abs/10.1027/1618-3169/a000361

Abstract: Research in the judge-advisor-paradigm suggests that advice is generally utilized less than it should be according to its quality. In a series of four experiments, we challenge this widely held assumption. We hypothesize that when advice quality is low, the opposite phenomenon, namely overutilization of advice, occurs. We further assume that this overutilization effect is the result of anchoring: advice serves as an anchor, thus causing an adjustment toward even useless advice. The data of our four experiments support these hypotheses. Judges systematically adjusted their estimates toward advice that we introduced to them as being useless, and this effect was stable after controlling for intentional utilization of this advice. Furthermore, we demonstrate that anchoring-based adjustment toward advice is independent of advice quality. Our findings enhance our understanding of the processes involved in advice taking and identify a potential threat to judgment accuracy arising from an inability to discount useless advice.
