Lay Theories of Manipulation: Do Consumers Believe They are Susceptible to Marketers’ Trickery?
No full textMarketers know that persuasion is very hard. So, why are consumers determined that marketers can manipulate them? Across five studies, we show that the beliefs about marketing manipulation have deep psychological roots: Consumers higher in motivations to make sense of their environments tend to not only detect persuasion where it exists, but also where there is none. Such beliefs can be weakened when consumers think of themselves (vs. other consumers) in persuasion situations (study 3) and read concrete (vs. abstract) descriptions of these situations (study 4), but only in consumers with low sense-making drives. Whereas higher sense-making motives manifest in greater false-positive manipulation detection, corresponding abilities negatively affect false-positives and result in more accurate persuasion detection (study 5). The studies also revealed how manipulation beliefs are related to conspiracy ideation, personality traits, beliefs about free will, gender, and age. Implications for marketing segmentation and strategies for attenuating false-positive manipulation detection are discussed
Homophily in Collaborations among US House Representatives, 1981 -- 2018
No full textEffective lawmaking requires collaboration among legislators, who form coalitions to advance their legislative agendas. In the US House of Representatives, these collaborations develop in a context of shifting political party control. In this paper we explore how legislators' party and gender identities simultaneously influence whom they choose as collaborators by examining differential party and gender homophily during a period of shifting party control and increasing representation of women. We introduce new methods for inferring legislative collaboration networks from bill co-sponsorship data, then estimate cross-sectional logistic regression models on these networks from 1981 -- 2015. We find evidence of differential homophily by both party and gender: Republicans and women tend to prefer same-party and same-gender political collaborators more than Democrats and men. However, party homophily (i.e. partisanship) is stronger than gender homophily, suggesting that party is a more salient identity for legislators than gender
The Oldest Manuscript Tradition of the Etymologiae (eighty years after A. E. Anspach)
No full textThe Etymologiae of Isidore of Seville was one of the most widely read works of the early Middle Ages, as is evidenced by the number of surviving manuscripts. August Eduard Anspach’s handlist from the 1940s puts their number at almost 1,200, of which approximately 300 were estimated to have been copied before the year 1000. This article, based on a new manuscript survey of the early medieval manuscripts transmitting the Etymologiae, brings the number of known surviving pre-1000 manuscripts transmitting the Etymologiae to almost 450. Of these, 84 well-preserved codices and 24 fragments contain the canonical Etymologiae, i.e., they reflect the integral transmission of Isidore’s work as an encyclopedia, while 300 well-preserved codices and 21 fragments reflect the selective or non-canonical transmission of the Etymologiae, principally not as an encyclopedia. Due to the uneven survival rates of manuscripts of canonical and non-canonical Etymologiae, it seems likely that the latter accounted for perhaps as much as 80-90% of manuscripts transmitting Isidore’s work before the year 1000. Four non-canonical formats emerge as having been particularly influential in the early Middle Ages: the separate transmission of the first book of the Etymologiae as an ars grammatica; the compilation of various catechetical collections, sometimes in question-and-answer form, from books VI, VII, and VIII of the Etymologiae; the incorporation of material from books V and IX into law collections; and the incorporation of segments from books III, V, VI, and XIII into computistic manuals. The surviving manuscripts suggest that the latter format emerged in the insular world, while the others are more distinctly Carolingian. Northern France and northern Italy emerge as the two most important regional hubs of the copying of the Etymologiae in the ninth and tenth centuries. While in the former region, non-canonical formats seem to have been the most important vehicle of the transmission of material from Isidore’s work, in the latter, the canonical format may have been more influential, indicating that there existed regional differences in the reception of the Etymologiae
Efficient Conservation of the Brazilian Amazon: Estimates from a Dynamic Model
No full textThis paper estimates the Brazilian Amazon’s carbon-efficient forest cover -- i.e. when farmers internalize the social cost of carbon. We propose a dynamic discrete choice land-use model and estimate it using a panel of land use and carbon stock of 5.7 billion pixels between 2008 and 2017. The business-as-usual scenario implies an inefficient release of 42 billion tons of CO2 in the long run resulting from the deforestation of an area twice the size of France. A carbon tax that makes farmers internalize the social cost of carbon would implement the efficient allocation and generate welfare gains exceeding 1.6 trillion dollars. Responses from a carbon tax are highly convex: a carbon tax of only $10/ton would preserve 95% of the efficient carbon stock. An excise tax on cattle ranching, a second-best policy, achieves at most 87% of the first-best welfare gains
Working toward a purpose: Examining the cross-sectional and longitudinal effects of work characteristics on sense of purpose
No full textObjective: Employment appears to influence employees’ sense of purpose, insofar as work roles can provide life direction and allow individuals to fulfill meaningful aims or have regular goal-related activity engagement. However, research is needed on which specific characteristics of the work predict employees’ sense of purpose. The current study sought to quantify the degree to which specific work characteristics, including skill variety, autonomy, coworker support, and supervisor support, were associated with initial levels and changes in purpose. Additionally, we examine positive and negative work-home spillover as moderators of these relationships. Methods: We examined hypothesized relationships in a subsample (N = 4,963) of a nationally representative panel study which included between two and three assessments of work characteristics, spillover, and sense of purpose, each roughly 10 years apart. Results: Using multilevel models to assess within-person associations and lagged effects, we found that greater skill variety and coworker support but not autonomy or supervisor support, were associated with higher levels of purpose. Moreover, increases in purpose were associated with higher initial levels of skill variety. These relationships were not moderated by spillover. Conclusion: Individuals with skill variety and coworker support at work appear to experience the strongest levels of sense of purpose
The Network Structure of Schema Modes
No full textA fundamental question in psychotherapy is whether interventions should target client problems (i.e., problem-focused approaches) or client strengths (i.e., strength-focused approaches). In this study, we first propose to address this question from a network perspective on schema modes (i.e., healthy or dysfunctional patterns of co-occurring emotions, cognitions, and behaviors). From this perspective, schema modes mutually influence each other (e.g., healthy modes reduce dysfunctional modes). Recent evidence suggests that changes in modes that are strongly associated to other modes (i.e., central modes) could be associated with greater treatment effects. Therefore, we suggest that research should investigate the relative centrality of healthy and dysfunctional modes. To make an exploratory start, we investigated the cross-sectional network structure of schema modes in a clinical (comprising individuals diagnosed with paranoid, narcissistic, histrionic, and Cluster C personality disorders) and non-clinical sample. Results showed that, in both samples, the Healthy Adult was significantly less central than several dysfunctional modes (e.g., Undisciplined Child and Abandoned and Abused Child). Although our study cannot draw causal conclusions, this finding could suggest that weakening dysfunctional modes (compared to strengthening the Healthy Adult) might be more effective in decreasing other dysfunctional modes. Our study further indicates that several schema modes are negatively associated, which could suggest that decreasing one might increase another. Finally, the Healthy Adult was among the modes that most strongly discriminated between clinical and non-clinical individuals. Longitudinal and experimental research into the network structure of schema modes is required to further clarify the relative influence of schema modes
Understanding the aging lexicon by linking individuals' experience, semantic networks, and cognitive performance
No full textPeople undergo many idiosyncratic experiences throughout their lives that may contribute to individual differences in the size and structure of their knowledge representations. Ultimately, these can have important implications for individuals' cognitive performance. We review evidence that suggests a relationship between individual experiences, the size and structure of semantic representations, as well as individual and age differences in cognitive performance. We conclude that the extent to which experience-dependent changes in semantic representations contribute to individual differences in cognitive aging remains unclear. To help fill this gap, we outline an empirical agenda involving the concurrent assessment of large-scale semantic networks and cognitive performance in younger and older adults, and present preliminary data to establish the feasibility and limitations of such empirical approaches
Adjusting for Publication Bias in JASP & R - Selection Models, PET-PEESE, and Robust Bayesian Meta-Analysis
No full textMeta-analyses are essential for cumulative science, but their validity can be compromised by publication bias. In order to mitigate the impact of publication bias, one may apply publication bias adjustment techniques such as PET-PEESE and selection models. Implemented in JASP & R, these methods allow researchers without programming experience to conduct state-of-the-art publication bias adjusted meta-analysis. In this tutorial, we demonstrate how to conduct a publication bias adjusted meta-analysis in JASP & R and interpret the results. First, we explain two frequentist bias correction methods: PET-PEESE and selection models. Second, we introduce robust Bayesian meta-analysis (RoBMA), a Bayesian approach that simultaneously considers both PET-PEESE and selection models. We illustrate the methodology on an example data set, provide instructional video (https://bit.ly/pubbias), R-markdown script (https://osf.io/uhaew/), and discuss the interpretation of the results. Finally, we include concrete guidance on reporting the meta-analytic results in an academic article
A Peace Baby Boom? Evidence from Colombia's Peace Agreement
No full textViolence affects households’ preferences, perceptions, and constraints regarding fertility choices. What happens when violence ends? Using administrative data from Colombia, we find that the end of a long internal conflict differentially increased fertility by 3.2 percent in areas exposed to violence. The effect is present across all reproductive ages and larger in municipalities with higher levels of violence exposure at baseline. This differential fertility increase is not driven by health supply indicators, by the mortality of newborns and infants, or by differential migration. We provide evidence consistent with an increased perception of security, higher returns for childbearing, and more parental investment
Erroneous beliefs and emotional involvement as predictors of athletes´ sports betting behavior and problems
No full textThe sports betting market has been growing rapidly over the last years, as have reports of problematic gambling behavior associated with sports. Due to high prevalence rates and well documented struggles of international stars, athletes have been highlighted as a group at-risk. However, there currently remains a lack of research on specific risk-factors or mechanisms. To examine the influence of two potential risk-factors (erroneous beliefs and emotional involvement) on sports betting behaviour and problems, 201 athletes with different levels of expertise completed an online questionnaire. Using principal components as well as regression analyses, we find that emotional involvement strongly predicts betting problems whereas erroneous beliefs do not. However, distorted cognitions / beliefs were associated with higher volumes and more frequent betting activities. This might contribute to betting problems in the long run. These results highlight athletes´ emotional involvement and erroneous beliefs as potential targets for future intervention and prevention efforts
