Argument Strength is in the Eye of the Beholder: Audience Effects in Persuasion

Americans spend about a third of their time online, with many participating in online conversations on social and political issues. We hypothesize that social media arguments on such issues may be more engaging and persuasive than traditional media summaries, and that particular types of people may be more or less convinced by particular styles of argument, e.g. emotional arguments may resonate with some personalities while factual arguments resonate with others. We report a set of experiments testing at large scale how audience variables interact with argument style to affect the persuasiveness of an argument, an under-researched topic within natural language processing. We show that belief change is affected by personality factors, with conscientious, open and agreeable people being more convinced by emotional arguments.Comment: European Chapter of the Association for Computational Linguistics (EACL 2017

Values for gender roles and relations among high school and non-high school adolescents in a Maya community in Chiapas, Mexico.

In the current study, I describe values for gender roles and cross-sex relations among adolescents growing up in a southern Mexican Maya community in which high school was introduced in 1999. A total of 80 adolescent girls and boys, half of whom were attending the new high school, provided their opinions on two ethnographically derived vignettes that depicted changes in gender roles and relations occurring in their community. Systematic coding revealed that adolescents not enrolled in high school tended to prioritise ascribed and complementary gender roles and emphasise the importance of family mediation in cross-sex relations. Adolescents who were enrolled in high school tended to prioritise equivalent and chosen gender roles, and emphasised personal responsibility and personal fulfillment in cross-sex relations. Perceptions of risks and opportunities differed by gender: girls favourably evaluated the expansion of adult female role options, but saw risks in personal negotiations of cross-sex relations; boys emphasised the loss of the female homemaker role, but favourably evaluated new opportunities for intimacy in cross-sex relations

The ‘anti-social’ nature of prosocial research; a psychosocial critique

This article provides a critical review of recent psychological articles on prosocial behaviour. Even though it focuses on a specific section of this literature – giving to charities and prosocial responses to humanitarian disasters – the paper aims to offer a wider critique as it interrogates the epistemological and methodological underpinnings of the prosocial literature as a whole. It aims to illustrate how the problematic aspects of traditional quantitative, deductive, experimental research in prosocial behaviour in general, when applied to giving to charities, preclude a deeper and more complex understanding of a phenomenon quintessentially social and altruistic. I identify three specific issues that make mainstream approaches to prosocial behaviour problematic and limited in scope. The first relates to the insularity of mainstream psychology and the lack of contextualisation of its findings, in particular the problematic neglect of ideological and socio-historical factors in prosocial behaviour. The second relates to mainstream psychology's disregard for the role played by conflict, contradiction and ambivalence, in attitudes and decision making as well as in the emotional aspects of prosocial behaviour. The third looks at the constraints imposed by scientifically inspired methods, how they predetermine the range of participants' responses and make it hard to apply the findings to real life situations. I claim that these epistemological and methodological constraints severely limit the applicability and comprehensiveness of current research. The discussion of these issues is woven through the review and uses some specific studies to illustrate the limitations imposed by these constraints. Throughout the paper I also argue for the need to incorporate a psychosocial approach to research into prosocial behaviour

The Ethics of Lobbying: Testing an Ethical Framework for Advocacy in Public Relations

This study evaluates the ethical criteria lobbyists consider in their professional activities using Ruth Edgett’s model for ethically-desirable public relations advocacy. Data were collected from self-administered surveys of 222 registered lobbyists in Oregon. A factor analysis reduced 18 ethical criteria to seven underlying factors describing lobbyists’ ethical approaches to their work. Results indicate that lobbyists consider the following factors in their day-to-day professional activities: situation, strategy, argument, procedure, nature of lobbying, priority, and accuracy. This framework, derived from Edgett’s 10 criteria, illustrates the importance of context while incorporating ideas from recognized ethical theories

Quantifying the Effect of Sentiment on Information Diffusion in Social Media

Social media have become the main vehicle of information production and consumption online. Millions of users every day log on their Facebook or Twitter accounts to get updates and news, read about their topics of interest, and become exposed to new opportunities and interactions. Although recent studies suggest that the contents users produce will affect the emotions of their readers, we still lack a rigorous understanding of the role and effects of contents sentiment on the dynamics of information diffusion. This work aims at quantifying the effect of sentiment on information diffusion, to understand: (i) whether positive conversations spread faster and/or broader than negative ones (or vice-versa); (ii) what kind of emotions are more typical of popular conversations on social media; and, (iii) what type of sentiment is expressed in conversations characterized by different temporal dynamics. Our findings show that, at the level of contents, negative messages spread faster than positive ones, but positive ones reach larger audiences, suggesting that people are more inclined to share and favorite positive contents, the so-called positive bias. As for the entire conversations, we highlight how different temporal dynamics exhibit different sentiment patterns: for example, positive sentiment builds up for highly-anticipated events, while unexpected events are mainly characterized by negative sentiment. Our contribution is a milestone to understand how the emotions expressed in short texts affect their spreading in online social ecosystems, and may help to craft effective policies and strategies for content generation and diffusion.Comment: 10 pages, 5 figure

The Limits of Appealing to Disgust

The rhetoric of disgust is common in moral discourse and political propaganda. Some believe it's pernicious, for it convinces without evidence. But scientific research now suggests that disgust is typically an effect, not a cause, of moral judgment. At best the emotion on its own only sometimes slightly amplifies a moral belief one already has. Appeals to disgust are thus dialectically unhelpful in discourse that seeks to convince. When opponents of abortion use repulsive images to make their case, they convince few, even if they rally their base. When champions of animal rights show graphic depictions of the torturous conditions of animals in factory farms, they convince only those previously ignorant of the severity of such conditions. Ultimately, disgust may be less pernicious than it is useless

Attainable and Relevant Moral Exemplars Are More Effective than Extraordinary Exemplars in Promoting Voluntary Service Engagement

The present study aimed to develop effective moral educational interventions based on social psychology by using stories of moral exemplars. We tested whether motivation to engage in voluntary service as a form of moral behavior was better promoted by attainable and relevant exemplars or by unattainable and irrelevant exemplars. First, experiment 1, conducted in a lab, showed that stories of attainable exemplars more effectively promoted voluntary service activity engagement among undergraduate students compared with stories of unattainable exemplars and non-moral stories. Second, experiment 2, a middle school classroom-level experiment with a quasi-experimental design, demonstrated that peer exemplars, who are perceived to be attainable and relevant to students, better promoted service engagement compared with historic figures in moral education classes
