Participants were required to have a Facebook account and to log in to their account to participate in the experiment. The three experimental conditions were real Facebook posts containing a meme about vaccines and a comment thread, where the manipulation occurred. The anti-vaccination condition had mostly anti-vaccination comments (9 of 10); the pro-vaccination condition had mostly pro-vaccination comments (9 of 10); and the mixed condition had an equal number of pro- and anti-vaccination comments (4 pro and 4 anti). Participants could leave a comment on the Facebook post; commenting on the post and intentions to engage with the post were the two dependent variables. Results found no difference in commenting or in intentions among the experimental conditions. Vaccination attitudes did not predict commenting but did predict intentions. There were no interaction effects of condition and attitudes on either commenting or intentions. A total of six comments were made across all conditions. Most of the comments supported vaccines. Results indicate vaccination did not inspire strong enough attitudes to create a spiral of silence effect on Facebook in this experiment.

Social Media and the Spiral of Silence: The Case of Kuwaiti Female Students’ Political Discourse on Twitter By Ali A. Dashti1, Hamed H Al-Abdullah2 and Hasan A Johar3 Abstract The theory of the Spiral of Silence (Noelle-Neumann, 1984), explained why the view of a minority is not presented when the majority view dominates the public sphere. For years the theory of the spiral of silence was used to describe the isolation of minority opinions when seeking help from traditional media, which play a significant role in increasing the isolation.

  • Media Campaigns and Perceptions of Reality
    2820 Media Campaigns and Perceptions of Reality Media Campaigns and Perceptions of Reality Rajiv N. Rimal Johns Hopkins Bloomberg School of Public Health Humans act, at least partly, on the basis of how they think others expect them to act. This means that humans have the capacity to know what others think or expect them to do. Some researchers have argued that understanding what others think is essential to social life and that successful human relationships depend on our ability to read the minds of others (Gavita 2005; → Symbolic Interaction). How good are we, though, at knowing what others think or expect us to do? Data show that there is often a negative correlation between our perceived ability to know what others are thinking and what they are actually thinking (Davis & Kraus 1997). In other words, those who are more confident about their ability to know what others are thinking are, in fact, less accurate, compared to those who are less confident. Accuracy, however, may not be important in this context because what we choose to do usually depends on our perceptions more strongly than on objective reality (→ Media and Perceptions of Reality; Social Perception). Most communication-based campaigns, at their core, have the central mission to change people’s perceptions of reality, whether that reality pertains to something external (such as a political issue, an organization, etc.) or internal (self-concept). For example, political campaigns seek to change people’s perceptions about a particular candidate or issue, commercial campaigns strive to alter people’s attitudes toward a product, and health campaigns seek to alter people’s perceptions about their self-image, ability, or self- worth, just to name a few (→ Advertisement Campaign Management; Election Campaign Communication; Health Campaigns, Communication in).

  • 'Everybody's Doing It': on the Persistence of Bad Social Norms
    Experimental Economics (2020) 23:392–420 https://doi.org/10.1007/s10683-019-09616-z ORIGINAL PAPER ‘Everybody’s doing it’: on the persistence of bad social norms David Smerdon1 · Theo Oferman2 · Uri Gneezy3 Received: 5 July 2017 / Revised: 15 May 2019 / Accepted: 21 May 2019 / Published online: 31 May 2019 © Economic Science Association 2019 Abstract We investigate how information about the preferences of others afects the persis- tence of ‘bad’ social norms. One view is that bad norms thrive even when people are informed of the preferences of others, since the bad norm is an equilibrium of a coordination game. The other view is based on pluralistic ignorance, in which uncer- tainty about others’ preferences is crucial. In an experiment, we fnd clear support for the pluralistic ignorance perspective . In addition, the strength of social interac- tions is important for a bad norm to persist. These fndings help in understanding the causes of such bad norms, and in designing interventions to change them.

  • Propaganda Fitzmaurice
    Propaganda Fitzmaurice Propaganda Katherine Fitzmaurice Brock University Abstract This essay looks at how the definition and use of the word propaganda has evolved throughout history. In particular, it examines how propaganda and education are intrinsically linked, and the implications of such a relationship. Propaganda’s role in education is problematic as on the surface, it appears to serve as a warning against the dangers of propaganda, yet at the same time it disseminates the ideology of a dominant political power through curriculum and practice. Although propaganda can easily permeate our thoughts and actions, critical thinking and awareness can provide the best defense against falling into propaganda’s trap of conformity and ignorance. Keywords: propaganda, education, indoctrination, curriculum, ideology Katherine Fitzmaurice is a Master’s of Education (M.Ed.) student at Brock University. She is currently employed in the private business sector and is a volunteer with several local educational organizations. Her research interests include adult literacy education, issues of access and equity for marginalized adults, and the future and widening of adult education. Email: [email protected] 63 Brock Education Journal, 27(2), 2018 Propaganda Fitzmaurice According to the Oxford English Dictionary (OED, 2011) the word propaganda can be traced back to 1621-23, when it first appeared in “Congregatio de progapanda fide,” meaning “congregation for propagating the faith.” This was a mission, commissioned by Pope Gregory XV, to spread the doctrine of the Catholic Church to non-believers. At the time, propaganda was defined as “an organization, scheme, or movement for the propagation of a particular doctrine, practice, etc.” (OED).

  • Getting Beneath the Surface: Scapegoating and the Systems Approach in a Post-Munro World Introduction the Publication of The
    Getting beneath the surface: Scapegoating and the Systems Approach in a post-Munro world Introduction The publication of the Munro Review of Child Protection: Final Report (2011) was the culmination of an extensive and expansive consultation process into the current state of child protection practice across the UK. The report focused on the recurrence of serious shortcomings in social work practice and proposed an alternative system-wide shift in perspective to address these entrenched difficulties. Inter-woven throughout the report is concern about the adverse consequences of a pervasive culture of individual blame on professional practice. The report concentrates on the need to address this by reconfiguring the organisational responses to professional errors and shortcomings through the adoption of a ‘systems approach’. Despite the pre-occupation with ‘blame’ within the report there is, surprisingly, at no point an explicit reference to the dynamics and practices of ‘scapegoating’ that are so closely associated with organisational blame cultures. Equally notable is the absence of any recognition of the reasons why the dynamics of individual blame and scapegoating are so difficult to overcome or to ‘resist’. Yet this paper argues that the persistence of scapegoating is a significant impediment to the effective implementation of a systems approach as it risks distorting understanding of what has gone wrong and therefore of how to prevent it in the future. It is hard not to agree wholeheartedly with the good intentions of the developments proposed by Munro, but equally it is imperative that a realistic perspective is retained in relation to the challenges that would be faced in rolling out this new organisational agenda.

  • Running Head: Social Media and the Spiral of Silence 1
    Running Head: Social Media and the Spiral of Silence 1 Social Media and the Spiral of Silence Lauren E. Sale Boston University Author Note: This paper was prepared for Introduction to Emerging Media taught by Dr. Shanahan at the College of Communication Running Head: Social Media and the Spiral of Silence 2 Abstract This paper explores Elisabeth Noelle-Neumann's theory of the Spiral of Silence and it's application to social media. Through out the paper, modern day examples of social or civic issues linked to the Spiral of Silence theory. Furthermore, the paper looks at analyses of Noelle-Neumann's theory in an attempt to look at the modern day relevance of the theory. Keywords: Spiral of Silence, Social Media, Ferguson, opinion expression Running Head: Social Media and the Spiral of Silence 3 Most people have seen these scenarios: 1) A friend's Facebook rant about a current news event that gets dozens of likes, comments, or shares. 2) A Twitter discussion with numerous comments bashing the opinion of the original Tweet. 3) Dozens of Facebook friends suddenly sharing the same opinion on some social or political event. What is the explanation behind these occurrences? In today's hyper-connected world, the expression of opinions is at a high. Social media acts as a strong platform for 'voicing' these opinions. However, it is debatable if social media empowers those with unpopular opinions to share them. In fact, some research indicates that only the dominant opinion can thrive on social media. Introduction Elisabeth Noelle-Neumann's iconic book, The Spiral of Silence, analyzes how people and the climate shape opinion formation and sharing (1984).

  • Pluralistic Ignorance Varies with Group Size∗ a Dynamic Model of Impression Management
    Pluralistic Ignorance Varies With Group Size∗ A Dynamic Model of Impression Management Mauricio Fern´andezDuquey December 6, 2018 Abstract I develop a theory of group interaction in which individuals who act sequentially are `impression managers' concerned with signaling what they believe is the majority opin- ion. Equilibrium dynamics may result in most individuals acting according to what they mistakenly believe is the majority opinion, a situation known as `pluralistic ig- norance'. Strong ex ante beliefs over others' views increases pluralistic ignorance in small groups, but decreases it in large groups. Pluralistic ignorance may lead to a perverse failure of collective action, where individuals don't act selfishly because they incorrectly believe they are acting in a way that benefits others, which results in an inefficient drop in social interactions. A policymaker who wants to maximize social welfare will reveal information about the distribution of opinions in large groups, but will manipulate information to make the minority seems larger if the group is small. ∗The latest version of the paper can be found at https://scholar.harvard.edu/duque/research.
