Social media, political polarization, and political disinformation: a review of the scientific literature

The following report is intended to provide an overview of the current state of the literature on the relationship between social media; political polarization; and political “disinformation,” a term used to encompass a wide range of types of information about politics found online, including “fake news,” rumors, deliberately factually incorrect information, inadvertently factually incorrect information, politically slanted information, and “hyperpartisan” news. The review of the literature is provided in six separate sections, each of which can be read individually but that cumulatively are intended to provide an overview of what is known — and unknown — about the relationship between social media, political polarization, and disinformation. The report concludes by identifying key gaps in our understanding of these phenomena and the data that are needed to address them

"She seems more human" : understanding Twitter users' credibility assessments of dementia-related information

The presence of incorrect, medically uncorroborated information on social media may be harmful if people believe it. The purpose of this qualitative study was to identify how Twitter users evaluate the credibility of dementia-related information sources. It used a think-aloud protocol via semi-structured interviews with 13 caregivers. It identified main credibility dimensions, including 13 factors. Participants deployed a combination of heuristics to assess information sources, and engaged in intensive systematic content review based on prior knowledge and relevance. The findings con-tribute to a nuanced understanding of how users evaluate Twitter sources in the health domain. Some of these are discussed in light of the MAIN Model, and prove significant in how practitioners and developers can better under-stand and help users evaluate information

Exploring Twitter as a game platform; strategies and opportunities for microblogging-based games

Recent years have seen the massive daily engagement of players with games that are integrated with online social networking sites, such as Facebook. However, few games have successfully created engaging experiences through integration with microblogging websites. In this paper, we explore the opportunities and challenges in using Twitter as a platform for playing games, through the case study of the game Hashtag Dungeon, a dungeon-crawling game that uses Twitter for collaborative creation of game content. Two studies were carried out. A quantitative user study with 32 participants demonstrated that players found the game engaging and rewarding. A follow-up qualitative study with 8 participants suggests that Twitter integration in this game is meaningful, but that there are concerns over the impact of the game on players’ Twitter profiles. Based on findings from both studies, we propose strategies for the design of Microblogging-based games, and discuss wider implications of social media integration in games

WORD BOMBS: THE USE OF STRATEGIC COMMUNICATIONS TO COUNTER DOMESTIC VIOLENT EXTREMISM

This thesis investigates how implementing strategic communications can counter domestic violent extremist (DVE) behavior in the United States. Strategic communications use counter-messaging based on research and intelligence of the group’s behaviors and perceptions. To develop strategic communications to counter violence, this thesis explores narratives, how they work, their persuasiveness, and how emotions play a role in influencing others. Extremists use social media to propagate images depicting violence and language promoting physical violence. This thesis explores inoculation strategies, nudge theory, psychological and social approaches, and counternarratives to counter DVEs. Reasoned action theory is used as a template for determining how background information, beliefs, and intentions form extremists’ behavior and action. Four case studies are presented using DVE group examples from anarchists, Proud Boys, Boogaloo Boys, and Atomwaffen. Each case study looks at the group’s ideology, violence, social media, demographics, and narratives to better understand the group’s themes. Next, using the reasoned action theory model as well as knowledge of the group and messaging theme, the thesis provides an example of how to craft a counternarrative. This thesis recommends that government and law enforcement invest in inoculation and nudge strategies as well as artificial intelligence, and create special strategic communication teams or units.Civilian, Washington County Sheriff's OfficeApproved for public release.
