TALK TITLE: Exposure to the Russian Internet Research Agency foreign influence campaign on Twitter in the 2016 US election and its relationship to attitudes and voting behavior
ABSTRACT: There is widespread concern that foreign actors are using social media to interfere in elections worldwide. Yet data have been unavailable to investigate links between exposure to foreign influence campaigns and political behavior. Using longitudinal survey data from US respondents linked to their Twitter feeds, we quantify the relationship between exposure to the Russian foreign influence campaign and attitudes and voting behavior in the 2016 US election. We demonstrate, first, that exposure to Russian disinformation accounts was heavily concentrated: only 1% of users accounted for 70% of exposures. Second, exposure was concentrated among users who strongly identified as Republicans. Third, exposure to the Russian influence campaign was eclipsed by content from domestic news media and politicians. Finally, we find no evidence of a meaningful relationship between exposure to the Russian foreign influence campaign and changes in attitudes, polarization, or voting behavior. The results have implications for understanding the limits of election interference campaigns on social media.

TALK TITLE: Computational Methods to Measure and Mitigate Online Disinformation
ABSTRACT: The Web has allowed disinformation to reach an unprecedented scale, allowing it to become ubiquitous and harm society in multiple ways. To be able to fully understand this phenomenon, we need computational tools able to trace false information, monitoring a plethora of online platforms and analyzing not only textual content but also images and videos. In this talk, I will present my group's efforts in developing tools to automatically monitor and model online disinformation. These tools allow us to recommend social media posts that should receive soft moderation, to identify false and misleading images posted online, and to detect inauthentic social network accounts that are likely involved in state-sponsored influence campaigns. I will then discuss our research on understanding the potentially unwanted consequences of suspending misbehaving users on social media.

TALK TITLE: AI-Driven Approaches for Countering Influence Campaigns in Socio-Technical Systems
ABSTRACT: The proliferation of online platforms and social media has sparked a surge in information operations designed to manipulate public opinion on a massive scale, posing significant harm at both the individual and societal levels. In this talk, I will outline a research agenda focused on identifying, investigating, and mitigating orchestrated influence campaigns and deceptive activities within socio-technical systems. I will start by detailing my research efforts in designing AI-based approaches for detecting state-backed troll accounts on social media. Modeling human decision-making as a Markov Decision Process and using an Inverse Reinforcement Learning framework, I will illustrate how we can extract the incentives that social media users respond to and differentiate genuine users from state-sponsored operators. Next, I will delve into a set of innovative approaches I developed to uncover signals of inauthentic, coordinated behaviors. By combining embedding techniques to unveil unexpected similarities in the activity patterns of social media users, along with graph decomposition methods, I will show how we can reveal network structures that pinpoint coordinated groups orchestrating information operations. Through these approaches, I will provide actionable insights to inform regulators in shaping strategies to tame harm, discussing challenges and opportunities to improve the resilience of the information ecosystem, including the potential for interdisciplinary collaborations to address these complex issues.
This is a hybrid event, co-hosted by the Center for Complex Networks and Systems Research. The talk will be held in room 2005 of the Luddy AI building. Please indicate if you will be attending in-person as food will be provided.

TALK TITLE: Supporting Effective Peer Response to Misinformation on Social Media
ABSTRACT: Online information is difficult to navigate. While large organizations and social media platforms have taken steps to amplify accurate information and combat rumors and misinformation online, much work to offer correct information and quality resources happens at a more local scale, with individuals and community moderators engaging with (mis)information posted by their peers. In this talk, I will discuss the role of peer-based misinformation response, drawing on results from qualitative and quantitative studies of people’s engagement with potential misinformation online, and sharing our vision and preliminary learnings developing a software tool (the “ARTT Guide”) that supports constructive online conversations and peer-based misinformation response.

TALK TITLE: Subscriptions and external links help drive resentful users to alternative and extremist YouTube videos
ABSTRACT: Do online platforms facilitate the consumption of potentially harmful content? Using paired behavioral and survey data provided by participants recruited from a representative sample in 2020 (n=1,181), we show that exposure to alternative and extremist channel videos on YouTube is heavily concentrated among a small group of people with high prior levels of gender and racial resentment. These viewers often subscribe to these channels (prompting recommendations to their videos) and follow external links to them. In contrast, non-subscribers rarely see or follow recommendations to videos from these channels. Our findings suggest YouTube's algorithms were not sending people down "rabbit holes" during our observation window in 2020, possibly due to changes that the company made to its recommender system in 2019. However, the platform continues to play a key role in facilitating exposure to content from alternative and extremist channels among dedicated audiences.
