Do Recommender Systems Mobilize People for Collective Actions? Is it Dependent on Recommenders’ Design or People’s Usage?


Tools and platforms that collective actions such as protests and parades rely on to mobilize, organize, and communicate with people have evolved tremendously due to technological advancement. One important change is the wide application of social media, which heavily incorporates algorithms to rank, filter, and disseminate content. This set of algorithms is called recommender systems (“RS” for short). 

 

Digital activism researchers have noticed the role of RS in influencing collective actions, but most of them concentrate on the perspective of activists. Activists use RS content filtering and aggregation functions to facilitate collective actions on social media while trying to mitigate the constraints placed by algorithms such as information overload and content exclusion (Etter & Albu, 2021). Moreover, they consciously tailor their content strategies to RS on different platforms (Dumitrica & Felt, 2020).


However, it is yet to be known how activists using RS for collective actions might influence other people to act as a group, such as their feelings of connectedness, knowledge about the compaign, interest in the topic, etc.. Better understanding in this regard can help activists make more informed choices of digital tools and develop mobilizing strategies in collective actions.


To this end, my collaborators and I plan to look into the effects of people’s RS usage on factors that might influence people’s engagement in collective actions. We want to explore whether, and if any, how different RS mobilize people for collective actions. Platforms included in our study are mainly social media, such as Facebook, Instagram, X, etc., because RS are heavily incorporated in these platforms’ infrastructures. 


We initially anticipated that the variation of RS effects might arise from differences in RS design across platforms. For example, some RS, such as those on Facebook, prioritize interactions users make with other accounts. It means that these RSFacebook prioritize the uses of likes, comments, sharing etc. for ranking and filtering content. While other RS, such as TikTok, give more weight to users’ own activities like watch history over their networks in creating recommendations (the “for me” page).


What we find tricky but also fascinating when we delve deeper into this idea is that the interaction between users and RS might complicate the categorization we proposed above. While RS on a platform are designed to be equipped with features enabling and encouraging users' connections, people might use this platform in a very solitary way, for example, never following anyone on Instagram. Put it another way, RS effects on mobilizing people might not only depend on their design but also potentially on how people use them.


How to take this interaction between users and RS into account when differentiating recommenders? Which one is more determinant in terms of RS effects on mobilization? If you have any thoughts (or any related topics) in this regard, feel free to shoot me a message and I am happy to discuss.
