Background: Taylor Swift has cultivated one of the most engaged pop fandoms by embedding cryptic Easter Eggs throughout her work, transforming her music and public appearances into a puzzle for fans to solve. Platforms like Reddit and TikTok enable this collective decoding process, where fans propose, support, or reject interpretations in a shared effort to make sense of her hidden messages. This collaborative meaning-making plays a crucial role in shaping which interpretations rise to dominance and become part of the broader narrative – a dynamic that has also become a powerful marketing strategy for Taylor Swift’s brand.

Research Problem: In today’s digital landscape, fans are no longer passive consumers but active participants in the creation and interpretation of cultural texts. Social media platforms amplify this participatory culture, enabling fans to collectively analyze, debate, and circulate their interpretations. This is particularly visible in fandoms like Taylor Swift’s, where ambiguous messages such as Easter Eggs encourage collaborative meaning-making. While prior research has explored the role of producers and the strategic use of Easter Eggs for branding, there remains a lack of detailed understanding of how fan practices drive this interpretive process, and how individual interpretations converge into dominant readings that become embedded in the fan lore.

Research Purpose: The purpose of this study is to identify the underlying causal mechanisms through which fans collaboratively interpret, construct, and negotiate the meaning of Easter Eggs within Taylor Swift’s fandom. Additionally, it aims to highlight how these mechanisms contribute to the emergence of dominant interpretations and the development of collective fan knowledge.

Research Question: What causal mechanisms contribute to the emergence and dominance of certain interpretations of Taylor Swift’s polysemic Easter Eggs within her fan community?

Research Method: This study adopts a qualitative, inductive research approach grounded in critical realism and post-positivist epistemology. It uses a single-case, explaining-outcome process tracing design to identify causal mechanisms behind collective meaning-making in Taylor Swift’s fandom. Data are collected through netnography from Reddit and analyzed to trace how fan interpretations emerge, evolve, and become dominant.

Conclusion: The results of our research show that fan communities engage in a six-stage meaning-making process through which multiple dominant interpretations gradually emerge, and ultimately, one is accepted into the fan canon. This process is structured, knowledge-driven, and characterized by the collective efforts to reach consensus. We identified 19 causal mechanisms that drive this process from noticing a potential Easter Egg to the confirmation of a dominant interpretation and the start of a new meaning-making cycle. These mechanisms demonstrate how fans collectively notice, debate, refine, and validate interpretations. They fulfill four functions that drive the process towards consensus. The relevance of each function shifts with the progression of the meaning-making stages.
