Social Media + Society
forthcoming
The rise of generative artificial intelligence (AI), particularly advanced AI chatbots such as ChatGPT, has transformed human-AI interactions by providing unprecedentedly natural interaction environments. These developments have significantly heightened user perceptions of AI as human-like, making anthropomorphism, a tendency to attribute human traits to non-humans, increasingly prevalent. Despite the recognition of the rising anthropomorphism in these interaction modalities, little is known about how people anthropomorphize generative AI, especially in social media discourse. Using Twitter/X as a discursive space, we systematically analyze how users described and engaged with ChatGPT, identifying distinct categories and recurring forms of anthropomorphism. Findings reveal diverse anthropomorphic perceptions, including personification, emotional attributions, cognitive and human-like attributes, social interactions, and human-like personality traits. Building on the observation that social media platforms not only reflect but also actively shape and reinforce anthropomorphic narratives, this study raises important implications for trust, misinformation, user expectations, and human-AI interactions.
