Does My Chatbot Have an Agenda? Understanding Human and AI Agency in Human-Human-like Chatbot Interaction

Bhada Yun , Evgenia Taranova , April Yi Wang

This is a solid CHI honorable-mention style contribution: not a flashy system, but a careful longitudinal study that turns agency into a relational, observable phenomenon and backs that claim with a distinctive progressive-transparency method. The main value is conceptual and methodological rather than technical.

Review Summary

This paper’s strongest contribution is that it does not treat agency in chatbot interaction as a binary property of either the user or the model. Instead, it builds a longitudinal, interview-rich account of how agency is negotiated across repeated exchanges, and it pairs that account with a concrete methodological move: the progressive transparency interview and strategy reveal. That combination matters because it lets the authors examine not just what participants say about control, but how their interpretations shift when the system’s goals are disclosed after the fact. The resulting 3-by-4 framework is a useful organizing device for HCI, especially because it distinguishes actors (Human, AI, Hybrid) from action types (Intention, Execution, Adaptation, Delimitation) and explicitly acknowledges contextual modulation. The evidence base is credible for the claims being made: a month-long study with 22 adults, roughly 75 hours and 192 sessions, plus interviews and cross-participant review, is enough to support a rich qualitative argument. At the same time, the paper is appropriately bounded. It does not establish universal laws of agency, and it cannot separate all system-independent dynamics from the specific design of 'Day.' The limitations section is important here: the authors acknowledge that they captured initial negotiations rather than long-term evolution, that the sample may not reflect broader cultural conceptions of agency, and that the research setting may shape behavior. So the paper is best read as a strong empirical and methodological contribution to the study of human-AI agency, with moderate overclaim risk only if readers try to generalize the framework beyond the studied context without further comparative work.

What Changed

Canon before

Prior CHI work on chatbot agency and transparency typically treats agency as attributable to either the human user or the system, and transparency as a general explanation or disclosure mechanism rather than a staged intervention for probing agency attribution.

Departure from common sense

The paper argues that agency in human-AI chatrooms is not a property owned by one side; instead, it is negotiated turn by turn and can be co-constructed across repeated interaction. That framing departs from the common-sense split between a controlling user and a passive tool.

Actual novelty

The methodological novelty is the progressive transparency interview, especially the strategy reveal that discloses the chatbot’s goals and internal profiles after interaction. This is used to probe how transparency changes agency attribution, rather than merely to explain the system.

Evidence

Evidence comes from a month-long longitudinal study with 22 adults, about 75 hours and 192 sessions of interaction with a single LLM companion, followed by interviews, post-hoc elicitation, cross-participant chat reviews, and a strategy reveal. The paper also states explicit limitations about ecological validity, sample diversity, and system-specificity.

“ Following the conversational phase, participants engaged in a 40-minute interview designed to progressively reveal “Day’s” internal workings while observing how transparency affected agency percep”

Limits

Method limits

The study captures initial agency negotiations in one chatbot setting, but not long-term evolution of agency over extended use. The design is qualitative and interpretive, so the framework is grounded in participant accounts and researcher analysis rather than causal isolation of mechanisms.

Deployment limits

Findings are tied to one LLM companion design and one research context; different architectures, transparency levels, or personality parameters may produce different agency patterns. The translucent design implication is therefore best read as a design direction, not a universally validated deployment recipe.

Boundary conditions

The results are bounded by a month-long study, 22 adult participants, and a single system ('Day'). The paper itself notes that the research setting may influence ecological validity and that comparative data across systems would be needed to separate general dynamics from system-specific artifacts.

Position in field

This paper contributes a qualitative, longitudinal account of agency in chatbot interaction and a new 3-by-4 framework for describing human, AI, and hybrid agency actions. Its main field value is reframing agency as relational and staged, while offering a transparency intervention that can be reused in future HCI studies.
