  This paper investigates the potential of LLM-based conversational agents
(CAs) to enhance critical reflection and mitigate design fixation in group
design work. By challenging AI-generated recommendations and prevailing group
opinions, these agents address issues such as groupthink and promote a more
dynamic and inclusive design process. Key design considerations include
optimizing intervention timing, ensuring clarity in counterarguments, and
balancing critical thinking with designers' satisfaction. CAs can also adapt to
various roles, supporting individual and collective reflection. Our work aligns
with the "Death of the Design Researcher?" workshop's goals, emphasizing the
transformative potential of generative AI in reshaping design practices and
promoting ethical considerations. By exploring innovative uses of generative AI
in group design contexts, we aim to stimulate discussion and open new pathways
for future research and development, ultimately contributing to practical tools
and resources for design researchers.
