BI-CST: Behavioral Science-based Creativity Support Tool for Overcoming Design Fixation.

Design Fixation refers to the tendency to adhere to pre-existing ideas, which hinders innovative design solutions. This research explores the potential of LLM-powered Creativity Support Tools, the 'Behaviorally Informed Creativity Support Tool (BI-CST),' to facilitate ideation and combat Design Fixation using 'Behavioral Science Theory.' BI-CST assists in redefining problems and generating new ideas by presenting experimental findings from Behavioral Sciences that challenge users' initial concepts, thus providing a deeper understanding of real human behaviors. We will assign three groups to different conditions: one designing without generative AI support, one with open-ended generative AI (e.g., ChatGPT), and one using a model trained in behavioral science. We aim to compare the originality, practicality, and general quality of the designs to assess design fixation. This study addresses design fixation through an interdisciplinary approach combining design and behavioral science, aiming to expand users' perspectives.
