Bias in, symbolic compliance out? GPT's reliance on gender and race in strategic evaluations

open access: yesStrategic Management Journal, EarlyView.
Abstract Research summary Organizations are increasingly using large language models (LLMs) to support strategic evaluations. We examine whether and how these systems rely on gender and race. We asked GPT to evaluate identical startup pitches varying only the founder's name, shaping gender and race perceptions.
