All of Residency's a Stage: Fostering Authenticity and Individuality Among Learners.

Understanding the process of professional identity formation, and its susceptibility to the hidden curriculum, is of increasing importance in medical education. Through a lens of performance, this commentary explores the impact of the culture, the hidden curriculum, and the socialization process of the medical training environment on the professional identity formation of learners. We emphasize the need to train physicians with diverse interests and skills, capable of creative problem solving in response to the rapidly evolving challenges facing the profession and society more broadly. Opportunities for learners to drive cultural change and promote authenticity and unique professional identity formation are identified.
