The Expert Myth: Impostor Phenomenon And Research Identity In Counselor Education, Kristi B. Cannon, Kelly Coker, Trent Hepting, Lidian Ramirez-Fiol, Robyn T. Simmons

Journal of Counselor Preparation and Supervision

Imposter Phenomenon (IP) affects counselor educators across career stages, yet it is often conceptualized as an individual deficiency rather than a systemically reinforced experience. This article frames IP in counselor education through the lens of the Expert Myth—a systemic pattern within academic culture that reinforces the expectation that faculty must consistently present as fully knowledgeable, productive, and self-assured to be regarded as credible. We examine how institutional cultures, publish-or-perish pressures, and inadequate mentorship structures create and reinforce imposter feelings, particularly among marginalized faculty and those navigating researcher identity development. Drawing on existing literature, we propose that meaningful intervention requires systemic …
