The “mad genius” stereotype—that exceptional creativity is intrinsically linked to mental illness—persists in both public imagination and scholarly discourse, despite growing empirical evidence to the contrary. This article synthesizes contemporary research on the creativity–mental health debate, structured around five dimensions: (1) creativity level (mini-c, little-c, Pro-c, Big-C); (2) domain; (3) personality traits; (4) assessment method; and (5) type and severity of mental health issues. Using this nuanced framework, this chapter offers a more accurate understanding. It appears that elevated rates of mental illness occur more commonly among eminent (Big-C) creators, particularly in artistic domains. The majority of creative individuals, however, display little to no psychopathology and do not have psychological disorders which tend to obstruct creativity at higher clinical levels. In fact, recent literature finds that most everyday and professional creators (little-c and Pro-c) experience positive associations between creative engagement and several variables associated with well-being.
