Self-tolerance is an academic concept in psychology referring to an individual's capacity to internally manage or accept challenging psychological states, difficult experiences, or perceived shortcomings related to the self. This concept investigates the mechanisms, boundaries, and consequences of this internal capacity, recognizing that it operates within a functional range beyond which it may become detrimental. The significance of self-tolerance lies in its relevance to psychological resilience, emotional regulation, and clinical interventions aimed at fostering self-acceptance and adaptive coping strategies.
