Self-Construction, Self-Protection, and Self-Enhancement: A Homeostatic Model of Identity Protection

Abstract

Abstract Self-protection and self-enhancement, once depicted as biases that impede accurate self-knowledge and hinder effective environmental control, have more recently been viewed as misbeliefs that can have fortuitous, adaptive consequences. I take the next step forward by construing identity protection and enhancement mechanisms as part of a routine, adaptive system. Whereas biological homeostasis regulates physiological processes, psychological homeostasis regulates the emotional states that threaten a desired identity. Ι elaborate on the nature of psychological homeostasis, the identity system that it modulates, and the immune system that safeguards it from harm. Ι discuss the construction of self-views and narratives in the ordinary stream of mental activity, as well as reparative responses to contemporaneous threats, similar to the immune system’s response to microbes that breach the body’s initial defenses. Using basic immunological principles, Ι distinguish between innate and adaptive psychological immunity, compare the spread of disease to that of threatening information among related self-views and narratives, and consider the “memories” of the biological and psychological immune systems to redress future threats. In addition, Ι offer a set of propositions that include predictions about various aspects of immunity, and end by considering the roles of awareness and self-deception in the immunity process.
