Chronic Underachievement as Capacity-Suppression Wrong Attractor: The Invisible Ceiling, Threat-Avoidance Architecture, and the Return to Expressed Potential

Chronic underachievement — the sustained pattern of performing significantly below one's demonstrated or estimated capacity, driven by threat-avoidance rather than genuine preference — is here formally reconceptualized as a wrong attractor W_CU in the landscape of expressed potential. The healthy ground state S^0 is defined as expressed potential: the capacity to perform near the upper range of one's genuine abilities without unconscious suppression.

W_CU is distinguished from self-sabotage, which involves actively disrupting progress at threshold moments; underachievement is the more pervasive baseline suppression — the person never approaches their ceiling. Two basin variants are characterized: threat-avoidance underachievement (success threatens the existing identity structure, so performance is suppressed below the threatening threshold) and effort-protection underachievement (never trying fully preserves the fiction of untapped potential, insulating self-concept from genuine failure).

Nine formal propositions characterize the invisible ceiling, the performance-capacity gap, basin deepening through gifted-student dynamics and perfectionism, the distinction from genuine limits and deliberate life prioritization, and return paths through growth mindset work, effort exposure, and schema therapy.
