The Regression Trap

Abstract

Building on Daniel Kahneman’s account of regression to the mean (including his flight-instructor case), Silvan Tomkins’ theory of discrete affect, Donald Nathanson’s Compass of Shame, and recent neurobiological work on the lateral habenula (LHb), the paper traces a mechanism by which externally imposed shame recruits anti-reward, dopamine-suppressing circuitry — redirecting the performer from problem-solving toward threat-monitoring and mistake-avoidance. It extends this analysis from the individual to institutional and pedagogical contexts, contrasting punitive evaluative architectures with low-inhibition, interest-driven models of instruction (Montessori, the Meno, Dweck’s growth mindset). The paper concludes that durable progress requires raising the underlying baseline rather than reacting to statistical peaks and troughs.
