Why we cite it
The foundational theoretical paper for Identity-Based Motivation (IBM) — the formal psychological theory explaining why identity-congruent behavior feels automatic while identity-incongruent behavior feels effortful. Provides the theoretical mechanism underlying the practical findings in cib02 (Patrick's "I don't" vs "I can't") and cib01 (Verplanken's habit-identity link): when an identity is salient, action-readiness and procedural-readiness are cued without conscious processing, making congruent choices feel natural rather than requiring willpower. From a ~49k-citation researcher who developed this entire framework.
