Why we cite it

Introduces the concept of explanatory style — how people explain bad events to themselves across three dimensions (permanence, pervasiveness, personalization) — and demonstrates that optimism is a learnable skill rather than a fixed trait. Provides the ABCDE cognitive framework for disputing pessimistic thinking, directly applicable to reframing diet and behavior-change setbacks.
