This document discusses attribution theory and how people explain their own behaviors. It provides two main theories for why people make attributions: 1) learning to infer that voluntary behaviors indicate enjoyment or preference, and 2) assuming one likes all voluntary behaviors. There are two types of attributions: external/sufficient justification attributes behaviors to outside factors, while internal/insufficient justification assumes behaviors were done willingly. Internal attributions can lead to consistency in future behaviors, while external attributions may not predict consistency unless the external factors remain present. Research on cognitive dissonance and persuasion techniques also found that internal attributions relieve dissonance more and can create commitment to behaviors.
