This document discusses attribution theory and types of attribution errors people make. It explains that attribution is making guesses about the causes of events or behaviors. However, these guesses are often incorrect due to systematic biases. Two major biases discussed are the fundamental attribution error, where people attribute others' behaviors to internal factors rather than external influences, and self-serving bias, where people attribute their successes to internal factors and failures to external factors. The document also provides an overview of organizational behavior, noting it involves studying individuals, groups, and organizational levels and drawing from various fields like psychology and sociology.
