This document discusses how perceptions, beliefs, and attitudes can impact organizational behavior. It explores stereotyping, self-fulfilling prophecies, and biases like the halo effect. It also examines entity versus incremental theories of human traits, and how self-efficacy, self-esteem, narcissism, and perceptions of independence versus interdependence can influence self-views and behavior. Managers are advised to recognize how their own biases and assumptions may affect their judgments of others.
