This document discusses several concepts related to understanding human nature and behavior in organizational settings. It outlines two propositions: 1) that behavior is influenced by both individual and environmental factors, and 2) that behavior has a cause-and-effect relationship where a stimulus causes an individual's response. It then describes the Stimulus-Organism-Behavior (SOB) model, which shows how individuals receive and process stimuli, form responses based on their beliefs and attitudes, and may provide feedback on their actions. The document also discusses differences between individuals that influence behavior and the concept of bounded rationality, where perfect rationality is impossible due to human cognitive limitations.
