Behavior-based safety processes are successful because they are based on direct observations of people doing their jobs. We don't have to know what people are thinking or understand their beliefs and attitudes. While beliefs and attitudes are surely important, we don't have direct access to them, so we can never truly understand what others think or believe. However, we can see what people do—the actions they take to ensure they are not injured and the actions they take that may put them at risk for injury.
