Briefly explain the concept of Situationism as outlined in the study of ethical systems.
The study of ethical systems treats the concept of Situationism typically as an ethically oriented theory that holds that changes in human behavior are exclusively caused by situational factors and not traits of an individual. Situationism acknowledges the role of external factors in influencing behavior while holding that internal motivations or traits do not impact an individual's behavior. Aspects such as experience, thoughts, dispositions, and feelings do not determine the course of action taken by an individual depending on the circumstances. Instead, the course of action is subject to the situation at hand.
