Quizplus · Accepted Answer

A natural experiment involves observing what happens under naturally occurring conditions, rather than manipulating or controlling variables. This allows researchers to investigate the effects of a naturally occurring event or circumstance on a particular outcome. Examples of natural experiments may include studying the effects of a policy implemented in one region but not in another, or studying the impact of a natural disaster on mental health outcomes. Self-selection (A) and random assignment (C) are techniques used in experimental designs, not natural experiments. (D) is irrelevant to the definition of a natural experiment.
