Natural experiments
Natural experiments are observational studies where researchers take advantage of real-world events or situations to analyze their effects on specific outcomes, without manipulating variables themselves. For example, if a new law is passed in one region but not another, researchers can compare the two areas to assess the law's impact. This method allows scientists to explore cause-and-effect relationships in situations that mimic controlled experiments, although they occur naturally. Natural experiments are valuable for studying social, economic, or health-related phenomena where controlled experiments are not feasible or ethical.

Natural experiments occur when researchers observe real-world events or changes that affect people in different ways, allowing them to study the effects of those changes without manipulating any variables themselves. For example, if a new law is passed in one region but not in another, researchers can compare the outcomes in both areas to understand the law's impact. These situations arise naturally, hence the name “natural experiments,” and they help scientists draw conclusions about cause and effect in complex social or environmental settings.
