Often used in the social sciences and epidemiology, natural experiments are observational studies that do not involve artificial manipulation of variables. Natural experiments can provide inconsistent evidence. It can be difficult, for example, to use natural experiments to examine the effects of nonhealth interventions. Natural experiments are useful tools to assess the health effects of interventions.
A natural experiment is when you observe a phenomenon and compare the conditions surrounding it. The exposure must be clearly defined in order to generate meaningful data. It can be difficult to determine if the observed outcomes are the result of exposure or exposure.
The most common applications of natural experiments are in epidemiology, social science, and political science. The best natural experiments are those which mimic the conditions of a controlled experiment. This allows the investigators to analyze the relationship between exposures and outcomes. A control group is defined by a population that is either unaffected or affected by a condition. Natural experiments often have complex designs. They are often more successful if the exposure is clear and defined.
Natural experiments do not have random assignment unlike the controlled observational research, which is designed by researchers. Natural experiments are governed by nature and other factors. Researchers can't manipulate participants' exposure.
A leaf trapped in a rock can leave an impression on the rock. The impression is preserved in the rock even though the leaf eventually dies. This allows the researcher observe a change of color in the water. The marble can also be placed in a pond to monitor the water's color. The marble's color may change depending on the water level and how long it stays in the pond.
Natural experiments on isolated islands in the Caribbean are able to draw inferences about evolutionary past without the need for laboratory manipulation. Natural experiments are not conclusive evidence that causation exists in this instance. There are also many risks to a natural experiment, such as lack of random assignment. This could result in multiple threats to study validity.
Similar to the previous example, when an experiment is done on a group of people it can be difficult for them to know if the exposure was responsible. This is because the study cannot be based on an accurate estimate of the exposure of each individual. 127 people died during a cholera epidemic in London, England in three days. The outbreak was traced to the nearest pump. A map of deaths and illnesses was used to pinpoint the location of the outbreak.
