Often used in the social sciences and epidemiology, natural experiments are observational studies that do not involve artificial manipulation of variables. The results of natural experiments may not always be conclusive. Natural experiments can prove difficult to use in studies of the non-health effects of interventions. Natural experiments are great tools for assessing health effects of interventions.
Natural experiments involve observing a phenomenon, and then comparing the conditions surrounding it. The exposure must be clearly defined in order to generate meaningful data. If the exposure is not known, it can prove difficult to determine whether the observed results are the result of the exposure.
The most common applications of natural experiments are in epidemiology, social science, and political science. The most useful natural experiment are those that replicate the experience of a control subject in a controlled study. This allows the investigators to analyze the relationship between exposures and outcomes. A control group is a population that is not or is exposed to a specific condition. Many natural experiments have complicated 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 have conditions that are set by nature or other factors. Researchers cannot manipulate the participants' exposure.
One example is when a leaf becomes trapped in rock. This leaves an impression in rock. Over thousands of years, the leaf dies and decays, but the impression in the rock remains. The researcher can observe the water's color change. The marble can also be placed in a pond to monitor the water's color. The marble's colour can also be affected by changes in water levels and the amount of time it is in the pond.
When a natural experiment is carried out on an isolated island in the Caribbean, it is possible to make inferences about evolutionary history without laboratory manipulation. In this case, however, it is important that you remember that natural experiments cannot provide conclusive evidence to prove causation. A natural experiment has many potential risks. For example, a lack of random assignment can lead to unintended consequences. This could lead to numerous threats to the validity and integrity of the study.
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. The study cannot be based upon an accurate estimate of each person's exposure. Three days ago, 127 people succumbed to cholera in London, England. The outbreak was traced to the nearest pump. An illness map was used to determine the location of this outbreak.
