Natural experiments are observations of variables that aren't subject to manipulation. They are common in epidemiology research and social science. However, the results of natural experiments do not always provide conclusive evidence. It is not always easy to use natural experimentation to evaluate the effects on non-health intervention. However, natural experiments are valuable tools for assessing the health impact of interventions.
A natural experiment involves observing a phenomenon and conducting a comparative study of the conditions that surround the observation. It is essential to define the exposure in order for meaningful data to be produced. If exposure isn't defined, it can be difficult or impossible to identify whether the observed outcomes result from the exposure.
Natural experiments are most frequently used in epidemiology and social science. The best natural experiments are those which mimic the conditions of a controlled experiment. This allows the investigator to examine the relationship between the exposure and the outcomes. A control group is defined as a population that is either exposed to or not exposed to a particular condition. Complex designs are common in natural experiments. They are more effective when the exposure is well-defined and clear.
Natural experiments, unlike the controlled observational study that is conducted by researchers, do not use random assignment. Natural experiments are governed by nature and other factors. Researchers can't manipulate 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. This allows researchers to see a change in water color. It is possible to also observe the color changes in water by placing a marble in a pond. However, the marble's color can also change due to changes in water levels and a change in the amount of time it spends in the pond.
A natural experiment on an isolated island in Caribbean can be used to draw inferences about evolutionary history. However, in this case, it is important to remember that natural experiments do not provide conclusive evidence of causation. There are also many risks to a natural experiment, such as lack of random assignment. This can lead to multiple threats to the validity 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. This is because the study cannot be based on an accurate estimate of the exposure of each individual. In London, England during a cholera crisis, 127 people were killed in three days. The outbreak was traced to the nearest public water pump. A map showing deaths and illnesses helped to identify the exact location.
