Natural experiments are observations that are not subject to artificial manipulation. These types of studies are commonly used in epidemiology or the social sciences. 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 is when you observe a phenomenon and compare the conditions surrounding it. To produce meaningful data, exposure must be identified. When exposure is not defined, it can be difficult to know whether the observed outcomes are a result of the exposure or the exposure itself.
Natural experiments are most commonly used in the fields of epidemiology, political science, and social science. Natural experiments that simulate the presence of a control group during controlled experiments are the most valuable. This allows the investigators examine the relationship between the outcome and exposure. A control group is a population that is not or is exposed to a specific condition. Natural experiments are often complex. These experiments are more efficient if the exposure is clearly defined.
Natural experiments don't involve random assignment, unlike controlled observational studies that are designed by researchers. Natural experiments can only be conducted under conditions determined by nature, or other factors. Researchers are not allowed to manipulate the participants' exposure.
If a leaf is caught in a rock, it makes an impression. The impression is kept in the rock for thousands of year. Although the leaf eventually falls away, it will still leave an impression. This allows the researcher observe a change of color in the water. Similar to the above, a marble placed in a water pond can be used for observing the color of the water. However, marble's colors can change due to changes of water levels or the time spent 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. Natural experiments can also be subject to risks such as a lack random assignment. This could result in multiple threats to study validity.
Similar results can be obtained when a natural experiment is conducted on a population. It can be difficult, however, to determine whether the exposure resulted in the observed outcomes. 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 tracked to the nearest water pump. A map of deaths and illnesses was used to pinpoint the location of the outbreak.
