Natural experiments are observations that are not subject to artificial manipulation. These types of studies are commonly used in epidemiology or the social sciences. Natural experiments can provide inconsistent evidence. 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.
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. If the exposure is not known, it can prove difficult to determine whether the observed results are the result of the exposure.

Natural experiments are used most often in social science, epidemiology, and politics. 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 refers to a group that is either not exposed or exposed to a given condition. Natural experiments can often be complex. They are more effective when the exposure is well-defined and clear.
Natural experiments do not have random assignment unlike the controlled observational research, which is designed by researchers. The conditions in a natural experiment are determined by nature or other factors. Researchers cannot manipulate the participants' exposure.
For example, when a leaf is trapped in a rock, it leaves an impression in the rock. Over thousands of decades, the impression that the leaf left in the rock is not only preserved, but also dies. This allows the researcher the opportunity to observe a shift in the color of water. Similarly, when a marble is placed in a pond, it can be used to observe the color of the water. However, marble's colors can change due to changes of water levels or the time spent in the pond.
If a natural experiment is done on an isolated island off the Caribbean, it's possible to draw inferences about evolution without manipulating laboratory data. It is important to note that natural experiments don't provide conclusive evidence for causation. Natural experiments can also be subject to risks such as a lack random assignment. This could result in multiple threats to study validity.

It can also be difficult to determine if exposure is responsible for observed outcomes when natural experiments are conducted on a large population. Because each person's exposure cannot be accurately estimated, the study can't be done. Three days ago, 127 people succumbed to cholera in London, England. The outbreak was tracked to the nearest water pump. A map showing deaths and illnesses helped to identify the exact location.
