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. Natural experiments can prove difficult to use in studies of the non-health effects of interventions. Natural experiments can be a valuable tool for assessing the impact of interventions on health.
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 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 most useful natural experiments are those that mimic the presence of a control group in a controlled experiment. This allows the investigators examine the relationship between the outcome and exposure. A control group can be defined as a population that has been either exposed or not to a condition. Many natural experiments have complicated designs. They are often more effective if the exposure is defined and clearly 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. However, the exposure of the participants is not manipulated by the researchers.
If a leaf is caught in a rock, it makes an impression. 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 color may change depending on the water level and how long it stays 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. But, natural experiments can't prove causality. A natural experiment has many potential risks. For example, a lack of random assignment can lead to unintended consequences. This can pose multiple risks to the validity of the research.
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. 127 people died during a cholera epidemic in London, England in three days. The outbreak was traced to the nearest pump. A map showing deaths and illnesses helped to identify the exact location.
