Spillover (experiment)

In the context of experimental research, "spillover" refers to the phenomenon where the effects of an intervention or treatment administered to one group in a study inadvertently influence another group that is not directly receiving the treatment. Spillover effects can occur in various fields, including economics, public health, and social sciences. For example: 1. **Public Health Experiments**: If a health intervention, such as a vaccination program, is implemented in a specific community, the benefits might extend to neighboring communities.
