Question: Why does voluntary participation conflict with the goal of generalizability? Need Assignment Help? Volunteers usually provide incorrect information. This interferes with the need to collect accurate information, which is a key tenet of scientific inquiry. It doesn't. Responses from non-volunteers are very similar to those from research volunteers. A researcher cannot generalize the sample survey findings to an entire population unless a substantial majority of the sample actually participates. A researcher is required to pay subjects for their time under the fourth law of generalizability.
