Scientific controversy
A scientific controversy is some form of substantial disagreement among scientists. A scientific controversy may involve issues such as the interpretation of data, which ideas are most supported by evidence, and which ideas are most worth pursuing. Controversies between scientific and non-scientific ideas are not within the realm of science and are not true scientific controversies.
