A scientific controversy is a 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. For example, the connection between race and intelligence has been a subject of debate in both popular science and academic research since the inception of IQ testing in the early 20th century.
Controversies between scientific and non-scientific ideas are not within the realm of science and are not true scientific controversies.
