A scientific controversy may be a fundamental disagreement among scientists about the validity of a major theory, a secondary scientific controversy, i.e., "scientists disagreeing about a less central aspect of a scientific idea."[1]

A true scientific controversy involves a sustained debate within the broader scientific community (McMullin, 1987[2]). In other words, a significant number of people must be actively engaged in research that addresses the controversy over time.[3]

True scientific controversy ... is healthy and involves disagreements over how data should be interpreted, over which ideas are best supported by the available evidence, and over which ideas are worth investigating further.[1]

Anne E. Egger said, "Controversies cause progress in science by encouraging research on the topic in question."[3]
