What exactly is “the data” that we’re talking about? Is it the measurements that were made, and the methodology used to make them? Or is it the conclusion that something in this case is a “myth”? Because I’d suggest that only one of those things is “the data”, and the other one is a subjective interpretation of it. I’d also suggest that people who have an agenda to promote will often attempt to blur the line as much as possible between empirical measurements, and their own opinions about what they’re supposed to mean.
