Here's another weakness in all this analysis: The (presumed) value of the data and analysis. For years -- decades -- the medical professions have told us that "salt is bad". Now, we're finally learning that, specific and limited medical conditions or extreme diets aside, this is not so much the case. In fact, to little salt -- even when not "extremely" little -- may present significant problems. Imagine insurers having had purchase/dietary information available during this "salt is bad" phase. How much harm might their resulting "persuasion" have caused? (As a simplistic argument/point.) Taken to extreme, such controls are like "best practices". They can trend towards mono-cultures, which nature shows us tend to be fragile things. Humans need to understand that our population has diversity, that this is a good thing, and that, wedged together in our cities, towns, countries, and onto this blue marble, to some extent we are "all in it together". Like it or not. TL;DR: Some of these data analysis practices should spend more time worrying about their own garden. P.S. I'm not against analysis, in general in life. I am against biased analysis warped by self-serving motivations.
