I suppose the large downside isn’t ignorance or malice however reasonably the expectation that they give you a definitive conclusion.
Additionally, I believe Lakeland is a bit unfair to the information media.

The New York Occasions has Moderate Drinking Has No Health Benefits, Analysis of Decades of Research Finds. I can’t discover something saying that average consuming is dangerous for you.

However none of them led with, “Newest observational research reveals average consuming related to a really barely decrease mortality fee,” which might be a extra correct abstract of the research.
In any case, it’s arduous to be taught a lot from this kind of small distinction in an observational research. There are simply too many different potential biases floating round.
I believe the background right here is that alcohol habit causes all kinds of issues, and so public well being authorities wish to discourage folks from consuming. Even when average consuming is related to a 7% decrease mortality fee, there’s a priority {that a} public message that consuming is useful will result in extra alcoholism and ruined lives. With the information media the problem is extra difficult, as a result of they’re torn between deference to the science institution on one facet, and the will for splashy headlines on the opposite. “Massive research finds that average consuming saves lives” is a greater headline than “Massive research finds that average consuming doesn’t save lives.” The message that alcohol is nice for you is counterintuitive and likewise crowd-pleasing, no less than to the drinkers within the viewers. So I’m kinda stunned that no journalistic retailers took this tack. I’m guessing that not too many journalists learn previous the summary.
