If you say a new study reiterating what we already know dressed up as a "new discovery" that sentence can be interpreted as you saying the new study is dressing up the discovery as something novel. I don't see why you needed to take a jab at my reading comprehension / character here, you could have just said, "I meant ... by this sentence not ..." and we'd be in agreement.

I read your comment as; first critiquing new studies trying to propose old discoveries as novel, and then going on to say you get annoyed at how the media or other people handle these studies and insert a lot of hyperbole.

I don't think this is an unfair interpretation, although if my reading comprehension has gone wrong somewhere, then explain where and how, because I evidently can't see where I've gone wrong (or I wouldn't have interpreted like so).
