Haha, very well said. Warning: bit of a long comment coming --
It seems like a weekly thing. And such things don't stop with dark matter or the field of physics. It's most things. "Blank blank may blank your blank". It's always this level of uncertainty that can allow pretty much any claim to be made in an article. And if definitive proof ever comes out, they're covered because they can point to the article and say "We said 'might' or 'may' or 'could'". A funny example is the endless "stories"/studies of coffee/wine/chocolate and whether they "may be better or worse for you than we once thought". "This doctor says blah blah blah" or "a study suggests yada yada yada". Looking into the study(ies) is a good move. I mean pick a field: physics, psychology, nutrition, etc. Those are some major ones.
That said, I'm not trying to diminish the great work that is often done, the benefits and implications of that work, and how much the cutting edge of physics excites me. I suppose, to put it in broad/general/simple terms, it's that these organizations get set up in order to bring us the latest goings on and have to put out a certain amount of material in a certain timeframe. When there isn't really enough new things to put out, they still put things out and are forced to write about whatever they can find in vague terms so as to not publish false information and ruin their credibility. They need to stay profitable so they won't just release a few good articles over a week and say, "Sorry, folks. That's all that's really happened lately." And they make the article titles as intriguing as possible while staying within the realm of truth-telling even if it is vague. "Dark Matter could be more complex than we once thought" -- "Ah, what complexities?", you might ask yourself. "I did have some thoughts about dark matter...what's new?" click But, most of the time, one leaves the article with more questions than answers...the curiosity that was piqued most times goes unsatisfied.
Anyway, those are some of my thoughts on the matter topic. I should mention that I'm not a physics student of graduate (went for engineering) so maybe someone will come along and rip me a new one.
