be unreasonable

NBC reports (here http://www.nbcnews.com/storyline/zika-vi...) that news stories that are calm and accurate are less popular than inaccurate but loud stories, particularly if those stories predict disaster.

So if you want your story to catch some attention, include end-of-the-world predictions and be aggressive and loud.

Probably it helps to blame someone. Who to blame? I would tend to pick dark nefarious groups that can't be found, because hey, they won't defend themselves. But others will do, "the elite", or "the scientists", or "the mass media".
