Why does information have to be immediately actionable? What happened to being generally informed and educated? Jefferson also said:

Celebrity gossip is attention spam, but terrorism and war seem extremely relevant to tax-paying citizens. The corresponding philosophical and ethical questions are also important to consider and debate, those discussions are what change our nation's policies (not elections).
I'll grant that cable news is largely fluff... "President tweets" turns into 8 hours of rehashing the same narrative with a dozen "correspondents" while ignoring the power grab by Venezuela's constituent assembly (interesting parallels in Turkey, and the US) or the progress of different legislation in Congress... but, low quality news still falls in a different category than the endless mindless Snaps and Imgur memes.
Dobelli is talking about that low-quality media: infotainment. The processing, sanitization, and refinement of news into bite-sized dopamine triggers. Hollow snippets that only serve to feed the Dunning–Kruger effect... magnified by commenting and social media, the worst of the worst.
My approach is just to cap the time spent on news. 2x 30 minutes a day I'll dedicate myself to reading news from reputable news agencies, often with a paid subscription, otherwise I just completely ignore news.
