TL;DR clickbait is addictive.

“And just as our brains like empty calories from junk food, they can overvalue information that makes us feel good but may not be useful—what some may call idle curiosity.”

THAT is the point of the article. Crap information is addictive.

I knew there was some sort of angle to this.

Are you saying you think their angle was to reach a conclusion that sugary information is addictive? It sounded like that was the starting point. What's the issue?

They didn't specify what kind of information in the header. So you could either assume ALL information is like junkfood and drugs, or you could assume people are filling up on information and becoming more intelligent (which I assume NO ONE assumed) or make any number of assumptions.

Case in point: the headline is too ambiguous.
