Sure, well I didn't mean to imply to only read headlines; definitely dig in on stuff that seems worthy of interest.
Also, that's exactly why I added the clause "or may not be there" :) That's part of the skill when reading headlines - training to see it as a dirty filter and seeing if there are any glints in the dirt that are interesting enough to follow up on.
point taken, however
It's a common practice to lie[0] in a headline, then correct it in the article. This makes headlines have negative informational value - you're literally more wrong about the world after scrolling quickly through a news page than you would be if you didn't.
