So it sounds like you're arguing linkbait is fine because we all have internalized some general skepticism to fight it. But actually I don't think that's the best approach. For one it takes more cognitive overhead to scan through 40 links and then play the mental "what will I actually get if I click this link?" 40 times.
For the most part HN is great about not having linkbait. But when I do see something that sounds improbably good I just go straight to the comments and see if other people find the article legit (as is the case here).
