Did you read TFA? This exact phenomenon is discussed thoroughly in the post.
Should I only comment if I have a counterexample?
This passage comes to mind:
> we want so badly to be believed, to be seen as someone who knows stuff.
Some articles posted to HN have poor enough quality that reading a few paragraphs is all they deserve. The false premise is usually evident from the first paragraphs, and there's no reason to read further (unless it's one of those articles where the author changes their mind through a long exposition).
