My point is that voting determines what's relevant. Voting has put this on the front page. It's not about what you think, or whether you would argue that cognitive bias "is arguably more germane to HN", it has to do with what HN readers think is valuable and vote for.
the HN guidelines determine what should be submitted. The flag option exists in part because some HN readers submit or upvote stories that the guidelines say don't belong here.
