I posted earlier how HN is highly susceptible to both groupthink as well as confirmation bias [1]. Check yourself and ask yourself if what is posted is actually true or is rather something you WISH was true, and also if what is posted is something that you would prefer to go with the herd than to try to run against the stampede. But humans are humans.
