Also you will get scolded in a meaningful way if you screw up or say really dumb things with no evidence here.
HN used to have a general rule in the community that you don't downvote without explaining why. It was a much nicer place back then.
That's just tech in general. Or business. Anything that deals in hard facts. Hand waving bullshit without evidence or at least, validity in reasoning - that's just bad long term.
Of course the real truth though is no one can know everything. To me, that implies there's a limit where people say 'this is the line we stop thinking at, when we hit this line'. I'm curious to know whether the belief that the line exists there to begin with is there because it retains some tolerable amount of bullshit, or because some people just really aren't used to actually being aware of their own occasional idiocy.
I dunno. I don't think it's a positive long term to make people feel dumb. Probably something that gets retained because it just works, an evolutionary heuristic, not necessarily one planned for, designed, selected.
Which.. (the universe truly does have a divine sense of humor) - intelligence can literally be stupidity. Therefore, it doesn't mean whatever intelligence designates most intelligent is actually the most effective way of getting to the truth, or defining the best way to do things. Just means, it's the way things get done, until a better way is revealed or found.
