That doesn't stop anyone from perceiving bias, indeed obvious bias ("of course"). It's the instant reflex that every ideologically committed user experiences, but it's in the eye of the beholder. People's own views determine how they imagine HN's bias or mods' bias—not only which polarity they perceive, but how intensely they perceive it. If you tell me what bias you perceive in HN, I can tell you what your own politics are. This is perhaps the most reliable phenomenon we see on HN.
