I personally would argue that the HN community does a good job at applying the scientific method and question unsupported conclusions.

I don't think it's about believing which side is right. Many subjective topics aren't popular on HN because there's no way to reach a census. I have also noticed that most comments don't engage with exaggerated and flame bait language. People are generally listened to and responded to respectfully. There's going to be exceptions, but I see less troll type comments on HN and that's why I respect it as a source.

The "nutjob wacko" opinions are respectfully heard and then respectfully torn apart.
