See, you put the caveat at the bottom, but I think you are just having a normal discussion. You aren't speaking "very confidently," you are just making an argument.

What I think happens is people who are very knowledgeable about a subject are hyper-sensitive to slightly incorrect information. And to boost their egos they like to diminish the people making the incorrect statements as not just incorrect, but confidently incorrect, a la Dunning Kruger.

See how confidently I made the exaggerative statement above? I don't necessarily mean it to be completely true, but I am making an argument. I think an assessment of confidence requires more than seeing no mollifying qualifiers like "I think" or "it might be". There's no verbal tone on the web.

It was a little meta-joke, but I think the world could use a lot more expressions of doubt. Very few things are certain or universally true, and those that do tend to have Greek letters in them. I find highly confident people highly suspicious, and a culture that rewards overconfidence and punishes doubt both exhausting and dangerous.
