I don't see the irony - the Myers-Brigg test pegged me as an extrovert, I did not insinuate that this has any relevance to anything whatsoever - quite the opposite.
The point is that most of HN identifies themselves - on the Myers-Briggs scale anyway - as introverts. The test labels me an extrovert, yet I do not see these artificial, and frankly invented, differences between all of us.
I also mentioned that this sort of broad labeling is divisive - and I certainly feel this way. I've been labeled as a Myers-Brigg extrovert, and now I have the rest of HN to thank for assuming that I'm a brash, shoot-first-ask-questions-later sort of guy.
The differences aren't invented. I see them every day within my own family. My Dad literally argues with himself out loud. I used to think he was arguing with me, but he's not, because now I just remain silent and the argument still happens. He's not being brash, and he's not shooting first. He's just figuring out the problem with his own method. And when he's done, he's usually right (warning: son idolising father bias).
I don't see the problem labeling my Dad an extrovert... there's nothing negative about it, and it describes one general aspect of his personality pretty well. Even more so, recognising this aspect of his personality has helped me interact with him in a much more productive manner.
I think before I speak - and I certainly do not use out-loud speech as my reasoning playground. Broad brushes like these really should be avoided.
