Just guessing based off body language, more oomph in their voice, more aggression on the court afterwards. They could be really good at masking though. Or team sports might filter out super introverts (assuming there’s a spectrum).
A lot of companies aren’t optimized for introverts. Besides the low talk, alimcforever probably doesn’t like team meetings in general (I think most people hate meetings but that’s a separate topic). DHH, the Ruby on Rails creator, talks about how much meetings suck. He structured his companies in a way that’s better for introverts, partly because I don’t think he likes the social BS either.
Speaking of social being context specific, I don’t know much about small talk in the UK. I’ve heard there’s a lot of class based status stuff that still lingers. I don’t think that is quite the same as what we deal with in the US.
