No, I would use them in very different ways. Antisocial behaviour is a common phrase especially since there is now an AntiSocial Behaviour Order or ASBO. To say someone is antisocial means that they don’t conform or follow society’s rules. To be introverted is a personality trait where you enjoy your own thoughts and are not so concerned with the thoughts or behaviour of others. So they are both to do with behaviour but are quite different

I am a Scot living in England

There’s a vast difference, introverted means a person is bashful or keeps themselves to themselves, antisocial means a person is hostile or even beligerent toward their community or society in general.

I am introverted. My cat is antisocial. We both live in the US.

I think of it as introverted being shy and enjoying one’s own company. Antisocial being strongly opposed to human interaction for any social reason.

You might use unsociable when talking about an introvert. I wouldn’t be offended if I was called introverted but I might if someone called me unsociable and I definitely would be offended if I was called anti-social

I don’t believe that is true of England.

No. I’m English and I don’t use those two words interchangeably. They have quite different meanings.

Okay, thanks guys.

I can’t even remember where I read it now, but I remember being baffled as to why that might be the case.
