> who decide to go to a new group social event to change things up will struggle to make a connection with someone else

I can't imagine going to a general "group social event" like a party and making a connection. I'd end up just sitting there being bored until I left. I don't have the personality to just strike up a conversation about nothing with some one I don't know. But I do somewhat often go to events that revolve around my hobbies. There, I already have a connection with the strangers, through the hobby, and I have something to talk about or listen to. I've met plenty of new friends that way.
