ENTP: Great at improvised arguments, will definitely win if the other side hasn't planned everything out in advance. They know they are winners, and everyone else does too. Since it is rare that anyone ever plans things out down tot he last detail, I assume these guys are pretty much killers when it comes to arguments.
INTP: Epic fail, if God for bid, they are not irrefutably right about something. They will, however, think that they have won in 99 out of a 100 situations.
INTJ: They often win if they care enough about something (=has lots of knowledge about it). Never, ever debate science things with these guys. Ever. I mean, just don't!

Just nod quietly and let them do their thing.
ENTJ: Will win if they have things planned out. They know they have won and when they have lost, and everyone else does too. We usually mean business, though, so mouthing off for too long can be punished with physical force. Not because we dislike talking, but we're realists. If we can't convince someone verbally, we know it, and then we shut them down physically. Much like rabid dogs are dealt with.
