I think a goose is a lot like a rooster, in that they both would like very much to be the one in charge. And if you let them, they will happily take on the role as foreman. It has been my experience however, that both aggressive geese and roosters will settle down and fall in line after a few times of being seized by the neck and flung up against a tree, or thumped on the ground. It's been a few years, but I've had to do it a couple times in the past.
If we're talking about a child or smaller adult, or if it's obvious to the bird that you're intimidated by it, then it has the upper hand.
