I've seen this proposed (in a meme ): Him: I've got a place picked out for us to eat. Her: Where are we going? Him: Guess. Her: *makes a guess* Him: That's right, good guess. (proceed to go there) Luckily I've never had to employ any fancy tactics. My wife is extremely easy going, and is happy to go eat just about anywhere. In truth, I'm far more picky than she is.
I think it depends on the psychology factor. If people have the option to flee, then many will when the Silverback absolutely stomps the first few guys to enter the fray. If the men have no choice and no escape, and we consider them to be essentially immune to psychology / unbreakable, then I think they have a fair chance.
