If your goals are misaligned, you'll likely come away thinking that you communicated but you might be being manipulated - which depending on how good they are at it, you might not realize.
It is a challenge though when the situations are forced. If I'm forced to be in a situation that doesn't align with my goals (and also stroke my ego in a certain way that might not be obvious) I will subtly sabotage whatever is going on or horse trade with someone else so that I can get out of the work.
I wouldn't try and play the game theory approach (I assume you mean the prisoners dilemma style cooperate/non-cooperate primarily) with most sociopaths because while a lot of high functioning ones are really logical - we'll change the rules to make the advantage ours.
