There's a TV show in the UK called Golden Balls. It's not very good to be honest. Every episode ends in a classic Prisoner Dilemma (apart from the fact the contestants get to talk to each other). This clip has surfaced recently of a dude playing a very clever position, which doesn't happen very often as they generally pick contestants who could barely spell game theory, let alone apply it. Heres a link to the clip and a blog about it:
Very interesting psychology. Nick convinces Ibrahim that he is going to steal, and therefore Ibrahim's only choice is they both lose (Ibrahim steals) or Nick wins everything (Ibrahim splits) - but also that if Nick wins (Ibrahim splits), Nick will give Ibrahim half after the show. Nick has pyschologically forced Ibrahim's choice: the only rational choice is for Ibrahim to split, so Nick can now pick the best option for himself. However, Nick turns out to be both trustworthy and untrustworthy: he changes his choice to split, but this means they both share the winnings officially instead of on a gentlemen's agreement.
Well, it's a common phrase that has been used for different things.
