The validity of Nick’s promises may be extremely dubious, especially considering that he has very little incentive to go through with splitting the money after the show. In this situation, when one calculates the average outcomes, it makes more sense to choose to steal. On this episode, the two finalists, Ibrahim and Nick, began their discussion before choosing to split or steal. In fact, the unedited version of the entire discussion was around 45 minutes long. The clip above from the British gameshow, Golden Balls, shows the dilemma at it’s best. These questions are put to the test on the British TV game show called “Golden Balls”, which ran from 2007 to 2009. Golden Balls Revisited via Radiolab 07 Apr 2014 . However, Nick takes a different position. Would you deceive them instead and take the money for yourself? Nick’s narrowing of Ibrahim’s decisions combined with his refusal to compromise angers Ibrahim, and the discussion is fairly contentious. Kevan Ibrahim responds, “no, never.” Even after giving a speech about the value of a man’s word and promising that he will stick to his word, Ibrahim had never intended to cooperate and choose split. If it hasn’t become apparent by this point, the decision the contestants are faced with is known as the prisoner’s dilemma. Each time the contestants struggle to get them open, I wonder "Is that the best design they could come up with?" Your email address will not be published. Therefore, the entire possibility that Nick lied can effectively be ignored, as Ibrahim has no optimal strategy in this case. Would you trust a complete stranger to cooperate with you when money is on the line? So, as it turns out, communication and weird, counter-intuitive promises can, in fact, lead to outcomes that make everyone happy! This change does not directly affect the payoff matrix, but is one of the key differences, since this change allows people to change each others’ payoffs and strategies by making promises. However, due to the weirdness of this situation, the “sucker stigma” payoff is eliminated (it came from a social construct, and this situation is entirely out of the realm of social norms), so even if Nick lied, the game reverts to the original matrix, which is not a strict Prisoner’s Dilemma: if Ibrahim knows that Nick is going to Steal, he does not do better by choosing either strategy. If both parties choose to split, they each get half of the jackpot earnings. Radiolab followed up with both participants to find out what was going on behind the scenes and in their heads. As a final thought: Ibrahim reveals to RadioLab that he would have, in fact, chosen to Steal, as would have been his optimal strategy in the “sucker stigma” matrix. In a Radiolab interview about this episode, Ibrahim was asked if he would have chosen to split knowing that Nick was also going to split. This is because each finalist has a choice: split or steal. A couple weeks ago, Radiolab did a segment on a British game show that lasted three seasons, called Golden Balls. Ibrahim suggests that they both pick split instead, but Nick refuses. With help from Nick Corrigan and Ibrahim Hussein, we take a closer look at one of the strangest moments in game show history. The main part of the show is about people adding money in various ways to the jackpot, but the very last segment of the game is a sort of Prisoner’s Dilemma among two finalists: they can each choose to “Split” or “Steal” the money. game theory, —Huffduffed by Game theory is awesome and so is the prisoner’s dilemma. The jackpot will either go to only one of the two contestants, be split in half, or be lost by both players. The result was a show that could shake your faith in humanity—until one mild-mannered fellow unveiled a very unusual strategy, and suddenly, it was a whole new ball game. So what ends up actually happening on the show? Executive producer Andy Rowe explains how the show used a whole lot of money and a simple set of rules to force us to face the fact that being good might not end well. When they open their golden balls to reveal their decisions, Ibrahim has chosen split; Nick has also chosen split. Tagged with The players are named Nick and Ibrahim, and the jackpot is £13600. Why is college football back during COVID-19? golden balls After several rounds involving strategizing, cooperating, and lots of golden balls, the final round consists of an all-or-nothing decision between the two finalists. This payoff matrix leaves Ibrahim to choose between two choices, and clearly, the better option is to Split the money.
