  • Like it or not, political season is upon us. This is going to be the most expensive political

  • season in the history of ever -- so you KNOW strategists on every side are going to try

  • and gain the upper hand... But how?

  • If youre staying on top of how the 2016 presidential election is shaping up, you will

  • likely hear from political strategists talking about the best way for a candidate to win.

  • A lot of times theyll throw around the termgame theoryand how it’s the

  • key to success. WHAT IS IT

  • Game theory is a way to look at all the possible outcomes of a rule-based interaction, whether

  • that's a game of Monopoly or political battle,,and then pick the ones that are the most advantageous.

  • When I was researching this principle, my first thought was the logic of a chess match.

  • Knowing the rules, a good player can determine the moves their opponent will make and then

  • make decisions on what to do. Game theory does the same, but with the rules of human

  • interaction.

  • It started as a mathematical theory for economics -- invented by John Nash of A Beautiful Mind

  • fame, and John Von Neumann. But nearly every human interaction you have can be described

  • by game theory. Every. Thing. If you're eyeballing the last slice of pizza, you're doing game

  • theory to figure out if you should take it. If you are talking to a business partner about

  • salary, you're using game theory. If you're asking someone on a date: game theory!! It's

  • everywhere! You can distill it into one simple idea: what's the best way to get the ideal

  • payoff with minimal risk.

  • The most famous example used for game theory is "the prisoner's dilemma." Two prisoners

  • are being interrogated in separate rooms, and their fates are intertwined. Sound familiar?

  • It's used in movies and tv all the time. The prisoners have the option to be silent or

  • snitch on their fellow prisoner. It helps to create a matrix like thisand fill it in

  • as we go. If one snitches and the other is silent -- the snitch goes free; but if they're

  • both silent (or both snitch), they'll see varying levels of reduced punishments. Put

  • another way, think of the Cold War. The US and Russia had two choices, arm or disarm.

  • Logically, they'd want to disarm, save money and have no war, but because that's mathematically

  • unlikely, the rational choice was to arm, because they will either maintain superiority

  • (because the other disarms), or equality (because they both arm)!

  • THE TRICKY PART FOR CANDIDATES Game theory attempts to explain why rational

  • people, organizations, businesses or governments may not cooperate, even though it may be in

  • their mutual best interest. When it comes to running for president, the rules and players

  • are there, but how each candidate chooses where to campaign can come down to game theory.

  • For a practical example, let’s use the candidates from U.S. presidential election in 2004. In

  • an article for Slate, University of Wisconsin math professor Jordan Ellenberg did some math

  • for us, thank goodness: So let’s say George Bush and John Kerry have only one more day

  • to make a stopand Florida and Ohio are key swing statesThe Bush campaign can

  • use Game theory to figure out which state to visit.

  • If Bush has a 70 percent chance of winning Florida and only 30% chance in Ohio, where

  • should he go? By visiting a state he'll get a 10% bump. Our gut tells us, he should go

  • to Ohio so he can boost his numbers there, but is that right? Game theory has the answer.

  • If both Bush and Kerry go the same state, Bush has a 21% chance of winning the overall

  • election. If Bush visits Florida and Kerry Ohio, he drops to a 16% chance of winning,

  • but if Bush goes to Ohio and Kerry goes to Florida, then his chances of winning jump

  • to 24%. So, his "dominant strategy" is to go to Ohio and ignore Kerry, because he'll

  • either get a 24 or 21 percent chance of winning. Laying out the strategy for both players,

  • is called the "Nash Equilibrium." Which says both would be satisfied with their current

  • strategy even knowing in advance their opponents strategy. This helps because candidates don't

  • always know what the other is going to do, and the rules of the game are rarely so straightforward.

  • Now that the 2016 Presidential Election season has begun, Republican candidates are each

  • trying to unseat the other to win the GOP nomination. Game theory doesn't provide solid

  • answers, but gives rational thought to what can be emotional decision-making. By guessing

  • all the possible paths of current frontrunner Donald Trump[7] the other candidates may have

  • gotten more benefit from letting Trump come off as a bully, rather than fighting him on

  • policy or rhetoric.

  • By running game theory each campaign can increase their chances of coming out on top. It might

  • be too early for the candidates to have all the rules of the 2016 election set in stone,

  • but like in chess, each candidate is trying to decide what the other candidates are doing,

  • and what moves each can make, to give themselves the greatest advantage.

  • Obviously, this can get WAY complicated WAY fast, but it's super interesting. If you know

  • more about game theory, teach us your ways down in the comments.

Like it or not, political season is upon us. This is going to be the most expensive political
