Game Theory "is the study of mathematical models of strategic interaction among rational decision-makers" (-- Wikipedia). It started in economics but has long since been developed, expanded, and adapted for other field of study: sociology, biology, and AI/CS, just to name a few.
I've curated a list of 5 different "items" that may make you interested in this topic... Well, they did for me.
The Evolution of Trust
This is one of Nicky Case's "Explorable Explanations" (think, educational games).
The Evolution of Trust is an interactive presentation about game theory and the problem of 'trust' between people. It features multiple agents, each with a different strategy/approach to cheating and cooperation.
It's simply one of the best colorful introductions to game theory.
It's open source and can be played directly on the developer's website: ncase.me/trust
Liar Game is a manga and a Japanese drama series.
The story revolves around a trusting and gullible girl named Nao, who finds herself participating in a dangerous game, where the players need to steal each other's money by cheating and manipulating one another. Cheaters gain huge sums of money, while the rest find themselves in debt for life.
She gets help from a cool, ex con artist named Akiyama who plays along her side, and they both level up through increasingly difficult stages of the game.
Nao's naivety highlights Akiyama's intelligence and his use of game theory principles (and mathematics in general) to outsmart their competitors and enemies.
The Red Queen: Sex and the Evolution of Human Nature
The Read Queen by Matt Ridley is a 'pop science' book about sex and evolution, and how Nature's "arms race" gives rise to the different behaviors we see in animals and tries to explain some aspects of the human condition.
This book is both humbling and interesting as it presents multiple --and sometimes contradictory-- scientific hypotheses. A must read.
Compulsive Gambler (Kakegurui)
Kakegurui is a manga and anime about a "compulsive gambler" girl who transfers to an elite school where gambling is the law of the school.
This anime shows you what might happen when an intelligent agent who's capable of seeing through gambling scams, decides to play 'irrationally' by breaking rules and ignoring logical courses of action.
Hint: The disruption of systems, that's what happens.
If you like crazy girls and fan-service then this anime is for you; otherwise, it's a *meh*.
Murder by Numbers
Murder by Numbers is a 2002 detective film.
Plot: After a long chase filled with mind games, Prisoner's Dilemma is used against two school students, suspected of having executed a "perfect" murder.
If not for the Prisoner's Dilemma, then watch it for the sake of Sandra Bullock who played the "hyena" detective role.
