Why does deadlock rule Congress? Why do scientists say that we can’t solve climate change through individual action alone? If any of the previous questions intrigue you, come to a crash course on applied game theory! Here, we'll introduce you to the science of strategy, formally known as "Game Theory." We'll see how the forces of game theory shape our society and everyday interactions, using climate change as a case study. Finally, we will talk about how we can use this interdisciplinary knowledge to make change that is not just moral but also effective.
