Math for figuring out what people will do when everyone's trying to outsmart everyone else.
means The mathematical study of strategic decision-making, where the best choice depends on what everyone else is expected to choose.
from The field was formalized in the 20th century, most famously by mathematician John von Neumann and economist Oskar Morgenstern, whose 1944 book 'Theory of Games and Economic Behavior' treated competitive and cooperative situations — originally parlor games like poker and chess — as rigorous mathematical objects. The word 'game' here is deliberately broad: it covers anything from literal games to war, auctions, and evolution, wherever outcomes depend on the choices of multiple self-interested players rather than chance alone.
