We come, at last, to the final subsection of our “worldbuilding” series. Having touched on biology, culture, and the mind, we now turn back to a slightly more abstract topic: game theory. More generally, we are going to be looking at how people make decisions, why they make the decisions they do, and how these decisions tend to play out over the long term.
This topic draws on everything else we’ve covered in worldbuilding. In hindsight, understanding human decision-making was really the goal of this whole section, I just didn’t realize it until now. I’m sure there’s something very meta about that.
Game theory is traditionally concerned with the more mathematical study of decisions between rational decision-makers, but it’s also bled over into the fuzzier realms of psychology and philosophy. Since humans are (clearly) not always rational, it is this fuzzy boundary where we will spend most of our time.
The wiki article on game theory is good, but fairly math-heavy. Feel free to skim.
