Secret Goals

First off, apologies for the long absence; life has a habit of getting in the way of philosophy. Back to decision-making and game theory.

Now, obviously whenever you make a decision you must have certain goals in mind, and you are trying to make a decision to best fit those goals. If you’re looking at a menu, your goals may be to pick something tasty, but not too expensive, etc. You can have multiple goals, and they can sometimes conflict, in which case you have to compromise or prioritize. This is all pretty basic stuff.

But what people tend not to realize (or at least, not to think about too much) is that frequently our “goals” are not, in themselves, things we value; we value them because they let us achieve bigger, better goals. And those goals may be in the service of even higher goals. What this means is that all of these intermediate layers of “goals” are really just means that we use so frequently we have abstracted them into something that we can think of as inherently valuable. This saves us the mental work of traversing all the way back to the root wellspring of value each time we want to pick food off a menu. The result is these layers of abstract “goals”. Yet another set of layers of abstractions!

So what are these root goals we tend not to think about? Are they so-called “life goals” such as raising a family or eventually running your own company? No. Those are still just intermediate abstractions. The real goals are still one more step away, and are almost universally biological in nature. The survival and reproduction of our genetic code, whether through ourselves, our offspring, or our relations. These are our “secret goals”.

So how does this help us understand decision-making? It seems intuitively impossible to understand somebody’s decisions if we don’t understand the goal of that decision. But when we think exclusively in terms of our shorter-term, abstract “goals”, these are things that change, that we can abandon or reshape to suit our current situation. Thinking of these instead as methods of satisfying our underlying goals (which do not change) provides a much more consistent picture of human decision-making. This consistent picture is one to which we might even be able to apply game theory

Game Theory

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.
