Expected Utility
On Tau there is a feature discussed called the "opinion map". This "opinion map" can be translated easily into a "preference map". Every participant can simply rank the outcomes by giving numbers to track the level of desirability to weight to an outcome. This would allow a participant to output to Tau their preference map. This preference map would then be able to be used in generating game theory for Tau Agoras. Because one of the primary features of Tau is to be able to map and scale discussion it should be possible for Agoras to have the "best" game theory according to the current opinion map and preference map.
Which outcomes do the majority of the community prefer?
By having a preference map we could always know which outcome is most preferred. For example most rational actors want to get the most amount of win for the least pain. The exactly definition of win depends on the game being played but one assumption is every player wants to win. If we assume this as a rule, we could design games (game theory) with this understanding built in, without having to manually do it because Tau itself would hold us to that rule or to any of the rules of known game theory. A game theory knowledge base for example (assuming it's possible to construct) would be one of the better ideas for an initial base to build for Agoras.
Could we query a game theory knowledge base while building Agoras?
Imagine if while building Agoras there is a game theory knowledge base so that a basic understanding of economics, game theory, and psychology, is built into any Agoras which evolves? If in our discussion we can simply link to a knowledge base for game theory then we could for example build with all this knowledge without having to each individually understand it. This could be an Agoras specific feature if it gets built.
