An idea that regularly pops up on LessWrong is making a rationality video game ... it's been discussed in the threads here:
http://wiki.lesswrong.com/wiki/The_Less_Wrong_Video_Game
I've been rereading those threads and there are some interesting ideas, though there's also stuff that sounds like a lot of effort to develop and wouldn't deliver much rationality bang for the buck.
How about a new round of kicking ideas around?
For example, how could a game teach someone to not deceive himself? That would require:
1) A situation in which one is likely to deceive himself because of a specific bias (the conjunction fallacy, confirmation bias, hindsight bias, etc.)
2) A game system that rewards overcoming the self-deception (either because it is detected by the system - which is hard! - or because true beliefs are instrumentally useful in the system)
This seems significantly harder than the cleverness/deduction games (like mastermind, minesweeper, Professor Leyton, etc.). One approach is to focus on calibration, and measure something that the player has reasons to get wrong to give a better image of himself (for example, chances of completing an angry-birds-like level in less then three tries, or confidence in one's answer to a trivia question). Another approach is to take a fully scripted path, with a story where one could expect the player to be biased, and then have a revelation - which is nice, but is a bit of a one-trick poney.
It seems that each bias would require a special game mechanic (some of which would be quite hard to design - hindsight bias???), and players may be more likely to just learn how to game that particular mechanic through trial-and-error without overcoming the underlying bias.
Maybe just going through
http://en.wikipedia.org/wiki/List_of_biases and coming up with game ideas would work. And there are also rationality skills that aren't about a specific bias ...
Thoughts? What kind of rationality games have you made, or have you thought of?
