If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
How does this differ from the rationalization game?
I am not sure. A quick search on LessWrong only lead me to Meet Up: Pittsburgh: Rationalization Game
What I am proposing would be more of an exercise in argument structure. Either the 'facts' are irrelevant to the given argument or there are more 'facts' needed to support the conclusion.
