the possible prisoners' dilemma where the technology works out so that to maximize expected IQ you have to expose the genetically engineered babies to a huge risk of nasty genetic conditions
Why is this a prisoner's dilemma? An arms race is a different kind of a game.
It would be a prisoner's dilemma like game if both sides would prefer to have a binding credible agreement in which no one takes huge chances with the tech, but since you would expect the other side to cheat (and would cheat yourself even if you knew the other side wouldn't) you use the tech.
I suggested recently that part of the problem with with LW was a lock of discussion posts which was caused by people not thinking of much to post about.
When I ask myself "what might be a good topic for a post?", my mind goes blank, but surely not everything that's worth saying that's related to rationality has been said.
So, is there something at the back of your mind which might be interesting? A topic which got some discussion in an open thread that could be worth pursuing?
