Thank you! It's been said here before (by Robin Hanson among others) that the art of rationality as set out so far is a lonely art, and that's an artifact of how it was developed. In practice, it seems likely to me that even with the most desperate effort I could easily leave some central mistake like a detached lever at the heart of some complex of ideas, and someone else is going to have to point it out. We need to start thinking now about how to avoid the irrational diseases of groups, because groups can do so much to counteract the irrational diseases of individuals.
