Does anyone have any good brief ways of describing LW to outsiders that have been effective? This comes up quite a bit for me with friends and family.
I think the most effective rhetorical technique would be very sensitive to the kind of person you are describing it to. I don't know if it is good, but I once said something like "it is about how you can avoid certain kinds of errors in your thinking, so that you can make better decisions".
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
