doug will remember, douglas holtz-eakin wrote in the new york times that the real number was going to add to the deficit by $562 billion. his estimate and the cbo estimate were off by $700 billion. so what i'd argue is that the cbo should express uncertainty in scoring. and i have to say -- and this is controversial. okay. i give a talk at the cbo a couple years ago about this. cbo has established an admirable reputation for impartiality. maybe it's best to leave it alone and just continue things as they are. i worry, though, and maybe this is just my being an academic from the outside who doesn't understand washington, but i argued that there's been a social contract to accept cbo estimates. i worry that social contract is going to break down at some point, someone will dig in, in congress or the media or dig in and find some estimate from the cbo they don't like, ask how the sausage was put together, and then say, well, you know, who knows. and then this cbo's reputation will go. i would rather the cbo face up to this, and provide uncertainty in its scoring measures. very simple way
