You really are narrow minded sometimes. I posted the AI bit, not to prove you right( although we know you always think you are, or BKB wouldn't have caught on), but to show how you cherry pick. If I wanted to show the OBR to be good. I wouldn't have bothered with the "not so good" bits. You, however pick one item and try to run with that as proof they are crap across the board, which appears to be not the case.
If you had said the OBR is generally OK with forecasting but poor on productivity forecasting, then you get some credibiity and context into the discussion, but no.
But if it makes you feel good about yourself coming from a totally non-balanced starting point, crack on, I'm glad you're glad.
I'm just looking for your scathing posts about forecasters getting inflation wrong by 0.2% over the period of a single month.
Anything constructive to say on putting things right?
