I don't think you clearly understand what 70% means. If you call 70% and it doesn't go the other way three times out of ten, you were poorly calibrated. A lot

I don't think you clearly understand what 70% means. If you call 70% and it doesn't go the other way three times out of ten, you were poorly calibrated. A lot of people seem to have read 70% as "no worries", which is simply wishful thinking, and now are blaming Nate Silver for being "wrong". If your doctor told you you have a 70% chance of surviving the week, you probably wouldn't call that a "sure thing".
