@vrandecic yes, I agree it's disappointing Denny. I can report this issue internally to the teams that have a chance of patching this particular failure mode if you want?

IMHO it would be good if Google supported something like community annotations for claims. But right now each generated answer is wholly independent and can't even be saved for later reference it would seem. There are only individual ratings available, which are presumably used for RLHF.
