It's not just a question of instrumental error though. There are also assumptions being used in interpreting the data from the instruments, and it's not generally possible to assign them reliable probabilities.

e.g. the first line of the article's abstract quoted above:

"Supernova (SN) cosmology is based on the key assumption that the luminosity standardization process of Type Ia SNe remains invariant with progenitor age."

If the results reported in the article are right, the confidence we should have in this assumption, and therefore any results relying on it, have just radically changed.

That's moving the goal post. I was specifically responding to concerns about fuzzy data.

It's true that assumptions have to be made, and those can and should be questioned, but that wasn't the concern of the comment I replied to.

My concern is model accuracy holistically; analyzing likelyness-to-be-correct including all assumptions; I think the post you are responding to is in context.
