And, just to be clear, in their paper it not the presence of noise that kills people, it is their treatment of noisy measurements as high-confidence measurements that kills them. When you get low confidence reads from data you should use them as such; the authors just act on them no matter how strong (or weak) the confidence and report what happens. It's roughly analogous to a doc saying "should I deviate from the baseline treatment?" and when the data say "dunno" the doc prescribes a totally random medicine rather than the baseline, because that is what "dunno" means.
