The latest cosmological constraints on the sum of neutrino masses, in combination with the latest laboratory measurements on oscillations, provide a “decisive” Bayesian evidence for the normal neutrino mass hierarchy. We show that this result is robust to the choice of prior by exploring two extremes on the range of prior choices. For Majorana neutrinos this has important implications for the upper limit of the neutrino-less double beta decay half life and thus for the technology and resources needed for future double beta decay experiments.
