Abstract
One puzzle of neutrino masses and mixings is that they do not exhibit the kind of strong “hierarchy” that is found for the quarks and charged leptons. Neutrino mass ratios and mixing angles are not small. A possible reason for this is proposed here. It is based on the fact that typical realistic grand unified models contain particles with unification-scale masses which, when integrated out, can yield a neutrino mass matrix that is not of the standard see-saw form.
