Query: Neutrino Mass Anarchy   What is the form of the neutrino mass matrix which governs the oscillations
of the atmospheric and solar neutrinos? Features of the data have led to a
dominant viewpoint where the mass matrix has an ordered, regulated pattern,
perhaps dictated by a flavor symmetry. We challenge this viewpoint, and
demonstrate that the data are well accounted for by a neutrino mass matrix
which appears to have random entries.
