Query: Sterile Neutrino Anarchy   Lepton mixing, which requires physics beyond the Standard Model, is
surprisingly compatible with a minimal, symmetryless and unbiased approach,
called anarchy. This contrasts with highly involved flavor symmetry models. On
the other hand, hints for light sterile neutrinos have emerged from a variety
of independent experiments and observations. If confirmed, their existence
would represent a groundbreaking discovery, calling for a theoretical
interpretation. We discuss anarchy in the two-neutrino eV-scale seesaw
framework. The distributions of mixing angles and masses according to anarchy
are in agreement with global fits for the active and sterile neutrino
parameters. Our minimal and economical scenario predicts the absence of
neutrinoless double beta decay and one vanishing neutrino mass, and can
therefore be tested in future experiments.
