Hi, neutrino physicist here. There are indeed a handful of results that point to a more-or-less consistent picture with sterile neutrinos, including MiniBooNE (now updated with 2x more data), LSND, antineutrinos from nuclear reactors, and calibrations of solar neutrino experiments (GALLEX/GNO and SAGE). All very different experiments with different uncertainties, which makes it hard to explain away. Meanwhile, there are a bunch of other experiments that should see this effect but don't (IceCube and MINOS, KARMEN, NOMAD, CDHS, CCFR, ...). With all this tension, most of the possible parameters for sterile neutrinos are ruled out, but there is still a little room. Next-generation experiments will go after the parameter space that remains, and definitively confirm/reject the sterile neutrino hypothesis at high confidence. See e.g. the Fermilab Short-Baseline Neutrino Program, which puts a set of three detectors in the same neutrino beam as MiniBooNE: https://sbn.fnal.gov/.
