Abstract
Simulation data on Ising spin glasses in dimensions 3, 4, and 5 indicate that the critical exponent \ensuremath{\eta} changes with the form of the interaction distribution, which appears to be a pertinent parameter for the spin-glass transition. This result is incompatible with standard second-order transition universality rules which do not seem to hold for Ising spin glasses.
