We report multicanonical Monte Carlo simulations of the tails of the order-parameter distribution of the two-dimensional Ising model for fixed boundary conditions. Clear numerical evidence for “fat” stretched exponential tails is found below the critical temperature, indicating the possible presence of fat tails at the critical temperature.
