In the absence of other evidence, could you not use some sort of complexity measure to estimate that, if our universe is being simulated, the simulating universe is more likely to have simpler laws than more complex ones? (And maybe even that having no simulating universe—meaning our universe is not a simulation—is even simpler, and therefore more likely?) But I have no idea what the actual difference in probabilities would be, if you could.
