This is an erratum to The Effect of Noise on the Emergence of Continuous Norms and its Evolutionary Dynamics , published in the Proceedings of the 2023 Conference on Artificial Life. After publication, we discovered an error in the mutation operator. In this correction, we will describe the error, outline what dynamics would produce the results we initially presented, and then compare them with simulation results with the mutation operator working as described in the original paper. We go through the claims of the original paper, discussing any possible differences in the outcomes. Overall, the main results of the paper still hold, although with some minor differences.
