Description
We study noisy majority-rule dynamics on annealed hypergraphs with random group sizes. Using mean-field theory and Monte Carlo simulations, we show that group-size heterogeneity strongly influences collective ordering, the ordering threshold, and consensus times. Broad and heavy-tailed distributions enhance the effect of rare large-group interactions, making ordered states more robust against noise and potentially accelerating consensus formation. Our results highlight that the full distribution of interaction sizes, rather than only the mean group size, is a key factor in higher-order collective dynamics.
