In the Voter Model, each agent adopts the opinion of a random neighbor at each step. Without zealots, the system reaches consensus (one opinion wins). Zealots are agents that never change opinion — they create a sustained minority. Even a small zealot fraction can prevent consensus and shift the stationary distribution, modelling committed minorities in social influence.
