How to effectively promote the level of fairness thus becomes a significant issue to be addressed. Here, by adopting a pinning control procedure, we find that when a very small fraction of individuals are pinned to be fair players in the Ultimatum Game, the whole population unexpectedly evolves into the full fairness level.
