Title: Free Information Flow Benefits Truth Seeking,
Abstract: How can we approach the truth in a society? It may depend on various factors.
In this paper, using a well-established truth seeking model, we show that the
persistent free information flow will bring us to the truth. Here the free
information flow is modeled as the environmental random noise that could alter
one's cognition. Without the random noise, the model predicts that the truth
can only be captured by the truth seekers who own active perceptive ability of
the truth and their believers, while the other individuals may stick to
falsehood. But under the influence of the random noise, we strictly prove that
even there is only one truth seeker in the group, all individuals will finally
approach the truth.
