# Free Information Flow Benefits Truth Seeking

## TL;DR

This paper demonstrates that persistent free information flow, modeled as environmental noise, ensures that all individuals in a society will ultimately approach the truth, even with only one active truth seeker present.

## Contribution

It introduces a model showing that environmental noise facilitates universal truth-seeking in society, extending previous models that required multiple truth seekers.

## Key findings

- Environmental noise guarantees convergence to the truth for all individuals.
- A single truth seeker can lead the entire society to the truth under noise influence.
- Without noise, only truth seekers and believers reach the truth.

## 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.
