Vitalik Buterin discusses Credible Neutrality in the context of Incentivised Mechanisms of guiding human behavior.
"... there is a very important principle that is at play, and one that is likely to become key to the discourse of how to build efficient, pro-freedom, fair and inclusive institutions that influence and govern different spheres of our lives. And that principle is this: when building mechanisms that decide high-stakes outcomes, it’s very important for those mechanisms to be credibly neutral."
