Not all opinions should count equally on every question. The goal is not democracy of views; it is accuracy of outcomes.
Believability weighting means giving more influence to people who have demonstrated good judgment in the specific domain at hand. Credibility comes from track record, quality of reasoning, and an ability to learn from mistakes.
This reduces the cost of ego. People can still speak freely, but decisions are guided more by evidence than by hierarchy or charisma. Disagreement becomes more productive: instead of arguing endlessly, you ask whose thinking is most reliable here—and why.
Believability is not permanent. It changes with performance and learning. When that is understood, the system becomes fairer than politics because it rewards reality-based competence and visible reasoning.
