This is my reflection on how Predictive Markets harness the wisdom of crowds, and why they might be one of the most important tools Africa — and the world — needs right now.

In a time where technology is moving faster than governance, and truth is often lost in the noise, Predictive Markets stand out as a rare system that harmonizes decentralized participation with centralized insight.

They tap into the Wisdom of Crowds — and they work.

Decentralization empowers the individual, but centralization of information reveals the truth.

Let’s break it down.

The Wisdom of Crowds — What It Really Means

In The Wisdom of Crowds, James Surowiecki introduces a powerful idea:
